Abstract:
An apparatus and method for cutting three dimensional parts in a rotary die cutting mechanism (100) is provided including first and second drums (101 a,b) adjacent to each other to rotate about a respective axes, first and second recesses (106 a,b) formed on an outer surface of each of the drums in order to receive a three dimensional part, an anvil (103) protrudes outward from an edge of the first recess, and a cutting mechanism (104) protrudes outward from an edge of the second recess, the three dimensional part retained in a proper orientation to allow the three dimensional part to be cut by a first and a second capturing mechanism (105 a,b) disposed within the first and second recesses (106 a,b) respectively, configured to move in relation to the rotation of the drums (101 a,b).
Abstract:
A thermoforming trim press has one or more connecting arms for a movable platen which each have a pivotal connection between the adjacent ends of two adjacent sections into which each connecting arm is divided. The pivotal connection is normally locked to keep the sections in end to end alignment during normal press operation, but can be released to allow pivoting between the sections to be able to draw the movable platen further back from the normal retracted position to increase the available clearance when changing or maintaining tools mounted on the movable platen. The pivoting ability of the connecting arm sections also simplifies adjusting the stroke of the press while this is normally done by relocating a crank pin on flywheels driving the connecting arms. The change of position does not affect the movable platen when the arm sections may pivot with respect to each other allowing relocating the crank pins to adjust the stroke without requiring disassembling of the crank pins. A counterweight may be driven by the crank pins to match the press stroke adjustments and to thereby correspond the movement of the counterweight to the movement of the movable platen.
Abstract:
Disclosed is a full-automatic method for manufacturing plant-fiber molding products and margin trimming and molding machines. The invention achieves functions: wet semi-finished product forming, hot press mold solidifying, and automatic margin trimming. The full-automatic method is as below: pulps are continuously made into wet semi-finished products by means of a suck-filter forming device, which is alternatively fed into hot-press molds of the left hot-press mold solidifying device and the right hot-press mold solidifying device after being heated to a certain temperature in hot-press molds for hot-press drying and solidifying. The dried and solidified products fall into the left positioning collecting tray and the right positioning collecting tray respectively from the left hot-press top mold and the right hot-press top mold, and are positioned therein. The full-automatic plant-fiber molding, mold solidifying and margin trimming machine includes a forming and solidifying device, a transfer device and a margin trimming device.
Abstract:
A mold for stamping and overmolding inserts made of composite material is disclosed. The mold includes a first and a second half-mold complementing one another and defining a space for reception and overmolding of the insert made of composite material. The first half-mold has at least one orifice inside which is placed a hole punch-forming blade borne by the end of a mobile support, to be able to cut the insert made of composite material, where the blade is also contiguous with the wall of the orifice. The second half-mold has an orifice facing the at least one orifice of the first half-mold, inside which is placed a plunger of corresponding form and contiguous with the wall of the orifice and mobile to be able to come into contiguous contact with the blade.
Abstract:
A molding device includes a male die, a master die core, a male die core located between the male die and the master die core, and a cutting mechanism received in the male die core. The cutting mechanism includes a cutting seat and a cutter. The cutting seat defines a latch slot. The latch slot includes a narrow portion and a wide portion communicating with the narrow portion. The cutter includes a plate body received in the narrow portion and a latch shaft located on the plate body. The latch shaft is engaged in the wide portion. When a plastic product is formed and a sprue gate is around the mold cavity, the plate body is configured to cut the sprue gate, and the plate body is movable relative to the cutting seat around the latch shaft, to prevent the plate body from sticking.
Abstract:
An end face of an intermediate layer of a multilayer structure is stably covered by surface resin layers at a time of cutting the multilayer structure. A cutting method of the multilayer structure includes the steps of: compressing and deforming the multilayer structure, while extending respective layers of the multilayer structure to provide a thin thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion, in a fused state of at least one of the resin layers forming the multilayer structure; and push-cutting the compressed thin thickness portion S till the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer and surface resin layers of the multilayer structure to the abutting portion A of the push cutter and the cutter receiving portion.
Abstract:
There is provided a deburring system for enabling perfect automation of deburring with which burr of a resin molded article is substantially perfectly removed after the resin molded article is manufactured at low cost not by using an expensive resin molding machine, but by using a conventional general-purpose molding machine. Furthermore, there are provided a deburring apparatus and a cutter blade with which burr of a resin molded article having an unstable shape can be easily and cleanly removed from the root thereof without using any expensive control device and any positioning device and also without using any expensive copying device.
Abstract:
An exemplary cutting apparatus for cutting a workpiece includes a base, a cutting device and a first driving device. The cutting device is movably mounted on the base. The cutting device includes a first blade and a first vibrator. The first blade is movable in a moving direction toward the workpiece. The first vibrator is configured for vibrating the first blade to increase a shearing force applied to the workpiece. The first driving device is configured for driving the first blade to move.
Abstract:
A thermoforming web cutting apparatus is provided with a frame with a guide post including a tapered outer surface with increasing cross-sectional dimension toward a closing position, a first support structure with a first cutting die, a second support structure with a second cutting die configured to scissor in intermeshing relation with the first cutting die, and a bushing having a tapered inner surface complementary and reverse to the tapered outer surface on the guide post and adjustable in cross-sectional dimension and configured to guide one of the first support structure and the second support structure for axial reciprocation along the guide post. A method is also provided.
Abstract:
Apparatus and process for trimming articles molded on a plastic sheet and successively fed from a forming machine. A carriage receives the article to be held thereunder by vacuum and is moved in a trimming zone, where a pair of longitudinal cutter devices, each having a stationary blade and an angularly movable blade, are horizontally moved together from respective retreated positions for longitudinal cutting. Then, a front transverse cutter device having similar pair of blades is raised up from a retreated position for transverse cutting and then a rear transverse cutter device is similarly operated.
