摘要:
The present invention relates to a guiding and centering device (10) for a forming tool (2), in particular an injection molding or die-casting tool, comprising a first mold half (1) and a second mold half (5) which are guided by guide means (7) from a closed position in which the respective separating surfaces of both mold halves (1; 5) are pressed against one another into an opened position and vice versa. This guiding and centering device (10) comprises a protruding guiding body (4) formed as a circular cylindrical bolt (12) provided at the first mold half (1), a guiding recess (6) formed as a bush (14) with an circular cylindrical inner surface (20) provided at the second mold half (5) and a rolling element cage (16) with rolling elements (17) inserted in rows (18), by means of which the two mold halves (1; 5) are guided and precisely centered in the closed position. The rolling element cage (16) is supported by the circular cylindrical inner surface (20) of the bush (14) and positioned via positioning means (30) in such a way that when closing the forming tool the circular cylindrical bolt (12) runs practically simultaneously in a first row of rolling elements (18.1) and a second row of rolling elements (18.2) of the rolling element cage (16).

A positioning device for aligning and guiding a first half and a second half of a mold together. The positioning device may comprise a housing including identical wall members configured to define a cavity. Each of the wall members comprise a tab, the tab defining a recess and a protrusion on opposed sides of the tab such that the protrusion and recess defined by the tab of one of the wall member is configured to interlock with the recess or protrusion of the tab of an adjacent wall member to connect adjacent wall members. A first member may be slidably disposed within the cavity of the housing, the first member defining a void. The positioning device may further comprise a second member comprising a base and a protrusion, wherein the protrusion is configured to matingly engage the void of the first member.

An insert member includes a bending portion, a first portion, and a second portion. The bending portion is interposed between the first portion and the second portion. A device for integrally molding the insert member and resin includes a holding portion configured to securely hold the first portion, a surface configured to contact a bottom surface of the second portion, and a gate configured to inject resin from a position nearer to the first portion than to the second portion, into a cavity. The cavity has a shape which causes a flow speed of the resin in a space above the second portion to be higher than a flow speed of the resin in a space at a side of the second portion.

A molding device and a molding method are provided. The molding device includes an upper molding assembly and a lower molding assembly. The upper molding assembly includes an upper molding plate and a plurality of positioning columns disposed thereon. The mold core and a plurality of matching columns surrounding the mold core are disposed at the same side of the upper molding plate. The lower molding assembly includes a lower molding plate and at least one formation mold, wherein the lower molding plate has at least one accommodating groove, a plurality of matching grooves and a plurality of positioning holes surrounding the accommodating groove. The formation mold is disposed in the accommodating groove, and the formation mold has a formation cavity corresponding to the mold core. Each positioning column is disposed respectively into each positioning hole, and each matching column is disposed respectively into each matching groove.

A platen for use with an injection molding machine includes a body having an opening for receiving a ring protruding from a mold for aligning the body and the mold. The opening includes a tapered recess having a surface extending radially outward from the opening. The tapered recess defines opposed edges along an outer surface of the body, the opposed edges converging in a radially outward direction away from the opening.

A bubbler base or base body for accepting a bubbler tube that has an externally threaded section at one end of the bubbler tube. The bubbler base of this invention can be used to quickly attach the bubbler base already connected to a bubbler tube, without the need to form an internally threaded bore within a bottom clamp plate which is also referred to as a cooling plate and is conventionally known in the molding tool industry. A conventional bubbler tube can be attached to the bubbler base rather than to the bottom clamp plate or the cooling plate. The bubbler base can have an overall spool shape. An O-ring can be used to seal the bubbler base with respect to the bottom clamp plate or the cooling plate.

A positioning device aligns first and second mold segments moving from an opened position to a closed position. The device includes a female member for connecting to one of the mold segments and for receiving a male member connected to the other of the mold segments. A bearing mechanism is coupled to the female member for receiving the male member and reducing friction between the male member and the female member. One of the female member and the bearing mechanism includes a post extending transversely to the alignment axis and the other of the female member and the bearing mechanism defines a groove receiving the post as the bearing mechanism moves relative to the female member. The engagement between the groove and the post retains the bearing mechanism in the female member when the first and second mold segments move between the opened and closed positions.
