    摘要: An injection molding cooling core 10 comprises an elongated, hollow core pin 15 having an inner surface 16 and an outer surface 17. The core pin 15 is open at one end, and has an end cap 18 at an opposite end. The core 10 also has an elongated, hollow insert 20 having an inside surface 21 and an outside surface 22. The insert 20 has a plurality of protrusions 25 on the outside surface 22, which extend radially outwardly from the insert 20. The insert 20 is designed to fit within the core pin 15 whereby the protrusions 25 contact the inner surface 16 of the core pin 15. The protrusions 25 are metallurgically joined to the core pin 15 whereby there is a continuous metallurgical path for heat transfer between the outer surface 17 of the core pin 15 and the insert 20. The protrusions 25 also provide strength to the core pin 15 and a greatly enhanced heat transfer surface. The inside surface 21 of the hollow insert 20 defines a conduit for a heat exchanging fluid 29. The heat exchanging fluid 29 flows in a direction from the open end of the core pin 15, through the hollow insert 20, towards the end cap 18, exiting the hollow insert 20 near the end cap 18 and contacting the end cap 18, then flowing between the outside surface 22 of the insert 20 and the inner surface 16 of the core pin 15. The heat exchanging fluid 29 further achieves turbulent flow around the protrusions 25, then flows out of the open end of the core pin 15, thus providing heat transfer to or from the outer surface 17 of the core pin 15.

    摘要: Injection molding apparatus having a cavity insert (10) with integral inner and outer portions (136, 138) having a cooling fluid flow channel (166) extending therebetween. In a preferred embodiment, the cooling fluid flow channel (166) is formed by a groove (164) machined in the outer surface (162) of the inner portion (136). This brings the cooling fluid flow closer to the cavity (66) and improves cooling efficiency and reduces cycle time.

    摘要: A mold insert for an injection molding machine has a circumferential liquid conduit groove and a plurality of liquid-receiving bores extending inwardly from the groove. Baffles are removably inserted into the liquid-receiving bores and have heads located in locking engagement with the sidewalls, including the undercut portions thereof, to retain the baffles in their respective liquid-receiving bores. Each baffle has a blade that fits snugly within a liquid-receiving bore to separate the liquid-receiving bore into a liquid inlet passageway and a liquid outlet passageway. Fins project outwardly from opposite faces of the blade to create turbulence in liquid flowing into and out of the liquid-receiving bore, which enhances cooling (or heating) of the mold insert. The baffle is also useful with other solid components having a liquid conduit for cooling purposes and a transverse liquid-receiving bore intersecting the liquid conduit. An improved liquid barrier for use in preventing the flow of liquid in the liquid conduit groove is formed by a dam member substantially identical to the head of a baffle.

    摘要: Injection molding apparatus with each elongated cooled mold core (10) having a hollow elongated inner part (78) inside a hollow elongated outer part (80) and an integral dome shaped front cap (132). The outer surface (120) of the inner part (78) and the inner surface (126) of the outer part (80) each having cooling fluid conveying grooves (122, 128) which spiral in opposite direction. This provides very uniform cooling and forces the cooling fluid flow through the grooves (122, 128) to be very turbulent which increases cooling efficiency. It also gives the mold cores (10) additional structural strength to withstand higher injection pressures.

    摘要: Injection molding apparatus with each elongated cooled mold core (10) having a number of cooling fluid bores (118) or grooves (134) extending around a central cooling fluid duct (104). An integral dome shaped front cap (76) encloses the open front end (78). The inner surface (130) of the dome shaped cap (76) has curved ribs (132) which form curved cooling fluid grooves (134) aligned with the cooling fluid bores (118) or grooves (134). The curved ribs (132) give the dome shaped front cap (76) more strength which allows it to be thinner with the curved cooling fluid grooves (134) being closer to the cavity (66) to improve cooling efficiency.
