摘要： A cooling structure of a pressing mold (20) comprises an outlet (24) and an inlet (22), which are formed in a radial direction of the pressing mold. Furthermore, a cooling passage (26) is integrally formed inside the pressing mold in a hidden manner, and two ends of the cooling passage are connected to the inlet and the outlet, respectively. Also, the cooling passage, being a continuous structure, further has the position and curvature changing in correspondence with the circumferential direction and the axial height of the pressing mold. Furthermore, the cooling passage may be additionally formed inside a cooling ring (34) to be combined with an outer mold body (32) to form the pressing mold. Thus, the cooling passage is well closed, and the position changes of the cooling passage comprise the axial and circumferential directions of the mold or cooling ring, so that the larger cooling area and the good cooling effect are provided.

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： To avoid surface defects during the production of injection moulded plastic products, the surface temperature of the metallic mould is raised above the injection transfer temperature of the plastic resin when the resin is non-crystalline or above the fusion point temperature if the resin is crystalline, using a temperature increase rate greater than 2° C per second. This temperature is maintained during the resin charging period followed by cooling at a decreasing rate greater than 2° C per second after the completion of charging. The temperature control is conducted using a feed back control with a detector for determining the surface temperature of the metallic mould and mounted close to the surface of the metallic mould.
