Technical field

The utility model belongs to the technical field of multi-cavity molding molds, and in particular relates to a slider slide-out structure of a multi-cavity molding mold.

Background technique

Injection molding refers to the use of the extrusion and moldability of plastics to send loose particles or powdery molding materials from the hopper of the injection machine into the high-temperature barrel to heat, melt and plasticize them, turning them into a viscous fluid solution. Driven by the high pressure of the plunger or screw, the injection is injected through the nozzle at the front end of the barrel into the closed mold with a lower temperature at a high flow rate. After a period of pressure holding and cooling, the mold can be released from the mold cavity by opening the mold. Plastic products of certain shapes and sizes. Multi-cavity molding molds often use needle valve full hot runner and open hot runner molding. Since the mold is developed with multiple cavities, the total molded weight of the product does not match that of the same level of injection molding machine, and a higher-level injection molding machine is required for molding. The reason The mold is developed for a multi-cavity structure, and the mold width is often limited by the width of the injection molding machine after the slider slides out.
