Description

High-efficient demoulding structure of a section of thick bamboo is taken to injection mold's slider

Technical Field

The utility model relates to an injection mold technical field specifically is a high-efficient demoulding structure of a section of thick bamboo is taken to injection mold's slider.

Background

An injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. Injection molding is a process used in mass production of some parts having complex shapes. Specifically, the method comprises the steps of injecting molten plastic into a mold cavity from an injection molding machine at high pressure, and cooling and solidifying to obtain a formed product.

Screw post or other cylindrical mounting structure when car light part are regional at the slider, need demold from the slider when the die sinking and come out, but because the cylinder structure can shrink when the cooling, lead to gluing the position and adsorb completely on the slider, if the die sinking of forcing at this time can lead to the cylinder structure, even continuous product face is dragged deformation or damage, seriously influences the service function of product. In general, a slider spring needle is needed to assist demolding, but the spring needle needs to be pushed against a position capable of being stressed (such as a cross rib or a boss), if the area of a product except a cylinder is a plane or has assembly requirements and cannot be stressed, the spring needle effect will be weakened, and an ideal demolding effect cannot be achieved.
