Shenzhen mold manufacturer, plastic mold structure basic knowledge plastic mold overall functional structure classification
Plastic mold is an indispensable tool in the processing of plastic products, and its structural design directly affects the quality and production efficiency of the final product. This article will discuss the structural basic knowledge of plastic molds and the classification of the overall functional structure.
The basic structure of the plastic mold can be divided into guiding system, support system, molding parts system, pouring system, cooling system, projector system and exhaust system according to its overall function. The guidance system is used to ensure the correct positioning and movement of mold parts, while the support system is responsible for supporting the mold structure. The molding parts system refers to the molded part, and the pouring system is a channel for plastic flow, including mainstream channels, diversion channels, gates and cold material holes. The cooling system is used to control the mold temperature, the projector system is used to push the molded parts out of the mold, and the exhaust system is used to exclude the gas in the mold.
As the main channel for plastic flow, the mainstream channel needs to consider the shape, slope, size and flow characteristics of the material when designing. The gate sleeve plays a role in positioning and keeping the plastic smooth. The shunt is the transition section between the main channel and the gate, and its design needs to take into account the section shape, size and feed balance. The gate is the part where plastic flows into the cavity. It has a variety of forms, such as inner gate, side gate, fan gate, etc. The location selection is necessary to avoid jet and creeping, and is conducive to gas discharge and fusion fastness.
The cold material hole is used to store the cold material head to prevent it from entering the cavity and affect product quality. Its structure includes the drawing form and the drawing hole design. The reasonable design and layout of these structures are crucial to the performance and production efficiency of plastic molds.
The structural design of plastic molds should take into account the coordination between functional systems to ensure the molding quality and production efficiency of plastic products. Through an in-depth understanding of the basic structure and functional classification of plastic molds, it can be better applied to actual production and improve product quality and production efficiency.
