Modular plastic mold structure and design method thereof

Abstract

The invention provides a modular plastic mold structure and a design method thereof. An upper mold comprises n second upper mold modules, and upper mold forming portions are fixed to the lower portions of the second upper mold modules. A lower mold comprises n second lower mold modules, and lower mold forming portions are fixed to the upper portions of the second lower mold modules. A front mold comprises n second lower mold modules, and front mold forming portions are fixed to the rear portions of the second lower mold modules. A rear mold comprises n second rear mold modules, and rear mold forming portions are fixed to the front portions of the second rear mold modules. A mold cavity is defined by the upper mold forming portions, the lower mold forming portions, the front mold forming portions and the rear mold forming portions together. The upper mold, the lower mold, the front mold and the rear mold are combined through a mold assembly system of an injection molding machine, and the injection molding machine is used for performing injection molding on the mold cavity. According to the modular plastic mold structure and the design method thereof, modular design is conducted on a traditional plastic mold, different molds are formed by combining the different modules, the modules of certain structures can be applied to different plastic parts, the mold input cost is low, the time of path change is short, and the production efficiency is high.

Description

technical field [0001] The invention relates to a plastic mold structure, and specifically discloses a modular plastic mold structure and a design method thereof. Background technique [0002] Plastic mold is the abbreviation of a combined plastic mold for compression molding, extrusion molding, injection, blow molding and low foam molding. In industrial production, special tools used on various presses and loading presses are used to make metal or non-metallic materials into parts or products of the required shape through pressure. Such special tools are collectively called molds. Among them, the plastic mold is a tool for producing plastic products. It is composed of several groups of parts. There is a molding cavity in this combination. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic cup is injected into the molding cavity. The cavity is cooled and shaped, then separated from top to bottom, and the product is ejected...

AI Technical Summary

Problems solved by technology

[0003] Traditional plastic molds only design the upper mold and the lower mold. After the upper mold and the lower mold are closed, the injection molding operation is performed to complete the injection molding of the plastic part. However, the shape of the upper mold and the lower mold is fixed, and a set of molds can only For the production of one product, different products need to use different molds for production. The input cost of the mold is high, and the line change time is long, and the production efficiency is low.
