Description

A plastic molding mold with functional modules

technical field

The invention relates to a mold, in particular to a plastic forming mold.

Background technique

At present, the production process steps of thermoplastic plastic products mainly include: the injection molding machine plasticizes and melts the material under high temperature and high pressure; There are several steps such as the pressure keeping, the cooling of the product in the mold, the opening of the mold and the removal of the product.

Injection molding products often have the following problems in the production process of each process: 1. The edge gate and edge lap gate of the plastic product cannot be separated from the plastic product automatically; 2. For parts with holes or grooves For plastic products, during the injection process, the molten material will flow through the two sides of the hole or groove and meet at the back of the hole or groove. Due to the decrease of temperature and pressure, the merged materials cannot fully meet. Fusion produces a weld line in the plastic product, which not only affects the appearance of the product but also reduces the strength of the product at the welded part; if the weld line appears in a part with a small cross-section of the plastic product, the part is easily broken ;3. Due to thermal expansion and contraction, the thicker part of the plastic product will produce sink marks or hollow air bubbles, which will affect the appearance and strength of the product; 4. On the plastic product, during the process of injecting materials, separation The farther the sprue is, the smaller the injection pressure transmitted by the injection molding machine will be, which will cause a pressure difference in the cavity of the injection mold product, and the plastic product will cause various defects (dimensional variation and plastic product deformation, etc.) due to the pressure difference; 5 1. Poor exhaust of the injection mold will cause trapped air or burnt phenomenon on the plastic product, which will affect the appearance and strength of the product;

During the production of injection molding products, one of the above-mentioned problems may occur in different processes, or several of the above-mentioned problems may occur at the same time, and they can only be processed after the injection molding products are demoulded. The production cost is high, and even some problems cannot be solved. Solved in the follow-up process, resulting in product defects.
