Mold with high-efficiency cooling water line

Abstract

A mold with a high-efficiency cooling water line belongs to the field of thermoplastic plastic molds. First, each layer of templates and inserts in the injection mold is provided with the water line according to the mechanism characteristics, the overall molding temperature of the mold is stabilized, and the molding parts are evenly cooled; second, U-shaped connecting grooves are utilized to connect cooling water wells, which not only simplifies the mold structure but also facilitates cleaning and maintenance of the mold water line; third, baffles are accurate in position by means of two-way hanging platforms of the baffles 23, the positional deviation is avoided, the water flow sectional area at the positions of the water line is identical, the cooling water flow speed is balanced, and the overall temperature of the inserts is stable. Through the implementation of the above three points, the stable molding of a deep cavity plastic product is achieved, and uniform cooling and constanttemperature of each part of the mold are ensured. The size and the quality of the plastic product are ensured, the mold space is effectively utilized, the mold cost is reduced, the production efficiency is improved, the mold life is prolonged, and the product defect rate is reduced.

Description

technical field [0001] The invention belongs to the field of molding molds for thermoplastic plastics, relates to a mold provided with an efficient cooling water channel, and is mainly applied to molding molds with deep cavity plastic products. Background technique [0002] Plastic products have the advantages of low cost and strong plasticity, and are widely used in the national economy. The plastic industry occupies an extremely important position in the world today. my country has become the world's largest producer of plastic products. In the face of fierce competition in the mold injection molding industry, the cost of mold and injection molding production is very important. If the cooling water channel in the mold is unreasonable, it will not only affect the life of the mold but also increase the cost of mold and injection molding production. The cooling water channel of the mold usually refers to the penetrating hole machined in the mold frame and insert of the plasti...

In the face of fierce competition in the mold injection molding industry, the cost of mold and injection molding production is very important. If the cooling water channel in the mold is unreasonable, it will not only affect the life of the mold but also increase the cost of mold and injection molding production

The cooling water channel of the mold usually refers to the penetrating hole machined in the mold frame and insert of the plastic mold, which circulates continuously through a certain medium (such as water, oil). The conventional method of setting the mold cooling system It is to set a straight-through waterway. According to the outer peripheral shape of the insert, a straight-through waterway parallel to the periphery of the insert is set. The intersecting waterways in the insert are connected, and there are water outlets and water inlets. The degree of cooling is different. When mass production, it will lead to long production cycle or uneven cooling, which will cause various product defects, increase costs and reduce production efficiency.
