Positioning process of double-cavity mold

Abstract

The invention provides a positioning process of a double-cavity mold. The positioning process comprises the steps of mutually matching a moving mold and a fixed mold through a guide assembly; arranging a sprue insert at the central position of the fixed mold through a positioning pin; arranging a feed inlet insert at the central position of the moving mold through a positioning pin; respectively arranging two fixed mold cores on two sides of the sprue insert; and respectively arranging two moving mold cores on two sides of the feed inlet insert. Due to the adoption of the double-cavity design,a plurality of products can be produced through one-step molding, so that the production performance of an injection molding machine is fully utilized, the cost of time and labor is saved, and the production efficiency is improved; and the adoption of an intermediate positioning structure can not only accurately position the balance of the moving mold and the fixed mold between a left cavity anda right cavity or between a front cavity and a rear cavity or between an upper cavity and a lower cavity, but also advantageously maintain the single cavity of the mold.

Description

technical field [0001] The invention relates to a positioning process, in particular to a positioning process for a double-cavity mold. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. Both the movable mold and the fixed mold form a fixed cavity. Size cann...

AI Technical Summary

Problems solved by technology

[0004] At present, the mold is an important production tool. The slider mechanism is often used in the mold to form complex parts. The slider must move back and forth in the mold to meet the molding requirements and ensure the molding quality. The forward and backward positions of the slider The determination of the position is very important, and the positioning must be accurate and reliable. Generally, the forward position of the slider is used to form the product. The position and direction are determined by the product. The traditional forward and backward movement has certain limitations and cannot meet the requirements of some products. Need, and the positioning is not precise

[0005] At present, the molds for product molding in the mold industry adopt the production method of one mold and one cavity, resulting in only one product for each molding, low production efficiency, high time and labor costs, and the production performance of the injection molding machine is not fully utilized.

[0006] At present, some product molding molds in the mold industry adopt a multi-cavity production method, but there is no positioning structure or an intermediate positioning structure, but two-side positioning, which leads to inaccurate positioning and reduces the product yield.
