Description

Injection mold with multi-cavity assembly

Technical Field

The utility model relates to the technical field of injection molds, in particular to an injection mold with a multi-cavity assembly.

Background

Injection molds are well known as a tool for producing plastic articles; is also a tool for endowing plastic products with complete structure and precise dimensions. Injection molding is a process used in mass production of parts of complex shape. The method specifically comprises the steps of injecting heated and melted plastic into a die cavity under high pressure by an injection molding machine, cooling and solidifying to obtain a formed product, wherein the injection molding die is divided into a thermosetting plastic die and a thermoplastic plastic die according to the forming characteristics; the hot-pressing mold can be divided into three types of overflow, half overflow and non-overflow in a flash mode, and the injection mold can be divided into two types of cold runner mold and hot runner mold in a pouring system; the mold structure may be varied depending on the type and performance of the plastic, the shape and structure of the plastic product, the type of the injection machine, etc., but the basic structure is uniform. The mould mainly comprises a pouring system, a temperature regulating system, a forming part and a structural part.

The section of the runner is reduced at the position of the runner, which is close to a product die cavity, of the existing injection mold with the multi-cavity assembly, so that products and waste materials are convenient to separate, but the mode has the following defects:

1. the reduced flow cross-sectional area results in a reduced rate of plastic flow into the product mold cavity, thereby affecting the rate of product production.

2. After the cross-sectional area of the runner is reduced, the pressure of the injection molding machine needs to be increased, otherwise, the condition of underinjection easily occurs in the product die cavity, and waste products easily occur.
