Problems solved by technology

For such as figure 1 As shown in the automotive motor products, since the metal insert 1 is provided in the motor casing, and the outer wall of the metal insert 1 is provided with pins 101; before injection molding, the metal insert 1 must be accurately positioned. Make the pin 101 align correctly with the corresponding slider; otherwise, the slider may collide with the pin 101 during feeding and damage the pin 101, resulting in scrap
For this kind of products with special structure, there is no suitable solution to ensure the quality of injection molding and the convenience of operation at the same time.

Embodiment 1

[0050] See attached figure 2 , an injection mold mainly used for the injection molding operation of a motor casing with a metal insert 1, which includes an axial positioning assembly 2, a pre-positioning assembly 3, a final positioning assembly 4 and a mold clamping assembly arranged on a workbench . The axial positioning component 2 can be used to install the metal insert 1 and realize the axial positioning of the metal insert 1 . After the axial positioning component 2 realizes the axial positioning of the metal insert 1, the pre-positioning component 3 can realize the circumferential pre-positioning of the metal insert 1, so that the installation angle of the metal insert 1 on the axial positioning component 2 can be determined . After the pre-positioning component 3 realizes the circumferential pre-positioning of the metal insert 1 , the final positioning component 4 can form an insertion fit with the pin 101 on the metal insert 1 , and realize precise positioning of th...

Embodiment 2

[0066] See attached Figure 8 , a method of injection molding a motor housing with a metal insert, comprising the steps of:

[0067] S1. Preparation, setting predetermined positioning points on the outer wall of the metal insert 1 . Before actually starting the injection molding operation, preparatory work should be carried out; considering the ring structure of the metal insert 1, in order to facilitate the determination of the installation angle of the metal insert 1, a predetermined position can be set on the outer wall of the metal insert 1. In conjunction with the accompanying drawings, the predetermined location point can be a positioning notch 102; in actual operation, the positioning notch 102 can form a snap-fit ​​fit with the positioning protrusion 3221 on the positioning fitting block 322, thereby realizing predetermined positioning of the metal insert 1. bit.

[0068] S2, axial positioning. After the above-mentioned preparatory work is completed, the first drive...

Abstract

The invention discloses a motor housing injection molding method with a metal insert and an injection mold of the motor housing injection molding method, and relates to the technical field of injection molds. The motor housing injection molding method with the metal insert comprises the steps of preparing, axial locating, pre-locating, final locating, mold compounding, injection molding and the like. The injection mold comprises an axial locating assembly, a pre-locating assembly, a final locating assembly and a mold compounding assembly. The pre-locating assembly comprises a first drive part,the first drive part is connected with a pre-locating combined sliding block, and a pre-locating structure is formed on the pre-locating combined sliding block. The final locating assembly comprisesa first combined sliding block, the first combined sliding block is connected with a second drive part, and an inserted cooperation part is arranged on the first combined sliding block. By means of the motor housing injection molding method with the metal insert and the injection mold of the motor housing injection molding method, operation is convenient, the injection molding quality and production efficiency can be improved easily, and the product rejection rate can be reduced.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection molding method for a motor casing with a metal insert and an injection mold thereof. Background technique [0002] Injection molds usually include two parts: a movable mold and a fixed mold, and the mold core is the core part of the injection molded finished product. The general process of injection molding using an injection mold includes six stages: clamping, injection, pressure holding, cooling, demoulding, and finished product removal. [0003] Existing plastic injection mold usually comprises parts such as slide block, inclined top block, inclined top connecting block, slide block guide slide, combined drag hook and oil cylinder. For such as figure 1 As shown in the automotive motor products, since the metal insert 1 is provided in the motor casing, and the outer wall of the metal insert 1 is provided with pins 101; before injection molding, the metal ...
