Description

A kind of automobile connector product forming mold

technical field

The utility model relates to the technical field of molds, in particular to a molding mold for automobile connector products.

Background technique

Molds, various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, a mold is a tool used to make a shaped item. This tool is composed of various parts. Different molds are composed of different parts. The mold has a specific contour or cavity shape, and the application of the cavity shape can make the blank. To obtain the corresponding three-dimensional shape, the mold generally includes two parts, a movable mold and a fixed mold (or a punch and a concave mold), which can be separated and combined.

Injection mold is a tool for producing plastic products, and it is also a tool for imparting complete structure and precise dimensions to plastic products. Injection molding is a processing method used in mass production of certain parts with complex shapes. The injection molding machine injects high pressure into the mold cavity, and after cooling and solidifying, the molded product is obtained.

The plastic mold needs to be demolded and separated after injection molding. Different demolding structures are designed according to different products. Some use multiple inserts, and some have complex structures. According to the structural characteristics of the products, the designed demolding structures are also different. In addition to the complex structure, it is easy to damage the mold after demolding, which affects the life of the mold.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Referring to Figures 1 and 2, in an embodiment of the present utility model, an automobile connector product forming mold includes: a female template 1 and a male template 2, the lower end of the female template 1 is provided with an oblique pin 13, the oblique pin 13 is about Symmetrically arranged two groups, the oblique pin 13 is located on the sliding seat 23, and the oblique pin 13 includes a vertical part whose upper part is perpendicular to the sliding seat 23 and an inclined part whose lower part is inclined to the sliding seat 23; 22 degrees, the upper end of the female template 1 is connected to the upper fixing plate 11, the top of the upper fixing plate 11 is provided with a mold glue inlet 12, the sliding seat 23 is arranged on the male template 2, and the sliding seat 23 and the male template 2 Sliding connection, the sliding stroke of the sliding seat 23 is 15 mm, the sliding seat 23 is provided with an inclined surface that cooperates with the inclined pin 13, and a guide hole is provided below the sliding seat 23, and the guiding hole cooperates with the inclined pin 13, and the inclined surface The matching distance between the vertical part of the pin 13 and the guide hole is 26 mm, the lower part of the male template 2 is connected to the spacer plate 21, the lower part of the spacer plate 21 is connected to the lower fixing plate 22, and the female template 1 and the male template 2 are closed. The pin 13 is inserted into the guide hole, and the plastic melted by high temperature heating is injected from the mold injection hole 12 into the mold cavity after the female template 1 and the male template 2 are closed, and plastic injection molding is performed.

An opening and closing method of an injection mold is based on the inclined pin design, adding a sliding seat delay action, and splitting the mold through the inclined pins and the sliding seat that cooperate with the male template and the female template, and the specific steps include:

Include the following steps:

1), the corresponding mold structure matching the installation settings;

2) Carry out injection molding according to the injection molding process, close the female template and the male template, insert the oblique pin into the guide hole, and the matching distance between the vertical part of the oblique pin and the guide hole is 26 mm. Plastic is injected into the mold cavity after the female template and the male template are closed from the plastic injection hole of the mold, and plastic injection molding is performed;

3) After injection molding, move the male template backwards, the oblique pins are gradually separated from the guide holes, the sliding stroke of the sliding seat 23 is 15 mm/s, and the trajectory when the vertical part is detached is in a straight line, and the male template is in the back. During the moving distance of 0-26 mm, the sliding seat 23 does not move.

4) After the male template moves back by 26 mm, and then continues to move backward, the inclined part of the inclined pin will begin to leave the guide hole, and when the male template and the female template are separated by 26 mm, the inclined surface of the inclined The inclined surface of the seat is in a fit state;
