Description

A switch part mold

technical field

The utility model relates to a mold, in particular to a switch part mold.

Background technique

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 shape an object. 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. Known as the "Mother of Industry".

Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing.

In the production process of switch parts, there is no special mold, which cannot realize rapid continuous and mass production.

Utility model content

(1) Technical problems to be solved

In order to overcome the disadvantage that there is no special mold in the current production process of switch parts, the utility model cannot realize rapid continuous and batch production. The technical problem to be solved by the utility model is to provide a switch part mold.

(2) Technical solution

In order to solve the above-mentioned technical problems, the utility model provides such a mold for switch parts, which includes a lower mold body, a fan-shaped bump, a key-shaped bump, an upper mold body and a round bump, and there are four annular arrays on the lower mold body. Sector-shaped protrusions, a word groove is arranged between the four sector-shaped protrusions, and a key-shaped protrusion is provided in the middle of the lower mold body. The key-shaped protrusion is located in the middle of the four sector-shaped protrusions. Between the key-shaped protrusions and the four An annular groove is arranged between the fan-shaped protrusions, a circular groove is arranged on the upper mold body, a cross groove is arranged in the circular groove, and a circular bump is arranged in the middle of the cross groove, and the lower mold body and the upper mold body With the use of.

Working principle: There are four fan-shaped bumps in the ring array on the lower mold body, and there is a word groove between the four fan-shaped bumps. In the middle of the block, there is an annular groove between the key-shaped bump and the four fan-shaped bumps, a circular groove is arranged on the upper mold body, a cross groove is arranged in the circular groove, and a cross groove is arranged in the middle of the cross groove. There are round bumps, and the lower mold body is used in conjunction with the upper mold body. When working, the lower mold body and the upper mold body are installed on the injection molding equipment, and the injection molding equipment is used for injection molding, so that the material can be injection molded at one time.

(3) Beneficial effect

The utility model provides a mold for switch parts, which adopts a variety of grooves and bump structures, and uses stamping equipment to stamp and form materials at one time, thereby realizing rapid continuous and batch production and improving work efficiency. The progress of the work is accelerated, and the formed switch parts have super high support strength, quality, safety and reliability.
