Description

A metal mold structure

technical field

The utility model belongs to the technical field of metal molds, in particular to a metal mold structure.

Background technique

Mold is an important fixture of modern advanced manufacturing, and it is widely used in machinery manufacturing, electronics, automobiles, daily necessities and other fields. The mold usually includes a movable mold and a fixed mold. Cavities are respectively set on the movable mold and the fixed mold. The molten material is filled into the cavity, and then cooled to form a corresponding product according to the setting of the cavity. After the mold is cooled, separate the movable mold from the fixed mold, and then take out the product. If the product is taken out manually, because the product is in the cavity of the movable mold, tools are usually needed to remove it, which increases the working time and reduces the work efficiency, and the product is easy to be damaged due to careless operation.

Contents of the invention

The technical problem to be solved by the utility model is to provide a metal mold structure, which ejects the product during the mold opening process, automates the operation, and improves the efficiency.

In order to solve the above technical problems, the utility model takes the following technical solutions:

A metal mold structure, comprising a mold frame, the bottom surface of the mold frame is provided with a fixed mold, the fixed mold is provided with a fixed mold cavity, and the top of the mold frame is provided with a lifting cylinder, the piston shaft of the lifting cylinder passes through the mold frame and is connected with a A movable mold, a movable mold cavity is provided on the movable mold, and it is characterized in that a socket is provided in the movable mold, and a push rod is movable in the socket, and a spring is fixedly set on the push rod, and the lower end of the spring is installed on the On the inner wall of the socket, the top of the mold frame is provided with an insertion rod facing the ejector rod;

When the lifting cylinder drives the movable mold to rise to the top of the mold frame, the inserting rod is inserted into the jack and withstands the ejector rod, so that the ejector rod extends to the movable model cavity.

The side wall of the push rod is provided with a clamping block for clamping the spring.

The movable mold is provided with a positioning guide block located around the socket.

The positioning guide block is inclined and inclined towards the direction of the socket.

The movable mold is provided with a guide column, and the fixed mold is provided with a guide sleeve, and the guide column is inserted into the guide sleeve.

The lower end of the insertion rod has a truncated cone shape.

The utility model utilizes the plunger to eject the products in the cavity of the movable mold during the process of moving the movable mold upwards to open the mold, thereby automatically operating and improving the efficiency.

Description of drawings

Accompanying drawing 1 is the utility model sectional structure schematic diagram.

detailed description

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.

As shown in accompanying drawing 1, the utility model discloses a kind of metal mold structure, comprises mold frame 1, and this mold frame 1 bottom surface is provided with fixed mold 2, and fixed mold 2 is provided with fixed mold cavity 3, and mold frame 1 top is provided with There is a lifting cylinder 11, the piston shaft of the lifting cylinder 11 passes through the mold frame 1 and is equipped with a moving mold 12, the moving mold 12 is provided with a moving mold cavity 4, and the moving mold 12 is provided with a jack 5, the plug A ejector rod 6 is movable in the hole 5, and a spring 8 is fixedly set on the ejector rod 6. The lower end of the spring 8 is installed on the inner wall of the jack 5, and the top of the mold frame 1 is provided with an insert rod 10 facing the ejector rod 6; When the cylinder 11 drives the movable mold 12 to rise to the top of the mold frame 1, the insert rod 10 is inserted into the socket 5 and withstands the ejector rod 6, so that the ejector rod 6 extends to the movable mold cavity 4. When the movable mold and the fixed mold are closed, the insert rod Back out of the jack with the ejector pin fully inside the jack. The plunger is fixedly mounted on the mold frame and remains motionless.

The side wall of the push rod 6 is provided with a clamping block 7 for clamping the spring 8, which facilitates the installation of the spring.

The movable mold 12 is provided with a positioning guide block 9 located around the socket 5 . The positioning guide block 9 is inclined and inclined towards the direction of the insertion hole. Through the positioning guide block, it is ensured that during the upward movement of the movable mold, the inserting rod can accurately enter the socket. The lower end of the insertion rod is provided with a truncated cone shape.

The movable mold 12 is provided with a guide column 13, and the fixed mold 2 is provided with a guide sleeve 14, and the guide column is inserted into the guide sleeve. When the fixed mold and the movable mold are closed, the movable mold and the fixed mold can be accurately aligned.

In the utility model, the lifting cylinder drives the moving mold to rise or fall. When the movable mold and the fixed mold were closed, the plunger had not been inserted into the jack yet. When the mold needs to be opened after the product is formed, the lifting cylinder drives the movable mold to move upwards. With the continuous upward movement of the movable mold, the insertion rod is inserted into the socket, and then withstands the ejector rod, so that the ejector rod moves toward the movable mold cavity, and finally the The product in the movable mold cavity is ejected.

In addition, for the selection of the lifting cylinder, there is no specific model, as long as the existing cylinder can realize the lifting function.

In addition, the plunger is also made of high-temperature-resistant materials to ensure that it can withstand the high-temperature environment of the mold without being easily damaged.

It should be noted that the above description is not a limitation of the present utility model, and any obvious replacements are within the protection scope of the present utility model without departing from the inventive concept of the present utility model.
