Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a quick mold closing auxiliary device for die casting mold frame. Background Technology

[0002] Pressure casting, or die casting for short, is a highly efficient metal forming process that injects molten or semi-molten metal into a precision mold cavity under high speed and pressure, and then rapidly cools it under pressure to form the final shape. It is one of the essential basic processes in modern industry and is widely used in the automotive, aerospace, and electronic equipment fields. In the die casting production process, the rapid mold closing is a crucial and frequently performed step. However, in actual production operations, especially with medium and large molds or molds with complex structures, "the mold cannot be pressed into place in one go" is a common and thorny technical problem. This problem mainly manifests as follows: when the moving mold is close to the mold closing end point, it stops due to asymmetrical and local resistance and cannot be fully closed to the predetermined position. Sometimes, it is even necessary for the operator to repeatedly perform "jogging" mold closing operations or use external force to knock or pry it to barely get it into place. If the mold is not fully closed before injection, it will cause serious defects such as flash, thickness deviation, and insufficient filling in the casting, resulting in an increased scrap rate. Repeated jogging mold closing or machine shutdowns seriously disrupt the production cycle and reduce equipment utilization. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a simple, rationally designed, and easy-to-use quick mold closing auxiliary device for die casting mold frames. By applying pressure to the moving mold, the moving mold and the fixed mold are pressed together, thus avoiding serious defects and improving production quality.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: It includes a base, a top plate, a fixed mold, and a moving mold. A top plate is provided on the upper side of the base, and connecting columns are symmetrically fixed on both the left and right sides of the base, with the upper sides of the connecting columns connected to the top plate. A fixed mold is fixedly provided on the base, a moving mold is provided on the upper side of the fixed mold, and a moving mold frame is provided on the upper side of the moving mold. It also includes: a support frame, which has an inverted "U" shaped structure and is positioned between the top plate and the moving mold frame; cylinders are symmetrically fixed on the upper left and right sides of the top plate, with the driving end of the cylinder passing through the top plate and fixedly mounted on the support frame; and columns, which are... Four, arranged in a rectangular structure, are fixedly installed on the upper side of the moving mold frame, with the upper end of the column passing through the horizontal end of the support frame; two drive frames, arranged in a "U" shape, are symmetrically fixed on the left and right sides of the moving mold frame; two drive blocks are slidably installed in their respective drive frames, and the outer side of each drive block is hinged to a hinge member via a hinge shaft; two drive motors are fixedly installed on the outer wall of the vertical ends of the left and right sides of the support frame, and the output shaft of each drive motor passes through the vertical end of the support frame and is then inserted and fixed within the hinge member; With the above technical solution design, when the cylinder drives the support frame to move downward, so that the moving mold moves downward and closes to the fixed mold, the drive motors on both sides are started to rotate simultaneously, so that the hinge parts rotate, thereby driving the drive block to move within the drive frame, driving the drive frame to move the moving mold downward and close with the fixed mold.

[0005] As a further improvement of this utility model, a limiting plate is fixedly provided on the upper side of the column; Through the above technical solution design, the limiting plate limits the movement of the column.

[0006] As a further improvement of this utility model, a hydraulic push rod is fixedly provided in the middle of the upper side of the top plate, and a support rod is provided after the pushing end of the hydraulic push rod passes through the top plate. The support rod passes through the horizontal end of the support frame, and a pressing platform is provided at the bottom end of the support rod. Through the above technical solution design, the hydraulic push rod drives the support rod to move downward, so that the pressing table presses against the moving mold, thus strengthening the pressing of the moving mold.

[0007] As a further improvement of this utility model, a support block is fixedly provided on the rear side of the horizontal end of the support frame, a movable rod is fixedly provided on the bottom of the support block, a positioning tube is fixedly provided on the base, and the positioning tube is located on the rear side of the fixed mold, and the movable rod is movably inserted into the positioning tube. The above technical solution guides the movement of the support frame.

[0008] As a further improvement of this utility model, a guide platform is fixedly provided on the rear side of the moving mold frame, and the guide platform is movably sleeved on the moving rod. Through the above technical solution design, when the moving mold frame moves, the guide table moves on the movable rod to provide guidance.

[0009] The working principle of this utility model is as follows: The cylinder is activated, causing the support frame to move downwards, which in turn moves the moving mold frame and the moving mold downwards to fit against the fixed mold. The movement of the support frame drives the movable rod to move and insert into the positioning tube. Then, the drive motors on both sides are activated, causing the hinge to rotate, which in turn moves the drive block within the drive frame, driving the drive frame to move downwards and close with the fixed mold. The movement of the moving mold frame drives the guide table to move on the movable rod for guidance. The hydraulic push rod is activated, causing the pressing table to move downwards and press against the moving mold frame to reinforce the pressing of the moving mold. Conversely, after pressing is completed, the hydraulic push rod and the cylinder are activated to move the pressing table and the support frame upwards to disengage from the fixed mold.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The support frame and the moving mold frame are not directly connected. The driving block drives the driving frame to move the moving mold frame, so that the moving mold is pressed down into the fixed mold, thereby improving the die-casting quality of the casting. 2. During the pressing of the moving mold, the pressing table applies pressure to the moving mold frame to reinforce the pressing of the moving mold; 3. The sliding fit between the column and the support frame is used to strengthen the stability of the moving mold frame during movement. Attached Figure Description
