[0001] The utility model relates to the technical field of die-casting molds, and particularly relates to a balanced locking structure of a die-casting mold. Background Art
[0002] There are various types of molds with different structures, and various sliders have become common structures in die-casting molds. However, when there is a large single-sided slider in the mold structure and the opposite side is a flat surface without any obstruction, due to the thermal expansion factor of the mold, the shape of the slider becomes larger as the temperature rises, and the force on the slider locking part increases, causing the fixed mold core and the moving mold core to shift, resulting in product deviation and inability to meet its dimensional requirements. Therefore, a locking structure is needed to solve this problem. Content of the Utility Model
[0003] The utility model provides a balanced locking structure of a die-casting mold, with a simple structure, which can solve the problem that the fixed mold core and the moving mold core displace due to the lack of a locking structure in the existing die-casting mold with a large single-sided slider.
[0004] To achieve the above object, the utility model provides the following technical solution: a balanced locking structure of a die-casting mold, including: a fixed mold frame and a moving mold frame arranged up and down, a mutually matching fixed mold core and a moving mold core are arranged between the fixed mold frame and the moving mold frame, a slider core is arranged on one side of the fixed mold core and the moving mold core, a slider seat located between the fixed mold frame and the moving mold frame is connected to one side of the slider core, a balanced locking block is arranged on the other side of the fixed mold core, the lower end of the balanced locking block is connected to the moving mold frame, one side of the balanced locking block abuts against the side wall of the fixed mold core, and the other side of the balanced locking block abuts against the fixed mold frame. By arranging a balanced locking block on the other side of the slider core, the balanced locking block can lock the fixed mold core and interact with the locking of the slider seat to prevent the fixed mold core and the moving mold core from moving.
[0005] Preferably, a first locking friction block is installed between the balanced locking block and the fixed mold core, and a second locking friction block is installed between the slider seat and the fixed mold frame. The first locking friction block and the second locking friction block can facilitate smooth locking during mold opening and closing, and can also be conveniently replaced after wear.
[0006] Preferably, the inclination angles of the first locking friction block and the second locking friction block are the same, so that the forces received by the slider seat and the balanced locking block are the same, and balance can be achieved.
[0007] Preferably, the balanced locking block includes a locking block main body arranged on the upper side of the moving mold frame and a positioning block arranged at the lower end of the locking block main body. The positioning block is embedded in the moving mold frame, and the connection strength between the balanced locking block and the moving mold frame can be improved through the positioning block.
[0008] Preferably, a connecting screw vertically passing through the moving die frame is installed at the lower end of the positioning block. The upper end of the connecting screw is fixedly connected to the positioning block, which is convenient and reliable for installation.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0017] As Figures 1-3As shown in the figure, the present utility model aims to solve the problem that in the existing die-casting mold with a large unilateral slider, there is no locking structure, resulting in the displacement of the fixed die core and the moving die core. The following technical solutions are provided: A balanced locking structure for a die-casting mold, including: a fixed die frame 2 and a moving die frame 1 arranged vertically. A mutually matching fixed die core 4 and a moving die core 8 are arranged between the fixed die frame 2 and the moving die frame 1. A slider core 5 is arranged on one side of the fixed die core 4 and the moving die core 8. One side of the slider core 5 is connected to a slider seat 6 located between the fixed die frame 2 and the moving die frame 1. On the other side of the fixed die core 4, there is a balanced locking block 3. The lower end of the balanced locking block 3 is connected to the moving die frame 1. One side of the balanced locking block 3 abuts against the side wall of the fixed die core 4, and the other side of the balanced locking block 3 abuts against the fixed die frame 2. By arranging a balanced locking block 3 on the other side of the slider core 5, the balanced locking block 3 can lock the fixed die core 4 and interact with the locking of the slider seat 6 to prevent the fixed die core 4 and the moving die core 8 from moving.
[0018] Specifically, the fixed die frame 2 and the fixed die core 4 are fixed. When the mold is opened, the moving die core 8, the moving die frame 1, the slider core 5 and the slider seat 6 can move together and separate from the fixed die frame 2 and the fixed die core 4, as Figure 2 shown. When the mold is closed, the balanced locking block 3 can abut against both the fixed die frame 2 and the fixed die core 4 simultaneously.
[0019] In the closed mold state, a mold cavity is formed between the fixed die core 4, the moving die core 8 and the slider core 5, and molten aluminum can be injected for forming under high pressure.
[0020] In this embodiment, as Figure 1 shown, a first locking friction block 10 is installed between the balanced locking block 3 and the fixed die core 4, and a second locking friction block 7 is installed between the slider seat 6 and the fixed die frame 2. The first locking friction block 10 and the second locking friction block 7 can facilitate smooth locking during mold opening and closing, and can also be conveniently replaced after wear. At the same time, the inclined angles of the first locking friction block 10 and the second locking friction block 7 are the same, so that the forces received by the slider seat 6 and the balanced locking block 3 are the same, and balance can be achieved.
[0021] In this embodiment, as Figure 3 shown, the balanced locking block 3 includes a locking block main body 32 arranged on the upper side of the moving die frame 1 and a positioning block 31 arranged at the lower end of the locking block main body 32. The positioning block 31 is embedded in the moving die frame 1, and the connection strength between the balanced locking block 3 and the moving die frame 1 can be improved through the positioning block 31.
[0022] For the convenience of installing the balance locking block 3, a connecting screw 9 vertically passing through the moving die frame 1 is installed at the lower end of the positioning block 31. The upper end of the connecting screw 9 is fixedly connected to the positioning block 31, ensuring convenient and reliable installation.
