Technical Field
[0001] This utility model relates to the field of machining mold technology, specifically a high-precision mold for a squaring machine. Background Technology
[0002] The core function of the square forming machine mold is to efficiently form square parts. Its design is suitable for both injection molding and powder metallurgy processes. In the injection molding field, the mold achieves high-precision injection molding of thin-walled square shell products (such as electronic device housings) through a hot runner system and a multi-directional core pulling mechanism. The ejection system uses a combination of push plates and ejector pins to complete non-destructive demolding. In the powder metallurgy scenario, the mold adopts a segmented inner core and sleeve fixing structure.
[0003] The existing technology has the following shortcomings: When using the existing square-forming machine mold, due to the large number of internal grooves, manual demolding is required after forming, which is time-consuming and labor-intensive. In addition, the sheet forming is completed by unidirectional pressure, which cannot complete the forming of rectangular structures. Therefore, it has poor versatility and low degree of automation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a high-precision mold for a squaring machine, which solves the problems of the inability to automatically demold and the inability to form rectangular structures due to the single pressure surface.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision mold for a square-making machine, comprising a main body, a pad, and a side support, wherein the pad is disposed on the top of the main body and the side support is disposed on the upper end of the main body.
[0006] The upper end of the pad is provided with a linkage extrusion block, the upper part of the main body of the equipment is provided with a vertical pressure plate, and the inner side of the pad is provided with a limit groove.
[0007] The vertical pressure plate also includes a central pressure block and side pressure blocks. The central pressure block is fixedly connected to the bottom center of the vertical pressure plate, and two sets of side pressure blocks are provided and welded to both sides of the bottom of the vertical pressure plate.
[0008] As a preferred technical solution of this utility model, the central pressure block has a rectangular structure, and two sets of lateral grooves are provided at the top of the block adjacent to the vertical pressure plate.
[0009] As a preferred embodiment of this utility model, the side of the side pressure block near the two sides of the vertical pressure plate is perpendicular to its bottom, while the side near the middle pressure block is inclined.
[0010] As a preferred technical solution of this utility model, the linkage extrusion block further includes a slider, a connecting rod, a spring, and a sealing protrusion. The slider is welded to the bottom of the linkage extrusion block, and the connecting rod is inserted into the side end of the linkage extrusion block.
[0011] As a preferred technical solution of this utility model, the spring is sleeved around the connecting rod and is located between the side bracket and the outer end of the connecting rod. The sealing protrusion and the linkage extrusion block are integrally die-cast and have a rectangular structure.
[0012] As a preferred embodiment of this utility model, the connecting rod passes through the side bracket, and a disc-shaped structure is provided at its end away from the linkage extrusion block, and the diameter of the disc-shaped structure is larger than that of the spring.
[0013] As a preferred technical solution of this utility model, the linkage extrusion block has an inclined structure facing the side support, and it matches the inclined surface of the side pressure block.
[0014] Compared with the prior art, this utility model provides a high-precision mold for a squaring machine, which has the following characteristics:
[0015] Beneficial effects:
[0016] A high-precision mold for a squaring machine is provided, comprising a linked extrusion block, a slider, a connecting rod, a spring, and a vertical pressure plate. In use, the operator places the material to be squared horizontally on the top of the linked extrusion block, and then connects the top of the vertical pressure plate to an external hydraulic cylinder. The cylinder controls the vertical pressure plate to press down, and the central pressure block presses the material into the rectangular groove between the two linked extrusion blocks. Simultaneously, the side pressure blocks on both sides of the vertical pressure plate move downwards and contact the outer inclined surface of the linked extrusion block. Through continuous pressure from the vertical pressure plate, the inclined surfaces of the side pressure blocks press the linked extrusion block towards the center of the pad, the connecting rod is pulled, causing the spring to contract, and the slider moves in the limiting groove until the two linked extrusion blocks contact each other. The sealing protrusions near the top of the blocks press the material from both ends and make it fit against the grooves on both sides of the upper end of the central pressure block. At this point, the material is fully formed. When the hydraulic cylinder moves the vertical pressure plate upwards to reset, the spring rebounds, the connecting rod moves the linked extrusion block to reset synchronously, and the central pressure block carries the material out.
[0017] With the above settings and process, when the mold is used, the linkage extrusion block can be quickly reset after completing one molding operation through the cooperation of the spring and the connecting rod. Through the cooperation of the middle pressure block and the side pressure block, the material can be molded in one go. When the vertical pressure plate moves up and resets, it can also drive the molded material to reset, thus making the squaring machine highly efficient and able to automatically demold, improving the degree of automation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] In this embodiment: a high-precision mold for a square-making machine includes a main body 1, a pad 2, and a side bracket 3. The pad 2 is disposed on the top of the main body 1, and the side bracket 3 is disposed on the upper end of the main body 1.
[0025] A linkage extrusion block 4 is provided on the upper end of the pad 2, a vertical pressure plate 5 is provided on the upper part of the main body 1, and a limit groove 6 is provided on the inner side of the pad 2.
[0026] The vertical pressure plate 5 also includes a central pressure block 501 and side pressure blocks 502. The central pressure block 501 is fixedly connected to the bottom of the middle part of the vertical pressure plate 5, and two sets of side pressure blocks 502 are provided and welded to both sides of the bottom of the vertical pressure plate 5.
[0027] In this embodiment, the central pressure block 501 has a rectangular structure, and two sets of lateral grooves are provided at the position of its top adjacent to the vertical pressure plate 5; the side of the side pressure block 502 near the two sides of the vertical pressure plate 5 is perpendicular to its bottom, while the side near the central pressure block 501 is inclined.
[0028] Specifically, such as Figure 1 and Figure 3As shown, a lateral groove is provided at the top position of the middle pressure block 501 near the vertical pressure plate 5 to bear the lateral pressure of the sealing protrusion 404, thereby bending the top of the processed material and connecting the material with the middle pressure block 501.
[0029] In this embodiment, the linkage extrusion block 4 further includes a slider 401, a connecting rod 402, a spring 403, and a sealing protrusion 404. The slider 401 is welded to the bottom of the linkage extrusion block 4, and the connecting rod 402 is inserted into the side end of the linkage extrusion block 4. The spring 403 is sleeved around the connecting rod 402 and is located between the side support 3 and the outer end of the connecting rod 402. The sealing protrusion 404 is integrally die-cast with the linkage extrusion block 4 and has a rectangular structure. The connecting rod 402 passes through the side support 3, and a disc-shaped structure is provided at the end away from the linkage extrusion block 4, and the diameter of the disc-shaped structure is larger than that of the spring 403.
[0030] Specifically, such as Figure 2 and Figure 4 As shown, the disc-shaped structure at the end of the connecting rod 402 can limit the position of the spring 403 to the side bracket 3 and the outside, and enable the spring 403 to contract when the connecting rod 402 moves.
[0031] In this embodiment, the linkage extrusion block 4 has an inclined structure facing the side support 3, and it matches the inclined surface of the side pressure block 502.
[0032] The working principle and usage process of this utility model are as follows: When using this mold structure, the operator places the material to be squared horizontally on the upper end of the linkage extrusion block 4, and then connects the top of the vertical pressure plate 5 to the external hydraulic cylinder. The cylinder controls the vertical pressure plate 5 to press down, and the middle pressure block 501 presses the material into the rectangular groove between the two linkage extrusion blocks 4. At the same time, the side pressure blocks 502 on both sides of the vertical pressure plate 5 move downward and contact the outer inclined surface of the linkage extrusion block 4 through the inclined surface. Through the continuous pressure of the vertical pressure plate 5, the inclined surface of the side pressure block 502 presses the linkage extrusion block 4 towards the middle of the pad 2. The connecting rod 402 is pulled and causes the spring 403 to contract, while the slider 401 moves in the limiting groove 6 until the two linkage extrusion blocks 4 on both sides contact each other. The sealing protrusion 404 near the upper end of the block will squeeze the two ends of the material from both sides and make it fit against the grooves on both sides of the upper end of the middle pressure block 501. At this point, the material is fully formed. When the hydraulic cylinder moves the vertical pressure plate 5 upward to reset, the spring 403 rebounds, the connecting rod 402 drives the linkage extrusion block 4 to reset synchronously, and the middle pressure block 501 carries the material out.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
