[0002] Wear-resistant plates for molds are key functional components in mold systems, primarily used to reduce friction and wear on moving parts, thereby improving mold precision and service life.

[0003] In the prior art, the wear-resistant plate of the mold is often embedded with graphite blocks to increase the lubrication effect. When installing the graphite blocks, a small rubber hammer is usually used to hammer the graphite blocks into the groove opened on the top of the wear-resistant plate. When the graphite blocks are damaged, they are difficult to remove. Summary of the Invention

[0004] The purpose of this invention is to provide a fatigue-resistant mold wear plate with stress dispersion grooves, in order to solve the problem mentioned in the background art that when installing graphite blocks, rubber hammers are mostly used to hammer the graphite blocks into the grooves opened on the top of the wear plate, and the graphite blocks are difficult to disassemble when they are damaged.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a wear-resistant plate mechanism, comprising a mold wear-resistant plate, a stress dispersion groove, a placement groove, a trapezoidal protrusion, an internal thread groove, and a movable opening. An installation mechanism is provided inside the wear-resistant plate mechanism, comprising a threaded rod, a mounting bracket, an installation groove, a recess, a moving groove, a limiting slide groove, a sliding block, and a limiting block. A graphite block mechanism is also provided inside the installation mechanism, comprising an installation block, a slot, and a lubricating graphite block.

[0006] In a preferred embodiment, the top of the mold wear plate is provided with a stress dispersion groove, and the inside of the mold wear plate is provided with a placement groove, the inner wall of which is fixedly connected to one side of the trapezoidal protrusion.

[0007] In a preferred embodiment, the bottom of the placement groove is provided with an internal thread groove, and the bottom of the internal thread groove is provided with a movable opening.

[0008] In a preferred embodiment, the inner wall of the internal thread groove is threadedly connected to the outer wall of the threaded rod, the top outer wall of the threaded rod is rotatably connected to the bottom inner wall of the mounting bracket via a bearing, and the outer wall of the threaded rod is movably connected to the inner wall of the movable opening.

[0009] In a preferred embodiment, the mounting frame has an internal mounting groove, the outer wall of the mounting frame has a recess, and the inner wall of the recess is movably connected to the outer wall of the trapezoidal protrusion. The inner wall of the mounting groove has a movable groove.

[0010] In a preferred embodiment, the inner wall of the movable groove communicates with the inner wall of the groove, a limiting groove is provided at the top of the movable groove, and a cross groove is provided at the bottom of the threaded rod.

[0011] In a preferred embodiment, the inner wall of the movable groove is movably connected to the outer wall of the sliding block, the top of the sliding block is fixedly connected to the bottom of the limiting block, the outer wall of the limiting block is movably connected to the inner wall of the limiting groove, and the sliding block has an arc-shaped surface on the side near the groove.

[0012] In a preferred embodiment, the inner wall of the mounting groove is movably connected to the outer wall of the mounting block, the outer wall of the mounting block is provided with a slot, and the inner wall of the slot is movably connected to one side of the outer wall of the limiting block. The top of the mounting block is fixedly connected to the bottom of the lubricating graphite block, and the outer wall of the lubricating graphite block is movably connected to the inner wall of the placement groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when it is necessary to replace the lubricating graphite block, a tool is used to rotate the threaded rod in the opposite direction, causing the threaded rod to move upward through the internal thread groove, thereby driving the mounting bracket to move upward. The lubricating graphite block can then be removed and disassembled by pushing it out through the mounting bracket. During installation, a tool is used to rotate the threaded rod in the forward direction, causing the mounting bracket to move downward. At the same time, the lubricating graphite block is squeezed by the inclined surface of the trapezoidal protrusion and the arc surface of the sliding block as the mounting bracket moves. As the mounting bracket moves, the squeezing force on the sliding block increases, thereby squeezing the sliding block into the inside of the slot. At the same time, the limiting block moves inside the limiting groove, thereby stabilizing the lubricating graphite block and facilitating its removal and replacement.

[0015] In this invention, as the mounting bracket moves, the inclined surface of the trapezoidal protrusion presses against the arc-shaped surface of the sliding block. As the mounting bracket moves, the pressure on the sliding block increases, thus forcing the sliding block into the slot. Simultaneously, the limiting block moves within the limiting groove, thereby stabilizing the lubricating graphite block. By allowing the sliding block to enter the slot, the stability of the lubricating graphite block after installation is increased, reducing the possibility of the lubricating graphite block falling off.

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] Please see Figures 1-5 This utility model provides a technical solution comprising: a wear-resistant plate mechanism 1, which includes a mold wear-resistant plate 101, a stress dispersion groove 102, a placement groove 103, a trapezoidal protrusion 104, an internal thread groove 105, and a movable opening 106; an installation mechanism 2 is provided inside the wear-resistant plate mechanism 1, which includes a threaded rod 201, a mounting bracket 202, an installation groove 203, a groove 204, a moving groove 205, a limiting slide groove 206, a sliding block 207, and a limiting block 208; and a graphite block mechanism 3 is provided inside the installation mechanism 2, which includes an installation block 301, a slot 302, and a lubricating graphite block 303.

[0025] In one embodiment, the top of the mold wear plate 101 is provided with a stress dispersion groove 102, and the inside of the mold wear plate 101 is provided with a placement groove 103, the inner wall of the placement groove 103 being fixedly connected to one side of the trapezoidal protrusion 104.

[0026] Specifically, the stress dispersion groove 102 reduces fatigue cracks, fractures, or premature wear caused by stress concentration.

[0027] In one embodiment, the bottom of the placement groove 103 is provided with an internal thread groove 105, and the bottom of the internal thread groove 105 is provided with a movable opening 106.

[0028] Specifically, the movable port 106 facilitates the storage and stabilization of the threaded rod 201.

[0029] In one embodiment, the inner wall of the internal thread groove 105 is threadedly connected to the outer wall of the threaded rod 201, the top outer wall of the threaded rod 201 is rotatably connected to the bottom inner wall of the mounting bracket 202 via a bearing, and the outer wall of the threaded rod 201 is movably connected to the inner wall of the movable port 106.

[0030] Specifically: Use a tool to rotate the threaded rod 201 in the opposite direction, so that the threaded rod 201 moves upward through the internal thread groove 105.

[0031] In one embodiment, the mounting bracket 202 has an internal mounting groove 203, and the outer wall of the mounting bracket 202 has a groove 204. The inner wall of the groove 204 is movably connected to the outer wall of the trapezoidal protrusion 104, and the inner wall of the mounting groove 203 has a movable groove 205.

[0032] Specifically, the trapezoidal protrusion 104 facilitates the compression of the sliding block 207, allowing it to enter the slot 302, thereby increasing the stability of the lubricating graphite block 303 after installation and reducing the possibility of the lubricating graphite block 303 falling off.

[0033] In one embodiment, the inner wall of the movable groove 205 communicates with the inner wall of the groove 204, a limiting slide groove 206 is provided at the top of the movable groove 205, and a cross groove is provided at the bottom of the threaded rod 201.

[0034] Specifically: When it is necessary to replace the lubricating graphite block 303, use a tool to rotate the threaded rod 201 in the opposite direction, so that the threaded rod 201 moves upward through the internal thread groove 105, thereby driving the mounting bracket 202 to move upward, and the lubricating graphite block 303 can be pushed out and removed through the mounting bracket 202.

[0035] In one embodiment, the inner wall of the moving groove 205 is movably connected to the outer wall of the sliding block 207, the top of the sliding block 207 is fixedly connected to the bottom of the limiting block 208, the outer wall of the limiting block 208 is movably connected to the inner wall of the limiting groove 206, and the side of the sliding block 207 near the groove 204 is provided with an arc-shaped surface.

[0036] Specifically: as the mounting bracket 202 moves, the inclined surface of the trapezoidal protrusion 104 presses against the arc-shaped surface of the sliding block 207, and the pressure on the sliding block 207 increases as the mounting bracket 202 moves.

[0037] In one embodiment, the inner wall of the mounting groove 203 is movably connected to the outer wall of the mounting block 301, the outer wall of the mounting block 301 is provided with a slot 302, and the inner wall of the slot 302 is movably connected to one side of the outer wall of the limiting block 208. The top of the mounting block 301 is fixedly connected to the bottom of the lubricating graphite block 303, and the outer wall of the lubricating graphite block 303 is movably connected to the inner wall of the placement groove 103.

[0038] Specifically: the sliding block 207 is pressed into the inside of the slot 302, while the limiting block 208 moves inside the limiting slide groove 206, thereby stabilizing and lubricating the graphite block 303.

[0039] Working principle: Using a tool, rotate the threaded rod 201 in the reverse direction, causing it to move upward through the internal thread groove 105. This, in turn, drives the mounting bracket 202 upward. The mounting bracket 202 prevents the arc-shaped surface of the sliding block 207 from contacting the inclined surface of the trapezoidal protrusion 104. Place the mounting block 301 into the mounting groove 203, ensuring that the position of the slot 302 corresponds to the position of the sliding block 207. Then, using a tool, rotate the threaded rod 201 in the forward direction, causing the mounting bracket 202 to move downward. Simultaneously, this compresses the lubricating graphite block 303, causing the mounting block 301 to move downward along with the mounting bracket 202. 2. As the mounting bracket 202 moves downward, the inclined surface of the trapezoidal protrusion 104 presses against the arc-shaped surface of the sliding block 207. As the mounting bracket 202 moves, the pressure on the sliding block 207 increases, thereby pressing the sliding block 207 into the slot 302. At the same time, the limiting block 208 moves inside the limiting groove 206, thereby stabilizing the lubricating graphite block 303. When the lubricating graphite block 303 needs to be replaced, the threaded rod 201 is rotated in the opposite direction using a tool, and the lubricating graphite block 303 is pushed out and removed through the mounting bracket 202.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
