Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing, and in particular to a grinding device for mold manufacturing. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. In order to meet the precision requirements of the mold during manufacturing, the mold needs to be ground and polished.

[0003] A search revealed Chinese Patent Publication No. CN218697144U, which discloses a grinding device for mold processing. The device includes a support frame, an upper limiting plate fixedly connected to the upper part of the back of the support frame, a telescopic adjusting rod movably sleeved inside the upper limiting plate, a grinding machine mounted on the lower part of the telescopic adjusting rod, a lower connecting plate fixedly connected to the lower part of the support frame, and an auxiliary support plate fixedly connected to the middle of the lower connecting plate. This device facilitates clamping the mold by pressing the baffle mounted on the outside of the limiting plate against different inclined surfaces, increasing the stability of the mold clamping. However, in existing grinding devices for mold production, clamping the mold is cumbersome, time-consuming, and labor-intensive. Furthermore, it is even more difficult to clamp molds with irregular shapes or uneven surfaces, causing shaking during grinding and resulting in a decrease in grinding efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 — Figure 6As shown, a grinding device for mold production includes a worktable 101. A support frame 102 is bolted to one side of the worktable 101, and a mounting frame 103 is bolted to the support frame 102. A grinding mechanism is mounted on the mounting frame 103. The grinding mechanism includes a hydraulic cylinder 601, which is bolted to the top of the mounting frame 103. A power component 602 is bolted to the output end of the hydraulic cylinder 601. The power component 602 includes a dustproof housing and an electric motor. The electric motor is bolted inside the dustproof housing, and a grinding disc 603 is bolted to the output end of the electric motor. The grinding disc 603 can grind the top surface of the mold when it rotates. A rotating mechanism is mounted on the top of the worktable 101. The rotating mechanism includes a turntable 201, which is rotatably connected to the top of the worktable 101. A placement platform 202 is bolted to the top of the turntable 201. A spiral groove 203 is formed on the placement platform 202. A toggle component is mounted on the turntable 201. The worktable 101 is equipped with... A locking mechanism is provided to limit the rotation of the actuating component. A mounting mechanism is provided on the worktable 101. The mounting mechanism includes several guide components and a translation rod 403. The translation rod 403 is movably mounted on the guide components. A movable seat 404 is bolted to the translation rod 403. The movable seat 404 is slidably connected in the spiral groove 203 of the placement table 202. When the placement table 202 rotates, the spiral groove 203 enables several movable seats 404 to move synchronously to clamp and fix the side of the mold, which is convenient to use. A clamping mechanism is provided on the translation rod 403. The clamping mechanism includes a fixed seat 501. The fixed seat 501 is bolted to the top of the translation rod 403. A U-shaped guide rod 502 is bolted to the fixed seat 501. Two parallel movable rods 503 are slidably connected to the guide rod 502. A force balancing component is provided on the inner side of the movable rod 503. A clamping head 504 is bolted to one end of the movable rod 503 near the center of the placement table 202.

[0018] In this embodiment, the force balancing assembly includes two opposing racks 505. The racks 505 are bolted to opposite sides of the moving rod 503. The racks 505 are meshed with the same gear 506 on their inner sides. The gear 506 is rotatably connected to the top of the translation rod 403. Through the arrangement of the racks 505 and the gear 506, when the two clamping heads 504 of the same group approach the side of the mold, one of the clamping heads 504 contacts the mold surface first, while the other clamping head 504 can continue to approach the mold surface until the clamping heads 504 on both moving rods 503 are pressed against the side of the mold. This can adapt to molds with different shapes and uneven sides.

[0019] In this embodiment, the guide assembly includes a fixed rod 401, and several fixed rods 401 are arranged in a ring. The fixed rods 401 are bolted to the top of the worktable 101. A guide seat 402 is bolted to the fixed rod 401. A sliding groove is provided on the guide seat 402. A translation rod 403 is slidably connected in the sliding groove on the guide seat 402. With the setting of the screw 302, the translation rod 403 can move along the groove of the guide seat 402, making the clamping action more stable.

[0020] In this embodiment, the actuation assembly includes a rotating handle 204, which is bolted to the outside of the turntable 201. Several actuation pads 205 are attached to the rotating handle 204. The actuation pads 205 provide a force point for the operator to rotate the rotating handle 204, making it easier to use.

[0021] In this embodiment, the locking mechanism includes a fixing block 301, which is bolted to the top of the worktable 101. A screw 302 is threaded onto the fixing block 301, and a friction block 303 is bolted to one end of the screw 302. The friction block 303 is used to press against the actuating pad 205 to lock the movement of the rotating handle 204. The friction block 303 has a large coefficient of friction. When the screw 302 rotates, the screw 302 can push the friction block 303 to press against the actuating pad 205, thereby locking the rotation of the rotating handle 204, and further locking the rotation of the placement table 202, so that the clamping head 504 maintains stable clamping of the mold.

[0022] Working Principle: When using this device, first place the mold to be ground at the center of the top of the placement table 202, with the side of the mold to be ground facing upwards and adjust the mold's orientation to a suitable clamping angle. Then, the operator rotates the screw 302, which moves the friction block 303 away from the actuating pad 205. One hand holds the mold, while the other hand rotates the actuating pad 205. The actuating pad 205, through the rotating handle 204, drives the turntable 201 to rotate. The turntable 201 then drives the placement table 202 to rotate. As the placement table 202 rotates, under the pressure of the spiral groove 203, several moving seats 404 move synchronously. The moving seats 404 drive the translation rod 403 to move along the sliding groove direction of the guide seat 402. The translation rod 403, through the fixed seat 501, drives the guide rod 502 to move, and simultaneously, through the gear 506, drives the rack 505 to move, causing the two moving rods 503 to move synchronously. At this time, all moving rods 503 are facing the mold side. The mold moves along a surface. When one of the clamping heads 504 on the moving rod 503 contacts the side of the mold, while the other clamping heads 504 do not, the mold will be pushed by the first moving rod 503 to contact it. The moving rods 503 in the same group will drive the gear 506 to rotate through the rack 505 until both clamping heads 504 in the same group are in contact with the mold. This process continues until all the clamping heads 504 are in contact with the side of the mold and apply sufficient clamping force, thus completing the stable clamping of the mold. Then, the screw 302 is rotated, which drives the friction block 303 to approach the actuating pad 205. The screw 302 presses the friction block 303 against the side of the actuating pad 205, locking the turntable 201 and its rotation. Then, the hydraulic cylinder 601 and the motor are activated. The hydraulic cylinder 601 pushes the power assembly 602 downward to the surface to be ground at the top of the mold, and the motor drives the grinding disc 603 to rotate and grind the mold.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
