Description

Technical Field

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

[0002] In industrial production, molds and tools used to obtain desired products through injection molding, die casting, or stamping are collectively referred to as molds. Molds typically consist of a fixed mold and a moving mold. Different cavities are used to produce products with different shapes and structures. Molds mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. Since the shape is changed by external force, molds have high requirements for structural strength, rigidity, and surface hardness.

[0003] When the products being manufactured require internal processing, inserts are often added to the mold. Different inserts can form different structures and shapes during the stamping process. Inserts are generally not finished products and can be customized according to the needs of the mold.

[0004] For example, application number CN201822002992.8 discloses a positioning mechanism for a mold insert, including a fixed mold. Both sides of the fixed mold have insertion grooves, and a positioning rod is located inside each groove. The positioning rod has a positioning screw hole on its surface, a locking seat at one end, a locking groove inside the locking seat, a locking block at the top of the locking groove, and a locking rod at the bottom of the locking block. An insert rod is located inside the fixed mold, with a positioning hole on one side of the insert rod and a fixing plate on one side of the locking block. The fixing plate has a first fixing screw hole on its surface. This invention, by providing a positioning rod, a positioning hole, and a clamping plate, facilitates positioning by inserting the positioning rod into the positioning hole and fixing by the clamping plate. Overall, this invention provides better fixing of the insert rod, increases stability, and thus improves product precision and quality.

[0005] Although the above comparative cases solved the corresponding technical problems, the above comparative cases still have the following defects: the above technical solutions use bolts to fix the inserts, and multiple bolts need to be turned frequently when replacing them. This is not only inconvenient to operate, but also inefficient, thus affecting practicality. Therefore, a mold insert processing device is proposed. Utility Model Content

[0006] Therefore, it is necessary to address the technical problem of using bolts to fix inserts, which requires frequent tightening of multiple bolts during replacement, resulting in inconvenience and low efficiency. To address this, a mold insert processing device is provided, comprising: a worktable, with fixed posts fixedly connected to the four corners of the worktable's upper surface; a top plate fixedly connected to the top of each fixed post; a hydraulic rod fixedly installed on the upper surface of the top plate; a lower mold fixedly connected to the upper surface of the worktable; a first slot formed on the inner bottom surface of the lower mold; a first groove formed on the inner bottom surface of the first slot; a second groove formed on one side of the inner wall of the first groove; an insert body installed in the first slot; and an insert block fixedly connected to the bottom surface of the insert body, with a through-hole... The system includes a limiting groove, an adjusting groove on one side of the inner wall of the second slot, an adjusting screw rotatably connected to the adjusting groove, a movable groove on the lower mold, a worm gear rotatably connected to the movable groove, the right end of the adjusting screw penetrating one side of the inner wall of the adjusting groove and extending into the movable groove; a worm wheel is fixedly connected to the right end of the adjusting screw, a slider is inserted around the periphery of the adjusting screw, a limiting block is fixedly connected to the upper surface of the slider, an upper mold is fixedly connected to the output end of the hydraulic rod, and straightening blocks are fixedly connected to the left, right, and rear sides of the upper mold, with pulleys rotatably connected to the bottom of the straightening blocks relative to their two surfaces; two sets of fixing blocks are fixedly connected to the left, right, and rear sides of the lower mold, with a guide groove on one side of each fixing block.

[0007] In one embodiment, the lower mold has symmetrically formed grooves, and a plurality of hollow tubes are fixedly connected to the inner surface of the grooves. A push rod is slidably connected inside the hollow tube, and a spring is fixedly connected to the bottom surface of the hollow tube. The bottom surface of the lower mold has symmetrically formed second slots, and a push block is provided in the second slot. A top rod is symmetrically fixedly connected to the bottom surface of the push block. The shape and size of the first slot are adapted to the insert body, the shape and size of the first slot are adapted to the insert block, the shape and size of the limiting groove are adapted to the second slot, and the shape and size of the limiting block are adapted to the limiting groove and the second slot. The first slot engages with the insert body, and the first slot engages with the insert block.

[0008] In one embodiment, the adjusting screw is threadedly engaged with the slider, the worm gear meshes with the worm wheel, a knob is fixedly connected to the free end of the worm gear, the limiting block is engaged with the limiting groove and the second slot, and the shape and size of the pulley are adapted to the guide groove.

[0009] In one embodiment, the top plate has symmetrically inserted sliding rods on its upper surface, the top plate and the sliding rods slide together, the bottom end of the sliding rod is fixedly connected to the upper surface of the upper mold, the shape and size of the second slot are adapted to the push block, the top end of the spring is fixedly connected to the bottom surface of the push rod, the top end of the push rod is fixedly connected to the bottom surface of the push block, and the shape and size of the push rod are adapted to the groove and cooperate with the groove.

[0010] In the operation of the aforementioned mold insert processing device, the insert body is inserted into the first slot, and then the insert block fixedly connected to the bottom surface of the insert body is inserted into the first slot. At this time, the limiting slot will be aligned with the second slot. Then, rotating the knob drives the worm gear to rotate. The worm gear meshes with the worm wheel, thereby driving the adjusting screw to rotate. The adjusting screw drives the slider with the threaded engagement on the circumferential side to move in the adjusting groove. This allows the limiting block fixedly connected to the upper surface of the slider to pass through the second slot and be inserted into the limiting groove for limiting and fixing. This achieves rapid installation of the insert body and improves the efficiency of insert body installation.

[0011] Simultaneously, the hydraulic rod is activated to push the upper mold downwards. During the downward movement, the straightening block is inserted between the two sets of fixed blocks. If the upper mold shifts, the pulleys on both sides of the bottom of the straightening block will move downwards from the guide groove to correct it. As the upper mold moves downwards, the ejector rod retracts into the groove. At the same time as the ejector rod retracts, it drives the push block to retract into the second slot. The push block squeezes the push rod, and the push rod squeezes the spring. After the processing is completed, the upper mold moves upwards and leaves. The spring resets and pushes the push rod, which pushes the push block upwards to disengage the processed mold. Attached Figure Description

During the downward movement, the straightening block 210 will be inserted between the two sets of fixed blocks 13. If the upper mold 21 is offset, the pulleys 211 on both sides of the bottom of the straightening block 210 will move downward from the guide groove 130 to perform correction. When the upper mold 21 moves downward, the ejector rod 18 retracts into the groove 17. At the same time as the ejector rod 18 retracts, it drives the push block 191 to retract into the second slot 19. The push block 191 squeezes the push rod 171, and the push rod 171 squeezes the spring 172. After the processing is completed, the upper mold 21 moves upward and away. The spring 172 resets and pushes the push rod 171. The push rod 171 pushes the push block 191 upward to disengage the processed mold.
