Description

Technical Field

[0001] This utility model belongs to the technical field of insert production equipment, specifically an insert processing device for die casting molds. Background Technology

[0002] Die casting molds are tools used to cast metal parts. They are tools used to complete the die casting process on a dedicated die casting and forging machine. Controlling the surface temperature of the die casting mold is very important for producing high-quality die castings. Uneven or inappropriate die casting mold temperatures can also lead to unstable casting dimensions, deformation of the casting during the production process, and defects such as thermal stress, sticking, surface depressions, internal shrinkage cavities, and hot bubbles.

[0003] Currently, when operators produce inserts in die-casting molds, they often need to use processing equipment. However, although the existing processing equipment has basic grinding functions, the clamping blocks in the equipment cannot rotate. This means that after grinding the top of the insert, the operator needs to release the clamping effect and manually rotate it before fixing it again. This process increases the operator's working time and causes inconvenience. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems. This invention provides an insert processing device for die-casting molds, which has the advantage of automatic rotation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a block processing device for die casting molds, comprising a table, a support plate and a connecting plate fixedly connected to the two sides of the top of the table, a movable shaft rotatably mounted on the support plate, and a first pneumatic cylinder rotatably mounted on the connecting plate, the movable shaft and the first pneumatic cylinder being arranged facing each other and both being fixedly connected to clamping blocks;

[0006] The first pneumatic cylinder is fixedly fitted with a gear on the other side of the connecting plate. A first motor is fixedly installed on the tabletop. A rotating shaft is fixedly fitted onto the output shaft of the first motor. One end of a long rod is fixedly fitted onto the outer surface of the rotating shaft. One end of a moving rod is hinged to the other end of the long rod. A connecting block is hinged to the other end of the moving rod. The connecting block is movably set on the tabletop. A toothed plate is fixedly connected to the connecting block. The toothed plate meshes with the gear.

[0007] As a preferred embodiment of this utility model, a T-shaped block is slidably connected inside the connecting block, the T-shaped block is fixedly set on the table, and a ring located inside the connecting plate is fixedly sleeved on the outer surface of the first pneumatic cylinder, the ring being rotatably set inside the connecting plate.

[0008] As a preferred embodiment of this utility model, table legs are fixedly connected to the four corners of the bottom of the tabletop, a long plate is fixedly connected to the top of the support plate, and the other end of the long plate is fixedly connected to the top of the connecting plate.

[0009] As a preferred embodiment of this utility model, a second pneumatic cylinder is fixedly installed at the top of the long plate, a second motor is fixedly connected to the bottom of the second pneumatic cylinder, a rotating shaft is fixedly sleeved on the output shaft of the second motor, and a grinding disc is fixedly connected to the bottom of the rotating shaft.

[0010] As a preferred embodiment of this utility model, a third motor is fixedly installed at the top of the support plate, a round shaft is fixedly sleeved on the output shaft of the third motor, a hollow block is fixedly sleeved on the round shaft, the hollow block has a strip groove, and a movable and sliding round rod is provided in the strip groove. A strip through hole is opened vertically on the support plate, and the other end of the round rod passes through the strip through hole and is fixedly connected to a protective cover.

[0011] As a preferred embodiment of this utility model, a moving block located inside the connecting plate is fixedly connected to the other side of the protective cover, and the outer surface of the moving block is slidably connected to the inside of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up gears, a first motor, a connecting block, and a toothed plate, allows the operator to start the first motor, which will cause the rotating shaft and the long rod to rotate. This causes the moving rod to pull the connecting block and the toothed plate forward. At this time, the outer surface of the toothed plate will mesh with the outer surface of the gear, which will then drive the first pneumatic cylinder, the two clamping blocks, and the movable shaft to rotate, thereby achieving automatic flipping. This avoids the need for the operator to first release the fixing effect and then manually flip it, bringing convenience to the operator.

[0014] 2. This utility model incorporates a third motor, a round shaft, a hollow block, a round rod, and a protective cover. When the operator starts the third motor, the round shaft and the hollow block rotate. This causes the inner surface of the hollow block to press and push the outer surface of the round rod, which in turn causes the round rod to move the protective cover and the moving block downwards. The bottom of the protective cover then contacts the top of the tabletop, thus shielding the sparks and debris generated during subsequent grinding operations and preventing them from splashing onto the operator's body.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides an insert processing device for die casting molds, including a tabletop 1. A support plate 2 and a connecting plate 3 are fixedly connected to the left and right sides of the top of the tabletop 1, respectively. A movable shaft 4 is rotatably mounted on the support plate 2. The right end of the movable shaft 4 passes through the support plate 2 and extends to the outside of the right side of the support plate 2. A first pneumatic cylinder 5 is rotatably mounted on the connecting plate 3. The left end of the first pneumatic cylinder 5 passes through the connecting plate 3 and extends to the outside of the left side of the connecting plate 3. Clamping blocks 6 are fixedly connected to the opposite sides of the movable shaft 4 and the first pneumatic cylinder 5.

[0023] The right end of the first pneumatic cylinder 5 passes through the connecting plate 3 and extends to the outside of the right side of the connecting plate 3, and a gear 7 is fixedly sleeved on its outer surface. The first motor 8 is fixedly installed in front of the right side of the desktop 1. The other end of the output shaft of the first motor 8 is fixedly sleeved with a rotating shaft 9. One end of a long rod 10 is fixedly sleeved on the outer surface of the rotating shaft 9. The other end of the long rod 10 is hinged to one end of a moving rod 11. The other end of the moving rod 11 is hinged to a connecting block 12. The connecting block 12 is movably set on the desktop 1. A toothed plate 13 is fixedly connected to the left side of the connecting block 12. The toothed plate 13 meshes with the gear 7.

[0024] When the operator starts the first motor 8, the rotating shaft 9 and the long rod 10 will rotate, which will cause the moving rod 11 to pull the connecting block 12 and the toothed plate 13 forward. This will cause the toothed plate 13 to drive the gear 7 to rotate, which will drive the first pneumatic cylinder 5, the two clamping blocks 6 and the movable shaft 4 to rotate (the first pneumatic cylinder 5 can rotate together on both sides when the insert is clamped by the clamping blocks 6), thus achieving automatic flipping, so that the operator does not need to release the fixing effect and then manually flip it.

[0025] The connecting block 12 is internally connected to a T-shaped block 14, the bottom end of which is fixedly connected to the top of the tabletop 1. A ring 27 located inside the connecting plate 3 is fixedly fitted onto the outer surface of the first pneumatic cylinder 5. The ring 27 is rotatably mounted inside the connecting plate 3. Due to the design of the T-shaped block 14 and the ring 27, the movement of the connecting block 12 and the first pneumatic cylinder 5 are effectively limited.

[0026] The tabletop 1 has four legs 15 fixedly connected to its bottom corners, and a long board 16 is fixedly connected to the top of the support plate 2. The right side of the bottom of the long board 16 is fixedly connected to the top of the connecting plate 3. Due to the design of the four legs 15, the tabletop 1 can be well supported.

[0027] A second pneumatic cylinder 17 is fixedly installed at the top of the long plate 16. The bottom end of the second pneumatic cylinder 17 passes through the long plate 16 and extends to the outside of the bottom end of the long plate 16, where a second motor 18 is fixedly connected. The other end of the output shaft of the second motor 18 is fixedly sleeved with a rotating shaft 19, and the bottom end of the rotating shaft 19 is fixedly connected to a grinding disc 20. When the operator operates the second pneumatic cylinder 17, the second motor 18 will move downwards as a whole.

[0028] A third motor 21 is fixedly installed at the top front of the support plate 2. A round shaft 22 is fixedly sleeved at the other end of the output shaft of the third motor 21, and a hollow block 23 is fixedly sleeved on the outer surface of the round shaft 22. When the operator starts the third motor 21, the round shaft 22 and the hollow block 23 will rotate.

[0029] The hollow block 23 has a slotted groove. One end of the round rod 24 is movably and slidably located within the slotted groove. A vertically oriented through-hole is formed on the support plate. The other end of the round rod 24 is slidably connected to the through-hole and is fixedly connected to a protective cover 25 through the through-hole. The protective cover 25 has openings on both sides larger than the movable shaft 4 and the first pneumatic cylinder 5, and an opening on the top larger than the second pneumatic cylinder to prevent interference during rotation. When the hollow block 23 rotates, it pushes the round rod 24, which in turn causes the protective cover 25 to move up and down. A moving block 26 is fixedly connected to the top right side of the protective cover 25, located inside the connecting plate 3. The outer surface of the moving block 26 is slidably inserted into the interior of the connecting plate 3. The design of the moving block 26 effectively guides the movement of the protective cover 25.

[0030] Working principle and usage process of this utility model:

[0031] First, the operator places the insert to be processed between two clamping blocks 6 and activates the first pneumatic cylinder 5. This causes the clamping block 6, fixed to the left side of the first pneumatic cylinder 5, to move to the left, thus clamping and fixing the insert between the two clamping blocks 6. Then, the operator operates the second pneumatic cylinder 17, the third motor 21, and the second motor 18. The operation of the second pneumatic cylinder 17 causes the second motor 18 to move downwards, thereby bringing the bottom of the grinding disc 20 into contact with the top of the insert. The operation of the three motors 21 causes the round shaft 22 and the hollow block 23 to rotate, which in turn causes the hollow block 23 to push the round rod 24, allowing the protective cover 25 and the moving block 26 to move downwards. This allows the bottom end of the protective cover 25 to contact the top end of the tabletop 1, preventing sparks and debris generated during subsequent grinding operations from flying onto the operator's body. Meanwhile, the operation of the second motor 18 causes the rotating shaft 19 and the grinding disc 20 to rotate, allowing the bottom end of the grinding disc 20 to grind the top end of the insert.

[0032] Finally, after the top of the insert is polished, the operator starts the first motor 8, causing the rotating shaft 9 and the long rod 10 to rotate. This causes the moving rod 11 to pull the connecting block 12 and the toothed plate 13 forward, so that the outer surface of the toothed plate 13 will mesh with the outer surface of the gear 7. This causes the gear 7 to drive the first pneumatic cylinder 5, the two clamping blocks 6 and the movable shaft 4 to rotate, so that the bottom of the insert can automatically flip up to face the polishing operation.
