Description

Technical Field

[0001] This utility model relates to the field of plastic processing, and in particular to a top-type shaping device for plastic products. Background Technology

[0002] Plastic products are items with a certain shape and function made from synthetic or natural resins as the main raw materials, with the addition of various additives, and through specific molding processes. The top-type shaping device for plastic products refers to the top block moving towards the part of the plastic product that needs to be shaped under the drive of the power system, according to a preset path and force, and applying pressure, so that the plastic product undergoes plastic deformation under pressure, thereby achieving the purpose of changing its shape, correcting dimensional deviations, or eliminating local defects.

[0003] When plastic products need to be shaped, the staff will select abutment blocks with appropriate spacing according to the specifications of the plastic products. Then, the plastic products are placed on the abutment blocks and suction blocks. The suction blocks are used to position the device, and then the hydraulic device is used to apply downward pressure to the plastic products, causing them to plastically deform and change their shape.

[0004] The existing technology has the following drawbacks: In some existing equipment, the spacing of the abutment blocks is fixed. For plastic products of different specifications, abutment blocks with different spacing need to be replaced. The replacement process is cumbersome, time-consuming and labor-intensive. In addition, the abutment blocks are in frequent contact with the product and are prone to wear. The replacement of the abutment blocks requires multiple bolt tightening operations, which is also cumbersome. Therefore, an abutment-type shaping device for plastic products is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a top-mounted shaping device for plastic products, aiming to solve the problem that the existing technology cannot adapt to plastic products of different specifications.

[0011] The slider is slidably connected to the top of the base.

[0012] As a further description of the above technical solution:

[0013] The workbench is provided with a transverse through groove, and the outer wall of the abutment block is provided with a ring.

[0014] As a further description of the above technical solution:

[0015] The moving ring has a circular hole, the inner diameter of which is larger than the outer diameter of the abutment block.

[0016] As a further description of the above technical solution:

[0017] The base has multiple slots at its top, and the length of each slot is greater than the length of the rotating rod.

[0032] 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.

[0033] Reference Figures 1-3This utility model provides an embodiment of a plastic product shaping device with a top-mounting mechanism, comprising a base 1 that supports the entire device. A worktable 2 is fixedly connected to the top of the base 1, and a movable ring 3 is slidably connected to the top of the worktable 2. A fixed ring 5 is elastically connected to the top of the movable ring 3 via a movable spring 4. When the fixed ring 5 moves downward, the movable spring 4 is compressed. Upon resetting, the fixed ring 5 is reset by the elastic force of the movable spring 4. The top of the fixed ring 5 contacts a top-mounting block 6, and a connecting rod 7 is inserted into the outer wall of the top-mounting block 6. The connecting rod 7 has a slot corresponding to the top-mounting block 6. The top-mounting block 6 is initially inserted into the slot of the connecting rod 7. A slider 11 is hinged to the bottom of the connecting rod 7 via a hinge rod 10. With a fixed length, when the slider 11 moves backward with one end of the hinge rod 10, the other end of the hinge rod 10 will bring the two sets of connecting rods 7 closer together. When the slider 11 moves forward with one end of the hinge rod 10, the other end of the hinge rod 10 will separate the two sets of connecting rods 7. The inner wall of the slider 11 is provided with a limit mechanism, and the bottom end of the inner wall of the connecting rod 7 is provided with a disassembly component. The limit mechanism includes a rotating rod 12, which is rotatably connected to the inner wall of the slider 11. The slider 11 has a slot corresponding to the rotating rod 12 to facilitate the rotation of the rotating rod 12. The outer wall of the rotating rod 12 is elastically connected to the slider 11 through a torsion spring 13. When the rotating rod 12 rotates counterclockwise, the torsion spring 13 is compressed. When resetting, the elastic force of the torsion spring 13 is used to reset the rotating rod 12.

[0034] Reference Figure 3 and Figure 5 The disassembly assembly includes a plug 8. The outer wall of the plug 8 is elastically connected to the connecting rod 7 via a moving spring 9. When the plug 8 moves backward, the moving spring 9 is compressed. When resetting, the elastic force of the moving spring 9 is used to reset the plug 8. The plug 8 is slidably connected to the bottom end of the connecting rod 7. The connecting rod 7 has a slot corresponding to the plug 8, allowing the plug 8 to move back and forth. The plug 8 is engaged with the outer wall of the abutment block 6. The abutment block 6 has a vertical opening. When the abutment block 6 moves vertically, the plug 8 will not block the abutment block 6.

[0035] Reference Figures 2-4 The slider 11 is slidably connected to the top of the base 1. The base 1 has a slot corresponding to the slider 11, so that the slider 11 can move back and forth. The worktable 2 has a transverse through slot, so that the abutment block 6 can move left and right. The outer wall of the abutment block 6 is provided with a ring, so that the abutment block 6 can squeeze the fixed ring 5 to move downward. The moving ring 3 has a round hole, the inner diameter of which is larger than the outer diameter of the abutment block 6. The top of the base 1 has multiple sets of slots, the length of which is greater than the length of the rotating rod 12. The rotating rod 12 is engaged with the top of the worktable 2.

[0036] Working principle: When it is necessary to reduce the distance between the abutment blocks 6, rotate the lever 12 counterclockwise. The lever 12 will compress the torsion spring 13. When the lever 12 separates from the slot on the base 1, move the slider 11 backward. The slider 11 will move the hinge rod 10 backward. The other end of the hinge rod 10 will bring the two sets of connecting rods 7 closer together. The two sets of connecting rods 7 will bring the two sets of abutment blocks 6 closer together, reducing the distance between the abutment blocks 6. At this time, the lever 12 coincides with the slot on the base 1. Release the lever 12, and use the elasticity of the torsion spring 13 to move the lever 12... The lever 12 is inserted into the slot on the base 1 to limit the position of the abutment block 6. To increase the spacing between the abutment blocks 6, rotate the lever 12 counterclockwise. When the lever 12 separates from the slot on the base 1, move the slider 11 forward. The slider 11 will move the hinge rod 10 forward, causing the other end of the hinge rod 10 to separate the two sets of abutment blocks 6, increasing the spacing between them. Once the adjustment is complete, release the lever 12, allowing it to engage with the slot on the base 1 to limit the position of the abutment block 6. To readjust the spacing between the abutment blocks 6, simply repeat the above steps.

[0037] When the abutment block 6 needs to be removed, move the insert block 8 backward. The insert block 8 will compress the moving spring 9. When the insert block 8 separates from the slot on the abutment block 6, remove the abutment block 6 upward. Then, release the insert block 8 and use the elastic force of the moving spring 9 to move the insert block 8 back to the initial position. When the abutment block 6 needs to be installed, move the insert block 8 backward. When the insert block 8 no longer obstructs the abutment block 6, align the abutment block 6 and insert it into the slot of the fixing ring 5. When the ring on the abutment block 6 contacts the fixing ring 5, release the insert block 8 and let the insert block 8 engage with the slot of the abutment block 6, thus completing the limiting of the abutment block 6. If the abutment block 6 needs to be installed and removed again, simply repeat the above steps.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
