Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a manual fine-tuning push-pull mechanism for molds. Background Art

[0002] In mold design, the size and position of the discharge port play a crucial role in the quality and production efficiency of products. Adjusting the size of the mold discharge port is to ensure the uniform flow of molten plastic in the cavity and avoid problems such as uneven filling and product deformation.

[0003] The adjustment of the size of the mold discharge port is closely related to the use of the adjustment block. By reasonably selecting and using the adjustment block, the size of the mold discharge port can be effectively adjusted. If the gap between the adjustment block and the mold hole is too large, the position of the adjustment block can be adjusted. Adjust the position of the adjustment block to the center position of the mold hole and adjust the distance between the adjustment block and the mold hole to change the size of the mold discharge port.

[0004] The fine-tuning push-pull mechanism of the related technology is as Figure 1 shown, including a fixed block 1 and a screw 2. The fixed block 1 is fixed on the module of the mold by bolts. The screw 2 is threadedly connected to the fixed block 1. One end of the screw 2 is connected to the adjustment block 3, and the other end of the screw 2 is for an operator to rotate and adjust.

[0005] The above-mentioned related technical solutions have the following defects: Considering the service life of the above fine-tuning push-pull mechanism, the fixed block needs to be made of a wear-resistant alloy material with a relatively high price, which results in a higher cost of the above fine-tuning push-pull mechanism. At the same time, if the fixed block is damaged, the entire fixed block needs to be replaced, and the cost of replacing parts is also relatively high. Summary of the Utility Model

[0006] In order to reduce the use cost of the fine-tuning push-pull mechanism, the present application provides a manual fine-tuning push-pull mechanism for molds.

[0007] The manual fine-tuning push-pull mechanism for molds provided by the present application adopts the following technical solutions:

[0008] A manual fine-tuning push-pull mechanism for molds includes a fixed block, a screw, and an adjustment block. The fixed block includes a wear-resistant block, a first block, and a second block. The first block is arranged in a C shape and forms an installation groove matching the wear-resistant block. The second block is detachably connected to the first block to block the opening of the installation groove. The first block and the second block are provided with through holes for the screw to pass through. The wear-resistant block is provided with a first threaded hole matching the screw. The first block is detachably connected to the module of the mold. The adjustment block is provided with a second threaded hole matching the screw. The adjustment block is slidably connected to the second block along the axial direction of the screw. The screw is sequentially connected to the first block, the wear-resistant block, the second block, and the adjustment block.

[0009] By adopting the above technical solution, the fixed block is split into several parts. The wear-resistant block is one of the parts of the fixed block. Due to the material requirements, the cost of the wear-resistant block is relatively higher than that of other parts. At the same time, after the wear-resistant block is damaged, only the wear-resistant block needs to be replaced separately. Therefore, the use cost of the entire fine-tuning push-pull mechanism can be reduced.

[0010] Preferably, the adjusting block includes an adjusting rod and a square limiting block. The limiting block is fixedly sleeved on the adjusting rod. The second threaded hole is opened on the adjusting rod. A chute matching the limiting block is opened on the second block along the axis of the screw rod. The chute communicates with the through hole, and the limiting block slides on the chute.

[0011] Preferably, the chute penetrates through the second block.

[0012] By adopting the above technical solution, the installation of the second block and the adjusting block can be facilitated, and at the same time, the moving stroke of the adjusting block can be increased.

[0013] Preferably, at least two positioning blocks are provided on one side surface of the second block facing the first block, and positioning grooves matching the positioning blocks are opened on the first block.

[0014] By adopting the above technical solution, the connection stability between the first block and the second block can be improved.

[0015] Preferably, two countersunk holes are penetrated through the first block, and the two countersunk holes are respectively located on both sides of the through hole. Two through holes corresponding to the two countersunk holes are opened on the second block. The first block and the second block are fixedly connected by two bolts. The bolts pass through the countersunk holes and the corresponding through holes and are then threadedly connected to the module.

[0016] By adopting the above technical solution, the bolts can fix the first block and the second block on the module at one time.

[0017] Preferably, the screw rod has a first threaded section and a second threaded section. The pitch of the first threaded section is greater than the pitch of the second threaded section. The first threaded hole cooperates with the first threaded section, and the second threaded hole cooperates with the second threaded section.

[0018] By adopting the above technical solution, the adjustment accuracy of the adjusting block can be improved.

[0019] Preferably, the wear-resistant block is made of copper alloy material.

[0020] By adopting the above technical solution, copper alloy has good corrosion resistance and can maintain stable performance in many environments. At the same time, it has good strength and hardness, can withstand greater pressure and wear, and is more suitable for use in the manual fine-tuning push-pull mechanism.

[0021] The technical effects of the present utility model are mainly reflected in the following aspects:

[0022] 1. The present utility model splits the fixed block into several parts. The wear-resistant block is one of the parts of the fixed block. Due to the material requirements, the cost of the wear-resistant block is relatively high compared to other parts. At the same time, after the wear-resistant block is damaged, only the wear-resistant block needs to be replaced separately, so the use cost of the entire fine-tuning push-pull mechanism can be reduced;

[0023] 2. The screw of the present utility model has a first thread section and a second thread section. The pitch of the first thread section is greater than that of the second thread section, which can improve the adjustment accuracy of the adjustment block. Description of the Drawings

The fixed block 1 includes a wear-resistant block 11, a first block 12, and a second block 13. The first block 12 is arranged in a C shape and forms an installation groove 121 that matches the wear-resistant block 11. The second block 13 is detachably connected to the first block 12 to block the opening of the installation groove 121. Through holes 14 for the screw 2 to pass through are provided on the first block 12 and the second block 13. A first threaded hole 111 that matches the screw 2 is provided on the wear-resistant block 11. The first block 12 is detachably connected to the module of the mold. A second threaded hole 321 that matches the screw 2 is provided on the adjusting block 3. The adjusting block 3 is slidably connected to the second block 13 along the axial direction of the screw 2. The screw 2 is sequentially connected to the first block 12, the wear-resistant block 11, the second block 13, and the adjusting block 3.

[0033] Referring to Figures 2-4 , the fixed block 1 is split into several parts. The wear-resistant block 11 is one of the parts of the fixed block 1. Due to material requirements, the cost of the wear-resistant block 11 is relatively high compared to other parts. At the same time, after the wear-resistant block 11 is damaged, only the wear-resistant block 11 needs to be replaced separately. Therefore, the use cost of the entire fine-tuning push-pull mechanism can be reduced.

[0034] Referring to Figures 2-4 , the adjusting block 3 includes an adjusting rod 32 and a square limiting block 31. The limiting block 31 is fixedly sleeved on the adjusting rod 32. The second threaded hole 321 is provided on the adjusting rod 32. A sliding groove 133 that matches the limiting block 31 is provided on the second block 13 along the axial direction of the screw 2. The sliding groove 133 communicates with the through hole 14. The limiting block 31 slides on the sliding groove 133.

[0035] Referring to Figure 3 , the sliding groove 133 penetrates through the second block 13. It can facilitate the installation of the second block 13 and the adjusting block 3, and at the same time increase the moving stroke of the adjusting block 3.

[0036] Referring to Figures 3-5 , at least two positioning blocks 131 are provided on the side surface of the second block 13 facing the first block 12. Positioning grooves 122 that match the positioning blocks 131 are provided on the first block 12. It can improve the connection stability between the first block 12 and the second block 13.

[0037] Referring to Figures 2-4 , two countersunk holes 123 are provided through the first block 12. The two countersunk holes 123 are respectively located on both sides of the through hole 14. Two through holes 132 corresponding to the two countersunk holes 123 are provided on the second block 13. The first block 12 and the second block 13 are fixedly connected by two bolts. The bolts pass through the countersunk holes 123 and the corresponding through holes 132 and are then threadedly connected to the module. The bolts can fix the first block 12 and the second block 13 on the module at one time. After the second block 13 is fixed, it abuts against the wear-resistant block 11.

[0038] Reference Figures 2-4 , the screw rod 2 has a first thread section 21 and a second thread section 22. The pitch of the first thread section 21 is greater than that of the second thread section 22. The first threaded hole 111 is engaged with the first thread section 21, and the second threaded hole 321 is engaged with the second thread section 22. The adjustment accuracy of the adjustment block 3 can be improved.

[0039] Reference Figures 2-4 , the wear-resistant block 11 is made of a copper alloy material. The copper alloy has good corrosion resistance and can maintain stable performance in many environments. At the same time, it has good strength and hardness, can withstand greater pressure and wear, and is more suitable for use in a manual fine-tuning push-pull mechanism.

[0040] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
