Description

Technical Field

[0001] This utility model relates to the field of mold assembly technology, specifically to a mold assembly for processing wire sheaths. Background Technology

[0002] The processing of cable sheaths is supported by the mold assembly. By putting elastic materials such as rubber and silicone into the customized mold cavity, the sheath is formed through processes such as injection molding, vulcanization or stamping. The mold assembly integrates the mold core, mold base, guide mechanism and feeding system, and precisely controls the key structures of the cable sheath such as hole diameter, length and anti-slip texture, to ensure that the product can tightly wrap the cable, isolate wear and provide protective insulation.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology: In general, after injection molding the cable sheath, the mold assembly will stick together, which will affect the subsequent unloading efficiency and thus affect the overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a mold assembly for processing wire sheaths, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold assembly for processing wire sheaths, including a base plate, guide posts fixedly connected to the top four sides of the base plate, a connecting plate bolted to the top of the base plate outside the guide posts, a lower mold assembly bolted to the top of the connecting plate, and an upper mold assembly slidably connected to the upper outer side of the guide posts.

[0006] The beneficial effects of this utility model are as follows: by setting the middle of one side of the top of the lower mold body to be inclined, the lower mold assembly will contact the extrusion block when it moves vertically upward. Then, the extrusion block will drive the lower mold bodies on both sides to move in opposite directions until the lower mold bodies on both sides can fit together, so that the subsequent injection molding process can be carried out. After the injection molding is completed, the lower mold assembly will lose contact with the extrusion block when it moves vertically downward. This allows the lower mold bodies on both sides to be reset by the elastic deformation of the spring, so that they can be separated from the outside of the material and avoid sticking to the material. This makes the subsequent unloading process more efficient, thereby improving production efficiency.

[0007] To enable the phantom to be reset: Further configured as follows: the lower mold assembly includes a lower mold base bolted to the top of the connecting plate, the top of the lower mold base having a sliding groove around its perimeter, a T-shaped block slidably connected to the inner side of the sliding groove, a spring installed on one side of the T-shaped block, one side of the spring being fixedly connected to the inner wall of the sliding groove, the inner dimension of the sliding groove being consistent with the outer dimension of the T-shaped block, and slots being formed in the middle of both sides of the top of the lower mold base.

[0008] By adopting the above technical solution, the lower mold bodies on both sides can be reset under the elastic deformation of the spring, thereby moving on the top of the lower mold base. During the movement, the stability of the movement is ensured by the limiting of the T-block and the sliding groove, avoiding the occurrence of positional deviation.

[0009] To enable the material to be cooled: Further configuration: a lower mold body is fixedly connected to the top of the T-shaped block, a positioning hole is opened at the top of the lower mold body, a water inlet pipe and a water outlet pipe are respectively installed at both ends of one side of the lower mold base, the middle part of one side of the top of the lower mold body is inclined, and the water inlet pipe and the water outlet pipe are connected through a pump body and a cooling mechanism.

[0010] By adopting the above technical solution, the inclined surface of the lower mold assembly will contact the extrusion block when it moves vertically upward, so that the lower mold body can move in opposite directions. The coolant in the cooling mechanism can enter through the water inlet pipe and then be discharged through the outlet pipe to cool the formed material.

[0011] To achieve more precise positioning during the injection molding process: Further configured as follows: the upper mold assembly includes an upper mold body slidably connected to the outside of the guide post, extrusion blocks are fixedly connected to both sides of the inner upper surface of the upper mold body, and positioning posts are fixedly connected to the four sides of the inner upper surface of the upper mold body.

[0012] By adopting the above technical solution, the inclined surface of the lower mold assembly will contact the extrusion block when it moves vertically upward, so that the lower mold body can move in opposite directions, thereby allowing the two lower mold bodies to fit together. After fitting together, the positioning pin enters the positioning hole, thus ensuring the accuracy of the position.

[0013] To achieve greater stability when the upper mold component moves: Further configuration: the top of the connecting plate is provided with a first guide hole around its perimeter that matches the external dimensions of the guide column, and the bottom of the base plate is connected to the lifting mechanism.

[0014] By adopting the above technical solution, the guide post can pass through the first guide hole, thereby ensuring the stability of the movement when the base plate drives the upper mold assembly to move through the connecting plate.

[0015] To achieve an efficient injection molding process: Further configuration: a second guide hole with the same external dimensions and structure as the guide post is provided around the top of the upper mold body, and an injection hole is provided in the middle of the top of the upper mold body, and the top of the upper mold body is connected to the injection molding mechanism.

[0016] By adopting the above technical solution, the guide post can move inside the second guide hole, thereby limiting its position. When the lower mold body and the upper mold body are in contact, the material can be injected through the injection hole by the injection molding mechanism.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0021] Please see Figures 1 to 3 The mold assembly for processing wire sheaths includes a base plate 1, guide posts 2 are fixedly connected to the top of the base plate 1 around its perimeter, a connecting plate 3 is bolted to the top of the base plate 1 outside the guide posts 2, a lower mold assembly 4 is bolted to the top of the connecting plate 3, and an upper mold assembly 5 is slidably connected to the upper outer part of the guide posts 2.

[0022] In this embodiment, as Figure 1 and Figure 2As shown, the lower mold assembly 4 includes a lower mold base 401 bolted to the top of the connecting plate 3. A sliding groove 402 is provided around the top of the lower mold base 401. A T-shaped block 403 is slidably connected to the inner side of the sliding groove 402. A spring 404 is installed on one side of the T-shaped block 403. One side of the spring 404 is fixedly connected to the inner wall of the sliding groove 402. The inner dimension of the sliding groove 402 is consistent with the outer dimension of the T-shaped block 403. A slot is provided in the middle of both sides of the top of the lower mold base 401.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, a lower mold body 405 is fixedly connected to the top of the T-shaped block 403. A positioning hole 406 is opened at the top of the lower mold body 405. A water inlet pipe 407 and a water outlet pipe 408 are respectively installed at both ends of one side of the lower mold base 401. The middle part of one side of the top of the lower mold body 405 is inclined. The water inlet pipe 407 and the water outlet pipe 408 are connected through a pump body and a cooling mechanism.

[0024] In this embodiment, as Figure 1 and Figure 3 As shown, the upper mold assembly 5 includes an upper mold body 501 that is slidably connected to the outside of the guide post 2. Extrusion blocks 502 are fixedly connected to both sides of the inner upper surface of the upper mold body 501, and positioning posts 503 are fixedly connected to the four sides of the inner upper surface of the upper mold body 501.

[0025] In this embodiment, as Figure 1 As shown, the top of the connecting plate 3 is provided with first guide holes around its perimeter that are consistent with the external dimensions of the guide column 2, and the bottom of the base plate 1 is connected to the lifting mechanism.

[0026] In this embodiment, as Figure 1 and Figure 3 As shown, the top of the upper mold body 501 has a second guide hole around its perimeter that matches the external dimensions of the guide post 2, and the top of the upper mold body 501 has an injection hole in the middle, and the top of the upper mold body 501 is connected to the injection molding mechanism.

[0027] The working process of the mold assembly used for processing the cable sleeve is as follows: First, connect the bottom of the base plate 1 to the lifting mechanism, and connect the top of the upper mold body 501 to the injection molding mechanism. Then, connect the water inlet pipe 407 and the water outlet pipe 408 through the pump body and the cooling mechanism. Next, start the lifting mechanism to make the base plate 1 drive the guide column 2, the connecting plate 3 and the lower mold assembly 4 to move vertically upward. At this time, the guide column 2 will slide in the second guide hole of the upper mold body 501. When the inclined surface of the lower mold body 405 contacts the extrusion block 502, the extrusion block 502 will squeeze the lower mold bodies 405 on both sides, causing the lower mold bodies 405 on both sides to move in opposite directions. At this time, the spring 404 will undergo elastic deformation, and the T-block 403 will slide inside the sliding groove 402. Then, the extrusion block 502 will enter the groove. The extrusion block 502 limits the lower mold body 405, causing the two sides of the lower mold body 405 to fit together. The movement continues until the positioning pin 503 enters the positioning hole 406, ensuring accurate positioning. Injection molding can then proceed. After injection molding, the material is cooled by the cooling mechanism. Once the material is formed, the lifting mechanism is activated, causing the base plate 1 to move vertically downwards. The positioning pin 503 disengages from the positioning hole 406, and the extrusion block 502 disengages from the slot, thus removing the limitation on the lower mold body 405. The lower mold body 405 then resets under the elastic deformation of the spring 404, detaching from the material and preventing adhesion. Unloading can then proceed.
