Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for processing cable protection sleeves. Background Technology

[0002] In the existing processing of cable protection sleeves, corresponding processing molds are often used to shape the sleeves. However, current conventional processing molds have some shortcomings that urgently need to be addressed. During the mold closing operation between the moving and fixed molds, the sealing effect at the joint is poor. For example, when liquid material needs to be injected into the mold from the top to form the cable protection sleeve, due to poor sealing, the liquid material easily flows out through the gap between the moving and fixed molds. This leads to material waste, increases production costs, and prevents the material from being fully utilized for sleeve forming. Furthermore, poor sealing also results in numerous burrs at the edges of the sleeve after shaping. To ensure sleeve quality, a significant amount of manpower, resources, and time are required for burr removal, reducing production efficiency and increasing the complexity of the production process. In view of the problems existing in the current technology, it is necessary to develop a new cable protection sleeve processing mold to overcome the sealing defects of existing molds, improve production efficiency, reduce production costs, and enhance the production quality of cable protection sleeves. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a cable protection sleeve processing mold.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cable protection sleeve processing mold, comprising a fixed mold and a movable mold, wherein the fixed mold and the movable mold are rotatably connected by a hinge, a punch is fixedly connected to the movable mold, a mold cavity is provided on the fixed mold corresponding to the position of the punch, and square grooves are symmetrically provided on the surfaces of the movable mold on both sides of the punch, and a sealing strip is fitted inside the square groove.

[0005] Preferably, the sealing strip is made of natural elastic rubber.

[0006] Preferably, a fixing block one is fixedly connected to the side of the moving mold, and a fixing block two is fixedly connected to the side of the fixed mold at the position corresponding to the fixing block one. The surfaces of the fixing block one and the fixing block two are respectively provided with slot one and slot two. The moving mold and the fixed mold are fixed together by a locking assembly. The locking assembly includes a one-way screw and nuts threaded to both ends of the one-way screw. The one-way screw is locked inside the slot one and slot two, and the two nuts abut against the fixing block one and the fixing block two.

[0007] Preferably, there are two sets of locking components, which are symmetrically distributed on both sides of the moving mold. Each set of locking components has six components, which are equidistantly distributed on one side of the moving mold.

[0008] Preferably, a second handle is fixedly connected to the side of the moving mold, and a first handle is fixedly connected to the side of the fixed mold.

[0009] Preferably, a protrusion is fixedly connected to one side of the moving mold facing the mold cavity, and a circular groove is formed on this surface at a position symmetrical to the protrusion.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by opening square grooves on both sides of the punch and inserting sealing strips into them, the sealing effect at the joints between the moving mold and the fixed mold and when the mold is closed is improved. This prevents the material from flowing out along the gap between the moving mold and the fixed mold when liquid material is injected into the mold from the top, thus avoiding material waste. At the same time, because the sealing performance is improved, it can also prevent the sleeve from having a lot of burrs after the molding is completed, reducing the amount of subsequent burr removal work.

[0012] 2. In this utility model, a protrusion and a circular groove are provided on the side of the moving mold facing the mold cavity. During the shaping process of the protective sleeve, a protrusion and a limiting groove can be formed at the corresponding position on the protective sleeve. This allows the protrusion on one half of the protective sleeve to be inserted into the corresponding limiting groove on the other half when the two halves of the protective sleeve are joined together. This prevents the two halves of the protective sleeve from misaligning during use, thus avoiding affecting the performance. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a cable protection sleeve processing mold, including a fixed mold 2 and a movable mold 1, which are rotatably connected by a hinge. A punch 3 is fixedly connected to the movable mold 1. A mold cavity 4 is opened on the fixed mold 2 at the position corresponding to the punch 3. Square grooves 14 are symmetrically opened on the surfaces of the movable mold 1 on both sides of the punch 3. A sealing strip 15 is fitted inside the square groove 14. The sealing strip 15 is made of natural elastic rubber. A fixing block 7 is fixedly connected to the side of the movable mold 1. A fixing block 8 is fixedly connected to the side of the fixed mold 2 at the position corresponding to the fixing block 7. A groove is opened on the surface of the fixing block 7 and the fixing block 8 respectively. 9 and slot 2 10, moving mold 1 and fixed mold 2 are fixed together by locking assembly 11. Locking assembly 11 includes one-way screw 111 and nuts 112 threaded to both ends of one-way screw 111. One-way screw 111 is locked inside slot 1 9 and slot 2 10. The two nuts 112 abut against fixing block 1 7 and fixing block 2 8. There are two sets of locking assemblies 11. The two sets of locking assemblies 11 are symmetrically distributed on both sides of moving mold 1. Each set of locking assemblies 11 has six locking assemblies 11. The six locking assemblies 11 are equidistantly distributed on one side of moving mold 1. Handle 2 6 is fixedly connected to the side of moving mold 1. Handle 1 5 is fixedly connected to the side of fixed mold 2.

[0022] In this embodiment, by opening square grooves 14 on both sides of the punch 3 and inserting sealing strips 15 therein, the sealing effect at the joints between the moving mold 1 and the fixed mold 2 during mold closing is improved. This prevents material from flowing out along the gap between the moving mold 1 and the fixed mold 2 when liquid material is injected into the mold from the top, thus avoiding material waste. Simultaneously, the improved sealing also prevents excessive burrs from forming on the sleeve after molding, reducing the workload of subsequent burr removal. The sealing strip 15 is made of high-temperature resistant natural elastic rubber, enabling it to adapt to the high-temperature environment of the mold when liquid material is injected, ensuring stable and reliable sealing performance. It is not easily damaged or deformed by high temperatures, thus maintaining a good sealing state for a long time, ensuring smooth production and stable product quality. By utilizing the fixing block 7... The fixing block 2 8 and its cooperating locking assembly 11, especially through the structure of the one-way screw 111 and nut 112, can conveniently and firmly fix the moving mold 1 and the fixed mold 2 together, ensuring that the mold will not loosen accidentally during the sleeve molding process, ensuring the tightness of the mold closing, and thus ensuring the accuracy and quality of product molding; through several locking assemblies 11, the moving mold 1 and the fixed mold 2 can be evenly and firmly fixed in various positions, the force is more balanced, and local loosening is avoided, further enhancing the tightness and stability of the mold closing, ensuring that the mold is in good condition during the sleeve molding process, and improving the consistency and quality stability of product molding; by fixing and connecting handle 2 6 and handle 1 5 to the sides of the moving mold 1 and the fixed mold 2 respectively, it is convenient for the operator to open and close the mold.

[0023] Example 2: Figure 4 As shown, a protrusion 12 is fixedly connected to the side of the moving mold 1 facing the mold cavity 4, and a circular groove 13 is provided on this side at a position symmetrical to the protrusion 12.

[0024] In this embodiment, a protrusion 12 and a circular groove 13 are provided on the side of the moving mold 1 facing the mold cavity 4. During the shaping process of the protective sleeve, protrusions and limiting grooves can be formed at corresponding positions on the protective sleeve. This allows the protrusion on one half of the protective sleeve to be inserted into the corresponding limiting groove on the other half when the two halves of the protective sleeve are joined together. This prevents the two halves of the protective sleeve from misaligning during use, thus avoiding affecting the performance.

[0025] The working principle of this embodiment is as follows: In use, the operator first opens the movable mold 1 and the fixed mold 2 by holding handle 6 on the movable mold 1 and handle 5 on the fixed mold 2, which are connected by hinges. At this time, necessary pre-treatment operations such as cleaning and inspection can be performed on the mold cavity 4 of the fixed mold 2. Next, the liquid material for molding the cable protection sleeve is prepared. Then, the movable mold 1 is closed, aligning the punch 3 on the movable mold 1 with the mold cavity 4 on the fixed mold 2. During the mold closing process, the sealing strips 15 in the square grooves 14 on both sides of the punch 3 of the movable mold 1 will tightly fit with the corresponding positions of the fixed mold 2, providing a sealing effect and preventing leakage during subsequent injection of liquid material. Leakage causes material waste, but improved sealing also prevents excessive burrs from forming the sleeve after molding, reducing subsequent deburring work. Meanwhile, the fixing block 7 on the side of the moving mold 1 corresponds to the fixing block 8 on the side of the fixed mold 2, locking the one-way screw 111 into the slots 9 and 10 respectively. Tightening the nuts 112 at both ends of the one-way screw 111 causes the nuts 112 to abut against the fixing blocks 7 and 8. Several locking components 11 securely fix the moving mold 1 and the fixed mold 2 together, ensuring tightness and stability of mold closing. Then, from the top of the mold towards the mold cavity 4... Liquid material is injected internally, and under the cooperation of the punch 3 and the mold cavity 4, the liquid material gradually forms a cable protection sleeve. Due to the protrusion 12 and the circular groove 13 on the side of the moving mold 1 facing the mold cavity 4, after the protective sleeve is formed, the protrusion 12 and the circular groove 13 on the side of the moving mold 1 facing the mold cavity 4 can form protrusions and limiting grooves at corresponding positions during the shaping process of the protective sleeve. This allows the protrusion on one half of the protective sleeve to be inserted into the corresponding limiting groove on the other half when the two halves of the protective sleeve are joined together later, so as to avoid misalignment of the two halves of the protective sleeve during use and thus avoid affecting the performance. After the material is fully shaped and cooled in the mold cavity 4, the operator loosens the nut 112 of the locking component 11 and opens the mold again by the handle, so that the formed cable protection sleeve can be taken out from the mold cavity 4, completing one processing cycle of the cable protection sleeve. The above operation can then be repeated for the next round of production.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
