Description

Technical Field

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

[0002] In today's cable laying and application fields, cable protection sleeves play a crucial role. They can effectively protect cables, extend their service life, and ensure their safe and stable operation. In the connection of cable protection sleeves, adapters are often needed to achieve reliable connections between sleeves of different specifications or between sleeves and other components. Therefore, the quality of the adapters has a direct impact on the performance of the entire cable protection system.

[0003] With the continuous development of industrial production technology, adapters are typically manufactured using injection molding to meet the demands of large-scale, high-precision production. However, existing processing molds for adapters used in cable protection conduit connections present some problems that urgently need to be addressed in practical applications. In injection molding, liquid material is generally injected from the top of the mold into the cavity formed by the moving and fixed molds, allowing the material to cool and shape within the cavity to ultimately form the desired adapter product. However, commonly used molds often have poor sealing at the joint between the moving and fixed molds. Due to gaps at the mold joint, liquid material easily flows out through these gaps when injected into the mold. This not only leads to material waste and increased production costs, but also causes the material to solidify around the mold after flowing out, making subsequent cleaning difficult and affecting production efficiency. Given the poor sealing performance of the existing converter head processing molds and the resulting material waste and product burrs, it is necessary to improve the mold structure to enhance the sealing performance at the joint when the moving mold and the fixed mold are closed, thereby improving production efficiency, reducing costs, and ensuring the quality of converter head products. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a processing mold for a converter head for connecting cable protection sleeves.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a processing mold for a converter head for connecting cable protection sleeves, 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, square grooves are symmetrically provided on the surfaces of the movable mold on both sides of the punch, a sealing strip is inserted inside the square groove, and the movable mold and the fixed mold are locked together by a buckle.

[0006] Preferably, the buckle includes a buckle seat, a fixing seat, a handle, and a U-shaped fixing rod. One end of the handle is rotatably connected to a protrusion on the buckle seat. A rotatable connecting rod is provided inside the handle near the fixing seat. Both ends of the U-shaped fixing rod pass through the connecting rod and are fixedly connected to the connecting rod by nuts. The buckle seat is provided with a buckle groove, and the end of the U-shaped fixing rod away from the connecting rod is engaged inside the buckle groove.

[0007] Preferably, the sealing strip is made of natural elastic rubber.

[0008] Preferably, there are two sets of buckles, which are symmetrically distributed on both sides of the center of the surface of the fixed mold, and each set has four buckles.

[0009] Preferably, a first handle is fixedly connected to the side of the fixed mold, and a second handle is fixedly connected to the side of the moving mold.

[0010] 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.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by opening square grooves on both sides of the punch on the moving mold and inserting sealing strips into them, the sealing effect at the joint 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 adapter from having a lot of burrs after the molding is completed, reducing the amount of subsequent burr removal work.

[0013] 2. In this utility model, a protrusion and a groove are provided on the side of the moving mold facing the mold cavity. During the molding process of the adapter, a protrusion and a groove can be formed at the corresponding position on the adapter. This allows the protrusion on one half of the adapter to be inserted into the corresponding limiting groove on the other half of the adapter when the two halves of the adapter are joined together. This prevents the two halves of the adapter from misaligning during use, so as not to affect the performance. Attached Figure Description

[0021] 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.

[0022] 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.

[0023] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a technical solution: a processing mold for a converter head for connecting cable protection sleeves, including a fixed mold 1 and a movable mold 2. The fixed mold 1 and the movable mold 2 are rotatably connected by a hinge. A punch 7 is fixedly connected to the movable mold 2. A mold cavity 6 is opened on the fixed mold 1 at the position corresponding to the punch 7. Square grooves 8 are symmetrically opened on the surfaces of the movable mold 2 on both sides of the punch 7. A sealing strip 9 is inserted into the inside of the square grooves 8. The movable mold 2 and the fixed mold 1 are locked together by a buckle 3. The buckle 3 includes a buckle base 301, a fixing base 302, a handle 303 and a U-shaped fixing rod 306. One end of the handle 303 is rotatably connected to a protrusion 10 on the buckle base 301. Next, a rotatable connecting rod 305 is provided inside the handle 303 near the fixed base 302. The two ends of the U-shaped fixing rod 306 pass through the connecting rod 305 and are fixedly connected to the connecting rod 305 by nuts. The card seat 301 is provided with a card groove 304. The end of the U-shaped fixing rod 306 away from the connecting rod 305 is locked inside the card groove 304. The sealing strip 9 is made of natural elastic rubber. There are two sets of buckles 3. The two sets of buckles 3 are symmetrically distributed on both sides of the middle of the surface of the fixed mold 1, and there are four buckles 3 in each set. The side of the fixed mold 1 is fixedly connected to the first handle 4, and the side of the moving mold 2 is fixedly connected to the second handle 5.

[0024] In this embodiment, by opening square grooves 8 on both sides of the punch 7 on the moving mold 2 and inserting sealing strips 9 into them, the sealing effect at the joint between the moving mold 2 and the fixed mold 1 during mold closing is improved. This prevents material from flowing out along the gap between the moving mold 2 and the fixed mold 1 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 adapter after molding, reducing the workload of subsequent burr removal. By setting buckles 3, operators can easily lock and unlock the mold. Two sets of four buckles 3 are provided in each set on the fixed mold. The symmetrical distribution on both sides of the center of the surface of mold 1 makes the connection between the fixed mold 1 and the moving mold 2 more uniform and stable, and the force is more balanced. This avoids gaps or loosening of the mold due to uneven local force during injection molding, ensuring the sealing performance and stability of the mold structure in the entire mold-closed state. This helps to improve the molding quality of the conversion head product and ensure the consistency of product dimensional accuracy and appearance. The first handle 4 is fixed to the side of the fixed mold 1, and the second handle 5 is fixed to the side of the moving mold 2, which makes it convenient for operators to apply force when opening and closing the mold, so as to efficiently complete the mold opening and closing action, which facilitates injection molding production and subsequent maintenance.

[0025] Example 2: As Figure 4 As shown, a protrusion 10 is fixedly connected to one side of the moving mold 2 facing the mold cavity 6, and a circular groove 11 is provided on this side at a position symmetrical to the protrusion 10.

[0026] In this embodiment, a protrusion 10 and a circular groove 11 are provided on the side of the moving mold 2 facing the mold cavity 6. During the molding process of the adapter, protrusions and grooves can be formed at corresponding positions on the adapter. This allows the protrusion on one half of the adapter to be inserted into the corresponding limiting groove on the other half of the adapter when the two halves of the adapter are joined together. This prevents the two halves of the adapter from misaligning during use, thus avoiding affecting the performance.

[0027] The working principle of this embodiment is as follows: Before processing the adapter head for cable connectors, the operator pulls the first handle 4 and the second handle 5, utilizing the hinged connection between the fixed mold 1 and the moving mold 2 to open the moving mold 2, fully exposing the mold cavity 6. This facilitates cleaning, inspection, and other preparatory work. After preparation, a suitable amount of liquid material is placed in the corresponding feeding device, which is connected to the injection port at the top of the mold (the injection port is not shown in the description, but injection molds typically have this structure). Then, the operator again grasps the first handle 4 and the second handle 5, causing the moving mold... The moving mold 2 rotates around the hinge, gradually approaching the fixed mold 1 to perform a mold closing operation. During the mold closing process, the sealing strip 9 in the square groove 8 on both sides of the punch 7 on the moving mold 2 will make close contact with the corresponding surface of the fixed mold 1, using its good elasticity to fill the gap between the two and achieve a preliminary sealing effect. Then, the fixed mold 1 and the moving mold 2 are further locked by operating the buckle 3. When operating, first, the end of the U-shaped fixing rod 306 away from the handle 303 is initially locked in the slot 304 on the card seat 301. Hold the handle 303 and press it. One end of the handle 303 rotates on the fixed seat 302, which at the same time drives the connecting rod 305 and the U-shaped fixing rod fixedly connected to it. The movement of rod 306 causes one end of the U-shaped fixing rod 306 to be firmly engaged in the slot 304 of the card seat 301. Then, the remaining clips 3 are operated according to the above steps. After mold closing and locking are completed, liquid material is injected through the injection port at the top of the mold into the mold cavity 6 formed by the mold cavity 6 of the fixed mold 1 and the punch 7 of the moving mold 2. After the material is injected, it is cooled and shaped within the mold cavity 6, ultimately forming a cable adapter connector. Because of the protrusion 10 and circular groove 11 on the side of the moving mold 2 facing the mold cavity 6, during the adapter shaping process, the protrusion 10 and circular groove 11 on the side of the moving mold 2 facing the mold cavity 6 can ensure that the adapter is properly shaped. During the process, protrusions and grooves are formed at corresponding positions, so that when one half of the adapter is connected to the other half, the protrusion on one half of the adapter can be inserted into the corresponding groove on the other half of the adapter. This prevents misalignment of the two halves of the adapter during use, thus avoiding affecting the performance. After the product cools and solidifies, the operator reverses the operation of the buckle 3 to loosen the lock between the fixed mold 1 and the moving mold 2. Then, by holding the first handle 4 and the second handle 5, the moving mold 2 can be opened, and the formed adapter product can be taken out from the mold cavity 6, completing one processing cycle. The above steps can then be repeated for the next round of adapter processing and production.

[0028] 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.
