Description

Technical Field

[0001] The present invention relates to the technical field of molds, and particularly to a processing mold for a conversion head used for connecting cable protection sleeves. Background Art

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

[0003] With the continuous development of industrial production technology, conversion heads are usually manufactured by mold injection molding to meet the production requirements of large scale and high precision. However, there are some problems that need to be solved urgently in the existing processing molds for conversion heads used for connecting cable protection sleeves. In the mold injection molding process, generally, liquid material is injected into the mold cavity formed by the moving mold and the fixed mold from the top of the mold, and the material is cooled and shaped in the mold cavity to finally form the required conversion head product. But for the common molds of this type at present, the sealing effect at the mold clamping joint of the moving mold and the fixed mold is often poor. Due to the gaps at the joint seam when the molds are clamped, when injecting liquid material into the mold, the liquid material easily flows out along these gaps. This not only causes waste of materials, increases production costs, but also the material flows out of the gaps and solidifies around the mold, which is more troublesome to clean up later and affects production efficiency. In view of the problems of poor sealing effect and the resulting material waste and many product burrs existing in the existing conversion head processing molds, it is necessary to improve the mold structure to improve the sealing performance at the joint seam when the moving mold and the fixed mold are clamped, thereby improving production efficiency, reducing costs, and ensuring the quality of the conversion head product. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems mentioned in the above background art, and to provide a processing mold for a conversion head used for connecting cable protection sleeves.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: A processing mold for a conversion head used for connecting cable protection sleeves, including a fixed mold and a moving mold. The fixed mold and the moving mold are rotatably connected through a hinge. A convex mold is fixedly connected to the moving mold. A mold cavity is formed at a position corresponding to the convex mold on the fixed mold. Square grooves are symmetrically formed on the surfaces of the moving mold on both sides of the convex mold. Sealing strips are clamped inside the square grooves. The moving mold and the fixed mold are locked through buckles.

[0006] Preferably, the buckle includes a clamping seat, a fixing seat, a handle and a U-shaped fixing rod, one end of the handle is rotatably connected to the protrusion on the clamping 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, a clamping groove is provided on the clamping seat, and one end of the U-shaped fixing rod away from the connecting rod is clamped inside the clamping groove.

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

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

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

[0010] Preferably, a protrusion is fixedly connected to a surface of the movable mold facing the mold cavity, and a circular groove is provided on the surface at a position symmetrical to the protrusion.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are: 1. In the present invention, by providing square grooves on both sides of the upper convex mold of the movable mold and inserting sealing strips therein, the sealing effect of the joints between the movable mold and the fixed mold and between the molds when closing the molds is improved, and when the liquid material is injected from the top of the mold into the interior thereof, the material is prevented from flowing out along the gap between the movable mold and the fixed mold, causing material waste. At the same time, because the sealing is improved, it is also possible to avoid the generation of more burrs on the adapter after the shaping is completed, thereby reducing the workload of subsequent burr removal.

[0012] 2. In the present invention, by arranging protrusions and circular grooves on the surface of the movable mold facing the mold cavity, protrusions and grooves can be formed at corresponding positions on the adapter during the shaping process of the adapter, so that when one half of the adapter is docked with the other half of the adapter, the protrusion on one half of the adapter can be inserted into the corresponding limit groove on the other half of the adapter, avoiding misalignment of the two halves of the adapter combined together during use, so as not to affect the use effect.

[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0017] Embodiment 1: As Figure 1 - Figure 5 shown, the present invention provides a technical solution: a processing die for a conversion head used for connecting cable protection sleeves, including a fixed die 1 and a moving die 2. The fixed die 1 and the moving die 2 are rotationally connected through a hinge. A punch 7 is fixedly connected to the moving die 2. A mold cavity 6 is provided at a position corresponding to the punch 7 on the fixed die 1. Square grooves 8 are symmetrically provided on the surfaces of the moving die 2 on both sides of the punch 7. A sealing strip 9 is clamped inside the square grooves 8. The moving die 2 and the fixed die 1 are locked through a buckle 3. The buckle 3 includes a card seat 301, a fixed seat 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 card seat 301. A rotatable connecting rod 305 is arranged inside the handle 303 near the fixed seat 302. Both ends of the U-shaped fixing rod 306 penetrate through the connecting rod 305 and are fixedly connected to the connecting rod 305 through nuts. A card slot 304 is provided on the card seat 301. One end of the U-shaped fixing rod 306 away from the connecting rod 305 is clamped inside the card slot 304. The sealing strip 9 is made of natural elastic rubber material. The number of buckles 3 is two groups. The two groups of buckles 3 are symmetrically distributed on both sides of the middle of the surface of the fixed die 1. And the number of each group of buckles 3 is four. A first handle 4 is fixedly connected to the side of the fixed die 1. A second handle 5 is fixedly connected to the side of the moving die 2.

[0018] In this embodiment, by opening square grooves 8 on both sides of the punch 7 on the movable mold 2 and inserting sealing strips 9 therein, the sealing effect of the joints between the movable mold 2 and the fixed mold 1 when the molds are closed is improved, so as to avoid the material flowing out along the gap between the movable mold 2 and the fixed mold 1 when the liquid material is injected into the interior from the top of the mold, causing material waste. At the same time, because the sealing is improved, it is also possible to avoid the generation of more burrs on the adapter after the shaping is completed, thereby reducing the workload of subsequent burr removal. By setting the buckle 3, the staff can easily lock and unlock the mold, and two groups of buckles 3 with four buckles in each group are set, and the fixed mold The two sides of the middle part of the surface of the mold 1 are symmetrically distributed, so that the connection between the fixed mold 1 and the movable mold 2 is more uniform and stable, and the force is more balanced, avoiding gaps or looseness in the mold due to local uneven force during the injection molding process, ensuring the sealing of the entire mold closing state and the stability of the mold structure, which is helpful to improve the molding quality of the conversion head product and ensure the consistency of product dimensional accuracy and appearance; by fixing the first handle 4 on the side of the fixed mold 1 and the second handle 5 on the side of the movable mold 2, it is convenient for the operator to apply force when opening and closing the mold, so as to efficiently complete the opening and closing action of the mold, which is convenient for injection molding production and subsequent maintenance work.

[0019] Example 2: Figure 4 As shown, a protrusion 10 is fixedly connected to a surface of the movable mold 2 facing the mold cavity 6 , and a circular groove 11 is provided on the surface at a position symmetrical to the protrusion 10 .

[0020] In this embodiment, a protrusion 10 and a circular groove 11 are provided on the surface of the movable mold 2 facing the mold cavity 6, and bumps and grooves can be formed at corresponding positions on the adapter during the shaping process of the adapter, so that when one half of the adapter is docked with the other half of the adapter, the bump on one half of the adapter can be inserted into the corresponding limit groove on the other half of the adapter, thereby avoiding misalignment of the two halves of the adapter combined together during use, so as not to affect the use effect.

[0021] The working principle of this embodiment is as follows: when in use, first, before processing the conversion head for the cable adapter connection, the operator pulls the first handle 4 and the second handle 5, and utilizes the characteristics of the hinge rotation connection between the fixed mold 1 and the movable mold 2 to open the movable mold 2, so that the mold cavity 6 is in a completely exposed state, which is convenient for preliminary preparations such as cleaning and inspection of the mold cavity 6. After the preparations are completed, an appropriate amount of liquid material is prepared and placed in the corresponding feeding device, which is connected to the injection port at the top of the mold (the injection port is not reflected in the description, but the injection mold usually has this structure), and then the operator holds the first handle 4 and the second handle 5 again to make the movable mold The mold 2 rotates around the hinge and gradually approaches the fixed mold 1 to perform the mold closing operation. During the mold closing process, the sealing strips 9 in the square grooves 8 on both sides of the punch 7 on the movable mold 2 will be in close contact with the corresponding surface of the fixed mold 1, and use their good elasticity to fill the gap between the two to achieve a preliminary sealing effect. Then, the fixed mold 1 and the movable 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 clamped in the groove 304 on the clamping seat 301, and the handle 303 is held and pressed. One end of the handle 303 rotates on the fixed seat 302, and at the same time drives the connecting rod 305 and the U-shaped fixing rod fixedly connected thereto. The rod 306 moves, so that one end of the U-shaped fixed rod 306 is firmly inserted into the slot 304 of the holder 301, and then the remaining buckles 3 can be operated according to the above steps. After the mold is closed and locked, the liquid material is injected into the mold cavity 6 composed of the mold cavity 6 of the fixed mold 1 and the convex mold 7 of the movable mold 2 through the injection port at the top of the mold. After the material is injected, it is cooled and shaped in the mold cavity 6 to finally form a conversion head product for cable adapter connection. Due to the protrusion 10 and the circular groove 11 provided on the side of the movable mold 2 facing the mold cavity 6, during the shaping process of the adapter, the protrusion 10 and the circular groove 11 provided on the side of the movable mold 2 facing the mold cavity 6 can make the adapter in the shaping process. During the process, bumps and grooves are formed at corresponding positions, so that when one half of the adapter is docked with the other half of the adapter later, the bump on one half of the adapter can be inserted into the corresponding groove on the other half of the adapter, so as to avoid the misalignment of the two halves of the adapter combined during use, so as not to affect the use effect. After the product is cooled and formed, the operator reverses the buckle 3 to release the lock between the fixed mold 1 and the movable mold 2, and then holds the first handle 4 and the second handle 5 to open the movable mold 2, so that the molded conversion head product can be taken out of the mold cavity 6, completing a processing cycle, and then the above steps can be repeated to carry out the next round of conversion head processing and production operations.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
