Technical Field
[0001] This utility model belongs to the field of end cap injection molding technology, specifically an end cap mold. Background Technology
[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. An injection molding machine, also known as an injection machine or injection molding machine, is the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic plastics. Injection molding is achieved through an injection molding machine and a mold.
[0003] Existing end cap molds often have the capability to produce multiple end caps at once during the production process. However, when removing multiple end caps, workers often need to manually or with the help of tools to remove the end caps from the mold. In particular, because the mold and the finished product are closely fitted, the end caps are difficult to remove, which affects work efficiency.
[0004] Therefore, this utility model provides an end cap mold. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An end cap mold of this utility model includes a mold core, a mold cavity at the top of the mold core, and the mold cavity is sized to correspond to the mold core. A core block is provided at the bottom of the mold core, and multiple core blocks are correspondingly arranged. A cavity block is provided at the top of the mold cavity, and multiple cavity blocks are correspondingly arranged. A flow groove is opened at the top of the mold core, and a connecting block is provided inside the flow groove, with the connecting block sized to correspond to the flow groove. A flow notch is opened at the bottom of the mold cavity, and multiple flow notches are sized to correspond to the position of the connecting block. This step, by setting the flow groove and connecting block to connect adjacent product parts, provides convenience for workers to pick up materials, helps solve the problem of product parts being difficult to remove after injection molding, improves the flexibility and practicality of the end cap mold, and helps improve injection molding efficiency.
[0007] Preferably, a third limiting tube is fixedly connected to the bottom of the mold core, and multiple third limiting tubes are arranged correspondingly. A fourth limiting tube is fixedly connected to the bottom of the mold core, and multiple fourth limiting tubes are arranged correspondingly. A first limiting tube is fixedly connected to the top of the mold cavity, and multiple first limiting tubes are arranged correspondingly. A second limiting tube is fixedly connected to the top of the mold cavity, and multiple second limiting tubes are arranged correspondingly. This step assists the operator in positioning the mold core and mold cavity by setting the first, second, third, and fourth limiting tubes, thereby making the positioning of the mold core and mold cavity more accurate and faster, enhancing the practicality and applicability of the mold, helping to avoid misalignment of the mold core and mold cavity during injection molding, improving the yield rate of end cap production, and reducing waste.
[0008] Preferably, a second reinforcing rod is fixedly connected to the inner wall of the mold core, and multiple second reinforcing rods are arranged corresponding to the positions of the third and fourth limiting tubes. A second reinforcing rod is fixedly connected to the inner wall of the mold cavity, and multiple second reinforcing rods are arranged corresponding to the positions of the first and second limiting tubes. A first reinforcing rod is fixedly connected to the inner walls of the mold core and the mold cavity, and multiple first reinforcing rods are respectively arranged corresponding to the positions of the first and third limiting tubes. This step connects multiple limiting components by setting the first and second reinforcing rods, and increases the structural strength of the limiting components by increasing the fixed area. This helps to alleviate the deformation of the first, second, third, and fourth limiting tubes under stress, and extends the service life of the mold.
[0009] Preferably, the top of the mold core has a limiting groove, and multiple limiting grooves are arranged correspondingly. The bottom of the mold cavity has a limiting protrusion, and the multiple limiting protrusions are set to correspond to the size of the limiting groove.

[0010] Preferably, an exhaust pipe is fixedly connected to the bottom of the mold core, and multiple exhaust pipes are correspondingly arranged. This step discharges the air between the mold core and the mold cavity by setting the exhaust pipe, avoiding the residual air between the mold core and the mold cavity from affecting the closure of the mold core and the mold cavity, thereby making the closure of the mold core and the mold cavity more stable, improving the practicality of the end cap mold, and helping to improve the quality of the finished product.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Specific implementation examples are given below.
[0023] like Figures 1 to 5 As shown, an end cap mold according to an embodiment of the present invention includes a mold core 1, a mold cavity 2 at the top of the mold core 1, the mold cavity 2 being sized to correspond to the mold core 1, a core block 3 at the bottom of the mold core 1, and multiple core blocks 3 being arranged correspondingly, a cavity block 4 at the top of the mold cavity 2, and multiple cavity blocks 4 being arranged correspondingly, a flow groove 7 at the top of the mold core 1, a connecting block 8 inside the flow groove 7, the connecting block 8 being sized to correspond to the flow groove 7, and a flow notch 9 at the bottom of the mold cavity 2, the multiple flow notches 9 being positioned and sized to correspond to the connecting block 8. During operation, after each injection molding is completed, the operator can remove the product part using the connecting portion between adjacent product parts. During the injection molding process, the mold core 1 and the mold cavity 2 will align with each other and tighten. In close contact, the molten injection molding liquid will enter the mold core 1, mold cavity 2, core block 3, and cavity block 4 through cavity block 4. Since the top of the mold core 1 has a flow groove 7 and the bottom of the mold cavity 2 has a corresponding flow notch 9, part of the molten injection molding liquid will flow between the flow groove 7 and the connecting block 8, and eventually cool and solidify, forming a connecting part between multiple adjacent product parts. Since the bottom area of the flow groove 7 is larger than the bottom area of the connecting block 8, the operator can first remove the connecting block 8 after injection molding, and then remove the product part. This step, by setting the flow groove 7 and the connecting block 8 to connect adjacent product parts, provides convenience for the operator to remove materials, which helps to solve the problem that the product parts are not easy to remove after injection molding, improves the flexibility and practicality of the end cap mold, and helps to improve the injection molding efficiency.
[0024] like Figure 4 and Figure 5As shown, a third limiting tube 13 is fixedly connected to the bottom of the mold core 1, and multiple third limiting tubes 13 are arranged correspondingly. A fourth limiting tube 14 is fixedly connected to the bottom of the mold core 1, and multiple fourth limiting tubes 14 are arranged correspondingly. A first limiting tube 11 is fixedly connected to the top of the mold cavity 2, and multiple first limiting tubes 11 are arranged correspondingly. A second limiting tube 12 is fixedly connected to the top of the mold cavity 2, and multiple second limiting tubes 12 are arranged correspondingly. During operation, the operator can use the first limiting tube 11, second limiting tube 12, third limiting tube 13, and fourth limiting tube 14 to position the mold core 1 and the mold cavity 2 during injection molding, thereby aligning multiple core blocks 3 with the corresponding cavity blocks 4. During the process, since multiple first limiting tubes 11 correspond one-to-one with multiple third limiting tubes 13, and multiple second limiting tubes 12 correspond one-to-one with multiple fourth limiting tubes 14... With a one-to-one correspondence, the operator can simultaneously pass the rods on the equipment through the corresponding first limiting tube 11 and third limiting tube 13, and the corresponding second limiting tube 12 and fourth limiting tube 14, thereby ultimately achieving the limiting of mold core 1 and mold cavity 2. After the mold core 1 and mold cavity 2 are limited, they will be supported and move in the vertical direction. This step, by setting the first limiting tube 11, second limiting tube 12, third limiting tube 13, and fourth limiting tube 14, assists the operator in positioning the mold core 1 and mold cavity 2, making the positioning of mold core 1 and mold cavity 2 more accurate and faster, enhancing the practicality and applicability of the mold, helping to avoid misalignment of mold core 1 and mold cavity 2 during injection molding, improving the yield rate of end cap production, and reducing waste.
[0025] like Figure 4 and Figure 5As shown, a second reinforcing rod 17 is fixedly connected to the inner wall of the mold core 1, and multiple second reinforcing rods 17 are arranged corresponding to the positions of the third limiting tube 13 and the fourth limiting tube 14. A second reinforcing rod 17 is fixedly connected to the inner wall of the mold cavity 2, and multiple second reinforcing rods 17 are arranged corresponding to the positions of the first limiting tube 11 and the second limiting tube 12. A first reinforcing rod 16 is fixedly connected to the inner walls of the mold core 1 and the mold cavity 2, and multiple first reinforcing rods 16 are respectively arranged corresponding to the positions of the first limiting tube 11 and the third limiting tube 13. During operation, the sidewalls of the multiple second reinforcing rods 17 fixed to the inner wall of the mold core 1 are simultaneously perpendicular to the sidewalls of the third limiting tube 13 and the fourth limiting tube 14. The multiple second reinforcing rods 17 are fixedly connected to the inner sidewall of the mold cavity 2. Their sidewalls are also fixedly connected to the first limiting tube 11 and the second limiting tube 12. The first reinforcing rod 16 is fixedly connected to the inner sidewall of the mold core 1 and the mold cavity 2. Its sidewall is fixedly connected to the sidewall of the first limiting tube 11 and the third limiting tube 13 that it contacts. This step connects multiple limiting components by setting the first reinforcing rod 16 and the second reinforcing rod 17. By increasing the fixed area, the structural strength of the limiting components is increased. This helps to alleviate the deformation of the first limiting tube 11, the second limiting tube 12, the third limiting tube 13 and the fourth limiting tube 14 under stress, and extends the service life of the mold.
[0026] like Figure 2 and Figure 3 As shown, a limiting groove 5 is formed on the top of the mold core 1, and multiple limiting grooves 5 are correspondingly arranged. A limiting protrusion 6 is formed on the bottom of the mold cavity 2, and the multiple limiting protrusions 6 are sized to correspond to the limiting grooves 5. During operation, because the limiting grooves 5 on the top of the mold core 1 and the limiting protrusions 6 on the bottom of the mold cavity 2 correspond to each other, whenever misalignment occurs between the mold core 1 and the mold cavity 2, the mold core 1 and the mold cavity 2 will not be able to close due to the presence of the limiting grooves 5 and the limiting protrusions 6. Furthermore, because the limiting grooves 5 and the limiting protrusions 6 correspond one-to-one, if the mold... There is a slight misalignment between the mold core 1 and the mold cavity 2. With the help of the limiting groove 5 and the limiting protrusion 6, the operator can manually adjust the mold core 1 and the mold cavity 2 until all the limiting protrusions 6 fall into the limiting groove 5, thus completing the positioning of the mold core 1 and the mold cavity 2. This step, by setting the limiting groove 5 and the limiting protrusion 6 to position the mold core 1 and the mold cavity 2, assists the operator in adjusting the misalignment of the mold core 1 and the mold cavity 2, improves the fault tolerance and practicality of the end cap mold, helps to reduce the mold maintenance requirements, and extends the service life.
[0027] like Figure 2 and Figure 4As shown, an exhaust pipe 15 is fixedly connected to the bottom of the mold core 1, and multiple exhaust pipes 15 are arranged in a corresponding manner. During operation, whenever the mold core 1 and the mold cavity 2 close, the air between the mold core 1 and the mold cavity 2 can be discharged through the multiple exhaust pipes 15 fixed to the bottom of the mold core 1. This step, by setting the exhaust pipes 15 to discharge the air between the mold core 1 and the mold cavity 2, avoids the residual air between the mold core 1 and the mold cavity 2 from affecting the closure of the mold core 1 and the mold cavity 2, thereby making the closure of the mold core 1 and the mold cavity 2 more stable, improving the practicality of the end cap mold, and helping to improve the quality of the finished product.
[0028] like Figure 1 and Figure 3 As shown, the top of the core block 3 is provided with a plastic concave block 18, and multiple plastic concave blocks 18 are arranged in a circumferential array. The bottom of the cavity block 4 is fixed with a plastic protrusion 10, and multiple plastic protrusions 10 are arranged in a circumferential array. During operation, during the injection molding of the end cap, because the top of the core block 3 is provided with multiple plastic concave blocks 18 arranged in a circumferential array, and the bottom of the cavity block 4 is fixed with plastic protrusions 10 arranged in a circumferential array, the surface of the injection-molded product will be affected by the plastic concave blocks 18 and the plastic protrusions 10 to form a predetermined depression and protrusion. This step, by setting the plastic protrusions 10 and the plastic concave blocks 18, makes the end cap present a predetermined shape, making the end cap more convenient for users to grip and reducing slippage.
[0029] During operation, after each injection molding cycle, workers can remove the product parts using the connecting parts between adjacent parts. During injection molding, the mold core 1 and mold cavity 2 align and make close contact. Molten plastic flows from cavity block 4 into the space between mold core 1, mold cavity 2, core block 3, and cavity block 4. Because the top of mold core 1 has a flow groove 7, and the bottom of mold cavity 2 has a corresponding flow notch 9, some molten plastic flows between the flow groove 7 and connecting block 8, eventually cooling and solidifying, forming connecting parts between multiple adjacent product parts. Since the bottom area of the flow groove 7 is larger than the bottom area of the connecting block 8, workers can remove the connecting block 8 first after injection molding, and then remove the product parts. During injection molding, workers can use the first limiting tube 11, the second limiting tube 12, the third limiting tube 13, and the fourth limiting tube 14 to position the mold core 1 and the mold cavity 2, thereby aligning multiple core blocks 3 with the corresponding cavity blocks 4. Since the multiple first limiting tubes 11 correspond one-to-one with the multiple third limiting tubes 13, and the multiple second limiting tubes 12 correspond one-to-one with the multiple fourth limiting tubes 14, workers can simultaneously pass rods from the equipment through the corresponding first limiting tubes 11 and third limiting tubes 13, and the corresponding second limiting tubes 12 and fourth limiting tubes 14, thus ultimately achieving the positioning of the mold core 1 and the mold cavity 2. After the mold core 1 and the mold cavity 2 are positioned, they will be supported vertically. The movement involves multiple second reinforcing rods 17 fixed to the inner wall of the mold core 1, whose sidewalls are simultaneously fixed to the sidewalls of the third limiting tube 13 and the fourth limiting tube 14. Similarly, multiple second reinforcing rods 17 fixed to the inner wall of the mold cavity 2 have sidewalls simultaneously fixed to the first limiting tube 11 and the second limiting tube 12. The first reinforcing rods 16 fixed to the inner walls of the mold core 1 and the mold cavity 2 have sidewalls that are respectively fixed to the sidewalls of the first limiting tube 11 and the third limiting tube 13 they contact. Because the limiting groove 5 on the top of the mold core 1 corresponds to the limiting protrusion 6 at the bottom of the mold cavity 2, whenever misalignment occurs between the mold core 1 and the mold cavity 2, the presence of the limiting groove 5 and the limiting protrusion 6 ensures that the mold core 1... The mold cavity 2 will not be able to close. Since the limiting groove 5 and the limiting protrusion 6 correspond one-to-one, if there is a slight misalignment between the mold core 1 and the mold cavity 2, the operator can manually adjust the mold core 1 and mold cavity 2 using the limiting groove 5 and the limiting protrusion 6 until all the limiting protrusions 6 fall into the limiting groove 5, thus completing the positioning of the mold core 1 and mold cavity 2. Whenever the mold core 1 and mold cavity 2 close, the air between the mold core 1 and mold cavity 2 can be discharged through multiple vent pipes 15 fixed to the bottom of the mold core 1. During the end cap injection molding process, multiple plastic recesses 18 arranged in a circular array are opened on the top of the core block 3, and plastic protrusions 10 arranged in a circular array are fixed to the bottom of the cavity block 4.The surface of the injection-molded product will be affected by the plastic recesses 18 and the plastic protrusions 10, forming predetermined depressions and protrusions.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
