Technical Field

[0001] This utility model belongs to the field of machining technology, and in particular relates to a production mold for alloy caps. Background Technology

[0002] Alloy caps, such as aluminum alloy caps, are widely used in daily life due to their excellent characteristics such as lightweight, strong corrosion resistance, and strong sealing performance. They are commonly found in can lids, cosmetic lids, as well as in some industrial and electrical appliance fields. As the demand for alloy caps from downstream industries increases, the precision and functional design also increase. Now, production molds have become the core molding equipment.

[0003] However, existing production molds still have shortcomings that need improvement. When stamping iron plate blanks, deviations may occur, resulting in asymmetrical mold shapes and unreasonable structures. This will cause the shape and size to be inaccurate, and may cause the two straight edges of the mold to have different heights or angular deviations. Therefore, we provide a mold for alloy cap production based on common production molds to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a production mold for alloy caps to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a production mold for alloy caps, comprising: an upper mold base, a lower mold base, an upper mold, and a lower mold. The lower mold is fixedly installed above the upper mold base, and the upper mold is fixedly installed below the lower mold, with the upper mold located above the lower mold. A sliding groove is formed on the inner side of the lower mold base, and a ejector pin is slidably connected to the inner wall of the sliding groove. A push groove with an inclined angle is formed on the inner side of the ejector pin. A receiving groove is formed on the inner side of the lower mold base, and a top block is slidably connected to the inner wall of the receiving groove, with one end of the top block having an inclined angle. A spring is provided inside the receiving groove, and the end of the top block with the inclined angle is slidably connected to the inner wall of the push groove.

[0006] The lower mold base has a second sliding groove on its inner side. A push block is slidably connected to the inner wall of the second sliding groove, and the push block has an inclined angle. A guide rod is fixedly connected to one side of the push block, and a second spring is sleeved on the outside of the guide rod.

[0007] A push rod is fixedly connected to the lower part of the upper mold base, and a roller is provided at the lower end of the push rod, with the roller located above the push block.

[0008] In this technical solution, the push rod and the push block cooperate to fix the position of the billet.

[0009] In the above technical solution, one end of the spring is fixedly connected to one end of the top block located in the receiving groove, and the other end of the spring is fixedly connected to the inner wall of the receiving groove.

[0010] In this technical solution, a receiving groove provides a receiving space for the spring and the top block.

[0011] In the above technical solution, one end of the second spring is fixedly connected to one side of the push block, and the other end of the second spring is fixedly connected to the inner wall of the second slide groove.

[0012] In this technical solution, the second slide provides space for the pusher to move.

[0013] In the above technical solution, the number of ejector columns is two, and the two ejector columns are symmetrical.

[0014] In this technical solution, the material ejection column improves the ease of material ejection.

[0015] In the above technical solution, the number of push blocks is two sets, and the two sets of push blocks are symmetrical, with four push blocks in each set.

[0016] In this technical solution, multiple push blocks are used to make the billet more evenly stressed.

[0017] In the above technical solution, the inner side of the push rod is provided with a wheel groove, the inner wall of the wheel groove is fixedly connected to a rotating shaft, the inner wall of the roller is rotatably connected to the outer surface of the rotating shaft, and the roller is located inside the wheel groove.

[0018] In this technical solution, the roller is provided with a space by means of a groove.

[0019] In the above technical solution, further, a sliding sleeve is fixedly connected inside the upper mold base, and a guide post is fixedly connected above the lower mold base. There are four sliding sleeves and four guide posts, and the four sliding sleeves and four guide posts are located at the four corners of the upper mold base and the lower mold base.

[0020] This technical solution improves the stable operation of the upper and lower molds during opening and closing.

[0021] The beneficial effects of this utility model are:

[0022] 1. This is a production mold for alloy caps. Through the cooperation of a push rod, a push block, and a spring, the blank can be fixed and limited. When stamping begins, the push rod moves downward and contacts the inclined surface of the push block first. The roller on the push rod rolls downward on the inclined surface of the push block under pressure, causing the push block to move inward until the blank is fixed. This prevents misalignment, deviation, and asymmetrical mold shape or unreasonable structure during stamping, improving the stability and accuracy of the process. The blank will not move or deviate during stamping, but will be firmly fixed on the mold, making it more stable and accurate, and reducing the occurrence of defective workpieces.

[0023] 2. This is a production mold for alloy caps. Through the cooperation of a spring, a ejector pin, and an ejector block, the ejector pin moves up and down with the mold during stamping, while the ejector block moves left and right synchronously. After the mold is stamped, the ejector pin and the ejector block cooperate to separate the lower mold and the lower mold base, and push the mold out. Attached Figure Description

[0034] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0035] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0036] Example 1: This example provides a production mold for alloy caps, including: an upper mold base 15, a lower mold base 16, an upper mold 1, and a lower mold 2. The lower mold 2 is fixedly installed above the upper mold base 15, and the upper mold 1 is fixedly installed below the lower mold 2, with the upper mold 1 located above the lower mold 2. A sliding groove 6 is opened on the inner side of the lower mold base 16, and a ejector pin 20 is slidably connected to the inner wall of the sliding groove 6. A push groove 7 is opened on the inner side of the ejector pin 20, and the push groove 7 has an inclined angle. A receiving groove 18 is opened on the inner side of the lower mold base 16, and a top block 5 is slidably connected to the inner wall of the receiving groove 18, with one end of the top block 5 having an inclined angle. A spring 10 is provided inside the receiving groove 18, and the end of the top block 5 with the inclined angle is slidably connected to the inner wall of the push groove 7.

[0037] The inner side of the lower mold base 16 is provided with a slide groove 13. The inner wall of the slide groove 13 is slidably connected to a push block 14, and the push block 14 has an inclined angle. A guide rod 11 is fixedly connected to one side of the push block 14, and a spring 19 is sleeved on the outside of the guide rod 11.

[0038] A push rod 8 is fixedly connected to the lower part of the upper mold base 15. A roller 9 is provided at the lower end of the push rod 8, and the roller 9 is located above the push block 14.

[0039] In this process, during stamping, pressure is applied downwards by the push rod 8 of the upper die holder 15. The bottom end of the push rod 8 is equipped with a roller 9. The push block 14 has an inclined angle. When the push rod 8 moves downwards, the roller 9 and the inclined surface of the push block 14 first contact each other. As it continues to move downwards, pressure is continuously applied to the push block 14, causing it to contract inwards and thus position the blank at the center of the lower die 2, fixing the blank in place. Simultaneously, the push block 14 moves, compressing the second spring 19. The compressed spring 19 accumulates elastic potential energy, providing power for the push block 14 to reset. After stamping is completed, the upper die holder 15 moves upwards with the push rod 8, and the second spring 19 then pushes the push block 14 to reset. 4. As the spring 19 pushes back to its initial position, the ejector pin 20 can move up and down. When the upper mold 1 applies pressure to the blank, it pushes the ejector pin 20 down to the bottom of the slide groove 6. At the same time, as the ejector pin 20 moves downward, it pushes the top block 5 into the receiving groove 18 through the push groove 7. At the same time as the top block 5 moves, the spring 10 is compressed. After the upper mold 1 and the lower mold 2 have finished stamping the blank, the spring 10 pushes the top block 5 out of the receiving groove 18. The top block 5 pushes the ejector pin 20 upward through the push groove 7. At the same time as the ejector pin 20 moves upward, it pushes out the workpiece stamped inside the lower mold 2, thus completing the ejection operation.

[0040] Example 2: This example provides a production mold for alloy caps. In addition to the technical solutions of the above examples, it also has the following technical features: one end of spring 10 is fixedly connected to one end of top block 5 located in receiving groove 18, and the other end of spring 10 is fixedly connected to the bottom wall of receiving groove 18.

[0041] The spring-10 is used to transmit force through elastic deformation, providing reset power to the top block 5 and ensuring that the top block 5 returns to its initial position.

[0042] Example 3: This example provides a production mold for alloy caps. In addition to the technical solutions of the above examples, it also has the following technical features: one end of spring 19 is fixedly connected to one side of push block 14, and the other end of spring 19 is fixedly connected to the inner wall of slide groove 13.

[0043] Among them, the elastic deformation of spring 19 is used to transmit force and provide reset power for push block 14, ensuring that push block 14 returns to the initial position.

[0044] Example 4: This example provides a production mold for alloy caps. In addition to the technical solutions of the above examples, it also has the following technical features: the number of ejector pins 20 is two, and the two ejector pins 20 are symmetrical.

[0045] The core function of the ejector column 20 is to separate and eject the formed workpiece from the lower mold base 16 after the mold completes the material forming, ensuring that the workpiece can be smoothly removed.

[0046] Example 5: This example provides a production mold for alloy caps. In addition to the technical solutions of the above examples, it also has the following technical features: the number of push blocks 14 is two sets, and the two sets of push blocks 14 are symmetrical, with four push blocks 14 in each set.

[0047] Among them, the stroke control function has been added to the original push block 14 to achieve the purpose of limiting the billet. It has both the pushing function and the precise limiting function, strictly limiting the movement stroke of the billet, reducing the feeding deviation and improving the processing accuracy, ensuring the workpiece accuracy, reducing the feeding deviation, and can also perform positioning to reduce deviation and improve the forming accuracy.

[0048] Example 6: This example provides a production mold for alloy caps. In addition to the technical solutions of the above examples, it also has the following technical features: a wheel groove 12 is provided on the inner side of the push rod 8, a rotating shaft 17 is fixedly connected to the inner wall of the wheel groove 12, the inner wall of the roller 9 is rotatably connected to the outer surface of the rotating shaft 17, and the roller 9 is located inside the wheel groove 12.

[0049] Among them, four push rods 8 are fixedly connected to one side of the upper mold base 15, and there are a total of eight on both sides.

[0050] Example 7: This example provides a production mold for alloy caps. In addition to the technical solutions of the above examples, it also has the following technical features: a sliding sleeve 4 is fixedly connected inside the upper mold base 15, and a guide post 3 is fixedly connected above the lower mold base 16. There are four sliding sleeves 4 and four guide posts 3, and the four sliding sleeves 4 and four guide posts 3 are located at the four corners of the upper mold base 15 and the lower mold base 16.

[0051] Among them, the guide post 3 is a cylindrical precision part, which is fixedly connected to the four corners of the lower mold base 16. It serves as the reference axis of this mold to provide linear guidance and avoid mold misalignment. The sliding sleeve 4 is a cylindrical sleeve part that matches the guide post 3. It is fixedly connected to the four corners of the upper mold base 15 and has a high-precision inner hole inside. It provides a guiding channel for the guide post 3 and protects the guide post 3 and the mold body. The two are used together to solve the problem of accurate alignment and stable operation during the mold opening and closing process.

[0052] Working principle: When stamping begins using the die, the upper die holder 15 is perpendicular to the lower die holder 16, ensuring they are on the same horizontal line. As the upper die holder 15 moves towards the lower die holder 16, the sliding sleeve 4 and guide post 3 engage in guiding cooperation. This precise cooperation ensures the moving parts move smoothly in a fixed direction, preventing misalignment and guaranteeing equipment precision. The blank is placed between the upper die 1 and the lower die 2. Pressure drives the upper die 1 downward, precisely closing with the lower die 2 fixed to the lower die holder 16. Simultaneously, due to the upper die... The push rod 8 of the upper mold base 15 and the push block 14 of the lower mold base 16 are slightly higher than the upper mold 1 and the lower mold 2. Before precise closure, the roller 9 on the push rod 8 of the upper mold base 15 will contact the push block 14 of the lower mold base 16 first. Since the push block 14 and the guide rod 11 inside the slide groove 13 of the lower mold base 16 are slidably connected, while the push rod 8 of the upper mold base 15 continuously applies pressure to the inclined surface of the push block 14, the push groove 7 with an inclined angle inside the ejector post 20 in the slide groove 16 inside the lower mold base 16 will move synchronously with the lower mold 2. And the inner receiving groove 18 of the lower mold base 16... The top block 5 has an inclined angle at one end and is equipped with a spring 10. When the ejector pin 20 moves downward, it pushes the top block 5 through the push groove 7. The elastic deformation of the spring 10 causes the top block 5 to move inward. The roller 9 of the push rod 8 rolls from above to below the push block 14, causing the push block 14 to move inward through the guide rod 11 inside the slide groove 13 of the lower die base 16 until the blank is further fixed to prevent the blank from moving and misaligning during the stamping process. After stamping, the upper die base 15 drives the upper die 1 and the push rod 8 to move upward. When the push rod 8 rolls upward from the bottom of the push block 14... At the same time, the guide rod 11 inside the slide groove 13 is connected to the spring 19 outside. The elastic deformation of the spring 19 provides the force for the push block 14 to return to its initial position. When the upper mold base 15 and the push rod 8 return to their initial positions, the ejector column 20 begins to move upward. At the same time, due to the elastic deformation of the spring 10, the top block 5 moves outward along with the ejector column 20 until it returns to its initial position. Then, the ejector column 20 pushes upward until it separates the lower mold 2 and the lower mold base 16 and pushes out the finished workpiece.
