Description

Technical Field

[0001] This utility model relates to the field of injection molds, and more specifically, to a vertical injection molding anti-pressure mold insert hardware pin rotating drag thread. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] The push rods in some existing injection molds cannot meet the requirements of secondary linkage, which reduces the production efficiency of the mold. Therefore, we propose a vertical injection molding method to prevent the rotating drag thread of the mold insert hardware pin. Summary of the Invention

[0004] To solve the above problems, this utility model provides a vertical injection molding anti-compression molding insert hardware pin rotating drag thread, adopting the following technical solution:

[0005] A vertical injection molding anti-compression mold insert hardware pin rotating drag thread includes a machine base, a rotating shaft is fixedly installed at the top of the machine base, the bottom end of the rotating shaft passes through the machine base, a mold body is provided at the top of the machine base, a reduction motor is provided on one side of the mold body, a sliding platform is provided inside the mold body, and two symmetrically distributed thread bar bodies are slidably installed in the sliding platform, and a rotating pusher is slidably sleeved on the side wall of each of the two thread bar bodies.

[0006] By adopting the above technical solution, when the product is in use, the mold body releases high pressure, the geared motor sends a signal to drive the toothed rod body to rotate and pull the core. After pulling the core 31mm, a stop signal is given, and the toothed rod body remains stationary. Then, when processing the product, the slide pusher drives the toothed rod body to move and pull the core 44mm, achieving a secondary linkage effect. Then, the machine table rotates 180 degrees to facilitate subsequent passage through the existing robotic arm range. The geared motor sends a signal to reverse and drive the toothed rod body to rotate and reset. Then, the above operation can be repeated.

[0007] Furthermore, a groove is provided on one side of the row platform, and a row pusher is slidably installed in the groove.

[0008] By adopting the above technical solution, the action pusher slides within the groove, facilitating the re-drive of the tooth bar body.

[0009] Furthermore, two symmetrically distributed limiting blocks are fixedly installed on the inner wall of the groove, and the sliding push side wall is provided with a limiting groove that matches the limiting blocks.

[0010] By adopting the above technical solution, a limiting block is provided in the groove, and a limiting groove matching the limiting block is opened on the side wall of the sliding pusher. Through the cooperation of the limiting block and the limiting groove, the sliding pusher is restricted.

[0011] Furthermore, the tooth bar body has multiple grooves arranged in a ring array on its side wall, and the rotating pusher has sliders arranged in a ring array on its inner side.

[0012] By adopting the above technical solution, the rotary pusher and the tooth bar body are positioned by the engagement of the slider and the groove, which not only facilitates subsequent disassembly, but also restricts the rotation of the rotary pusher, which helps to maintain the stability of the tooth bar body and the rotary pusher transmission.

[0013] Furthermore, the inner wall of the chute is provided with rubber pads.

[0014] By adopting the above technical solution, the inner wall of the slide is provided with a rubber pad, which helps to increase the friction between the rotating pusher and the tooth bar body, thereby improving the stability of the assembly between the rotating pusher and the tooth bar body.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] (1) In this utility model, the geared motor and the toothed rod body are connected by the gear transmission of the prior art. The geared motor controls the rotation of the core pulling by 31mm. The toothed rod body and the rotating push core are slidably connected, which facilitates the subsequent secondary linkage of the equipment and facilitates subsequent disassembly, which is conducive to improving the use effect of the equipment.

[0017] (2) In this utility model, the tooth bar body and the rotating pusher are slidably assembled by a slider and a groove, which not only facilitates subsequent disassembly and assembly, but also restricts the rotation of the rotating pusher, which is beneficial to maintaining the stability of the tooth bar body and the rotating pusher transmission.

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0028] Please see Figure 1-4A vertical injection molding anti-compression molding insert hardware pin rotating drag thread includes a machine base 1. A rotating shaft 2 is fixedly installed at the top of the machine base 1, and the bottom end of the rotating shaft 2 passes through the machine base 1. A mold body 4 is provided at the top of the machine base 1. A reduction motor 3 is provided on one side of the mold body 4. A sliding platform 7 is provided inside the mold body 4. Two symmetrically distributed thread rod bodies 5 are slidably installed in the sliding platform 7. A rotating pusher 8 is slidably sleeved on the side wall of each of the two thread rod bodies 5. A groove 9 is opened on one side of the sliding platform 7, and a sliding pusher 6 is slidably installed in the groove 9. When the product is in use, the mold body 4 releases high pressure, and the reduction motor 3 sends a signal to drive the thread rod body 5 to rotate and pull the core. After pulling the core 31mm, a stop signal is given, and the thread rod body 5 remains stationary. Then, the product is processed. The sliding pusher 6 drives the thread rod body 5 to move and pull the core 44mm, achieving a secondary linkage effect. Then the machine base 1 rotates 180 degrees to facilitate subsequent passage through the existing robotic arm range. The reduction motor 3 sends a signal to drive the thread rod body 5 to rotate and reset in the opposite direction. Then the above operation can be repeated.

[0029] Two symmetrically distributed limiting blocks 10 are fixedly installed on the inner wall of the groove 9. The side wall of the sliding pusher 6 is provided with a limiting groove that matches the limiting blocks 10. The groove 9 is provided with limiting blocks 10, and the side wall of the sliding pusher 6 is provided with a limiting groove that matches the limiting blocks 10. Through the cooperation of the limiting blocks 10 and the limiting groove, the sliding pusher 6 is restricted.

[0030] The tooth rod body 5 has multiple grooves arranged in a ring array on its side wall, and the rotating pusher 8 has sliders arranged in a ring array on its inner side. The rotating pusher 8 and the tooth rod body 5 are positioned by the engagement of the sliders and grooves, which not only facilitates subsequent disassembly but also limits the rotation of the rotating pusher 8, thus helping to maintain the stability of the transmission between the tooth rod body 5 and the rotating pusher 8. The inner walls of the grooves are equipped with rubber pads, which helps to increase the friction between the rotating pusher 8 and the tooth rod body 5, thereby improving the stability of the assembly between the rotating pusher 8 and the tooth rod body 5.

[0031] The implementation principle of this utility model embodiment is as follows: When the product is in use, the mold body 4 releases high pressure, and the reduction motor 3 sends a signal to drive the tooth rod body 5 to rotate and pull the core. After pulling the core 31mm, a stop signal is given, and the tooth rod body 5 remains stationary. Then, the product is processed. The sliding pusher 6 drives the tooth rod body 5 to move and pull the core 44mm, achieving the effect of secondary linkage. Then, the machine table 1 rotates 180 degrees to facilitate subsequent passage through the existing robotic arm range. The reduction motor 3 sends a signal to drive the tooth rod body 5 to rotate and reset in the opposite direction. Then, the above operation can be repeated.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
