Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for an automotive water chamber. Background Technology

[0002] Automotive water chamber injection molds are high-precision steel tools specifically designed for producing plastic water chamber housings—key components in automotive engine cooling systems. They utilize high-temperature molten plastic injected into a mold cavity under high pressure, rapidly cooling and shaping the complex form required for the water chamber. This ensures uniform wall thickness, precise dimensions, and reliable sealing, enabling efficient mass production to meet the stringent requirements of automotive cooling systems.

[0003] Automotive water chamber injection molds may experience a decrease in precision after a specified number of uses, requiring maintenance. Some existing automotive water chamber injection molds do not have an automatic counting function, so users cannot keep track of the number of uses since the last maintenance, which can easily lead to untimely maintenance. In such cases, batches of automotive water chamber products may fail to meet standards, causing significant economic losses to users. Utility Model Content

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-5 As shown, this utility model provides a technical solution: an injection mold for automotive water chambers, comprising: The lower mold 1 has an upper mold 11 on its top, and an injection port 12 is fixedly connected to the top of the upper mold 11. Automatic counting mechanism 2 is installed on the lower mold 1 and the upper mold 11. Automatic counting mechanism 2 is used to count the number of times the lower mold 1 and the upper mold 11 are closed. The prompting mechanism 3 is installed on the automatic counting mechanism 2 and is used to provide light prompts to the user. The automatic counting mechanism 2 includes a connecting block 21, a support sleeve 22, and a mounting base 25. The connecting block 21 is fixedly installed on the outer wall of the upper mold 11, and the support sleeve 22 is fixedly installed on the outer wall of the lower mold 1. A cylinder 23 is fixedly installed on the inner wall of the support sleeve 22. An air pipe 24 is threadedly connected to the bottom of the cylinder 23, and a square tube 29 is threadedly connected to the end of the air pipe 24 away from the cylinder 23. A support frame 28 is fixedly installed on the top of the mounting base 25, and the square tube 29 is fixedly installed on the inner wall of the support frame 28. A controller 26 is fixedly installed on the top of the mounting base 25, and a press counter 27 is fixedly installed on the top of the mounting base 25. The press counter 27 is located below the square tube 29. The lower mold 1 and the upper mold 11 are closed. Then, injection molding is performed from injection port 12. After cooling, the mold is separated to obtain the automotive water chamber product. After the lower mold 1 and the upper mold 11 are closed, the connecting block 21 will squeeze the cylinder 23 as a whole, and the gas inside the cylinder 23 will be delivered to the inner cavity of the square cylinder 29 in a pulse manner through the air pipe 24. The gas will push the moving plate 293 downward. The counting rod 294 will trigger the press counter 27 to count once, thereby realizing the automatic counting function. The mounting base 25 can be installed in a position away from the lower mold 1 and the upper mold 11 to avoid the problem that the high temperature on the lower mold 1 and the upper mold 11 will easily affect the service life of components such as the press counter 27. The actual length of the air pipe 24 is designed according to the usage environment.

[0017] As one implementation method in this embodiment, such as Figure 3 As shown, a first elastic element 231 is fixedly installed at the bottom of the inner wall of the cylinder 23, and a slider 232 is fixedly installed at the top of the first elastic element 231. The slider 232 is slidably connected to the inner wall of the cylinder 23, and a pressure rod 233 is fixedly installed at the top of the slider 232. When the lower mold 1 and the upper mold 11 are closed, the connecting block 21 will push the pressure rod 233, causing the slider 232 to slide inside the cylinder 23, which can quickly push out the gas inside the cylinder 23 for subsequent use. After the lower mold 1 and the upper mold 11 are separated, the slider 232 and the pressure rod 233 can be reset by the reset elastic force of the first elastic element 231.

[0018] As one implementation method in this embodiment, such as Figure 4 As shown, an inner support block 291 is fixedly installed on the inner wall of the square tube 29. A second elastic element 292 is fixedly installed at the bottom of the inner support block 291. A movable plate 293 is fixedly installed at the bottom of the second elastic element 292. When the lower mold 1 and the upper mold 11 are closed, the gas inside the cylinder 23 will pass through the air pipe 24 and be transported from above to the inner cavity of the square tube 29. The rapidly flowing gas will push the movable plate 293 downward. The counting rod 294 will trigger the press counter 27 to count once, realizing the function of automatic counting.

[0019] As one implementation method in this embodiment, such as Figure 4 As shown, the movable plate 293 is slidably connected to the inner wall of the square tube 29. A counting rod 294 is fixedly installed at the bottom of the movable plate 293. After the counting rod 294 moves down to perform counting, the movable plate 293 and the counting rod 294 can be driven to move up to reset by the elastic force of the second elastic element 292.

[0020] As one implementation method in this embodiment, such as Figure 5 As shown, the prompting mechanism 3 includes a hollow column 31, which is fixedly installed on the top of the mounting base 25. An inner column 32 is detachably connected to the inner cavity of the hollow column 31. A positioning bolt 33 is threadedly connected to the outer wall of the hollow column 31. The threaded end of the positioning bolt 33 is in movable contact with the outer wall of the inner column 32. The user can adjust the orientation of the front of the box 34 for easy observation. When adjusting, loosen the positioning bolt 33, then rotate the inner column 32 in the inner cavity of the hollow column 31. After adjustment, tighten the positioning bolt 33.

[0021] As one implementation method in this embodiment, such as Figure 5 As shown, a square box 34 is fixedly installed on the top of the inner column 32. The number of square boxes 34 is set to ten. The design of having ten square boxes 34 makes it convenient for users to roughly understand the number of times.

[0022] As one implementation method in this embodiment, such as Figure 5 As shown, a warning light 35 is fixedly installed on the bottom of the inner wall of the square box 34. A light-transmitting sheet 36 is fixedly installed on the inner wall of the square box 34 near the front. After the warning light 35 is activated, it can emit light through the light-transmitting sheet 36 to indicate the number of uses to nearby users. The data counted by the press counter 27 is fed back to the controller 26, which will control the corresponding number of warning lights 35 to turn on and off. For example, if the mold needs maintenance after 5000 uses, and it has been used 4000 times, the controller 26 will control two warning lights 35 to work, so that users can roughly understand the number of uses. It is worth noting that the controller 26, press counter 27, and warning lights 35 in this solution are technologies in the field. The equipment available to technicians in the market has not undergone structural modifications as described in this paper. Therefore, those skilled in the art are familiar with its working principles based on their professional knowledge and can apply it proficiently. Thus, this paper will not elaborate on it further. Furthermore, this solution aims to protect the physical structure, but does not provide protection for the circuit and software control. The proposed processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not seek protection for the algorithm and circuit technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0023] Working principle: During use, the lower mold 1 and the upper mold 11 are closed, and then injection molding is performed through the injection port 12. After cooling, the mold is separated to obtain the automotive water chamber product. When the lower mold 1 and the upper mold 11 are closed, the connecting block 21 will push the pressure rod 233, causing the slider 232 to slide inside the cylinder 23, which can quickly push the gas inside the cylinder 23 out. The gas inside the cylinder 23 will pass through the air pipe 24 and be transported from above to the inner cavity of the square cylinder 29. The rapidly flowing gas will push the moving plate 293 downward. The counting rod 294 will trigger the press counter 27 to count once, realizing the automatic counting function. The count data of the press counter 27 will be fed back to the controller 26, and the controller 26 will control the corresponding number of warning lights 35 to turn on and off, so that the user can roughly understand the count.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
