[0002] In the design of injection molds for automotive parts, the venting system is crucial to ensuring the smooth flow of molten plastic during injection and avoiding defects. An efficient venting device helps reduce the generation of gas, bubbles, and defects, thereby improving the molding quality of the mold.

[0003] In traditional devices, without the blocking function driven by the lifting component, the exhaust port may remain exposed, resulting in unstable exhaust performance or even uneven exhaust.

[0004] Secondly, without a quick-installation design, the motor and related components may require lengthy manual installation or disassembly. This not only increases operational complexity but also wastes a significant amount of production time.

[0005] Finally, without a locking mechanism, the motor and mounting bracket may loosen or shift during use due to vibration or external forces, affecting the normal operation of the exhaust device and even causing equipment damage. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a high-efficiency venting device for injection molds of automotive parts, thereby solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency venting device for injection molds of automotive parts, comprising a main body, a closing mechanism, an installation mechanism, and a locking mechanism.

[0010] In a further preferred embodiment, the main body is provided with a sliding groove, and the driven member is provided with a first screw, which is connected to the lifting member to facilitate the forming of the parts.

[0011] In a further preferred embodiment, the lifting component is provided with a first threaded hole and a limiting block, the limiting block being slidably connected to the main body, and the first threaded hole being engaged with a first screw to facilitate the sliding of the lifting frame.

[0012] In a further preferred embodiment, the main body is provided with a limiting groove, the lifting component is provided with a baffle, the baffle is provided with a limiting block, and the limiting block is slidably connected to the limiting groove to facilitate the stable lifting of the lifting component.

This ensures that air and gas are not allowed to enter the mold cavity when the mold is closed, and that gas can be smoothly discharged when the mold is opened. This avoids the generation of bubbles and pores, and helps to improve the molding quality of the parts.

[0016] In this utility model, by setting up an installation mechanism, the motor can be quickly installed onto the main body through the cooperation of the mounting frame and the motor, thus simplifying the assembly process of the equipment.

[0017] By setting a locking mechanism, the locking mechanism of this device can ensure the stability of the motor and the mounting bracket during use through the cooperation of the locking parts and the drive rod, and avoid failures or vibrations caused by the motor being loose or the mounting bracket not being properly fixed. This ensures the stability of the exhaust device during operation and avoids performance fluctuations caused by instability. Attached Figure Description

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-5 A high-efficiency venting device for injection molds of automotive parts includes a main body 1, a closing mechanism, an installation mechanism, and a locking mechanism. The closing mechanism includes an inner mold 2 and a driven member 3. The inner mold 2 is fixedly installed inside the main body 1. The driven member 3 is installed on the main body 1 and rotatably connected to the main body 1. A lifting member 4 is installed inside the main body 1. The lifting member 4 is respectively connected to the driven member 3 and slidably connected to the main body 1. The installation mechanism includes a mounting frame 5 and a motor 6. The mounting frame 5 is installed on the main body 1 and connected to the main body 1. The motor 6 is fixedly installed on the mounting frame 5 and connected to the driven member 3.

[0023] In this embodiment, the closing mechanism includes an inner mold 2 and a driven member 3. During use, after the inner mold 2 inside the main body 1 comes into contact with the plastic, the motor 6 installed on the main body 1 starts to drive, so that the driven member 3 can rotate on the main body 1. The roller 11 slides in the sliding groove 12, and the first screw 13 on the driven member 3 is connected to the first threaded hole 14 on the lifting member 4. The lifting member 4 is stably raised and lowered on the main body 1 under the sliding action of the limiting block 15 and the limiting groove 16. Then, the baffle 17 on the lifting member 4 is connected to the main body 1. When the lifting member 4 is raised and lowered inside the main body 1, the air in the inner mold 2 flows through the limiting hole to the flow hole 18 on the driven member 3 to complete the gas discharge.

[0024] In this embodiment, the installation mechanism includes a mounting bracket 5 and a motor 6. In use, the mounting bracket 5 can be installed on the main body 1. Then, the fitting block 20 on the motor 6 is connected to the fitting hole 19 on the driven member 3, and the locking member 7 is also unlocked in advance. After the mounting bracket 5 is installed, the locking mechanism can be used to fix the position of the mounting bracket 5, thereby fixing the position of the motor 6.

[0025] In this embodiment, the locking mechanism includes a locking member 7 and a drive rod 8. In use, the positioning member 9 can be pulled directly, allowing it to slide on the main body 1 and stretch the spring 25. The positioning member 9 then disengages directly from the positioning hole 24. The drive rod 8 can then be rotated, causing the second screw 23 on the drive rod 8 to engage with the second threaded hole 22 on the locking member 7. This allows the locking member 7 to enter the locking hole 21 of the mounting bracket 5, thereby fixing the position of the mounting bracket 5.

[0026] Example 2

[0027] In summary, during use, the mounting bracket 5 can first be installed onto the main body 1. Then, the fitting block 20 on the motor 6 engages with the fitting hole 19 on the driven member 3, and the locking member 7 is pre-unlocked. After the mounting bracket 5 is installed, a locking mechanism can be used to fix its position, thus fixing the position of the motor 6. During installation, the positioning member 9 can be pulled, allowing it to slide on the main body 1 and stretch the spring 25. The positioning member 9 then disengages from the positioning hole 24. At this point, the drive rod 8 can be rotated, causing the second screw 23 on the drive rod 8 to engage with the second threaded hole 22 on the locking member 7, allowing the locking member 7 to enter the locking hole 21 of the mounting bracket 5, thereby fixing its position. Once the mounting bracket 5 and the motor 6 are fixed on the main body 1... Afterwards, rubber can be injected into the body 1. After the inner mold 2 inside the body 1 comes into contact with the plastic, the motor 6 installed on the body 1 starts to drive, so that the driven member 3 can rotate on the body 1. The roller 11 slides in the sliding groove 12, and the first screw 13 on the driven member 3 is connected to the first threaded hole 14 on the lifting member 4. The lifting member 4 is stably raised and lowered on the body 1 under the sliding action of the limiting block 15 and the limiting groove 16. Then the baffle 17 on the lifting member 4 is connected to the body 1. When the lifting member 4 is raised and lowered inside the body 1, the air in the inner mold 2 flows through the limiting hole to the flow hole 18 on the driven member 3 to complete the gas discharge. After the inner mold 2 comes into contact with the plastic, it transfers heat to the heat sink 10 fixedly connected to the inner mold 2, thereby transferring it to the outside.

[0028] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
