Description

Technical Field

[0001] The invention belongs to the technical field of molds, and in particular relates to an injection mold for an 8PIN automobile connector. Background Art

[0002] The injection mold of the 8PIN automotive connector plays a vital role in automobile manufacturing. As the core tool for producing connectors, the design and manufacturing quality of the injection mold directly affects the performance, cost and production efficiency of the connector. Compared with the traditional manual production method, the injection mold can produce a large number of standardized products in a short time. The injection molding has a high degree of automation, which reduces manual intervention and operating errors and improves production efficiency. Through precise design and manufacturing, the injection mold can ensure that the size, shape and performance of each connector meet the design standards. This consistency not only helps to ensure the reliability and stability of the connector, but also reduces the quality problems caused by product inconsistency, thereby improving the quality level of the whole vehicle. The use of injection molds can reduce material waste and improve material utilization. The high production efficiency and low process cost in the injection molding process also help to reduce the production cost of a single product. The injection mold can produce high-precision connector parts to meet strict design standards. Through precise mold design and processing, the complex structure and fine features inside the connector can be realized, ensuring that the connector can work stably in practical applications and can work well with other components. Therefore, the injection mold of the 8PIN automotive connector is of great significance.

[0003] When the existing 8PIN automotive connector is manufactured by injection molding, the eight pins are generally positioned by fitting the pin sockets, and then injection molding is performed in the mold. In actual injection molding, the pin positioning socket itself has a very small aperture. When some fine dust particles or debris enter the pin positioning socket, it is difficult to clean it. If it is not cleaned in time, it is easy to affect the accurate positioning of the pins. In order to solve the above problems, an injection mold for an 8PIN automotive connector is provided. Summary of the invention

[0004] The purpose of the present invention is to provide an injection mold for an 8-pin automobile connector in order to solve the above-mentioned problem.

[0005] The technical solution adopted by the present invention is as follows: an injection mold for an 8PIN automotive connector, comprising:

[0006] The 8PIN automotive connector uses an upper injection mold and a lower injection mold. The upper portion of the lower injection mold is provided with four injection mold grooves adapted for the 8PIN automotive connector. The bottom of the injection mold groove is provided with eight metal pin sockets. The bottom of the metal pin sockets is provided with air outlets. The interior of the lower injection mold is provided with two air inlet channels, and the air outlets are connected to the air inlet channels.

[0007] Furthermore, the air inlet channel passes through the lower injection mold body, and one end of the air inlet channel is threadedly sealed and connected with a plug.

[0008] Furthermore, the other end of the air intake passage is threadedly sealed and connected to an air intake joint, a branch air intake pipe is fixedly connected to the air intake joint, the air intake end of the branch air intake pipe is fixedly connected to a main air supply pipe, and the main air supply pipe is connected to the factory compressed air supply pipe.

[0009] Furthermore, a solenoid valve is provided on the main air supply pipe.

[0010] Furthermore, an air filter is installed on the main air supply pipe, and the air filter includes a filter cartridge and a filter screen. The filter cartridge is installed on the main air supply pipe, and the filter screen is fixedly installed in the filter cartridge.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In the present invention, after each injection molding of the mold is completed, the solenoid valve is controlled to open, so that the main air supply pipe introduces compressed air into the branch air inlet pipe, and the compressed air enters the air inlet channel, thereby supplying air to the air inlet channel, and then the compressed air will be ejected from the air outlet, so that the dust or tiny debris in the metal pin socket is ejected by compressed air, so as to facilitate the cleaning of the metal pin socket and prevent dust or tiny debris from entering and affecting the insertion and accurate positioning of the metal pin.

[0013] 2. In the present invention, the filter screen in the air filter can be used to filter the dust in the compressed air, thereby preventing it from entering the air inlet channel and blocking the air outlet, thereby protecting the clean air channel in the mold and preventing impurities in the compressed air from entering the mold.

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The following will be combined Figure 1-Figure 3 An injection mold for an 8-pin automobile connector according to an embodiment of the present invention is described in detail.

[0020] An injection mold for an 8PIN automotive connector provided by an embodiment of the present invention is provided with reference to Figures 1 to 3 As shown, including:

[0021] The 8PIN automotive connector uses an upper injection mold 1 and a lower injection mold 2. The upper portion of the lower injection mold 2 is provided with four injection mold grooves 3 adapted to the 8PIN automotive connector. The bottom of the injection mold groove 3 is provided with eight metal pin sockets 4. The upper injection mold 1 and the lower injection mold 2 of this structure constitute an injection mold for the 8PIN automotive connector. During injection molding, the eight metal pins of the 8PIN automotive connector are correspondingly inserted into the metal pin sockets 4 in the injection mold groove 3, thereby positioning and fixing the metal pin positions and ensuring the stability of the metal pin positions during injection molding.

[0022] In some embodiments, an air outlet 5 is provided at the bottom of the metal pin socket 4, and two air inlet channels 6 are provided inside the lower injection mold 2. The air outlet 5 is connected to the air inlet channel 6. In this structure, after the injection molding is completed, compressed air can be introduced into the air inlet channel 6, and then the compressed air will be ejected from the air outlet 5, so that the dust or tiny debris in the metal pin socket 4 can be ejected by the compressed air, so as to facilitate the cleaning of the metal pin socket 4 and prevent dust or tiny debris from entering and affecting the insertion and accurate positioning of the metal pin.

[0023] In some embodiments, the other end of the air intake channel 6 is threadedly sealed and connected to an air intake joint 8, to which a branch air intake pipe 9 is fixedly connected, and the air intake end of the branch air intake pipe 9 is fixedly connected to a main air supply pipe 10, which is connected to the factory compressed air supply pipe. In this structure, the main air supply pipe 10 introduces compressed air into the branch air intake pipe 9, so that the compression hole enters into the air intake channel 6, thereby supplying air to the air intake channel 6.

[0024] In some embodiments, a solenoid valve 11 is provided on the main gas supply pipe 10. This structure uses the solenoid valve 11 to control the opening and closing of the main gas supply pipe 10, thereby controlling the gas supply.

[0025] In some embodiments, an air filter 12 is installed on the main air supply pipe 10. The air filter includes a filter cartridge 13 and a filter screen 14. The filter cartridge is installed on the main air supply pipe 10, and the filter screen 14 is fixedly installed in the filter cartridge 13. In this structure, the filter screen 14 in the air filter 12 can filter the dust in the compressed air, thereby preventing it from entering the air inlet channel 6 and clogging the air outlet 5.

[0026] In some embodiments, the air inlet channel 6 passes through the lower injection mold 2, and one end of the air inlet channel 6 is threadedly sealed with a plug 7. This structure uses the plug 7 to block one end of the air inlet channel 6 to prevent air from flowing out. At the same time, when the air inlet channel 6 needs to be cleaned, it is only necessary to unscrew the plug 7, and then the air inlet channel 6 can be conveniently cleaned.

[0027] In some embodiments, after each injection molding of the mold is completed, the solenoid valve 11 is controlled to open, so that the main air supply pipe 10 introduces compressed air into the branch air inlet pipe 9, and the compressed air is filtered through the filter 14 in the air filter 12 and then enters the branch air inlet pipe 9, so that the clean compressed air enters the air inlet channel 6, thereby supplying air to the air inlet channel 6, and then the compressed air is ejected from the air outlet 5, so that the dust or tiny debris in the metal pin socket 4 is ejected by compressed air, thereby facilitating the cleaning of the metal pin socket 4 and preventing dust or tiny debris from entering and affecting the insertion and accurate positioning of the metal pin.
