Description

Technical Field

[0001] This utility model relates to the field of automotive switch technology, specifically to a hole-opening device for the production of plastic parts for automotive switches. Background Technology

[0002] Automotive switches refer to various control switches installed inside automobiles to control various functions and equipment of the vehicle. Automotive switches are also plastic products. During the production of plastic parts, a drilling device is required. The drilling device is a special equipment that processes holes of various shapes and sizes on the parts, which can improve production efficiency.

[0003] Currently, the hole-opening device still has some shortcomings, such as low hole-opening efficiency.

[0004] To overcome the problem of low efficiency in drilling holes in plastic parts, a Chinese patent (publication number: CN219027760U) discloses an automatic drilling device for plastic septic tanks. Through mechanical operation, it not only frees up manpower, but also sets up two drilling devices that can drill both the inlet and outlet holes in one operation, eliminating the need for a second drilling operation and greatly improving the efficiency of drilling holes in septic tanks.

[0005] However, the current hole-opening device still has some shortcomings. The hole-opening of the plastic parts in the above document will generate heat. If multiple holes need to be opened, it is easy for some parts of the plastic parts to melt slightly and stick to the base. In addition, the debris generated by the switch will be attracted to the plastic parts under the action of static electricity, which may affect the accuracy of the hole opening of the device. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to provide a hole-opening device for the production of plastic parts for automotive switches, so as to solve the problems of low cooling efficiency of plastic parts in the hole-opening device proposed in the background art, and the plastic parts being easy to stick due to high temperature after processing, which makes it inconvenient to unload the material.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hole-opening device for producing plastic parts for automotive switches, comprising a base, wherein the base has four holes connected inside:

[0008] The base has a rotating groove inside, and two manual air pumps are installed inside the rotating groove. A large gear rod is rotatably connected through the manual air pump, and the end of the large gear rod is fixed to the impeller inside the manual air pump. The air inlet of the manual air pump is connected through the base. The base is equipped with an air blowing mechanism to improve the cooling efficiency of the plastic parts.

[0009] Furthermore, the air blowing mechanism includes a motor installed inside the rotating slot, and a small gear rod is fixed to the output end of the motor, which meshes with the side of a large gear rod.

[0010] Furthermore, the manual air pump outlet is connected to a first air distribution pipe, and both ends of the first air distribution pipe are connected to second air distribution pipes, with the ends of the second air distribution pipes being connected to the hole.

[0011] Furthermore, the base is also equipped with an ejection mechanism to improve the material feeding efficiency of the punching device. The ejection mechanism includes a sliding groove inside the base, and an electric push rod is installed inside the sliding groove.

[0012] Furthermore, a push block is connected to the top of the electric push rod, and a limit block is fixed on the side of the push block. Both the push block and the electric push rod slide inside the sliding groove.

[0013] Furthermore, a top block slides near the top of the push block in the sliding groove, and a pressing block is fixed to the side of the top block. A guide rod is slidably connected through the inner side of the top block, and the guide rod is also slidably connected to the guide groove. A spring is telescopically connected between the guide rod and the guide groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This drilling device for producing plastic parts for automotive switches has a first air distribution pipe that can further divert and discharge air through a second air distribution pipe. The discharged air can blow air onto the processing position of the plastic part, accelerating the heat dissipation efficiency after drilling. Furthermore, the blowing air during the drilling process can reduce the adhesion of plastic debris, thereby indirectly improving the drilling accuracy. When the top block moves to the bottom of the plastic part, it can be squeezed. After being squeezed, the plastic part can be separated from the base, preventing the plastic part from sticking to the surface of the base and affecting the material feeding efficiency.

[0016] 2. It is equipped with a pinion gear and a large gear. The pinion gear and the large gear have different sizes and gear ratios, which makes it easier to operate and reduces the power consumption required by the motor. In addition, the large gear can drive two large gears to rotate at the same time, which reduces production costs.

[0017] 3. A second air distribution pipe is provided, which can blow air onto the processed area of ​​the plastic part, reducing the impact of processing debris and improving the cooling efficiency of the plastic part.

[0018] 4. Equipped with a top block, which can move laterally and longitudinally via a guide rod, providing multiple movement modes and facilitating the ejection and unloading of plastic parts. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides the following technical solution to address the problem of low cooling efficiency of plastic parts in a punching device: A blowing mechanism is disclosed, comprising a base 1 with four holes 2 inside; a rotating groove 102 is provided inside the base 1, and two manual air pumps 103 are installed inside the rotating groove 102. A large gear rod 104 is rotatably connected through the manual air pump 103, and the end of the large gear rod 104 is fixed to an impeller inside the manual air pump 103. The air inlet of 3 is connected to the inside of the base 1. The base 1 is equipped with an air blowing mechanism to improve the cooling efficiency of the plastic parts. The air blowing mechanism includes a motor 101 installed inside the rotating slot 102. A small gear rod 105 is fixed to the output end of the motor 101. The small gear rod 105 is meshed with the side of the large gear rod 104. The air outlet of the manual air pump 103 is connected to the first air distribution pipe 106. Both ends of the first air distribution pipe 106 are connected to the second air distribution pipe 107. The port of the second air distribution pipe 107 is connected to the hole 2.

[0028] During the production of plastic parts, the product is placed on the upper surface of the base 1 for drilling. Drilling debris falls through the holes 2 and is collected elsewhere. During the drilling process, the motor 101 can be started to rotate the small gear 105. When the small gear 105 rotates, it meshes with and drives the large gear 104 to rotate. When the large gear 104 rotates, it can be rotated by the manual air pump 103. The rotation of the large gear 104 drives the impeller inside the manual air pump 103 to rotate, and the impeller's rotation allows air to enter through the manual air pump 103. The air is drawn in through the mouth and expelled through the air outlet. When the manual air pump 103 is venting, the airflow can be split into two streams through the air distribution pipe 106. The air distribution pipe 106 can then be split and discharged again through the air distribution pipe 2 107. The discharged gas can blow air onto the processing position of the plastic part, which accelerates the heat dissipation efficiency after drilling. In addition, the blowing during the drilling process can reduce the adhesion of plastic debris, thereby improving the drilling accuracy. Continuous blowing can also prevent the plastic part from melting and adhering to the surface of the base 1 after processing, which improves the convenience of the drilling device.

[0029] Example 2, as follows Figure 2 , Figure 3 , Figure 5 and Figure 6The present invention provides the following technical solution: In order to solve the problem that plastic parts are easily stuck due to high temperature after processing, making it inconvenient to unload, an ejection mechanism is disclosed: The base 1 is also provided with an ejection mechanism to improve the unloading efficiency of the punching device. The ejection mechanism includes a sliding groove 201 opened inside the base 1. An electric push rod 202 is installed inside the sliding groove 201. A push block 203 is connected to the top of the electric push rod 202. A limit block 204 is fixed on the side of the push block 203. The push block 203 and the electric push rod 202 slide inside the sliding groove 201. A top block 206 slides near the top of the push block 203 in the sliding groove 201. An extrusion block 205 is fixed on the side of the top block 206. A guide rod 207 is slidably connected through the inner side of the top block 206. The guide rod 207 and the guide groove 208 are also slidably connected. A spring is telescopically connected between the guide rod 207 and the guide groove 208.

[0030] After the drilling device completes its processing, the electric actuator 202 can be activated. When the electric actuator 202 is activated, it pushes the push block 203 upward. When the push block 203 moves, it can drive the limit block 204 to move. When the push block 203 moves, its inclined surface can squeeze the bottom of the extrusion block 205. When the extrusion block 205 is squeezed, it can drive the top block 206 to move. At this time, the limit block 204 and the push block 203 can slide upward inside the sliding groove 201, while the top block 206 and the extrusion block 205 slide to the side. When the top block 206 slides, it can pull... The guide rod 207 moves and slides through the guide groove 208. When the guide rod 207 slides, it can stretch the spring. When the top block 206 slides out of the sliding groove 201, the push block 203 can push the extrusion block 205 to move upward. When the extrusion block 205 moves upward, it can drive the top block 206 to move upward. When the top block 206 moves to the bottom of the plastic part, it can be extruded. After the plastic part is extruded, it can be separated from the base 1, preventing the plastic part from sticking to the surface of the base 1 and affecting the material feeding efficiency, thus improving the drilling efficiency of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
