Description

Technical Field

[0001] This utility model relates to the field of processing mold technology, and in particular to a welding mold for processing automotive parts. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts, among which the intake sensor requires the small resistor inside to be soldered during processing.

[0003] Currently, resistance welding of the internal components of an intake sensor is generally performed using an automatic welding machine or a handheld welding machine. Both of these welding methods require the use of a welding mold to position the resistor and the housing of the intake sensor. However, existing welding molds typically only use a single-direction positioning structure to limit the housing of the intake sensor, resulting in low stability. Therefore, a welding mold that can position both sides of the housing of the intake sensor is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a welding mold for processing automotive parts, so as to solve the problem mentioned in the background art: common welding molds generally limit the housing of the air intake sensor only through a positioning structure in a single direction, resulting in low stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A welding mold for processing automotive parts, comprising a mold plate and a positioning base plate. The mold plate is placed on the upper surface of the positioning base plate. A material placement groove is provided on one side of the upper surface of the mold plate, and a limiting groove is provided at the center of the upper surface of the mold plate. The limiting groove communicates with the material placement groove. A connecting guide rod is inserted into one side of the inner wall of the limiting groove. One end of the connecting guide rod is fixedly connected to a limiting connecting plate. A limiting spring is connected between the limiting connecting plate and the inner wall of the limiting groove. A supporting connecting plate is fixedly connected between the bottom of the inner wall of the material placement groove. Two guide grooves are provided on the upper surface of the supporting connecting plate. Guide sliders are slidably connected inside the two guide grooves. Push screws are threadedly connected to both sides of the mold plate. One end of each push screw extends into the interior of the material placement groove and contacts the guide slider in the opposite position. The other end of each push screw is fixedly connected to... The mold plate is equipped with an adjusting handle. Two connecting sleeves are fixedly connected to one side of the upper surface of the mold plate, and a positioning magnetic block is fixedly connected to the other side of the upper surface of the mold plate. A support crossbar is inserted between the two connecting sleeves. A limit plate is fixedly connected to one side of the support crossbar, and a positioning magnetic strip is fixedly connected to one end of the limit plate. The positioning magnetic strip is attracted to the positioning magnetic block. A positioning block is fixedly connected to the center of the lower surface of the limit plate, and the positioning block is located directly above the support plate. The purpose of this arrangement is as follows: by setting a limit spring to push the limit plate to reset, the limit plate presses and positions one end of the air intake sensor housing. Rotating the adjusting handle causes the push screw to move inward to the mold plate. The push screw pushes the guide slider to position both sides of the air intake sensor housing. Flipping the limit plate causes the positioning magnetic strip to attract and connect with the positioning magnetic block. The positioning block on the lower surface of the limit plate presses and positions the resistor to be welded at the center of the air intake sensor, facilitating welding.

[0006] Preferably, a mounting sleeve is fixedly connected to one side of the mold plate, and an electric telescopic rod is fixedly installed on the top of one side of the mounting sleeve.

[0007] Preferably, the output end of the electric telescopic rod is fixedly connected to a positioning plate, and one side of the positioning plate is directly opposite one side of the mold plate.

[0008] Preferably, a first barrier plate is fixedly connected to one side of the upper surface of the positioning base plate.

[0009] Preferably, a second barrier plate is fixedly connected to the other side of the upper surface of the positioning base plate.

[0010] Preferably, a micro switch is fixedly installed at the center of one side of the first barrier plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] (1) This device pushes the limiting plate to reset by the limiting spring. The limiting plate presses and positions one end of the air intake sensor housing. Rotating the adjusting handle moves the push screw to the inside of the mold plate. The push screw pushes the guide slider to position both sides of the air intake sensor housing. Flipping the limiting pressure plate makes the positioning magnetic strip and the positioning magnetic block adsorb and connect. The positioning block on the lower surface of the limiting pressure plate presses and positions the resistor to be welded at the center of the air intake sensor, which facilitates welding. This solves the problem that common welding molds generally limit the air intake sensor housing by a single-direction positioning structure, resulting in low stability.

[0013] (2) In order to avoid the mold plate shifting during the welding process, the mold plate is initially limited by the first and second barrier plates, so that the mold plate contacts the micro switch, the micro switch opens the electric telescopic rod, and the electric telescopic rod pushes the positioning pressure plate to position the mold plate.

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.

[0020] This utility model provides, for example Figure 1-4The welding mold for processing automotive parts shown includes a mold plate 1 and a positioning base plate 2. The mold plate 1 is placed on the upper surface of the positioning base plate 2. A material placement groove 3 is provided on one side of the upper surface of the mold plate 1. A limiting groove is provided at the center of the upper surface of the mold plate 1, and the limiting groove communicates with the material placement groove 3. A connecting guide rod 5 is inserted into one side of the inner wall of the limiting groove. A limiting connecting plate 4 is fixedly connected to one end of the connecting guide rod 5. A limiting spring 6 is connected between the limiting connecting plate 4 and the inner wall of the limiting groove. A supporting connecting plate 7 is fixedly connected between the bottom of the inner wall of the material placement groove 3. Two guide grooves 9 are provided on the upper surface of the supporting connecting plate 7. Guide sliders 10 are slidably connected inside the two guide grooves 9. Both sides of the mold plate 1 are threaded with push screws. Each push screw 8 has one end extending into the material passage 3 and contacting the guide slider 10 directly opposite it. The other end of each push screw 8 is fixedly connected to an adjusting handle 17. Two connecting sleeves 11 are fixedly connected to one side of the upper surface of the mold plate 1, and a positioning magnetic block 14 is fixedly connected to the other side of the upper surface of the mold plate 1. A support crossbar 12 is inserted between the two connecting sleeves 11. A limiting pressure plate 13 is fixedly connected to one side of the support crossbar 12. A positioning magnetic strip 15 is fixedly connected to one end of the limiting pressure plate 13. The positioning magnetic strip 15 is attracted to the positioning magnetic block 14. A positioning block 16 is fixedly connected to the center of the lower surface of the limiting pressure plate 13. The positioning block 16 is located directly above the support connecting plate 7.

[0021] like Figure 4 The diagram shows a welding mold for processing automotive parts. A mounting sleeve 18 is fixedly connected to one side of the mold plate 1. An electric telescopic rod 19 is fixedly installed on the top of one side of the mounting sleeve 18. A positioning pressure plate 20 is fixedly connected to the output end of the electric telescopic rod 19. One side of the positioning pressure plate 20 is directly opposite to one side of the mold plate 1.

[0022] The working principle of this utility model is as follows: Pulling the limiting plate 4 causes the limiting spring 6 to retract, separating the positioning magnetic block 14 from the positioning magnetic strip 15. The limiting pressure plate 13 is flipped, and the adjusting handle 17 is rotated to move the pushing screw 8 outwards from the mold plate 1. The air intake sensor of the resistor to be welded is placed in the material placement groove 3. The limiting spring 6 pushes the limiting plate 4 to reset, and the limiting plate 4 presses and positions one end of the air intake sensor housing. Rotating the adjusting handle 17 moves the pushing screw 8 inwards from the mold plate 1, and the pushing screw 8 pushes the guide slider 10 to position both ends of the air intake sensor housing. Positioning is performed on the side, and the limiting pressure plate 13 is flipped so that the positioning magnetic strip 15 and the positioning magnetic block 14 are attracted and connected. The positioning block 16 on the lower surface of the limiting pressure plate 13 presses and positions the resistor to be welded at the center of the air intake sensor, which facilitates welding. When welding with an automatic welding machine, in order to prevent the mold plate 1 from shifting during the welding process, the mold plate 1 is placed between the first barrier plate 21 and the second barrier plate 22, so that the mold plate 1 contacts the micro switch 23. The micro switch 23 opens the electric telescopic rod 19, and the electric telescopic rod 19 pushes the positioning pressure plate 20 to position the mold plate 1.
