Description

Technical Field

[0001] The present invention relates to the technical field of molds, and particularly relates to a precision mold for automotive parts with an in-mold tapping cooling structure. Background Art

[0002] Currently, in the entire stamping industry, the in-mold tapping cooling system has been plaguing manufacturers, especially in automotive parts manufacturers. Now all automotive parts are made of high-strength steel plates or even ultra-high-strength steel plates. There are some tapping products in the rotating shafts and door lock systems of automotive parts. Now, in order to improve production efficiency, most products have changed from traditional single-process molds to progressive die production. Progressive die production adds in-mold tapping equipment to complete product hole flanging and tapping together in the mold. However, when the product enters the tapping process after hole flanging, problems such as tooth burning of the tooth hole, excessive temperature of the tap, and accelerated wear often occur, resulting in the product's torque and thrust not meeting the requirements, ultimately bringing immeasurable economic losses to the stamping manufacturer at the client side.

In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0019] A precision mold for automobile parts with an in-mold tapping cooling structure, please refer to Figures 1-7 , including a base 1 and a part body 2. A cooling plate 3, a clamping mechanism 4, a cleaning mechanism 5, a tapping mechanism 6 and a controller 7 are fixedly installed on the base 1.

[0023] Through the above technical solution, in this experimental novelty, the first motor 43 drives the clamping plate 45 to move towards the cooling plate 3 through the rotating shaft 42 and the threaded rod 44, so that the clamping column 46 squeezes the part body 2 placed between the cooling plate 3 and the clamping mechanism 4, firmly fixing the part body 2 to the base 1, facilitating the subsequent tapping operation of the tapping mechanism 6 on the part body 2.

The driving shaft 63 is rotatably connected to the fixed seat 61 through a bearing. The driving wheel 64 is fixedly installed at the free end of the driving shaft 63 and is connected to the driven wheel 66 through the conveyor belt 65.

The lead screw 67 is rotatably connected to the fixed seat 61 through a bearing, and the lead screw 67 is used to drive the moving plate 68 to move up and down. The moving plate 68 is threadedly connected to the lead screw 67 and is used to drive the tapping structure 69 to descend to the position of the part body 2 and perform tapping operations. Sliders 681 are provided on both sides of the moving plate 68, and sliding grooves 611 corresponding to and matching the sliders 681 are formed on the fixed seat 61. The lead screw 67 drives the moving plate 68 to move up and down along the sliding grooves 611 to realize the tapping operation of the tapping structure 69 on the part body 2.

[0027] Through the above technical solution, in this experimental novelty, the second motor 62 drives the driven wheel 66 to rotate through the driving shaft 63, the driving wheel 64, and the conveyor belt 65, thereby driving the lead screw 67 to rotate. The lead screw 67 drives the moving plate 68 to move up and down along the sliding grooves 611 to realize the tapping operation of the tapping structure 69 on the part body 2. The cooperation between the sliders 681 and the sliding grooves 611 maintains the stability of the moving plate 68 during the lifting process and prevents the moving plate 68 from getting stuck, thereby affecting the tapping operation of the tapping structure 69.

[0028] In some examples, referring to Figures 1-7 As shown, the cooling mechanism includes a water inlet pipe 31, a water pump 32, a water pipe 33, and a movable nozzle 34, where: The water inlet pipe 31 is inserted into the cooling plate 3, one end is communicated with a water source, and the other end is connected to the water pump 32. The water pipe 33 is arranged inside the cooling plate 3 and is used to transmit the water input by the water pump 32. The movable nozzle 34 is arranged outside the cooling plate 3 and can change the spraying direction.

[0029] Through the above technical solution, in this experimental novelty, while the tapping structure 69 is performing tapping operations, the water pump 32 drives the water flow to enter from the water inlet pipe 31, and after being transmitted through the water pipe 33, it sprays out from the movable nozzle 34 to cool the tapping part, preventing the occurrence of situations where the product's torque and thrust cannot meet the requirements due to tooth hole burning, too high a temperature of the tap, and accelerated wear. The movable nozzle 34 can change the direction, thereby cooling the tapping parts in different directions and improving the applicability.

[0030] In some examples, referring to Figures 1-7As shown in the figure, the cleaning mechanism 5 is located on the side of the part body 2 and includes a cylinder 51, a telescopic rod 52, a cleaning plate 53 and a brush 54, where: The cylinder 51 is arranged in the base 1 and drives the cleaning plate 53 through the telescopic rod 52; The cleaning plate 53 is fixedly installed at the free end of the telescopic rod 52 and is used to drive the brush 54; The brush 54 is fixedly installed on the bottom surface of the cleaning plate 53 and is used to clean the upper surface of the part body 2 after tapping; A second limiting rod 55 is provided on the side of the cleaning plate 53 close to the cylinder 51, and a second limiting hole 14 corresponding to and matching the second limiting rod 55 is provided on the base 1.

The air inlet 39 is used to introduce gas into the ventilation chamber 35.

[0033] Through the above technical solution, after the cleaning mechanism 5 in the present experimental novelty finishes cleaning, the fan 38 blows out high-speed air flow through the air inlet 39 to dry the water stains on the upper surface of the part body 2, which is convenient for subsequent operations on the part body 2; The filter screen 37 can effectively prevent debris from entering the ventilation chamber 35 and blocking the ventilation chamber 35, affecting the blowing out of the high-speed air flow.

[0034] The specific working process is as follows: After placing the part body 2 between the cooling plate 3 and the clamping mechanism 4, the first motor 43 is started through the controller 7. The first motor 43 drives the clamping plate 45 to move towards the cooling plate 3 through the rotating shaft 42 and the threaded rod 44, so that the clamping column 46 squeezes the part body 2, firmly fixing the part body 2 to the base 1. Then, the second motor 62 is started through the controller 7. The second motor 62 drives the driven wheel 66 to rotate through the driving shaft 63, the driving wheel 64 and the conveyor belt 65, thereby driving the lead screw 67 to rotate. The lead screw 67 drives the moving plate 68 to lift along the sliding groove 611 to realize the tapping operation of the tapping structure 69 on the part body 2. During the tapping operation, the water pump 32 is started through the controller 7. The water pump 32 drives the water flow to enter from the water inlet pipe 31 and, after being transmitted through the water pipe 33, is sprayed out from the movable nozzle 34 to cool the tapping part. After the tapping is completed, the cylinder 51 is started through the controller 7. The cylinder 51 drives the cleaning plate 53 to move through the telescopic rod 52. The cleaning plate 53 drives the brush 54 to clean the part body 2 along the surface of the part body 2, pushing the sundries into the waste water cavity 11. After the cleaning is completed, the fan 38 is started through the controller 7. The fan 38 blows out the high-speed air flow through the air inlet 39 to dry the water stains on the upper surface of the part body 2, facilitating the subsequent operation on the part body 2.

And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
