[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a stamping die for an automotive motor housing, including a base 4, a guide structure, a pressure system 201, and a forming system 3 mounted on the base. The forming system 3 includes an upper template 202, a lower template 2, a punch 301, and a die 302. The punch 301 is fixedly connected to the upper template 202, and the die 302 is detachably connected to the lower template 2. A cooling and demolding system 401 is provided at the end of the punch 301. A detection and control system 5 is provided on the base 4, and the detection and control system 5 is controlled and connected to the cooling and demolding system 401.

[0024] This embodiment combines cooling and demolding. The cooling and demolding system 401 enables rapid stamping cooling and shaping, and demolding is achieved through high-pressure gas blowing, significantly improving the production efficiency of stamping dies. The design of the cooling and demolding system 401 allows the die to cool rapidly after forming, thereby shortening the production cycle. The detachable connection between the valve seat 409 and the base 4 makes maintenance and replacement of the cooling module and demolding module more convenient.

[0025] The detection and control system 5 consists of a first positioning sensor 501, a second positioning sensor 502, and a switch sensor. The first positioning sensor 501 is installed on the upper template 202, and the second positioning sensor 502 is installed on the lower template 2. Both the first positioning sensor 501 and the second positioning sensor 502 adopt the inductive working principle. When the upper template 202 and the lower template 2 are pressed against each other by the pressure system 201, the first positioning sensor 501 and the second positioning sensor 502 come into contact with each other and are contacted by the detection probes 503 corresponding to the first positioning sensor 501 and the second positioning sensor 502. After contact, the capacitance value of the sensor will change. The sensor can detect this change and thus determine whether the upper template 202 and the lower template 2 are in the same position, which further improves the processing accuracy during mold operation.

[0026] The switch sensor 504 installed in the lower mold plate 2 detects the distance between the upper mold plate 202 and the lower mold plate 2 through infrared light during the mold operation. When the distance between the two is less than the preset value, the control module controls the start and stop of the cooling air control valve 407 and the high pressure gas control valve 405. The cooling control valve and the switch sensor 504 are controlled synchronously. The control time between the high pressure gas control valve 405 and the switch sensor 504 is delayed by 1 second. The high pressure gas is blown out to assist demolding only after the part has been cooled.

[0027] The cooling and demolding system 401 is located at the bottom of the punch 301. The cooling and demolding system 401 includes a valve seat 409, a cooling module and a demolding module located on the valve seat 409. The valve seat 409 is detachably connected to the base 4. The valve seat 409 is provided with a high-pressure gas control valve 405 and a cooling air control valve 407. The cooling module and the demolding module are connected to the valve seat 409. The punch 301 is provided with a high-pressure gas channel 304 for connecting the demolding module. The cooling module is located on the outside of the punch 301. The demolding module is connected to the high-pressure gas control valve 405 and the cooling module is connected to the cooling air control valve 407.

[0028] In this embodiment, a cooling module and a demolding module are connected via a valve seat 409. Two pipes (one connecting to the demolding module and two connecting to the cooling module) are independently installed within the valve seat 409. Cooling air is supplied through a cooling air inlet 402 and a high-pressure air inlet 404 on the valve seat 409. The cooling module is located on the outside of the punch 301. When the punch 301 and the groove are pressed together, the cooling module blows cooling air through a nozzle 408 onto the molded part, rapidly cooling it. The high-pressure air control valve 405 is connected to a high-pressure air channel 304. After the punch 301 is formed, the molded workpiece is in close contact with the punch 301. High-pressure gas is blown out through the high-pressure air channel 304, causing the molded part to separate from the punch 301 and be demolded.

[0029] Furthermore, the detection and control system 5 includes a first positioning sensor 501, a second positioning sensor 502, and a switch sensor 504. The first positioning sensor is connected to the upper template 202, the second positioning sensor 502 is connected to the lower template 2, the switch sensor 504 has a built-in control module, and the switch sensor 504 is mounted on the base 4. The switch sensor 504 is connected to the high-pressure gas control valve 405 and the cooling air control valve 407 respectively.

[0030] After receiving the infrared signal, the switch sensor 504 controls the opening and closing of the high-pressure gas control valve 405 and the cooling air control valve 407 based on the sensor's feedback signal. The control module of the switch sensor 504 enables automated management, reduces manual intervention, and improves production efficiency. After template alignment, the system can automatically control the opening and closing of the high-pressure gas and cooling air, optimizing the molding process.

[0031] Furthermore, the first positioning sensor 501 and the second positioning sensor 502 are arranged vertically aligned. Both the first positioning sensor 501 and the second positioning sensor 502 are equipped with a detection probe 503. The lower template 2 is provided with a positioning groove and a positioning block 303 disposed on the positioning groove. The second positioning sensor 502 is connected to the positioning block 303.

[0032] The first positioning sensor 501 and the second positioning sensor 502 are vertically aligned to ensure that the relative position of the upper and lower templates 2 can be accurately detected. This ensures the alignment accuracy between the upper and lower templates 2 during the stamping process and avoids forming defects caused by deviations. The lower template 2 is provided with a positioning groove, and the positioning block 303 is placed in the positioning groove to ensure that the second positioning sensor 502 can accurately correspond to the position of the first positioning sensor 501 during installation.

[0033] Furthermore, the base 4 is connected to a guide structure, which includes a fixed plate 1 and several guide rods. The guide rods pass through the fixed plate 1 and connect to the upper template 202. The guide rods are also connected to a pressure system 201, which is located between the upper template 202 and the lower template 2. The guide rods pass through the fixed plate 1 and connect to the upper template 202, forming a stable guide system 101. The design of the guide rods ensures that the upper template 202 can move along a predetermined trajectory during movement, reducing lateral movement and tilting, and ensuring the precise positioning of the upper template 202.

[0034] Furthermore, the pressure system 201 includes several piston rods and hydraulic cylinders connecting the piston rods. Springs are fitted onto the piston rods, and the guide rod is coaxially connected to the hydraulic cylinder. The pressure system 201 is disposed between the upper mold plate 202 and the lower mold plate 2, and is used to apply pressure to achieve molding or pressing operations. The pressure system 201 can employ hydraulic methods to achieve material molding or pressing.

[0035] Furthermore, the valve seat 409 contains two pipes: pipe one connects to the high-pressure gas control valve 405, and pipe two connects to the cooling air control valve 407. One side of the valve seat 409 also has a cooling air inlet 402 connecting to pipe one and a high-pressure gas inlet 404 connecting to pipe two. The pipes inside the valve seat 409 are used to connect the high-pressure gas control valve 405 and the cooling air control valve 407, respectively. The pipes connecting the high-pressure gas control valve 405 and the cooling air control valve 407 allow for effective distribution and control of gas and cooling air through the valve seat 409.

[0036] Furthermore, the cooling module includes a cooling air delivery duct 406 and a nozzle 408 connected to the cooling air delivery duct 406. The cooling air delivery duct 406 is connected to a cooling air control valve 407. One side of the valve seat 409 is provided with a cooling air inlet 402 connecting to pipe one and a high-pressure gas inlet 404 connecting to pipe two. Cooling air and high-pressure gas can be introduced into the corresponding pipes as needed, ensuring smooth flow of gas and air. The nozzle 408 blows cold air towards the molded part and evenly distributes the cooling air onto the surface of the molded part for rapid cooling.

[0037] Furthermore, the demolding module includes a high-pressure gas delivery conduit 403, which is sealed to two high-pressure gas channels 304, symmetrically arranged within the punch 301. This symmetrical arrangement of the high-pressure gas channels 304 helps to evenly distribute gas pressure, ensuring the stability and consistency of the demolding process. When high-pressure gas enters the high-pressure gas channel 304 through the high-pressure gas delivery conduit 403, the gas is ejected from the channel, forming an airflow. This airflow effectively separates the workpiece from the mold.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
