Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an integrated stamping die. Background Technology

[0002] Automotive stamping parts are a widely used type of metal processing products. They are made by punching the required holes and profiles into the material. The shape, size and position of the holes and profiles must be consistent with the drawings, and the deviation must be within the dimensional tolerances specified by the manufacturing industry. The surface must be good and free of obvious defects such as burrs, bevels and scratches.

[0003] A search of existing Chinese patent technology reveals a "stamping die" with publication number "CN218310347U". This device forms a dual guide and constraint, making the guidance more precise and preventing the slider on the wedge from deviating during sliding. However, during continuous operation, this device causes the stamping die to generate heat. When the metal is affected by heat, it will affect the accuracy of the stamped product and the stamping effect. Utility Model Content

[0004] Based on this, it is necessary to address the issue that during continuous operation, the stamping die generates heat, which affects the precision of the stamped product and the stamping effect. The solution is an integrated stamping die comprising: two mounting bases, with multiple guide telescopic rods fixedly connected to opposite sides of the two mounting bases in an array. Springs are fitted onto the surfaces of the guide telescopic rods, with the upper and lower ends of the springs abutting against the surfaces of adjacent mounting bases; a heat dissipation mechanism installed between the two mounting bases, connected to the surfaces of adjacent mounting bases, and extending through the adjacent mounting bases to the outside; wherein the heat dissipation mechanism includes a die base fixedly connected to the surfaces of the adjacent mounting bases, with a side vent at one end of the die base. An air-cooling component is installed inside the side vent, and a water-cooling component is installed on the side of the die base away from the air-cooling component, extending into the interior of the die base.

[0005] In one embodiment, the water-cooling assembly includes two main pipes embedded inside the mold base. The two main pipes are located on both sides of the side vent. The lower ends of the two main pipes are fixedly connected to multiple diversion copper pipes. Multiple welded copper strips are fixedly connected to the surface of the diversion copper pipes. A connector is provided at the end of the main pipe away from the air-cooling assembly. The connector is installed at the other end of the mold base.

[0006] In one embodiment, the air-cooling assembly includes an external chamber fixedly connected to one end of the mold base. A positioning plate is fixedly connected to the inner wall of the external chamber. A filter screen is fixedly connected to one side of the external chamber. Multiple motor fans are arranged inside the external chamber. The motor fans are installed on one side of the positioning plate. Heat-conducting strips are fixedly connected to the inner top wall and inner bottom wall of the external chamber, respectively. The upper heat-conducting strips and the lower heat-conducting strips are staggered.

[0007] In one embodiment, a plurality of the diversion copper pipes are evenly distributed in a straight line along the axis of the main pipe, the upper end of the diversion copper pipe is connected to the surface of the adjacent main pipe, and the longitudinal cross section of the diversion copper pipe is U-shaped.

[0008] In one embodiment, a plurality of the welding copper strips are evenly distributed in a ring along the surface of the diversion copper pipe, the welding copper strips are located below the side vent holes, and the welding copper strips are embedded in the interior of the mold base.

[0009] In one embodiment, a connecting pipe is fixedly connected to the surface of the connector, and the other end of the connecting pipe passes through an adjacent mounting base. One end of the connecting pipe furthest from the connector can be externally connected to a pump body; this can be adjusted appropriately according to the application.

[0010] In one embodiment, the surface of the heat-conducting strip extends into the interior of the side vent, the inner wall of the side vent is fixedly connected to the surface of the heat-conducting strip, and a metal shell is fixedly connected to the surface of the heat-conducting strip away from the side vent.

[0011] In one embodiment, the upper and lower ends of the external compartment are fixedly connected with connecting brackets, which are fixedly connected to the surface of the mold base.

[0012] Beneficial effects

[0013] The aforementioned integrated stamping die, through the water-cooling components, allows the external liquid to continuously absorb the heat generated during the operation of the die holder. The air cylinder, through the combination of the diversion copper pipe and the welded copper strip, increases the contact area for heat exchange. During the stamping process, the liquid flow carries away the generated heat, thereby reducing the impact of heat on the stamping die during the stamping process and maintaining a good stamping effect.

[0014] By setting up an air-cooling component, the airflow from the motor fan inside the external chamber is guided to the side vent. When the airflow passes through the side vent, it comes into contact with the heat-conducting strip and the surface of the metal shell and carries away the heat. The metal shell and heat-conducting strip increase the contact area for heat exchange, reduce the impact of heat on the stamping die, and maintain good stamping performance.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The following is combined Figures 1-5 This invention describes an integrated stamping die.

[0025] In one embodiment, an integrated stamping die includes: two mounting bases 1, with multiple guide telescopic rods 2 fixedly connected to opposite sides of the two mounting bases 1, the multiple guide telescopic rods 2 being arranged in an array, and springs sleeved on the surface of the guide telescopic rods 2, the upper and lower ends of the springs abutting against the surface of the adjacent mounting base 1; and a heat dissipation mechanism 3, which is installed between the two mounting bases 1, connected to the surface of the adjacent mounting base 1, and the surface of the heat dissipation mechanism 3 penetrating the adjacent mounting base 1 and extending to the outside.

[0026] The heat dissipation mechanism 3 includes a mold base 31 fixedly connected to the surface of an adjacent mounting base 1. One end of the mold base 31 is provided with a side vent 311. An air-cooling component 33 is installed inside the side vent 311. A water-cooling component 32 is installed on the side of the mold base 31 away from the air-cooling component 33. The water-cooling component 32 extends into the interior of the mold base 31.

[0027] It should be noted that the stamping mold for the car trunk lid is as follows: The mold for large cover parts adopts a frame structure to enhance stability in order to match the large size characteristics of the trunk lid. For mold material selection, working parts such as the punch and die should preferably use tool steel Cr12MoV, DC53, etc.; non-critical structural parts can use high-strength cast iron to reduce costs; symmetrical parts can adopt a mold closing design to reduce processes.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the water-cooling assembly 32 includes two main pipes 321 embedded in the mold base 31. The two main pipes 321 are located on both sides of the side vent 311. The lower ends of the two main pipes 321 are fixedly connected to multiple branch copper pipes 323. Multiple welded copper strips 325 are fixedly connected to the surface of the branch copper pipes 323. A connector 322 is provided at the end of the main pipe 321 away from the air-cooling assembly 33. The connector 322 is installed at the other end of the mold base 31.

[0029] Multiple diversion copper pipes 323 are evenly distributed in a straight line along the axis of the main pipe 321. The upper end of the diversion copper pipe 323 is connected to the surface of the adjacent main pipe 321. The longitudinal section of the diversion copper pipe 323 is U-shaped. Multiple welded copper strips 325 are evenly distributed in a ring shape along the surface of the diversion copper pipe 323. The welded copper strips 325 are located below the side vent 311. The welded copper strips 325 are embedded in the mold base 31. A connecting pipe 324 is fixedly connected to the surface of the connector 322. The other end of the connecting pipe 324 passes through the adjacent mounting base 1.

[0030] In this embodiment, the device guides liquid through a connecting pipe 324 and a connector 322 to the interior of an adjacent main pipe 321. The liquid is then evenly guided through the main pipe 321 to the interior of multiple branch copper pipes 323. The liquid is guided through the branch copper pipes 323. Since the branch copper pipes 323 are U-shaped longitudinally, and multiple welded copper strips 325 are connected to the surface of the stamping surface of the mold base 31 near the surface of the branch copper pipes 323, the liquid exchanges heat with the welded copper strips 325 through the branch copper pipes 323 and the heat generated during the stamping process. The liquid carries away the heat during the flow of the liquid, so that the stamping of the mold base 31 maintains a good stamping effect.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the air-cooled assembly 33 includes an external chamber 331 fixedly connected to one end of the mold base 31. A positioning plate 332 is fixedly connected to the inner wall of the external chamber 331. A filter screen 334 is fixedly connected to one side of the external chamber 331. Multiple motor fans 333 are installed inside the external chamber 331. The motor fans 333 are installed on one side of the positioning plate 332. Heat-conducting strips 336 are fixedly connected to the inner top wall and inner bottom wall of the external chamber 331 respectively. The upper heat-conducting strips 336 and the lower heat-conducting strips 336 are staggered.

[0032] The surface of the heat-conducting strip 336 extends into the interior of the side vent 311. The inner wall of the side vent 311 is fixedly connected to the surface of the heat-conducting strip 336. A metal shell 335 is fixedly connected to the surface of the heat-conducting strip 336 away from the side vent 311. Connecting brackets 337 are fixedly connected to the upper and lower ends of the external compartment 331. The connecting brackets 337 are fixedly connected to the surface of the mold base 31.

[0033] In this embodiment, the airflow from the motor fan 333 inside the external chamber 331 is guided to the interior of the side vent 311. The airflow is further filtered by a filter 334, and the motor fan 333 is positioned by a positioning plate 332. At the same time, the connecting bracket 337 positions the external chamber 331 so that the external chamber 331 is connected to the side vent 311. The airflow passes through the side vent 311 and contacts the heat-conducting strip 336 and the metal shell 335 to remove heat, thereby reducing the heat loss and maintaining good heat dissipation of the mold base 31.

[0034] Working principle: Liquid is guided through connector 322 into the interior of adjacent main pipe 321. Liquid in main pipe 321 is evenly guided into the interior of multiple branch copper pipes 323. The branch copper pipes 323 guide the liquid. Since the branch copper pipes 323 are U-shaped longitudinally, multiple welded copper strips 325 are connected to the surface of the branch copper pipes 323 near the stamping surface of the mold base 31 to help absorb heat and increase the heat exchange area. Liquid exchanges heat generated during stamping through branch copper pipes 323 and welded copper strips 325. During the liquid flow, heat is carried away. The airflow of motor fan 333 inside external chamber 331 is guided to the interior of side vent 311. The airflow is filtered by filter screen 334 and positioned by positioning plate 332. At the same time, corner bracket 337 positions external chamber 331 and connects external chamber 331 to side vent 311. Airflow comes into contact with heat conduction strip 336 and metal shell 335 through side vent 311 and carries away heat, reducing the heat loss of mold base 31 and maintaining good heat dissipation effect.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
