[0002] The main components of a car body include the hood, body panel, trunk lid, bumper bracket, fenders, front and rear doors, roof, roof beam, side panels, windows, doors, driver's cabin, passenger cabin, engine compartment, and luggage compartment. These components together constitute the car body, providing passenger space and protection. Most car bodies are made of steel plates, alloys, and other materials, which are formed by stamping using molds. A search revealed an existing technology (publication number: CN202420420373.3) for a car body stamping mold. The document states that "this utility model, by setting up an assemblable upper mold and a lower mold, both of which are modularly designed, allows for modular replacement of the mold according to the worn parts, avoiding the need to replace the entire mold when wear occurs, thereby reducing mold replacement costs, ensuring the stamping effect of the car body, and guaranteeing the factory's economic benefits." However, the modular forming mold in the existing technology only serves a replacement function and is insufficient to effectively alleviate the problems of heat generation and friction in the forming molds of car body components. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a molding die for automotive body parts is provided to solve the problem that modular molding dies in existing technologies only serve a replacement function and are difficult to effectively reduce the heat generation and friction of automotive body part molding dies.

[0004] To achieve the above objectives, a molding die for an automobile body component is provided, comprising: a lower die, wherein an upper die is correspondingly distributed at the upper end of the lower die.

[0005] A fixed base is welded to the lower surface of the lower mold. A spray carriage is connected to the left side of the fixed base via a limiting slider. A mist nozzle is installed at equal intervals on the lower end face of the spray carriage. A protective agent storage tank is fixed to the upper surface of the spray carriage. The left side of the protective agent storage tank is connected to the mist nozzle via an infusion pipe. An air inlet is opened on the front end face of the lower mold. A cooling fan is connected to the front end of the air inlet via an air supply pipe. A first heat-conducting plate and a second heat-conducting plate are embedded and fixed inside the lower mold. A hollow cavity is opened on the inner side of the first heat-conducting plate and the second heat-conducting plate. An air outlet is provided at the rear end of the hollow cavity.

[0006] Furthermore, a positioning post is welded to the lower end face of the upper mold, a stamping mechanism is connected to the upper end face of the upper mold, and a secondary roller is installed on the lower right side surface of the spray carriage.

[0007] Furthermore, a main roller is installed on the lower left side surface of the spray carriage, a liquid guiding channel is provided inside the spray carriage, and a handle is welded to the left side of the spray carriage.

[0008] Furthermore, the infusion tube is connected to the mist nozzle through a liquid guiding channel, and an infusion pump is installed on the surface of the infusion tube.

[0009] Furthermore, a component stamping cavity is provided on the inner side of the lower mold; and a first heat-conducting plate and a second heat-conducting plate are distributed at the lower end of the component stamping cavity, and a fixing hole is provided on the surface of the fixed base.

[0010] Furthermore, a support column is welded between the upper and lower walls of the hollow cavity, and the front end of the hollow cavity is connected to the air supply pipe through an air inlet slot.

[0011] Furthermore, the second heat-conducting plate has first heat-conducting plates distributed on the left and right sides of its lower oblique end; and both the first heat-conducting plate and the second heat-conducting plate are flat rectangular in shape.

[0012] The beneficial effects of this utility model are as follows: The automotive body part molding die of this utility model utilizes a spray carriage, a mist nozzle, a protective agent storage tank, and an infusion pipe to form a spraying mechanism. The moving spray carriage drives the mist nozzle to spray the mold protective agent onto the stamping cavity surface, forming a thin film on the cavity surface of the automotive body part molding die. This helps to prevent the adhesion of automotive body part materials, reduces friction generated during stamping, and effectively reduces wear on the molding die. A cooling fan blows air into the hollow cavities of the first and second heat-conducting plates inside the mold, allowing the cold air flowing through the hollow cavities to carry away the heat generated during the stamping process, effectively controlling the temperature of the automotive body part molding die, avoiding excessively high or low temperatures that could exacerbate damage to the molding die, and improving the service life of the automotive body part molding die.

Detailed Implementation

[0019] Reference Figures 1 to 5 As shown, this utility model provides a molding die for automotive body parts, including: a lower die 1 and an upper die 2, with the upper die 2 correspondingly distributed on the upper end of the lower die 1.

[0020] A fixed base 12 is welded to the lower surface of the lower mold 1. A spray carriage 3 is connected to the left side of the fixed base 12 via a limiting slider 38. A mist nozzle 32 is installed at equal intervals on the lower end face of the spray carriage 3. A protective agent storage tank 33 is fixed to the upper surface of the spray carriage 3. The left side of the protective agent storage tank 33 is connected to the mist nozzle 32 via an infusion pipe 35. An air inlet 11 is opened on the front end face of the lower mold 1. A cooling fan 4 is connected to the front end of the air inlet 11 via an air supply pipe 41. A first heat-conducting plate 5 and a second heat-conducting plate 51 are embedded and fixed inside the lower mold 1. A hollow cavity 53 is opened on the inner side of the first heat-conducting plate 5 and the second heat-conducting plate 51. An air outlet 52 is provided at the rear end of the hollow cavity 53.

[0021] When stamping automotive body parts, the spray carriage 3 is first moved forward, and the infusion pump 36 controls the mold protectant in the protectant storage tank 33 to be sprayed onto the part stamping cavity 13 through the mist nozzle 32. After drying, the spray carriage 3 is reset. The sprayed mold protectant forms a thin film on the cavity surface of the automotive body part forming mold, which helps to prevent the adhesion of automotive body part materials, reduces friction generated during stamping, and effectively reduces wear on the forming mold. The rear door part material is placed in the lower mold 1 cavity, and the upper mold is driven by controlling the stamping mechanism 21. The die 2 is pressed downwards to shape the material of the rear door component of the car. During the pressing and shaping process, the cooling fan 4 is activated, and the cold air from the cooling fan 4 is delivered through the air inlet 11 to the hollow cavity 53 in the first heat-conducting plate 5 and the second heat-conducting plate 51. The cold air enters from the front end of the hollow cavity 53 and exits from the rear air outlet 52. The cold air flowing through the hollow cavity 53 carries away the heat generated during the stamping process of the forming mold, effectively controlling the temperature of the forming mold of the car body component, avoiding excessively high or low temperatures that may aggravate the damage to the forming mold, and improving the service life of the forming mold of the car body component.

[0022] In this embodiment, a positioning post 22 is welded to the lower end face of the upper mold 2, a stamping mechanism 21 is connected to the upper end face of the upper mold 2, and a secondary roller 31 is installed on the lower right side surface of the spray carriage 3.

[0023] In a preferred embodiment, the positioning pin 22 on the lower end face of the upper mold 2 can be easily inserted into the corresponding slot on the surface of the lower mold 1 to ensure accurate stamping position. The stamping mechanism 21 can easily drive the upper mold 2 to move upward for separation or downward for stamping. The auxiliary roller 31 rolls on the surface of the lower mold 1, serving to assist in supporting the spray carriage 3.

[0024] In this embodiment, a main roller 37 is installed on the lower left side surface of the spray carriage 3, a liquid guiding channel 39 is provided inside the spray carriage 3, and a handle 34 is welded to the left side of the spray carriage 3. The infusion pipe 35 is connected to the mist nozzle 32 through the liquid guiding channel 39, and an infusion pump 36 is installed on the surface of the infusion pipe 35.

[0025] In a preferred embodiment, the handle 34 is used to pull the spray carriage 3 to move it, so that the mist nozzle 32 of the spray carriage 3 moves along the upper end of the component stamping cavity 13 of the lower mold 1, so that the mold protectant is sprayed on the surface of the component stamping cavity 13, so that a thin film is formed on the surface of the component stamping cavity 13 of the lower mold 1, which helps to prevent the adhesion of automotive body component materials, reduce the friction generated during stamping, and effectively reduce the wear of the forming mold.

[0026] In this embodiment, a component stamping cavity 13 is provided on the inner side of the lower mold 1; and a first heat-conducting plate 5 and a second heat-conducting plate 51 are distributed at the lower end of the component stamping cavity 13, and a fixing hole 14 is provided on the surface of the fixed base 12.

[0027] In a preferred embodiment, the shape of the component stamping cavity 13 is consistent with the shape of existing automobile body components. The first heat-conducting plate 5 and the second heat-conducting plate 51 facilitate the conduction of heat generated during the stamping of the component stamping cavity 13.

[0028] In this embodiment, a support column 54 is welded between the upper and lower walls of the hollow cavity 53, and the front end of the hollow cavity 53 is connected to the air supply pipe 41 through the air inlet slot 11. The first heat-conducting plate 5 is distributed on the left and right sides of the lower end of the second heat-conducting plate 51; and both the first heat-conducting plate 5 and the second heat-conducting plate 51 are flat rectangular in shape.

[0029] In a preferred embodiment, the support column 54 facilitates the support of the hollow cavity 53 of the first heat-conducting plate 5 and the second heat-conducting plate 51, preventing the hollow cavity 53 from sinking. Cold air enters the hollow cavity 53 from the air inlet 11 on the front side of the lower mold 1, passes through the hollow cavity 53 within the first and second heat-conducting plates 5 and 51, and finally exits from the rear side of the hollow cavity 53, forming a forward-outward cooling airflow. The cold air flowing through the hollow cavity 53 exchanges heat with the heat conducted by the first and second heat-conducting plates 5 and 51 before exiting at the air outlet 52, thereby achieving a cooling effect on the stamped automotive body part forming mold. This facilitates effective temperature control of the automotive body part forming mold, preventing excessively high or low temperatures from exacerbating mold damage and improving the service life of the automotive body part forming mold.

[0030] This utility model of automotive body component forming mold can effectively solve the problem that existing modular forming molds only serve a replacement function and are difficult to effectively reduce the heat generation and friction of automotive body component forming molds. It can prevent the adhesion of automotive body component materials, reduce the friction generated during stamping, and effectively reduce the wear of forming molds. It can also effectively control the temperature of automotive body component forming molds, avoid excessively high or low temperatures from aggravating the damage of forming molds, and improve the service life of automotive body component forming molds. It is applicable to automotive body component forming molds.
