Description

Technical Field

[0001] This utility model relates to the field of automotive mold technology, and in particular to a rapid material removal structure for automotive molds. Background Technology

[0002] Automotive molds are a general term for molds used to stamp all the stamped parts of a car body, also known as "automotive body stamping molds". Examples include roof flanging molds and crossbeam reinforcement plate forming molds. The most important component of automotive molds is the body panel mold. These molds are mainly cold stamping molds, such as stamping molds, injection molds, forging molds, casting wax molds, and glass molds.

[0003] In practical applications, traditional automotive mold stripping structures generally rely on manual operation for stripping. This manual stripping mode is not only inefficient and labor-intensive, reducing the overall output speed of the production line, but also poses safety hazards because it requires workers to directly intervene in the mold area for stripping operations. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the existing automotive mold stripping structure, the stripping method is often manually operated, which is not only inefficient but also poses safety hazards. Therefore, we propose a rapid stripping structure for automotive molds.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rapid stripping structure for an automotive mold, comprising a lower mold base, a housing installed inside the lower mold base, a concave mold fixed to the top of the lower mold base, an automotive mold body movably connected above the concave mold, bases fixed at the four corners inside the housing, a support column fixed to the top of the base, the top of the support column fixed to the housing, a first movable plate slidably connected to the surface of the support column, a first support rod rotatably connected to one side of the base via a pivot, a second movable plate rotatably connected to the other end of the first support rod via a pivot, a second support rod rotatably connected to one side of the first movable plate via a pivot, the other end of the second support rod rotatably connected to the second movable plate, top rods fixed to both sides of the top of the second movable plate, the top rods penetrating the housing, the lower mold base, and the concave mold and abutting against a pressure plate, the top of the pressure plate abutting against the automotive mold body, a first spring slidably connected to the surface of the support column, one end of the first spring fixed to the first movable plate, and the other end of the first spring fixed to the base.

[0006] Preferably, the pressure plate is fixed with sliders on all four sides, and the cavity is provided with grooves on all four sides to cooperate with the sliders.

[0007] Preferably, a limiting post is fixed inside the housing, and the interior of the second movable plate is slidably connected to the surface of the limiting post.

[0008] Preferably, a fixing plate is fixed to one side of the box body, a fixing rod is slidably connected inside the fixing plate, and a fixing hole is opened inside the lower mold base to cooperate with the fixing rod.

[0009] Preferably, a disc is fixed to the surface of the fixing rod, and a second spring is slidably connected to the surface of the fixing rod. One end of the second spring is fixed to the disc, and the other end of the second spring is fixed to the fixing plate.

[0010] Preferably, the fixed plate has a rotatable limit rod inside, the bottom of the limit rod is fixed with a limit block, and one end of the limit block abuts against the disc.

[0011] Preferably, the surface of the limiting rod is fixed with limiting rings, and there are two limiting rings, which are located on both sides of the fixing plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting a push rod, a second support rod, a second movable plate, a first support rod, a first movable plate, a pillar, a base, and a first spring below the die, after the main body of the car mold is stamped, the rebound force of the first spring pushes the first movable plate to pull the second movable plate upward, thereby causing the push rod to push the pressure plate to eject the main body of the car mold from the die, thus realizing automatic unloading of the main body of the car mold. At the same time, during the pressing process, the force of the first spring can also alleviate the impact force generated by the pressing, eliminating the need for manual demolding operations and reducing the labor intensity of operators.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a rapid stripping structure for an automotive mold, including a lower mold base 1, a housing 2 installed inside the lower mold base 1, a concave mold 3 fixed to the top of the lower mold base 1, an automotive mold body 4 movably connected above the concave mold 3, bases 5 fixed at the four corners inside the housing 2, a support column 6 fixed to the top of the base 5, the top of the support column 6 fixed to the housing 2, a first movable plate 7 slidably connected to the surface of the support column 6, a first support rod 8 rotatably connected to one side of the base 5 via a pivot, a second movable plate 9 rotatably connected to the other end of the first support rod 8 via a pivot, a second support rod 10 rotatably connected to one side of the first movable plate 7 via a pivot, the other end of the second support rod 10 rotatably connected to the second movable plate 9, and push rods 11 fixed to both sides of the top of the second movable plate 9, the push rods 11 penetrating the housing 2, the lower mold base 1, and the concave mold 3 and abutting against a pressure plate 1. 3. The top of the pressure plate 13 abuts against the main body of the car mold 4. The surface of the support column 6 is slidably connected to the first spring 12. One end of the first spring 12 is fixed to the first movable plate 7, and the other end of the first spring 12 is fixed to the base 5. By setting the structure of the ejector rod 11, the second support rod 10, the second movable plate 9, the first support rod 8, the first movable plate 7, the support column 6, the base 5 and the first spring 12 below the die 3, when the main body of the car mold 4 is stamped, the rebound force of the first spring 12 pushes the first movable plate 7 to pull the second movable plate 9 upward, so that the ejector rod 11 pushes the pressure plate 13 to eject the main body of the car mold 4 from the die 3, thereby realizing the automatic unloading of the main body of the car mold 4. At the same time, during the pressing process, the force of the first spring 12 can also relieve the impact force generated by the pressing, eliminating the need for manual demolding operation and reducing the labor intensity of the operators.

[0022] Reference Figure 5As shown in this embodiment: sliders 14 are fixed around the pressure plate 13, and grooves 15 that cooperate with sliders 14 are opened around the inside of the die 3. Through the structure of sliders 14 and grooves 15, the movement trajectory of pressure plate 13 during ejection can be restricted, thereby improving its stability and enabling the main body of the automobile mold 4 to complete the demolding operation more stably.

[0023] Reference Figure 2 As shown in this embodiment: a limiting post 16 is fixed inside the housing 2, and the inside of the second movable plate 9 is slidably connected to the surface of the limiting post 16. By setting the limiting post 16, the movement trajectory of the second movable plate 9 can be restricted, thereby further improving its stability.

[0024] Reference Figure 4 As shown in this embodiment: a fixing plate 17 is fixed on one side of the box 2, and a fixing rod 18 is slidably connected inside the fixing plate 17. A fixing hole 19 is opened inside the lower mold base 1 to cooperate with the fixing rod 18. By pulling the fixing rod 18 upward until it is disengaged from the inside of the fixing hole 19, the fixing of the box 2 can be released, making it easy for the operator to take the box 2 out of the lower mold base 1, thereby facilitating the maintenance or replacement of the automatic demolding component inside the box 2.

[0025] Reference Figure 4 As shown in this embodiment: a disc 20 is fixed to the surface of the fixing rod 18, and a second spring 21 is slidably connected to the surface of the fixing rod 18. One end of the second spring 21 is fixed to the disc 20, and the other end of the second spring 21 is fixed to the fixing plate 17. A limit rod 22 is rotatably connected inside the fixing plate 17, and a limit block 23 is fixed to the bottom of the limit rod 22. One end of the limit block 23 abuts against the disc 20. Two limit rings 24 are fixed to the surface of the limit rod 22 and are located on both sides of the fixing plate 17. When the fixing plate 17 is pulled and needs to return to its original position, the fixing plate 17 is released, causing the second spring 21 to push the disc 20 due to the recovery of its elasticity. At this time, the disc 20 will drive the fixing plate 17 to insert into the fixing hole 19. Inside, it serves to reset the fixing plate 17 for easy use next time. Then, through the structure of the limiting rod 22, the limiting block 23 and the limiting ring 24, when the fixing plate 17 is away from the inside of the fixing hole 19, the box 2 can be taken out from the lower mold base 1. Then, the limiting rod 22 is rotated, which drives the limiting block 23 to block the front of the disc 20. Then the fixing plate 17 is released, so that the second spring 21 drives the disc 20 to contact the limiting block 23. At this time, the limiting block 23 will limit the disc 20. When the fixing plate 17 needs to be inserted into the inside of the fixing hole 19, the limiting rod 22 is rotated so that the limiting block 23 no longer blocks the disc 20. Then the second spring 21 will cause the disc 20 to drive the fixing plate 17 to be inserted into the inside of the fixing hole 19, thereby re-fixing the box 2.

[0026] Working principle: By setting up a structure below the die cavity 3, including an ejector rod 11, a second support rod 10, a second movable plate 9, a first support rod 8, a first movable plate 7, a support column 6, a base 5, and a first spring 12, after the car mold body 4 is stamped, the rebound force of the first spring 12 pushes the first movable plate 7 to pull the second movable plate 9 upward, thereby causing the ejector rod 11 to push the pressure plate 13 to eject the car mold body 4 from the die cavity 3, thus achieving automatic unloading of the car mold body 4. Simultaneously, during the stamping process, the force of the first spring 12... It can also alleviate the impact force generated by the mold, eliminating the need for manual demolding and reducing the labor intensity of operators. The structure of the slider 14 and the slide 15 can limit the movement trajectory of the pressure plate 13 during ejection, improving its stability and allowing the main body 4 of the automobile mold to complete the demolding operation more stably. The setting of the limiting post 16 can limit the movement trajectory of the second movable plate 9, further improving its stability. By pulling the fixing rod 18 upward until it is disengaged from the inside of the fixing hole 19, the fixing of the box 2 can be released, making it easier for the operator to remove the box 2. Removed from the lower mold base 1, facilitating maintenance or replacement of the automatic demolding assembly inside the housing 2. When the fixing plate 17 is pulled and needs to return to its original position, release the fixing plate 17. This causes the second spring 21 to push the disc 20 due to the recovery of its elasticity. At this time, the disc 20 will drive the fixing plate 17 to insert into the fixing hole 19, thus resetting the fixing plate 17 for convenient use next time. Subsequently, through the structure of the limiting rod 22, the limiting block 23, and the limiting ring 24, when the fixing plate 17 moves away from the inside of the fixing hole 19... The box 2 can be removed from the lower mold base 1. Then, the limiting rod 22 is rotated to drive the limiting block 23 to block the front of the disc 20. Then, the fixing plate 17 is released so that the second spring 21 drives the disc 20 to contact the limiting block 23. At this time, the limiting block 23 will limit the disc 20. When the fixing plate 17 needs to be inserted into the fixing hole 19, the limiting rod 22 is rotated so that the limiting block 23 no longer blocks the disc 20. Then, the second spring 21 will cause the disc 20 to drive the fixing plate 17 to be inserted into the fixing hole 19, thereby re-fixing the box 2.
