Description

Technical Field

[0001] The utility model belongs to the technical field of automobile upper cover processing molds, and specifically relates to a mold for producing automobile upper covers. Background Art

[0002] The front cover of a car is also known as the hood of an automobile, which is an external protective device for the automobile engine. The existing mold includes an upper mold and a lower mold. When in use, the workpiece is placed on the lower mold, and then the hydraulic cylinder drives the upper mold downward to pressurize the workpiece, so that it forms a shape that matches the molding groove of the lower mold.

[0003] However, the stamping die cannot reduce the friction between the upper die and the workpiece during use, which can easily cause wear and tear on the upper die, thus affecting the processing accuracy. In addition, the stamping die has a short service life and needs to be replaced regularly, which increases production costs.

[0004] At the same time, impurities are easily adhered to the upper die during stamping. If they are not cleaned in time, these impurities are easy to cause damage to the upper die during stamping, thereby affecting the forming of the workpiece.

[0005] To this end, we proposed a mold for producing automobile upper covers, which can not only reduce the friction between the upper mold and the upper cover, thereby effectively preventing the upper mold from being damaged due to excessive pressure, but also remove impurities on the upper mold to prevent damage to the upper mold. Utility Model Content

[0006] The purpose of the utility model is to provide a mold for producing automobile upper covers, which can not only reduce the friction between the upper mold and the upper cover, thereby effectively preventing the upper mold from being damaged due to excessive pressure, but also can remove impurities on the upper mold to prevent damage to the upper mold.

[0007] The technical solutions adopted in this utility are as follows:

[0008] A mold for producing an automobile upper cover, comprising an upper mold and a lower mold, wherein a first mounting plate is mounted on the top of the upper mold, and a second mounting plate is mounted on the bottom of the lower mold;

[0009] A first rectangular groove is provided in the first mounting plate, a compression assembly is arranged inside the first rectangular groove, a rectangular hollow plate sleeved on the upper mold is installed on the compression bottom, a first magnetic surface is arranged at the bottom of the rectangular hollow plate, lubricating oil is arranged inside the hollow cavity of the rectangular hollow plate, a rectangular sponge layer is arranged on the inner wall of the rectangular hollow plate, and the rectangular sponge layer is fitted with the upper mold;

[0010] A second rectangular groove is formed on the second mounting plate, a rectangular frame is installed inside the second rectangular groove, a second magnetic surface is provided on the upper surface of the rectangular frame, and the second magnetic surface repels the first magnetic surface.

[0011] Furthermore, a plurality of through holes are provided on the inner wall of the rectangular hollow plate.

[0012] Furthermore, an oil inlet pipe is provided on the rectangular hollow plate, and a sealing cover is provided on the oil inlet pipe.

[0013] Furthermore, the height of the rectangular hollow plate is smaller than the depth of the first rectangular groove.

[0014] Furthermore, the compression assembly includes a hollow cylinder connected to the inner wall of the first rectangular groove, a spring is arranged inside the hollow cylinder, a piston disk is arranged at the bottom of the spring, a connecting rod is installed at the bottom of the piston disk, and the bottom of the connecting rod passes through the hollow cylinder and is connected to the rectangular hollow plate.

[0015] Furthermore, the length and width of the rectangular hollow plate are the same as the length and width of the rectangular frame.

[0016] The technical effects achieved by this utility model are:

[0017] 1. By moving the upper die downward, when the upper die enters the molding cavity of the lower die at this time, the first magnetic surface repels the second magnetic surface, so that the rectangular hollow plate will not move downward, and the rectangular hollow plate will move the connecting rod through the rectangular hollow plate to make the piston disc squeeze the spring inside the hollow cylinder, thereby compressing the rectangular hollow plate, and the compressed rectangular hollow plate enters the first rectangular groove. At the same time, when the upper die slowly enters the molding cavity of the lower die, the lubricating oil inside the rectangular hollow plate is absorbed through the rectangular sponge layer, and the rectangular sponge layer has lubricating liquid. Since the upper die moves downward, the rectangular hollow plate will not move, and the rectangular sponge layer is smeared on the outside of the upper die, so as to lubricate the upper die when the upper cover is pressed down, reduce the friction between the upper die and the upper cover, and effectively prevent the upper die from being damaged due to excessive pressure.

[0018] 2. After the upper cover is manufactured, the upper die moves up. At this time, the rectangular hollow plate is located on the inner wall of the first rectangular groove. When the repulsive magnetism disappears, the elastic potential energy of the spring is released, causing the rectangular hollow plate to move down, thereby lubricating the upper die again and removing impurities to prevent damage to the upper die. The device can not only reduce the friction between the upper die and the upper cover, thereby effectively preventing the upper die from being damaged due to excessive pressure, but also remove impurities on the upper die to prevent damage to the upper die.

DETAILED DESCRIPTION

[0027] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0028] like Figure 1-6 As shown, the technical solution adopted by the present invention is specifically as follows: a mold for producing an automobile upper cover, comprising an upper mold 1 and a lower mold 2, a first mounting plate 3 is installed on the top of the upper mold 1, and a second mounting plate 4 is installed on the bottom of the lower mold 2, wherein the first mounting plate 3 is detachably connected to the upper mold 1, and the connection method here is bolt connection, and the second mounting plate 4 is detachably connected to the lower mold 2, and the connection method here is bolt connection, which is convenient for the upper mold 1 and the lower mold 2 to be installed and disassembled, belongs to the prior art, and will not be described in detail here.

[0029] A first rectangular groove 5 is provided on the first mounting plate 3, a compression assembly is arranged inside the first rectangular groove 5, a rectangular hollow plate 6 sleeved on the upper mold 1 is installed at the compression bottom, a first magnetic surface 7 is arranged at the bottom of the rectangular hollow plate 6, lubricating oil is arranged inside the hollow cavity of the rectangular hollow plate 6, a rectangular sponge layer 8 is arranged on the inner wall of the rectangular hollow plate 6, and the rectangular sponge layer 8 is fitted with the upper mold 1;

[0030] The second mounting plate 4 is provided with a second rectangular groove 9 , a rectangular frame 10 is installed inside the second rectangular groove 9 , and a second magnetic surface 11 is provided on the upper surface of the rectangular frame 10 , and the second magnetic surface 11 repels the first magnetic surface 7 .

[0031] The working principle is as follows: when the upper mold 1 moves downward, when the upper mold 1 enters the molding cavity of the lower mold 2, the first magnetic surface 7 repels the second magnetic surface 11, so that the rectangular hollow plate 6 does not move downward, and the rectangular hollow plate 6 enters the first rectangular groove 5 through the compression assembly. When the upper mold 1 slowly enters the molding cavity of the lower mold 2, the lubricating oil inside the rectangular hollow plate 6 is absorbed by the rectangular sponge layer 8. The rectangular sponge layer 8 has lubricating liquid. As the upper mold 1 moves downward, the rectangular hollow plate 6 does not move, and the rectangular sponge layer 8 enters the outer side of the upper mold 1. The upper mold 1 is applied to lubricate the upper mold 1 when the upper cover is pressed down, reducing the friction between the upper mold 1 and the upper cover, thereby effectively preventing the upper mold 1 from being damaged due to excessive pressure. After the upper cover is manufactured, the upper mold 1 moves up. At this time, the rectangular hollow plate 6 is located on the inner wall of the first rectangular groove 5. When the repulsive magnetism disappears, the compression assembly drives the rectangular hollow plate 6 to return to its original position and move down, lubricating the upper mold 1 again, and at the same time, the impurities on the upper mold 1 can be cleared, thereby effectively preventing the upper mold 1 from being damaged due to friction and impurities.

[0032] In order to ensure that the lubricating oil can enter the rectangular sponge layer 8, a plurality of through holes are opened on the inner wall of the rectangular hollow plate 6, and the lubricating oil can soak the rectangular sponge layer 8 through the through holes, so that it can be used conveniently.

[0033] At the same time, an oil inlet pipe 12 is provided on the rectangular hollow plate 6, and a sealing cover is provided on the oil inlet pipe 12. The lubricating oil enters the rectangular hollow plate 6 through the oil inlet pipe 12, and the purpose of providing the sealing cover is to seal and prevent the lubricating oil from leaking.

[0034] During stamping, in order to prevent the rectangular hollow plate 6 from interfering with the stamping, the height of the rectangular hollow plate 6 is smaller than the depth of the first rectangular groove 5. The advantage of this is that when the upper mold 1 and the lower mold 2 are fully fitted together, the rectangular hollow plate 6 will enter the first rectangular groove 5 and be hidden, thereby not affecting the stamping.

[0035] like Figure 5-6 As shown, the compression assembly includes a hollow cylinder 13 connected to the inner wall of the first rectangular groove 5, a spring 14 is arranged inside the hollow cylinder 13, a piston disk 15 is arranged at the bottom of the spring 14, a connecting rod 16 is installed at the bottom of the piston disk 15, and the bottom of the connecting rod 16 passes through the hollow cylinder 13 and is connected to the rectangular hollow plate 6.

[0036] Among them, when the upper mold 1 moves downward, because the first magnetic surface 7 repels the second magnetic surface 11, the rectangular hollow plate 6 will drive the connecting rod 16 to make the piston disc 15 squeeze the spring 14 inside the hollow cylinder 13, thereby compressing it. The compressed rectangular hollow plate 6 enters the first rectangular groove 5, thereby applying lubricating oil to the outside of the upper mold 1.

[0037] At the same time, when the upper die 1 moves up, that is, after the stamping is completed, the elastic potential energy of the spring 14 is released, causing the rectangular hollow plate 6 to move down, thereby lubricating the upper die 1 again and removing impurities to prevent damage to the upper die 1.

[0038] It should be noted that, in order to ensure that the rectangular hollow plate 6 can enter the first rectangular groove 5 , the depth of the first rectangular groove 5 is greater than the height of the hollow tube 13 and the height of the rectangular hollow plate 6 .

[0039] In order to make the first magnetic surface 7 repel the second magnetic surface 11, the length and width of the rectangular hollow plate 6 are the same as the length and width of the rectangular frame 10, which means that the positions of the rectangular hollow plate 6 and the rectangular frame 10 correspond to each other, so that the first magnetic surface 7 corresponds to the second magnetic surface 11.

[0040] It should be noted that: the first mounting plate 3 and the second mounting plate 4 fix the upper mold 1 and the lower mold 2 through an external bracket, and a hydraulic assembly is provided on the upper mold 1, the hydraulic assembly includes a hydraulic cylinder and a hydraulic rod with a telescopic end of the hydraulic cylinder, and the bottom of the hydraulic rod is connected to the first mounting plate 3, so that the hydraulic cylinder can drive the hydraulic rod to make the first mounting plate 3 drive the upper mold 1 to move up and down, thereby working, which belongs to the prior art and will not be elaborated here.

[0041] After exploration, it was found that since the upper mold 1 and the upper mold 1 themselves have a lot of weight, the energy consumption will increase when working. The utility model can not only reduce the counterweight by opening the first rectangular groove 5 and the second rectangular groove 9, but also prevent the upper mold 1 from being damaged due to friction and impurities. In order to further reduce the counterweight, the rectangular hollow plate 6 and the rectangular frame 10 are made of plastic. Because the rectangular hollow plate 6 and the rectangular frame 10 are both arranged inside the first rectangular groove 5 and the second rectangular groove 9, the pressure they are subjected to is the force of magnetic repulsion, so they will not be easily damaged, which can further reduce the counterweight.

[0042] The working principle of the utility model is as follows: firstly, the cover plate material is placed on the lower die 2, and then the upper die 1 is moved downward. At this time, when the upper die 1 enters the molding cavity of the lower die 2, the first magnetic surface 7 repels the second magnetic surface 11, thereby causing the rectangular hollow plate 6 to not move downward, and the rectangular hollow plate 6 moves the connecting rod 16 through the rectangular hollow plate 6 to make the piston disc 15 squeeze the spring 14 inside the hollow cylinder 13, thereby compressing, and the compressed rectangular hollow plate 6 enters the first rectangular groove 5. At the same time, when the upper die 1 slowly enters the molding cavity of the lower die 2, the lubricating oil inside the rectangular hollow plate 6 is absorbed through the rectangular sponge layer 8, and the rectangular sponge layer 8 has lubricating liquid. Since the upper die 1 moves downward, the rectangular hollow plate 6 will not move, and the rectangular sea The cotton layer 8 is applied on the outer side of the upper mold 1, so as to lubricate the upper mold 1 when the upper cover is pressed down, reduce the friction between the upper mold 1 and the upper cover, and effectively prevent the upper mold 1 from being damaged due to excessive pressure. After the upper cover is manufactured, the upper mold 1 moves up. At this time, the rectangular hollow plate 6 is located on the inner wall of the first rectangular groove 5. When the repulsive magnetism disappears, the elastic potential energy is released by the spring 14, so that the rectangular hollow plate 6 moves down, so as to lubricate the upper mold 1 again, and also remove impurities to prevent the upper mold 1 from being damaged. The device can not only reduce the friction between the upper mold 1 and the upper cover, thereby effectively preventing the upper mold 1 from being damaged due to excessive pressure, but also remove impurities on the upper mold 1 to prevent the upper mold 1 from being damaged.

[0043] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
