Abstract
Description
Technical Field
[0001] This utility model relates to the field of leather bowl shaping technology, specifically to a leather bowl shaping device. Background Technology
[0002] As one of the core components of the automotive brake booster system, the processing method of the diaphragm seal is quite special. A flat gasket is machined out and then processed into a certain shape to meet customer requirements. If the final shape is directly machined, too much material cost will be wasted. Therefore, the sheet material is machined first and then processed into a secondary shape using forming tooling technology. The existing forming tooling uses upper and lower molds to press and deform the material to obtain the final product.
[0003] In the prior art, in order to facilitate demolding after product shaping, a mold core that can move elastically is usually configured in the lower mold. Utilizing the elastic characteristics of the mold core, when the upper mold presses down on the product pad, the mold core can be appropriately compressed and elastically store energy. Thus, when the upper mold returns to its original position and moves upward, the mold core can quickly push the product upward under elastic force, assisting in the demolding of the product.
[0004] However, the existing mold core's elastic movement mainly relies on springs. As a vulnerable component, springs are prone to severe fatigue after repeated use, which reduces their elasticity to the mold core. Moreover, springs are mostly installed between the mold core and the bottom of the lower mold cavity, which is a relatively enclosed space, making it very inconvenient to replace the springs and reducing the effectiveness to some extent. Utility Model Content
[0005] To solve the above-mentioned technical problems, a leather cup shaping device is provided, which solves the problem that in the prior art, the elastic movement of the mold core mainly relies on springs. As a vulnerable part, the spring is prone to severe fatigue after repeated use, which reduces its elasticity to the mold core. However, the springs are mostly installed between the mold core and the bottom of the lower mold cavity, and the space is relatively closed, which makes it very inconvenient to replace the springs and reduces the performance to a certain extent.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a leather cup shaping device, including a lower mold, a mold cavity opened on the lower mold, and a mold core that can be elastically moved in the mold cavity, and also including a movable circular groove disposed in the inner wall of the lower mold, one side of the movable circular groove being connected to the outside, and the other side of the movable circular groove being connected to the inner cavity of the mold cavity, and the movable circular groove having a built-in multi-station rebound mechanism;
[0007] The multi-station rebound mechanism includes a rotating carrier plate arranged laterally in the inner cavity of the movable circular groove, elastic members detachably arranged at both ends of the rotating carrier plate, and a rotation supply part arranged in the middle section of the rotating carrier plate, wherein one of the elastic members is located directly below the mold core.
[0008] Preferably, the elastic element includes a connecting frame detachable from the end of the rotating carrier plate by bolts and a compression spring fixed to the top surface of the connecting frame.
[0009] Preferably, the rotating part includes a drive column vertically disposed in the inner cavity of the movable circular groove and a connecting ring fastened to the drive column rod, and the rotating carrier plate is fastened to the connecting ring.
[0010] Preferably, a driving cavity is provided on the inner wall of the top of the movable circular groove, and a movable column is vertically rotatably connected to the inner wall of the top of the driving cavity. The end of the movable column is fixedly connected to the top of the driving column. A control column is provided on the outer side of the lower mold. One end of the control column is rotatably inserted into the driving cavity and is connected to the movable column through a bevel gear.
[0011] Preferably, two support seats are symmetrically fixed on both sides of the bottom of the mold core, one of which has a notch adapted to the rotating carrier plate.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] By setting up a multi-station rebound mechanism, one set of elastic elements at both ends of the rotating carrier plate is located below the mold core to provide elastic potential energy to the mold core, while the other set is kept as a backup. Thus, when the compression spring below the mold core is fatigued due to repeated compression, it is only necessary to switch the two ends of the rotating carrier plate by using the supply and rotation part to quickly switch to a good elastic element below the mold core, so that the mold core can continue to move elastically for a short period of time.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0020] Reference Figure 1 , Figure 2 and Figure 3 As shown, a leather cup shaping device includes a lower mold 1, a mold cavity 3 opened on the lower mold 1, and a mold core 2 that can be elastically moved within the mold cavity 3;
[0021] In use, the product pad to be processed is placed on the lower mold 1 beforehand, and then the upper mold is pressed on the lower mold 1. When the upper mold and the lower mold 1 close and press the pad together to shape it, the mold core 2 is pressed to the inside of the lower mold 1 and contracts to a certain extent and stores elastic potential energy. Thus, after the upper mold is reset, the mold core 2 will push the product upward under its own elastic force to assist in the demolding of the product.
[0022] Furthermore, referring to Figure 2 and Figure 3 As shown, it is worth noting that it also includes a movable circular groove 4 set in the inner wall of the lower mold 1. One side of the movable circular groove 4 is connected to the outside, and the other side of the movable circular groove 4 is connected to the inner cavity of the mold cavity 3. The movable circular groove 4 has a built-in multi-station rebound mechanism.
[0023] The multi-station rebound mechanism includes a rotating carrier plate 5 arranged laterally in the inner cavity of the movable circular groove 4, elastic elements detachably arranged at both ends of the rotating carrier plate 5, and a feed part arranged in the middle section of the rotating carrier plate 5, wherein one of the elastic elements is located directly below the mold core 2.
[0024] The elastic element includes a connecting frame 6 that is detachable from the end of the rotating carrier plate 5 by bolts and a compression spring 7 fixed to the top surface of the connecting frame 6;
[0025] By setting up a multi-station rebound mechanism, one set of elastic elements at both ends of the rotating carrier plate 5 is located below the mold core 2 to provide elastic potential energy to the mold core 2, while the other set is reserved for backup.
[0026] Therefore, when the upper mold approaches the lower mold 1 to press and shape the gasket, the mold core 2 is forced to shrink the inner cavity of the mold cavity 3 and compress the compression spring 7 in the elastic component below it, so that the compression spring 7 is deformed and stores elastic potential energy. After the upper mold is reset, the mold core 2 will push the product upward under the elastic force of the compression spring 7 to assist the demolding of the product.
[0027] When the compression spring 7 under the mold core 2 is fatigued by repeated compression, it is only necessary to use the supply and rotation part to change the two ends of the rotating carrier plate 5, so that a good elastic element can be quickly switched under the mold core 2, making it convenient for the mold core 2 to continue elastic movement in a short time.
[0028] Furthermore, after replacing the damaged elastic element of the compression spring 7, the elastic element is located at the opening position where the movable circular groove 4 connects to the outside. Then, by loosening the bolts connecting the connecting frame 6 and the rotating carrier plate 5, the connecting frame 6 can be quickly disassembled and the damaged compression spring 7 can be replaced.
[0029] Furthermore, referring to Figure 3 As shown, it is worth noting that the rotating part includes a drive column 8 vertically arranged in the inner cavity of the movable circular groove 4 and a connecting ring fastened to the rod of the drive column 8, and the rotating carrier plate 5 is fastened to the connecting ring.
[0030] By controlling the rotation of the drive column 8, the drive column 8 can drive the rotating carrier plate 5 to rotate synchronously through the connecting ring, thereby changing the positions of the two ends of the rotating carrier plate 5.
[0031] Furthermore, referring to Figure 3 As shown, it is worth noting that a drive cavity is provided on the inner wall of the top of the movable circular groove 4, and a movable column 9 is vertically rotatably connected to the inner wall of the top of the drive cavity. The end of the movable column 9 is fixedly connected to the top of the drive column 8. A control column 10 is provided on the outer side of the lower mold 1. One end of the control column 10 rotates into the drive cavity and is connected to the movable column 9 through a bevel gear.
[0032] The knob control column 10, through which the bevel gear drives the movable column 9, provides rotational power to the drive column 8 and the rotating carrier plate 5 as a whole.
[0033] Furthermore, referring to Figure 3 As shown, it is worth noting that two support seats 11 are symmetrically fixed on both sides of the bottom of the mold core 2, and one of the support seats 11 has a notch that is compatible with the rotating carrier plate 5.
[0034] By setting the support seat 11, after the mold core 2 contracts into the mold cavity 3 under force, a certain gap can be left between it and the inner wall of the bottom end of the mold cavity 3, so as to prevent the mold core 2 from over-compressing the compression spring 7 and causing the compression spring 7 to break.
[0035] Furthermore, by setting the notch, the rotating carrier plate 5 can be precisely inserted into the notch after the support base 11 moves down along with the mold core 2, so as not to hinder the overall downward movement of the mold core 2 and the support base 11.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
