Description

Technical Field

[0001] This utility model relates to a rubber stopper processing device, specifically a rubber stopper hydraulic molding device. Background Technology

[0002] The rubber stopper processing requires the use of a hydraulic forming device, which is a device that combines hydraulic transmission and mold forming technology. Its core function is to drive the mold to close and apply pressure through high-pressure oil to achieve precise forming of the rubber stopper.

[0003] Existing hydraulic molding equipment for rubber plugs is not conducive to achieving precise automatic demolding control after molding. Even if automatic demolding is possible, the movement distance of the auxiliary demolding structure cannot be precisely controlled. Therefore, manual operation is usually required, resulting in a low degree of automation. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic molding device for rubber plugs, which has the advantages of automatic demolding and precise control of the demolding process. No external instruments or manual intervention are required during the demolding process, making the automatic demolding operation more convenient and the degree of automation higher.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber stopper hydraulic molding device, comprising a lower mold and an upper mold fixed to the upper end face of the lower mold, a molding groove is provided at the center of the upper end face of the lower mold, and a hydraulic molding mechanism and an automatic demolding mechanism are provided on the lower mold. The hydraulic molding mechanism includes a hydraulic cylinder and a lifting platform fixed to the output end of the hydraulic cylinder. The hydraulic cylinder is fixed to the upper end face of the upper mold, and a molding punch is fixed to the lower end face of the lifting platform. The automatic demolding mechanism includes a guide tube and a guide post passing through the guide tube. A bottom plate is fixed to the bottom of the guide post, and a demolding auxiliary plate and an inner plate are provided above the bottom plate. The demolding auxiliary plate and the inner plate are connected by multiple connecting posts, and the multiple connecting posts slide through the lower mold.

[0006] Preferably, a positioning groove is provided on the lower end face of the lower mold, and the depth of the positioning groove is equal to the height of the demolding auxiliary plate.

[0007] Preferably, a material receiving groove is provided on the lower end face of the forming punch, and a sealing block is fixed in the material receiving groove.

[0008] Preferably, the inner plate is horizontally positioned at the bottom of the forming groove, and the inner plate is in contact with the inner wall of the forming groove.

[0009] Preferably, there are two guide tubes and two guide posts, and the two guide posts are fixed to the lower end face of the lifting platform. The two guide posts are respectively located on both sides of the upper end face of the bottom plate.

[0010] Preferably, the conduit is a cavity structure with openings at both ends and a hollow interior, and both conduits are fixed inside the lower mold, with two guide posts slidably disposed inside the two conduits respectively.

[0021] Please see Figure 1 An embodiment of this utility model is provided: a rubber stopper hydraulic molding device, including a lower mold 1 and an upper mold 2 fixed to the upper end face of the lower mold 1. A molding groove 3 is provided at the center of the upper end face of the lower mold 1, and a hydraulic molding mechanism 4 and an automatic demolding mechanism 5 are provided on the lower mold 1. Multiple support feet 6 are fixed on the lower end face of the lower mold 1.

[0022] Please see Figure 2 The hydraulic forming mechanism 4 includes a hydraulic cylinder 41 and a lifting platform 42 fixed to the output end of the hydraulic cylinder 41. The hydraulic cylinder 41 is fixed to the upper end face of the upper mold 2, and a forming punch 43 is fixed to the lower end face of the lifting platform 42.

[0023] Please see Figure 3A positioning groove 11 is provided on the lower end face of the lower mold 1, and a material receiving groove 431 is provided on the lower end face of the forming punch 43. A sealing block 44 is fixed in the material receiving groove 431. The height of the material receiving groove 431 can be determined by setting sealing blocks 44 of different heights. In actual design, the height of the material receiving groove 431 can be determined according to the specifications of the rubber plugs actually processed. The automatic demolding mechanism 5 includes two guide tubes 51 and guide pillars 52 passing through the two guide tubes 51 respectively. The guide tubes 51 are cavity structures with openings at both ends and hollow inside. Both guide tubes 51 are fixed inside the lower mold 1. The two guide pillars 52 are slidably arranged in the two guide tubes 51 respectively. Both guide pillars 52 are fixed to the lower end face of the lifting platform 42. A bottom plate 53 is fixed at the bottom of the two guide pillars 52. The bottom plate 53 is arranged between multiple support feet 6. When the two guide pillars 52 are fixed, the bottom plate 53 is fixed between multiple support feet 6. When the column 52 slides together, it can drive the bottom plate 53 to rise and fall smoothly. A demolding auxiliary plate 54 and an inner plate 56 are provided above the bottom plate 53. The depth of the positioning groove 11 is equal to the height of the demolding auxiliary plate 54, that is, the positioning groove 11 and the demolding auxiliary plate 54 can be fully adapted. When the demolding auxiliary plate 54 enters the positioning groove 11 and is fully attached to the lower mold 1, the inner plate 56 can just push the molded plug completely out of the molding groove 3. The inner plate 56 is horizontally set at the bottom of the molding groove 3 and is attached to the inner wall of the molding groove 3. The demolding auxiliary plate 54 and the inner plate 56 are connected by multiple connecting columns 55. Both the demolding auxiliary plate 54 and the inner plate 56 are horizontally set, and the demolding auxiliary plate 54 is set below the lower mold 1. The multiple connecting columns 55 slide through the lower mold 1 and are vertically set.

[0024] Please refer to the following: Figures 1 to 3 In the operation of this utility model, the corresponding material is injected into the molding groove 3, and then the hydraulic cylinder 41 is driven to move the molding punch 43 and the sealing block 44 to sink. When the lifting platform 42 is attached to the upper end face of the lower mold 1, the mold is closed. After that, the space in the molding groove 3 and the space in the material container 431 are used to shape the rubber plug. After molding, the hydraulic cylinder 41 drives the lifting platform 42 and the molding punch 43 to rise. During this process, the molding punch 43 and the sealing block 44 are disengaged from the molding groove 3. Then the bottom plate 53 contacts the demolding auxiliary plate 54 and pushes the connecting column 55 and the inner plate 56, so that the inner plate 56 pushes the rubber plug that has been formed above it upward. When the demolding auxiliary plate 54 enters the positioning groove 11, the rubber plug is just completely pushed out, realizing automated demolding, and the demolding process (the height that the inner plate 56 needs to rise during demolding) can be precisely controlled.
