[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] See also Figure 1-4 As shown, this embodiment provides a demoulding device for producing top glue, including a mounting frame 1, a support frame 2 is fixedly installed on the top of the mounting frame 1, connecting plates 3 are slidably installed on both sides of the supporting frame 2, a slide groove 4 is provided at the bottom of the connecting plate 3, a lifting plate 5 is slidably installed on the inner side of the mounting frame 1, and both ends of the lifting plate 5 extending to the outer side of the mounting frame 1 are respectively slidably connected with two connecting plates 3 through the slide groove 4, a lifting plate 26 is fixedly installed between the two connecting plates 3, and a liquid is installed on the top of the supporting frame 2 to drive the lifting plate 26 to move in the vertical direction. A pressing cylinder, a stamping die 7 adapted to the top glue stamping part is fixedly installed at the bottom of the lifting plate 6, a plurality of mounting grooves 8 adapted to the top glue stamping part are opened at the position corresponding to the stamping die 7 on the top of the mounting frame 1, a plurality of cutting components 9 arranged in intervals with the mounting grooves 8 are installed on the lifting plate 6, that is, a cutting component 9 is arranged between every two adjacent mounting grooves 8, a support plate 10 is fixedly installed below the mounting frame 1 adjacent to the plurality of mounting grooves 8, and demoulding components 11 are provided at the positions corresponding to the plurality of mounting grooves 8 on the support plate 10;

[0026] When the lifting plate 2 6 moves in the vertical direction, the connecting plate 2 92 drives the slide groove 4 to slide on the end of the lifting plate 1 5 until the end of the slide groove 4 abuts against the end of the lifting plate 1 5. Then the lifting plate 2 6 drives the lifting plate 1 5 to move synchronously through the connecting plate 1 3. Through the above operation, when the top glue stamping part is demoulded, the lifting plate 2 6 will drive the stamping die 7 to separate from the surface of the top glue stamping part, so as to prevent the stamping die 7 from hindering the demoulding of the top glue stamping part.

[0027] The cutting assembly 9 includes a slide bar 91 which is slidably installed on one side of the top of the mounting frame 1, and a connecting plate 92 is rotatably installed on one end of the slide bar 91 away from the mounting groove 8, and an end of the connecting plate 92 away from the slide bar 91 is rotatably connected to one side of the lifting plate 6, and a roller 93 is rotatably installed on the other end of the slide bar 91, and a plurality of piercing rods 94 are slidably installed on the outer peripheral wall of the roller 93, and a spring 95 which is sleeved on the outer peripheral wall of the piercing rod 94 is fixedly installed between one end of the piercing rod 94 and the inner peripheral wall of the roller 93, and the other end of the piercing rod 94 is configured to be conical in shape;

[0028] When the lifting plate 2 6 moves downward, it will pull the slide bar 91 away from the mounting groove 8 through the connecting plate 2 92, so that the slide bar 91 drives the roller 93 to move from one side of the mounting frame 1 to the other side along the two adjacent mounting grooves 8. During the movement of the roller 93, the piercing rod 94 on the outer peripheral wall is pressed against the top of the mounting frame 1 by the traction of the spring 95. The resistance at the top of the mounting frame 1 will drive the roller 93 to rotate at the end of the slide bar 91 through the piercing rod 94, so that the roller 93 drives a plurality of piercing rods 94 to roll on the mounting frame 1. When the travel path of the roller 93 is uneven, the piercing rod 94 will correct the position relationship in real time by squeezing the spring 95 to avoid the roller 93 being hindered when moving. When the lifting plate 2 6 moves upward, the moving direction of the roller 93 is just the opposite, so as to pierce holes in the laminated rubber, so as to facilitate the cutting of the laminated rubber on multiple top rubber stamping parts.

[0029] The demoulding assembly 11 includes a top cylinder 111 which is slidably installed on the support plate 10, an air outlet is opened on the top of the top cylinder 111, a sealing ring 112 is fixedly installed at the position corresponding to the air outlet at the bottom of the mounting groove 8, and the sealing ring 112 is made of rubber material. A top rod 113 is slidably installed on the bottom end of the top cylinder 111, and the bottom end of the top rod 113 is fixedly connected to the top of the lifting plate 5. A piston 114 which fits the inner wall of the top cylinder 111 is fixedly installed on the outer peripheral wall of the top rod 113, and the piston 114 is made of rubber material. When the piston 114 slides on the inner wall of the top cylinder 111, there is a certain damping, and a baffle 115 is fixedly installed on the outer peripheral wall of the top cylinder 111 near the position above the support plate 10;

[0030] The movement of the lifting plate will drive the push rod 113 to move upward synchronously. Since the piston 114 has a certain damping when sliding on the inner circumferential wall of the top cylinder 111, the push rod 113 will drive the top cylinder 111 to move upward through the piston 114 until the top of the top cylinder 111 abuts against the sealing ring 112 at the bottom of the mounting groove 8, and the push rod 113 will drive the piston 114 to slide upward on the inner circumferential wall of the top cylinder 111, so that the piston 114 first discharges the air in the top cylinder 111 into the mounting groove 8, and then the top end of the push rod 113 passes through the air outlet and pushes against the top rubber stamping part in the mounting groove 8 to eject the top rubber stamping part. When the lifting plate drives the push rod 113 to move downward, the top cylinder 111 will also move downward with the push rod 113 for an end distance until the baffle 115 abuts against the top of the support plate 10, and the push rod 113 drives the piston 114 to move downward in the top cylinder 111;

[0031] When the utility model is in use, firstly, a plurality of top glue stamping parts to be processed are respectively installed in a plurality of installation grooves 8, and then the rubber block is placed on the top of the plurality of top glue stamping parts, so that the lifting plate 2 6 drives the stamping die 7 to move downward, at this time, the lifting plate 2 6 drives the connecting plate 1 3 to move downward for a distance before driving the lifting plate 1 5 to move downward synchronously, until the lifting plate 2 6 pulls the slide bar 91 and the roller 93 out of the right below the stamping die 7 through the connecting plate 2 92, and the stamping die 7 just presses the rubber block on the plurality of top glue stamping parts, and then moves the lifting plate 2 6 upward, and when the stamping die 7 is released, the rubber block is pressed onto the plurality of top glue stamping parts. After the top of the top rubber stamping part is away and multiple cutting components 9 have pierced holes in the rubber surface between two adjacent mounting grooves 8, the lifting plate 2 6 drives the lifting plate 1 5 to move upward through the connecting plate 1 3, and the lifting plate 1 5 moving upward simultaneously drives multiple ejector rods 113 to move upward, so that the demoulding component 11 first supplies gas into the mounting groove 8 and then pushes in the ejector rod 113, so that the gas will flush the rubber adhered to the mounting frame 1, and then the top rubber stamping part will be pushed out of the mounting groove 8 through the ejector rod 113, and finally the rubber between the ejected multiple top rubber stamping parts will be pulled apart through the pierced holes.
