[0002] A vulcanizer is a type of molding machine, which is applicable to the mixing and processing of polymers such as rubber and plastics industries, such as PVC, masterbatch and other chemical raw materials, and ingredient tests to detect whether the required color and quality are achieved. It can be used as a basis for ingredient preparation before factory mass production. During the vulcanization and shaping process of the product, the wound product is placed into the vulcanizer, and the product is closely attached to the die through heating, pressurization, inflation and other means.

[0003] When the product is placed into the vulcanizer for vulcanization and shaping, it is necessary to first put the product on the outside of the positioning part of the die, and then drive the clamping part to move, and the clamping part cooperates to fix the product on the outside of the positioning part. However, when the clamping part and the positioning part are separated after the product is vulcanized and shaped, when the staff slides the clamping part, it is easy to slide out and disengage from the slide rail inside the frame due to excessive force, which affects the work efficiency and brings inconvenience to the staff.

[0004] Therefore, to solve the above problems, a demoulding structure for a vulcanizer die is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a demoulding structure for a vulcanizer die, which has the advantages of sliding limit, etc., and solves the problem that when the clamping part and the positioning part are separated after the product is vulcanized and shaped, it is easy to slide out and disengage from the slide rail inside the frame due to excessive force when the staff slides the clamping part.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A demoulding structure for a vulcanizer die includes two frames. A fixed frame is arranged between the two frames. An extension rod is slidably arranged inside the frame. One ends of the two extension rods are provided with a strip.

[0007] The limiting component includes a baffle slidably arranged inside the extension rod. A guide rod is arranged inside the extension rod. A limiting plate is slidably arranged on the outside of the guide rod. A second spring is sleeved on the outside of the guide rod. A wire reel is rotatably arranged inside the extension rod. A pull rope is wound around the outside of the wire reel. Two pull rods are slidably arranged inside the strip. A first spring is sleeved on the outside of the pull rod.

[0008] Further, a plurality of positioning members are provided on both sides of the fixing frame, and a clamping member corresponding to the number of positioning members is provided on one side of the insert bar.

[0009] Further, two pulleys are rotatably provided inside the extension rod. The pulleys penetrate and extend to the outside of the extension rod, and the pulleys are in contact with a chute opened inside the machine frame.

[0010] Further, a limiting groove adapted to the width of the baffle is opened inside the machine frame, and one end of the baffle penetrates and extends to the outside of the extension rod.

[0011] Further, one end of the second spring is fixedly connected to the side of the limiting plate away from the baffle, and the other end of the second spring is fixedly connected to the inner wall of the extension rod.

[0012] Further, one end of the pull rope is fixedly connected to one side of the limiting plate, and the other end of the pull rope is fixedly connected to one end of the pull rod.

[0013] Further, a chute adapted to the width of the extension rod is opened inside the machine frame, and one end of the pull rod penetrates and extends to the inside of the extension rod.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , a demoulding structure of a vulcanizing machine mold in this embodiment includes two frames 1. A fixed frame 2 is arranged between the two frames 1. An extension rod 5 is slidably arranged inside the frame 1. A chute 17 adapted to the width of the extension rod 5 is opened inside the frame 1. One end of each of the two extension rods 5 is provided with an insert strip 4. A limiting component is arranged on the extension rod 5;

[0025] The limiting component includes a baffle 10 slidably arranged inside the extension rod 5. A guide rod 12 is arranged inside the extension rod 5. A limit plate 13 is slidably arranged on the outer side of the guide rod 12. A second spring 14 is sleeved on the outer side of the guide rod 12. A wire reel 15 is rotatably arranged inside the extension rod 5. A pull rope 16 is wound around the outer side of the wire reel 15. Two pull rods 7 are slidably arranged inside the insert strip 4. A first spring 8 is sleeved on the outer side of the pull rod 7.

[0026] Among them, a plurality of positioning members 3 are arranged on both sides of the fixed frame 2. A clamping member 6 corresponding to the number of the positioning members 3 is arranged on one side of the insert strip 4. Two pulleys 9 are rotatably arranged inside the extension rod 5. The pulleys 9 penetrate and extend to the outside of the extension rod 5. The pulleys 9 are in contact with the chute 17 opened inside the frame 1. By sliding the pulleys 9 in the chute 17 opened inside the frame 1, it is convenient for the extension rod 5 to move inside the frame 1.

[0027] In addition, a limiting groove 11 adapted to the width of the baffle 10 is provided inside the frame 1. One end of the baffle 10 penetrates and extends to the outside of the extension rod 5. Through the arrangement of the baffle 10, during the movement of the extension rod 5, the baffle 10 slides inside the limiting groove 11, so that the movement range of the extension rod 5 can be restricted, thereby reducing the situation that the extension rod 5 slides out of the frame 1 and detaches.

[0028] It should be noted that one end of the second spring 14 is fixedly connected to the side of the limiting plate 13 away from the baffle 10, the other end of the second spring 14 is fixedly connected to the inner wall of the extension rod 5, one end of the pulling rope 16 is fixedly connected to one side of the limiting plate 13, the other end of the pulling rope 16 is fixedly connected to one end of the pull rod 7, one end of the pull rod 7 penetrates and extends to the inside of the extension rod 5, and one end of the first spring 8 is fixedly connected to one side of the insert strip 4, and the other end of the first spring 8 is fixedly connected to the outside of the pull rod 7.

[0029] During actual use, the guide rod 12 can guide the limiting plate 13, so that the baffle 10 moves in the vertical direction. Through the arrangement of the limiting plate 13, the position of the baffle 10 can be restricted. When the pull rod 7 is pulled to move, the first spring 8 will deform. When the pulling rope 16 pulls the limiting plate 13 to move, the limiting plate 13 will squeeze the second spring 14 to make it deform. Through the arrangement of the first spring 8 and the second spring 14, when the pull rod 7 is released, the pull rod 7 and the baffle 10 can be driven to reset.

[0030] It should be noted that by setting the limiting component, after the vulcanization and shaping treatment of the product is completed, the clamping member 6 is slid to separate it from the positioning member 3. Through the arrangement of the baffle 10, during the sliding of the extension rod 5, the baffle 10 slides inside the limiting groove 11, which can limit the sliding distance of the extension rod 5, and reduce the situation that the extension rod 5 slides out of the frame 1 and detaches due to excessive force of the staff when taking out the vulcanized and shaped product, which is convenient for the user to use.

[0031] The working principle of the above embodiment is as follows:

[0032] When the product is vulcanized and shaped, the product is sleeved on the outside of the positioning member 3, and then the insert strip 4 is pushed to slide through the pulley 9 on the extension rod 5 in the chute 17 opened inside the frame 1, so that the clamping member 6 moves toward the side close to the positioning member 3, and the clamping member 6 and the positioning member 3 cooperate to clamp and limit the product, which is convenient for subsequently feeding the product into a vulcanizer for vulcanization and shaping. After the vulcanization and shaping of the product is completed, the staff pulls the insert strip 4 to drive the extension rod 5 to slide through the pulley 9, so that the clamping member 6 slides to separate from the positioning member 3, which is convenient for taking out the product after the vulcanization and shaping. Through the arrangement of the baffle 10, the baffle 10 slides inside the limit groove 11 during the sliding process of the extension rod 5, and the sliding distance of the extension rod 5 can be limited, reducing the situation that the extension rod 5 slides out of the inside of the frame 1 due to excessive force of the staff when taking out the product after vulcanization and shaping. In addition, when the extension rod 5 needs to be taken out of the inside of the frame 1, the pull rod 7 is pulled to drive the pull rope 16 to move, and one end of the pull rope 16 pulls the limit plate 13 to slide on the outside of the guide rod 12, and the baffle 10 is retracted into the inside of the extension rod 5, so that the extension rod 5 is no longer restricted, which is convenient for sliding the extension rod 5 out of the inside of the frame 1 and convenient for the user to use.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
