Description

Technical Field

[0001] The utility model relates to the field of rubber product vulcanization, in particular to an ejection mechanism of a vulcanizing machine used for manufacturing rubber products. Background Art

[0002] With the improvement of industrialization level, the diversification of rubber products has put forward more and higher requirements for rubber vulcanization equipment. For example, in order to improve work efficiency, more products are set in a mold for compression vulcanization molding, or some larger products need to be compressed and vulcanized at one time. In this way, the weight and volume of the mold need to be increased, making it more difficult to move the vulcanization molding mold. To move the mold smoothly, it is necessary to use the ejection mechanism of the rubber vulcanization equipment to push the mold out of the vulcanization equipment and then perform further mold opening and feeding operations.

[0003] After searching, the flat plate vulcanizer with publication number CN202121808013.3 specifically discloses a base plate, four corners of the base plate are fixedly connected with sliding rods, a lifting plate is vertically slidably connected on the sliding rods, a hydraulic cylinder for controlling the lifting plate to slide up and down on the sliding rods is arranged above the lifting plate, an upper heating plate is fixedly installed below the lifting plate, and a lower heating plate is arranged above the base plate. The beneficial effect is: the utility model adds a rotating mechanism, so that the motor drives the rotating rod to rotate, and utilizes the mutual meshing characteristics of the upper gear and the lower gear to drive the lower heating plate to flip. After the lower heating plate flips to thirty degrees, the lifting mechanism below is used to lift the support frame upward to support the middle part of the lower heating plate, and the push block above the support frame is used to push the movable block upward, so as to push the rubber material out of the heating tank, which is convenient for taking the material.

[0004] However, the above device still has certain defects. For example, the device pushes up the rubber product through the electric cylinder and the push plate. The middle position of the rubber product is pushed up, while the edge position is still adhered to the heating plate. When the electric cylinder is retracted, the rubber product is easy to fall with the push plate, so it is not easy to push out the rubber product, and the practicality is low.

[0005] Therefore, it is necessary to invent a kind of ejection mechanism of the vulcanizing machine that is used for rubber product manufacturing to solve the above problems. Utility Model Content

An elastic metal strip 13 is bolted to the back side of the upper template 3, and ratchets 14 are provided on the right side of the elastic metal strip 13. The first electric cylinder 15 is bolted to both sides of the top of the mounting frame 2, and the bottom of the first electric cylinder 15 passes through the mounting frame 2 and is bolted to the top of the upper template 3.

[0027] A second electric cylinder 17 is bolted to the center of the top of the mounting frame 2 , and a housing 18 is bolted to the bottom of the second electric cylinder 17 through the mounting frame 2 . The effective height of the housing 18 can be quickly adjusted by driving the second electric cylinder 17 .

[0028] Slide grooves 19 are bolted on both sides of the top and bottom of the inner cavity of the shell 18, and a rack 20 is slidably connected to the inner side of the slide groove 19. Push plates 21 are bolted on both sides of the rack 20 through the shell 18. Rotating rods 22 are rotatably connected to both sides of the inner cavity of the shell 18 through bearings. A driving gear 23 is bolted on the surface of the rotating rod 22, and the surface of the driving gear 23 meshes with the surface of the rack 20. Servo motors 24 are bolted on both sides of the front of the shell 18, and the front of the rotating rod 22 passes through the shell 18 and is bolted to the output end of the servo motor 24.

[0029] A through slot 25 is formed on the inner sides of the lower template 4 and the top of the shell 5 , and the surface of the connecting rod 9 is slidably connected to the inner side of the through slot 25 .

[0031] Refer to the instruction manual Figure 1-5 Working principle: In the utility model, the vertical movement of the upper template 3 on the mounting frame 2 can synchronously drive the elastic metal strip 13 and the ratchet 14 to move vertically. When the upper template 3 descends and fits with the lower template 4, the meshing directions of the ratchet 14 and the ratchet wheel 12 are opposite, and thus no effect occurs. When the upper template 3 is separated from the lower template 4, the ratchet 14 actively hooks the ratchet wheel 12 and drives the ratchet wheel 12 to start rotating. When the ratchet wheel 12 starts to rotate, it synchronously drives the rotating shaft 10 to rotate. The rotating shaft 10 can drive the cam 11 to rotate during the rotation process. When the protruding part of the cam 11 rotates to vertically upward, the connecting plate 8 and the connecting rod 9 are lifted up, and at the same time, the rectangular separation plate 7 is also separated from the rectangular groove 6 and lifted upward, so that the rubber mold is separated from the upper surface of the lower template 4, and the cam 11 reciprocates to make the rectangular disengagement plate 7 move vertically quickly, so as to avoid incomplete disengagement caused by the sticking of the rubber mold. After the upper mold plate 3 moves and resets, the driving gear 23 is driven by the servo motor 24 to rotate, thereby driving the rack 20 and the push plate 21 to move horizontally. Since the bottom of the push plate 21 fits with the upper surface of the lower mold plate 4 after moving to the top of the lower mold plate 4, the rubber mold on the upper part of the lower mold plate 4 is pushed onto the transmission belts on both sides, and the rubber mold is transported to the subsequent processing area through the conveyor belt 16. When the rubber product is effectively stuck to the four sides of the lower mold plate 4, the rubber product can be quickly removed from the top of the lower mold plate 4, and the rubber product is pushed to the transmission component for transportation through the push plate 21, thereby improving the practicality of the ejection mechanism and the continuous vulcanization efficiency.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
