Description

Technical Field

[0001] The utility model relates to the technical field of rubber vulcanizing machines, in particular to a rubber vulcanizing machine which is convenient for replacing molds. Background Art

[0002] A vulcanizing machine is a machine that vulcanizes various rubber and plastic products. It has functions such as timed mold locking, automatic pressure replenishment, automatic temperature control, automatic timing, and time alarm. The rubber lining is the rubber material lining at both ends and the cylinder used by the ball mill. A mold will be installed on the vulcanizing machine to process the rubber lining.

[0003] After the vulcanizer uses the mold to process the rubber lining, in order to maintain or clean the mold, the mold will be removed from the vulcanizer. The mold and the vulcanizer are connected by a large number of bolts. When the mold needs to be disassembled, the operator needs to use auxiliary tools to remove all the bolts. This connection method has the following shortcomings when used: the vulcanizer will vibrate continuously during operation, and the nuts of the bolts are very likely to slip when the bolts vibrate continuously, which causes the mold to vibrate significantly or fall off during operation; the bolts need to be constantly disassembled and assembled during disassembly and assembly of the mold, which takes a lot of time to disassemble and assemble the mold. The bolt connection method not only makes the stability of the mold unable to be guaranteed, but also affects the efficiency of mold assembly. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figures 1-4 A rubber vulcanizer that is easy to replace molds includes a vulcanizer body 1, and a mold body 2 for processing a rubber liner is provided on the vulcanizer body 1. When the vulcanizer body 1 is powered on, the mold body 2 is driven to process the rubber liner. This technical solution is a prior art and will not be elaborated on here. A frame 4 is fixedly mounted on the vulcanizer body 1, and a positioning rod 11 extending into the mold body 2 is provided in the frame 4 through a pressure member. By arranging the frame 4 on the vulcanizer body 1, the frame 4 can preliminarily define the position of the mold body 2.

[0022] The pressure member includes a movable plate 9 that is slidably sleeved in the frame 4, and a spring 10 is welded between the movable plate 9 and the frame 4. The movable plate 9 is horizontally arranged at the positions on both sides of the frame 4 accordingly. The mold body 2 is provided with a positioning groove that cooperates with the positioning rod 11. A movable component for pulling the two movable plates 9 horizontally is provided in the frame 4. The spring 10 is horizontally welded. The frame 4 guides the movable plate 9 so that the movable plate 9 can smoothly pull the positioning rod 11 when moving. The spring 10 resets the movable plate 9. When the movable plate 9 is in an unloaded state, the spring 10 can drive the movable plate 9 and the positioning rod 11 back to the initial position;

[0023] The moving assembly includes a motor 12 fixedly mounted in the frame 4, and the output end of the motor 12 is fixedly connected to a bidirectional screw 13 rotatably mounted on the frame 4. The sliding sleeve on the bidirectional screw 13 is provided with two matching nuts 14. The sliding sleeve in the frame 4 is provided with a contact plate 15 that movably contacts the moving plate 9, and a connecting rod 16 is connected between the contact plate 15 and the two nuts 14.

[0024] Further explanation, when the bidirectional screw rod 13 rotates, it drives the two nuts 14 to move toward or in opposite directions. When the two nuts 14 move toward each other, they can interfere with the contact plate 15 through the connecting rod 16. The contact plate 15 can interfere with the movable plate 9. The movable plate 9 drives the positioning rod 11 to pass through the frame 4 and extend into the positioning groove, making it easier to install the mold body 2 on the vulcanizer body 1.

[0025] When the two nuts 14 move in opposite directions, the contact plate 15 can be extracted through the connecting rod 16. When the contact plate 15 moves, it is disconnected from the movable plate 9. The movable plate 9 drives the positioning rod 11 to be disconnected from the mold body 2, so that the mold body 2 can be quickly disassembled.

[0026] The bidirectional screw rod 13 is horizontally arranged between the two movable plates 9. The two ends of the connecting rod 16 are respectively connected to the nut 14 and the middle end of the contact plate 15 by a pin. A guide block is fixedly mounted on the nut 14. A guide rod for guiding the guide block is installed on the frame 4. The guide rod guides the guide block and thus limits the moving direction of the nut 14.

[0027] A symmetrically arranged lifting plate 3 is fixedly mounted on the mold body 2, and a locking structure for locking the position of the lifting plate 3 is provided on the vulcanizer body 1;

[0028] The locking structure includes a slider 6 slidably sleeved in the vulcanizer body 1, and a support frame 7 for supporting the lifting plate 3 is integrally connected between the two sliders 6. A pressure plate 8 for clamping the lifting plate 3 is fixedly installed on the support frame 7. The vulcanizer body 1 is provided with a slide groove 5 for guiding the slider 6. The support frame 7 is a concave structure, and an armrest is provided on the support frame 7. The pressure plate 8 is threadedly connected to a locking bolt connected to the vulcanizer body 1;

[0029] The support frame 7 is driven to move by the handrail, and the support frame 7 can lift the lifting plate 3 from both sides, and the pressure plate 8 can clamp the lifting plate 3 from the top position, thereby locking the position of the mold body 2 again.

[0030] The functional principle of this utility model can be explained through the following operation modes:

[0031] When the mold body 2 needs to be replaced;

[0032] Remove the locking bolt and manually extract the handrail, so that the handrail drives the two support frames 7 to move in the opposite direction. When the support frame 7 drives the slider 6 to slide in the slide groove 5, the support frame 7, the pressure plate 8 and the lifting plate 3 are disconnected;

[0033] The mold body 2 is supported by handrails;

[0034] The output end of the motor 12 drives the bidirectional screw 13 to rotate, and the bidirectional screw 13 drives the two nuts 14 to move toward or in opposite directions when rotating;

[0035] When the two nuts 14 move in opposite directions, the contact plate 15 is pulled by the connecting rod 16. The contact plate 15 is disconnected from the moving plate 9 when it moves. Under the action of the spring 10, the moving plate 9 drives the positioning rod 11 to disconnect from the positioning groove, so that the frame 4 is disconnected from the mold body 2.

[0036] Move the mold body 2 to one side using the handrail.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
