[0024] As can be fully understood by those skilled in the art, the features of different embodiments of the present disclosure can be partially or fully coupled or combined with each other, and can cooperate with each other in various ways and be technically driven. The embodiments of the present disclosure can be executed independently of each other, or can be executed together in a mutually dependent relationship.

[0025] Referring to Figures 1 to 3 , the present utility model discloses a safety pin device for a special vulcanization forming machine for a wire saw, including an upper template 1 and a fixed template 2. A safety guide rod 3 is provided on the upper template 1, and a pin head 4 and a safety oil cylinder are provided on the fixed template 2. The safety oil cylinder includes a cylinder body, a piston rod disposed in the cylinder body, and an elastic member 5. The piston rod of the safety oil cylinder is connected to the pin head 4, and the elastic member 5 can push the piston rod to drive the pin head 4 to engage with the safety guide rod 3. Specifically, the piston rod includes a reciprocating rod 6 and a piston 7 fixed to the reciprocating rod 6. The pin head 4 is connected and fixed to the reciprocating rod 6 by a thread. The cavity in the cylinder body is separated into an oil cavity 8 and an installation cavity 9 by the piston 7. The oil cavity 8 is communicated with an oil circuit through a pipeline. The elastic member 5 is located in the installation cavity 9 and can push the piston 7. Through the design of the above structure, under normal circumstances, the oil cavity 8 is filled with oil, and the pressure of the oil is balanced with the elastic force of the elastic member 5, so the piston rod will not move. When there is a problem with the oil circuit, the piston rod loses the balance of the oil pressure, and the elastic member 5 can push the piston rod to drive the pin head 4 to engage with the safety guide rod 3, thereby preventing the fall of the upper template 1.

[0026] As shown in the figure, a guide rod 10 is fixed on the piston 7, and the elastic member 5 is a spring. The spring is arranged on the guide rod 10. The above structure ensures that the spring can apply an elastic force to the piston 7 along the guide rod 10.

[0027] As shown in the figure, for the convenience of processing, the cylinder block includes an oil cylinder front cover 11, a reset cylinder barrel 12, and an oil cylinder rear cover 13. The oil cylinder front cover 11 has an inner cavity and a first front cover hole and a second front cover hole 14 that communicate with the inner cavity and the outside. The reset cylinder barrel 12 is connected to the second front cover hole 14 by a thread. The reciprocating rod 6 can extend through the first front cover hole to be engaged with the safety guide rod 3. There is a sealing ring between the reciprocating rod 6 and the first front cover hole. Of course, there is also a sealing ring between the reset cylinder barrel 12 and the oil cylinder front cover 11. The piston 7 is in sealing contact with the reset cylinder barrel 12, so that the oil cavity 8 becomes a sealed cavity. Of course, there is also an oil hole on the oil cylinder front cover 11 that communicates with the oil cavity 8. The oil hole is connected to an oil pipe through a pipe joint. One end of the spring abuts against the piston 7 and the other end abuts against the bottom end of the oil cylinder rear cover 13.

[0028] As shown in the figure, a through hole is provided at the bottom end of the cylinder block. Specifically, the through hole is at the bottom end of the oil cylinder rear cover 13. One end of the guide rod 10 extends out of the through hole. A proximity switch 15 capable of sensing the guide rod 10 is provided on the fixed template 2. Usually, the guide rod 10 is in contact with the proximity switch 15. When there is a problem with the oil circuit, after the piston rod and the guide rod 10 are pushed and moved by the elastic member 5, the guide rod 10 disengages from the proximity switch 15, and the proximity switch 15 will send a signal to notify the control center and give an alarm.

[0029] As shown in the figure, a pin seat 16 is provided on the fixed template 2. A vertical hole 17 and a horizontal hole 18 are provided in the pin seat 16. The vertical hole 17 and the horizontal hole 18 communicate with each other. The safety guide rod 3 can move in the vertical hole 17, and the pin head 4 can move in the horizontal hole 18. Through the above structure, the vertical hole 17 can provide a support point for the safety guide rod 3 and does not affect the movement of the safety guide rod 3 along with the upper template 1. Of course, a plurality of card slots 21 are provided on the safety guide rod 3, and the pin head 4 can be inserted into the card slots 21. In this way, it can be ensured that within any movement range of the upper template 1, there will be a card slot 21 that can be engaged with the pin head 4 in case of a fall.

[0030] As a further preferred structure, a guide flange 19 is provided on the pin seat 16. A guide hole 20 communicating with the horizontal hole 18 is provided in the guide flange 19. The pin head 4 can be slidably matched with the guide hole 20. The guide hole 20 can provide a support point for the safety guide rod 3 and guide the pin head 4 to move in a straight line without deviation, thus ensuring the reliability of the engagement between the pin head 4 and the safety guide rod 3.

[0031] The above has introduced in detail a safety pin device for a special vulcanization forming machine for wire saws provided by the embodiments of the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
