[0019] like Figure 1-4As shown, a cutting device for rubber product production includes a cutting table 1, a cylinder 4 and a cutting knife 7. Pillars 2 are welded at the four corners of the top surface of the cutting table 1. The top of the pillar 2 is fixedly connected to a top frame 3. The cylinder 4 is fixedly installed at the center of the top surface of the top frame 3, and the output end of the cylinder 4 is connected to a telescopic column 5. The bottom end of the telescopic column 5 is fixedly installed with a frame 6. The cutting knife 7 is fixedly installed on the bottom surface of the frame 6. Two groups of ejectors 15 are symmetrically arranged on both sides of the cutting knife 7. When working, driven by the cylinder 4, the telescopic column 5 will drive the frame 6 and the cutting knife 7 at the bottom thereof to move downward to cut the rubber part. Before the cutting knife 7 cuts, the ejectors 15 on both sides of the cutting knife 7 will first push against the rubber part to position it to avoid shaking of the rubber part during the cutting process and affecting the cutting stability.
[0020] In this embodiment, the ejector pin 15 is arranged to penetrate the guide cylinder 13 , a spring 14 is fixedly installed on the top of the guide cylinder 13 , a limit block 16 is installed on the top of the ejector pin 15 , and the bottom surface of the limit block 16 is fixedly connected to the top of the spring 14 .
[0021] Specifically, after the ejector pin 15 is pressed against the surface of the rubber part, the cutting knife 7 will continue to move downward for cutting, at which time the ejector pin 15 will push the spring 14 to move, and when the cutting knife 7 completes cutting and returns to its original position, the spring 14 will drive the ejector pin 15 to return to its original position to complete a cycle.
[0022] In this embodiment, the guide tube 13 is embedded in the inner wall of a slot provided on the guide seat 12 , and the guide seat 12 is threadedly connected to the outer wall of the bidirectional threaded rod 10 .
[0023] Specifically, the rotation of the bidirectional threaded rod 10 can drive the threaded guide seat 12 to move and adjust the position so as to position different rubber parts. The guide cylinder 13 is used to install the ejector pin 15 .
[0024] In this embodiment, the outer wall of the bidirectional threaded rod 10 is symmetrically provided with two sets of thread segments with opposite rotation directions, and the two sets of guide seats 12 located on the same side of the cutting knife 7 are symmetrically provided at the outer ends of the two sets of opposite thread segments.
[0025] Specifically, the rotation of the bidirectional threaded rod 10 can drive the two groups of guide seats 12 to move toward or in opposite directions at the same time, so as to achieve the purpose of adjusting the distance.

[0029] Specifically, the bidirectional threaded rod 10 is driven to rotate by rotating the turning handle 11 , so as to control the movement of the adjusting guide seat 12 .
[0030] It should be noted that the utility model is a cutting device for producing rubber products. When working, driven by the cylinder 4, the telescopic column 5 will drive the frame 6 and the cutting knife 7 at the bottom thereof to move downward to cut the rubber part. Before the cutting knife 7 cuts, the ejector pins 15 on both sides of the cutting knife 7 will first push against the rubber part to position it to avoid the rubber part shaking during the cutting process and affecting the cutting stability. After the ejector pins 15 push against the surface of the rubber part, the cutting knife 7 will continue to move downward for cutting. At this time, the ejector pins 15 will push the spring 14 to move. When the cutting knife 7 completes cutting and returns to its position, the spring 14 will drive the ejector pins 15 to return to its position to complete a cycle.
