[0002] Ethylene propylene diene monomer rubber (EPDM) is an important rubber material, which is widely used in the automotive, electronic and electrical industries. Adding halogen-free flame retardants to (EPDM) is a way to improve the flame retardant properties of EPDM. The halogen-free flame retardants widely used in Europe, the United States and Japan are metal hydroxides mainly composed of aluminum hydroxide Al(OH)3 and magnesium hydroxide Mg(OH)2. The flame retardant mechanism of Al(OH)3 and Mg(OH)2 is the same: their high-temperature decomposition reaction is an endothermic reaction, which can absorb part of the combustion heat; the large amount of water vapor released can dilute the concentration of combustible gas; the metal oxides produced by combustion become the main component of the carbon layer, which can delay the entry of heat and oxygen into the flame-retardant polymer material matrix. Therefore, the addition of Al(OH)3 and Mg(OH)2 can delay the thermal degradation rate of EPDM, slow down and inhibit the combustion of polymers, and promote carbonization and smoke suppression. In the production of rubber foot pads, clamping devices are used.

[0003] The ambient temperature of the existing rubber product molds is 60 to 70 degrees. The weight of agricultural machinery foot pads is relatively large, and the adsorption force of rubber and molds is high. Manual operation is not only labor-intensive but also inefficient.

The lower ends of the upper hinges 7 are provided with lower hinges 9 on the grabbing plate 2. Before use, the movable sliders 10 are connected to the external racks through the rack connection blocks 4 for lifting after clamping. During use, after the grabbing claws 8 grab the foot pad product 1, the two connection components 3 are simultaneously withdrawn, and the entire grabbing plate 2 can perform a selection action. At the same time, the upper hinges 7 are connected to the movable sliders 10, and the movable sliders 10 By moving the slide rail inward, the grabbing claw 8 below the grabbing plate 2 grabs the foot pad product 1 and makes the same movement. Because the grabbing plate 2 makes a rotating motion, it grabs the outer edge of the foot pad product 1 from the farthest end and lifts up the flash of the foot pad product 1 to let air in, destroying the vacuum environment when the rubber and the lower mold are tightly adsorbed, and then pulls the foot pad product 1 from the outside to the inside. When the connecting component 3 has reached its stroke, the sensor 34 at the upper end of the connecting component 3 will sense it and output a signal to the PLC, and the PLC will control the frame to lift upward to complete the work of separating the middle section of the product from the mold, so that the entire product is separated from the mold. After lifting to a certain distance, the large oil cylinder is pushed out again, and the entire grabbing fixture is flattened. When the sensor 34 at the lower end of the large cylinder detects a signal, it indicates that the cylinder core has been pushed to the bottom, and the signal is transmitted to the PLC again. The PLC gives an instruction to move the frame out of the press, thereby realizing mechanical demolding. The mechanization of product handling in this way greatly improves work efficiency and liberates manpower.

[0020] In the utility model, the connecting assembly 3 includes a connecting base 31, a metal connecting rod 32, a driving cylinder 33, a sensor 34 and a connecting shaft 35.

The connection of the base 31 is connected by a connecting shaft 35, so that it is convenient to rotate when in use. When in use, the sensor 34 will output a signal to the PLC, and the PLC will control the frame to lift upward to complete the work of separating the middle section of the product from the mold, so that the entire product is separated from the mold. After lifting to a certain distance, the driving cylinder 33 is pushed out again, and the entire grasping fixture is flattened. When the sensor 34 at the lower end of the driving cylinder 33 detects a signal, it indicates that the core of the driving cylinder 33 has been pushed to the bottom, and the signal is transmitted to the PLC again. The PLC gives an instruction to move the frame out of the press, thereby realizing mechanical demolding. The mechanization of product handling greatly improves work efficiency and liberates manpower.

[0021] In the utility model, two cylinder connecting plates 5 are provided, and the cylinder connecting plates 5 are symmetrically connected to both sides of the upper end of the mounting frame 6.

[0024] Working principle: Before use, it is connected to the external frame through the frame connecting block 4 for lifting after clamping. During use, after the grabbing claw 8 grabs the foot pad product 1, the two connecting components 3 are withdrawn at the same time, and the entire grabbing plate 2 can make a selection action. At the same time, the upper hinge 7 is connected to the moving slider 10, and the moving slider 10 moves inward through the slide rail, and the grabbing claw 8 below the grabbing plate 2 grabs the foot pad product 1 and makes the same movement. Because the grabbing plate 2 makes a rotational motion, it grabs the outer edge of the foot pad product 1 from the farthest end to lift the flash of the foot pad product 1, let the air in, destroy the vacuum environment when the rubber and the lower mold are tightly adsorbed, and then pull it open from the outside to the inside. Foot pad product 1, when the connecting component 3 has reached its stroke, the sensor 34 at the upper end of the connecting component 3 will sense it and output a signal to the PLC, and the PLC will control the carriage to lift upward to complete the work of separating the middle section of the product from the mold, so that the entire product is separated from the mold. After lifting to a certain distance, the large cylinder is pushed out again, and the entire grasping fixture is flattened. When the sensor 34 at the lower end of the large cylinder detects a signal, it indicates that the cylinder core has been pushed to the bottom, and the signal is transmitted to the PLC again. The PLC gives an instruction to move the carriage out of the press, thereby realizing mechanical demolding. The use of mechanization to complete the handling of products greatly improves work efficiency and liberates manpower.
