Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of molding equipment, in particular to a high-efficiency molding equipment and a using method thereof. BACKGROUND

[0002] Molding is the abbreviation of compression molding, which belongs to the molding process of plastic and rubber products. Raw materials are placed in a mold, and the material is formed by heating and pressing. In the production of rubber sheets, molding equipment is often used.

[0003] Because the material forming needs to be kept warm and pressurized for a certain period of time during the molding process, a certain period of time is needed after the two molds are closed. The time required for molding is usually related to the thickness of the product and the type of material. Because the rubber sheet is relatively thin, the time required for molding is relatively short.

[0004] In the prior art, when using a conventional molding equipment to produce rubber sheets, the general process is as follows: feeding, closing the mold, molding vulcanization, opening the mold, and demolding operation. During the molding vulcanization process, subsequent operations cannot be performed, and only waiting for the completion of the molding vulcanization can be performed. Therefore, the production efficiency of rubber products is reduced. In addition, because the precision required for rubber sheets is low, in order to reduce costs, the precision of the mold is reduced, the long-term use of the mold causes the gap between the molds to be large, and when placing the raw materials, more raw materials are generally placed to meet the shrinkage compensation. Therefore, after molding, the rubber sheets are connected by flash, and after demolding, a large amount of trimming work is required, further reducing the molding efficiency. SUMMARY

[0137] Step four: after a certain time of pressure and temperature keeping, the lifting seat 103 is driven to rise by hydraulic push rod 105, and then the lower mould 302 completed moulding is pushed away from the lifting seat 103 by the work of electric push rod 902, at the same time, the lower mould 302 placing raw material moves to the position below the lifting seat 103;

[0138] Step 5: The hydraulic push rod 105 drives the lifting seat 103 to descend again to carry out the molding and vulcanization treatment of the rubber raw material on another lower mold 302. During this process, the lifting seat 103 descends through the connecting beam 401 so that the rod body 402 slides downward along the connecting block 501, so as to drive the first bracket 502 to descend through the second spring 403. When the first bracket 502 descends, the second bracket 601 is driven to descend through the third spring 604, thereby driving the sleeve 701 and the sleeve rod 702 to descend. When the rubber block 703 at the bottom of the sleeve rod 702 contacts the lower mold 302, as the lifting seat 103 continues to descend, the second spring 403 and the third spring 604 are both stretched. Subsequently, by controlling the flow control valve 704, the gas in the sleeve 701 is discharged at a certain speed, cooperating with the stretched second spring 403 and the third spring 604, so that the second bracket 601 slowly descends. At this time, the switch of the air pump is turned on, and the three-way valve 803 is controlled to allow the gas to pass through the three-way valve 803. The hose 802 and the three-way valve 803 enter the second tube 805, and then enter each knife seat 505 through the connecting pipe 506, so that the gas is output from the bottom of the knife seat 505 and blown to the rubber sheet after the mold above the lower mold 302. The air flow is used to cool the rubber sheet and the flash, accelerating the cooling and solidification of the rubber sheet and the gasket. When the sleeve rod 702 is fully extended into the sleeve 701, the suction cup 606 is in contact with the flash between each rubber sheet, and the suction cup 606 is used to cool the rubber sheet and the flash. Then, by controlling the three-way valve 803, the gas in the three-way hose 802 enters the first tube 804 through the three-way valve 803 and then enters the sleeve 701, so that the air pressure in the sleeve 701 increases. With the action of the piston 705, the sleeve rod 702 is extended from the sleeve 701, thereby achieving the rise of the second bracket 601, so that the second bracket 601 and the connecting block 501 are away from the lower mold 302. At this time, the rubber raw material can be placed on the lower mold 302;

[0139] Step six: after the mold pressing vulcanization, the lifting seat 103 needs to be driven to rise again by the hydraulic push rod 105, so that the other lower mold 302 moves to the lower side of the lifting seat 103, and the mold pressing vulcanization process is carried out again. At this time, when the lifting seat 103 is lowered, the connecting cylinder 503 enters the circular groove 306, and the sliding rod 602 abuts against the bottom of the circular groove 306, so as to realize the mutual far away of the second support 601 and the first support 502. At this time, the suction cup 606 is raised compared to the cutting seat 301, and the annular knife 508 is lowered compared to the cutting seat 301. When the annular knife 508 enters the through hole 307, the rubber sheet can be cut off. The gas is introduced into the knife seat 505 again, so that the cut rubber sheet is flushed out of the knife seat 505 and the through hole 307 by the gas. Finally, the switch of the electromagnetic valve 607 is turned on. The external gas enters the suction cup 606 through the electromagnetic valve 607 and the connecting pipe 605, so as to leave the rubber flash at the bottom of the suction cup 606 on the cutting seat 301. When the rubber raw material is placed on the side of the lower mold 302, the rubber flash on the cutting seat 301 can be removed.
