Abstract
The invention discloses a pouring technique for a sealing plug pressing plate. A front die plate and a rear die plate are combined together by adjusting a limiting screw. A pouring pipe is fixed to the front die plate through a positioning ring. Glue liquor in the pouring pipe enters a pouring system through a pouring opening, then enters an annular passageway to flow towards the two sides and enters a cavity of a sealing plug core between a front die core and a rear die core from flue outlets in the two ends of the annular passageway. Heating fluid is injected into a heating hole to heat the pouring system, so that the pouring system is kept within a set temperature range. The temperature of a glue fluid bag in the pouring system is measured through a temperature measurement hole. The glue liquor enters the cavity through the pouring opening, and the glue in the cavity is cured into a finished sealing plug. The finished sealing plug is ejected out of the cavity of the sealing plug core through the front end of a push rod, so that a product and overflow materials fall into a pressing-out gap. The practicability is high, both installation and maintenance are quite convenient, the quality and the accuracy of the product are effectively guaranteed, the working efficiency is greatly improved, and the production cost is reduced.
