Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lining plate processing, and in particular relates to a glue discharge structure of a steel-glue composite lining plate production mold. Background Art
[0002] The liner is an anti-collision structural component used in the ball mill, which can effectively reduce the impact damage of the grinding medium on the side wall of the ball mill cylinder. The steel-rubber composite liner is a material liner that can not only reduce the weight of the liner, but also reduce the sound when the grinding medium impacts, greatly reducing noise pollution. This kind of steel-rubber composite liner needs to be vulcanized in the mold during production.
[0003] When producing steel-rubber composite linings through molds, in order to ensure the molding effect of the mold, it is necessary to discharge the excess rubber inside the mold under pressure. Therefore, a rubber discharge channel is usually provided inside the mold. By connecting with the rubber discharge head, it can prevent the rubber from being discharged too quickly and too much, and can smoothly discharge the excess rubber to the outside, thereby reducing the pressure inside the mold and allowing the rubber to fill the entire mold.
[0004] like Figure 7 As shown, since the vulcanization section is a high-temperature process, after the insert-type degumming head is heated to 160°C, the rubber will undergo a chemical reaction at this temperature to harden it. In order to prevent blockage, two through holes are arranged inside the degumming head, one of which is smaller and shorter and is connected to the degumming channel inside the mold, and the other is larger and longer and is connected to the smaller through hole. The diameter and length of the small hole are widened through the larger and longer through hole, reducing the travel of the discharged rubber inside the small hole, and avoiding the blockage of the holes in the degumming head and the inability to discharge glue after the rubber is directly vulcanized.
[0005] In the current existing technical solutions, the small hole is set in the middle of the large hole (such as Figure 7 As shown in the figure, after the rubber enters the large hole from the small hole, it droops into the inside of the large hole, resulting in a small amount of rubber being unable to be quickly discharged at the connection between the large hole and the small hole. At this time, due to the high temperature here, the rubber is vulcanized and hardened, causing slight blockage, resulting in poor debonding effect of the debonding head and poor debonding, which affects the size, appearance and quality of the product. Utility Model Content
