Feeding device for injection molding silicone mold insert

Abstract

The invention discloses a feeding device for an injection molding silicone mold insert. The feeding device comprises a tool bottom mold and a thimble plate. The tool bottom mold is provided with positioning bosses, so that the to-be-fed plastic insert can be quickly positioned on the tool bottom mold and precisely sucked by a suction cup assembly; after the plastic insert is positioned on the tool bottom mold, a hand holds a tool handle to transfer the plastic insert to an injection mold; after the plastic insert and the injection mold are precisely positioned through positioning columns, the suction cup assembly is changed to loosen the plastic insert, and the hand presses the tool handle and lifts a bottom mold traction handle, so that the tool bottom mold gets close to the thimble plate; under the guide effect of an elastic guide assembly, thimbles are sleeved with material ejection through holes and completely eject the plastic insert into the mold; and finally, the hand holds the tool handle to take the tool bottom mold and the thimble plate away from the injection mold, feeding of the plastic insert is completed, after the bottom mold traction handle is loosened, the tool bottom mold is reset, and the next time of feeding can be conducted. Thus, by using the feeding device for the injection molding silicone mold insert, the production efficiency can be improved, and the safety of operation staff is ensured.

Description

technical field [0001] The invention relates to the technical field of silicone mold injection molding, in particular to a feeding device for injection molding silicone mold inserts. Background technique [0002] With the development of the electronics industry, there are more and more types of injection molding products, and the injection molding process of silicone molds is becoming more and more complicated. In the current state, silicone molds are mostly produced on vertical injection molding machines, which cannot cooperate with manipulators to make fixtures and realize automatic loading. Most of the current vertical injection molding machines use manual mold tooling to manually load the inserts. For metal magnetic inserts, the tooling can bury the magnets on the bottom mold surface to absorb the inserts. After the positioning pin is positioned, it cooperates with the mold, and the thimble ejects the inserts to the mold to complete the loading. However, for plastic in...

Problems solved by technology

However, for plastic inserts, the manual tooling of the mold cannot be adsorbed by magnets, nor can it be positioned by positioning pins. Moreover, due to the high temperature of the mold during production, the inserts are loaded manually by the operator, which is not only inefficient, but also There is a risk of being scalded by the hot mold
