Transparent sheet overmolding

Abstract

The invention discloses a transparent plate encapsulation mould, which comprises a mould body, the mould body is provided with a forming die groove for transparent plate encapsulation, the mould body is provided with a positioning mechanism, an adsorption mechanism and a demoulding mechanism, and the positioning mechanism comprises several A positioning rod, a plurality of positioning rods are movably arranged on the side wall of the molding die groove according to a predetermined position, and the ends of the plurality of positioning rods are all protruding from the side wall, the mold body is provided with a telescopic assembly connected with the positioning rod, and the adsorption mechanism includes A suction cup and a support rod for air extraction. The suction cup is set in the forming die groove and connected with the support rod. The mold body includes a top plate connected with the support rod. The demolding mechanism includes a top block and a turning assembly. On the side wall of the groove, the overturning assembly includes a rotating shaft and a rotating block, and the rotating block is connected with the rotating shaft in a limited position. The present invention has simple structure and ingenious design, and improves the quality of the transparent plate by adding a positioning mechanism and an adsorption mechanism in the mold body.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a transparent sheet material overmolding mold. Background technique [0002] Transparent sheets (such as polycarbonate) are now used in automotive windows. In the production process, transparent sheets are the same as traditional car window glass, and the edges of the sheet need to be glued. Traditionally, the window glass is covered by The injection mold is used to complete the process. Therefore, the technician wants to use the traditional injection mold to encapsulate the transparent plate, but the traditional injection mold has the following problems: 1. There is no positioning mechanism in the injection mold, and there is a deviation in the placement of the transparent plate. 2. There is no mechanism for fixing the transparent sheet in the injection mold. During the encapsulation process of the transparent sheet, due to the existence of injection pressure, the position of the ...

There is no positioning mechanism in the injection mold, and there is a deviation in the placement of the transparent plate. 2. There is no mechanism for fixing the transparent sheet in the injection mold. During the encapsulation process of the transparent sheet, due to the existence of injection pressure, the position of the transparent sheet is prone to shift, resulting in encapsulation. The thickness of the glue on the edge of the glued transparent board is uneven
