Problems solved by technology

[0002] With the rapid development of electronic technology, the requirements for injection molding are also diversified. At present, electronic products such as printers, banknote printing machines, and image sensors need glass and plastic molding products inside, and at the same time ensure that the glass and plastic have a certain tensile force. When the two sides are guaranteed to be flush with the surface of the plastic part, the glass and the plastic cannot be tightly bonded after molding; the glass reaches the state of clamping with the plastic after molding, and the height of the injection molded part is greater than the glass, resulting in the upper surface cannot be guaranteed to be on the same plane

Embodiment 1

[0022] refer to figure 1 As shown, this embodiment is a molding process of glass plastics. The first step: the insert in the male template is retracted to a height of 2mm into the male template, and the glass body is placed in the groove formed by the male template and the insert, and the male and female molds are combined. When molding, the upper surface of the entry and male formwork is flush, and the push block in the mother formwork presses the glass body by 0.05mm, the height of the cavity between the mother formwork and the male formwork is consistent with the glass body, and the push block is returned to be flush with the mother formwork; The second step: injection molding on both sides of the vitreous body. The compound material of PC and 30% GF is used for injection molding.

Abstract

The invention discloses a forming process of glass plastic. The forming process comprises the following steps that S1, an insert in a male template retracts into the male template to form a groove, a glass body is placed into the groove to be positioned, and when the male template and a female template are closed, the insert is flush with the upper surface of the male template, a push block in the female template presses the glass body by 0.05 mm, a mold cavity between the female template and the male template is as high as the glass body, the push block retracts to be flush with the female template, and the thickness of the glass body is controlled to be 1.82-1.88 mm; and S2, injection molding is adopted for the two side of the glass body. By adoption of the forming process, glass is not prone to being separated from plastic, and the surface of the glass plastic has no segment difference.
