Embodiment Construction

[0028] In the present invention, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings. However, it should be understood that these terms are mainly used to better describe the present invention and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation, and the present invention can also take various other orientations, so Such terms should not be construed as limiting.

[0029] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Such as Figure 1~4 As shown, a mold for integral injection molding of glass and nail posts according to the present invention is characterized in that: it includes an upper mold 1, a lower mold 2 and an insert 5 that can be lifted and lowered in the lower mold 2. The upper surfa...

Abstract

The invention relates to the technical field of moulds for injection molding, in particular to a mould for integral injection molding of glass and a nail column. The mould comprises an upper mould, alower mould and an insert arranged in the lower mould in a lifting manner, wherein a profiling surface used for fitting and placing glass is arranged on the upper surface of the lower mould, a steppedslot used for enabling the insert to be lifted is formed in the upper surface of the lower mould, a small slot of the stepped slot is arranged at one side close to the profiling surface, a large slotof the stepped slot is arranged at one side far away from the profiling surface, a step surface is formed at the junction of the large slot and the small slot, a flank part of the insert is arrangedin the large slot and is arranged opposite to the step surface, the step surface is used for limiting a lifting position of the side wing part, the head of the insert and the small slot of the steppedslot are in sliding fit, and when the upper mould and the lower mould are closed, the small slot of the stepped slot and the head of the insert define one injection molding cavity between the glass and the nail column. The mould provided by the invention has the advantages that production accuracy requirement of an assembly product on the glass about to being subjected to injection molding can belowered and truck loading positioning accuracy requirement of a glass edging assembly also can be met.

Description

[0001] Technical field: [0002] The invention relates to the technical field of molds for injection molding, in particular to a mold for integral injection molding of glass and nail posts. [0003] Background technique: [0004] The loading positioning of the existing window glass edging assembly mainly relies on the nail cylinder surface or the edging convex table surface (ie loading reference surface) on the back of the window glass product to be attached to the body sheet metal to achieve accurate positioning. In the prior art, insert injection molding is usually used to fix the stud to the window glass, that is, when the glass edging strip is injected, the nail stud is covered in the edging strip of the window glass in the form of an insert. This method has high bonding strength and fast production, and is a commonly used nail post fixing method. [0005] In the existing insert injection molding process, usually the glass and the nail post are respectively fixed in the mo...
