Abstract

A special mould structure for injection moulding and covering edges of vehicle and ship glass at least comprises upper and lower moulds, wherein the seal mould face for arranging the edge of glass is embedded with an elastic liner bar. For sealing the die cavity of mould better, another seal mould face of the elastic liner bar opposite the die cavity is best embedded with an elastic liner bar, and the elastic liner bar is made from silicon rubber as best. Compared with prior art, the utility model arranges elastic liner bar between the mould at the seal mould face and glass, to avoid rigid contact between glass and mould, but elastic contact, therefore, in injection made process, the glass is not easy to break, to improve yield rate and support batch production.

Description

A kind of particular manufacturing craft structure of glass of vehicle and ship integral molded plastic bound edge

The utility model relates to a kind of mould structure, particularly a kind of particular manufacturing craft structure of glass of vehicle and ship integral molded plastic bound edge.

Car and boat have specific conditions with glass because of its installation, generally wrap to be installed on the window frame again behind the bound edge of plastic material, existing car and boat with the binding structure of glass are: edge cover strip is the section bar of a prior injection moulding, wherein be provided with and hold glass edge along the caulking groove that inserts, glass edge is behind insertion section bar caulking groove, both are bondd mutually and seal with viscose glues such as butyl rubbers, referring to Fig. 7, the shortcoming of this structure is, after the long-term use, viscose glue between glass and the edge cover strip is easily aging and cause and come unstuck, and finally causes phenomenons such as infiltration.For this reason, we have proposed the patent application that name is called " binding structure that a kind of car and boat are used glass " simultaneously, edge cover strip in this scheme be one with glass edge along as the integral molded plastic spare of inserts, has no the slit between glass and the edge cover strip like this, also need not viscose glue bonding, also just no longer have the problem of coming unstuck, seep water, and this connection mode is more firm, reliably, better tightness; If but have such problem: promptly because glass is more crisp yet directly adopt traditional injection mould to carry out integral molded plastic, and contacting between mould and the glass is the rigidity contact, thereby can directly cause glass breakage, and easily causing phenomenons such as overlap, injection moulding be discontented, yield rate is low.

The purpose of this utility model is with regard to being at the present situation of above-mentioned prior art and a kind of mould structure that carries out the integral molded plastic bound edge with the glass of vehicle and ship edge as inserts that is exclusively used in is provided.

The object of the present invention is achieved like this: the particular manufacturing craft structure of glass of vehicle and ship integral molded plastic bound edge comprises two branch moulds up and down at least, be provided with the elastic material lead-in at the envelope die face place of placing the glass edge edge, make when mold-closing injection not direct contact of mould and glass edge edge.

Be sealed mold die cavity better, preferably also be provided with the elastic material lead-in at another side seal die face place of the relative mold cavity of described elastic material lead-in; Described elastic material lead-in is good to adopt silaatic.

Compared with prior art; the utility model is because of being lined with the elastic material lead-in between mould envelope die face place's mould and glass; make that between glass and the mould no longer be that rigidity contacts; but Elastic Contact, therefore in the Shooting Technique process, glass is difficult for broken; simultaneously; described elastic material lead-in has also played the effect of further sealed mold die cavity, so the yield rate height, is fit to large-scale production.

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 6, be the employing embodiment of circular die 1 up and down, when injection moulding, glass 2 is placed on central authorities, its edge inserts among mould 1 die cavity, patrix 11, counterdie 12 respectively are equipped with a mutual cooresponding silica gel lead-in 13,14 at the envelope die face place of placing glass 2 edges, this second silica gel lead-in 13,14 and glass 2 edge direct contacts, the rigidity position of mould 1 then with glass 2 direct contact not; At the opposite side of mold cavity, patrix 11 or counterdie 12 (being patrix 11 among the accompanying drawing embodiment) also are equipped with a silica gel lead-in 15 at envelope die face place, and to seal die cavity better, 3 are the edge cover strip after the injection mo(u)lding among the figure.

The fixed form of described lead-in 13,14,15 and mould is not limited to the build-in mode, can also adopt other rational fixed forms.

Claims

1. the particular manufacturing craft structure of a glass of vehicle and ship integral molded plastic bound edge is characterized in that comprising at least two branch moulds up and down, is provided with the elastic material lead-in at the envelope die face place of placing the glass edge edge, makes when mold-closing injection not direct contact of mould and glass edge edge.

2. the particular manufacturing craft structure of glass of vehicle and ship integral molded plastic bound edge as claimed in claim 1 is characterized in that also being provided with the elastic material lead-in at another side seal die face place of the relative mold cavity of described elastic material lead-in.

3. the particular manufacturing craft structure of glass of vehicle and ship integral molded plastic bound edge as claimed in claim 1 or 2 is characterized in that described elastic material lead-in is the silaatic material.
