Abstract
The invention provides a backlash compensation structure of a vehicle glass injection molding die. Which comprises a fixed die and a moving die; the fixed die is arranged on the moving die; the fixed die and moving die are matched; the moving die is arranged on a fixing plate; glass is arranged between the fixed die and the moving die; the moving die consists of a floating die core and a moving die body; the floating die core is arranged in a cavity of the moving die body; the floating die core is provided with at least three penetrating holes from top to bottom; adjusting screws penetrate through the holes and bottoms of the adjusting screws are screwed with the fixing plate; springs sleeve the adjusting screws; the adjusting screws are rotated to drive the floating die core to move up and down to adjust the position of glass. The backlash compensation structure has the advantages that by adopting the technical solution, the problems of easiness in breaking of the glass and surplus trimmings generated at the outer surfaces of parts of a common glass injection molding edge covering die in an injection molding edge covering process are avoided, damage to the die caused by glass breaking is reduced and increased maintenance cost is reduced; the generation of trimmings also requires a manual maintenance procedure and cost.
Description
Technical field
The present invention relates to a kind of automobile glass encapsulation mould, especially a kind of vehicle glass injection mold backlash compensation structure.
Background technology
Along with the fast development of auto manufacturing, auto manufacturing technology is more and more advanced, companion's and the price of parts be also more and more lower trend. The pressure that huge manufacturing cost rises has born in enterprise. Manufacturing enterprise only has the technology energy level by improving self, the reduction manufacturing cost of constantly bringing forth new ideas, pick up from product, mould development source, the design concept of uses advanced, advanced technology, reach the qualification rate that reduces cost of goods manufactured, improves product, thereby make the product of manufacturing no matter in quality or price, have more competitiveness, on cost, realize doulbe-sides' victory.
General glass injection-molding edge principle of mould design is to put into the die cavity being formed by dynamic model, cover half using glass as inserts, and then injection mo(u)lding after mould matched moulds is opened mould after cooling and taken out workpiece, has completed bound edge process. But because thickness of glass is to exist to change, its deviation is generally δ ± 0.2mm left and right. And the spatial joint clearance design of holding glass in general mould manufactures and designs by glass δ+0.2mm, all can put into die cavity with the glass that meets different-thickness. But produce thus a problem, once mould complete after its die cavity space be constant, if cause crushing glass after the too thick mould of glass matched moulds because die cavity space is too little. Will produce the gap of 0.4mm if thickness of glass is δ-0.2mm, therefore in injection moulding process, plastics colloid will overflow and produce overlap from gap, has affected the presentation quality of product, and needs increase manually to repair together the operation of removing, and has increased cost.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of vehicle glass injection mold backlash compensation structure, comprise fixed half and moving half, cover half is placed on dynamic model, both mate mutually, dynamic model is placed on fixed head, glass is placed between fixed half and moving half, described dynamic model is made up of float mould core and dynamic model body, float mould core is placed in dynamic model body hole, float mould core has three through holes from top to bottom at least, in hole, pass adjusting screw(rod), adjusting screw(rod) bottom is spirally connected with fixed head, on adjusting screw(rod), cover has spring, turn adjusting screw(rod), drive on float mould core, lower movement, adjust glass position.
Adjustment pad is also housed on described spring.
The contact-making surface of float mould core top and glass is greater than 25mm.
The invention has the advantages that: adopted and after technique scheme, avoided general glass injection-molding edge the mould easy fragmentation of glass and part outer surface in injection-molding edge process to produce unnecessary overlap problem, reduce the mould damage causing because of glass breaking, and the maintenance cost increasing; The generation of overlap also needs to increase by one manual repair's operation and expense.

Detailed description of the invention
As shown in Figure 1, the invention provides a kind of vehicle glass injection mold backlash compensation structure, comprise cover half 1 and dynamic model, cover half 1 is placed on dynamic model, both mate mutually, dynamic model is placed on fixed head 9, glass 3 is placed between cover half 1 and dynamic model, described dynamic model is made up of float mould core 5 and dynamic model body 8, float mould core 5 is placed in dynamic model body 8 holes, float mould core 5 has three through holes from top to bottom at least, in hole, pass adjusting screw(rod) 4, adjusting screw(rod) 4 bottoms and fixed head 9 are spirally connected, on adjusting screw(rod) 4, cover has spring 7, turn adjusting screw(rod) 4, drive on float mould core 5, lower movement, adjust glass 3 positions.
Further, on spring, be also equipped with and adjust pad 6.
The contact-making surface of float mould core 5 tops and glass 3 is greater than 25mm.
