The processing of article shape.Modern society, mold play an irreplaceable role in we live, the big portion of daily necessities
Not mold, such as computer, telephone set, facsimile machine, keyboard, cup plasthetics is detached, in addition as most of in motorcycle
Shell is also to be worked it out with mold, and the effect of mold is irreplaceable, and mold, such as motor are be unable to do without as long as batch production
Front mudguard on vehicle drives the wet mud on ground to splash for preventing rainy day front-wheel from rolling.
As shown in Fig. 1, a kind of front mudguard 9 is installed on the upside of front-wheel in motorcycle, including symmetrically arranged left half
Portion and right side, the both ends of the left side/right side are installation end 9a and gear mud end 9b, the left side and right side
A clamping portion 91 is all had at installation end 9a, the clamping portion 91 includes grab 911 and the position for being located at 9 inside of front mudguard
There are one limit apex angle 9121, and the grab for tool at where the limiting plate 912 of 911 back side of grab, the limiting plate 912
The short slot 9111 of adjustment 911 wall thickness of grab is offered in 911 towards the side of limiting plate 912.
The injection molding difficult point of the front mudguard is at clamping portion, because grab is located at the lower section of limiting plate and is located at front mudguard
Inside, the direction of short slot towards limiting plate, then to be convenient for demoulding at short slot when, then the chipware of molding short slot can not be made towards limit
Position plate direction movement, to which the separation of cover half dynamic model can not be relied on to realize demoulding, it is therefore desirable to one kind have be suitable for molding and
Demould the injection molding of this product.
Utility model content
The purpose of this utility model is to provide a kind of injection molding for manufacturing front mudguard, and specific core pulling knot is arranged
Structure realizes the structure at molding clamping portion, while convenient for demoulding separation.
The above-mentioned technical purpose of the utility model technical scheme is that:One kind is for manufacturing front
The injection molding of mud plate, including fixed half and moving half, the dynamic model include moving platen and are arranged in the ejecting mechanism of moving platen,
It includes being arranged at big convex module to have the big convex module of molding front mudguard inner surface, the ejecting mechanism on the moving platen
Movable push bar and be installed on movable push bar free end and for be molded in front mudguard limit apex angle core pulling apperance, and
There is the molding protrusion for being molded in front mudguard short slot at grab, the moving platen to be located at big punch-pin in the core pulling apperance
The caulking groove disposed for core pulling apperance activity is offered at block and the oblique guide hole worn for movable push bar is communicated with caulking groove, it is described
There is caulking groove the notch appeared for molding protrusion, the core pulling apperance to be respectively provided with mutually with caulking groove backwards to the side of molding protrusion
It is bonded and slides inclined-plane and guiding surface each parallel to oblique guide hole axial direction.
By using above-mentioned technical proposal, the ejecting mechanism of dynamic model includes movable push bar and the pumping fixed with movable push bar
Core model sample, the clamping portion that core pulling apperance is used to be molded in front mudguard, and oblique guide hole and guiding surface are set, consequently facilitating releasing
