Abstract
The utility model discloses a mould runner for making polyester bottle blank, comprising a ball part, a spraying nozzle, a hot flow passage plate, an equal height spacer block, and a fixed mould plate, wherein, the ball part is connected to the injection direction of a mould cavity of a mould, and the feeding and the discharging ports of the spraying nozzle are respectively opposite to the ports of the hot flow passage plate and the ball part; the feeding port of the hot flow passage plate is connected with the port of an injection moulding machine. The utility model is characterized in that the fixed mould plate is provided with a cylinder which is provided with an air port and a cover, and a piston which is provided with a ring and a rod is arranged inside the cylinder; the rod is glidingly fitted with the fixed mould plate, etc. and is penetrated to the discharging port of the spraying nozzle. The utility model has the advantage that the bottle blank has no surplus materials and favorable transparency, the mould has long service life, and excess aldehyde is not kept, etc.
Description
The utility model belongs to a kind of parts of plastic product forming mould, particularly makes the mould gate of polyester bottle base.
The mould gate of the making polyester bottle base that generally uses at present is down gate, this gate form can make raw material inject mold cavity forming with low heating-up temperature, low injection pressure and higher injection speed, the polyester bottle base transparency of Zhi Zuoing is good and the acetaldehyde residual quantity is low like this, but all link on the shaped article of down gate the cast gate clout is arranged, need cut off clout by hand after the demoulding, waste raw material like this, increased workload and influenced operating efficiency.In order to solve the problem of cast gate clout, the someone has adopted the way of some cast gate.Because it is very little to put cast gate, so need to improve the heating-up temperature of raw material and strengthen injection pressure, can have influence on the transparency of polyester bottle base like this, die life is also shorter, the residual acetaldehyde that excess is arranged of bottle base more seriously, acetaldehyde can be dissolved in the Sheng liquid of shaped bottle and endanger health of human body.
The purpose of this utility model provides a kind of mould gate of improved making polyester bottle base, can overcome the defective of prior art.
The utility model is achieved in that a kind of mould gate of making the polyester bottle base, comprise the bulb that is fixed on the die matrix, nozzle, hot runner manifold, contour cushion block, solid plate, wherein the bulb is used for being connected with the injection side of mold cavity, the discharging opening of nozzle is over against the charging aperture in bulb, the charging aperture of nozzle is over against the discharging opening of hot runner manifold, the charging aperture of hot runner manifold is used for being connected with the discharging opening of injection machine, it is characterized in that a cylinder is arranged in the solid plate, cylinder has air inlet/outlet and cylinder head, piston is arranged in the cylinder, piston ring and piston rod are arranged, piston rod and solid plate on the piston, contour cushion block, hot runner manifold is slidingly matched and is set in the nozzle to the nozzle discharging opening.
Such scheme is owing to be provided with cylinder and piston in the solid plate, piston rod is set in the nozzle to the nozzle discharging opening, when the injection machine charging finishes, cylinder can control piston the piston masthead to the nozzle discharging opening, clout in the nozzle is refluxed and the outer bottle base of disengaging nozzle discharging opening, and the bottle base that goes out mold forming so just no longer links clout.Because this method is to adopt the method for machinery to solve the clout problem, does not need to improve the heating-up temperature and the injection pressure of raw material, so can not reduce the transparency and the die life of bottle base, also can not make the residual excessive acetaldehyde of bottle base.
Below in conjunction with accompanying drawing the utility model is done to describe more specifically.
Fig. 1 is the vertical profile schematic diagram of a kind of scheme of the utility model.
With reference to Fig. 1, this mould gate, comprise and be connected in series the bulb 1 that is fixed on die matrix successively, nozzle 2, hot runner manifold 3, contour cushion block 4, solid plate 5, wherein bulb 1 is used for being connected with mold cavity injection side, the discharging opening 6 of nozzle 2 is 1 charging aperture 7 over against the bulb, the charging aperture 8 of nozzle 2 is over against the discharging opening 9 of hot runner manifold 5, the charging aperture 10 of hot runner manifold 3 is used for being connected with the discharging opening of injection machine, feature is that a cylinder 11 is arranged in the solid plate 5, air inlet/outlet 12 is arranged on the cylinder 11,13 and cylinder head 14, piston 15 is arranged in the cylinder 11, piston ring 16 and piston rod 17 are arranged on the piston 15, piston rod 17 respectively with solid plate 5, contour cushion block 4, hot runner manifold 3 is slidingly matched and is set in the nozzle 2 to nozzle discharging opening 6.In addition, piston 15 and piston rod 17 tighten together by pad 18 and nut 19; The part junction surface also has pad 20 and 21.
During use, the foreign side in bulb 1 is connected with mold cavity injection side, and the charging aperture 10 of hot runner manifold 3 is connected with the injection machine discharging opening.During injection moulding, air inlet/outlet 12 air inlets, mouth 13 is given vent to anger, piston 15 moves to right, piston rod 17 moves to right and exposes the discharging opening 6 of nozzle 2 and the discharging opening 9 of hot runner manifold 3, at this moment injection machine injectable raw material is successively from the charging aperture 10 of hot runner manifold 3, discharging opening 9, the charging aperture 8 of nozzle 2, discharging opening 6, the charging aperture 7 in bulb 1, enter mold cavity, when injection moulding finishes, air inlet/outlet 13 air inlets, mouth 12 is given vent to anger, and piston 15 moves to left, and piston rod 17 left lateral are to its terminal discharging opening 6 that arrives nozzle 2, the afterbody clout of nozzle 2 can be subjected to squeeze backflow and no longer link to each other with the bottle base of bulb 1 foreign side like this, and the bottle base that die sinking is taken out just no longer links clout.
