Embodiment 1

The utility model discloses a kind of plastic mould of fast demoulding, comprising: cover half 1 and dynamic model 2, fixed 1 direction The side of the dynamic model 2 has dynamic mould core 4 towards the side of the cover half 1 with model cavity 3, the dynamic model 2 is determined, wherein Convex block 6, band on the both sides that the dynamic model 2 and the cover half 1 match are had on the both sides that the cover half 1 and dynamic model 2 match Fluted 7, the cover half 1 and dynamic model 2 are realized by the cooperation of the convex block 6 and groove 7 and connect closure, to make the dynamic model Type core 4 and it is described determine model cavity 3 and match, and formed for accommodating the mold cavity 5 for melting sizing material.

The middle part of the dynamic mould core 4 is equipped with the glue injection channel 8 through the dynamic model 1, and the glue injection channel is loudspeaker Shape structure, small-caliber end towards the top surface of the dynamic model, take a picture the lower edge of the dynamic model core 4 by large diameter end.The knot 8 one side of glue injection channel of structure is conducive to melting sizing material and is uniformly distributed in mold cavity 5, on the other hand, after the completion of injecting glue It shrinks and solidifies convenient for glue.

Described to determine to be built-in with cooling pipe 9 in model cavity 3 and the dynamic mould core 4, which is snakelike metal Pipe is realized and is quickly cooled down to the moulding 11 in mold cavity, conveniently for connecting extraneous cooling water or low temperature compressed air Demoulding.Specifically, the cooling pipe 9 determined in model cavity 3 is the coiled pipe that single layer is placed, the cooling in the cooling pipe Medium flow direction is in the same direction with the length direction of the mold cavity, and the width of the cooling pipe is more than or equal to the mold cavity Width, and the inlet end of cooling pipe and water outlet end stretch out the plastic mould.

Cooling pipe 9 in the dynamic mould core 4 is 2 layers or more the coiled pipes placed, wherein close to 1 side of cover half Coiled pipe is distributed in the dynamic mould core 4 and is located on the upper limb of the mold cavity 5, and the cooling medium flow direction in cooling pipe In the same direction with the length direction of the mold cavity, the width of the cooling pipe is more than or equal to the width of the mold cavity, and The inlet end and water outlet end of cooling pipe stretch out the plastic mould.The cooling water pipe of other each layers is bottom-up (i.e. From the direction of the lateral dynamic model side of cover half one) two sides of the glue injection channel 8 are distributed in, for will be residual in the glue injection channel Remaining sizing material is cooling, reduces the difficulty of Jiao Kou demoulding.

It is equipped in the cover half 1 and jacks up component 10, the jack-up component 10 includes Ejector Retainer Plate 101, thimble mounting plate 102 and thimble 103, wherein the Ejector Retainer Plate 101 is fixed on the cover half 1, and the thimble mounting plate 102 is fixed on institute It states on Ejector Retainer Plate 101, the thimble 103 is vertically installed on the thimble mounting plate 102.Specifically, the thimble 103 has Three rows, top are located at the two sides and middle part for determining 3 lower surface of model cavity.For by the bottom surface of moulding 11 and lower die Uniformly separate.

In addition, the bottom end quadrangle of the lower die has support column 12, the top two sides of the upper mold have power device 13.

The working principle of the plastic mould of the fast demoulding of the utility model are as follows: after fixed half and moving half molding, pass through note Glue channel injects melting sizing material into mold cavity and is passed through the cold sky of cooling water or compression into cooling pipe after filling Gas makes the upper and lower faces of moulding while cooling, while cools down the remaining sizing material in glue injection channel together, then passes through top Component is played by the lower surface of moulding and determines model cavity disengaging, is pulled upwardly dynamic model by power device, while glue injection equipment (usually injecting glue screw rod) withstands glue injection channel, so that the sizing material in glue injection channel is connected to moulding and is detached from together with dynamic mould core, To realize the demoulding of moulding.

The plastic mould of the fast demoulding of the utility model, by logical in the upper surface, lower surface and injecting glue of mold cavity The two sides in road are respectively provided with cooling device, the remaining sizing material in entire moulding and gum-injecting port are cooled down simultaneously, to mention The high demoulding efficiency of entire moulding, the demoulding difficulty being especially reduction of at gum-injecting port；Using the plastic cement of the utility model The stripping rate of mold, moulding is fast, and demolding performace is reliable, high production efficiency, and practicability is stronger.
