Abstract
The utility model discloses a plastic mould hot runner device, which comprises an upper molding mould, a lower molding mould and a nozzle, wherein a sprue bush is arranged in the lower molding mould, a flow channel is arranged in the sprue bush, the upper end of the flow channel is communicated with the nozzle, the lower end is provided with a point sprue, and the point sprue is communicated with a mould molding cavity. The plastic mould hot runner device has simple structure and low cost, the outer portion of the sprue bush is provided with an insulating layer structure, thereby removing a traditional heating device, pouring and being capable of excellently retaining the temperature of hot melt plastics in the flow channel at the same time, delaying the decline curvature of temperature, and excellently guaranteeing the surface quality of plastic products.
Description
Technical field
The utility model relates to produces plastic products class device, a kind of specifically plastic mould hot flow path device that is used to produce equipment plastic casings help moulding such as printer, duplicator.
Background technology
PET is commonly called as polyester resin, and the plastic products made from PET are subjected to using widely because of having big, nontoxic, the lightweight advantage of intensity, such as the shell of printer, duplicator etc.Mainly take injection moulding processing at present, injection mo(u)lding is the plastic material with the hot melt state, by injection moulding machine it is injected sealing moulding cavity in the mould at high speed, after the plastic material solidifies cooling, the plastic product of curing molding can be ejected, to obtain the mode of predetermined prod.Therefore the quality of mold hot flow and device thereof just becomes the key factor of producing plastic product quality quality, and mold hot flow complex structure, the production efficient of prior art surface quality low, plastic product is more coarse etc.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved in the utility model is, provide a kind of simple in structure, with low cost, improve the surface quality of plastic product and the plastic mould hot flow path device of production efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of plastic mould hot flow path device, comprise mould, compacted under mould and nozzle, in the described upper and lower mould sprue bush is set, runner is set in the sprue bush, the runner upper end communicates with nozzle, set-point, lower end cast gate, and described some cast gate communicates with the mould molding chamber.
Above-mentioned plastic mould hot flow path device is provided with heat-insulation layer between described sprue bush and the upper and lower mould.
The advantage of the utility model plastic mould hot flow path device is: this apparatus structure is simple, with low cost, heat insulation layer structure is set outside sprue bush, removed traditional heater, the temperature that in cast, can well keep hot melting plastic in the runner, delay temperature decline curvature, very high assurance the surface quality of plastic product.
Description of drawings
Fig. 1 is the utility model plastic mould hot flow path apparatus structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details;
As described in Figure 1, structural representation for a kind of plastic mould hot flow path of the utility model device, it comprises mould 1, compacted under mould 2 and nozzle 3, last mould 1 match with compacted under mould 2 section mould molding chamber 7 is set, described going up in mould 1 and the compacted under mould 2 is provided with sprue bush 4, and runner 5 is set in the sprue bush 4, and runner 5 upper ends communicate with nozzle 3, set-point, lower end cast gate 6, described some cast gate 6 communicates with mould molding chamber 7.
Described sprue bush 4 and upper and lower mould are provided with heat-insulation layer 8 between (1,2), and this heat-insulation layer 8 is an insulating air layer, and the thickness of insulating air layer is 1: 4 with the ratio of the average diameter of runner 5, and wherein the upper end diameter of runner 5 is greater than its lower end diameter.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
