It further includes under being set between lower die heating component and lower impressions as a further improvement of the utility model,
Mould cooling tube, the lower die cooling tube both ends extend to outside lower impressions.
The beneficial effects of the utility model are：
(1) by the way that hollow plate is arranged and fire-bar is arranged in hollow plate, after upper layer and lower layer molding is nearly completed, injection
The material liquid of middle layer, while slightly melting by fire-bar the surface of upper layer and lower layer middle, make middle layer and upper layer and lower layer
It connects even closer, simultaneously because fire-bar is in middle section, does not interfere with the appearance of product；
(2) by the way that heating tube and cooling tube are arranged between upper mold and lower die, and heating tube and cooling tube intersection are set
It sets, efficiently and rapidly the temperature of raw material can be controlled, ensure temperature uniformly and temperature control is accurate, further increase
Product quality.
Above-mentioned is the general introduction of utility model technical solution, below in conjunction with attached drawing and specific implementation mode, to the utility model
It is described further.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure, lower die 1, lower impressions 11, upper impression 21, hollow plate 3, middle injection hole 4, exits mouth 5, fire-bar at upper mold 2
31, upper injection hole 22, lower injection hole 12, upper mold heating tube 6, lower die heating tube 7, upper mold cooling tube 8, lower die cooling tube 9.
Specific implementation mode
Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose is taken, below in conjunction with
Specific embodiment of the present utility model is described in detail in attached drawing and preferred embodiment.
Fig. 1 is please referred to, the present embodiment provides a kind of three color injection molds, including the upper mold that lower die 1 and lower die 1 match
2, lower impressions 11 are provided in the lower die 1, and the upper impression 21 to match with lower impressions 11 is provided in the upper mold 2, it is described
A hollow plate 3 is detachably provided in lower impressions 11,11 one end of the lower impressions is provided with the middle note to match with hollow plate 3
Mouth 4 is moulded, the other end is provided with exits mouth 5 with what hollow plate 3 matched, is set respectively in 3 inside upper and lower surface of the hollow plate
It is equipped with fire-bar 31.By the way that hollow plate 3 is arranged and fire-bar 31 is arranged in hollow plate 3, it is nearly completed in upper layer and lower layer molding
Afterwards, inject the material liquid of middle layer, while slightly melting the surface of upper layer and lower layer middle by fire-bar 31, make middle layer with
Upper layer and lower layer connection is even closer, simultaneously because fire-bar 31 is in middle section, does not interfere with the appearance of product.Exit mouth 5
