As it is shown in figure 1, this utility model provides a kind of die casting, including substrate 5, male template 1, male model thermal insulation board 2, male die core 9, mother module core 10, master mold thermal insulation board 7 and caster 6.Substrate 5 is arranged on the lower section of male template 1 and is fixedly installed on the ground.Male template 1 and caster 6 are respectively provided with male die cavity and female die cavity, male model thermal insulation board 2 and master mold thermal insulation board 7 and are respectively fixedly disposed in male die cavity and female die cavity.Male die core 9 and mother module core 10 are separately positioned in male die cavity and female die cavity, and male die core 9 and mother module core 10 fasten the die cavity 8 forming product mutually, and the liquid injected in die cavity 8 forms product after die casting cooling.It is arranged on the male model thermal insulation board 2 in mould and master mold thermal insulation board 7 makes the good heat-insulation effect in forming process of the product in die cavity 8, can effectively prevent thin-walled die-cast product from the defect such as cold junction stricture of vagina, filling insatiable hunger occurring in forming process, improve product yield, and the loss of energy can be reduced.Wherein, male model thermal insulation board 2 and master mold thermal insulation board 7 are made up of heat-barrier material, for instance bakelite.
As in figure 2 it is shown, be provided with at least one boss 3 in male die cavity.As shown in Figure 4 and Figure 5, male model thermal insulation board 2 is provided with through hole 4 for boss 3 traverse corresponding to each boss 3.In conjunction with Fig. 1, being also equipped with at least one boss 3 in female die cavity, master mold thermal insulation board 7 is provided with through hole 4 for boss 3 traverse corresponding to each boss 3.Therefore, when die casting, boss 3 supports the pressure receiving male die core 9 and mother module core 10, serves the effect of protection male model thermal insulation board 2 and master mold thermal insulation board 7, makes male model thermal insulation board 2 and master mold thermal insulation board 7 be unlikely to deform.In the present embodiment, the boss 3 in male die cavity is mutually corresponding with the boss 3 in female die cavity, thus the pressure distribution that during die casting, boss 3 bears is evenly.
In the present embodiment, the cross section of boss 3 and the through hole 4 corresponding with boss 3 is set to square or circular.The boss 3 of notebook class mould is traditionally arranged to be 9, and Fig. 3 illustrates the arrangement position of corresponding through hole 4.
As it is shown in figure 1, parallel in the plate face that the plate face of male model thermal insulation board 2 and master mold thermal insulation board 7 is set to substrate 5, thus during die-cast product, being more uniformly stressed of mould.Male model thermal insulation board 2 is arranged on the inner bottom surface of male die cavity, and master mold thermal insulation board 7 is arranged on the inner top surface of female die cavity.If the product of molding has back-off, then mould needs slide block molding, when the medial surface of male die cavity and female die cavity has larger space, owing to air is the non-conductor of heat, sidewall in male die cavity and in female die cavity can be not provided with thermal insulation board, certainly arranges thermal insulation board in the medial wall of male die cavity and female die cavity and can strengthen effect of heat insulation further.Thermal insulation board can be screwed in male template 1 or caster 6.
Needing in mould to arrange ejecting structure, during such as thimble or taper pin, if ejecting structure needs to pass thermal insulation board (male model thermal insulation board 2 and/or master mold thermal insulation board 7), thermal insulation board should offer corresponding through hole.
When formed product in die cavity, owing to the thickness at each position of product is different, the cool time required for each position is different.When full liquid is filled at relatively thin position, when thicker position is not filled by full, if it is heat insulation that the product at relatively thin position do not carry out partial insulation, easily there is cold junction stricture of vagina or filling insatiable hunger in product, causes product not easily die cast.There is the defect of cold junction stricture of vagina, filling insatiable hunger etc. in the effectively product solved in thin-wall die casting molding that arranges of thermal insulation board, improves formed product rate.
In order to be further ensured that effect of heat insulation, die casting of the present utility model also includes heating rod, and the heating part of multiple heating rods is by fitting with male die core 9 and mother module core 10, so that die cavity 8 to be heated, and then the product to be formed in die cavity 8 is incubated.Heating rod can be Si-Mo rod or siliconit.By arranging heating rod, it is possible to achieve the local of die cavity 8 is heated.The high-temperature heating of local, it is possible to the problem effectively solving product local shrinkage depression.
