Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model will be further described, but embodiment of the present utility model is not limited thereto.
Referring to figs. 1 through Fig. 6, a kind of casing forming mold, comprises moulding box 10, die holder 20, formation die core 30, spreader 40 and sprue bush 50.Described moulding box 10 comprises dynamic model case 11 and cover half case 12.Described die holder 20 comprises dynamic model seat 21 and cover half seat 22.Described dynamic model seat 21 is located at described dynamic model case 11, and described cover half seat 22 is located at described cover half case 12.Described die holder 20 is placed in described moulding box 10, and described formation die core 30 is placed in described die holder 20.The die sinking direction of described formation die core 30 is arranged in the horizontal direction, i.e. direction shown in arrow B in Fig. 5 and Fig. 6.Described sprue bush 50 is arranged at described moulding box 10 along the die sinking direction of described formation die core 30, and is provided with note running channel 51 along the die sinking direction of described formation die core 30.Between described die holder 20 and described formation die core 30, there is molding cavity 60, described die holder 20 is provided with and is communicated with molding cavity 60 and notes running channel 51 and supply metal liquid to enter the runner 23 of molding space 60, described runner 23 is located at the below of described molding cavity 60, the water conservancy diversion direction of described runner 23 pairs of workpiece glues perpendicular to the die sinking direction of described formation die core 30, i.e. direction shown in arrow C in Fig. 5 and Fig. 6.In technical solutions of the utility model, workpiece glue enters from the bottom (i.e. the direction, bottom of Fig. 5 and Fig. 6) of described molding space 60, along with entering of workpiece glue, the liquid level of workpiece glue raises gradually in described molding space 60, until fill whole molding space 60, thus the air can progressively got rid of in molding space 60, and there will not be the situation that in molding space 60, glue is in uneven thickness, thus avoid forming cold line, cold shut or sand hole on workpiece 70 surface.And in prior art solutions, the water conservancy diversion direction of runner 23 pairs of workpiece glues is parallel to the setting in the die sinking direction of described formation die core 30, after workpiece glue enters described molding space 60, described molding space 60 is filled along described formation die core 30 respectively from the both sides of runner 23, because glue is along the irregular flowing of described formation die core 30, glue in molding space 60 can be caused in uneven thickness, and air can not be got rid of in time, cause the generation of bubble, thus form cold line, cold shut or sand hole on workpiece 70 surface.
Preferably, see Fig. 2, described runner 23 is arranged in " Y " shape, and the Liang Ge branch 24 of " Y " shape is the runner of runner 23.The runner 23 of " Y " shape can make workpiece glue from the described molding space 60 of molding space 60 bottom inflow symmetrically and evenly, rational in infrastructure, is conducive to workpiece 70 and forms smooth outer surface, reduce or avoid cold line, cold shut or sand hole.Particularly, in the present embodiment, described Y " shape runner 23 is arranged at the below of described die shoe 22; thus after making metal liquid enter described molding cavity 60; flow directly into the bottom of described molding cavity 60, avoid producing bubble, thus form cold line, cold shut or sand hole on workpiece 70 surface.
Preferably, see Fig. 5 and Fig. 6, one end of described formation die core 30 is placed in described die shoe 22, and described runner 23 is located on described die shoe 22.
Preferably, described dynamic model seat 21 is recessed to form overfall 25 on the side of described molding cavity 60, this overfall 25 is outwards recessed to form overflow launder 26 downwards on dynamic model seat 21, described dynamic model seat 21 is also provided with air discharge duct 27, described air discharge duct 27 one end is communicated with air, the other end is communicated with described overflow launder 26, thus gas is got rid of smoothly.Preferably, be conveniently vented, described runner 23 be located at the below of described dynamic model seat 21, described overfall 25, described overflow launder 26 and described air discharge duct 27 are all located at the top of described dynamic model seat 21, thus are convenient to gas and fully get rid of.Specifically, in the present embodiment, the top of described dynamic model seat 21 is uniformly distributed and is provided with 5 overfalls 25, and each overfall 25 all connects an overflow launder 26 and an air discharge duct 27, thus makes the exhaust structure of molding cavity 60 more rationally compact.But the utility model is to overfall 25, the quantity of overflow launder 26 and air discharge duct 27 does not limit, and it can be selected according to actual needs flexibly.
Described spreader 40 is inserted in described note running channel 51, and is formed between the sidewall of described note running channel 51 and point flow into running channel 52.Described point flows into running channel 52 and is communicated with described runner 23 and described note running channel 51.After workpiece glue enters described note running channel 51, enter described molding cavity 60 through described point of inflow running channel 52 and described runner 23.
Preferably, described point flows into running channel 52 and is more than or equal to 30 millimeters along the length in the die sinking direction of described formation die core 30 and is less than or equal to 90 millimeters, and the end face 41 of outer face 53 to the spreader 40 of the arrival end of described note running channel 51 is more than or equal to 120 millimeters along the length in described formation die core 30 die sinking direction and is less than or equal to 360 millimeters.Thus in process in metal liquid injection moulding cavity 60, all there is at note running channel 51 and point inflow running channel 52 impact of enough buffering metal liquids, make metal liquid to note running channel 51, the impulsive force flowing into running channel 52 and runner 23 is divided greatly to reduce, and then reduce metal liquid to sprue bush 50, spreader 40, the damage of die holder 20 and formation die core 30, thus the service life of casing forming mold of the present utility model is extended greatly, without the need to often changing casing forming mold of the present utility model, the input cost of Die Casting is finally made greatly to reduce, and also there is advantage simple and compact for structure.
Described dynamic model seat 21 and described cover half seat 22 are respectively equipped with the projection 28 and groove 29 that mutually mate.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, its framework form can be flexible and changeable, can subseries product.Just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by submitted to claims.
