Brief description of the drawings
The above and other feature of the present utility model, character and advantage are by by becoming more obvious below in conjunction with the description of drawings and Examples, wherein:
Fig. 1 is the front view of the spreader for knuckle counter-pressure casting mould of an embodiment of the utility model.
Fig. 2 is the top view of spreader in Fig. 1.
Fig. 3 is the front view of the dynamic model of knuckle counter-pressure casting mould in comparative example of the utility model.
Fig. 4 is the front view of the dynamic model of the knuckle counter-pressure casting mould of an embodiment of the utility model.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to the utility model intension in the situation that, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
Fig. 1, Fig. 2 have shown separately the shape of spreader, and Fig. 4 shows the state that spreader is attached to counter-pressure casting mould.It should be noted that these and follow-up other accompanying drawing are all only as example, it is not to draw according to the condition of equal proportion, and should be using this as the protection domain of the utility model actual requirement is construed as limiting.
Counter-pressure casting mould comprises fixed half and moving half, cover half is fixed on cover half installing plate, operated by rotary motion has sprue to be connected with pressure chamber, dynamic model is fixed on dynamic model installing plate, and servo-actuated mold mounting plate is while making folding mould or mobile matched moulds, closed formation die cavity and casting system, liquid metals is under high pressure full of die cavity; When die sinking, dynamic model separates with cover half, by means of the ejecting mechanism being located on dynamic model, foundry goods is released.Dynamic model is realized accurate movement by leading accurate part, leads accurate part and comprises guide pillar, guide pin bushing etc.Foundry goods is pushed out by ejecting mechanism, and ejecting mechanism comprises push rod or thimble, release link, ejector pin retaining plate, push pedal, push pedal guide pillar, ejector guide pillar etc.Counter-pressure casting mould also disposes overflowing system, cooling system, side core-drawing mechanism etc. in addition.In embodiment of the present utility model, be mainly that the spreader on dynamic model is improved, therefore the structure of other parts to counter-pressure casting mould, operating principle have not just launched in detail.
As shown in Figure 1, for the corresponding free bearing of spreader 1 hole site of knuckle counter-pressure casting mould, comprise cone 12 and bar portion 11.Thereby the bottom of cone 12 is formed as the step plane of energy axial location spreader 1 than the bottom surface 121 of bar portion's 11 thick cones 12, the bottom of cone 12 is formed with multiple bolts hole 233, so that by bolted on the dynamic model 2A of die casting, the base diameter of cone 12 is identical with free bearing bore dia, described herein identical not completely equal, comprise approximate situation.In addition, the length of cone 12 is enough to make the dead eye position of knuckle blank to be shaped to through hole.
As shown in Figure 4, it is upper that dynamic model 2A is located and be fixed on to spreader 1, the effect of spreader 1 in mould: play shunting, guiding, reduce and impact, can make metal liquid Quick uniform fill, quick cooling cast rising head.In addition, spreader 1 is owing to having occupied the space of die cavity, and this space can not filled by metal liquid, therefore can form the dead eye of knuckle.Spreader 1, by the bottom surface 121 of cone 12 and the lower plane laminating of dynamic model 2A, is realized the object to spreader 1 axial location.The body of rod 11 of spreader 1 comprises thicker Part I 112 and thinner Part II 111, and thicker Part I 112 accurately coordinates with the hole 21 of dynamic model 2A, realizes the object to spreader 1 axial location.Part II 111 passes from dynamic model 2A.As shown in Figure 1, Part I 112 and cone 12 adjacency, Part II 111 and Part I 112 adjacency.As shown in Figure 4, spreader 1 also has cooling channels 13, and cooling channels 13 runs through whole bar portion 11, also extends to cone 12 inside.
As shown in Figure 2, three bolts hole 122 that form on the bottom surface 121 of cone 12 are uniformly distributed at circumferencial direction, and as shown in Figure 4, bolt 22 screws in and is connected with bolt hole 122 from the upper end of mould 2A, so just spreader 1 is fastened on dynamic model 2A.
As shown in Figure 3, in a comparative example of the present utility model, on dynamic model 2, be equipped with spreader 1A, the vertex of a cone tip size of spreader 1A is less, also shorter, press-fiting step by bar portion tail end locates, spreader 1A is the dead eye of corresponding knuckle also, but the dead eye of the knuckle blank of moulding is blind hole, and dead eye aperture is more much larger than this blind hole aperture, this will cause the many procedures of follow-up machine processing, and allowance is also larger.
Although the utility model with preferred embodiment openly as above, it is not for limiting the utility model, and any those skilled in the art, not departing from spirit and scope of the present utility model, can make possible variation and amendment.Therefore, every content that does not depart from technical solutions of the utility model, any amendment, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, within all falling into the protection domain that the utility model claim defines.
