The utility model is owing to have employed above-mentioned technology; the good effect making it compared with prior art to have is: design compound flow passage structure cleverly by increasing on mould; runner is made to be divided into two parts; and two mutual turnings in 90 ° of runner; in casting process, liquid material flows into first flow from cast gate and is flowing to the second runner through turning, plays the effect of buffering step-down; and reduce material temperature, certain protective effect is played to mould and board.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model compound runner aluminium alloy castings mould;
Fig. 2 is the die sinking schematic diagram of the utility model compound runner aluminium alloy castings mould.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
Refer to Fig. 1, shown in Fig. 2, a kind of compound runner of the utility model aluminium alloy castings mould, be applied to horizontal hot chamber machine, comprise template and injection device, injection device is arranged in template.Injection device comprises the cast gate be communicated with successively, first flow 6, the second runner 8, spreader 9 and die cavity, and wherein runner designs for composite flow channel.Template comprises solid plate 1, intermediate plate 2, moving platen 3 and thimble, solid plate 1, intermediate plate 2 and moving platen 3 are flexibly connected successively, thimble is used for the product after shaping to eject from die cavity, and one end of first flow 6 is arranged on solid plate 1, specifically above illustrated first flow 6, is provided with depressed part 7.
At cast gate, place is also provided with ejecting structure, for cast gate and first flow 6 are ejected solid plate 1.In preferred embodiment of the present utility model, ejecting structure comprises piston channel and piston 5, the removable discrepancy piston channel of piston 5, it is outer and be positioned on the mobile route of piston 5 that first flow 6 is located at piston channel, and first flow 6 and the mutual turning in 90 ° of the second runner 8.
Continue referring to shown in Fig. 1 and Fig. 2, be connected by limiting plate 11 between solid plate 1 with intermediate plate 2, be connected between limiting plate 11 with solid plate 1 with steady pin, fix between limiting plate 11 and intermediate plate 2 with moving pin, moving pin can move on limiting plate 11.Limiting plate 11 controls being separated of intermediate plate 2 and moving platen 3.
In further embodiment of the present utility model, in casting process, liquid aluminium enters first flow 6 from cast gate, behind the turning of 90 °, flow to the second runner 8 again, flows in die cavity cast out product through spreader 9.The design of this compound runner solves product need in the problem of middle pan feeding, and the runner turning designing 90 ° then avoids the position problems because of cast gate, meets the needs that mould need offset downward simultaneously.And the design liquid towards material of this compound runner plays the effect of cooling and compensator or trimmer pressure, and product because material temperature is too high, water wave can not occur, bubble, the bad phenomenon such as carbon distribution.The effect of compensator or trimmer pressure then reduces the pressure of board to mould, also reduces the pressure of mould to board simultaneously, plays certain protective effect to mould and board, add the mold use life-span.
In further embodiment of the present utility model, continue referring to shown in Fig. 1 and Fig. 2, in solid plate 1 and moving platen 3 separation process, first flow 6 is blocked by the depressed part 7 above runner, first flow 6 and the second runner 8 is broken by force under the effect of mould opening force, compound runner is separated, and when solid plate 1 and moving platen 3 are separated to certain distance, piston 5 ejects cast gate with first flow 6 and is separated with solid plate 1.
In die sinking process, intermediate plate 2 is separated with solid plate 1, and moving pin is followed intermediate plate 2 and moved together, arrive certain distance moving pin and arrive limiting plate 11 edge, limiting plate 11 blocks moving pin, then intermediate plate 2 is not moving, and at this moment moving platen 3 continues mobile and is separated with intermediate plate 2.
In further embodiment of the present utility model, after intermediate plate 2 is separated with moving platen 3, product is followed moving platen 3 and is moved together, arrives certain distance moving platen 3 and stops mobile, ejecting product under the thimble effect at mould pin 4 place; Intermediate plate 2 be designed with the pan feeding and depanning that are beneficial to product, solve some because of pan feeding difficulty, the product of Design of Dies complexity, and being designed with to be beneficial to and ensureing the profile of cast article and size of intermediate plate 2.
The foregoing is only the utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain is limited; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilization the utility model descriptions and diagramatic content and apparent change obtain in protection domain of the present utility model.
