Abstract
The utility model discloses a low speed die casting machine. A host machine is composed of an upright post, an upper machine frame, a lower machine frame, and a movable beam. The host machine is composed of a power source and a casting ejector mechanism, and the power source is composed of a matched die and a casting hydraulic cylinder. A casting mechanism is composed of a stepped hole arranged on the lower machine frame, a charging basket, asbestos arranged on the top of an injection plunger; the big end of the charging basket is fixed, and the injection plunger is arranged on the small end of the charging basket. When the low speed die casting machine is used, a casting die is fixed on a die holder. The smelted molten metal is poured into a hot top, die plates are tightly locked by the start-up of the power source, the injection plunger is moved up to compress the hot top, the molten metal can be slowly filled into a mould cavity, and the solidification of the molten metal under a high pressure can be realized. The runner and feeder head of the low speed die casting machine are integrated together. The utility model has the advantages of high utilization ratio of metal, high yield of products, no air hole, low energy consumption, low cost, and less investment.
Description
The utility model relates to a kind of metal die-casting machine, the low speed die casting machine.
The general many employings of existing factory are upright, horizontal plunger die casting machine is produced die casting, and on the one hand because of the die casting machine costliness, general small enterprise holds and dares not accept, the subcutaneous pinhole of foundry goods ubiquity that other aspect die casting machine is extruded, general character defectives such as shrinkage porosite.
The purpose of this utility model is to provide a kind of low speed die casting machine, and the vertical hydraulic press of promptly reequiping little tonnage substitutes the above die casting machine of twice tonnage and uses, and can eliminate the pore shrinkage porosite in the foundry goods.
The utility model is achieved in that by column, upper and lower frame, walking beam etc. forms main frame, and the power source and the foundry goods ejecting mechanism that are fixed with matched moulds, potting syrup cylinder pressure formation on it are formed, the also fixing mechanism of pouring into a mould on the main frame.
Fig. 1. structural representation of the present utility model.
Fig. 2. the utility model course of work schematic diagram.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Matched moulds with and cast be screwed respectively in upper and lower frame (2), (9) with hydraulic cylinder (1), (10) and go up the formation power source.
Two columns (3) pass upper spider (2), walking beam (5), lower bearing bracket (9) respectively and are screwed formation host machine part in aggregates.
The upper and lower surface of walking beam (5) is screwed piston (20) respectively, ejects frame (4), uniform 2～4 pilot pins (19) are passed in the centre, on two cantilevers pulley is housed, following extension weight (8), and other end lanyard is on lower bolster (15) edge.
Be fixed with the pressing plate (18) of knock-pin (17) and eject frame (4) inwall cunning and join, cope match-plate pattern (16) is screwed and is ejecting on the frame (4).Cope match-plate pattern (16), knock-pin (17), pressing plate (18), pilot pin (19), eject frame (4) and constitute the foundry goods ejecting mechanism.
Dies holder (14) is screwed on lower bearing bracket (9), and 4 guide fingers (7) are fixed on the edge of dies holder (14).
Shoulder hole is arranged in the middle of the lower bearing bracket (9), the charging basket (13) of stationary cylinder shape in the big stomidium, injection piston (11) passes little stomidium, piston (11) two ends are slided with charging basket (13) inwall, hydraulic cylinder (10) respectively and are joined, in the charging basket (13), the top of piston (11) is placed with the hot top of being made by asbestos (12) and constitutes cast mechanism.
During use, mould is fixed on upper and lower template (16), (15), and melted molten metal poured in the hot top (12), start closing liquid cylinder pressure (1), lock upper and lower template (16), (15) when being moved down into terminal point along column (3) when piston (20) drives walking beam (5) under hydraulic-driven.
At this moment lower bolster (15) seals the sprue gate of charging basket (13) just, start again potting syrup cylinder pressure (10) make injection piston (11) move up the compression hot top (12), thereby molten metal is full of lentamente keeps high pressure behind the die cavity continuously, (adjustable in pressure joint) forces molten metal fully during solidification and crystallization, potting syrup cylinder pressure (10) release injection ram (11) to be resetted under this high pressure.Starting closing liquid cylinder pressure (1) makes closing piston (20) be with a complete set of compression mod and foundry goods to rise.The mould that lower bolster (15) is above together rises along guide finger (7), lower bolster (15) is separated with charging basket (13) finish the first order demoulding.When lower bolster (15) rises to guide finger (7) when upper end, stopped by nut (6) and can not continue to rise, but be subjected to weight (8) pulling force also can not fall to finishing the second level demoulding.When walking beam (5) continues to rise, after pilot pin on it (19) is run into upper spider (2), pilot pin (19) moves down the pressing plate (18) that promotes to be fixed with knock-pin (17) and moves down, then foundry goods is ejected bar (17) and ejects from cope match-plate pattern (16) and finish the third level demoulding, promptly finishes the function of die casting machine.
But change the foundry goods of different mould die casting different wall and size as required.
The utility model is compared with prior art: because just replacing conventional die casting machine use more than the twice tonnage as long as increase the casting mechanism counterweight at the double-cylinder hydraulic machine, equipment investment is few. Dead head unites two into one, and using rate of metal can reach more than 90%. And pouring temperature can be hanged down about 100 ℃ than routine, consume energy low, cost is low. Adopt the low speed heavy pressure cast to solve the defectives such as subcutaneous pinhole, cold shut and shrinkage porosite, the die casting qualification rate can reach more than 98%. Filling velocity and solidification and crystallization pressure because of molten metal, can regulate arbitrarily as required, in wider scope, foundry goods to different wall and size can both be suitable for, adopted hot top in the casting mechanism, kept prolonging the service life of charging basket, injection ram, flowability and the feeding effect that improves molten metal had obvious actual effect.
