Abstract
The invention discloses an integral type melting cup of a die-casting machine. The integral type melting cup comprises a barrel body which is integrally formed by a left barrel body section and a right barrel body section. The outer diameter of the left barrel body section is larger than that of the right barrel body section. The joint between the left barrel body section and the right barrel body section is provided with a step table which is gradually thinned. An annular groove is formed in the middle of the right barrel body section. The portion, at the right end of the annular groove, of the right barrel body section is provided with a through hole communicated with an inner barrel hole. According to the integral type melting cup of the die-casting machine, the die-casting production cost is reduced; a rear press-shoot head of the integral type melting cup moves in the integral type melting cup instead of a sprue bush; a die-casting product is high in stability, the press-shoot head does not need to pass through the sprue bush in the press-shoot process of the integral type melting cup, and therefore gas involving is avoided; and the production efficiency is high, the melting cup is directly sleeved with an integral type melting cup fixed die, and the debugging speed is high.
Description
technical field:
The present invention relates to die casting equipment, particularly relate to a kind of Integral melting cup of die casting machine.
background technology:
The injection chamber of current domestic Die Casting Industry more than 500 tons die casting machines is all split type, instant molten cup and being connected of sprue bush are separated, in press casting procedure, injection plunger need move between molten cup and sprue bush, this split type molten cup of need and sprue bush fit dimension must be very good, cause patrix to debug the difficulty of axiality.
Current domestic technique level does not also reach, and axiality does not with great difficulty cause and causes expensive damage to injection plunger and molten cup, causes very large unstability factor to die-cast product simultaneously, and split type molten cup volume defect is as follows:
1, Die Casting cost is high: the injection plunger motion in press casting procedure of split type molten cup need move back and forth between sprue bush and molten cup, and injection plunger consumption can be caused so bigger than normal, and injection chamber wearing and tearing are simultaneously very fast;
2, the stability of die-cast product is not high: because split type molten cup axiality is bad, and patrix debugging is difficult, in injection process, often can, with a small amount of air, cause product percent defective high;
3, production efficiency is not high: because split type molten cup is wasted time and energy on upper/lower die, must be adjusted in sprue bush seam by molten cup, and active and inactive mold debugging is difficult.
summary of the invention:
In order to make up prior art problem, the object of this invention is to provide a kind of Integral melting cup of die casting machine, die casting cost can be effectively reduced, improve the stability of die-cast product, enhance productivity.
Technical scheme of the present invention is as follows:
The Integral melting cup of die casting machine, comprise cylindrical shell, it is characterized in that: described cylindrical shell is by left cylinder section and right cylinder section is one-body molded forms, left cylinder section external diameter is greater than right cylinder section external diameter, left cylinder section and right cylinder section junction are provided with tapered ladder platform, be provided with annular groove in the middle part of right cylinder section, the right cylinder section of the right-hand member of annular groove offers the through hole be connected with cylinder bore.
The Integral melting cup of described die casting machine, is characterized in that: described cylinder bore left end not chamfering, and right-hand member is provided with chamfering, general length 2 ~ 5mm, with horizontal plane angle 25 ~ 45 °.
The Integral melting cup of described die casting machine, is characterized in that: the right cylinder section external diameter of the right-hand member of described annular groove is identical with the bottom land external diameter of annular groove.
The Integral melting cup of described die casting machine, is characterized in that: described through hole is scallop hole, and scallop hole is expanded to outer wall gradually by cylinder inboard wall, and scallop hole central angle is 45 ° ~ 65 °, and width is generally 60 ~ 90mm.
Advantage of the present invention is:
1, reduce Die Casting cost, after Integral melting cup, injection plunger moves in Integral melting cup, need not move in sprue bush;
2, the stability of die-cast product is high, and in Integral melting cup injection process, injection plunger does not need through sprue bush, can not cause volume gas phenomenon;
3, production efficiency is high, and Integral melting cup cover half is directly enclosed within molten cup, and debugging speed is fast, and efficiency is high.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A sectional view of the present invention.
detailed description of the invention:
See accompanying drawing:
The Integral melting cup of die casting machine, comprise cylindrical shell 1, cylindrical shell 1 is by left cylinder section and right cylinder section is one-body molded forms, left cylinder section external diameter is greater than right cylinder section external diameter, left cylinder section and right cylinder section junction are provided with tapered ladder platform 2, ladder platform 3, as the axial limit structure after die-casting machine suit, is provided with annular groove 3, the right cylinder section of the right-hand member of annular groove 3 offers the through hole 4 be connected with cylinder bore in the middle part of right cylinder section.
Cylindrical shell 1 endoporus left end does not allow chamfering, and left end and die gate casing port connect, and right-hand member is provided with chamfering 5, length 2 ~ 5mm, with horizontal plane angle 25 ~ 45 °.
The right cylinder section external diameter of the right-hand member of annular groove 3 is identical with the bottom land external diameter of annular groove 3, and annular groove 3 place is axially set with die-casting machine.
Through hole 4 is scallop hole, and scallop hole is expanded to outer wall gradually by cylinder inboard wall, and scallop hole central angle is 45 ° ~ 65 °, and width is generally 60 ~ 90mm.
