Abstract
The utility model discloses a special pressure head for a moulding machine for the lower shape moulding of a brake drum on an automatic moulding production line. The special pressure head comprises a rotary oil cylinder, a rotary working table, a compacting platform, a lower shape mould, a sand box, a pressure head, a compacting oil cylinder, a mobile machine body and a sand charging bucket. The special pressure head is mainly characterized in that a compacting lug boss is arranged at the lower part of the pressure head; a reverse circular platform is arranged on the central axial line of the compacting lug boss and welded with the pressure head into an integer, the side angle of the reverse circular platform is the same as the draft angle of the cavity inside the reverse circular platform of the lower shape mould, the large end diameter of the upper part of the reverse circular platform is smaller than the large end diameter of the top of the cavity inside the reverse circular platform of the lower shape mould, and the height of the reverse circular platform is more than the compacting depth of moulding sand pressed into the sand box by the pressure head. According to the special pressure head, the uniformity of compactness of every position of the integral cavity is achieved when the lower shape of the brake drum is moulded, so that the serious surface quality problem that the surface of the brake drum generates burrs and is uneven because the compactness of the cavity is nonuniform, and the purposes of enhancing the surface quality of the brake drum, increasing economic benefit and being simple in structure are realized.
Description
Technical field
The utility model relates to foundry machinery technical field, particularly the moulding machine Special pressing head of the mo(u)ld bottom half moulding of brake rim on a kind of automatic moulding production line.
Background technology
The moulding machine pressure head of the automatic moulding production line of existing import/domestic is all to adopt single pressure head or multiple pressure head to realize moulding machine to the compacting of molding sand.On the automatic moulding production line of single pressure head, the mo(u)ld bottom half moulding of brake rim is exactly, with massive plate pressure head of a compacting hydraulic oil cylinder driving, the identical molding sand of packed height in sandbox is carried out to compacting, between the top of the mo(u)ld bottom half mould in sandbox and inner wall of sand box and the round platform internal cavity compacting depth of mo(u)ld bottom half mould be all the same, cause between the top of mo(u)ld bottom half mould and inner wall of sand box because the molding sand height of filling is little, after compacting, the die cavity degree of packing is up to arriving technical requirement, and the round platform internal cavity of mo(u)ld bottom half mould is because the molding sand height of filling is large, the low technical requirement that do not reach of the die cavity degree of packing of the round platform internal cavity outside of mo(u)ld bottom half mould after compacting, after molten iron cast, cause the brake rim surface thorn that becomes mildewed, uneven, have a strong impact on the surface quality of brake rim, increase disposal costs and clearance time, to production, bring great inconvenience, on a multiple pressure automatic moulding production line, the mo(u)ld bottom half moulding of brake rim is exactly, with each self-driven tablet pressure head of a plurality of compacting oil cylinders, the molding sand everywhere in sandbox is carried out to compacting from top to bottom, although can reach the technical requirement of the degree of packing, but machine construction is complicated, manufacturing cost is high, simultaneously because the top of mo(u)ld bottom half mould and the mold thickness between the inwall of sandbox of brake rim are little, multiple pressure bad installing and using, cannot meet production requirement.No matter adopt single pressure head or adopt multiple pressure head all can not meet the production requirement of the mo(u)ld bottom half moulding of brake rim.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of reach while producing brake rim the whole die cavity degree of packing everywhere evenly, improve brake rim surface quality, increase economic efficiency and automatic moulding production line simple in structure on the moulding machine Special pressing head of brake rim mo(u)ld bottom half moulding.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise angling cylinder, rotary table, compacting platform, mo(u)ld bottom half mould, sandbox, pressure head, compacting oil cylinder, mobile body and add the moulding machine Special pressing head of the mo(u)ld bottom half moulding of brake rim on the automatic moulding production line of sand hopper, the bottom of pressure head is provided with compacting boss.
On the central axis of described compacting boss, be made as inverted round table, be welded as a whole with pressure head, the side gradient of inverted round table is identical with the pattern draft of the round platform internal cavity of mo(u)ld bottom half mould, top outside diameter is less than the outside diameter at top of the round platform internal cavity of mo(u)ld bottom half mould, is highly greater than pressure head and is pressed into the molding sand compacting depth in sandbox.
Usefulness of the present utility model is: because the bottom of the pressure head of moulding machine on automatic moulding production line is provided with the compacting boss of inverted round table, during the mo(u)ld bottom half moulding of brake rim, reach the whole die cavity degree of packing everywhere even, the brake rim surface of causing because the die cavity degree of packing is inhomogeneous become mildewed thorn, rough serious surface quality problems have been solved, realize the surface quality that improves brake rim, simple in structure, increase economic efficiency.
accompanying drawing explanation
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the concrete structure schematic diagram of the moulding machine Special pressing head of the mo(u)ld bottom half moulding of brake rim on a kind of automatic moulding production line the utility model proposes.
In figure: (1) is angling cylinder, (2) be rotary table, (3) are compacting platform, and (4) are mo(u)ld bottom half mould, (5) be the round platform internal cavity of mo(u)ld bottom half mould, (6) be sandbox, (7) are compacting boss, and (8) are pressure head, (9) be compacting oil cylinder, (10) be mobile body, (11) are the top of mo(u)ld bottom half mould, and (12) are for adding sand hopper.
