Abstract
The utility model discloses a special pressing head of a molding machine for feeding and molding a brake drum on an automatic molding production line. The special pressing head comprises a rotary oil cylinder, a rotary working platform, a compacting platform, a mold plate, a feeding mold, a sand box, a pressing head, a compacting oil cylinder, a moving machine body and a sand feeding funnel. The special pressing head is mainly characterized in that a compacting boss is arranged at the lower part of the pressing head; a circular-truncated-cone inner hollow chamber is arranged on the central axis of the compacting boss; a steel structure body of which the shape and the size are identical to those of the pressing head and the height is greater than the compacting depth of molding sand pressed into the sand box is arranged outside the pressing boss; the steel structure body is integrally welded with the pressing head; the side surface inclination degree of the circular-truncated-cone inner hollow chamber is identical to the inclination degree of a shifting mold outside the feeding mold; the diameter of a small end of the upper part of the inner hollow chamber is slightly greater than that of the top of the feeding mold. When the brake drum is fed and molded, the compactness of different parts of the whole molding chamber is uniform, the severe quality problems that the surface of the brake drum has burrs and is rugged as the compactness of the molding chamber is not uniform are solved, and the purposes that the surface quality of the brake drum is improved, the economic benefits are improved and the structure is simple are achieved.
Description
Technical field
The utility model relates to foundry machinery technical field, particularly the moulding machine Special pressing head of the mo(u)ld top 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 the compacting of moulding machine to molding sand.On the automatic moulding production line of single pressure head, the mo(u)ld top 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 top half mould in sandbox and inner wall of sand box and the outside of mo(u)ld top half mould, compacting depth is all the same, cause the top of mo(u)ld top half mould because the molding sand height of filling is little, after compacting, the die cavity degree of packing is up to arriving technical requirement, and between inner wall of sand box and the outside of mo(u)ld top half mould due to fill molding sand height large, the low technical requirement that do not reach of the outside die cavity degree of packing of mo(u)ld top 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, give and produce, sell, installation and use bring great inconvenience, on a multiple pressure automatic moulding production line, the mo(u)ld top half moulding of brake rim is exactly, with the each self-driven tablet pressure head of multiple 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 complexity, manufacturing cost is high, while is because the mold thickness between the outside of the mo(u)ld top half mould of inner wall of sand box and brake rim is 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 top 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 top 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, template, mo(u)ld top half mould, sandbox, pressure head, compacting oil cylinder, mobile body and add the moulding machine Special pressing head of the mo(u)ld top 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 round platform internal cavity, that outside is made as is identical with the shape and size of pressure head, be highly greater than pressure head is pressed into the steel structure body of the molding sand compacting depth in sandbox, is welded as a whole with pressure head.
The side gradient of described round platform internal cavity is identical with the outside pattern draft of mo(u)ld top half mould, and top end diameter is a bit larger tham the diameter at the top of mo(u)ld top half mould.
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 internal cavity that is made as round platform on central axis, outside is made as identical with the shape and size of pressure head, highly be greater than the compacting boss that pressure head is pressed into the steel structure body of the molding sand compacting depth in sandbox and is welded as a whole with pressure head, when the mo(u)ld top half moulding of brake rim, reach the whole die cavity degree of packing everywhere even, solve the brake rim surface of causing because the die cavity degree of packing the is inhomogeneous thorn that becomes mildewed, rough serious surface quality problems, realize the surface quality that improves brake rim, simple in structure, increase economic efficiency.
brief description of the drawings
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 top half moulding of brake rim on a kind of automatic moulding production line the utility model proposes.
