Abstract

A hard mold core forming mold used for producing an automobile back shaft support assembly trailing arm beam comprises an upper mold frame, a convex mold, a lower mold frame and a concave mold, wherein the convex mold is installed on the bottom of the upper mold frame through a convex mold padding plate, and the convex mold is provided with a mold core which is inclined at one end, horizontal at the other end and curved in the middle; and the concave mold is installed on the lower mold frame, and the concave mold is provided with a cavity which is in accordance with the convex mold core in shape. A material returning plate is further installed on the lower mold frame, and an ejection rod penetrating through the lower mold frame is installed on the material returning plate. According to the hard mold core forming mold used for producing the automobile back shaft support assembly trailing arm beam, not only is production free of equipment failure threatening, but also production cost can be greatly reduced, and the hard mold core forming mold used for producing the automobile back shaft support assembly trailing arm beam is suitable for being popularized and used in micro-small enterprises.

Description

Gravity die core mould for the production of bracket of back axle of automobile assembly trailing arm beam

Technical field

The utility model relates to a kind of mould for the manufacture of auto parts and components, particularly a kind of gravity die core mould for bracket of back axle of automobile assembly trailing arm beam.

Background technology

Bracket of back axle of automobile assembly trailing arm beam is that an end is that the straight flat tube of inclination, the other end are that the straight flat tube of level, centre are the non-uniform beam of the curved flat tube of multistage variable cross-section, this trailing arm beam is provided with a breach in the end of the straight flat tube end that tilts, have a circular hole (referring to Fig. 5～Fig. 6), its manufacture difficulty is larger on the curved flat tube of multistage variable cross-section of centre.The manufacture method of existing bracket of back axle of automobile assembly trailing arm beam generally comprises following operation: severing, gravity die core preforming, the moulding of gravity die core, shaping, cutting, boring; Wherein, the moulding of operation gravity die core generally need to design and purchase special equipment and could produce, and its cost is higher, in case and equipment break down, will face the risk of stopping production, thereby be difficult to use at the microminiature business enterprise expand.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of gravity die core mould for bracket of back axle of automobile assembly trailing arm beam is provided, with solve the above-mentioned cost that prior art exists higher, be unsuitable for the weak point applied in microminiature enterprise.

The technical scheme that solves the problems of the technologies described above is: a kind of gravity die core mould for bracket of back axle of automobile assembly trailing arm beam, comprise top mold frame, punch, lower mold holder and die, described punch is arranged on the bottom of top mold frame by convex mould pad, this punch has an end inclination, an end level, middlely is the core of curve; Described die is arranged on lower mold holder, and this die has the die cavity consistent with punch core shape.

Further technical scheme of the present utility model is: stripper also is installed on described lower mold holder, the push rod that passes lower mold holder is installed on this stripper.

Owing to adopting technique scheme, the gravity die core mould that is used for bracket of back axle of automobile assembly trailing arm beam of the utility model compared with prior art has following beneficial effect:

1. because the utility model comprises top mold frame, punch, lower mold holder and die, described punch is arranged on the bottom of top mold frame by convex mould pad, and this punch has an end inclination, an end level, middlely is the core of curve; Described die is arranged on lower mold holder, and this die has the die cavity consistent with punch core shape.Therefore, the utility model is workpiece to be struck out an end on existing general hydraulic press to be the straight flat tube of level, middlely to be the variable cross-section rectangle hollow pipe of the curved flat tube of multistage variable cross-section for the straight flat tube that tilts, an end, need not to design in addition and purchase special equipment, not only can make production not be subjected to the threat of equipment fault, and can greatly reduce production costs.

2. constant product quality:

Because the utility model is to complete the shaping of workpiece by mould, its size is more stable, has guaranteed the reliability of product quality.

Therefore, production cost of the present utility model is lower, is suitable for applying in microminiature enterprise.

Below, in conjunction with the accompanying drawings and embodiments the technical characterictic of the gravity die core mould that is used for bracket of back axle of automobile assembly trailing arm beam of the utility model is further described.
