Abstract
The utility model discloses a hard mold core pre-forming mold used for an automobile back shaft support assembly trailing arm beam, and relates to a mold used for producing automobile parts. The hard mold core pre-forming mold used for the automobile back shaft support assembly trailing arm beam comprises an upper mold frame, a concave mold, a lower mold frame and a convex mold, wherein the concave mold is installed on the bottom of the upper mold frame, and the concave mold is provided with a cavity which is provided with a horizontal round groove at one end and is provided with an arc-shaped round groove at the other end; the convex mold is installed on the lower mold frame, and the convex mold is provided with a cavity which is a horizontal surface at one end and is a protruded arc-shaped surface at the other end; and a guide rod is installed between the upper mold frame and the lower frame which are on the periphery of the concave mold and the convex mold. A material returning plate is further installed on the lower mold frame, and an ejection rod penetrating through the lower mold frame is arranged on the bottom of the material returning plate. The hard mold core pre-forming mold used for the automobile back shaft support assembly trailing arm beam is not only high in production efficiency, but also stable in product quality, and therefore mass production requirements can be met.
Description
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 preforming 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. 3～Fig. 4), 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, operation gravity die core preforming is generally to adopt as filling materials such as sands seal the workpiece two ends and need to carry out the moulding of twice ability of bending to workpiece, and its production efficiency is lower; Therefore, the manufacture method of existing bracket of back axle of automobile assembly trailing arm beam can't satisfy the demand of production in enormous quantities.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of gravity die core preforming mould that is used for bracket of back axle of automobile assembly trailing arm beam that can satisfy production demand is provided.
The technical scheme that solves the problems of the technologies described above is: a kind of gravity die core preforming mould for bracket of back axle of automobile assembly trailing arm beam, comprise top mold frame, die, lower mold holder and punch, described die is arranged on the bottom of top mold frame, and it is that horizontal circular trough, the other end are the die cavity of arc circular trough that this die has an end; Described punch is arranged on lower mold holder, and it is that horizontal plane, the other end are the core of protrusion arc face that this punch has an end; Between the top mold frame of described die, punch surrounding and lower mold holder, guide pillar is installed.
Further technical scheme of the present utility model is: stripper also is installed on described lower mold holder, and the bottom of this stripper is provided with the push rod that passes lower mold holder.
Owing to adopting technique scheme, the gravity die core preforming 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. production efficiency is high:
Because the utility model comprises top mold frame, die, lower mold holder and punch, wherein die is arranged on the bottom of top mold frame, and it is that horizontal circular trough, the other end are the die cavity of arc circular trough that this die has an end; Described punch is arranged on lower mold holder, and it is that horizontal plane, the other end are the core of protrusion arc face that this punch has an end; Therefore, the utility model can be that straight pipe, the other end are the preform pipe of arc pipe with the disposable end that strikes out of blank pipe on hydraulic press dexterously, thereby twice moulding of prior art can be become one-shot forming, not only easy to operate, also greatly improved production efficiency.
2. constant product quality:
Because the utility model is to adopt mould to complete the bending of mother tube, therefore, its size is more stable, has guaranteed the reliability of product quality.
Therefore, the utility model not only production efficiency is higher, and its product quality is also more stable, thereby can satisfy production demand.
Below, in conjunction with the accompanying drawings and embodiments the technical characterictic of the gravity die core preforming mould that is used for bracket of back axle of automobile assembly trailing arm beam of the utility model is further described.
