Abstract
The invention belongs to the field of mechanical machining equipment, and relates to a forming mould of a bracket of an upper control rod. The left part and the right part of the mould are symmetrical; a pair of upper dies (3) is symmetrically arranged at the left part and the right part of the upper half part of the mould; a pair of forming top plates (6), a pair of lateral lower dies (4) and a pair of middle lower dies (12) are symmetrically arranged at the left part and the right part of the lower half part of the mould; one ends of top rods (8) are correspondingly arranged below the forming top plates (6), and the other ends of the top rods are correspondingly arranged above top plates (11); the upper dies (3), the lateral lower dies (4), the forming top plates (6) and the middle lower dies (12) respectively form a pair of forming moulds of the bracket of the upper control rod. In the invention, one-time forming of a special piece is realized; a left piece and a right piece are produced in one mould; and the influence of a lateral force on the mould during the processing of a product is eliminated. The mould not only ensures technical requirements and stable quality of the product, but also has high production efficiency; moreover, the production cost is reduced.
Description
Technical field
The invention belongs to the machining equipment field, relate to a kind of upper control lever rack forming mould, particularly a kind of mfg. moulding die for control lever support on the automobile rear driving axle.
Background technology
Upper control lever support is one of important linkage support that is connected with vehicle frame on the rear driving axle, dehisces to install push-off pin in it, and the inclination rigidity of Vehicle Driving Cycle process is provided, and provides comfortableness for car load together with helical spring.
The mode of production of upper control lever support is to adopt double action oil hydraulic press processing, upward the control lever support is different from general support, such as Fig. 5, it is irregular special-shaped support, normal mentality of designing is for using first mold shaped article bottom boss, and then with the twice single-piece work mode of a mold shaped article side, other owing to product divide about part, just need the quadruplet mould to carry out processing and fabricating, operation is tediously long.Because angle of heel is arranged at this product bottom, the side force that occurs during single-piece work easily causes damage to mould in addition.Therefore, need to design and produce out the mould that a cover is different from former scheme, can satisfy the specification requirement of product, can disposablely finish again product about the upper control lever rack forming mould of part processing.
Summary of the invention
The purpose of this invention is to provide a kind of one-shot forming processing profiled about the mfg. moulding die of upper control lever support of part.
The object of the present invention is achieved like this: this mould is divided into the first half of mould and the latter half of mould, the mould left-right symmetry, the first half left-right symmetry that it is characterized in that mould is provided with a pair of patrix, and the latter half left-right symmetry of mould is provided with a pair of shaping top board, an offside counterdie and a pair of middle counterdie; Patrix is corresponding with the position of shaping top board, being provided with lower model fixing seat between the counterdie in the middle of a pair of inserts, the shaping top board is located between side counterdie and the middle counterdie and forms and is slidingly connected, the shaping top board is provided with alignment pin, and the outside of side counterdie is connected with the counterdie fixed head respectively with the below that lower model fixing seat is inserted; Push rod is positioned over by matched in clearance in the bar hole of counterdie fixed head and die shoe, and an end correspondence of push rod is placed on shaping top board below, and other end correspondence is placed on the top board top; Top board is positioned in the die holder backing plate, and counterdie fixed head, die holder backing plate are connected with the upper and lower of die shoe respectively.
Be preferably:
Patrix is located between the upper mould fixed plate, and upper mould fixed plate is connected bolt and pin and is connected with upper bolster with patrix; Guide pin bushing is connected with the dowel hole of upper bolster;
The side counterdie is installed on the side counterdie cushion block, and both are connected with the counterdie fixed head by bolt respectively; Middle lower model fixing seat is inserted and is connected with the counterdie fixed head with bolt by locking key; Middle counterdie is inserted with middle lower model fixing seat by bolt and is connected; Between correspondence one side that one side of side counterdie and side counterdie cushion block and middle counterdie and lower model fixing seat are inserted, be slidingly connected with the formation of shaping top board;
Counterdie fixed head, die holder backing plate are connected with the upper and lower of die shoe respectively by bolt; The fixing collar interference is assemblied on the counterdie fixed head; The guide pillar interference is assemblied on the die shoe;
The single face gap of patrix and side counterdie and the single face gap of patrix and middle counterdie are controlled at except material thickness in the 0.1-0.15mm scope.
The present invention realizes once finishing the moulding of shaped piece, and part about a molded work, and side force is on the impact of mould when having eliminated converted products.This mould has not only guaranteed product technology requirement, steady quality, and production efficiency high, reduced production cost.
