Description

Rubber contraflexure mould
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of rubber contraflexure mould.
Background technology
Crooked part is one of punching parts that quantity was maximum during Modern Industry Products, automobile, electrical equipment, instrument and instrument were made.The crooked part major part adopts bending die to process, existing bending die comprises punch and die, punch is descending under the drive of forcing press, workpiece is finished brake forming under the acting in conjunction of punch and die, for precision and the surface quality that improves crooked part, just must add structures such as top board or bullet apical organ, and will improve the precision of punch and die, make the mould structure complexity like this, the manufacturing cost height.
The utility model content
At the problem that above-mentioned prior art exists, the utility model provides a kind of rubber contraflexure mould, can improve the precision and the surface quality of crooked part, and mould structure is simple, and low cost of manufacture is very practical.
The technical solution of the utility model is: a kind of rubber contraflexure mould, comprise upper bolster, die shoe and punch, upper bolster is provided with die shank, punch is fixedly connected on the die shoe upper surface by convex mould base, described upper bolster lower surface is provided with the appearance frame, hold the frame lower surface position corresponding and have the through hole that cooperates with convex mould base with convex mould base, be provided with the moulding die-cushion in the through hole, be provided with the support die-cushion between moulding die-cushion and the upper bolster, described support die-cushion adopts natural rubber to make, described moulding die-cushion adopts polyurethane rubber to make, and supports and is provided with the rod that is shaped between die-cushion and the moulding die-cushion; Punch is provided with location-plate, and location-plate is provided with alignment pin, and the punch upper surface has the hole with the alignment pin coupling, and location-plate removably connects by alignment pin and punch.
As preferably, described upper bolster and die shoe adopt the Q235 steel plate to make.
The beneficial effects of the utility model are: the die that the utility model adopts appearance frame support die-cushion interior with being arranged on the appearance frame and moulding die-cushion to replace the conventional bending mould, support die-cushion and adopt natural rubber, can reduce die manufacturing cost significantly, the moulding die-cushion adopts polyurethane rubber to make, polyurethane rubber is a kind of elastomer, in BENDING PROCESS, hold in the frame and be in closed state, thereby the moulding die-cushion has liquid static pressure after stressed, and promptly the suffered unit pressure of shaping mould pad all directions equates.Downward when the descending drive die shank of press ram, the moulding die-cushion is subjected to punch and the pressure of the rod that is shaped, and forces workpiece to bend along the punch outer peripheral contour.In whole BENDING PROCESS, crooked pressure is even, has reduced resilience, has improved the product precision.And workpiece is in formation state all the time, has improved surface quality of products.Do not need to be provided with in addition top board or play apical organ, also do not need punch is carried out fine finishining, mould structure is simple, low cost of manufacture.Upper bolster and die shoe adopt the Q235 steel plate to make good combination property, long service life.Very practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of rubber contraflexure mould comprises upper bolster 1, die shoe 2 and punch 4, and in the present embodiment, as preferably, described upper bolster 1 and die shoe 2 adopt the Q235 steel plates to make.Its good combination property, long service life.Upper bolster 1 is provided with die shank 3, punch 4 is fixedly connected on die shoe 2 upper surfaces by convex mould base 5, described upper bolster 1 lower surface is provided with and holds frame 6, hold frame 6 lower surfaces and convex mould base 5 corresponding positions and have the through hole that cooperates with convex mould base 5, be provided with moulding die-cushion 11 in the through hole, be provided with between moulding die-cushion 11 and the upper bolster 1 and support die-cushion 7, described support die-cushion 7 adopts natural rubber to make, described moulding die-cushion 11 adopts polyurethane rubber to make, and supports and is provided with the rod 8 that is shaped between die-cushion 7 and the moulding die-cushion 11; Punch 4 is provided with location-plate 9, and location-plate 9 is provided with alignment pin 10, and punch 4 upper surfaces have the hole with alignment pin 10 couplings, and location-plate 9 removably connects by alignment pin 10 and punch 4.
In the present embodiment, as preferably, convex mould base 5 upper surfaces have a cross section and are down trapezoidal groove, and punch 4 is installed on the groove bottom surface, and falling the sidewall of trapezoidal groove and the angle of vertical plane is 15 °~30 °.Adopt such structure to strengthen the lateral pressure of 11 pairs of crooked parts of moulding die-cushion, further improved the precision of workpiece.
