Abstract

The utility model provides a forming die for automobile windscreen wiper lower reinforcing plates. With production efficiency and qualified rate guaranteed, the forming die is convenient to maintain, maintenance cost is lowered, and production cost is further lowered. The forming die comprises an upper plate and a lower plate which are connected through a guide pillar and a guide bush, an upper die structure is mounted below the upper plate, a lower die structure is mounted on the lower plate, and the forming die is characterized in that the upper die structure comprises a male die and three upper embossing inserts, the three upper embossing inserts correspond to embossing portions of a to-be-processed lower reinforcing plate and are inserted in the male die, the lower die structure comprises an ejector block and lower embossing inserts, and the lower embossing inserts are distributed on two transverse sides of the ejector block and correspond to the embossing portions of the to-be-processed lower reinforcing plate.

Description

A kind of mould of wiper lower reinforcing plate

Technical field

The utility model relates to the stamping technology field of auto parts and components, relates in particular to wiper lower reinforcing plate processing unit (plant) technical field, is specially a kind of mould of wiper lower reinforcing plate.

Background technology

Tradition windscreen wiper lower reinforcing plate 24 as shown in Figure 4, the lower reinforcing plate mould mostly is the progressive die, its shaping and beading are finished simultaneously, its production efficiency is high, percent defective is low, but because mould beading position is damaged easily, maintenance difficulty is large, cause maintenance cost high, further strengthened production cost.

Summary of the invention

For the problems referred to above, the utility model provides a kind of mould of wiper lower reinforcing plate, and when guaranteeing its production efficiency and qualification rate, the mould easy maintenance has reduced maintenance cost, has further reduced production cost.

Its technical scheme is such, it comprises cope match-plate pattern and lower bolster, described cope match-plate pattern be connected lower bolster and connect by guide pillar, guide pin bushing, under the described cope match-plate pattern upper die structure is installed, on the described lower bolster lower die structure is installed, it is characterized in that: described upper die structure comprises on punch and the beading to be inserted, and inserts on the described beading to be provided with three, and corresponding lower reinforcing plate beading to be processed position, inserts insert in described punch on described three beadings; Described lower die structure comprises under ejection block and the beading to be inserted, and inserts under the described beading to be distributed in described ejection block both lateral sides, and corresponding lower reinforcing plate beading to be processed position.

Its further feature with:

Described upper die structure also comprises upper padding plate, and described punch is installed under the described upper padding plate, and described upper padding plate is fixed under the described cope match-plate pattern;

Described lower die structure also comprises bottom plate, lower bolster, described ejection block is installed on the described bottom plate, insert insert under the described beading in described bottom plate, described bottom plate is installed on the described lower bolster, described lower bolster is fixed on the described lower bolster, and described ejection block is fixed in described bottom plate by the location mold insert;

Corresponding its locating hole of lower reinforcing plate to be processed in described ejection block center is equipped with locating pin, and the corresponding lower reinforcing plate lateral profile to be processed of described bottom plate is equipped with banking pin.

After adopting the utility model, its beneficial effect is: its beading position of mould adopts the method for insert mold insert to replace original progressive die, so that the maintenance of the flimsy beading of mould position is simpler and easy, has reduced maintenance cost, improve simultaneously the mold use life-span, further reduced production cost.
