Technical Field
The invention relates to the technical field of manufacturing of automobile brake pads, in particular to an improved brake pad die.
Background
At present, the automobile drum brake pad is pressed and formed and drilled in the following two modes: 1: the barrel type circulating mold is mainly characterized in that weighed raw materials are put into a mold cavity, then a partition plate is added for pressing, and a piece is circulated. The pressing forming size is uneven, the partition plate is taken out of the die to obtain tablets, and the temperature difference is increased. The pressure maintaining process time is difficult to ensure, so that the product is loose, and the performance is unstable. And 2, arranging a mould and cavity-separating a lifting mould, after the process needs to perform in advance, putting a cold blank into the mould cavity, performing secondary hot press forming, wherein the preforming needs to have high raw material fluidity and uneven forming, and the preforming equipment and labor cost are increased. After the two pressing forming modes, the needed rivet holes are machined on the brake pad by special drilling equipment, and the two pressing forming modes are positioned secondarily, so that the appearance size of the brake pad is uneven, and the drilled holes are unstable in size. In the later riveting process of the brake pad and the brake shoe, the rivet is difficult to penetrate, and the hidden trouble that the brake pad is broken due to a gap is left. And the investment of drilling equipment is large, the drill loss and the labor cost are large, dust is generated in the drilling process to pollute the environment, and the input cost of raw materials is increased.
The Chinese patent with the publication number of CN206306351U discloses a brake block mold with a rivet hole, which comprises an upper template and a lower mold cavity which are buckled with each other, an upper pressing head arranged on a buckling surface of the upper template, a middle fixed guide pillar arranged on the upper pressing head, and movable core-pulling guide pillars arranged at two ends of the middle fixed guide pillar and used for pressing the rivet hole, wherein the upper pressing head is provided with a guide pillar hole, the movable core-pulling guide pillars are arranged in the guide pillar hole, and a brake block ejection cylinder is fixedly arranged on the upper pressing head. Practical application finds that the brake block die has the defects of easy blocking of guide post interference, incomplete return stroke, inflexible movement and the like, and has poor reliability.

The improved brake pad die has the following technical effects:
1. the guide post sliding block is adopted, so that guide post interference is avoided, and the brake block is more suitable for brake block products with more and complex hole sites and small hole site included angles;
2. the displacement precision of Kong Daozhu can be controlled more accurately by directly opening the inclined guide groove through the guide pillar slide block;
3. kong Daozhu and the sliding pin column change the surface contact of the original guide column into linear contact, so that the movement is flexible, and the guide column is prevented from being blocked;
4. the product ejection structure adopts mechanical structure, reduces the gas circuit of cylinder and arranges, and mechanical structure can not be because of mould high temperature, action inefficacy, and original hole guide pillar adopts the spring to assist to rebound, because the spring receives mould temperature influence, spring force cuts down, produces the jamming, causes the guide pillar return stroke not in place.
5. The brake pad wear indication line is added, and the pressed brake pad directly carries the wear indication line. Saving raw materials and subsequent processing cost and reducing dust pollution.
