Description
Technical Field
The utility model belongs to the technical field of the automobile manufacturing and specifically relates to a preparation mould of brake involucra is related to.
Background
Brake diaphragms, also known as rubber brake diaphragms, are commonly used in automotive brake systems and play a critical role in the brake systems. The outer bottom surface of the bottom of the existing brake membrane is smooth, so that the outer bottom surface of the bottom of the membrane is easy to wear under the repeated jacking action of a push rod in the working process, the bottom of the membrane is finally cracked, and the service life of the brake membrane is shortened. If the brake diaphragm is damaged due to various reasons, the brake of the whole vehicle fails, and traffic accidents of the vehicle are caused, so that the quality of the brake diaphragm must be ensured.
The brake diaphragm is a rubber-sandwiched fabric diaphragm which is suitable for an automobile brake chamber and has the pressure transmission function, the working pressure is 0.5-0.8 MPa, and the working temperature is-40 to +70 ℃. Generally made of NR and a rubber material used together with the NR, and the production adopts a model vulcanization process.
At present, a forming method of an upper die and a lower die is often adopted for manufacturing the brake diaphragm, and the process method can cause the problem that the middle layer of card cloth is not centered, so that the quantity of waste products is increased.
SUMMERY OF THE UTILITY MODEL
In order to the above situation, the utility model provides a preparation mould of brake involucra, this preparation mould of brake involucra has increased the card cloth board, has solved the problem between two parties of card cloth, has reduced scrapping of product.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a preparation mould of brake involucra, includes cope match-plate pattern, well template, lower bolster, and wherein the lower bolster is provided with die, card cloth board, and the die cup joints with card cloth board.
The utility model discloses further preferred scheme: the upper die plate is provided with an upper pressing plate and a first convex block, wherein the upper pressing plate is fixedly connected with the first convex block.
The utility model discloses further preferred scheme: the middle template is provided with a groove and a second bump, wherein the shape of the groove is consistent with that of the first bump, and the groove and the first bump are combined to form a cavity of the inner layer of the skin membrane.
The utility model discloses further preferred scheme: the female die is consistent with the second bump in shape, and the female die and the second bump are combined to form a cavity of the outer layer of the leather membrane.
Compared with the prior art, the utility model has the advantages of:
the utility model provides an increase card cloth board in the preparation mould of brake involucra, the card cloth position that is favorable to the brake involucra is placed in the middle, avoids the product to scrap.
