One-time forming mold for clutch facing

Abstract

The invention discloses a one-time forming mold for a clutch facing, and relates to a mold. The one-time forming mold comprises a demolding ejection mechanism which is arranged between an upper heating plate and a lower heating plate of a four-column hydraulic press. The one-time forming mold is characterized in that the demolding ejection mechanism comprises an upper mold, a lower mold and a demolding device; the bottom of the lower mold is provided with a carriage; the demolding device is arranged between the upper mold and the carriage; and a workpiece to be machined is arranged between the demolding device and the upper mold. Three procedures are decreased compared with the traditional procedures, the quality and appearance of products are improved, the mold is easy and convenient to operate, and a series of problems of raw material waste, manpower waste, equipment loss and the like are solved.

Description

technical field [0001] The invention relates to a mold, in particular to a one-time molding mold for a clutch face. Background technique [0002] At present, there are many professional manufacturers of automobile clutch facings at home and abroad, and the technology of pressing and forming clutch facings in the same industry is basically the same. At present, the same industry has continued to use open molding molds in the pressing and molding of clutch faces. The defect of this kind of molding molds is that the blanks are placed in the mold and processed by pressure, temperature, and time. After molding, the product is released from the mold. After being squeezed by pressure, a large amount of residual material will be discharged, and the residual material cannot be recycled after being vulcanized. After the product is pressed and formed, it flows into the punching and hole reaming process. The punching of the product is processed according to the size and quantity of th...

Problems solved by technology

At present, the same industry has continued to use open molding molds in the pressing and molding of clutch faces. The defect of this kind of molding molds is that the blanks are placed in the mold and processed by pressure, temperature, and time. After molding, the product is released from the mold. After being squeezed by pressure, a large amount of residual material will be discharged, and the residual material cannot be recycled after being vulcanized

Product punching is processed according to the size and quantity of rivet holes on the customer's drawing (the size and number of holes of the product vary), the product is put into the punching mold and the punching machine is started for processing, and the punched particles cannot be recycled.

The rivet holes in the reaming process need to use a reaming machine to drill off the excess material of the rivet countersunk head, and the remaining material after drilling cannot be recycled.

At the same time, due to the sharp rise in the price of petrochemical materials in the past two years, the combination of various factors such as the increase in labor compensation year by year, and the rapid rise in prices, the burden on enterprises has increased greatly.
