Description

Technical Field

[0001] The present application belongs to the technical field of pultruded carbon plate manufacturing, and specifically relates to a mold for producing pultruded carbon plates without a release cloth. Background Art

[0002] During the production process of pultruded carbon plates, several carbon fibers are solidified together by resin and then placed in a mold for cooling, thereby forming a pultruded carbon plate. After the pultruded carbon plate solidifies in the mold, a demoulding cloth will be set in the mold for easy demoulding, so that after cooling, the pultruded carbon plate will not stick to the mold, which is convenient for demoulding; however, the demoulding cloth will stick to the pultruded carbon plate after it leaves the mold, and leave the mold together with the pultruded carbon plate, and then be packaged together with the pultruded carbon plate. That is, the demoulding cloth on the pultruded carbon plate is not removed when the finished pultruded carbon plate leaves the factory, because doing so can reduce the process of tearing the demoulding cloth off the pultruded carbon plate, thereby saving manpower. The demoulding cloth is not removed until the customer uses the pultruded carbon plate. Although this reduces a process step and can reduce costs, the release cloth is wasted. That is to say, if the release cloth can be recycled, the production cost can be further reduced. Therefore, it is necessary to explore ways to tear the release cloth off the pultruded carbon plate and reuse it without increasing manpower input to reduce the production cost of pultruded carbon plate. Summary of the invention

By setting an automatic upper release cloth pick-up and placement sequencer that cooperates with the upper mold and an automatic lower release cloth pick-up and placement sequencer that cooperates with the lower mold, a mold for producing pultruded carbon plates without a release cloth is designed. In this way, in the process of manufacturing pultruded carbon plates, after the pultruded carbon plates leave the upper mold and the lower mold, the release cloth attached to the pultruded carbon plates can be torn off and reused, thereby solving the problem of how to tear off the release cloth from the pultruded carbon plates and reuse them without increasing manpower input to reduce the production cost of the pultruded carbon plates.
