Technical Field

[0001] The utility model relates to the technical field of carbon fiber prepreg molding, in particular to carbon fiber prepreg molding equipment which is convenient for stripping. Background Art

[0002] The prepreg compression molding process is to lay the cut carbon fiber prepreg into the metal mold cavity according to the layer design for pre-forming, and then transfer it to the press to cure and shape it at a certain temperature and pressure, and take out the product after cooling to a low temperature. Compared with other prepreg molding processes, the prepreg compression molding process has higher production efficiency, precise product size and smooth surface, good repeatability of product appearance size, low production cost, and easy mechanization and automation.

[0003] During the material compression molding process, in order to facilitate demoulding, a release agent is often applied to the inner surface of the mold to assist demoulding. In the prior art, this process is usually completed manually, which is dangerous. Even if the release agent is applied, manual assistance is still required for demoulding after compression molding, and the degree of automation is low.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a carbon fiber prepreg molding equipment that is easy to remove is proposed. Utility Model Content

The top of the piston 205 is fixedly connected to the connecting rod 206, and the end of the connecting rod 206 is fixedly connected to the plug 207, and the connecting rod 206 is A spring 208 is provided in the middle part, an air pipe 209 is connected to the bottom side of the air chamber 204, and the input end of the air pipe 209 is connected to the air pump 210. The size of the middle hole 203 matches the shape of the plug 207, and the bottom diameter of the middle hole 203 is smaller than the outer diameter of the spring 208. After compression molding, under the action of the release agent, the carbon fiber prepreg does not fit with the upper mold base 701, but fits tightly in the middle mold cavity of the lower mold base 201. The air pump 210 pumps high-pressure air into the air chamber 204 through the air pipe 209 at the output end. Under the push of the high-pressure air, the piston 205 drives the plug 207 at the end of the connecting rod 206 to separate from the middle hole 203 in the middle of the mold cavity, and pushes the compression-molded carbon fiber prepreg out of the mold cavity of the lower mold base 201. Automatic removal of the carbon fiber prepreg can be achieved without manual assistance, thereby improving the degree of automation of the device.

[0022] like Figures 1 to 3As shown, columns 3 are welded and fixed on both sides of the top of the base 1, and end plates 4 are welded and fixed at the ends of the columns 3. A cylinder 5 is bolted to the middle end of the top of the end plate 4, and a slide plate 6 is fixedly connected to the output end of the cylinder 5, and the slide plate 6 slides with the columns 3 on both sides. A coating component 7 is bolted to the middle end of the bottom of the slide plate 6. The coating component 7 includes an upper mold base 701 and a guide column 702. The guide columns 702 are arranged at the four corners of the upper mold base 701, and the guide columns 702 correspond to the positions of the four guide holes 202. The coating component 7 also includes a mounting plate 703, a swing cylinder 704 and a demoulding agent brush rod 705. The mounting plate 703 is welded and fixed to the side of the upper mold base 701, and the swing cylinder 704 is bolted to the end of the mounting plate 703. The output end of the swing cylinder 704 is fixedly connected to the demoulding agent brush rod 7 05, and the demoulding agent brush rod 705 is in contact with the bottom plane of the upper mold base 701, the smearing component 7 also includes a hose 706 and a squeeze bottle 707, the demoulding agent brush rod 705 is internally connected with the hose 706, and the input end of the hose 706 is connected with the squeeze bottle 707, and the squeeze bottle 707 is made of deformable PE material. The user squeezes the squeeze bottle 707 made of PE material to deform it, and injects the demoulding agent inside it into the demoulding agent brush rod 705 through the hose 706. Thereafter, under the rotation drive of the swing cylinder 704, the demoulding agent brush rod 705 is in contact with the bottom plane of the upper mold base 701 to evenly smear the demoulding agent on the inner surface of the mold, and by arranging the squeeze bottle 707 on the side of the upper mold base 701, the operator does not need to put his hand under the mold to operate, thereby reducing the danger of operation.

After that, under the rotation drive of the swing cylinder 704, the mold release agent brush rod 705 fits the bottom plane of the upper mold base 701 to evenly apply the mold release agent to the inner surface of the mold. By arranging the squeeze bottle 707 on the side of the upper mold base 701, the operator does not need to put his hand under the mold to operate, which reduces the risk of operation. After that, under the push of the oil cylinder 5, the upper mold base 701 located on the lower plane of the slide plate 6 and the upper mold base 701 located on the lower plane of the slide plate 6 are connected. The lower mold base 201 on the upper plane of the base 1 is relatively molded and cured at a certain temperature and pressure. After compression molding, the carbon fiber prepreg does not fit with the upper mold base 701 under the action of the release agent, but fits tightly in the middle mold cavity of the lower mold base 201. The air pump 210 pumps high-pressure air into the air chamber 204 through the output end air pipe 209. Under the push of the high-pressure air, the piston 205 drives the end plug 207 of the connecting rod 206 to disengage from the middle hole 203 in the middle of the mold cavity, and pushes the compression-molded carbon fiber prepreg out of the mold cavity of the lower mold base 201. The automatic removal of the carbon fiber prepreg can be achieved without manual assistance, thereby improving the degree of automation of the device.
