Description

Technical Field

[0001] The utility model relates to a prepreg tape mould device. Background Art

[0002] At present, prepreg tapes have a large number of applications in the fields of medical equipment and automobile lightweighting. Prepreg tapes can be used to make automobile accessories such as automobile floors, anti-collision beams, seats, and can also be used to make medical bed boards and medical equipment. In the production process of prepreg tapes, a mold is required to attach the prepreg to the surface of the tow. During production, the mold is filled with molten prepreg, and the tow passes through the mold so that the molten prepreg adheres to the surface of the tow. For example, a prepreg tape mold is disclosed in a Chinese patent with publication number CN112477204A, but it is found in the actual production process that when the tow passes through the mold, the tow will diffuse to both sides, which will cause the size specifications of the produced prepreg to be unqualified, and the existing mold cannot limit the diffusion of the tow to both sides.

Specifically, after the filament bundle passes through the mold cavity 1, the prepreg in the mold cavity 1 will fully adhere to the surface of the filament bundle. Since the filament bundle passes between the left blocking wheel 2 and the right blocking wheel 3, when the filament bundle spreads to both sides, the filament bundles on both sides will resist the left blocking wheel 2 and the right blocking wheel 3. The blocking and limiting effect of the left blocking wheel 2 and the right blocking wheel 3 can limit the filament bundle between the left blocking wheel 2 and the right blocking wheel 3 to prevent the filament bundle from spreading to both sides, so that the size specifications of the produced prepreg tape can meet the requirements, and a qualified prepreg tape can be produced.

[0046] like Figure 5 As shown, at least a portion of the mold cavity 1 is a wavy structure, so that the impregnation area of ​​the filament bundle in the mold cavity 1 can be effectively increased, so that the filament bundle and the prepreg are fully contacted to obtain a better impregnation effect, and the filament bundle and the prepreg are fully bonded.

[0047] like Figure 5 As shown, the upper mold body 7 and the lower mold body 8 are respectively provided with a material channel 9 connected to the mold cavity 1, and the inner wall of the mold cavity 1 and the inner wall of the material channel 9 are both provided with a chrome-plated polishing layer; specifically, the surface of the chrome-plated polishing layer has a high degree of smoothness, which can effectively prevent the occurrence of material hanging inside, thereby ensuring the quality of the prepreg tape.

[0048] like Figure 1 , 2As shown, the prepreg tape mold device can also include an upper feed pipe 10 and a lower feed pipe 11, the upper feed pipe 10 is connected to the material channel 9 in the upper mold body 7, and the lower feed pipe 11 is connected to the material channel 9 in the lower mold body 8; specifically, the extruder is respectively connected to the upper feed pipe 10 and the lower feed pipe 11, the extruder squeezes the molten prepreg into the upper feed pipe 10 and the lower feed pipe 11, the material in the upper feed pipe 10 flows through the material channel 9 in the upper mold body 7 and then flows into the mold cavity 1, the material in the lower feed pipe 11 flows through the material channel 9 in the lower mold body 8 and then flows into the mold cavity 1, so that the mold cavity 1 is always filled with prepreg.

[0049] like Figure 1 , 2 As shown in Figure 5, the prepreg tape mold device may also include a first aggregate trough 12 and a second aggregate trough 13, wherein the first aggregate trough 12 is located below the inlet end of the mold cavity 1, and the second aggregate trough 13 is located below the outlet end of the mold cavity 1; in this embodiment, the first aggregate trough 12 and the second aggregate trough 13 are both connected to the lower mold body 8, and the first aggregate trough 12 and the second aggregate trough 13 can collect the prepreg that is not completely attached to the filament bundle, thereby avoiding the dripping of the prepreg to pollute the site, thereby improving the production environment.

[0050] like Figure 1 , 2 As shown in , 5 and 6, the prepreg tape mold device may further include a base frame 14, a left mounting plate 15, a right mounting plate 16, a left guide post 17, a right guide post 18, a left slide plate 19, a right slide plate 20, at least one left adjusting screw rod 21 and at least one right adjusting screw rod 22;

[0055] The upper mold body 7 is located above the lower mold body 8, one end of the upper mold body 7 is connected to the left slide 19, and the other end of the upper mold body 7 is connected to the right slide 20; specifically, the height of the left mounting plate 15 can be adjusted by rotating the left adjusting screw 21, and the height of the right mounting plate 16 can be adjusted by rotating the right adjusting screw 22, thereby adjusting the height of the lower mold body 8, and thereby adjusting the center height of the upper mold body 7 and the lower mold body 8 after the mold is closed, thereby avoiding the situation where the center height of the production line is inconsistent due to uneven ground. More specifically, when the mold is separated, the upper mold body 7 is driven to rise, and at the same time, the left slide 19 slides upward along the left guide column 17, and the right slide 20 slides upward along the right guide column 18, and the left slide 19 and the right slide 20 can guide the upper mold body 7 to rise upward; wherein, the upper mold body 7 can be driven to rise and fall by a cylinder.

[0057] In summary, after the filament bundle passes through the mold cavity 1, the prepreg in the mold cavity 1 will be fully attached to the surface of the filament bundle. Since the filament bundle passes between the left blocking wheel 2 and the right blocking wheel 3, when the filament bundle spreads to both sides, the filament bundle on both sides will resist the left blocking wheel 2 and the right blocking wheel 3. The blocking and limiting effect of the left blocking wheel 2 and the right blocking wheel 3 can limit the filament bundle between the left blocking wheel 2 and the right blocking wheel 3 to prevent the filament bundle from spreading to both sides, so that the size specifications of the produced prepreg tape can meet the requirements, and qualified prepreg tape can be produced.
