Description

Technical Field

[0001] The utility model relates to a prepreg line double-layer host device. Background Art

[0002] At present, with the vigorous development of new energy vehicles, the demand for corresponding high-strength and lightweight auto parts is increasing, and the demand for raw material prepreg lines is also increasing. The production of prepreg lines is inseparable from molds. The molds used for prepreg line production generally include an upper mold body and a lower mold body. A mold cavity is provided between the upper mold body and the lower mold body. The extruder squeezes the molten material into the mold cavity. When the tow passes through the mold cavity, the molten material will adhere to the surface. After the molten material solidifies, the prepreg line is obtained. For example, a Chinese patent with publication number CN205009441U discloses a unidirectional fiber pre-impregnated thermoplastic resin composite material forming mold. However, in some molds, only a feed channel is provided in the lower mold body, so the molten material can only flow into the mold cavity from the lower mold body, which will cause the material to enter the mold cavity unevenly, and then cause the material to be unable to be evenly attached to the tow. In order to solve this problem, some companies set feed channels in the upper mold body and the lower mold body respectively, so that the material can enter the mold cavity more evenly.

[0003] In a traditional production line, the extruder is fixed, the lower mold is also fixed, and the upper mold is movable. The extruder and the lower mold can be connected by a hard pipe, and the extruder and the upper mold can be connected by a soft pipe. The molten material in the extruder flows through the hard pipe and flows into the mold cavity from the feed channel in the lower mold, and flows through the soft pipe and flows into the mold cavity from the feed channel in the upper mold. However, during the frequent opening and closing of the mold, the upper mold needs to be repeatedly raised or lowered, which will cause the connection between the soft pipe and the upper mold to be constantly subjected to force, which will cause the connection between the soft pipe and the upper mold to become loose, resulting in a gap at the connection and causing material leakage, so as to affect the normal production of the prepreg line.

[0037] like Figures 1 to 5As shown, a double-layer main machine device of a prepreg line includes a frame 1, a lifting device 100, a first extruder 2, a second extruder 3, a hanging assembly 4, a mold, a first flow channel tube 5 and a second flow channel tube 6;

[0038] The mold includes an upper mold body 7 and a lower mold body 8, wherein the upper mold body 7 is located above the lower mold body 8, and the lower mold body 8 remains fixed during the mold opening and closing process;

[0039] One end of the hanging component 4 is connected to the first extruder 2, and the other end of the hanging component 4 is connected to the upper mold body 7;

[0040] The first extruder 2 is connected to the lifting device 100, and the lifting device 100 is connected to the frame 1. The lifting device 100 is used to drive the first extruder 2 to rise and fall, and then drive the upper mold body 7 to rise and fall synchronously through the hanging assembly 4 to realize mold opening and mold closing;

[0041] One end of the first flow channel tube 5 is connected to the first extruder 2, and the other end of the first flow channel tube 5 is connected to the upper mold body 7;

[0042] One end of the second runner tube 6 is connected to the second extruder 3, and the other end of the second runner tube 6 is connected to the lower mold body 8, and the second extruder 3 is fixedly arranged. Specifically, the first extruder 2 and the upper mold body 7 are connected through the first runner tube 5, and the second extruder 3 and the lower mold body 8 are connected through the second runner tube 6. The molten material in the first extruder 2 flows through the first runner tube 5 and then flows into the mold cavity from the upper mold body 7, and the molten material in the second extruder 3 flows through the second runner tube 6 and then flows into the mold cavity from the lower mold body 8. During the process of opening and closing the mold, the upper mold body 7 is connected to the first extruder 2 through the hanging assembly 4, and the lifting device 100 drives the first extruder 2 to rise and fall, and the first extruder 2 drives the upper mold body 7 to rise and fall synchronously through the hanging assembly 4, so the upper mold body 7 and the first extruder 2 remain relatively still, and the first extruder 2, the upper mold body 7 and the first runner tube 5 rise or fall synchronously as a whole, and remain relatively still with each other, so the connection between the first runner tube 5 and the upper mold body 7 will not be affected by external forces, so that the connection between the first runner tube 5 and the upper mold body 7 will not be loosened, thereby avoiding the problem of material leakage. And during the process of opening and closing the mold, the second extruder 3 and the lower mold body 8 are both stationary, so the second runner tube 6 also remains stationary, so the connection between the second runner tube 6 and the lower mold body 8 will not be loosened due to repeated external forces, so there will be no leakage. The above design can avoid the loose connection between the upper mold body 7 and the lower mold body 8, thereby avoiding the problem of material leakage and ensuring the normal production of the prepreg line. In this embodiment, the first flow channel tube 5 and the second flow channel tube 6 are both hard tubes.

Specifically, when the mold is separated, the lifting cylinder 10 drives the first extruder 2 to rise, and the lifting drive mechanism drives the lifting frame 9 to rise. When the first extruder 2 rises, it can drive the upper mold body 7 to rise synchronously through the hanging component 4, thereby realizing mold separation. When the mold is closed, the lifting drive mechanism first drives the lifting frame 9 to descend and then the first extruder 2 to descend, and the first extruder 2 then drives the upper mold body 7 to descend through the hanging component 4, so that the distance between the upper mold body 7 and the lower mold body 8 is close; then the lifting cylinder 10 drives the first extruder 2 to descend relative to the lifting frame 9, and similarly, the first extruder 2 will also drive the upper mold body 7 to descend to the mold through the hanging component 4. Among them, the lifting cylinder 10 has an air buffering effect, which can prevent the upper mold body 7 and the lower mold body 8 from colliding during the mold closing, thereby avoiding damage to the mold. More specifically, whether in the process of mold separation or mold closing, the first extruder 2, the upper mold body 7 and the first runner tube 5 are synchronously raised or lowered as a whole, and remain relatively still with each other, so the connection between the first runner tube 5 and the upper mold body 7 will not be affected by external forces, thereby preventing the connection from loosening and material leakage.

[0056] like Figure 1 , 2 As shown, the prepreg line double-layer host device may further include a mounting bracket 21;

[0057] The lower mold body 8 is connected to the mounting bracket 21;

[0058] The mounting bracket 21 is connected to a guide rod 22 arranged in the vertical direction, and the connecting plate 19 is slidably connected to the guide rod 22; specifically, when the first extruder 2 is driven to rise and fall, the connecting plate 19 is driven to rise and fall and slide through the suspension rod 20, thereby driving the upper mold body 7 to rise and fall synchronously, thereby realizing the opening and closing of the mold.
