Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to a composite molding device with edge trimming function. Background Technology

[0002] Automotive composite materials are a new type of material system developed in the automotive manufacturing field to achieve lightweighting and improved performance. They are formed by two or more heterogeneous components through a composite process, combining the advantages of each component and having better performance than a single material. In automotive applications, these materials are mainly used in key parts such as body frames, chassis components, and interior panels. Because most interior parts have complex shapes, traditional cutting and splicing processes are not only labor-intensive but also prone to loosening and rattling at the joints. Molding can press fiberglass, non-woven fabric, and other substrates and resin matrices into shape in one step, ensuring the structural integrity of the interior parts and making the material more uniform and less prone to deformation. However, to prevent material shortages during molding, a certain amount of overflow is reserved. These excess parts exceed the design dimensions of the interior parts, so edge trimming is required. If the edges are not trimmed, they will interfere with other parts of the vehicle body during installation and affect the aesthetics of the interior. At the same time, the presence of overflow edges may cause rough edges, which are prone to wear or snagging on clothing during use. Therefore, edge trimming is required again after the interior parts are molded, which adds a production process and equipment investment, extends the production cycle, and increases labor and energy costs. Utility Model Content

[0003] The purpose of this invention is to provide a composite molding device with edge trimming function, which integrates molding and edge trimming, eliminating the need for a separate edge trimming process, shortening the production cycle, reducing costs, and effectively solving the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A composite molding device with trimming function includes a main body, a movable slide table movably connected to the front side of the main body, a lower heating seat fixedly connected to the movable slide table, a hydraulic cylinder fixedly connected to the main body above the lower heating seat, the hydraulic cylinder being connected to a hydraulic station inside the main body via a hydraulic pipe, an upper heating seat fixedly connected to the piston end of the hydraulic cylinder, a positioning trimming mechanism fixedly connected to the lower heating seat, the positioning trimming mechanism further including a base and a cutting tool, a pad fixedly connected to the lower end of the base, side blocks fixedly connected to both sides of the cutting tool, a plurality of connecting rods fixedly connected to the lower end of the side blocks, and the lower ends of the connecting rods movably connected inside the pad.

[0005] As a further preferred embodiment of this utility model, the lower heating seat and the upper heating seat are electrically connected to the main control module inside the main body through connecting lines, thereby realizing composite heating between multi-layer materials to achieve the molding effect between multi-layer materials.

[0006] As a further preferred embodiment of this utility model, the lower heating seat is provided with a first mounting groove to provide installation conditions for the connection and fixation between the base and the lower heating seat. The lower heating seat located on both sides of the first mounting groove is provided with a number of first through grooves to provide a channel for the downward movement of the connecting rod.

[0007] As a further preferred embodiment of this utility model, the pad is provided with a trimming groove along the outer contour of the base. The lower end of the pad is fixedly connected to an installation block, which is inserted into the first installation groove and fixed by bolts. When the cutting tool moves down through the upper heating seat to cut the composite material with the base, the lower end of the cutting tool can be positioned, which facilitates the pressure concentration of the lower end of the cutting tool to cut the composite material.

[0008] As a further preferred embodiment of this utility model, several second through slots are provided in the pads located on both sides of the base. A limiting block is fixedly connected to one side of the second through slot, so that after the lower end of the connecting rod is inserted into the second through slot, the pad and the connecting rod are limited and connected, preventing the connecting rod from separating from the pad.

[0009] As a further preferred embodiment of this utility model, a second mounting groove is provided on one side of the connecting rod, the lower end of the connecting rod is inserted into the second through groove, the second mounting groove is inserted into the limiting block, and a compression spring is inserted into the second mounting groove located above the limiting block.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, by setting a positioning and trimming mechanism on the lower heating seat, the molding and trimming of interior parts can be carried out simultaneously. The cutting tool, in conjunction with the trimming groove, concentrates the cutting pressure, which can avoid problems such as edge burrs and cracks. The cooperation between the connecting rod and the compression spring makes the cutting tool move down smoothly, eliminating the need for subsequent separate trimming, reducing equipment and labor input, significantly shortening the production cycle and reducing energy consumption costs.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-5 As shown, the present invention provides a composite molding device with trimming function, including a main body 1, a movable slide 2 movably connected to the front side of the main body 1, a lower heating seat 3 fixedly connected to the movable slide 2, a hydraulic cylinder 4 fixedly connected to the main body 1 above the lower heating seat 3, the hydraulic cylinder 4 being connected to a hydraulic station inside the main body 1 via a hydraulic pipe, an upper heating seat 5 fixedly connected to the piston end of the hydraulic cylinder 4, a positioning trimming mechanism 6 fixedly connected to the lower heating seat 3, the positioning trimming mechanism 6 also including a base 7 and a cutting tool 8, a pad 9 fixedly connected to the lower end of the base 7, side blocks 10 fixedly connected to both sides of the cutting tool 8, a plurality of connecting rods 11 fixedly connected to the lower end of the side blocks 10, and the lower ends of the connecting rods 11 being movably connected inside the pad 9.

[0015] like Figures 1-2 As shown, the lower heating seat 3 and the upper heating seat 5 are electrically connected to the main control module inside the main body 1 through connecting wires, thereby realizing composite heating between multi-layer materials to achieve the molding effect between multi-layer materials.

[0016] like Figure 2 As shown, the lower heating seat 3 has a first mounting groove 12, which provides installation conditions for the connection and fixation of the base 7 and the lower heating seat 3. The lower heating seat 3 located on both sides of the first mounting groove 12 has several first through grooves 13, which can provide a channel for the downward movement of the connecting rod 11.

[0017] like Figures 3-5As shown, a trimming groove 14 is provided circumferentially along the outer contour of the base 7 on the pad 9. A mounting block 17 is fixedly connected to the lower end of the pad 9, and the mounting block 17 is inserted into the first mounting groove 12 and fixed with bolts. When the cutting tool 8 moves down through the upper heating seat 5 to cooperate with the base 7 to cut the composite material, the lower end of the cutting tool 8 can be positioned, which facilitates the concentrated pressure of the lower end of the cutting tool 8 to cut the composite material. Several second through grooves 1 are provided in the pads 9 located on both sides of the base 7. 5. A limiting block 16 is fixedly connected to one side of the second through groove 15, so that after the lower end of the connecting rod 11 is inserted into the second through groove 15, the pad 9 and the connecting rod 11 are limited to prevent the connecting rod 11 from separating from the pad 9. A second mounting groove 18 is provided on one side of the connecting rod 11. The lower end of the connecting rod 11 is inserted into the second through groove 15, and the second mounting groove 18 is inserted into the limiting block 16. A compression spring 19 is inserted into the second mounting groove 18 located above the limiting block 16.

[0018] It should be noted that this utility model is a composite molding device with trimming function. Before use, the temperature parameters required for molding are set by the main control module of the main body 1. Then, multiple substrates and resin matrix are stacked on the base 7 to ensure that the material completely covers the effective molding area of ​​the base 7. After that, the moving slide 2 is controlled to drive the lower heating seat 3 to move to the position below the upper heating seat 5 to complete the material loading and positioning. Subsequently, the hydraulic station inside the main body 1 supplies oil to the hydraulic cylinder 4 through the hydraulic pipe, pushing the piston end of the hydraulic cylinder 4 to move the upper heating seat 5 downward. At the same time, the lower heating seat 3 and the upper heating seat 5 will start heating under the control of the main control module. As the upper heating seat 5 continues to move downward, it will touch the cutting tool 8, thereby pushing the cutting tool 8 to move downward synchronously. The side blocks 10 on both sides of the cutting tool 8 will drive the connecting rod 11 to slide downward along the second through groove 15. At this time, the compression spring 19 in the second mounting groove 18 will be compressed by the limit block 16. When the cutting tool 8 moves down to contact the pad 9, the composite material will form a shape through the base 7 and the cutting tool 8, and the cutting tool 8 will be aligned with the trimming groove 14. As the pressure applied by the upper heating seat 5 continues to increase, the cutting tool 8 will trim the overflow edge of the molded material along the outer contour of the base 7. The trimming groove 14 can concentrate the pressure of the cutting tool 8 at the blade to achieve the synchronous cutting and molding action.
