Description

Technical Field

[0001] The present application relates to the technical field of automobile trim production, and in particular to a molding device for composite automobile trim. Background Art

[0002] As the automotive industry develops towards lightweight and environmentally friendly manufacturing, composite materials have gradually become an important choice for automotive accessories due to their excellent performance. However, in the actual production process of composite automotive accessories, problems such as unstable molding quality and low production efficiency have always plagued manufacturers. In existing technologies, using different molds to process according to the different shapes of automotive accessories is the most reliable solution after integrating existing technologies and is also widely used.

[0003] According to a hot pressing forming device for automobile interior parts disclosed in Chinese patent publication No. CN220242202U, the device includes a base, a box body is fixedly installed on the top of the base, and fixed blocks are fixedly installed on the left and right ends of the back of the box body. By arranging a lower mold, a threaded rod and an air jet pipe, when the automobile interior parts are hot pressed, due to the operation of the servo motor, the threaded rod drives the automobile interior parts raw material inside another lower mold through the connecting block for hot processing, and the automobile interior parts after hot pressing are moved to the bottom of the air jet pipe. Then, due to the operation of the air cooler, the exhaust pipe draws in the external gas and converts it into cold air flow, and then the cold air flow is ejected through the bifurcation pipe and the air jet pipe in turn to cool the automobile interior parts after hot pressing. Such reciprocating operation enables the device to alternately cool the automobile interior parts.

[0004] However, this patent still has certain shortcomings in actual use. Since the automotive accessories formed by hot pressing need to be cooled and shaped, and the upper and lower molding molds need to be in a pressed state all the time during the cooling and shaping process to prevent the shape from being changed due to thermal expansion and contraction, the solution of this patent to move the accessories to the other side for cooling after hot pressing will undoubtedly have the problem of shape being changed during cooling and contraction, affecting the overall quality, resulting in practical use being relatively useless. Moreover, when the upper and lower molding molds need to be replaced, this patent cannot conveniently position the upper and lower molding molds so that the positions of the two correspond, and manual adjustment tools are required, which is very inconvenient. In this regard, the present application provides a molding device for composite automotive accessories to solve the above problems. Utility Model Content

[0015] Furthermore, a cooling mechanism located on the back side of the lower die is fixedly installed on the top of the processing box, and two sliding grooves for inserting and slidingly connecting two slide rails are opened on the top of the adjustment block.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] See also Figures 1 to 4 The present application provides a technical solution: a molding device for composite automotive accessories, comprising a processing chassis 1, a power assembly 200 is installed on the top of the processing chassis 1, a mold assembly 300 is installed on the top of the processing chassis 1, and a lower mold 4 is detachably connected to the top of the processing chassis 1; through the coordinated use of the power assembly 200 on the top of the processing chassis 1 and the mold assembly 300 and the lower mold 4, the overall work efficiency can be further improved, and the upper and lower molding molds can be easily positioned and adjusted after replacement, thereby saving the adjustment time of the staff and improving the overall efficiency of the operation, thereby improving the overall work efficiency to a certain extent, simplifying the work intensity and technical threshold of the operator, making the coordination between the structures more practical and effective, thereby greatly improving the practicality of the automotive accessories molding device.

[0032] In this embodiment, the mold assembly 300 is a structure used for pressing and molding composite automotive trims and is convenient for replacing and adjusting the upper and lower molding molds.

[0033] like Figure 2 、 Figure 3 and Figure 4 As shown, the mold assembly 300 includes a fixed plate 301, two slide rails 302 fixedly mounted on the bottom of the fixed plate 301, an adjustment block 303 slidably connected between the outer sides of the two slide rails 302, two trapezoidal grooves 304 provided at the bottom of the adjustment block 303, a trapezoidal block 305 inserted and slidably connected to the inner sides of the trapezoidal grooves 304, a mounting plate 306 fixed between the bottoms of the two trapezoidal blocks 305, a plurality of positioning plates 307 fixed on the top of the mounting plate 306, and an upper mold fixedly mounted on the bottom of the mounting plate 306. 308, two symmetrical plates 309 fixed to the bottom of the fixed plate 301 and located above the mounting plate 306, a screw rod 310 rotatably connected between the opposite sides of the two symmetrical plates 309 through a bearing, a servo motor 311 fixedly mounted on the front side of the front symmetrical plate 309, four laser sensors 312 fixedly mounted on the bottom of the mounting plate 306, four shielding plates 313 fixed to the outside of the lower mold 4, a through hole 314 opened at the top of the shielding plate 313, and four receiving plates 315 fixedly mounted on the outside of the lower mold 4.

[0034] It should be noted that a heating mechanism is integrated inside the upper mold 308. The position of the upper mold 308 corresponds to the position of the lower mold 4, and the shape of the upper mold 308 matches the inner side of the lower mold 4. The heating mechanism can be an electric heating tube, which can heat the prefabricated composite material through the upper mold 308, and then the prefabricated composite material can be shaped by the pressing action between the upper mold 308 and the lower mold 4. A cooling mechanism located on the back side of the lower mold 4 is fixedly installed on the top of the processing chassis 1, so that the cooling mechanism can cool the lower mold 4. The cooling mechanism can be an industrial cooling wind conveying equipment such as an air cooler.

[0035] In addition, the top of the adjustment block 303 is provided with two sliding grooves for the two slide rails 302 to be plugged in and slidably connected. The left and right sides of the slide rails 302 are concave, so that the slide rails 302 can slide and support the adjustment block 303 through the sliding grooves. The front of the trapezoidal groove 304 is open, so that the trapezoidal block 305 can enter normally. The adjustment block 303 is located between the opposite sides of the two symmetrical plates 309. The front of the adjustment block 303 is provided with an internal threaded hole for the screw rod 310 to pass through and be threadedly connected. The output shaft of the servo motor 311 passes through the front of the front symmetrical plate 309 and is fixedly connected to the front end of the screw rod 310, so that the servo motor 311 can drive the screw rod 310 to rotate, and then drive the adjustment block 303 to adjust its position through the threaded connection between the screw rod 310 and the internal threaded hole.

[0036] At the same time, the four laser sensors 312 are respectively located at the four corners of the bottom of the mounting plate 306, and the four shielding pieces 313 correspond to the positions of the four laser sensors 312 respectively. The receiving plate 315 is located below the corresponding shielding piece 313 and is blocked by the corresponding shielding piece 313. Specifically, the area of the shielding piece 313 is larger than the area of the receiving plate 315, so that the top of the receiving plate 315 can be blocked. The transmitting end of the laser sensor 312 corresponds to the position of the corresponding through hole 314, so that the laser emitted by the transmitting end of the laser sensor 312 can only be transmitted to the receiving plate 315 through the through hole 314, thereby improving the adjustment accuracy and facilitating accurate and effective adjustment work.

[0037] In this embodiment, the power assembly 200 is a structure for providing pressing power for the molding operation.

[0038] like Figure 1 and Figure 2 As shown, the power assembly 200 includes four columns 201 fixed on the top of the processing machine box 1, a top plate 202 fixed between the tops of the four columns 201, a hydraulic cylinder 203 fixedly installed on the top of the top plate 202, two linear slides 204 fixed on the top of the top plate 202, and a sliding rod 205 passing through and slidably connected to the inner side of the linear slide 204.

[0039] It should be noted that the output shaft of the hydraulic cylinder 203 passes through the top of the top plate 202 and is fixedly connected to the top of the fixed plate 301. The bottom end of the slide rod 205 passes through the bottom of the corresponding linear slide 204 and the top of the top plate 202 in turn and is fixedly connected to the top of the fixed plate 301. The top of the linear slide 204 is open, so that the fixed plate 301 can be driven by the hydraulic cylinder 203 to move up and down normally under the sliding limit action between the two slide rods 205 and the linear slide 204.

[0040] The working principle of the above embodiment is:

[0041] When processing automobile accessories, the prefabricated composite material is placed inside the lower mold 4, and the hydraulic cylinder 203 is started to drive the fixed plate 301 to move downward, so that the upper mold 308 moves downward and closes the mold with the lower mold 4. The prefabricated composite material can be heated and softened by the heating structure inside the upper mold 308, and then formed into a specific shape under the action of pressure. After cooling, the upper mold 308 can be moved away from the lower mold 4, which is convenient for taking out the internal automobile accessories. When it is necessary to replace the upper mold 308 and the lower mold 4, the lower mold 4 is disassembled and replaced directly, the positioning plate 307 is disassembled, and the trapezoidal block 305 is moved out from the inner side of the corresponding trapezoidal groove 304 to complete the process. To disassemble the upper mold 308, the above principle is reversed and the replaced upper mold 308 is positioned by sliding the trapezoidal block 305 and the trapezoidal groove 304 together. The positioning plate 307 and the adjustment block 303 are then locked to complete the installation of the upper mold 308. The servo motor 311 is started to drive the screw rod 310 to rotate. With the limited cooperation of the two slide rails 302, the adjustment block 303 can be moved and adjusted, and the laser emitted by the laser sensor 312 is passed through the corresponding through hole 314 and is received and reflected by the receiving plate 315. The adjustment of the upper mold 308 is completed without the need for tedious manual adjustment, which facilitates efficient and convenient processing.

[0042] Compared with the existing technology, the molding device for composite automotive accessories can further improve the overall work efficiency by processing the power component 200 on the top of the chassis 1 and the coordination between the mold component 300 and the lower mold 4. The upper and lower molding molds can be easily positioned and adjusted after replacement, thereby saving the adjustment time of the staff and improving the overall efficiency of the operation, so that the overall work efficiency can be improved to a certain extent, and the work intensity and technical threshold of the operator can be simplified, so that the coordination between the structures can be more practical and effective, thereby greatly improving the practicality of the automotive accessories molding device, and solving the problem that the existing hot pressing molding device cannot conveniently position the upper and lower molding molds during actual use, resulting in a certain impact on the actual work efficiency.
