Description

Technical Field

[0001] This invention relates to an injection molding apparatus and method for processing plant fiber composite automotive interior parts, belonging to the technical field of injection molding apparatus. Background Technology

[0002] There are many existing technologies for injection molding of plant fiber composite automotive interior parts. For example, in the prior art, publication number CN112659478B entitled "Injection Molding Device for Automotive Interior Parts," this technical solution includes a horizontally arranged support mounting plate, a working mounting plate horizontally arranged directly above the support mounting plate, a vertically arranged lifting mounting frame at the upper middle position of the working mounting plate, and symmetrically arranged fixed mounting plates at the upper end of the lifting mounting frame. Each fixed mounting plate has fixed mounting holes. The middle area opposite to the support mounting plate and the working mounting plate both have recessed working mounting grooves. Limiting guide cylinders are vertically arranged at both ends of the upper and lower working mounting grooves. The opening is positioned and installed... The combined structure allows the device to adapt to different upper and lower molds, process different automotive interior injection molded parts, and, with multiple injection holes, achieve the production of multiple injection molded parts in a single operation. Simultaneously, rapid heat conduction significantly improves the molding speed of injection molded parts, shortens the demolding cycle, and greatly enhances the production efficiency of automotive interior injection molded parts. Although existing technologies can increase molding speed through rapid heat conduction, they cannot achieve quick and convenient demolding, and may even cause parts to get stuck and difficult to remove. Furthermore, existing technologies cannot achieve rapid injection and rapid closure of injection holes during injection molding. Therefore, a plant fiber composite material automotive interior injection molding device and method are designed to solve the above problems. Summary of the Invention

[0031] Beneficial technical effects of the present invention:

[0032] This invention provides an injection molding apparatus and method for processing plant fiber composite automotive interior parts. The method involves activating an electric lifting frame to lower the top mold, pressing aluminum foil between the top and bottom molds, and cutting the aluminum foil through contact between the top and bottom molds. Under the pressure of the top mold, the lower aluminum foil is pressed against the bottom of the bottom mold, while the upper aluminum foil adheres to the top of the top mold. A high-temperature liquid containing the plant fiber composite material is connected to the feed pipe, which is then introduced onto the aluminum foil on the bottom mold. After introduction, an electric closing mechanism seals the sides of the bottom mold. Then, the electric lifting frame lowers the top mold, bringing it into contact with the bottom mold, allowing the upper aluminum foil to adhere to the high-temperature liquid. This process lowers the plant fiber composite material located between the top and bottom molds. The process involves rapid cooling using built-in cooling devices in the top and bottom mold sections, which quickly solidifies the high-temperature liquid. After molding, the electric lifting frame is reset, opening the top and bottom mold sections. Because the cured plant fiber composite automotive interior parts are wrapped in aluminum foil at both the top and bottom, they can be quickly removed from between the top and bottom mold sections. The melting temperature of the aluminum foil, at over 600 degrees Celsius, is significantly higher than that of the cured plant fiber composite automotive interior parts, allowing for easy removal of the aluminum foil. The horizontal moving part on the starting side drives the aluminum foil holding moving part to move, guiding the aluminum foil on the upper and lower limit guide aluminum foil strips. Combined with the rotation of the aluminum foil roller and lower aluminum foil roller, the aluminum foil can be quickly replaced and bonded between the top and bottom mold sections, achieving efficient molding and demolding.

Detailed Implementation

[0046] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0047] like Figures 1-12 As shown in the figure, this embodiment provides an injection molding apparatus for processing plant fiber composite automotive interior parts, including a top mold and a bottom mold.

[0048] An electric lifting frame 3 is used for electric lifting adjustment between the top mold and the bottom mold.

[0049] Multiple sets of feed pipes are provided on the side of the bottom mold, and an electric closing part is provided inside the bottom mold that closes after being filled with plant fiber composite material;

[0050] Upper aluminum paper roller section and lower aluminum paper roller section are respectively provided on both sides of the top mold section and the side of the bottom mold section;

[0051] An upper limit guide aluminum paper strip 9 is installed on the outer side of the top mold section to guide the aluminum paper support of the upper aluminum paper roller section;

[0052] A lower limit guide aluminum paper strip 8 is installed on the outer side of the bottom mold part to guide the aluminum paper support of the lower aluminum paper roller part;

[0053] A side horizontal moving part is provided on the bottom mold part, which drives an aluminum paper pressing moving part. The aluminum paper pressing moving part is clamped between the upper limit guide aluminum paper strip 9 and the lower limit guide aluminum paper strip 8 to electrically guide the aluminum paper.

[0054] Overall working principle: The electric lifting frame 3 lowers the top mold, pressing the aluminum paper between the top and bottom molds. The aluminum paper is cut through contact between the top and bottom molds. Under the pressure of the top mold, the lower aluminum paper is pressed against the bottom of the bottom mold, while the upper aluminum paper adheres to the top of the top mold. The high-temperature liquid of the plant fiber composite material to be introduced is connected to the feed pipe. The high-temperature liquid is introduced through the feed pipe onto the aluminum paper on the bottom mold. After introduction, the electric closing mechanism seals the sides of the bottom mold. Then, the electric lifting frame 3 lowers the top mold, bringing it into contact with the bottom mold. This allows the upper aluminum paper to adhere to the high-temperature liquid, cooling the plant fiber composite material located between the top and bottom molds. The built-in cooling device provides rapid cooling, enabling the high-temperature liquid to solidify quickly. After molding, the electric lifting frame 3 is reset, opening the top and bottom mold sections. Since the solidified plant fiber composite automotive interior parts are wrapped in aluminum foil at both the top and bottom, they can be quickly removed from between the top and bottom mold sections. The melting temperature of the aluminum foil, at over 600 degrees Celsius, is significantly higher than that of the solidified plant fiber composite automotive interior parts, allowing the aluminum foil to be easily peeled off. The horizontal moving part on the starting side drives the aluminum foil holding moving part to move, guiding the aluminum foil on the upper limit guide aluminum foil strip 9 and the lower limit guide aluminum foil strip 8. Combined with the rotation of the aluminum foil roller and the lower aluminum foil roller, the aluminum foil is quickly replaced and bonded between the top and bottom mold sections, achieving efficient molding and demolding.
