Description

Technical Field

[0001] This invention relates to the field of automotive interior parts manufacturing technology, specifically to an automotive interior parts molding equipment. Background Technology

[0002] Compression molding is an important production process for automotive interior parts. It utilizes the characteristics of each stage of the resin curing reaction to achieve product molding, namely, the molding material is plasticized, flows and fills the mold cavity, and the resin is cured and molded. It has advantages such as low raw material loss and small product warpage and deformation.

[0003] When producing automotive interior parts using compression molding equipment, corresponding molds are required. Before adding raw materials to the mold, a release agent is usually applied to the mold cavity to facilitate demolding after molding. Furthermore, after each molding process, residues and other impurities may remain inside the mold, requiring manual cleaning. These maintenance operations require staff assistance throughout the production process, resulting in low production efficiency for compression molding equipment. Therefore, a compression molding machine for automotive interior parts is needed to solve these problems. Summary of the Invention

The lower mold maintenance component 8 is used to clean the lower mold 6 and spray release agent. The lower mold maintenance component 8 includes a support plate 81, a horizontal slide groove 82, and a translation rod 83. The support plate 81 is mounted on both sides of the lower mold 6. The support plate 81 is provided with a horizontal slide groove 82. The two ends of the translation rod 83 are slidably connected in the horizontal slide groove 82. The blow-blowing box 11 and the liquid supply box 12 are mounted on the translation rod 83. The translation rod 83 can move horizontally above the lower mold 6 and drive the blow-blowing box 11 and the liquid supply box 12 to pass above the lower mold 6 to realize the blow-blowing cleaning and spraying of release agent.

[0031] The upper mold maintenance component 9 is installed on the lower mold maintenance component 8. The upper mold maintenance component 9 can move horizontally and move synchronously with the upper mold 7. The upper mold maintenance component 9 is used to clean the upper mold 7 and spray a release agent. The upper mold maintenance component 9 includes a lifting rod 91, a horizontal connecting rod 92, and an inclined slide groove 93. The translation rod 83 has through slots at both ends, and the lifting rod 91 is vertically slidably connected to the through slots at both ends of the translation rod 83. The support plate 81 also has an inclined slide groove 93. A sliding column 94 is connected to the lower side of the lifting rod 91 and is slidably connected to the inclined slide groove 93. The upper end of the lifting rod 91 is connected to the horizontal connecting rod 92. The spray box 11 and the liquid supply box 12 are installed on the horizontal connecting rod 92. The movement of the lower mold maintenance component 8 can drive the upper mold maintenance component 9 to move synchronously, and the upper mold maintenance component 9 can move horizontally and move synchronously with the upper mold 7, ensuring the maintenance effect on the upper mold 7.

[0032] Both the lower mold maintenance assembly 8 and the upper mold maintenance assembly 9 are equipped with a blower box 11 and a liquid supply box 12. The air outlet of the blower box 11 is a flat strip structure, which facilitates increasing air pressure and improving the cleaning effect. The liquid supply box 12 has atomizing nozzles 13 distributed in a straight line at equal intervals, which can evenly spray the release agent onto the mold surface. The company's public air source is connected to the blower box 11 through a solenoid valve, and the liquid supply box 12 is connected to a booster pump and a liquid storage tank to realize the supply of release agent.

[0033] The drive assembly 10 converts the power of the lifting seat 4 into the driving force of the lower mold maintenance assembly 8 and the upper mold maintenance assembly 9.

[0034] The working process of this invention is as follows:

[0035] When producing automotive interior parts, the corresponding product mold is installed on the molding equipment, raw materials are added to the lower mold 6, the hydraulic cylinder 5 is started to drive the lifting seat 4 to move downward, and the lifting seat 4 drives the upper mold 7 to move synchronously and close with the lower mold 6, so as to realize the molding production of automotive interior parts.

[0036] After molding, the lifting seat 4 raises the upper mold 7 to a certain height, causing the upper mold 7 to separate from the lower mold 6. At this time, the translation rod 83 and the transverse connecting rod 92 are located on one side of the mold. After the product is removed, the lifting seat 4 continues to move upward. The lifting seat 4 drives the translation rod 83 to slide horizontally through the connecting seat 101 and the connecting rod 103. Under the action of the inclined slide groove 93 and the sliding column 94, the translation rod 83 drives the lifting rod 91 to slide upward, so that the spray box 11 and the liquid supply box 12 on the transverse connecting rod 92 always maintain a suitable working distance from the upper mold 7.

[0037] High-pressure gas is supplied to the blow box 11 to clean the mold cavity by blowing, and release agent is supplied to the liquid supply box 12. The release agent is atomized by the atomizing nozzle 13 and sprayed evenly into the mold cavity, realizing automatic maintenance of the mold before each molding process.
