Description
Technical Field
[0001] This utility model relates to the field of mold demolding structure technology, specifically a multi-angle slider auxiliary molding mechanism for automotive interior panel injection molds. Background Technology
[0002] Injection molds are precision tools used for the mass production of plastic parts. They inject molten plastic material into a pre-designed mold cavity, where it cools and solidifies to form a plastic product with specific shapes and dimensions. As a core tool in the plastics processing industry, the high precision of injection molds is crucial for producing plastic products with specific shapes and dimensions. This process not only determines the product's appearance quality and dimensional accuracy but also directly affects production efficiency. Therefore, in modern manufacturing, the design and manufacturing level of injection molds occupies an extremely critical position.
[0003] In the actual use of injection molds, the complex demolding process not only reduces the actual efficiency of the mold but may also negatively impact production speed and the quality of the final product. Furthermore, the cooling effect of the injection mold is equally crucial to product quality. Uneven cooling or insufficient cooling time can lead to problems such as product deformation, uneven shrinkage, and internal stress, severely affecting the product's appearance and dimensional accuracy.
[0004] Therefore, a multi-angle slider-assisted molding mechanism for automotive interior panel injection molds is needed to improve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a multi-angle slider-assisted molding mechanism for automotive interior panel injection molds, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A multi-angle slider-assisted molding mechanism for an automotive interior trim panel injection mold includes a moving mold, an upper mold on the base surface of the moving mold, an inner trim panel injection molded part embedded in the base surface of the moving mold, a demolding component installed on one side of the inner trim panel injection molded part and on the outer wall of the moving mold, a cooling component installed on one side of the demolding component and on the inner wall of the moving mold, an ejector rod installed on the inner wall of the moving mold, and an ejector block installed at one end of the ejector rod, wherein the ejector block is located directly below the inner trim panel injection molded part;
[0008] The demolding assembly includes a slider, which is mounted on the outer wall of the moving mold and located on one side of the inner protective plate injection molded part. A wear-resistant sheet is installed on the outer wall of the slider, and an inclined guide post is slidably connected to the outer wall of the slider, with one end of the inclined guide post mounted on the outer wall of the moving mold. A buffer spring is provided on the inner wall of the slider.
[0009] As a preferred embodiment of this utility model, the cooling component includes a cooling water pipe and an adjustable temperature control switch. The cooling water pipe is embedded in the inner wall of the moving mold, and an electrically controlled valve is installed on the outer wall of the cooling water pipe.
[0010] As a preferred embodiment of this utility model, a cooling pipe is installed at the outlet of the electrically controlled valve. One end of the cooling pipe is installed on the outer wall of the cooling water pipeline via a one-way valve. Multiple adjustable temperature control switches are provided and are located on the inner wall of the moving mold respectively.
[0011] As a preferred embodiment of this utility model, the inner cavity of the ejector rod is provided with a cooling water channel, the ejector rod is provided in multiple sets and is located on the inner wall of the moving mold respectively, the ejector block is embedded in the outer wall of the moving mold, and the connection between the ejector block and the moving mold is a sliding connection, and the demolding assembly is provided in multiple sets and is located on the outer wall of the moving mold respectively.
[0012] As a preferred embodiment of this utility model, the slider is provided in multiple sets and is located on the outer wall of the moving mold respectively. Two sets of sliders are designed to be perpendicular to the outer side of the moving mold, and the other two sets of sliders are at a 22-degree angle to the outer side of the moving mold. The buffer spring is located on one side of the inner protective plate injection molded part. The cooling water pipe has a rectangular structure. The electrically controlled valve is provided in multiple sets and is located on the outer wall of the cooling water pipe respectively.
[0013] As a preferred embodiment of this utility model, multiple sets of cooling pipes are provided and are respectively located on the inner wall of the moving mold, and the cooling pipes are located directly below the inner protective plate injection molded part. Multiple sets of one-way valves are provided and are respectively located on the outer wall of the cooling water pipe.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, the demolding component in the molding mechanism is assisted by a multi-angle slider of the automotive inner guard plate injection mold. When the slider moves upward along the inclined guide post, it disconnects and limits the inner guard plate injection part. When the mold is opened, the inner guard plate injection part is ejected simultaneously by the ejector block driven by other ejector rods. This helps to solve the problem that the complex demolding process not only reduces the actual efficiency of the mold, but also may have a negative impact on the production speed and the quality of the final product.
[0016] 2. In this utility model, the cooling component in the molding mechanism is assisted by a multi-angle slider of the automotive inner panel injection mold. When the set temperature is reached by the adjustable temperature control switch directly below the inner panel injection part, the adjustable temperature control switch will control the electric valve to open, thereby allowing the cooling water inside the cooling water pipe to flow into the inner cavity of the cooling pipe through the electric valve. This allows the cooling pipe to cool the inner panel injection part. Cooling will only begin when the temperature reaches the set value, and will stop when the temperature drops. This allows for zoned cooling based on the temperature of the inner panel injection part, which helps to solve problems such as uneven cooling or insufficient cooling time, which can lead to product deformation, uneven shrinkage, and internal stress.

[0029] The cooling water pipe 501 is embedded in the inner wall of the moving mold 1. An electrically controlled valve 503 is installed on the outer wall of the cooling water pipe 501.

One end of the cooling pipe 504 is connected to the outer wall of the cooling water pipe 501 via a one-way valve 505. Multiple adjustable temperature control switches 502 are provided and located on the inner wall of the moving mold 1. During injection molding, when the adjustable temperature control switch 502 located directly below the inner protective plate injection molded part 3 reaches the set temperature, it will...

This allows the cooling pipe 504 to cool the inner protective plate injection molded part 3. Cooling will only begin when the temperature reaches a certain value, and will stop when the temperature drops. This allows for zoned cooling based on the temperature of the inner protective plate injection molded part 3, which helps to solve problems such as uneven cooling or insufficient cooling time, which can lead to product deformation, uneven shrinkage, and internal stress.
