Specific implementation mode

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1:

[0020] Please refer to Figures 1-3 , an anti-warping injection mold for an automotive passenger-side instrument panel, comprising a bottom plate 1, a lower mold 2 fixedly installed on the upper surface of the bottom plate 1, a slide post 3 fixedly installed on the upper surface of the bottom plate 1, a slider 4 movably connected to the outer surface of the slide post 3, an upper mold 5 fixedly installed on the adjacent surface of the slider 4, a top plate 6 fixedly installed at the upper end of the slide post 3, an air collecting box 7 fixedly installed on the upper surface of the top plate 6, an air cooler 8 fixedly installed on the upper surface of the air collecting box 7, a suction fan 9 fixedly installed on the upper surface of the top plate 6, a pumping device 10 fixedly installed on the rear surface of the air collecting box 7, a conveying pipe 11 fixedly installed on the outer surface of the pumping device 10, a baffle 12 fixedly installed on the lower surface of the upper mold 5, and a groove 13 opened on the upper surface of the lower mold 2.

[0021] Specifically: During the use of the present utility model, when injection molding is required, first, an anti-corrosion material is applied to the inside of the mold cavities of the upper mold 5 and the lower mold 2 to prevent warping caused by corrosion. At this time, the controller 20 controls the hydraulic rod to start, driving the upper mold 5 to move downward until the upper mold 5 is completely fitted with the lower mold 2. Then, the injection molding principle is input into the upper mold 5 and the lower mold 2 through the material barrel 14 and the feeding pipe 19. When the input is completely finished and cooling is required, the suction fan 9 starts to extract external gas into the inside of the air collection box 7. When the external gas enters the inside of the air collection box 7, the air cooler 8 starts to cool the gas inside the air collection box 7. After cooling is completed, the pumping device 10 starts to pump the cooled gas inside the air collection box 7 through the conveying pipe 11 into the upper mold 5 and the lower mold 2. The cold air inside the upper mold 5 and the lower mold 2 cools the injection-molded sub-instrument panel inside the upper mold 5 and the lower mold 2. After cooling is completed, the suction fan 9 sucks out the internal gas again and finally discharges it outdoors.

[0022] In this implementation scheme: A controller 20 is fixedly installed on the upper surface of the bottom plate 1. Mold cavities are provided on the corresponding surfaces of the upper mold 5 and the lower mold 2. The air cooler 8 communicates with the inside of the air collection box 7. The suction fan 9 communicates with the inside of the air collection box 7. The inside of the pumping device 10 communicates with the inside of the air collection box 7. The inside of the conveying pipe 11 communicates with the inside of the pumping device 10. The inside of the upper mold 5 and the lower mold 2 is a cavity structure.

[0023] Specifically: The cavity structure facilitates the direct and large-area contact of the cold air with the sub-instrument panel, thereby achieving the effect of quickly cooling it. The shape of the mold cavity is consistent with the shape of the sub-instrument panel required for production.

[0024] In this implementation scheme: A hydraulic rod is fixedly installed on the lower surface of the top plate 6. The lower end of the hydraulic rod is fixedly connected to the upper end of the upper mold 5. The conveying pipe 11 is made of soft leather material. The size of the baffle 12 matches the size of the groove 13.

[0025] Specifically: The soft leather material facilitates the movement of the upper mold 5. The design of the baffle 12 and the groove 13 can limit the upper mold 5 and the lower mold 2, thereby ensuring the accuracy of their docking and thus ensuring the production quality.

[0026] In this implementation scheme: The controller 20 is electrically connected to the servo motor 15, the telescopic rod 16, the suction fan 9, the pumping device 10, the air cooler 8, and the hydraulic rod.

[0027] Working principle: Through the cooperative setting of the air cooler 8 and the suction fan 9, this design can achieve the effect of conveying cold air into the upper mold 5 and the lower mold 2, thereby accelerating the cooling of the sub-instrument panel and enabling it to cool quickly. Compared with the related technology, a warpage-proof injection mold for an automotive sub-instrument panel provided by the present utility model has the following beneficial effects: This design can achieve the effect of quickly cooling the production of the sub-instrument panel, thereby improving the cooling efficiency and avoiding the warpage phenomenon at the edge of the sub-instrument panel caused by external forces, which affects the quality.

[0028] Embodiment 2:

[0029] Please refer to Figures 1-3 , a material bucket 14 is fixedly installed on the upper surface of the top plate 6, a servo motor 15 is fixedly installed on the upper surface of the material bucket 14, a telescopic rod 16 is movably installed on the upper inner wall of the material bucket 14, a pressing plate 17 is fixedly installed at the lower end of the telescopic rod 16, a stirring rod 18 is fixedly installed on the lower surface of the pressing plate 17, and a material conveying pipe 19 is fixedly installed on the lower surface of the top plate 6.

[0030] Specifically: When the material is inside the material bucket 14, at this time, the servo motor 15 is started, which drives the telescopic rod 16 to rotate. The telescopic rod 16 rotates, driving the pressing plate 17 and the lower stirring rod 18 to rotate. When the stirring rod 18 rotates, it stirs the material inside the material bucket 14 to prevent it from solidifying. When feeding is required, the telescopic rod 16 is started at this time, driving the pressing plate 17 to move downward. The pressing plate 17 moves downward, and the material inside the material bucket 14 is discharged from the material conveying pipe 19 by pressurization. Through continuous pressurization, the material can fully enter every part of the mold cavity to ensure the integrity of its production.

[0031] In this implementation scheme: The outer surface of the pressing plate 17 is movably connected to the inner wall of the material bucket 14. The material conveying pipe 19 is made of soft leather and high-temperature resistant material. The inside of the material bucket 14 is interconnected with the inside of the upper mold 5 through the material conveying pipe 19.

[0032] Specifically: The pressing plate 17 is movably connected to the inner wall of the material bucket 14. In this way, during the downward movement of the pressing plate 17, it can scrape the inner wall of the material bucket 14 to avoid excessive adhesion of the material to the inside of the material bucket 14. The high-temperature resistant soft leather material facilitates the movement of the upper mold 5 and the conveying of the material.

[0033] Working principle: This design can stir the materials inside the material barrel 14 in the form of a stirring rod 18 in real time, thus preventing them from solidifying. In the form of a pressing plate 17 of a telescopic rod 16, the effect of pressurizing the discharging of the material barrel 14 is achieved, so that the feeding is faster while ensuring that the materials enter every corner of the mold cavity, guaranteeing the production quality. Compared with the related technologies, a warpage-proof injection mold for an automotive passenger-side instrument panel provided by the present utility model has the following beneficial effects: This design can stir the materials and pressurize the feeding of the materials at the same time, thus avoiding the situation that the materials cannot be used due to solidification and the slow feeding rate of the materials, resulting in insufficient entry of the materials into the mold cavity, which affects the production quality.

[0034] The controller 20 is of an existing structure, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common general knowledge in the art. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0035] For the selection of each device in the above-mentioned use of the equipment, different selections are made according to the actual situation, and various parameters are referred to, and the functions of the used equipment are corresponding to the achieved effects.

[0036] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
