Automobile door body guard plate injection mold facilitating demolding

Abstract

This invention discloses an injection mold for automotive door panel that facilitates demolding, relating to the field of automotive manufacturing molds. It includes a support plate, an mounting bracket mounted on the upper surface of the support plate, a slide block below the mounting bracket, and a vacuum pump mounted on the upper surface of the slide block. This invention uses an air pump to draw air and delivers it into the interior of the partition plate via an air outlet. The delivered gas pushes the molded product upwards along the inner wall of the bottom mold through vents, thus demolding. This demolding method reduces direct contact between the product and the mold, thereby lowering the risk of damage during demolding. The vacuum pump drives a suction cup to adsorb the product, ensuring its stability during demolding and avoiding displacement or tilting that can occur with traditional ejector pin demolding. Through gas propulsion and vacuum adsorption, it reduces bending, breakage, and scratches that can occur with traditional ejector pin demolding, improving the safety of the production process.

Description

Technical Field

[0001] This utility model relates to the field of automobile production molds, specifically an injection mold for automobile door panel that is easy to demold. Background Technology

[0002] As a crucial part of automobile manufacturing, the car door panel not only provides safety for drivers and passengers but also directly affects the overall aesthetics and comfort of the car. During the production process, the manufacturing quality of the car door panel directly impacts the car's quality and user experience. Currently, injection molds for car door panels commonly use ejector pins for demolding. While this method is simple, it has many drawbacks in practice. During demolding, the ejector pins are prone to bending or even breakage due to uneven forces and pressures. This not only leads to low demolding efficiency and affects production progress but also damages the mold, increasing maintenance costs. Furthermore, the ejector pins are easily scratched during demolding because they are in direct contact with the car door panel, which not only affects the appearance quality of the door panel but may also reduce its safety performance. Therefore, we provide an injection mold for car door panels that facilitates demolding to solve the above problems. Utility Model Content

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0022] The system includes a support plate 2, an mounting bracket 1 mounted on the upper surface of the support plate 2, a slide 6 located below the mounting bracket 1, a vacuum pump 7 mounted on the upper surface of the slide 6, a plurality of suction cups 8 mounted on the input end of the vacuum pump 7 after passing through the slide 6, a bottom mold 13 mounted on the upper surface of the support plate 2, an air pump 16 mounted on the bottom surface of the support plate 2, and two air outlet blocks 17 connected to the output end of the air pump 16 after passing through the support plate 2 and the bottom mold 13.

[0023] In this embodiment, an electric push rod 18 is installed on the inner bottom wall of the bottom mold 13, and a sealing block 19 is installed on the output end of the electric push rod 18. The electric push rod 18 drives the sealing block 19 to control the opening or closing of the vent hole 20, so as to prevent the material from seeping down during the shaping process.

[0024] In this embodiment, a partition 15 is installed on the inner wall of the bottom mold 13, and a vent hole 20 adapted to the sealing block 19 is opened on the outer surface of the partition 15.

[0025] In this embodiment, two electric slide rails B5 are installed on the outer surface of the support plate 2. The outer surfaces of the two electric slide rails B5 are slidably mounted with an electric slide rail A4. The outer surface of the slide block 6 is slidably mounted outside the electric slide rail A4. The electric slide rails B5 can drive the slide block 6 to flexibly adjust its height. The electric slide rail A4 can drive the slide block 6 to flexibly adjust its position.

[0026] In this embodiment, an electric lifting rod 11 is installed on the inner top wall of the mounting frame 1, and an extrusion plate 12 is installed at the output end of the electric lifting rod 11. The electric lifting rod 11 drives the extrusion plate 12 to apply pressure to the material inside the bottom mold 13, thereby helping the material to be shaped.

[0027] In this embodiment, a pump body 21 is mounted on the outer surface of the mounting bracket 1, and an input pipe 22 is connected to the input end of the pump body 21.

[0028] In this embodiment, the output end of the pump body 21 passes through the mounting bracket 1 and is connected to the connecting hose 10. The end of the connecting hose 10 away from the pump body 21 passes through the slide block 6 and is connected to the injection pipe 9. The pump body 21 drives the input pipe 22 to draw raw materials, which are then transported into the interior of the bottom mold 13 through the connecting hose 10 and the injection pipe 9, thus achieving precise delivery of raw materials.

[0029] In this embodiment, four support legs 14 are installed on the bottom surface of the support plate 2, and a controller 3 is installed on the outer surface of the support plate 2.

[0030] Working Principle: In use, first, place the device on the designated site using the support legs 14 to ensure stability. Then, start the pump body 21 via the controller 3, which drives the input pipe 22 to draw in the injection molding material. The molten plastic material is then transported to the bottom mold 13 via the connecting hose 10 and the injection pipe 9. Next, start the electric lifting rod 11, which drives the extrusion plate 12 to extrude and shape the material inside the bottom mold 13. After shaping, start the electric lifting rod 11 again to reset the extrusion plate 12. Then, start the electric slide rail B5 to adjust the height of the slide block 6. Next, start the electric slide rail A4 to move the slide block 6 and suction cup 8 directly above the bottom mold 13. Then... Air pump 16 draws air and delivers it to the interior of partition 15 via air outlet block 17. Then, electric push rod 18 is activated, which drives sealing block 19 to open vent hole 20. The gas is pushed upward along the inner wall of bottom mold 13 through vent hole 20 for demolding. During the upward demolding process, the product comes into contact with suction cup 8. At the same time, vacuum pump 7 is activated, which drives suction cup 8 to adsorb the product. Then, electric slide rail B5 is activated, which drives the product adsorbed by suction cup 8 to move out of bottom mold 13. Then, electric slide rail A4 drives the moved product to the lower material area. This realizes the injection molding, demolding and removal process, improving production efficiency and product quality.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
