DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0019] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] Combined with attachment Figures 1 to 4As shown, this embodiment discloses an automatic demolding structure for an elevator mold, comprising a fixed mold and a movable mold. The fixed mold comprises an upper doubler plate, a fixed mold frame 2, an upper cavity mold 6, and an inclined guide column 11. The fixed mold frame 2 is fixedly connected to the upper doubler plate 1, and the upper cavity mold 6 is fixed in the fixed mold frame 2. The upper ends of the inclined guide columns 11 are fixedly connected to the fixed mold frame 2. The movable mold comprises a lower doubler plate 5, a mold foot 4, a movable mold frame 3, a lower cavity mold 7, a pair of sliders 10, and two undercut blocks 8. The movable mold frame 3 is fixed to the mold foot 4, which is fixed to the lower doubler plate 5. The lower cavity mold 7 is fixed in the movable mold frame 3. The sliders 10 are provided on both sides of the lower cavity mold 7. The inclined guide columns 11 are slidably connected to the sliders 10. The sliders 10 are provided with inclined holes, and the inclined guide columns 11 penetrate into the inclined holes. The rear end of the undercut block 8 is fixed to the fixed mold frame 2 by screws 13, and the front end of the undercut block 8 extends into the product cavity from the side of the product cavity. There is an undercut block 8 at each end of the product cavity. The upper cavity mold 6, the lower cavity mold 7, the undercut block 8 and the slider 10 constitute the product cavity.

[0021] The lower front end of the undercut block 8 is provided with an inclined surface 14. When the mold is closed, the lower side of the inclined surface 14 contacts the slider 10. When demolding, the slider 10 moves to the sides and separates from the inclined surface 14. When the robot grips the runner rod, the product can be lifted a little more, preventing the base of the lower part of the product 9 from hitting the undercut block 8 and causing damage to the product, thereby avoiding the mold collision phenomenon.

[0022] An ejector plate 15 is provided above the lower composite plate 5 , and an ejector 12 is provided on the ejector plate 15 . The ejector 12 passes through the movable mold frame 3 and the lower cavity mold 7 and extends into the lower part of the product cavity. An ejection hole 16 is provided on the lower composite plate 5 .

[0023] After the injection molding is completed, under the driving force of the injection molding machine, the movable mold and the fixed mold are separated, and the slider 10 moves outward under the driving force of the inclined guide column 11, and the ejector plate 15 drives the ejector 11 to eject the product through the ejection hole 16 of the injection molding machine. At this time, the undercut block 8 is still in contact with the product, and then the runner rod is clamped by the robot. There is a product 9 connected to each end of the runner rod. Since the runner rod is still soft after injection molding, it will be deformed when the robot is clamped. The products at both ends of the runner rod will shrink inward and separate from the undercut block 8. Finally, the robot takes out the product, and then closes the mold to enter the next cycle. The entire demoulding process is fully automated, which can effectively improve production efficiency and solve the problem that ordinary elevator molds cannot be demoulded.

[0024] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent change or modification made to the above embodiment based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
