[0002] Automatic mold ejection mechanisms are commonly used in production processes such as injection molding, die casting, or stamping. Their core function is to safely and undamagedly eject cooled plastic products from the mold using mechanical devices, thereby improving efficiency and reducing human intervention.

[0003] Traditional demolding methods are divided into manual demolding and mechanical demolding. Manual demolding is inefficient, relies on manual labor, and is prone to damaging the product. Traditional mechanical demolding mechanisms require multiple components to achieve ejection and resetting, resulting in complex structures and difficult assembly, while also increasing the manufacturing cost of the mold. Furthermore, thin-walled or sticky materials may stick to the inner wall of the mold during demolding, causing product deformation. This paper proposes an improvement to address these issues.

[0023] It should be noted that by attaching a spring 5 to the outer wall of the support column 4, the demolding template 9 can quickly return to its original shape after being squeezed downwards, thus enabling the next work process. This semi-automatic demolding mechanism greatly reduces the number of work processes, improves work efficiency, and reduces labor costs. Furthermore, by controlling the hydraulic pump 22 through the control button 21, the telescopic rod 24 drives the demolding template 9.

[0024] In a preferred embodiment, a piston rod 18 is slidably connected to the inner cavity of the square groove 16, a hydraulic pump 20 is installed on the top of the piston rod 18, an air guide pipe 17 is connected to the side of the inner cavity of the square groove 16, an air pump 19 is connected to the tail of the air guide pipe 17, and the air pump 19 is located on the top of the top plate 14.

[0025] It should be noted that by connecting the air guide pipe 17 to the inner side of the square groove 16, the device can evacuate air through the air guide pipe 17 before ejection, thereby vacuum adsorbing and fixing the product. When ejecting, it switches to ventilation to avoid the product shifting or tearing due to the stickiness of the material. In addition, the inner cavity of the square groove 16 is slidably connected to the piston rod 18, so that the device can block the square groove 16 under normal conditions to prevent dirt from entering the inside of the square groove 16 and blocking the air guide pipe 17.

[0026] In a preferred embodiment, there are four support columns 4, which are located at the four corners of the partition plate 2 respectively. The position of the first circular groove 3 corresponds to the position of the second circular groove 6, and the support columns 4 slide on the inner wall of the second circular groove 6.

[0027] It should be noted that by setting four support columns 4, the device can be stably supported, avoiding the collapse of the entire device due to uneven force during operation. Furthermore, by sliding between the support columns 4 and the inner wall of the circular groove 6, the demolding template 9 can move up and down, so that the mold can be removed from the demolding groove 11 simply by moving it downwards during demolding, which facilitates the removal of the mold.

[0028] In a preferred embodiment, the boss 7 slides on the inner wall of the third circular groove 12, the support plate 8 is located inside the first demolding groove 11, the size of the support plate 8 corresponds to the size of the first demolding groove 11, the size of the first demolding groove 11 corresponds to the size of the second demolding groove 15, the position and size of the fourth circular groove 13 correspond to the position and size of the second circular groove 6, the support column 4 slides on the inner wall of the fourth circular groove 13, and there are two support plates 10, which are located on both sides of the demolding template 9.

[0029] It should be noted that by sliding the boss 7 inside the circular groove three 12, when demolding, the boss 7 can eject the mold, avoiding the situation where the mold gets stuck in the demolding groove. At the same time, since the size of the support plate 8 is the same as that of the first demolding groove 11, when the boss 7 ejects the support plate 8, it can also eject the mold stored in the first demolding groove 11, greatly increasing the convenience of the device. And since the position and size of the first demolding groove 11 are the same as those of the second demolding groove 15, the two demolding grooves can tightly clamp the mold, avoiding misalignment caused by the loosening of the mold, which affects the product quality.

[0030] In a preferred embodiment, the shape of the top plate 14 is "convex" - shaped. There are two telescopic rods 24, and the two telescopic rods 24 are respectively located on both sides of the bottom of the top plate 14. The bottom of the telescopic rod 24 is connected to the support plate 10. There are two liquid - guiding pipes 23, and the two liquid - guiding pipes 23 are respectively located on both sides of the outer wall of the second hydraulic pump 22. The second hydraulic pump 22 is hydraulically connected to the telescopic rod 24 through the liquid - guiding pipe 23.

[0031] It should be noted that by providing two telescopic rods 24, when demolding, the telescopic rods 24 can press down the demolding plate 9, so that the mold inside the first demolding groove 11 can be exposed. And by connecting the second hydraulic pump 22 and the telescopic rod 24 through the liquid - guiding pipe 23, the force of the telescopic rod 24 during demolding can be controlled, avoiding the situation that the mold cannot be completely ejected due to too small force or the mold being damaged due to too large force, increasing the practicality of the device.

[0032] In a preferred embodiment, both the first hydraulic pump 20 and the second hydraulic pump 22 are electrically connected to the control button 21, and the air pump 19 is electrically connected to the control button 21.

[0033] It should be noted that through the electrical connection between the air pump 19 and the control button 21, when demolding the mold, the air pump 19 can supply air, so that the product can be vacuum - adsorbed and fixed before ejection, and then switched to blowing when ejecting, avoiding product deviation or tearing caused by material viscosity. At the same time, on the basis of traditional mechanical ejection, pneumatic drive is integrated to achieve staged ejection force control.

[0034] Working principle: When using this equipment, firstly, the control button 21 drives the hydraulic pump 22, which then drives the telescopic rod 24, causing the top plate 14 to tightly close with the demolding plate 9. This forms the demolding groove 11 and demolding groove 25, creating a molded cavity. Material is then injected into the cavity for molding. After the mold is formed, the control button 21 is used to start the hydraulic pump 20 and the air pump 19. The hydraulic pump 20 drives the piston rod 18, causing it to move upwards and expose the air guide pipe 17. At this time, the air guide pipe 17 begins to extract gas. This creates a vacuum inside the cavity, which helps to adhere the mold and prevent it from shifting. Then, by operating the control button 21, the hydraulic pump 22 and the air pump 19 are started. The air pump 19 sprays high-pressure gas to reduce the adhesion between the product and the cavity, preventing the mold from sticking to the inner wall of the demolding groove 15. The hydraulic pump 22 drives the telescopic rod 24, which presses the demolding plate 9 downward, causing it to slide downward. At the same time, the support plate 8, supported by the boss 7, pushes the mold out from inside the demolding groove 11, thus completing the entire demolding process.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
