DETAILED DESCRIPTION

[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0021] Example

[0022] See also Figure 1-3 , the utility model provides a technical solution: a demoulding structure;

[0023] This case aims to provide a structure that is conducive to the demoulding and ejection of molded products inside the mold. The existing ejection structure has a low degree of automation and requires operators to manually reset it after operation;

[0024] Based on the above problems, the components in this case include a main body 1, a base 2, a lower die base 3, an upper die base 4 and a hydraulic push rod 5. The base 2 is installed on the lower side of the main body 1, the lower die base 3 is arranged on the top of the base 2, the driving end of the hydraulic push rod 5 is connected to the upper side of the main body 1, and the output end of the hydraulic push rod 5 is connected to the top of the upper die base 4. An ejection assembly is arranged inside the base 2 and the lower die base 3, and the ejection assembly includes:

[0025] A double-axis motor 6, two connecting shafts 7, two transmission blocks 8, a lifting plate 9, two connecting blocks 10, a plurality of return springs 11, two ejection racks 12 and a discharge part;

[0026] The dual-axis motor 6 is installed inside the base 2, one end of the two connecting shafts 7 is connected to the driving end of the dual-axis motor 6, and the other end penetrates the wall of the base 2 and is connected to the two transmission blocks 8, one end of the two connecting blocks 10 penetrates the wall of the base 2 and is connected to the two sides of the lifting plate 9, one end of a plurality of return springs 11 is connected to the bottom inner wall of the base 2, and the other end is connected to the bottom of the lifting plate 9, the bottom of the two ejection frames 12 penetrates the bottom wall of the lower die base 3 and the top wall of the base 2 and is connected to the top of the lifting plate 9, and the discharge part is installed on one side of the base 2;

[0027] The material discharging part includes: a support platform 13, an electric push rod 14, a push plate 15 and a material guide plate 16;

[0028] The support platform 13 is installed on the lower side of the main body 1, the driving end of the electric push rod 14 is connected to the top of the support platform 13, one side of the push plate 15 is connected to the output end of the electric push rod 14, and the guide plate 16 is installed on one side of the lower die base 3;

[0029] It should be noted that during use, first, the die-casting operation can be carried out through the cooperation of the upper die base 4, the lower die base 3, and the hydraulic push rod 5. After the die-casting is completed, the upper die base 4 is separated from the lower die base 3. At this time, the double-axis motor 6 runs, and drives the two elliptical transmission blocks 8 to transmit 90° through the two connecting shafts 7. At this time, the two transmission blocks 8 will drive the lifting plate 9 to rise through the two connecting blocks 10, and stretch a number of reset springs 11, and can drive the ejector frame 12 to rise and eject the product. At this time, the lower edge of the product will be aligned with the upper edge of the lower die base 3. At the same time, the electric push rod 14 on the top of the support platform 13 runs, and the product can be pushed out from the upper side of the lower die base 3 through the electric push rod 14 and the push rod, and slide along the guide plate 16, and finally complete the automatic ejection and unloading operation of the die-casting product;

[0030] It should be emphasized that the dual-axis motor 6 is a motor structure composed of two motors, which consists of two rotors and a stator. When the dual-axis motor 6 is running and the ejector frame 12 is raised, the electric push rod 14 is synchronously operated and can push out the die-cast product. Then the electric push rod 14 drives the push plate 15 to reset. At this time, the dual-axis motor 6 is synchronously reset, and with the help of a number of reset springs 11, the lifting plate 9 can be quickly reset, and the ejector frame 12 can be retracted into the lower die base 3 to achieve automatic reset.

[0031] Since the lifting plate 9 moves downward after being reset, it may squeeze the top of the dual-axis motor 6. Therefore, a groove is provided at the bottom of the lifting plate 9 to prevent the lifting plate 9 from causing damage to the dual-axis motor 6.

[0032] Four guide rods 17 are arranged between the upper side of the main body 1 and the base 2, and the two sides of the upper die base 4 are slidably connected with the four guide rods 17, which can increase the stability of the upper die base 4 during movement;

[0033] A notch is provided at the bottom of the support platform 13. Both transmission blocks 8 are set to be elliptical. The support platform 13 is provided with a notch corresponding to the position of the transmission block 8 to prevent the support platform 13 from affecting the movement of the transmission block 8.

[0034] The two ejector frames 12 are both T-shaped, and the lower die base 3 is provided with limiting grooves corresponding to the ejector frames 12 to limit the positions of the ejector frames 12 .

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