The elastic extrusion mechanism includes a moving rod 2 arranged in the installation groove 1. Two extrusion rods 3 are fixedly connected to the top of the moving rod 2. The tops of both extrusion rods 3 extend into the lower mold 103. The extrusion rods 3 are used to extrude and eject the product from the lower mold 103. The lower mold 103 is hermetically sleeved on both extrusion rods 3. Two movable perforations 14 are formed in the bottom inner wall of the lower mold 103. The outer side of the extrusion rod 3 is adhesively coated with a first sealing rubber sheet. The outer side of the first sealing rubber sheet is in movable contact with the outer side of the corresponding movable perforation 14.

The inner wall of the first rectangular perforation is in movable contact with the corresponding first sealing rubber sheet. The first rectangular perforation is used for the corresponding extrusion rod 3 to pass through. A plurality of first springs 4 are fixedly connected between the top of the moving rod 2 and the top inner wall of the installation groove 1. A plurality of grooves are formed in the top inner wall of the installation groove 1. The top inner wall of the groove is fixedly connected to the top of the corresponding first spring 4.

When the top of the extrusion rod 3 is flush with the bottom inner wall of the lower mold 103, the bottom of the moving plate 7 is in movable contact with the top of the lower mold 103;

[0024] An elastic limiting mechanism is installed on the upper die 102. The top of the elastic limiting mechanism extends above the moving plate 7. Two vertical rods 12 are fixedly connected to the bottom of the top plate 101. The bottom ends of the two vertical rods 12 are in movable contact with the top of the elastic limiting mechanism. The elastic limiting mechanism includes two push blocks 9. The upper die 102 is hermetically and movably sleeved on the two push blocks 9. Wherein, two movable grooves are formed in the bottom of the upper die 102. The outer side of the push block 9 is adhesively coated with a second sealing rubber sheet. The outer side of the second sealing rubber sheet is in movable contact with the inner wall of the corresponding movable groove.

Wherein, a first through hole is formed in the top inner wall of the movable groove, and two second through holes are formed in the top of the moving plate 7. The inner walls of the first through hole and the second through hole are both in movable contact with the outer side of the corresponding positioning rod 10. The first through hole and the second through hole are both used for the corresponding positioning rod 10 to pass through. The moving ring 11 is sleeved on the outer side of the output shaft of the electric telescopic rod 15. The inner wall of the moving ring 11 is not in contact with the outer side of the output shaft of the electric telescopic rod 15. Two second springs 13 are fixedly connected between the bottom of the moving ring 11 and the top of the moving plate 7. The second springs 13 are movably sleeved on the corresponding positioning rods 10. The top of the moving ring 11 is in movable contact with the bottom ends of the two vertical rods 12. The second spring 13 is used to support the positioning rod 10, the moving ring 11 and the push block 9. By using its telescopic elasticity, when the moving ring 11 contacts the vertical rod 12, a spatial distance for the moving plate 7 to continue moving upward can be provided; through the setting of a series of structures of the present utility model, during the process of lifting the upper die 102 after the product is die-cast and formed, by means of bottom extrusion and ejection in cooperation with top limiting extrusion, the formed product can be quickly separated from the lower die 103 and the upper die 102, so that the demoulding operation of the formed product can be quickly completed without the need for personnel to use tools, thereby improving the demoulding efficiency.

[0025] Working principle: When in use and during die-casting molding, the electric telescopic rod 15 is started forward. The output shaft of the electric telescopic rod 15 drives the moving plate 7 to move downward. The moving plate 7 drives the two extrusion blocks 8 to move downward. When the bottom of the extrusion block 8 contacts the top of the corresponding guide rod 5, the continuously moving extrusion block 8 extrudes the corresponding guide rod 5. Under the extrusion force, the guide rod 5 moves downward accordingly. The two guide rods 5 drive the moving rod 2 to move downward simultaneously and stretch the first spring 4. The moving rod 2 drives the two extrusion rods 3 to move downward. Since when the extrusion block 8 contacts the corresponding guide rod 5, the distance between the top of the extrusion rod 3 and the bottom inner wall of the lower mold 103 is the same as the distance between the bottom of the moving plate 7 and the top of the lower mold 103. When the top of the extrusion rod 3 is flush with the bottom inner wall of the lower mold 103, the bottom of the moving plate 7 is in movable contact with the top of the lower mold 103. At this time, the moving plate 7 drives the upper mold 102 to move into the lower mold 103 for die-casting molding operation;

[0026] After the die-casting molding cools down, the electric telescopic rod 15 is started in reverse, so that the moving plate 7 drives the two extrusion blocks 8 to change to move upward. While the extrusion block 8 moves upward, it relaxes the extrusion force on the corresponding guide rod 5. At this time, the elastic force of the first spring 4 in the stretched state drives the two extrusion rods 3 to move upward through the moving rod 2. While the two extrusion rods 3 move upward, they push the molded product inside the lower mold 103 upward, so as to automatically push out the molded product from the inside of the lower mold 103 during the process of lifting the upper mold 102 after die-casting molding, completing the demolding. There is no need for personnel to use tools for demolding, improving the demolding efficiency;

[0027] If the molded product adheres to the bottom of the upper mold 102, when the moving plate 7 drives the moving ring 11 to contact the bottom ends of the two vertical rods 12 through the two second springs 13, the movement of the moving ring 11 is restricted. At this time, the continuously moving upward moving plate 7 drives the upper mold 102 to move upward. Since the moving ring 11 is restricted from moving upward at this time, the push block 9 connected to the moving ring 11 through the positioning rod 10 is restricted from moving upward. The continuously moving upward moving plate 7 compresses the two second springs 13 upward. At this time, the push block 9 restricts the molded product adhering to the bottom of the upper mold 102 from moving upward, so that the continuously moving upward upper mold 102 is separated from the bottom of the molded product, thus completing the demolding operation of the molded product from the upper mold 102. This method of demolding the molded product from the upper mold 102 still does not require personnel to use tools for operation, further improving the demolding efficiency;

[0028] After demoulding, the product can be directly removed. Immediately afterwards, the electric telescopic rod 15 is started in the forward direction, causing the moving plate 7 to move downward to reset. While the moving plate 7 moves downward, the compression force on the two second springs 13 is released, causing the two second springs 13 to gradually reset. After resetting, the electric telescopic rod 15 can be stopped and wait for the next die-casting operation.

[0029] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
