[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a die-casting mold ejection mechanism for a metal parts die-casting machine, such as... Figure 1-4 As shown, the die casting mold ejection mechanism of the metal parts die casting machine includes a die casting machine base 1, a mounting seat 2 fixedly installed on the upper side of the die casting machine base 1, support columns 3 fixedly installed at the corners of the mounting seat 2, a top seat 4 provided at the upper end of the four sets of support columns 3, a mounting cavity 5 provided inside the mounting seat 2, a top plate 6 movably installed inside the mounting cavity 5, four sets of connecting columns 7 fixedly installed at the lower end of the top plate 6, a connecting plate 8 fixedly installed at the lower end of the four sets of connecting columns 7, a fixed mold 9 fixedly installed on the upper side of the mounting seat 2, a die casting groove 10 provided in the fixed mold 9, a tensioning assembly provided between the connecting plate 8 and the top seat 4, and a push-pull assembly for unloading metal parts provided on the front side of the top seat 4.

[0029] During use, after the die-casting mold completes the die-casting operation, the top seat 4 drives the top plate 6, four sets of connecting columns 7 and connecting plate 8 to rise through the tensioning component, thereby ejecting the die-cast metal parts. At the same time, the push-pull component moves synchronously, thereby discharging the ejected metal parts and realizing the unloading operation of the metal parts.

[0030] The tensioning assembly includes four sets of connecting rods 11 and four sets of connecting sleeves 12. The four sets of connecting rods 11 are fixedly installed on the upper side of the connecting plate 8, and the four sets of connecting sleeves 12 are fixedly installed on the lower side of the top seat 4. Each of the four sets of connecting sleeves 12 has a movable groove 13, and each of the four sets of movable grooves 13 has a first return spring 14 installed in it. The upper ends of the four sets of connecting rods 11 are movably inserted into the four sets of movable grooves 13.

[0031] During the ejection process, the top seat 4 rises, driving the four sets of connecting sleeves 12. As the four sets of connecting sleeves 12 rise, the four sets of connecting rods 11 in the four sets of movable slots 13 slide out under the restoring force of the four sets of first return springs 14. The top seat 4 continues to rise, pulling the four sets of connecting sleeves 12 and the four sets of connecting rods 11 upward, thereby driving the top plate 6 to eject the die-cast metal parts.

[0032] The protrusion on the upper side of the top plate 6 is inserted into the die-casting groove 10, and the height of the protrusion on the upper side of the top plate 6 is the same as the height of the inner wall of the die-casting groove 10.

[0033] During the upward ejection of the top plate 6, the height of the protrusion on the upper side of the top plate 6 is the same as the height of the inner wall of the die casting groove 10. The protrusion will slide inside the die casting groove 10, and the upper side of the protrusion can be flush with the upper opening of the die casting groove 10. This design makes the top plate 6 more stable when ejecting metal parts, and can completely eject the die-cast metal parts.

[0034] The outer diameter of the protrusion on the upper side of the top plate 6 is the same as the inner diameter of the die-casting groove 10, and the protrusion on the upper side of the top plate 6 is adapted to the inner wall of the die-casting groove 10.

[0035] This design ensures smoother sliding of the top plate 6 within the die-casting tank 10, reducing friction and resistance and improving the operating efficiency of the ejection mechanism. At the same time, the tight fit between the protrusion and the inner wall of the die-casting tank 10 enhances the stability of the ejection mechanism, preventing possible shaking or displacement during ejection, thus ensuring that the metal parts can be accurately ejected.

[0036] The push-pull assembly includes a mounting plate 15, which is fixedly installed on the front side of the mounting base 2. Two sets of guide sleeves 16 are fixedly installed on the upper rear side of the mounting plate 15. Push rods 17 are movably inserted into the two sets of guide sleeves 16. Connecting seats 18 are fixedly installed at the front ends of the two sets of push rods 17. Rotating rods 19 are rotatably installed on the upper side of the two sets of connecting seats 18. The two sets of rotating rods 19 are rotatably connected to the front end of the top seat 4. Push plates 21 are fixedly installed at the front ends of the two sets of push rods 17.

[0037] When the top seat 4 rises, the rotation of the two sets of rotating rods 19 causes the two sets of connecting seats 18 to drive the two sets of push rods 17 to slide forward within the two sets of guide sleeves 16, thereby driving the push plate 21 to move forward and push out the die-cast metal parts, thus realizing the unloading operation of the metal parts.

[0038] A second return spring 20 is sleeved on the push rod 17 between the guide sleeve 16 and the two connecting seats 18.

[0039] When the top seat 4 descends, under the restoring force of the second return spring 20, the two sets of push rods 17 and push plate 21 are reset, preparing for the next metal part ejection operation.

[0040] An inclined guide plate 22 is provided at the rear end of the fixed mold 9. The inclined guide plate 22 is inclined and the rear end of the inclined guide plate 22 is lower than the front end of the inclined guide plate 22.

[0041] This design allows metal parts to slide smoothly along the inclined surface of the inclined guide plate 22 when they are ejected, avoiding the accumulation or jamming of metal parts at the rear end of the fixed mold 9, thereby improving the material feeding efficiency of metal parts. At the same time, the inclined guide plate 22 can also guide the falling direction of metal parts, so that the metal parts can fall more accurately into the predetermined collection position, further improving production efficiency.

[0042] The lower sides of the mounting plate 15 and the push plate 21 are on the same plane as the upper side of the fixed mold 9, and the lower side of the push plate 21 is flush with the upper side of the fixed mold 9.

[0043] This design ensures that the ejector plate 21 can slide smoothly over the fixed mold 9 when the metal part is ejected, without any obstruction, thus guaranteeing a smooth ejection operation. At the same time, this planar design also helps to reduce friction and resistance during the ejection process, further improving ejection efficiency.

[0044] The rear end of the push plate 21 is U-shaped, and the rear sides of the two ends of the right end of the push plate 21 protrude from the rear side of the middle part of the push plate 21.

[0045] This makes the push plate 21 more stable when pushing metal parts, and less prone to shaking or deviation, thus ensuring the accuracy and reliability of the push-out operation. At the same time, the rear sides of the two ends of the right end of the push plate 21 protrude from the rear side of the middle part of the push plate 21, which can also play a limiting role to prevent the metal parts from slipping or deviating during the push-out process, further improving the safety and stability of the push-out operation.

[0046] The rear surface of the push plate 21 is bonded with a rubber protective pad.

[0047] The rubber protective pad can increase the friction between the push plate 21 and the metal parts, preventing the metal parts from being damaged due to sliding during the push-out process, thus protecting the metal parts. At the same time, the rubber protective pad also has a certain cushioning effect, which can reduce the collision force between the metal parts and the push plate 21, further reducing the risk of damage to the metal parts.

[0048] Working principle: During use, after the die-casting mold completes the die-casting operation, the top seat 4 rises under the action of external driving force, causing the four sets of connecting sleeves 12 fixedly installed on the lower side of the top seat 4 to rise synchronously. As the four sets of connecting sleeves 12 rise, under the action of the four sets of first return springs 14, they push the four sets of connecting rods 11, which are movably inserted in the four sets of movable slots 13, to slide downwards. Furthermore, as the top seat 4 rises, it pulls the four sets of connecting rods 11 and the four sets of connecting sleeves 12 upwards. During this process, the top plate 6, the four sets of connecting columns 7, and the connecting plate 8 rise as a whole under the action of the tensioning assembly. The protrusion slides stably within the die-casting groove 10, ensuring that the top plate 6 can smoothly and accurately eject the die-cast metal parts. At the same time, the push-pull assembly also begins to move synchronously. The rise of the top seat 4, through the rotation of the two sets of rotating rods 19, drives the two sets of connecting seats 18 and the two sets of push rods 17 fixedly connected to them to slide forward within the two sets of guide sleeves 16. This sliding process causes the push plate 21 fixedly installed at the front end of the two sets of push rods 17 to move forward, thereby pushing out the ejected metal parts and realizing the unloading operation of the metal parts. After being pushed out, the metal parts slide smoothly down along the inclined guide plate 22 set at the rear end of the fixed mold 9.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
