The above-mentioned solution solves the problem that in the existing casting production process, after the casting is formed in the mold, it is necessary to knock the mold to achieve demolding, which easily causes damage to the mold and damage to the casting, and the operation is very inconvenient.

[0023] According to the present specific embodiment, the support frame 102 is fixedly connected to the base 101 and is located above the base 101. The cylinder 103 is fixedly connected to the support frame 102 and is located on the support frame 102. The upper part of the upper mold 104 has a liquid injection port 116 and an air outlet 114. The upper mold 104 is connected to the output end of the cylinder 103. The base 101 has a cavity 115. The lower mold 105 is arranged above the cavity 115. The ejector assembly is arranged in the cavity 115. When casting, the ejector assembly is activated. The cylinder 103 extends out from its output end and pushes the upper mold 104 downward to combine with the lower mold 105, and then injects the molten metal into the cavity door of the lower mold 105 through the injection port 116. At the same time, the air in the mold and the molten metal at the air outlet 114 is used to avoid bubbles in the casting that reduce the quality of the casting. After the casting is formed and cooled naturally, the cylinder 103 drives the upper mold 104 to separate from the lower mold 105, and then the ejector assembly is used to push the molded mold out of the lower mold 105.

[0024] The driving member is fixedly connected to the base 101 and is located in the cavity 115. One end of the connecting rod 106 is connected to the driving member. The round shaft 108 is connected to the other end of the connecting rod 106. The movable frame 107 is movably connected to the round shaft 108 and is located in the cavity 115. The push plate 110 is arranged in the lower mold 105. The two ends of each movable rod 109 are respectively fixedly connected to the movable frame 107 and the push plate 110, and the two movable rods 109 are movably connected to the lower mold 105 and penetrate the lower mold 105. After the casting is naturally cooled, the cylinder 103 is started, the output end of the cylinder 103 is retracted, and the upper mold 104 is driven to separate from the lower mold 105, and then the cavity 115 is started. The driving member drives one end of the connecting rod 106 to rotate, and the other end of the connecting rod 106 drives the round shaft 108 to move in the movable frame 107. At this time, the movable frame 107 will be pushed upward by the round shaft 108, and the movable frame 107 will simultaneously drive the two movable rods 109 to push the push plate 110 upward, and the push plate 110 will push the casting in the lower mold 105 outward. Finally, the personnel will take the molded casting and continue to control the rotation of the connecting rod 106. The round shaft 108 will pull the movable frame 107 downward to reset, so that the push plate 110 moves down and resets in the lower mold 105. Through the above method, it is achieved that the molded casting can be quickly separated from the mold, thus avoiding damage to the mold and damage to the casting, and the operation is very simple.

[0025] Secondly, the spring 111 is arranged in the cavity 115, and the two ends of the spring 111 are fixedly connected to the movable frame 107 and the base 101 respectively. By setting the spring 111, the spring 111 expands and contracts as the movable spring 111 moves, and the spring 111 can increase the stability of the movable frame 107 when it moves.

The support seat 112 fixedly supports the drive motor 113 in the cavity 115, and the output end of the drive motor 113 controls the rotation of the connecting rod 106.

[0027] When casting, the cylinder 103 is started, the output end of the cylinder 103 extends out, and pushes the upper mold 104 downward to combine with the lower mold 105, and then the molten metal is injected into the cavity door of the lower mold 105 through the injection port 116. At the same time, the air in the mold and the molten metal at the outlet 114 is used to avoid bubbles in the casting and reduce the quality of the casting. After the casting is formed and cooled naturally, the cylinder 103 drives the upper mold 104 to separate from the lower mold 105, and then the drive motor 113 in the support seat 112 is started. The drive motor 113 drives one end of the connecting rod 106 to rotate, and the other end of the connecting rod 106 is rotated. One end drives the circular shaft 108 to move in the movable frame 107. At this time, the movable frame 107 will be pushed upward by the circular shaft 108. The movable frame 107 simultaneously drives the two movable rods 109 to push the push plate 110 upward. The push plate 110 pushes the casting in the lower mold 105 outward. Finally, the personnel take the molded casting and continue to control the rotation of the connecting rod 106. The circular shaft 108 will pull the movable frame 107 downward to reset, so that the push plate 110 moves down and resets in the lower mold 105. Through the above method, it is possible to quickly detach the molded casting from the mold, avoid damage to the mold and damage to the casting, and the operation is very simple.
