[0002] At present, the molding of castings generally adopts the pouring method, and the current pouring method is to inject the raw material into the mold in the form of liquid and cool it to form the casting.

[0003] However, the current castings are closely fitted to the mold after molding, and it is difficult to separate the two, so there is room for improvement. Summary of the invention

[0004] The object of the present invention is to provide an injection device for castings to solve the problems raised in the above-mentioned background technology, which has the advantage of conveniently separating the castings from the mold.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an injection device for castings, comprising an input pump body, the input pump body is connected to an input pipe, one end of the input pipe is installed with a mold assembly, the mold assembly comprises a mold body, an upper cover is installed above the mold body, a through groove for inserting the input pipe is penetrated in the middle of the upper cover, two fixed blocks in the circumferential direction of the through groove are integrally connected to the upper side of the upper cover, an extrusion piece for extruding the input pipe is arranged above the two fixed blocks, each of the fixed blocks is penetrated with a fixed shaft, the fixed shaft is sleeved with an L-shaped rod, a circular groove is arranged above the mold body, a round rod that is movably inserted into the circular groove is arranged at one end of the L-shaped rod, and a moving piece for driving the round rod to move is arranged inside the L-shaped rod.

[0006] By adopting the above technical scheme, the input pump body is used to input concrete into the mold assembly along the input pipe, so as to achieve the purpose of pouring. The input pipe is inserted between the two fixed blocks and fixed by the extrusion piece. Before the input pipe passes through the upper cover for pouring, the L-shaped rod is rotated until one end of the L-shaped rod is on both sides of the circular groove, and then the round rod is driven to move into the circular groove by the moving part. When the round rod is in the circular groove, the upper cover is cooperated to form a sealed space with the mold body. After pouring, after the pouring liquid cools to form a casting, the moving part is used to drive the round rod to continue to move inward until the round rod extrude the casting, and the fixed block is moved upward to drive the L-shaped rod upward to move upward, and then drive the round rod upward to move the casting clamped by the round rod to move upward. After the casting rises to a certain height and is separated from the mold body, the casting is taken away by an external manipulator. During this process, the round rod moves slightly outward and does not block the manipulator from carrying the casting.

[0007] As a further solution of the present invention: the moving part includes a moving motor fixedly connected to the L-shaped rod, the output shaft of the moving motor is threadedly connected to the round rod, the side of the round rod is integrally connected with a limiting strip, and the interior of the L-shaped rod is provided with a limiting groove for accommodating the limiting strip and the length direction of which is consistent with the length direction of the round rod.

[0008] By adopting the above technical solution, the moving motor is started to drive the round rod to move along its own length direction. During this process, the limit bar is always in the limit groove and can only move along the length direction of the limit groove. The cooperation between the limit bar and the limit groove limits the rotation of the round rod.

[0009] As a further solution of the present invention: a first lifting cylinder is arranged above the mold body, and the first lifting cylinder is connected to the fixing block.

[0010] By adopting the above technical solution, the first lifting cylinder is used to drive the fixing block to move up and down, thereby driving the upper cover to move up and down.

[0011] As a further solution of the present invention: a positioning block is integrally connected to the side of the mold body, and a second lifting cylinder connected to the positioning block is arranged above the mold body.

[0012] By adopting the above technical solution, the second lifting cylinder is used to drive the positioning block to move up and down, thereby driving the mold body to move up and down.

[0013] As a further solution of the present invention: a semicircular plate is integrally connected to the top of each of the fixing blocks, the extrusion piece includes a nut threadedly connected to the two semicircular plates, and a convex strip is integrally connected to the sides of the semicircular plates facing each other.

[0014] By adopting the above technical solution, after the input tube is inserted into the two fixing blocks along the middle of the nut, the rotating nut moves toward the fixing block. As the nut rotates, the two semicircular plates will rotate in a direction close to each other and then drive the convex strips to rotate in a direction close to each other until the convex strips squeeze the input tube, thereby fixing the input tube.

[0015] As a further solution of the present invention: a cooling pool is arranged below the mold assembly, a lifting cylinder is arranged above the cooling pool, and the lifting cylinder is connected to a lifting block.

[0016] By adopting the above technical solution, the mold assembly is moved down to the cooling pool and cooled using the moisture in the cooling pool. After the mold assembly is moved down, the positioning block will be above the lifting block. The lifting cylinder is started to drive the lifting block up and down, thereby driving the mold body up and down to adjust the depth of the mold body in the cooling pool.

[0017] As a further solution of the present invention: two first concave plates are fixedly connected above the cooling pool, the two first concave plates are slidably connected to the same knocking rod, and a driving member is provided in the middle of the knocking rod for driving the knocking rod to move repeatedly along its own length direction.

[0018] By adopting the above technical solution, after the casting is formed in the mold body, the two fit closely. At this time, the driving part can be used to drive the knocking rod to move repeatedly and then let the knocking rod repeatedly knock the side of the mold body, which plays a role in preliminary separation of the two, making it easier to use the round rod to extrude the casting to drive the casting and the mold body to separate.

[0019] As a further solution of the present invention: a receiving groove is provided inside the cooling pool, and a driving member is provided in the receiving groove, and the driving member includes a rotating motor located in the middle of the receiving groove and fixedly connected to the receiving groove, the output shaft of the rotating motor is connected to a first rotating rod, the first rotating rod is rotatably connected to a second concave plate, the second concave plate is slidably connected to a second rotating rod, the middle part of the knocking rod is integrally connected to a triangular plate, and one end of the second rotating rod is rotatably connected to the triangular plate.

[0020] By adopting the above technical solution, the rotating motor is started to drive the first rotating rod to rotate and then drive the second concave plate to rotate. The rotation of the second concave plate drives the second rotating rod in the second concave plate to move left and right. The movement of the second rotating rod drives the knocking rod to move left and right. Under the restriction of the two first concave plates, the knocking rod can only move along its own length direction.

[0021] As a further solution of the present invention: the bottom of the accommodating groove is fixedly connected with a matching block, one side of the matching block is integrally connected with a fixing rod, the fixing rod is rotatably connected with a third concave plate, and the third concave plate is sleeved on the outside of the second rotating rod.

[0022] By adopting the above technical solution, one end of the second rotating rod is located in the third concave plate. During the movement of the knocking rod, the second rotating rod moves left and right. During this process, the third concave plate swings left and right, thereby stabilizing the second rotating rod.

[0023] As a further solution of the present invention: a rotating motor for driving the L-shaped rod to rotate is arranged in the fixed block.

[0024] By adopting the above technical solution, the setting of the rotating motor allows the L-shaped rod to rotate around the axis of the fixed shaft.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The input pump body is used to input concrete into the mold assembly along the input pipe, so as to achieve the purpose of pouring. The input pipe is inserted between the two fixed blocks and fixed by the extrusion piece. Before the input pipe passes through the upper cover for pouring, the L-shaped rod is rotated until one end of the L-shaped rod is on both sides of the circular groove, and then the round rod is driven to move into the circular groove by the moving part. When the round rod is in the circular groove, the upper cover is cooperated to form a sealed space with the mold body. After pouring, after the pouring liquid cools to form a casting, the moving part is used to drive the round rod to continue to move inward until the round rod extrude the casting, and the fixed block is moved upward to drive the L-shaped rod upward, and then drive the round rod upward, thereby driving the casting clamped by the round rod to move upward. After the casting rises to a certain height and is separated from the mold body, the casting is taken away by an external manipulator. During this process, the round rod moves slightly outward and does not block the manipulator from carrying the casting. BRIEF DESCRIPTION OF THE DRAWINGS
