[0002] A mold is a process tool used to shape or mold materials (such as metals, plastics, glasses, ceramics, etc.). It usually consists of two or more mutually cooperating components, which can be used to shape the shape, size, and structure of the materials. Molds are essential in many manufacturing processes, especially in industries involving mass production of complex components.

[0003] During the process of shaping and molding materials, pouring is an essential process. It can pour molten or plastic materials into the mold, so that the materials can be accurately filled into the mold to form the required shape and size. To complete this process, a pouring machine is needed.

[0004] In the prior art, when using a mold to pour aluminum parts, first close the mold, use a fixture to fix multiple molds together, and then remove the mold by knocking, prying, etc. after the poured aluminum water cools and forms.

[0005] Although the prior art has solved certain problems, it still has the following disadvantages:

[0006] In the prior art, when demolding aluminum parts, other hard prying tools are needed to demold the finished aluminum parts, which is easy to cause damage to the aluminum parts. Moreover, when knocking and prying, the force applied to the aluminum parts is uneven, and the aluminum parts and the inner cavity of the mold are prone to extrusion, making demolding difficult, and the mold closing and opening are relatively complex. Content of the Utility Model

[0007] The purpose of the utility model is to provide a horizontal gravity pouring machine.

[0008] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0032] Embodiment 1:

[0033] As Figures 1 to 3 shown, this embodiment provides a horizontal gravity casting machine, which includes a base 1, a mold opening and closing assembly 2, a guiding mechanism 3, a mold ejection assembly 4, a mold fixing mechanism 5, a bed body 6, a communication hole 7, a mounting baffle 8, and an ejection hole 10 opened in the middle of the upper side of the lower template 402.

[0034] Among them, a bracket-shaped bed body 6 is fixedly connected to the lower end of the base 1. Four corner positions at the lower end of the outer part of the bed body 6 are fixedly connected with supporting feet 9, which facilitates the fixation of the bed body 6 and the base 1. Mounting baffles 8 are fixedly connected to both sides of the upper end of the base 1. A guiding rod 301 is arranged before and after between the mounting baffles 8. The front guiding rod 301 is on the lower side between the mounting baffles 8, and the rear guiding rod 301 is on the upper side between the mounting baffles 8. Both ends of the two guiding rods 301 extend to the side far away from each other of the mounting baffles 8, and are threadedly connected with both ends of the guiding rods 301 through nuts 302 to fix the guiding rods 301 on the mounting baffles 8. Movable templates 201 are arranged on both sides between the mounting baffles 8. The front and rear ends of the movable templates 201 are respectively penetrated by the two guiding rods 301, so that the movable templates 201 are sleeved on the upper side of the guiding rods 301, and the movable templates 201 are slidably connected with the guiding rods 301, enabling the movable templates 201 to be limited by the guiding rods 301. The two movable templates 201 can only slide to both sides, approaching or moving away from each other.

[0035] In order to control the movement of the two movable templates 201 approaching or moving away from each other, mold opening and closing cylinders 202 are fixedly connected to both sides far away from each other of the two mounting baffles 8. The telescopic rods on the side approaching each other of the mold opening and closing cylinders 202 pass through the mounting baffles 8 and are fixedly connected to the sides far away from each other of the movable templates 201. The telescopic movement of the two mold opening and closing cylinders 202 is used to control the two movable templates 201 to approach or move away from each other. A fixed plate 401 is fixedly connected to the lower end inside the bed body 6. A core ejecting cylinder 403 is fixedly connected to the lower side of the fixed plate 401. The telescopic rod at the upper end of the core ejecting cylinder 403 passes through the communication hole 7 opened at the lower end of the base 1 and extends to the ejection hole 10 opened in the middle of the upper end of the lower template 402.

[0036] In order to fix and install the combined aluminum mold, bottom mold clamping grooves 502 are opened at the front and rear of the upper side of the lower template 402. The cross-section of the bottom mold clamping groove 502 is T-shaped to fix the bottom mold of the mold. There is a hole in the middle of the bottom mold of the mold, and there is a liftable module inside the hole. After the module descends, the hole in the bottom mold is blocked to achieve sealing. After the aluminum parts inside the mold are cooled, the telescopic rod at the upper end of the core pushing cylinder 403 extends to lift the liftable module in the middle of the bottom mold to help push out and demold the aluminum parts.

[0037] In order to install the molds on the sides of the combined mold, side mold clamping grooves 501 are opened at the front and rear of the mutually adjacent sides of the moving template 201. Through the side mold clamping grooves 501, it is convenient to fixedly install the side molds and the moving template. The side mold clamping grooves 501 are horizontal, which can prevent the side templates from moving up and down due to gravity and ensure the stability of the side molds. The bottom mold clamping grooves 502 also open from front to back and are distributed towards both sides, which can prevent the bottom mold of the mold from moving to both sides and ensure that the bottom mold remains stable on the lower template 402 when the two side molds move towards both sides along with the moving template 201.

[0038] Fix the bottom mold of the mold on the lower template 402 through the bottom mold clamping grooves 502, pass the liftable module on the bottom mold through the small hole on the bottom mold, and let the bottom end of the liftable module pass through the inside of the ejection hole 10 and the inside of the communication hole 7, which is convenient for the telescopic rod at the upper end of the core pushing cylinder 403 to push out the liftable module. Fix the two mold halves that can be closed of the mold on the moving template 201 respectively. When the two mold halves approach each other along with the moving template 201, they can be combined with the bottom mold for closing the mold. Pour molten aluminum into the mold through the pouring gate at the upper end after closing the mold. After the molten aluminum solidifies and cools, use the opening and closing mold cylinders 202 on both sides to move the two side molds away from each other. The formed aluminum parts are clamped on the bottom mold by the liftable module on the bottom mold. Then, the telescopic rod at the upper end of the core pushing cylinder 403 pushes the liftable module on the bottom mold upward to separate the aluminum parts from the bottom mold, which is convenient for picking up the aluminum parts.

[0039] The combined mold is an existing product on the market and is prior art, so it will not be elaborated here.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
