[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The ball casting mold is a mold used to manufacture metal spheres. In the ball casting production, metal liquid is injected into the mold, and after cooling and solidification, a metal sphere is formed. However, the existing ball casting mold can only form a small number of balls at one time, so it is somewhat weak when facing mass production of cast balls and the production capacity is not high.

[0026] Embodiment 1:

[0027] Based on the technical defects of the existing technology in the low production quantity of ball casting molds, please refer to Figure 1-Figure 5 The utility model provides a mold for producing cast balls, wherein movable molds 3 are arranged on both sides of a fixed mold 2, so that more cast balls can be formed at one time, which greatly improves production efficiency and has high production capacity. The mold comprises a bracket 1, a fixed mold 2 is fixedly arranged on the top of the bracket 1, and movable molds 3 are arranged on both sides of the fixed mold 2. A plurality of groups of vertically arranged mold cavities 4 are arranged on the contact surfaces of the fixed mold 2 and the movable mold 3, and the mold cavity 4 is hemispherical. A connecting hole 5 is arranged between the plurality of vertically arranged mold cavities 4. The arrangement of the connecting hole 5 can facilitate the smooth entry of metal material into each mold cavity 4 during casting. An air hole channel 7 is arranged between the plurality of vertically arranged mold cavities 4. The arrangement of the air hole channel 7 is convenient for exhausting the air inside the mold cavity 4 during casting. A pouring port 6 is arranged on the mold cavity 4 at the top, and the pouring port 6 is trumpet-shaped. The arrangement of the pouring port 6 can facilitate the pouring of metal material into the mold cavity 4 without spilling it easily.

[0028] Specifically, in order to solve the problem of opening and closing the mold during use, an opening and closing mold mechanism 8 connected to the side walls of the two movable molds 3 is fixed on both side walls of the bracket 1. The setting of the opening and closing mold mechanism 8 can control the movement of the two movable molds 3, thereby completing the opening and closing actions, facilitating casting and demoulding, and the opening and closing mold mechanism 8 includes a hydraulic rod 81 installed on the side wall of the bracket 1, the telescopic shaft of the hydraulic rod 81 is fixedly connected to the bottom of the sliding sleeve 82, the sliding sleeve 82 is slidably mounted on the side wall of the bracket 1, the side wall of the sliding sleeve 82 is hinged to one end of the two push rods 83, and the other ends of the two push rods 83 are respectively hinged to the side walls of the two movable molds 3.

[0029] Specifically, during the mold opening and closing process, the two movable molds 3 need to move on both sides. In order to avoid shaking during the movement, a limit assembly 9 connected to the two movable molds 3 is provided on one side of the fixed mold 2. The setting of the limit assembly 9 can make the two movable molds 3 more stable and reduce shaking during the mold opening and closing movements. The limit assembly 9 includes a scissor rod 91 rotatably connected to the side wall of the fixed mold 2. The two sides of the scissor rod 91 are respectively rotatably connected to two sliders 92. The two sliders 92 are respectively slidably set in two slide grooves opened on the side wall of the movable mold 3.

[0030] Furthermore, when the ball is cast, there is still excess air remaining in the metal material, which affects the quality of the ball casting. To solve this problem, a vibration motor 14 is fixedly provided at the bottom of the fixed mold 2. By setting the vibration motor 14, vibration can be provided during pouring. The vibration can help the metal material to be filled more evenly in the mold, reduce the generation of pores and defects, and improve the quality of the cast ball.

[0031] According to the embodiment, during pouring, the molten metal material is poured into the mold cavity 4 from the pouring port 6. After the cast ball inside the mold cavity 4 is formed, the hydraulic rod 81 is started and drives the sliding sleeve 82 to move upward. The sliding sleeve 82 drives the two movable molds 3 to move outward through the push rod 83, thereby performing a mold opening action. After the mold is opened, the cast ball can be manually taken out of the mold cavity 4. After the cast ball is taken out, the hydraulic rod 81 is reset, thereby resetting the two movable molds 3 and performing a mold closing action, and then the pouring is repeated.

[0032] Embodiment 2:

[0033] When casting balls, natural cooling is generally used, but natural cooling is inefficient and takes a long time. To solve this problem, please refer to Figure 4 On the basis of the first embodiment, a cooling cavity 10 is further provided inside the fixed mold 2 .

[0034] Furthermore, a water inlet pipe 11 and a water outlet pipe 13 connected to the cooling cavity 10 are connected to the side wall of the fixed mold 2, and a valve 12 is installed on the water inlet pipe 11; cooling water can be introduced into the cooling cavity 10, thereby accelerating the cooling and solidification of the cast ball and improving the casting efficiency.

[0035] According to the embodiment, after the valve 12 is opened, cooling water enters the cooling cavity 10 through the water inlet pipe 11, cools the cast ball, and then is discharged through the water outlet pipe 13.

[0036] Through the above embodiments, it can be known that the use process of the device is as follows: during casting, the molten metal material is poured into the mold cavity 4 from the pouring port 6. After the casting is completed, the valve is opened, and the cooling water enters the cooling cavity 10 through the water inlet pipe 11 to cool the cast ball. After the cast ball inside the mold cavity 4 is formed, the hydraulic rod 81 is started and the sliding sleeve 82 is driven to move upward. The sliding sleeve 82 drives the two movable molds 3 to move outward through the push rod 83, thereby performing a mold opening action. After the mold is opened, the cast ball can be manually taken out of the mold cavity 4. After the cast ball is taken out, the hydraulic rod 81 is reset, thereby resetting the two movable molds 3 and performing a mold closing action, and then the casting can be repeated.
