BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 A structural diagram of a mold assembly proposed by the present invention;

[0024] Figure 2 This is a schematic diagram of a mold assembly proposed by the present invention. DETAILED DESCRIPTION

[0025] refer to Figure 1-2 The present invention proposes a mold assembly, including: a first mold, a second mold and a driving assembly, and each part works together to complete the casting process of the cast ball.

[0026] The first mold is composed of a first template 11 and a second template 21, which can be assembled to form a first cavity group for casting ball molding.

[0027] The second mold includes a third mold plate 31 and a fourth mold plate 41 , which can be assembled to form a second cavity group.

[0028] The first template 11 and the fourth template 41 are fixedly connected, and the connection surfaces are the side of the first template 11 facing away from the first die 12 and the side of the fourth template 41 facing away from the fourth die, forming a basic frame of the mold.

[0029] The driving assembly connects the third template 31 and the second template 21, and realizes the opening and closing of the first cavity group and the second cavity group by driving the relative movement of the two, thereby meeting the requirements of ball casting molding and demoulding.

[0030] The cavity group is the core area of ​​the casting ball molding. Its structural design directly determines the shape and precision of the casting ball, which is specifically achieved through the cooperation between the die and the molding components.

[0031] The first die 12 is provided with a first forming assembly 13 , and the second die 12 is provided with a second forming assembly, and the two are mirror-symmetrical structures.

[0032] When the first die 12 and the second die are assembled, the first molding assembly 13 and the second molding assembly are docked to form a first cavity group.

[0033] The third die 32 is provided with a third forming component 33 , and the fourth die 32 is provided with a fourth forming component, which are also mirror-symmetrical.

[0034] After the third die 32 and the fourth die are assembled, the third molding assembly 33 and the fourth molding assembly are docked to form a second cavity group.

[0035] The cavity group forms the molding space of the spherical casting ball by splicing the trough body. The design adopts a multi-cavity structure to improve production efficiency:

[0036] First cavity group:

[0037] The first molding assembly 13 includes a plurality of first troughs 14 , and the second molding assembly includes a plurality of second troughs, which are equal in number and correspond one to one.

[0038] The first groove body 14 and the second groove body are both semi-spherical, and after being assembled, a complete spherical first cavity is formed. For example, if the first molding assembly has 6 first groove bodies, the second molding assembly corresponds to 6 second groove bodies, and after being assembled, 6 spherical first cavities are formed.

[0039] Second cavity group:

[0040] The third forming assembly 33 includes a plurality of third slots 34 , and the fourth forming assembly includes a plurality of fourth slots, the number of which corresponds to each other and all of which are semi-spherical.

[0041] After being assembled, multiple spherical second cavities are formed, which have the same structure as the first cavity group and can produce cast balls synchronously or independently.

[0042] Pouring is the key structure for introducing molten metal into the mold cavity, ensuring that the molten metal evenly fills all cavities. It specifically includes pouring troughs, gaps, runners and interfaces:

[0043] The first template 11 is provided with a first pouring trough 15 , and the second template 21 is provided with a second pouring trough. The two are combined to form a first runner, which serves as the main channel for the molten metal.

[0044] The first molding component 13 has a first notch 16 connected to the first pouring trough 15, and the second molding component has a second notch connected to the second pouring trough. After assembly, the first notch 16 and the second notch form a first interface, connecting the first runner to the first cavity group.

[0045] The third template 31 is provided with a third pouring trough 35 , and the fourth template 41 is provided with a fourth pouring trough, which form a second runner after being assembled.

[0046] The third molding component 33 has a third notch 36 connected to the third pouring trough 35, and the fourth molding component has a fourth notch connected to the fourth pouring trough. After assembly, the third notch 36 and the fourth notch form a second interface connecting the second runner and the second cavity group.

[0047] To achieve uniform distribution of molten metal among multiple cavities, adjacent cavities are connected through connectors:

[0048] A first connection port 17 is provided at the tangent point of adjacent first trough bodies 14, and a second connection port is provided at the tangent point of adjacent second trough bodies. After being assembled, multiple first cavities are connected in series. Only the first first trough body is connected to the first runner through the first notch, and the molten metal flows through each cavity in turn.

[0049] A third connecting port 37 is provided at the tangent point of adjacent third trough bodies 34, and a fourth connecting port is provided at the tangent point of adjacent fourth trough bodies. After being assembled, multiple second cavities are connected in series. Similarly, only the first third trough body is connected to the second runner through the third notch.

[0050] To further improve production efficiency, the mold can be equipped with multiple cavity groups that share the same pouring system:

[0051] The first template 11 is provided with a plurality of first molding components 13, and the second template 21 is provided with a corresponding number of second molding components. Each group is assembled to form an independent first cavity group. All first cavity groups are connected to the first runner to achieve one-time casting and production of multiple groups of cast balls.

[0052] The third template 31 is provided with a plurality of third molding components 33 , and the fourth template 41 is provided with a corresponding number of fourth molding components, which are assembled to form a plurality of second cavity groups, all connected to the second runner, and symmetrical with the first mold structure.

[0053] The drive assembly is responsible for controlling the opening and closing of the mold and uses a cylinder drive to achieve stable linear motion:

[0054] It includes a first cylinder group 5 and a second cylinder group 6 , wherein the first cylinder group is connected to the third mold plate 31 , and the second cylinder group is connected to the second mold plate 21 .

[0055] When the first cylinder group is extended or retracted, the third die plate 31 is driven to move closer to or away from the fourth die plate 41 , thereby achieving closing (molding) and opening (demolding) of the second cavity group.

[0056] When the second cylinder group is extended or retracted, the second die plate 21 is driven to move closer to or away from the first die plate 11, thereby closing and opening the first cavity group.

[0057] The length directions of the first cylinder group 5 and the second cylinder group 6 are parallel (eg, both in the horizontal direction), ensuring uniform force when the mold is opened and closed, and avoiding cavity misalignment affecting the casting accuracy.

[0058] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and the inventive concept of the present invention, should be covered by the scope of protection of the present invention.
