DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered thereon. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an element centered thereon at the same time. The terms "vertical", "horizontal", "left", "right", "up", "down", "front", "rear" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0027] like Figure 1-3 As shown, a mold structure that is easy to disassemble and assemble includes a lower mold base 1 and an upper mold base 2, a casting inner mold 3 is arranged between the lower mold base 1 and the lower mold base 1, a mounting seat 4 integrally formed with the lower mold base 1 is arranged between the casting inner mold 3 and the lower mold base 1, a mounting cavity is opened in the mounting seat 4, and the casting inner mold 3 is movably arranged in the mounting cavity;

[0028] A locking mechanism is provided on the outer side of the mounting seat 4, and the locking mechanism is used to limit the freedom of the casting inner mold 3 located in the mounting cavity to move up and down relative to the mounting seat 4 when locked;

[0029] The locking mechanism includes locking components 5 arranged on two sides of the mounting seat 4 opposite to each other.

[0030] In this embodiment, a locking mechanism is provided on the outside of the mounting seat 4, the casting inner mold 3 is placed in the mounting cavity, and the locking mechanism is put into a locked state, thereby limiting the casting inner mold 3 from moving up and down relative to the mounting seat 4 and separating from the lower mold seat 1, thereby ensuring that the casting inner mold 3 is firmly connected to the lower mold seat 1; at the same time, when the casting inner mold 3 needs to be disassembled or replaced, the locking mechanism is unlocked by external force control, so that the casting inner mold 3 can be conveniently and quickly removed, and the disassembly and assembly are convenient, and the connection is stable and reliable.

[0031] Further, such as Figure 1 , 3As shown, the locking assembly 5 includes a connecting plate 51, a card block 54 is provided in the middle of the connecting plate 51, and guide rods 53 are provided at both ends opposite to each other. The guide rod 53 is only connected to the mounting seat 4 for horizontal axial sliding. The mounting seat 4 is provided with a card slot 41 that runs from the outside to the mounting cavity. The card block 54 is clearance-matched with the card slot 41. The outer side surface of the casting inner mold 3 corresponding to the card slot 41 is provided with a lock slot 31, and the card block 54 is plugged into the lock slot 31.

[0032] In this embodiment, when the casting inner mold 3 is installed, the casting inner mold 3 is first placed in the installation cavity. At the same time, an external force drives the end of the card block 54 away from the connecting plate 51 to leave the driving cavity. Then, after the casting inner mold 3 is completely placed in the installation cavity, the external force pushes the connecting plate 51 in the opposite direction, so that the end of the card block 54 away from the connecting plate 51 enters the driving cavity and is inserted into the locking groove 31, thereby locking the casting inner mold 3 during installation and unlocking it during disassembly, so that the casting inner mold 3 can be conveniently and quickly removed, and disassembly and assembly are convenient.

[0033] Further, such as Figure 1 , 3 As shown, in order to ensure smooth and reliable sliding connection between the guide rod 53 and the mounting seat 4, a guide seat 8 is provided at the sliding connection between the guide rod 53 and the mounting seat 4. A through axial hole is opened in the guide seat 8, and the guide rod 53 can be slidably arranged in the axial hole.

[0034] Further, such as Figure 1 , 3 As shown, in order to further improve the strength of the guide seat 8, the guide seat 8 and the mounting seat 4 are formed in one piece.

[0035] Further, such as Figure 1 , 3 As shown, in order to prevent the guide rod 53 from overtravel and moving away from the guide seat 8 and improve the connection reliability, the locking assembly 5 also includes a limit plate 52, which is connected to the end of the guide rod 53 away from the connecting plate 51.

[0036] Further, such as Figure 1 , 3 As shown, in order to ensure that after the casting inner mold 3 is installed in place, the block 54 can be automatically inserted into the locking groove 31 without external force, and to prevent the block 54 from being separated from the locking groove 31 when the casting inner mold 3 is in a locked state; the guide rod 53 is located between the guide seat 8 and the limit plate 52 and is sleeved with an elastic member 9. When there is no external force, the elastic member 9 is in a non-compressed state, which is convenient for disassembly and assembly, and the connection is stable and reliable.

[0037] Further, such as Figure 1 , 3 As shown, in order to improve the convenience of operation and facilitate the application of force, a gripping portion 6 is provided on one side of the connecting plate 51 away from the clamping block 54 .

[0038] Further, such as Figure 1 , 3 As shown, in order to improve the coaxial stability of the upper mold base 2 and the lower mold base 1 when opening and closing, guide holes 42 are arranged around the outer side of the upper surface of the mounting base 4, and a slidingly connected guide column 7 is arranged in the guide hole 42, and the end of the guide column 7 away from the mounting base 4 is connected to the upper mold base 2.

[0039] Furthermore, the elastic member 9 is a spring or rubber or a combination thereof.

[0040] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
