In short, the mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry".

[0003] In order to be able to inject workpieces of different shapes, the casting inner mold inside the existing metal mold is usually removable and replaceable.

[0004] At present, the installation and disassembly process of metal molds is relatively cumbersome, and there are through holes in the inner mold, which affects the normal use of the inner mold. At the same time, it is not convenient to take out the disassembled inner mold. Therefore, it is necessary to propose a metal mold that is easy to disassemble and assemble to solve the above problems. Utility Model Content

[0007] The front, back, left, and right sides of the lower die base are all fixedly connected with positioning plates, the front, back, left, and right sides of the inner wall of the lower die base are all fixedly connected with support platforms, and the upper end surfaces of the four support platforms are all fixedly connected with positioning columns inserted into the positioning plates.

[0008] In order to limit the position of the fixing rod, as a preferred metal mold of the utility model that is easy to disassemble and assemble, the front end surface of the movable plate is penetrated by a limiting groove, and the outer wall of the fixing rod is fixedly connected with a pull rod extending to the outside of the limiting groove.

[0009] In order to enable the movable plate to move left and right smoothly, as a preferred metal mold of the utility model that is easy to disassemble and assemble, both left and right sides of the upper end surface of the base are penetrated by through grooves that are connected to the cavity.

[0010] In order to drive the movable plate to move left and right, as a preferred embodiment of the utility model of a metal mold that is easy to disassemble and assemble, rotating rods fixedly connected to the threaded rods are installed on both the left and right sides of the base.

[0011] In order to sleeve the positioning plate onto the outside of the positioning column, as a preferred embodiment of the utility model of a metal mold that is easy to disassemble and assemble, a through hole is formed through the upper end surface of the positioning plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model first pulls the fixing rod upwards, so that the fixing rod drives the inner mold to move upwards, until the inner mold moves out of the lower mold seat, thereby facilitating the removal of the inner mold, and then rotates the threaded rod to cause the two movable plates to drive the fixing rods away from each other, until the two fixing rods are separated from the fixing grooves, thereby releasing the restriction on the inner mold, thereby facilitating the removal of the inner mold from the lower mold seat;

[0014] When the inner mold needs to be installed, the inner mold can be placed in the lower mold base, and the positioning plate can be sleeved on the outside of the positioning column. Then the threaded rod drives the two movable plates closer to each other, prompting the fixing rod to enter the fixing groove. At the same time, the electromagnetic plates attract each other, thereby realizing the limited fixation of the inner mold and achieving the effect of facilitating the installation of the inner mold.

Then, the electromagnetic plate 204 is disconnected, and the threaded rod 102 is rotated to cause the two movable plates 2 to drive the fixing rods 203 away from each other, until the two fixing rods 203 are separated from the fixing grooves 301, thereby releasing the restriction on the inner mold 3, thereby facilitating the removal of the inner mold 3 from the lower mold base 103.

[0032] When the inner mold 3 needs to be installed, the inner mold 3 can be placed in the lower mold base 103, and the positioning plate 302 can be sleeved on the outside of the positioning column 105. Then the threaded rod 102 is rotated to drive the two movable plates 2 to approach each other, prompting the fixing rod 203 to enter the fixing groove 301. At the same time, the electromagnetic plates 204 are attracted to each other, thereby realizing the limited fixation of the inner mold 3 and achieving the effect of facilitating the installation of the inner mold 3.
