[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Its advantages include high production speed, high efficiency, automated operation, a wide variety of designs and colors, shapes ranging from simple to complex, and sizes ranging from large to small. Furthermore, it produces precise product dimensions, is easily updated, and can produce complex shapes. Injection molding is suitable for mass production and the molding of complex products.

[0003] In order to share costs and improve efficiency, the existing technology often uses multi-cavity synchronous molding injection molds when producing some products, so that multiple products can be produced at one time each time the mold is opened and closed. However, the work efficiency cannot meet the requirements. At this time, the existing technology will make the mold into a cube with mold grooves on the four sides, and then cooperate with the four mold heads distributed around it to carry out mold closing production to maximize production efficiency. However, the four molds around the four sides need to be controlled separately and it is not convenient to link them, which makes the control system of the entire mold more complicated and it is difficult for staff to monitor and observe the closing status of the four molds. Therefore, a multi-cavity synchronous molding injection mold is needed to solve this problem. Utility Model Content

[0008] Preferably, the moving block is movably engaged with the outer surface of the rotating ring through an annular slot. The moving block is engaged with the outer surface of the rotating ring through the annular slot, which will not affect the rotation of the rotating ring. At the same time, the rotating ring can drive the moving block to move up and down.

[0009] Preferably, a connection interface is fixedly provided on the outer surface of the first mold and the second mold, and cooling water can be easily injected into the cooling channel inside the first mold and the second mold through the connection interface, so as to cool the interior of the molding cavity.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When closing the molds, the utility model only needs to drive the screw to rotate through the motor, so that the rotating ring and the moving block can be driven up and down by the thread.
