[0006] As a further improvement of the above scheme, the fixed transfer film mold core holes are symmetrically distributed with the vent hole as the axis, and there are four of them. Two anti-foolproof positioning blocks are provided, and the two anti-foolproof positioning blocks are vertically distributed. An air hole is opened at the bottom of the transfer film mold core, and a corresponding anti-foolproof positioning groove is opened at the bottom of the transfer film mold core.

[0007] As a further improvement of the above solution, the mounting seat is engaged with the surface of the transfer film base, and the fastening bolt is rotated from the surface of the mounting seat and connected into the interior of the transfer film base, so that the mounting seat is fixedly connected to the interior of the transfer film base.

[0008] As a further improvement of the above solution, a meshing plate is fixedly connected to one side of the dust cover, a rubber pad is fixedly connected to one side of the meshing plate, the rubber pad is located in the central area of ​​the meshing plate, and the rubber pad is arranged on the left, right and upper sides of the dust cover.

[0009] As a further improvement of the above solution, the locking mechanism includes a fixed frame, a rotating shaft is fixedly connected to the inner wall of the fixed frame, a torsion spring is sleeved on the surface of the rotating shaft, and a T-shaped sliding groove is opened on the inner wall of one side of the fixed frame.

[0010] As a further improvement of the above scheme, one end of the torsion spring is fixedly connected to the inner wall of the fixed frame, the other end of the torsion spring is fixedly connected to a lock, the lock is rotatably connected to the rotating shaft, a pin is inserted into the inside of the T-shaped slide groove, and the shape and size of the pin are engaged with the groove shape of the T-shaped slide groove.

[0011] As a further improvement of the above scheme, a baffle is fixedly connected to the top side of the lock head, an oblique opening is provided on the surface of the lock head away from the baffle, an arc opening is provided on the bottom of the lock head, and the baffle and the surface of the pin are in contact with each other but are not fixedly connected.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This kind of mold structure solves the problem of pulp molded products not being demolded during transfer. By designing the transfer mold into an inlaid structure, a certain space is formed between the mold core and the bottom plate, which is conducive to the flow of vacuum and air pressure. At the same time, the vent holes are enlarged, and the flow of air pressure and vacuum is increased, making the product easier to be transferred by the transfer mold; at the same time, the transfer mold inlay design saves mold costs.

[0014] 2. This mold structure solves the problem of pulp molded products not being demolded during transfer. When the transfer film base is not in use, long-term placement will cause dust to enter the vacuum buffer space. For this purpose, a dust cover is set. When dust prevention is needed, first remove the transfer film core, then rotate and lower the dust cover along the mounting seat, and then make the engaging plate engage with the inner wall of the transfer film base. At the same time, the rubber pad is covered at the connection between the transfer film base and the rubber pad, which effectively prevents the entry of liquid. When the dust cover is fully pressed into the interior of the transfer film base, the hollow buckle ring will enter the locking mechanism. The inside of the structure allows the hollow buckle to push open the lock head. Due to the oblique opening, the lock head is easier to be pushed open. When the hollow buckle is fully inserted, the lock head will be stuck in the hollow buckle to avoid the dust cover from loosening and detaching. When it needs to be unlocked, the pin is pulled out of the T-shaped slide groove, and then the lock head is turned over. Without the obstruction of the pin, the baffle can enter the internal space of the T-shaped slide groove to realize the flipping of the lock head, so that the hollow buckle is detached from the inside of the locking mechanism, which effectively improves the dustproof effect of the transfer film base and avoids the influence on the subsequent processing technology.
