When the locking mechanism is locked, the third locking assembly 40 drives the second locking assembly 30 to be locked with the first locking assembly 20, so that the first locking assembly 20, the second locking assembly 30 and the third locking assembly 40 are in a locking state; when the locking mechanism is unlocked, the third locking assembly 40 drives the second locking assembly 30 to be separated from the first locking assembly 20, so that the first locking assembly 20, the second locking assembly 30 and the third locking assembly 40 are in an unlocked state.

The first mold 11, the second mold 12 and the third mold 13 need to ensure the order of mold opening and mold closing in the specific use process, so that the product and the mold can be ensured, or the mold and the mold cannot be mutually abutted to cause the mold to bump. In the present embodiment, a locking mechanism is provided, and the first locking component 20 can be fixedly connected with the first mold 11; the second locking assembly 30 may be associated with the second mold 12; the third locking assembly 40 can be fixedly connected with the third mold 13, and the mold opening sequence and the mold closing sequence among the first mold 11, the second mold 12 and the third mold 13 are strictly controlled through the cooperation between the first locking assembly 20 and the second locking assembly 30 as well as the third locking assembly 40, so that the collision between adjacent molds is avoided, and the mold failure is avoided.

It should be noted that, a mounting cavity of the second locking assembly 30 is disposed in the second mold 12, the mounting cavity is disposed on a side wall of the second mold 12, the side wall has an opening, and an opening is disposed on a top wall of the mounting cavity, that is, a side of the second mold 12 facing the third mold 13, and the opening is disposed to facilitate the third locking assembly 40 to cooperate with the second locking assembly 30.

The limiting pin is arranged to limit the displacement range of the locking block 32 by matching the limiting pin with the long hole 321 of the locking block 32. Limiting the displacement range of the locking block 32 can firstly prevent the locking block 32 from directly sliding out of the second mold 12 when the limitation of the first locking component 20 is completely lost, which results in the need of assembling the locking mechanism for many times.

during locking, the second mold 12 is matched with the first mold 11 in S100; s200, the third locking assembly 40 drives the second locking assembly 30 to be matched with the first locking assembly 20; s300, matching the third mold 13 with the second mold 12; when unlocking, the third mold 13 is disengaged from the second mold 12 in S400; s500, the third locking assembly 40 drives the second locking assembly 30 to be separated from the first locking assembly 20 and is released; s600 the second mold 12 is disengaged from the first mold 11.

Specifically, in the technical solution of the embodiment of the present application, the method for using the locking mechanism corresponds to the production process of the mold 10. Before the die assembly, an oblique top needs to be fixedly installed on the first die 11, then the second die 12 and the third die 13 are sequentially die assembled, in the die assembly process of the second die 12, the first driving piece 41 is in contact with and abuts against the locking block 32, the hydraulic machine pushes the third die 13 to push the second die 12 to the first die 11 through the first driving piece 41, and in the process, the third die 13 is static relative to the second die 12. When the second mold 12 and the first mold 11 complete the mold closing, the locking block 32 slides in the second direction X under the action of the elastic member 31, at this time, the locking block 32 releases the abutting against the first driving member 41, the first driving member 41 displaces along the first direction Y, the inclined surface 411b contacts with the top of the accommodating slot 322, the locking block 32 is further pushed to the second direction, when the inclined surface 411b completely enters the accommodating slot 322, the limiting section 323 and the locking portion 211 form the locking, at this time, the second locking component 30 and the first locking component 20 are locked, and the third mold 13 moves relative to the second mold 12, so as to complete the mold closing.

After the mold closing is finished, performing injection molding processing, after the product processing is finished, moving the first mold along the direction opposite to the first direction Y, at this time, since the first driving part 41 also limits the locking block 32, that is, the locking block 32 is still in the locking state, the second mold 12 and the first mold 11 are in the mold closing state, at this time, the third mold 13 moves relative to the second mold 12, and the limitation on the product is removed from the inside of the second mold 12. When the first driving member 41 is completely separated from the receiving slot 322, the protrusion 421 of the second driving member 42 contacts the inclined section 324 of the locking block 32, the second driving member 42 moves in the opposite direction of the first direction Y relative to the locking block 32, at this time, the protrusion 421 exerts a force on the inclined section 324 of the locking block 32 in the opposite direction of the second direction X, the locking block 32 is pushed into the housing 33, at this time, the limiting section 323 is unlocked from the locking section 211, when the locking block 32 is completely pushed into the housing 33, the first locking assembly 20 is separated from the second locking assembly 30, the second mold 12 is separated from the first mold 11 under the force of the third mold 13, and mold opening is completed. It should be noted that, during the mold closing process, the pressing device applies a low pressure, and if the elastic member 31 fails, the low pressure will not crush the third locking assembly 40 and the second locking assembly 30, so as to protect the mold 10.
