Referring to fig. 1-7, the present embodiment is a mold opening and closing sequence control apparatus 100 for installing on a mold structure having a female mold assembly 200 and a male mold assembly 300, and controlling the opening and closing sequence of the female mold assembly 200 and the male mold assembly 300. The master mold assembly 200 includes a master mold backing plate 201 and a master mold floating carrier plate 202, and the male mold assembly 300 includes a male mold backing plate 301 and a male mold floating carrier plate 302.
The die opening and closing sequence control device 100 comprises an unlocking bayonet lock 1 fixed on a female die backing plate 201, a locking bayonet lock 2 fixed on a male die backing plate 301 and a lock catch main body 3 fixed on a female die floating bearing plate 202, wherein the free ends of the unlocking bayonet lock 1 and the locking bayonet lock 2 extend into the lock catch main body 3, a first side surface 11 of the unlocking bayonet lock 1 and a second side surface 21 of the locking bayonet lock 2 are distributed oppositely, a positioning piece 4 is movably arranged between the first side surface 11 and the second side surface 21 in the lock catch main body 3, a sliding groove 31 for limiting the horizontal movement range of the positioning piece 4 is formed in the lock catch main body 3, a buckling groove 22 matched with the positioning piece 4 is formed in the second side surface 21, and the maximum distance between the surfaces of the buckling groove 22 and the first side surface 11 is equal to the diameter of the positioning piece 4; the first side surface 11 is provided with a power acting surface 111 and a force release notch 112 along the die opening direction, and the maximum distance between the surface of the force release notch 112 and the second side surface 21 is larger than the diameter of the positioning piece 4.
In this embodiment, the positioning member 4 has a cylindrical structure, and the front-rear length thereof is greater than the front-rear thickness of the unlocking bayonet lock 1 and the locking bayonet lock 2, and the positioning member 4 is pressed by an elastic member 8 toward the second side surface 21 at a position staggered from the front-rear of the unlocking bayonet lock 1 and the locking bayonet lock 2, so as to implement a horizontal movable arrangement in the latch main body 3. The positioning member 4 does not have a degree of freedom in the mold opening and closing direction in the latch main body 3, but has a degree of freedom of float perpendicular to the mold opening and closing direction.
The lock catch main body 3 is internally provided with a mounting groove 34 for accommodating the elastic piece 8 and providing a telescopic space for the elastic piece 8, the sliding groove 31 is communicated with the mounting groove 34, and one end of the positioning piece 4 extends backwards and stretches into the mounting groove 34. The elastic member 8 is horizontally installed in the installation groove 34, and one end of the elastic member abuts against the inner wall of the installation groove 34 and the other end abuts against the positioning member 4.
The present embodiment further includes a sensor (shown in the figure) for detecting whether the master plate 201 and the master floating carrier plate 202 are completely closed, the sensor is electrically connected to a mold control system, and when the sensor detects that the master plate 201 and the master floating carrier plate 202 are not completely closed, the mold control system stops the mold closing operation and alarms to notify the operator of the previous process.
In the mold closing state, the pressing portion of the positioning member 4 by the power acting surface 111 is embedded in the buckle groove 22; when the die is opened, the locking bayonet lock 2 moves upwards along with the male die cushion plate 301, and as the positioning piece 4 is clamped in the buckling groove 22, the locking bayonet lock 2 drives the positioning piece 4, the locking main body 3 and the female die floating bearing plate 202 to move upwards, so that the female die floating bearing plate 202 is separated from the female die cushion plate 201, and the female die sliding block completes the demoulding action; after the female die floating bearing plate 202 is separated from the female die base plate 201 by a certain distance, the positioning piece 4 just moves to the position of the force release notch 112 of the unlocking bayonet lock 1, the positioning piece 4 loses the rigid supporting force for extruding the positioning piece into the buckling groove 22, and when the locking bayonet lock 2 continues to move upwards, the positioning piece 4 moves horizontally to be separated from the buckling groove 22 and slides into the force release notch 112, and at the moment, the control device 100 is in an unlocking state; the male mold assembly 300 continues to open, the male mold floating carrier plate 302 is randomly separated from the female mold floating carrier plate 202, and the product is ejected and demolded.

In this embodiment, a first slot 32 through which the unlocking pin 1 is inserted or passes and a second slot 33 through which the locking pin 2 is inserted or passes are provided in the latch main body 3.
In this embodiment, the male mold component 300 and the female mold component 200 are disposed in a mode of opening and closing the molds, and in this mold structure, the movement of the positioning member 4 is horizontal movement, as shown in fig. 3. In other embodiments, the male module 300 and the female module 200 may be disposed in a form of horizontal opening and closing, and in this structural form, the sliding direction of the positioning member 4 in the latch main body 3 may be correspondingly disposed to slide up and down, as shown in fig. 7.
In order to facilitate the smoothness of the sliding of the positioning member 4, an arc-shaped guide surface 113 is formed on the inner wall surface of the force release notch 112 so that the positioning member 4 can smoothly slide into or out of the force release notch 112.
The surrounding angle of the buckling groove 22 is smaller than 180 degrees, so that the positioning piece 4 can be smoothly separated from the buckling groove 22, and the phenomenon of die clamping is prevented, so that a die cannot be normally opened.
In this embodiment, a first mounting plate 5 is disposed on a master die pad 201, and one end of an unlocking bayonet 1 is fixed on the first mounting plate 5; the female die floating bearing plate 202 is provided with a second mounting plate 6, and the lock catch main body 3 is fixed on the second mounting plate 6; the male die pad 302 is provided with a third mounting plate 7, and one end of the locking bayonet 2 is fixed to the third mounting plate 7.
