The first plate 21 is used for placing a die, and the lifting separation and die assembly combination actions of the die are completed on the first plate 21.
The die of the first plate body 21 is transferred to the second plate body 22 through magnetic attraction, the specific structure is shown in fig. 1 and 3-6, an upper frame body is fixed at the upper end of the frame 1, and an upper screw rod assembly 33 is arranged on the upper frame body;
The upper screw rod assembly 33 comprises a sliding plate sliding on the upper frame body, the sliding plate is connected with the upper frame body through a sliding rail, a threaded sleeve is arranged on the sliding plate, the threaded sleeve is in threaded connection with an upper screw rod, the upper screw rod is rotatably connected with the upper frame body, the upper screw rod is driven by a motor, therefore, the upper screw rod assembly 33 realizes the back and forth movement of the sliding plate on the upper frame body through the forward and reverse rotation control of the motor, and the upper frame body is provided with a remote controller for controlling the forward and reverse rotation of the motor and stopping actions.
The moving direction of the upper screw rod assembly 33 is longitudinal, and the telescopic direction of the lower push rod 82 is in the same direction;
referring to fig. 1, since the first plate 21, the second plate 22 and the third plate 23 are sequentially disposed along the moving direction of the upper screw assembly 33, it is possible to accomplish the movement of lifting the form of the first plate 21 back and forth between the second plate 22 or the third plate 23.
The sliding plate of the upper screw rod assembly 33 is provided with a vertical lifting rod 32, the vertical lifting rod 32 comprises an oil cylinder and a vertical piston rod, an electromagnet 31 is fixed at the lower end of the vertical lifting rod 32, and a vertical guide rod is arranged between the electromagnet 31 and the vertical lifting rod, so that the vertical lifting rod 32 can drive the electromagnet 31 to move up and down, and the electromagnet 31 controls magnetic attraction through a remote controller.
Obviously, the lifting and loading and unloading actions of the magnetically attracted template can be completed through the magnetic attraction of the electromagnet 31, the position adjustment of the vertical lifting rod 32 in the height direction and the longitudinal position adjustment of the upper screw rod assembly 33.
A buffer assembly is arranged between the vertical lifting rod 32 and the electromagnet 31, and the concrete connection structure is as follows:
referring to fig. 1 and 3, the buffer assembly includes an upper plate 41 fixed to the vertical lift bar 32 and a lower plate 42 fixed to the electromagnet 31, with a gap between the upper plate 41 and the lower plate 42, and both are steel plates.
Four vertical guide rods 43 are slipped between the upper plate 41 and the lower plate 42, springs 44 which are abutted between the upper plate 41 and the lower plate 42 are sleeved on the guide rods 43, upper pull-up blocks 45 are fixed at the upper ends of the guide rods 43, the upper pull-up blocks 45 are abutted against the upper surface of the upper plate 41, lower pull-down blocks 46 are fixed at the lower ends of the guide rods 43, the lower pull-down blocks 46 are abutted against the lower surface of the lower plate 42, and the upper pull-up blocks 45 and the lower pull-down blocks 46 are nuts which are in threaded connection with the guide rods 43.
Thus, the elastic hanging connection between the upper plate 41 and the lower plate 42 allows the electromagnet 31 to hang under the vertical lift bar 32.
The main body of the electromagnet 31 is cylindrical, and the flat magnetic attraction surface faces downwards;
When the electromagnet 31 moves downwards when the magnetic attraction die is in magnetic attraction, the lower plate 42 moves upwards along the guide rod 43 when the magnetic attraction surface of the electromagnet 31 presses the die surface, so that the electromagnet 31 is prevented from excessively striking the die surface;
As the magnet iron rises, the lower plate 42 moves rapidly downward under the force of gravity and the compression spring 44 until the lower plate 42 abuts the pull-down block 46.
The spring 44 has an extrusion effect on the upper plate 41, so that the magnetic attraction surface and the surface of the die can be attached more tightly.
When the surface of the second plate body 22 is hollow after long-term use, the placed template is easy to slightly incline;
However, the electromagnet 31 moves vertically only, and the situation that the magnetic attraction surface of the electromagnet 31 is difficult to be effectively attached to the surface of the template occurs, so the following improved design is performed, and specific reference is made to fig. 4 and 5 of the accompanying drawings:

The air bag module 7 comprises an elongated air bag which is positioned on the upper surface of the middle plate 51 and is inflated, so that the lower edge of the turned template can be contacted with the air bag to buffer, and the air bag is adopted instead of a raised rubber pad, because the edge of the template can be pressed on the air bag when the template is turned, the area of the die plate can be smooth through deflation, and the magnetic attraction lifting of the die plate is facilitated.
The upper surface of the middle plate 51 is provided with a groove for accommodating the air bag, and after the air bag is exhausted, the depth of the wall thickness groove of the air bag is the same, so that the template pressed on the air bag is smoother.

referring to fig. 12, when the second plate 22 is vertical, the side baffle 95 protrudes vertically from the second plate 22 to form a side barrier;
Referring to fig. 11, the connection relationship between the rotary shaft 93, the rotary shaft 94, and the crown 910 and the shaft 911, which correspond to the plate body No. three 23 and the intermediate plate 51, is the same as the connection structure between the plate body No. two 22 and the intermediate plate 51.
Referring to fig. 12, the side guards 95 provided on the rotation shaft 94 on the third plate body 23 and the side guards 95 of the second plate body 22 are positionally staggered with each other, and when the second plate body 22 and the third plate body 23 are simultaneously vertical, the side guards 95 on the two plate bodies are alternately arranged.
The working effect is as follows:
The rotation of side shield 95 is realized in gear linkage to adopt the hydro-cylinder as pivoted power supply in this scheme, consequently the baffle force that separates of side shield 95 is great, separates that keeps off stability is better, and the template is difficult for from No. two plate body 22 and No. three plate body 23 follow roll-off in the upset in-process, and because the baffle effect of side shield 95 has also avoided staff's mistake operation to insert two plate body by the condition emergence of centre gripping, has promoted the security performance.
The side baffle 95 needs to be rotatably installed, and the purpose is that, referring to fig. 11 and 13, after a part of the mold is disassembled and needs to be cleaned, then the lifting frame 96 needs to be adopted, the upper template 101 at the position of the third plate body 23 is moved to the lifting frame 96 platform with the same height, at this time, the third plate body 23 is in the horizontal position, and the side baffle 95 needs to be located below the upper surface of the third plate body 23, so that the upper template 101 cannot be blocked from being horizontally pushed onto the lifting frame 96.
Embodiment 3 is a disassembly and assembly mechanism of an injection mold, which is different from embodiment 2 in that, referring to fig. 14, two engaged bevel gears 920 are used to realize the linkage between a rotation shaft 94 and a rotation shaft 93.
Example 4a method of operating the attaching/detaching mechanism of the injection mold of example 1, referring to fig. 15, includes the following detaching steps:
Step 1.1, lifting a die to be equal to the first plate body 21 in height by a lifting vehicle, and translating the die to the upper surface of the first plate body 21;
Step 1.2, the electromagnet 31 is attracted to the upper template 101 by descending the electromagnet 31, the die is demoulded by pulling up, and the template is transferred to the second plate 22 by the upper screw rod assembly 33;
step 1.3, inflating the air bag assembly 7, and rotating the third plate 23 for 90 degrees to a vertical state;
Step 1.4, the second plate 22 is rotated 90 degrees to a vertical state, so that the upper template 101 is rotated to a vertical state and kept stationary between the second plate 22 and the third plate 23;
step 1.5, exhausting the right air bag 72, and inclining the upper template 101 towards the third plate body 23;
Step 1.6, the third plate body 23 rotates downwards, the upper template 101 is attached to the third plate body 23 and synchronously rotates downwards until the upper template 101 is horizontally placed on the third plate body 23 and the die cavity is upwards, then the left air bag 71 is exhausted, then the second plate body 22 is turned to be horizontal, and at the moment, the die cavities of the two templates are upwards, so that rust-proof grease can be painted.
The method comprises the following installation steps, which are opposite to the disassembly steps:
Step 2.1, after the grease is coated in the step 1.6, the air bag module 7 is inflated again;
step 2.2, rotating the second plate 22 to be vertical, and then rotating the third plate 23 to be vertical;
step 2.3, exhausting the left air bag 71, firstly putting the second plate 22 flat, then exhausting the right air bag 72, and then putting the third plate 23 flat;
step 2.4, the electromagnet 31 magnetically attracts the upper template 101 on the second plate 22 and transports the upper template to the upper part of the first plate 21;
and 2.5, aligning the upper template 101 and the lower template 102 with each other through fine adjustment in the longitudinal direction and the transverse direction, and moving the upper template 101 downwards to complete die assembly.
