[0025] The rear of the mold main body 10 is lap-connected with the magnetic chuck 11, the inside of the magnetic chuck 11 is fixedly connected with the electromagnet 12, the rear of the magnetic chuck 11 is fixedly connected with the buffer spring 13, the buffer spring 13 is provided with three groups, wherein each group is provided with five buffer springs 13, and the five buffer springs 13 are arranged in sequence from top to bottom, the inner wall of the inner seat body 14 is fixedly connected with the fixed rod 15, the outer wall of the fixed rod 15 is fixedly connected with the shock absorbing spring 16, the rear of the shock absorbing spring 16 is lap-connected with the sliding sleeve 17, the shock absorbing spring 16 and the sliding sleeve 17 are directly connected, the inner wall of the sliding sleeve 17 is lap-connected with the roller 18, the bottom of the sliding sleeve 17 is fixedly connected with the connecting block 19, and the sliding sleeve 17 is connected with the magnetic chuck 11 through the connecting block 19;

[0026] The rear of the jig body 1 is fixedly connected with a first pedestal 20, the outer wall of the first pedestal 20 is connected with a transverse cover 21, the inside of the transverse cover 21 is fixedly connected with a first driver 22, the outer wall of the first driver 22 is connected with a first lead screw 23, the outer wall of the first lead screw 23 is movably connected with a first sleeve 24, the inner wall of the first sleeve 24 is provided with threads, and the threads can be threadedly engaged with the outer wall of the first lead screw 23, the rear of the transverse cover 21 is fixedly connected with a second pedestal 25, the first pedestal 20 and the second pedestal 25 are the same shape, and both are provided with two groups of connecting rods on the rear side, the volume of the second pedestal 25 is greater than that of the first pedestal 20, the rear of the second pedestal 25 is fixedly connected with a second sleeve 26, the inner wall of the second sleeve 26 is connected with a second lead screw 27, the top of the second lead screw 27 is connected with a second driver 28, and the outer wall of the second driver 28 is connected with a longitudinal cover 29.

[0027] Preferably, the assembly mechanism is composed of the jig body 1, the fixed seat 2, the reinforcing rod 3, the hydraulic cylinder 4, the hydraulic push rod 5, the assembly plate 6, the pressure sensor 7, the wear-resistant layer 8, the touch panel 9 and the mold body 10. The existing manual assembly jig has low efficiency and poor fastening control. By setting the assembly mechanism, the extrusion force of the assembly plate 6 on the mold material can be set first, and then the touch panel 9 is controlled to start the hydraulic cylinder 4, so that the hydraulic push rod 5 is driven to extend, and the assembly plate 6 contacts and extrudes the mold body 10, and the pressure sensor 7 detects the extrusion force. When the extrusion force reaches the set value, the hydraulic push rod 5 stops extending and the assembly plate 6 stays at that position, so that the mold body 10 can be quickly assembled and limited by the assembly plate 6. At the same time, the reinforcing rod 3 connects and reinforces the jig body 1 and the fixed seat 2, and forms a stable triangular structure between the three, which greatly improves the carrying capacity of the fixed seat 2. The wear-resistant layer 8 has excellent wear resistance and can better protect the assembly plate 6, thereby greatly reducing the wear rate of the assembly plate 6. The mechanism not only realizes automatic clamping assembly, but also adjusts the size of the clamping force according to the material of the mold, thereby improving the practicality of the device.

[0028] Preferably, the discharge mechanism is composed of the magnetic suction disc 11, the electromagnet 12, the buffer spring 13, the inner side seat body 14, the fixed rod 15, the shock absorbing spring 16, the sliding sleeve 17, the roller 18 and the connecting block 19. In the prior art, the mold needs to be manually pushed and installed when assembling, and the position of the mold needs to be repeatedly adjusted by the travelling crane, which is very inconvenient to use. By setting the discharge mechanism, the mold can be first hung in front of the jig by the travelling crane and the lifting rope, and then the electromagnet 12 is powered on to generate magnetism through the effect of electricity generating magnetism, so as to attract the mold main body 10 through the electromagnet 12. By gradually increasing the current, the magnetism of the electromagnet 12 is gradually increased, so that the mold main body 10 is gradually attracted to the electromagnet 12 and the magnetic suction disc 11 under the action of magnetic force. When the current increases to a certain extent, the mold main body 10 can be attached to the magnetic suction disc 11. When the two are attached and collide, the shock of the magnetic suction disc 11 can be buffered by the buffer spring 13, thereby reducing the impact vibration of the magnetic suction disc 11. At the same time, the magnetic suction disc 11 can drive the sliding sleeve 17 to slide. Since the sliding sleeve 17 is directly connected with the shock absorbing spring 16, the movement of the sliding sleeve 17 can be buffered by the shock absorbing spring 16, so that the repeated movement (due to the bouncing of the buffer spring 13) of the magnetic suction disc 11 can be inhibited, thereby speeding up the stability of the magnetic suction disc 11. The mechanism can automatically adsorb and discharge the mold without manual operation, thereby reducing the work intensity of the workers and buffering the impact vibration caused by the mold, thereby improving the practicability of the device.

[0029] Preferably, the adjusting mechanism is composed of the first seat 20, the transverse cover 21, the first driver 22, the first lead screw 23, the first sleeve 24, the second seat 25, the second sleeve 26, the second lead screw 27, the second driver 28 and the longitudinal cover 29. The existing assembly jig cannot drive the mold to adjust the position and cannot assist the mold to quickly align. By setting the adjusting mechanism, after installation is completed, the first driver 22 can be started to drive the first lead screw 23 to rotate. Since the threads of the first lead screw 23 and the threads of the first sleeve 24 are engaged with each other and the first sleeve 24 is limited by the first seat 20 and cannot rotate, the first sleeve 24 can move transversely on the outer wall of the first lead screw 23 through threaded transmission, thereby driving the first seat 20 to move transversely, so that the jig main body 1 and the mold main body 10 can be transversely adjusted. Similarly, the second lead screw 27 can drive the second sleeve 26 and the second seat 25 to move longitudinally, thereby driving the jig main body 1 and the mold main body 10 to move longitudinally. The mechanism can drive the mold to adjust the position, so that the mold can be closed more quickly and accurately, thereby improving the practicability of the device.

[0030] Working principle: in the use of the injection molding automatic assembly fixture, first make electromagnet 12 power on, through the electromagnet 12 to the mold body 10 is attracted, when the current increases to a certain extent, can make the mold body 10 and magnetic chuck 11 paste, through the buffer spring 13 to the vibration of magnetic chuck 11 buffer, thereby reducing the impact vibration suffered by the magnetic chuck 11, through the touch panel 9 to start the hydraulic cylinder 4, make it drive hydraulic push rod 5 to advance elongation, and then make the assembly plate 6 contact and extrude the mold body 10, at the same time make the pressure sensor 7 to detect the extrusion force, when the extrusion force reaches the set value, can make the hydraulic push rod 5 stop elongation, can through the assembly plate 6 to the mold body 10 is equipped with fast assembly limit, after installation, can start the drive 22, make it drive the first screw 23 to rotate, make the first sleeve 24 through the thread transmission in the outer wall of the first screw 23 to move horizontally, thereby driving the first pedestal 20 to move horizontally, can make the fixture body 1 and the mold body 10 to carry on the horizontal position adjustment, similarly can through the second screw 27 drive the second sleeve 26 and the second pedestal 25 to move longitudinally, and then drive the fixture body 1 and the mold body 10 to carry on the longitudinal position adjustment, any content not described in detail in the description belongs to the prior art known to those skilled in the art.

[0031] Although the present application has been described in detail with reference to the foregoing embodiments, technical solutions recorded in the foregoing embodiments can be modified or some technical features can be replaced by equivalent ones by those skilled in the art, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
