The working principle of the invention is as follows:

when the male die core 9 is placed in the male die plate 3, the second clamping plate 9-1 enters the clamping groove, along with the continuous entering of the second clamping plate 9-1, the second clamping plate 9-1 is in contact with the clamping jaws 8-42 and pushes the clamping jaws 8-42, so that the clamping jaws 8-42 drive the limiting blocks 8-43 to rotate through the rotating shafts 8-41, the limiting blocks 8-43 stretch the springs when moving in the fixed cabin, after the second clamping plate 9-1 is completely placed in the male die plate 3, the supporting jaws of the clamping jaws 8-42 are inserted into the fixed grooves, and the locking shafts 8-1 are inserted into the fixed cabin.

When the cavity insert 10 is placed in the cavity plate 4, the first clamping plate 10-1 enters the clamping groove, along with the continuous entering of the first clamping plate 10-1, the first clamping plate 10-1 is in contact with the clamping jaws 8-42 and pushes the clamping jaws 8-42, so that the clamping jaws 8-42 drive the limiting blocks 8-43 to rotate through the rotating shafts 8-41, meanwhile, the limiting blocks 8-43 stretch the springs when moving in the fixed cabin, after the first clamping plate 10-1 is completely placed in the cavity plate 4, the supporting jaws of the clamping jaws 8-42 are inserted into the fixed grooves, and the locking shafts 8-1 are inserted into the fixed cabin.

When the male die core 9 is completely placed in the male die plate 3, the lower end of the material pushing shaft 9-2 is positioned in the ejecting through groove and is contacted with the upper end of the ejector pin 7-2.

When the female template 4 is tightly contacted with the male template 3, the compression shaft 4-1 is inserted into the switching shell 7-51, the switching plate 7-52 and the switching shell 7-51 form a cooling liquid circulation channel, meanwhile, the hydraulic pump transmits cooling liquid into the mixing cabin 7-1 through a pipeline, the cooling liquid flows into the cooling pipe 3-1 through the transmission pipe 7-3 and the switching component after filling the mixing cabin 7-1, so that the male template 3 and the male mold core 9 are cooled, and the other end of the cooling pipe 3-1 extends out of the male template 3 and is connected with an external cooling mechanism.

After the product is formed, the female die plate 4 is separated from the male die plate 3, the compression shaft 4-1 is drawn out of the switching shell 7-51 and the male die plate 3, the switching plate 7-52 is restored to the original position under the action of the spring, namely the position when the compression shaft 4-1 is not contacted with the switching plate 7-52, the switching plate 7-52 is restored to the original position, then the connection between the cooling pipe 3-1 and the transmission pipe 7-3 is cut off, and cooling liquid cannot enter the cooling pipe 3-1.

When the female die plate 4 is separated from the male die plate 3 and the cooling liquid cannot enter the cooling pipe 3-1, the hydraulic pump continuously injects the cooling liquid into the mixing cabin 7-1 for a certain time, so that the pressure in the mixing cabin 7-1 is continuously increased, the cooling liquid extrudes the ejector pin 7-2 through the pressurizing cabin, the ejector pin 7-2 is lifted, the ejector pin 7-2 generates power for lifting the ejector pin 9-2 upwards, and the ejector pin 9-2 separates a product from the male die core 9 under the lifting of the ejector pin 7-2.

After taking away the product, the female die plate 4 is connected with the male die plate 3 again, the compression shaft 4-1 rotates the switching plate 7-52 again, the hydraulic pump transmits the cooling liquid into the mixing cabin 7-1 again through the pipeline, so that the cooling liquid in the mixing cabin 7-1 enters the cooling pipe 3-1 through the transmission pipe 7-3 and the switching assembly, when the cooling liquid flows into the cooling pipe 3-1 from the mixing cabin 7-1, the ejector pins 7-2 return to the original positions under the action of the springs on the material pushing shafts 9-2, and the cooling liquid in the pressure relief cabin and the pressure boosting cabin enters the mixing cabin 7-1 again.

When products with other shapes need to be produced, an operator presses the pressing shell 8-31, the pressing shell 8-31 transmits power to the pressure block 8-11 through the transmission cabin 8-32, and the locking shaft 8-1 is driven by the pressure block 8-11 to leave the fixed cabin.

When the locking shaft 8-1 rises, the short shaft slides in the self-locking slideway 8-21, the locking shaft 8-1 is locked in the self-locking slideway 8-21, when the locking shaft 8-1 is locked, the lower end of the locking shaft 8-1 is positioned above the fixed cabin, after an operator presses the pressing shell 8-31, the limiting blocks 8-43 are not limited by the locking shaft 8-1, when the operator extracts the cavity insert 10 from the cavity plate 4, the first clamping plate 10-1 drives the clamping jaws 8-42 to rotate in the fixed cabin at a certain angle under the driving of the cavity insert 10, so that the clamping jaws 8-42 are separated from the first clamping plate 10-1, and the cavity insert 10 extracts the cavity plate 4.

When an operator draws the male die core 9 out of the male die plate 3, the second clamping plate 9-1 drives the clamping jaws 8-42 to rotate in the fixed cabin at a certain angle under the driving of the male die core 9, so that the clamping jaws 8-42 are separated from the second clamping plate 9-1, the male die core 9 draws the male die plate 3, meanwhile, the limiting blocks 8-43 drive the rotating shafts 8-41 to rotate under the action of the springs, so that the clamping jaws 8-42 return to the original positions, after the male die core 9 and the female die core 10 are drawn out, the operator presses the pressing shells 8-31 again, so that the locking shaft 8-1 slides once again in the self-locking slideways 8-21, the locking shaft 8-1 is in contact self-locking, and the lower end of the locking shaft 8-1 is in contact with the upper end faces of the limiting blocks 8.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
