When installing case 10 drives piston rod 7 through second connecting rod 5 and moves down, can make piston 18 in the inside downstream of water tank 6, thereby can crowd two arc covers 19 with the inside cooling water of water tank 6 through pipeline two 17 and constitute closed chamber, realize the storage, after the cooling water flows into cold chamber, through piston rod 7 rebound, can cool off the cooling water suction water tank 6 of cold intracavity through pipeline one 15, in order to be ready for next use, thereby realized the water-cooling effect of circulation.

Further, the time delay design includes groove seat 31, and groove seat 31 fixed connection is at the outer wall of left mould 2, and the mounting groove has been seted up to the outer wall that left mould 2 was kept away from to groove seat 31, and the inner wall sliding connection of mounting groove has articulated seat, fixedly connected with spring 32 between the interior bottom of articulated seat and mounting groove, notch 33 has all been seted up to the outer wall around groove seat 31, outer wall fixedly connected with gag lever post 34 around the articulated seat, the outer wall of gag lever post 34 and the inner wall sliding connection of notch 33.

Through the cooperation of gag lever post 34 and notch 33, realize fixed and spacing, through setting up spring 32, for going up mould 11 and continue to move down and provide time, provide the buffering of certain degree simultaneously.

Further, the inner wall of the upper die 11 is fixedly connected with two mounting blocks 20, the outer walls of the opposite surfaces of the two mounting blocks 20 are provided with flow slowing surfaces, the inner bottom of the first pipeline 15 facing the cold cavity is provided with a pressurizing nozzle, and the nozzle of the pressurizing nozzle is close to the inner bottom.

Through setting up the slow flow face, for the cooling water provides the inclined plane, make things convenient for it to get into cold chamber, prevent simultaneously that there is water to stay, the design of pressure nozzle is for taking away cooling water from cold chamber more effectually in addition.

Further, the second pipe 17 and the first pipe 15 are stretchable corrugated hoses, are easy to install and replace, and are prevented from being broken when moved, and the use is affected.

Furthermore, the cooperation of twice demolding has the cooperation, all contradicts finished bottom and outer wall, makes the finished quality protected, prevents that the drawing of patterns from tearing and warping, and simultaneously with the finished jacking ejection of compact, has made things convenient for the staff, has also protected the staff.

Through the cooperation of above-mentioned isotructure, realized twice drawing of patterns after the shaping, better to having protected finished product mould and drawing of patterns effectual, reached circulating water cooling's effect simultaneously, prevent to go up mould 11 and after cold and hot alternation and long-time use, cause the damage of mould, reach dynamic balance's circulating water cooling.

The working principle is as follows: when the integrated plastic compression molding die is used, the multi-stage hydraulic cylinder 8 is started to output the integrated plastic compression molding die step by step, the first telescopic rod 13 drives the installation box 10 and the upper die 11 to move downwards, the first connecting rod 4 and the upper die 11 move synchronously, the left die 2 and the right die 12 are close to each other and are closed due to the hinged relation of the first transmission rod 3, when the left die 2 and the right die 12 are close to each other, the installation seat 27 can move downwards through the hinged relation of the second transmission rod 26, the push plate 14 is pulled downwards through the blunt spring 28 and the third connecting rod 30, due to the existence of the blunt spring 28, the contact time of the push plate 14 and the left die 2 and the right die 12 is earlier than the closing time of the left die 2 and the right die 12, along with the continuous close of the left die 2 and the right die 12, the push plate 14 can be kept at the same position, when the left die 2 and the right push plate 12 are closed to form a lower die, and the inner bottom of the lower die 14 is completely attached, the inner bottom of the lower die is closed, and the molten plastic is injected into the lower die at the moment.

When the upper die 11 moves downwards, the piston rod 7 is driven to move downwards, so that cooling water in the water tank 6 is squeezed into a closed cavity formed by the two arc-shaped covers 19 and the mounting plate 21 through the second pipeline 17.

Control first telescopic link 13 and continue the downward output, thereby make last mould 11 compress melting down, make its laminating mould inner wall, realize the design, when last mould 11 is in the forming state, keep the position of first telescopic link 13, make second telescopic link 25 export downwards, because the articulated relation of round pin axle 24 and two arc covers 19, rack 22 and arc rack 23's meshing relation, make the closed chamber that can make two arc covers 19 and mounting panel 21 to constitute when second telescopic link 25 moves down open, two arc covers 19 all upwards rotate along round pin axle 24 promptly, thereby make the cooling water in the closed chamber to the cold chamber of going up mould 11 inside, thereby make last mould 11 and the contact surface cooling that melts to mould, the auxiliary forming.

After the cooling water is released, the second telescopic rod 25 is input upwards, the mounting plate 21 is moved upwards synchronously, and the arc-shaped cover 19 rotates downwards along the pin shaft 24 and then closes with the position of the pin shaft 24 after the arc-shaped cover moves upwards.

After the forming, the first telescopic rod 13 is upwards input to drive the installation box 10 and the upper die 11 to upwards move, so that the upper die 11 and the lower die are separated, due to the fact that the time delay mechanism is designed, the upper die 11 firstly upwards moves, elastic potential energy stored in the spring 32 is firstly consumed, then the upper die 11 continuously upwards moves, the left die 2 and the right die 12 are mutually far away through the two first transmission rods 3, and therefore the first-step demoulding is completed.

When left mould 2 and right mould 12 kept away from each other, through two second transfer lines 26 make mount pad 27 upwards remove to make push pedal 14 rebound, upwards carry out the drawing of patterns and ejecting lifting for the second time to the finished product when push pedal 14, accomplish drawing of patterns and ejection of compact, the cooperation of twice drawing of patterns makes the product not fragile and drawing of patterns effectual.

Similarly, when installing case 10 moved up, can drive piston rod 7 rebound to make piston 18 rebound, thereby with the inside of the water suction water tank 6 of cold chamber, through holistic cooperation, make water tank 6, pipeline two 17, closed chamber, cold chamber, pipeline one 15 and water tank 6 form circulation circuit, and can be to realizing automatic cyclic utilization.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
