The working principle is as follows:
when the device needs to be used, a worker installs the fixed die base 1 and the movable die base 3 on the injection molding machine respectively and connects the fixed die base and the movable die base with corresponding mechanisms on the injection molding machine, then connects the demolding telescopic column 17 with a demolding oil cylinder of the injection molding machine, connects the telescopic column 22 with a body of the injection molding machine, and then can use the injection molding die to perform injection molding and demolding work of the die;
when the injection molding machine drives the movable mold base 3 and the movable mold 4 to carry out mold closing work, the demolding oil cylinder is controlled to start working at the same time, the demolding oil cylinder drives the demolding telescopic column 17 to extend out, so that the demolding telescopic column 17 pushes the demolding support 10 to start moving, and the boss type adjusting seat 11 is completely inserted into the boss type demolding airflow groove 7, so that the sealing cushion 9 in the sealing groove 8 seals the air jet hole I13, meanwhile, the demolding support 10 and the movable mold 4 are sealed through the high-temperature-resistant sealing gasket 12, at the moment, the movable mold 4 is firstly in a closed state, then the movable mold 4 and the movable mold 4 are driven by the injection molding machine to move, the movable mold 4 and the fixed mold 2 are closed, so that the mold closing work is finished, and in the process of film closing work of the movable mold 4 and the fixed mold 2, when the movable mold 4 moves for a certain distance, at the moment, the telescopic column 22 is under the tensile force of the injection molding machine, the telescopic column 22 is gradually drawn out of the compressed air cylinder 20, the compressed piston 21 is driven to move, then, through the use of the one-way air valve I24 and the one-way air valve II 26, outside air enters the drying box 27 through the air inlet pipe 2, is dried through the drying agent 28 and then enters the compressed air cylinder 20 through the air suction pipe 25, after the film combination work is finished, the telescopic column 22 stops extending, and at the moment, the air suction work to the outside is finished inside the compressed air cylinder 20;
when the injection molding machine finishes injection molding work and controls the fixed mold 2 and the movable mold 4 to open the mold, the movable mold base 3 and the movable mold 4 are driven by the injection molding machine to move along with the injection molding machine, so that the fixed mold 2 and the movable mold 4 are separated, meanwhile, the plastic part is adsorbed on the movable mold 4 and moves along with the movable mold 4, after the movable mold 4 moves for a certain distance, the telescopic column 22 is pushed by the body of the injection molding machine and starts to be inserted into the compressed air cylinder 20, the compressed air in the compressed air cylinder 20 is compressed by the compressed piston 21, so that the air enters the high-temperature-resistant hose 30 through the air outlet pipe 23, then is injected into the second air vent 14 through the air injection communicating pipe 15 and the air injection short pipe 16 and then is injected into the first air vent 13 through the second air vent 14, when the telescopic column 22 starts to be inserted into the compressed air cylinder 20, the injection molding machine controls the demoulding oil cylinder to start to contract, so that the demoulding telescopic column 17 starts to contract, the demolding telescopic column 17 drives the demolding support 10 and the boss type adjusting seat 11 to begin to contract, a certain closed space is formed among the boss type demolding airflow groove 7, the boss type adjusting seat 11 and the plastic part, the boss type adjusting seat 11 moves to enable the first air injection hole 13 to be separated from the sealing cushion, and the first air injection hole 13 is in an open state, so that air in the compressed air cylinder 20 is injected into the closed space formed among the boss type demolding airflow groove 7, the boss type adjusting seat 11 and the plastic part through the first air injection hole 13, the air cannot directly impact the surface of the plastic part through the shape of the boss type demolding airflow groove 7 and the direction of the air injected through the first air injection hole 13, and meanwhile, the boss type demolding airflow groove 7 reflects and reduces the speed of the air flow, so that the air is slowly injected into the closed space;
along with the continuous removal of movable mould 4, the air quantity in the airtight space increases gradually for atmospheric pressure risees gradually, and after movable mould 4 opened completely, the inside atmospheric pressure of airtight space was higher than certain degree this moment, makes to mould the pressure of piece through the air and separates with movable mould 4, thereby makes to mould to drop from movable mould 4, accomplishes drawing of patterns work, and the inside compressed air of airtight space then gives off in the air.
This device adopts at the inside airtight space of a plurality of local of formation of mould for traditional injection mould, the pressure that utilizes the air makes and moulds the piece and separates with movable mould 4, thereby reach drawing of patterns effect, the use of thimble has been avoided, the effectual area of contact who improves demoulding mechanism and mould the piece, reduce the pressure that moulds a part and receive, make and mould the piece and can not take place to damage, warp, the effectual quality of moulding the piece of having guaranteed, simultaneously this injection mould internal demoulding mechanism's power source and movable mould 4's removal, the effectual staff's control that has made things convenient for, the condition of having avoided using external air supply takes place, operation sparingly.
In the operation process of the device, the drying agent 28 in the drying box 27 is used, so that the generation of water vapor in the movable mold 4 can be avoided, the influence on the plastic part is avoided, and the normal operation of the demolding operation is ensured.
In this device, flexible post 22 is connected with the organism of injection molding machine, in order to avoid moving mould 4 when removing, flexible post 22 drives compression piston 21 and moves mould 4 and carries out the synchronous motion, flexible post 22 can set up certain slip allowance with the organism of injection molding machine and be connected the position, make mould 4 in the die sinking in-process, move mould 4 and remove one section distance back, flexible post 22 just drives compression piston 21 and removes, when moving mould 4 stop moving, flexible post 22 stop moving this moment, make mould 4 at the closed membrane in-process, move mould 4 and remove one section distance after, flexible post 22 just drives compression piston 21 and removes, when moving mould 4 stop moving, flexible post 22 stop moving this moment, thereby the atmospheric pressure of drawing of patterns in-process air is too high and lead to the condition emergence of air flow rate too fast, in order to avoid producing the influence to moulding.
The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
