Before the plastic product is manufactured, a user firstly injects gas between the right side of the extrusion plate 1101 and the fixing piece 109, the one-way valve on the right side of the fixing piece 109 is in an open state in the gas injection process, after the right part in the fixing piece 109 is filled with gas, the user stops injecting gas into the fixing piece 109, and then the one-way valve on the right side of the fixing piece 109 is closed.
When a plastic product needs to be manufactured, a user controls the electric sliding rail 103 through the control terminal 102 to drive the first sliding frame 104, the second sliding frame 106 and parts on the second sliding frame 106 to move rightwards, the first sliding frame 104, the U-shaped sliding rod 110 and the extrusion plate 1101 are accompanied with the second sliding frame 106 to move rightwards, in the process that the extrusion plate 1101 moves rightwards, two one-way valves which are distributed in a mirror image mode are in an opening state, the one-way valves on the right side of the fixing piece 109 are in a closing state, the pressure release valve in the L-shaped air inlet cavity 1081 is in a closing state, when the extrusion plate 1101 moves rightwards along the fixing piece 109 through opening of the one-way valve on the extrusion plate 1101, gas on the right part of the fixing piece 109 is transferred to the left part of the fixing piece 109, and after the extrusion plate 1101 slides to a limiting position, the right side of the first fixing ring 1051 is attached to the left side of the static die 108, the electric sliding rail 103 does not drive the second sliding frame 106 and the parts on the extrusion plate 1101 to move, and the two one-way valves on the extrusion plate 1101 are in a closing state.
After the right side of the first fixing ring 1051 is attached to the left side of the stationary mold 108, injection molding can be started (injection molding is a common plastic processing technology, molten plastic is injected into the mold to form a required shape and size in the mold), a gap exists between the movable mold 105 and the stationary mold 108, the gap is the shape of a plastic product after injection molding is completed, at this time, liquid material is injected into the gap between the movable mold 105 and the stationary mold 108 through two feeding pipes 111 until the gap between the movable mold 105 and the stationary mold 108 is completely filled by the liquid material, and after the gap between the movable mold 105 and the stationary mold 108 is completely filled, a user does not inject the liquid material into the movable mold 105 and the stationary mold 108 through two feeding pipes 111, and after the liquid material between the movable mold 105 and the stationary mold 108 is solidified, the plastic product after injection molding is completed.
When the injection molded plastic product is required to be taken out between the driven mold 105 and the static mold 108, the user manually rotates the driven mold 105 back and forth, so that the outer side of the driven mold 105 is separated from contact with the inner wall of the plastic product, the later removal of the driven mold 105 is facilitated, then the user controls the electric sliding rail 103 through the control terminal 102 to drive the first sliding frame 104 and parts thereon to move leftwards, and the driven mold 105 is gradually separated from contact with the plastic product along with the leftward movement of the first sliding frame 104 (the reason that the driven mold 105 is separated from contact before the plastic product is due to the fact that before the plastic product is injected, the user firstly smears a layer of anti-sticking agent on the outer side of the driven mold 105 due to the manufacturing procedure of the plastic product, so that the driven mold 105 can be easily removed in the process of removing the plastic product.
After injection molding is completed, the second sliding frame 106 drives the extrusion plate 1101 and the U-shaped sliding rod 110 to move leftwards, and the gas at the left side of the fixing piece 109 is extruded in the process that the U-shaped sliding rod 110 moves leftwards, so that the gas at the left side of the fixing piece 109 is gradually compressed, when the pressure at the left side of the fixing piece 109 is larger than the bearing range of the pressure release valve in the L-shaped air inlet cavity 1081, the pressure release valve in the L-shaped air inlet cavity 1081 is opened, so that the gas at the left side in the fixing piece 109 is instantaneously fed between the static mold 108 and the plastic product through the surrounding L-shaped air inlet cavity 1081, the plastic product is jacked to the left side from the static mold 108 through the gas between the static mold 108 and the plastic product, and the effect of automatically demolding the plastic product is achieved, and when the pressure of the gas in the fixing piece 109 is smaller than the pressure born by the pressure release valve in the adjacent L-shaped air inlet cavity 1081, the pressure release valve in the L-shaped air inlet cavity 1081 is closed accordingly.
In the process of moving the squeeze plate 1101 leftwards, the two check valves in the squeeze plate 1101 are in a closed state, at this time, the squeeze plate 1101 moves leftwards to generate suction force, so that the check valve at the right part of the fixing piece 109 is opened, external air enters the fixing piece 109 from the right part of the fixing piece 109, the effect of inflating the right part of the fixing piece 109 is achieved, and after the squeeze plate 1101 stops moving, the check valve at the right part of the fixing piece 109 is closed to seal the right part of the fixing piece 109.
When the second carriage 106 and its upper parts have been moved to the base position, as shown in fig. 1, the outer side of the movable mold 105 is out of contact with the inner side of the plastic product, and the right part of the plastic product is still located in the stationary mold 108, so that the user can take out the plastic product from the stationary mold 108.
