A plastic product forming apparatus for preventing generation of bubbles according to claim 1, wherein a feed port (20) is provided on the left side of the first casing (19), the feed port (20) is communicated with the inside of the first casing (19), and a valve is installed on the feed port (20).
9. A production method using a bubble-preventing plastic article molding apparatus according to any one of claims 1 to 8, characterized by comprising the steps of:
step one: when the plastic solution box is used, firstly, plastic solution is put into the first box body (19) through the feed inlet (20), then, the valve of the feed inlet (20) is closed, and after the first box body (19) is completely sealed, the air cylinder (5) is started;
step two: the air cylinder (5) is started to enable the pressing plate (6) to move downwards, the telescopic rod (9) drives the sliding block (30) to move downwards, when the sliding block (30) moves downwards to the lower ends of the two wedge-shaped blocks (29), under the action of restoring force of the two restoring springs (27), the two wedge-shaped blocks (29) which move transversely are close to each other, the lower surface of the wedge-shaped blocks (29) is in contact with the upper surface of the sliding block, the sliding block (30) is limited, the sealing plate (21) is driven to move downwards by the downward movement of the sliding block (30) through the connecting rod (10), and the blocking plate (18) is driven to move downwards by the downward movement of the pressing plate (6) through the second pressing rod (8), so that solution entering the third box (13) after pressurization automatically enters the injection molding box (14) under the action of pressure and self gravity and enters the injection molding work;
step three: the lower die plate (16) is pressed down by the upper die plate (15) through the pressurizing action of the sealing plate (21) until the compression spring (17) is completely compressed, and injection molding is realized after cooling;
step four: the cylinder (5) can drive the clamp plate (6) upward movement, drives the upper die plate (15) upward movement through first depression bar (7), releases the extrusion to lower bolster (16), makes lower bolster (16) upwards bounce through the effect of a plurality of compression springs (17), makes things convenient for the ejecting of lower bolster (16), takes out the product of shaping from the product outlet.
