The specific realization principle is as follows: when the plastic film extrudes a certain position downwards through the blowing pipe 4 when using, the plastic film is wrapped up by the die closing plate 5 in the set time by mutual buckling, thereby realizing the film blowing of the plastic die, but when the plastic film is buckled, the die closing plate 5 is easy to move out of step in the process of moving back and forth because of the mechanical movement, thereby leading to the upper and lower dislocation phenomenon of two bonding symmetrical surfaces of the formed plastic die, simultaneously, the side seam of the plastic film is unevenly stressed because of the dislocation die closing, and the plastic film can present uneven thickness of the film material near the side seam bonding part under the action.

Therefore, when the mold closing plate 5 transversely moves to approach the mold closing plate, the magnetic groove 1a6 and the magnetic buckle plate g are mutually buckled by utilizing the principle of magnetic force, when the preset Y axis of the equipment moves, because the two mold closing plates 5 are both connected with the magnetic groove 1a6, the regulating rod 1a5 connected with the magnetic groove 1a6 forms an instantaneous 45-degree angle at one end, and the direction of the anticlockwise 135-degree angle at the other end is buckled and connected with the Y-axis track of the field track 1a2, the mold closing plate 5 is enabled to synchronously move, and because the right-angle buckle 1a42 performs a limiting function with the partition plate 1a43 through the regulating spring 1a44 at the clockwise 135-degree angle of the X axis, the mold closing plate 5 can be perfectly buckled, so that the vertical staggering of the plastic film blowing caused by the asynchronous motion of the mold closing plate 5 is avoided.

Meanwhile, the heating strip 6a2 is electrified and heated, so that the heat inside the strip frame 6a1 is improved, the strip frame 6a4 is high in heat under the action of 6a4, the strip plate 6a4 moves back and forth under the action of the driving belt 6a3, and the plastic hot melt extruded during blow molding and die closing is smoothed by the film layer 6a5, so that the plastic hot melt can be semi-fluid and flows back to the sewing side of the blow mold, and the edge seam of the plastic hot melt can be uniformly processed in a thin and thick mode.

The invention solves the problem that in the prior art, because the prior art is in mechanical motion during the process of moving back and forth, the existing die closing plate is easy to move asynchronously, so that the two bonding symmetrical surfaces of the formed plastic die are staggered up and down, and simultaneously, because of the staggered die closing, the edge seams of the plastic film are stressed unevenly, and the plastic film can present uneven thickness of the film material close to the bonding positions of the edge seams under the action of the plastic film, through the mutual combination of the components, the invention utilizes the mutual matching of the anti-overflow edge structure and the uniform pushing structure to realize heating type uniform heating treatment on the die edge material generated by pressing, thereby pushing the film thickness of the die edge material, so as to avoid the phenomenon that the sewing edge of the die after the blow molding is uneven thickness, and further influence the normal use of the die, and utilizes the self-reverse torsion piece to be buckled with the two die closing plates through the magnetic attraction principle, under the action that the restricting rod is rotated by 45 degrees, the mold closing is synchronously pushed, so that the phenomenon that finished products are connected in a staggered mode due to asynchronous mold closing generated during movement is avoided, and the inferior manufacturing of the mold is increased.
