when the injection molding liquid inside the molding groove 403 is filled, the liquid is suddenly filled, upward thrust is generated on the cambered surface matching pipe 605, meanwhile, under the double upward acting force of buoyancy of the injection molding liquid, the injection molding liquid pushes the cambered surface matching pipe 605 out of the injection molding hole 402, at the moment, the injection molding hole 402 is not subjected to the limiting effect of the cambered surface matching pipe 605, namely, the whole of the half mold 401, the mold fixing ring 202, the sliding block 305 and the vertical limiting block 304 is not subjected to the limiting effect, at the moment, the compressed vertical limiting block groove 302 pushes the whole formed by the half mold 401, the mold fixing ring 202, the sliding block 305 and the vertical limiting block 304 to the rotation direction of the annular rotation supporting plate 201, the cambered surface matching pipe 605 is separated from the upper part of the injection hole 402 at the moment of being pushed out from the injection hole 402, the cambered surface matching pipe 605 is prevented from being clamped into the injection hole 402 again, it is noted that in the process of injecting injection liquid into the forming groove 403 by the cambered surface matching pipe 605, the annular rotating support disc 201 needs to keep thrust to balance the deformation restoring force of the spring 303 all the time, the phenomenon that the cambered surface matching pipe 605 cannot be separated from the injection hole 402 quickly after injection is prevented from being restored before the injection is completed, the injection-completed mold continues to move along with the annular rotating support disc 201 to a cooling area, water from the outside at the water inlet pipe 701 impacts and cools the outer side wall of the mold, an atomizing nozzle can be additionally arranged at the water inlet pipe 701 to increase the contact area of the water and the mold, so that the cooling effect is better, the cooling water is collected by the cooling tank 102 and directly performs heat dissipation and cooling in the cooling tank 102, utilize the water pump to take out after the water temperature cooling and continue to drop into the mould cooling operation, the mould that the cooling was accomplished rotates to the operating region along with cyclic annular rotation support plate 201, and the staff takes out the shaping product at the operating region to in reinstalling mould retainer plate 202 with half mould 401, the in-process of installation should be noted and insert locating piece 405 in the constant head tank 203.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
