As shown in fig. 1, the air-cooling assembly 92: the air box 921, the blowing rod 922 and the blowing head 923; the air box 921 is fixed on the mounting frame 12, one end of the blowing rod 922 is communicated with the air box 921, and the other end of the blowing rod is communicated with the blowing head 923; the blowing head 923 is disposed downward toward the second die holder mechanism 31, thereby performing air cooling operation on the blown product.

The working principle is as follows: for convenience of illustration, according to the process, the present invention preferably installs four sets of first mold base mechanisms 21 on the pressing turntable 22, and the blowing turntable 22 installs six sets of second mold base mechanisms 31 capable of automatically opening and closing, and then circularly and precisely sends the pressed die 5 to the forming mold half 311 through the middle clamping and transferring unit 4.

The method specifically comprises the following steps: when a glass gob is cut and dripped into the first die holder mechanism 21 on the pressing and indexing unit 2, the turntable 22 of the pressing and indexing unit 2 quickly rotates the first die holder mechanism 21 containing the gob to a punching station, and at the moment, if the clamping and transferring unit 4 drives the neck mold 5 to close and descend into the cavity of the prototype half die 211, the edge of the butt edge of the neck mold 5 is clamped by the die locking mechanism 6, so that the formability of the gob in pressing is improved, the half line of a workpiece is relatively small during blowing, and the subsequent workpiece processing operation is facilitated; the stamping mechanism 7 rapidly stamps downwards to drive the outer wall of the edge pressing component 72 to be attached to the mouth mold 5, and a punch of the stamping mechanism 7 stamps into the prototype half-mold 211 to stamp the gob into a prototype blank;

the mold locking mechanism 6 releases the neck mold 5, the clamping and transferring unit 4 ascends to hang the pressed material blank on the neck mold 5 and rotates to the position above the blowing station of the blowing and indexing unit 3, the neck mold 5 rotating device descends to attach the neck mold 5 to the inner wall of the forming half mold 311 and then open the neck mold 5, the material blank punched at the opening part is left in the forming half mold 311, then the neck mold 5 rotating device ascends, and meanwhile the rotating table 33 rotates the forming half mold 311 to the next blowing station.

The blowing assembly 91 is operated, the blowing head 914 descends to press the opening ring of the blank, compressed air is introduced to blow and form the product, after the blowing time is up, the blowing head 914 retreats, the forming half-die 311 rotates to the cooling station in a closed state, and the air cooling assembly 92 fully cools the product.

And then the mold half 311 is automatically opened by rotating to the taking-out station, and the product can be taken out from the mold half 311 by a person or a mechanical hand and put on a conveyor or directly enter and exit a furnace. So as to complete the technological process from blanking to product preparation, and similarly, the pressure blowing period of the product at the next station can continuously and circularly act through a double-rotary table pressure blowing machine.

In actual application, the whole machine integrates the design principles of mechanical, hydraulic, electric and pneumatic elements and the like, and the continuity and the coordination of the actions are controlled by an industrial computer PLC program. The full-automatic control can be carried out on the glassware press-blow molding process, the complex and heavy operation of the original glassware in severe environments such as high temperature and the like is converted into intelligent operation, the working environment is obviously optimized, and the labor intensity is reduced; the operation is simple and convenient, the real-time parameter setting can be carried out on the touch screen of the control panel according to the production process requirements in the operation process, the accuracy and the rapidness of the process adjustment process are ensured, and the high coordination and the unification of the electromechanical integration are realized.

The product quality is improved: the machine is optimized and integrated on the vessel press-blowing process, and a series of process configurations are added, so that the surface process requirements of glassware are met, the grade of the product is greatly improved, the product is uniform in wall thickness after press-blow molding, free of wrinkles and the like, and good in surface glossiness effect.

The investment cost is reduced: the double-rotary-table press-and-blow machine provided by the invention integrates a set of complete process configuration to realize process requirements, not only combines the common characteristics of a rotary-table press and a rotary-table blow machine, but also greatly reduces the investment cost and labor cost of manufacturers through other auxiliary equipment such as a clamping transfer unit and the like.

The production efficiency is improved: the current pressure blowing method has the advantages that the production efficiency is low, the yield can be improved only by increasing the number of equipment, the energy loss in molding is reduced by adopting a double-turntable pressure blowing design, the molding speed is high, the production efficiency is high, and therefore, the effects in the aspects of energy conservation and material saving are remarkable.

The successful research and development of the double-rotary-table blowing press fills the blank of domestic glass mechanical equipment, promotes the development and innovation of domestic glass machinery, improves the production efficiency and quality of domestic glassware production, reduces the cost of product production, has wide market prospect, and has rich economic benefits and good social benefits when being developed and used.
