The half components 12 are two components and are respectively arranged on two end parts of the connecting frame 13. The two end parts of the connecting frame 13 are respectively provided with a half component 12 and a half component 12, the die components 2 on the two sides of the frame 1 are respectively set as a die component 2 and a die component 2, and the bottle blowing machine normally operates, taking a certain time as an initial state as an example: assuming that the first mold assembly 2 completes the bottle blowing operation and the injection mold assembly completes the injection molding operation, firstly, the injection mold assembly is opened, and the connecting plate is driven by the upper mold plate 10 to be lifted upwards, so that the first half assembly 12 drives the bottle blank to be separated from the injection molding and bottle blowing mold cavity by clamping the bottle opening, and meanwhile, the second half assembly 12 moves upwards and is separated from the second mold assembly 2; then, the connecting plate moves horizontally, so that the half component 12 with the bottle blank moves to the upper part of the die component 2, and meanwhile, the half component 12 moves to the area between the upper die plate 10 and the lower die plate 11; then, the injection molding assembly is closed, the connecting plate is driven by the upper mold plate 10 to descend downwards, so that the second half assembly 12 is clamped by the upper mold plate 10 and the lower mold plate 11 to form an injection molding and bottle blowing mold cavity, and meanwhile, the first half assembly 12 drives the bottle blank to fall to a bottle blowing station; and finally, the injection molding mechanism performs injection molding operation on the injection molding and bottle blowing mold cavity clamped with the second half component 12, and the bottle blowing mechanism performs compensation heating operation and bottle blowing operation on the bottle blank carried by the first half component 12 in sequence. By alternately and circularly implementing the operations on the first half component 12 and the second half component 12, the first half component 12 and the second half component 12 alternately move to an injection molding mechanism to obtain bottle blanks, and further, the bottle blanks are alternately conveyed to the corresponding mold components 2 to implement compensation heating operation and bottle blowing operation.
Example eight:
compared with the seventh embodiment, the present embodiment provides another specific structure of a bottle blowing machine.
As shown in fig. 7, at least two sets of mold assemblies 2 are disposed on the side of the frame 1, and the side mold plates 5 are switched to open and close along the translation direction of the engagement frame 13. Specifically, the opening and closing direction of the side template is consistent with the opening and closing direction of the mold component 2, the arrangement space required by the mold component 2 is effectively reduced, and the bottle blank can be conveniently conveyed and transferred between the injection molding mechanism and the bottle blowing mechanism.
In this embodiment, the tip that links up frame 13 is equipped with the half subassembly 12 that corresponds with 1 unilateral mould subassembly 2 quantity in frame, and the mechanism of moulding plastics can form the bottle base that satisfies 1 unilateral mould subassembly 2 bottle blowing in frame required by single processing, and the quantity through increasing single injection moulding and bottle blowing promotes machining efficiency.
Example nine:
compared with the first to eighth embodiments, the present embodiment provides another specific structure of a bottle blowing machine.
In this embodiment, at least two bottle blowing mold cavities are arranged in the mold component 2, when the mold is closed, the mold component 2 encloses to form at least two mutually independent bottle blowing mold cavities, the number of the bottle blowing mold cavities of a single group of mold components 2 is increased to increase the number of single bottle blowing, and the bottle blowing efficiency is sequentially improved.
In this embodiment, the heating assembly 4 includes heating portions 7 corresponding to the number of the bottle blowing cavities, so that each bottle blank can be heated complementarily. In addition, the part of the heating part 7 can be controlled to positively compensate and heat the bottle blank with lower temperature according to the requirement, and the bottle blank with higher temperature is not compensated and heated, so that the temperature of each bottle blank is ensured to meet the blowing requirement, and the energy consumption is reduced by reducing the operation of the heating part 7.
