Specific embodiment
With reference to the accompanying drawing, detailed description of the present invention specific embodiment.
Injection blow molding machine injection molding as shown in Figure 1 and blow molding open mold synchronization mechanism, including being connected on injection blow molding machine crossbeam 1
Mould oil cylinder 2 is opened and closed, 201 one end of open mold cylinder putter of folding mould oil cylinder 2 is stretched out outside crossbeam 1, and open mold cylinder putter 201
Portion is connected with a connecting rod 3, and the open mold cylinder putter 201 is connected to 3 middle part of connecting rod, 3 both ends of connecting rod be connected separately with
The blow molding pull rod shaft 4 disposed in parallel of open mold cylinder putter 201 and injection molding pull rod shaft 5, the blow molding pull rod shaft 4 and injection molding are drawn
Bar axis 5 is slidably connected at respectively on crossbeam 1, and the other end of blow molding pull rod shaft 4 passes through crossbeam 1 and connect with blow molding moving template 6, is infused
The other end of modeling pull rod shaft 5 passes through crossbeam 1 and connect with injection molding moving template 7.
Above-mentioned injection blow molding machine injection molding opens and closes the movement of 2 drive link 3 of mould oil cylinder with blow molding open mold synchronization mechanism when in use,
Connecting rod 3 drives blow molding pull rod shaft 4 and injection molding pull rod shaft 5 to move synchronously, and blow molding pull rod shaft 4 and injection molding pull rod shaft 5 drive blow respectively
Modeling moving template 6 and injection molding moving template 7 move synchronously, to realize the synchronous on-off of blow mold and injection mold.
Two guide posts 9 for being parallel to open mold cylinder putter 201, the distribution of two guide posts 9 are fixedly installed on the crossbeam 1
