The driving part of existing bottle blowing device is arranged on rack, leading to complex structure, relatively large volume. The utility model includes rack and the mould assembly, driving assembly and bottle blowing assembly being arranged on rack, mould assembly includes two templates of open-close action, rack includes two parallel vertical square frames and the positioning rod being arranged between the corresponding end edge of frame, driving assembly includes the driving part being fixed on positioning rod and the transmission part being connected between driving part and corresponding template, the template driven by driving assembly is folded towards and is enclosed to form the mould cavity for bottle blowing. The frame connected by positioning rod is arranged, and the driving part driving template movement is arranged on positioning rod, which not only saves fixed plate and simplifies bottle blowing device structure, but also sets driving assembly in mould assembly, drives template opening and closing switching, effectively utilizes the space between frame, reduces equipment volume, facilitates transportation and use.

Claims

1. A bottle blowing device with a positioning rod and a driving part, comprising a frame (1), a mold assembly, a driving assembly and a bottle blowing assembly arranged on the frame (1), the mold assembly comprising two mold plates (2) which can be opened and closed, the frame (1) comprising two parallel square frames (3) arranged vertically and a positioning rod (4) arranged between the corresponding end edges of the square frames (3), characterized in that, The driving assembly includes a driving part fixed to the positioning rod (4) and a transmission part spanning between the driving part and the corresponding template (2). The templates (2) driven by the driving assembly close together and enclose to form a blow molding cavity.

2. A bottle blowing apparatus according to claim 1, wherein The frame (3) has two parallel and vertically separated positioning rods (4) between its corresponding end edges. The positioning rods (4) have a square cross section and an mounting surface.

3. A bottle blowing apparatus according to claim 2, wherein The frame (3) is fixedly connected to the frame (1) above and encloses to form an active space for the template (2) to open and close in a mirror image. The template (2) can slide back and forth in a mirror image along the length of the active space and switch between opening and closing.

4. A bottle blowing apparatus according to claim 3, wherein The inner wall bottom edge of the frame (3) is provided with a guide rail (5) laid along the length of the activity space. The bottom of the template (2) is fixed with a horizontally arranged slide plate (6). The bottom surface of the slide plate (6) is provided with a slider that can cooperate with the guide rail (5). The slider slides along the guide rail (5) and guides the template (2) to open and close in a mirror manner.

5. A bottle blowing apparatus according to claim 4, wherein The drive unit is fixed to the lower positioning rod (4), and the transmission unit is disposed between the drive unit and the slide plate (6). The drive unit drives the template (2) fixed to the slide plate (6) to slide along the guide rail (5) through the transmission unit.

6. A bottle blowing apparatus according to claim 4, wherein The driving unit is a motor (7) with a driving gear (8), and the transmission unit is a rack (9) set on the slide plate (6). The motor (7) meshes with the rack (9) through the driving gear (8) to make the slide plate (6) move back and forth and drive the template (2) to open and close. The slide plate (6) is provided with a clearance groove (10) to avoid the driving gear (8).

7. A bottle blowing apparatus according to claim 4, wherein The driving part is a cylinder (11), and the transmission part is a telescopic rod (12) that is telescopically mounted on the cylinder (11). The end of the telescopic rod (12) is fixedly connected to the slide plate (6) so that the slide plate (6) moves back and forth and drives the template (2) to open and close.

8. A bottle blowing apparatus according to any one of claims 1 to 7, wherein The frame (3) is provided with a limiting component, which includes a limiting member (13) that can move up and down between the positioning rod (4) and the corresponding template (2) and a driving member (14) fixed on the upper positioning rod (4). When the mold assembly is in the mold closing state, the limiting member (13) is vertically inserted between the positioning rod (4) and the corresponding template (2) under the drive of the driving member (14) to restrict the template (2) from separating in opposite directions.

9. A bottle blowing apparatus according to claim 8, wherein The driving component (14) is fixed to the bottom surface of the positioning rod (4). The telescopic end of the driving component (14) is fixed to the limiting component (13) through the connecting plate, so that the limiting component (13) can be raised and lowered between the limiting station clamped between the positioning rod (4) and the corresponding template (2) and the idle station that is misaligned with the positioning rod (4).

10. A bottle blowing apparatus according to claim 9, wherein When the mold assembly is in the mold-closed state, the distance between the template (2) and the positioning rod (4) is equal to the width of the limiting member (13), so that the template (2) and the positioning rod (4) clamp the limiting member (13) which has been switched to the limiting position and keep its relative position fixed; or, the template (2) is provided with a positioning plate (15) that is the same height as the positioning rod (4) and is horizontally arranged towards the positioning rod (4), and the limiting member (13) is switched to the limiting position and is locked between the positioning plate (15) and the positioning rod (4).
