Description
Technical Field
The invention relates to the technical field of bottle blowing machines, in particular to a combined connecting rod mechanism for linkage of an opening and closing die and a bottom die of a bottle blowing machine.
Background
The bottle blowing machine is a key device for producing various plastic bottles for liquid packaging. The bottle blowing machine has strict requirements on all procedures, has high requirements on mutual matching, and particularly has strict requirements on synchronous control of opening and closing movement of an opening die and a bottom die lifting movement.
The existing mechanisms for realizing synchronous motion of the bottom die and the opening and closing die mainly comprise two types: one is a cylindrical space cam mechanism; the other type is a composite mechanism formed by a space four-bar linkage mechanism and a plane cam mechanism.
The first mechanism has the advantages that: the mechanism is simple, and the moving parts are few. The first type of mechanism has the disadvantages that: 1) the cam flange or groove profile of the cylindrical space cam has high requirements on the design and processing precision, the installation and positioning difficulty of the cam is high, and a rotor is easy to clamp; 2) the rotor and the cam profile contact surface are easy to form point contact, the pressure stress is large, and the rotor is easy to damage or the cam profile surface is easy to wear; 3) due to space size limitations, cam pressure angles are typically large, and as such, rotors are prone to damage or cam profile wear.
The second mechanism has the advantages that: the design, processing and installation of the spatial four-bar linkage mechanism and the planar cam mechanism are simpler than those of the first type of mechanism. The second type of mechanism has the disadvantages that: the pressure angle of the cam is large, so that the rotor is easy to damage or the profile surface of the cam is easy to wear, the dynamic load transmitted to the connecting rod in the space four-bar mechanism is large, and the connecting rod is easy to destabilize when being pressed, thereby directly influencing the high-speed performance of the whole bottle blowing machine.

When the opening and closing mold rotor arm 10 swings (i.e., swings around the axial lead direction of the opening and closing mold swing shaft 11), the opening and closing mold rotor arm is used for driving the left mold frame 1 and the right mold frame 2 to make opening and closing movements.
The bottom die swing arm 12 is fixedly connected to the opening and closing die swing shaft 11 or the left die frame 1 or the right die frame 2, two ends of the space connecting rod 13 are respectively hinged to the bottom die swing arm 12 and the bottom die 6 through spherical surfaces of joint bearings, and two ends of the space connecting rod 13 are respectively fixedly connected with the two joint bearings. The bottom die support 9 is fixedly arranged on the die carrier support 8, and the bottom die 6 can do lifting motion on a bottom die guide rail 7 fixedly connected on the bottom die support 9. When the opening and closing mold rotor arm 10 swings (i.e., swings around the axial lead of the opening and closing mold swing shaft 11), it is used to drive the bottom mold 6 to move up and down.
