detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. However, it should be noted that the description of the following embodiments is schematic and does not constitute a specific limitation to the utility model.

Referring to Fig. 1 and Fig. 2, a mold clamping mechanism of a bottle blowing machine includes a mold base 1 on which two locking plates 2 are arranged, and the two locking plates 2 are all slidably arranged on the mold base 1 Above, in this embodiment, two slide rails 3 are arranged symmetrically on the formwork 1, and the locking plate 2 is installed on the slide rails 3, and a lever arm 4 is respectively hinged on the left and right sides of the formwork 1, and the two levers One end of the arm 4 is respectively connected with the lock plate 2, and the other end is jointly connected with a lifting block 5 that can drive it to rotate to push the lock plate 2 to move laterally. Lifting block 5 reciprocating up and down feed structure 6.

In this embodiment, the locking plate 2 is hinged with a first connecting rod 7, and the other end of the first connecting rod 7 is hinged with the upper part of the lever arm 4; the lifting block 5 is hinged with a second Two connecting rods 8 , the other end of the second connecting rod 8 is hinged to the lower part of the lever arm 4 . The lever arm 4 can also be connected with the locking template 2 and the lifting block 5 through the following structure. The upper and lower parts of the lever arm 4 are respectively provided with a waist-shaped hole. The first rolling wheel in the waist-shaped hole of the lifting block 5 is hinged with a second rolling wheel that can be slidably arranged in the waist-shaped hole on the top of the lever arm 4 .

The lifting and feeding structure 6 includes a servo motor 61 arranged on the mold base 1, the servo motor 61 is connected with a lead screw 62, and the lifting block 5 is provided with a screw thread matching the lead screw 62. hole.

The servo motor 61 is connected with the lead screw 62 through a reducer 63, the reducer 63 is preferably a planetary reducer, and the torque generated by the servo motor 61 through the rotation of the lead screw 62 driven by the planetary reducer is much greater than that produced by the servo The motor 61 directly drives the torque generated by the lead screw 62, which is conducive to driving the stability of the lifting movement of the lifting block 5. Lifting and feeding mechanism 6 can also be the following structure except the above structure: the servo motor drives the gear to rotate, and then the gear drives the rack to move up and down, and the rack is fixedly connected to the lifting block 5 .
