Linkage mechanism of side moulds and bottom mould of bottle blowing machine

Abstract

The invention discloses a linkage mechanism of side moulds and a bottom mould of a bottle blowing machine. The side moulds and the bottom mould of the bottle blowing machine are connected by a linkage connecting rod device; the linkage of the side moulds and the bottom mould is realized by opening-closing motion of the side moulds and lifting motion of the bottom mould; the bottom mould descends when the side moulds are opened; the bottom mould ascends when the side moulds are closed until the set position is totally closed. The linkage of the side moulds and the bottom mould is realized by opening-closing motion of the side moulds and lifting motion of the bottom mould, and the linkage mechanism has a simple structure, is easy to manufacture and maintain, and reduces the manufacturing cost and the maintenance cost; each component is matched in a hinging or rolling mode and is free of mechanical shock during motion, so that the fault rate of each component is greatly reduced, the stability of the equipment is increased, the operation speed can be safely increased, the production efficiency is improved, and the noise is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of plastic bottle blow molding machines, in particular to a linkage mechanism of a side mold and a bottom mold of a blow molding machine. Background technique [0002] Blow molding machine is equipment in the field of processing and manufacturing plastic bottles such as beverage bottles, oil bottles, and medicine bottles. The blow molding machine includes a left mold, a right mold and a bottom mold. The three cooperate to form a complete bottle cavity. , right mold and bottom mold and place the preform in the cavity, then close the left and right molds and bottom mold to blow the preform, and open the left and right molds and bottom mold after the bottle is formed At this time, the bottom mold descends and exits the cavity position, and the bottle body after processing is taken away and sent to the next process. [0003] Such as figure 1 , 2 As shown, it is a structural schematic diagram of a bottle blow...

AI Technical Summary

Problems solved by technology

It has the following problems: 1. The opening and closing movement of the left and right mold bases, and the lifting movement of the bottom mold 105 are controlled by the opening and closing mold guide rail 111 and the bottom mold guide rail 112 respectively, which makes the equipment bulky, takes up space, and has a complicated structure , Difficult to maintain, high cost investment; 2. The precision of motion coordination between the left and right molds and the bottom mold 105 is high, which requires a large maintenance cost; 3. When the equipment is running, the rollers enter the guide rail to drive other parts to move until they break away from the guide rail. During this process, the rollers and the guide rails are pressed against each other and move relative to each other, which generates a lot of noise. At the same time, when the rollers enter the guide rails, due to a certain gap in the fit, the rollers hit the guide rails, resulting in noise. Therefore, many The cooperation between the rollers and the guide rails will generate a lot of noise, which will affect the operation, health and safety of the operators; 4. The rollers require high structural precision, and they will frequently collide with the guide rails during the movement, resulting in damage to the rollers. Affect the work efficiency of the equipment and increase the cost input
