Bottom die and die set link mechanism of bottle blowing machine

Abstract

The invention discloses a bottom die and die set link mechanism of a bottle blowing machine, which ensures that the opening and the closing of a die set and the ascending and the descending of a bottom die are integrated, namely the bottom die descends or ascends when the die set is opened or closed. The link mechanism has the effects of improving the matching precision between the bottom die and the die set in the working process, also simplifying equipment, saving the used space, reducing the cost, effectively reducing the noise intensity, prolonging the service life of a roller and avoiding huge impact caused by the fact that the roller is in instant contact with a corner of a lifting guide rail of the bottom die when the equipment rotates at a high speed.

Description

technical field [0001] The invention relates to a connecting rod mechanism, in particular to a linkage connecting rod mechanism between a bottom mold and a mold base of a bottle blowing 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 left and right mold frames that can be opened and closed. The opening and closing device of the frame makes the opening and closing movement. After the left and right mold frames are closed, a cavity is formed inside, and there is another bottom mold that extends into or exits the cavity through the lifting device. The entire blowing process of the blow molding machine is compact and saves It saves time and effort, and the blow molding machine can automatically cycle, which improves the work efficiency. [0003] Such as figure 1 , figure 2 and image 3 As shown,...

AI Technical Summary

Problems solved by technology

The problems existing in the prior art are as follows: 1. With the gradual increase of the operating speed of the equipment, the precision of cooperation between the lifting of the bottom mold, the opening and closing of the mold base and the lifting of the clamping pin is relatively high, so that the lifting guide rail of the bottom mold 1. The higher the accuracy requirements of the mold base opening and closing guide rails and the mold locking guide rails; 2. With the gradual increase of the operating speed of the equipment, when the rollers run to the corners of the bottom mold lifting guide rail surface, the impact sound caused by the instantaneous contact with the corners becomes more and more large, and the noise will become more and more loud when the roller runs on the guide rail, which will affect the working environment; 3. Because the roller touches the corner momentarily and produces an impact, the impact force is large, and the roller is hard and brittle. Therefore, when the roller is running at high speed, it is easy to be damaged damaged by impact

4. The opening and closing movement of the left and right mold bases, the lifting of the locking pin and the lifting of the bottom mold are controlled by the opening and closing guide rails, the locking mold guide rails and the bottom mold lifting guide rails respectively, so that the equipment is bulky, takes up space, and has a complex structure and difficult maintenance , high cost input
