Fourthly, according to the characteristics of automobile complex plastic parts, the drive form of the injection molding machine and the design of the mold clamping mechanism are currently used hydraulically mechanically or fully hydraulically. Institutional injection molding machine. After many years of efforts, Terry Machinery Co., Ltd. broke through the traditional constraints and developed a mechanical structure with two-plate clamping and direct compression and composite clamping.
The advantage of this structure is that its open stroke is far greater than the hydraulic toggle clamp structure, at least more than 2 times, to meet the production needs of large automotive plastic parts (such as bumpers, dashboards, etc.). Secondly, the mode locking uses four composite oil cylinders to lock synchronously, and the large-tonnage smooth clamping is realized with a small flow rate. The clamping force can be higher than the hydraulic toggle clamp structure with the same tonnage. Accurately guarantee the precision of molding composite surfaces of large-scale complex plastic parts of automobiles.
Fifth, because the cavity surface of auto parts is very complex, the injection molding machine must consider its particularity when designing, and configure some special function programs: such as multi-group core pulling function, timing control function, injection molding machine matching mold changing device function , matching pick-up robot device features. These special features have obvious advantages in producing automotive plastic parts. For example, in order to shorten the production cycle, this type of injection molding machine is used to automatically remove the large-scale plastic product parts after the mold is ejected by the pick-up robot, and the multi-group pull cores make the large-scale plastic products steadily integrated. Out, no whitening or cracking. At present, most of the robots used in this injection molding system are 3-axis pick-up robots and 6-axis pick-up robots.
