Abstract

The present patent discloses a hydraulic machine for grease, which make a plurality of short hydraulic cylinders for grease that provide the mould-locking force of mould-clamping mechanism connected to a single pump for lubricant grease respectively, thus supplying grease to each short hydraulic cylinder independently and avoiding many problems such as long pipe line, large loss in pipe, slow speed and long time of route due to the central supplying grease mode in which all short hydraulic cylinders for grease share a common pump for grease. Moreover, the pump for lubricant grease is provided with a grease storage, and could be mounted close to the short hydraulic cylinders for grease and formed closed loops together with the short hydraulic cylinders for grease. All loops are independent and separated from each other without influencing each other, while they use a common power source and operate synchronously. In this way, it brings into a merit of without oil leaking and pollution in the transmission of grease pressure, long period in maintaining pressure, and it meets the requirement for reducing operation time. If the opening and closing mould unit uses mechanical drive or hydraulic drive, expensive hydraulic pumping station can be eliminated, thus cost is evidently reduced.

本发明的脂压机，使锁模机构的提供锁模力的短脂压缸与向其提供润滑脂的润滑脂泵一一对应，润滑脂泵带有贮脂筒，润滑脂泵就近安装在短脂压缸旁并与短脂压缸组成闭式回路，各回路各自独立、互相分离、互不影响但共用动力源、同步运行。这样既充分发挥了脂压传动无油液泄漏和污染，保压时间长的优点，又满足了缩短操作时间的要求。若开合模机构采用机械传动或水压传动，则可省去价格昂贵的液压泵站，显著降低成本。本发明的脂压机管线短、管损小、速度快、行程时间短，不但可用作轮胎硫化机、轮胎硫化机组、橡胶注射成型机、注压成型机、橡胶平板硫化机、塑料注射成型机、塑料模压机、金属亚铸机等，还同样适用于存在类似应用的其他各领域。 The grease press of the present invention has a one-to-one correspondence between a short-pressure cylinder that provides a clamping force of a clamping mechanism and a grease pump that supplies grease thereto, the grease pump has a grease cartridge, and the grease pump is installed near Next to the short grease cylinder And with a short grease cylinder to form a closed circuit, each circuit is independent, separate from each other, but does not affect each other but share the power source and operate synchronously. In this way, the grease pressure transmission has no oil leakage and pollution, and the pressure holding time is long, and the operation time is shortened. If the opening and closing mechanism adopts mechanical transmission or hydraulic transmission, the expensive hydraulic pumping station can be omitted, and the cost is significantly reduced. The grease press of the invention has short pipeline, small tube loss, high speed and short travel time, and can be used not only as a tire vulcanizing machine, a tire vulcanizing unit, a rubber injection molding machine, a injection molding machine, a rubber flat vulcanizing machine, a plastic injection molding. Machines, plastic molding machines, metal sub-casting machines, etc., are equally applicable to other fields where similar applications exist.
