Abstract

The invention discloses a hydraulic ejection structure of a plastic mold. The hydraulic ejection structure comprises an oil hydraulic cylinder arranged on a mold foot of the plastic mold, an oil way arranged in the mold foot and communicated with the oil hydraulic cylinder, and a connecting rod; and one end of the connecting rod and a stretchable end of the oil hydraulic cylinder are fixed, and the other end of the connecting rod and an ejection plate of the plastic mold are fixed. Compared with the prior art, the hydraulic ejection structure of the plastic mold has the beneficial effects thatthe oil way is arranged in the mold foot of the plastic mold, and therefore an oil pipe is prevented from being damaged by pressing in the mold installing, mold detaching and transporting process; the oil pipe is arranged in the mold foot, the space is reduced, and interference with other structures of the outer side of the mold can be avoided; the service life is longer than that of the oil pipe; and after the oil hydraulic cylinder is installed, oil hydraulic cylinder detachment is not needed in the follow-up maintenance and mold detaching, and the problem of oil leakage does not exist.

Description

【Technical field】 [0001] The invention relates to a hydraulic ejection structure, in particular to a hydraulic ejection structure of a plastic mold. 【Background technique】 [0002] The plastic injection of the male mold is a commonly used mold structure in the design of plastic molds, and the injection molding of the male mold is basically ejected by hydraulic pressure (hydraulic cylinder). [0003] Please refer to figure 1 , figure 1 It is shown as a cross-sectional view of a hydraulic ejection structure of a plastic mold in the prior art, figure 2 It is a cross-sectional view of a hydraulic ejection structure of a plastic mold in the prior art at a second viewing angle. [0004] As shown in the figure, the hydraulic ejection structure includes a hydraulic cylinder 101 , an oil collecting block 102 , an oil pipe joint 103 and an oil pipe 104 . This structure has the following disadvantages: 1. Since the oil pipe 104 is arranged on the outside of the plastic mold, it is...
