Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] refer to figure 1 , is a stable self-locking structure for an oil hydraulic cylinder disclosed in the present invention, including a driving assembly 1 and a driven assembly 2 detachably connected to the oil output shaft, and the driving assembly 1 includes a connecting shaft detachably connected to the oil cylinder output shaft 3 Section 11, driving straight plate 12, driving inclined plate 13 and extending end plate 14.

[0030] to combine figure 1 and figure 2 As shown, the length direction of the driving straight plate 12 forms an acute angle with the length direction of the driving swash plate 13, and the extended end plate 14 is parallel to the length direction of the driving straight plate 12; The inclined force hole 22 on the top, the driving inclined plate 13 is slid and inserted in the inclined force hole 22. A stable self-locking space ...

Abstract

The invention relates to a stable self-locking structure for an oil hydraulic cylinder, which includes an active assembly and a driven assembly that are detachably connected to the output shaft of the oil cylinder. The length direction of the driving swash plate forms an acute angle with the length direction of the driving swash plate. The driven assembly includes a driven block and a force-bearing inclined hole penetrating through the driven block. The driving swash plate slides and is inserted in the force-receiving inclined hole. A stable self-locking space is formed between the side wall of the plate close to the side wall of the inclined hole under force and the side wall of the inclined hole under force. When moving, the driving swash plate moves synchronously, and the driven block can be driven to move after the driving swash plate and the side wall of the inclined hole are pressed. When the stable self-locking space exists, even if the output shaft of the oil cylinder vibrates, it will not move in the stable self-locking space. And under the action of the extended end plate, the stable movement of the driven block can be maintained.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a stable self-locking structure for an oil hydraulic cylinder. Background technique [0002] At present, the manufacturing of molds is mostly carried out by injection molding, generally driven by hydraulic cylinders, and the transmission device is used to press the molten liquid into the molding cavity of the mold. [0003] However, due to its own reasons, the existing oil pressure cylinder may cause the output shaft of the oil pressure cylinder to vibrate due to its oil pressure stability, which will affect the manufacturing quality of the mould, which needs to be solved. Contents of the invention [0004] In view of the deficiencies in the prior art, one of the purposes of the present invention is to provide a stable self-locking structure for hydraulic cylinders that improves transmission stability. [0005] Above-mentioned purpose of the invention of the present...
