Embodiment Construction

[0009] like figure 1 As shown, a quick-adjusting oil cylinder includes an oil cylinder barrel 2, a piston 1 is installed in the oil cylinder barrel 2, a piston rod 4 is connected below the piston 1, and the piston rod 4 is divided into an upper section and a lower section, and the upper section and the piston The rods 4 are matched and connected, and the lower section is equipped with a gland 3, and a second plastic injection plate 5 is arranged below the gland 3, and the number of the oil cylinders 2 is two, which are left and right symmetrical, and are connected by a fixed plate 6. The gland 3. A buffer pad is installed on the bottom. The structure of the invention is simple. When the piston is running, the gland hits the second rubber injection plate. At this time, the piston does not need to retreat to the bottom to avoid the accumulation of processing errors, so that the piston rod will not break, which greatly improves the use of the cylinder. Second, the gland behind th...

Abstract

The invention relates to a quick adjustment oil cylinder. The oil cylinder comprises oil cylinder barrels, wherein a piston is mounted in each oil cylinder barrel; a piston rod is connected to the bottom of the piston, and is divided into an upper section and a lower section; the upper section is in fitting connection with the piston rod, and the lower section is provided with a gland; and a glue ejecting second plate is arranged below the glands. The oil cylinder is simple in structure; when the pistons are operated, the glands collide with the glue ejecting second plate, and the pistons have no need to thoroughly retreat to prevent the processing accumulation error, so that the piston rods are not broken, and the service life of the oil cylinder is largely prolonged; and glands behind the piston rods are omitted, so that the assembly is simpler and more convenient.

Description

technical field [0001] The invention relates to an oil cylinder of an injection molding machine, in particular to a quick-adjusting oil cylinder. Background technique [0002] When the injection molding machine opens and closes the mold, it needs the oil cylinder to drive the movable platen, and the movable platen drives the mold to open and close the mold. At present, the double-cylinder injection is widely used in domestic plastic machines, and it takes a long time to use. After being used by customers, the piston rod breaks a lot. , mainly due to the processing error of the parts and the difficulty of assembly adjustment. For example, the application number is 201110030246.X, and the application date is 2011.01.27 "Injection Molding Machine Oil Cylinder Piston Limiting Mechanism". The piston assembly is installed in the oil cylinder barrel, and the oil cylinder barrel, the oil cylinder head and the piston assembly form the oil cylinder, which is characterized in that a su...
