Abstract

The invention relates to a casting oil cylinder. The casting oil cylinder comprises a cylinder body, a cylinder head connected with the cylinder body, a plunger piston stretching into the cylinder body, a piston located at the end portion of the plunger piston, a guiding key installed to the inner wall of the cylinder body, an upper end cover installed to the cylinder head, a lower end cover installed to the cylinder body and an oil mouth located in the cylinder head, wherein the position, in contact with the guiding key, of the piston is provided with a guiding slot, the shape and size of theguiding slot are matched with the shape and size of the guiding key, and the guiding key is embedded inside the guiding slot, the length of the cylinder head is 20% of that of the cylinder body, andthe diameter of the plunger piston is less than or equal to the difference between the inner diameter of the cylinder body and the height of the guiding key. According to the casting oil cylinder provided by the invention, by means of the arrangements of the guiding key and the guiding slot, the effect of whole-course accurate guiding is realized, rotating of the oil cylinder is prevented, and theproduct quality of aluminum bars produced adopting the casting oil cylinder is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aluminum profile casting equipment, in particular to a casting oil cylinder. Background technique [0002] The casting cylinder is a device that guides and provides the power required for casting when aluminum alloy is casting aluminum rods. As an important part of the casting machine, its quality directly affects the ingot products produced by the casting machine quality. Due to the fact that aluminum ingots often break during the casting process, when this phenomenon occurs, the pressure on the casting cylinder will be unequal, resulting in the rotation of the piston rod inside the casting cylinder, which cannot achieve accurate guidance and cannot provide stable The power affects the product quality of the ingot. Therefore be necessary to propose a kind of novel casting oil cylinder, solve the above problems. [0003] The invention provides a casting oil cylinder, which realizes the positioning of t...
