The invention relates to a single-cylinder injection device, which comprises an injection seat, wherein the front end of the injection seat is connected with a machine barrel; a screw rod is arranged in the machine barrel; an end cover is arranged at the rear end of the injection seat; a transmission sleeve is arranged in the end cover; a hydraulic motor is arranged outside the end cover; an output shaft of the hydraulic motor is arranged in the transmission sleeve; a transmission shaft is also arranged in the transmission sleeve and is connected with the screw rod; a piston is sleeved outside the transmission shaft; a transparent cover and a cylinder body are sleeved outside the piston in a sealing way; the cylinder body is connected with the end cover in a sealing way; the transmission sleeve, the transmission shaft, the piston, the transparent cover and the cylinder body are positioned inside the injection seat; a front oil cavity is formed between the transparent cover and the piston; a front oil hole which is communicated with the front oil cavity is formed in the transparent cover and passes through the injection seat to be communicated with the outside; a rear oil cavity isenclosed by the piston, the cylinder body and the end cover; and a rear oil hole which is communicated with the rear oil cavity is formed in the end cover. The single-cylinder injection device is suitable for an injection molding machine, has low energy consumption, a simple structure, light weight and a small number of parts and is convenient to manufacture.
Description
technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a single-cylinder injection device. Background technique [0002] Existing injection molding machines of various specifications, most of which adopt the oil cylinder structure, are mostly double-cylinder injection devices equal to the injection screw, which have high energy consumption, large volume, heavy weight, many parts, and difficult manufacturing, and the double-cylinder injection device The synchronization is poor, and it is easy to cause a series of disadvantages such as uneven force. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a single-cylinder injection device with low energy consumption, simple structure, light weight, few parts and convenient manufacture. [0004] In order to solve the above problems, the technical solution adopted in the present invention is: a single-cylinder inj...
