Problems solved by technology

Although the one-line injection molding machine disclosed in this invention patent has the advantages of simple structure, small mass of moving parts, good controllability, and non-rotating piston, it is suitable for high-speed, high-precision injection molding product production. However, the cylinder of this one-line injection molding machine The body adopts an integral structure, so it will be very troublesome in the assembly process; on the other hand, because the cylinder body of this integral structure is not convenient for positioning the hollow piston rod, that is, this one-line injection molding machine will Among them, there is a shortcoming that the concentricity between the hollow piston rod and the transmission shaft is not high
In summary, the cylinder structure of this one-line injection molding machine has the disadvantages of troublesome assembly, poor work performance and poor practicability.

Embodiment 1

[0017] Such as figure 1 with figure 2 As shown, an injection molding machine cylinder structure includes a cylinder block 1 and a hollow piston rod 2 arranged inside the cylinder block 1. The cylinder block 1 is movably connected to the hollow piston rod 2, and the cylinder block 1 includes a front cylinder block 11. The rear cylinder block 12 and the end cover 13, the front cylinder block 11 and the rear cylinder block 12 are fixedly connected together by interference fit, and the end cover 13 is fixed to the end of the rear cylinder block 12 by screws, By designing the cylinder block 1 into three parts, the front cylinder block 11, the rear cylinder block 12 and the end cover 13, it is very convenient to assemble the hollow piston rod 2 inside the cylinder block 1 during the assembly process of the present invention. That is to achieve the purpose of simplifying the assembly operation of the present invention.

Embodiment 2

[0022] In this embodiment, the structure and connection relationship of the cylinder block 1, the hollow piston rod 2, the positioning steel washer 3, the sealing ring 4, the oil passage 6, the oil cup 7, the oil discharge port 8, and the feeding mechanism 9 are the same as those of the above embodiment 1. The same in.

[0023] The difference is that in this embodiment, an oil baffle ring 5 is fixedly connected to the side of the positioning steel washer 3, and the oil baffle ring 5 is sleeved and movably connected with the hollow piston rod 2. By adding the oil baffle ring 5 to meet the beneficial effects of the present invention, it can further increase the service life of the positioning steel washer 3, and at the same time ensure the hollow piston rod 2 to work more stably and efficiently, that is, to enhance the present invention Practical purpose.

Abstract

The invention discloses an injection molding machine cylinder structure which comprises a cylinder and a hollow piston rod arranged in the cylinder. The cylinder and the hollow piston rod are movably connected. The cylinder comprises a front cylinder body, a rear cylinder body and an end cover. The front cylinder body and the rear cylinder body are fixedly connected in an interference fit mode, the end cover is fixed to the end of the rear cylinder body through a screw, and a steel positioning washer is fixed in the front cylinder body and movably connected with the hollow piston rod in a sleeving mode; and a sealing ring is arranged between the steel positioning washer and the hollow piston rod and fixed to the steel positioning washer. The injection molding machine cylinder structure has the characteristics of being convenient to assemble, good in working performance and high in practicability.

Description

Technical field [0001] The invention belongs to the field of machinery, and relates to an injection molding machine structure, in particular to an injection molding machine cylinder structure. Background technique [0002] Injection molding machines are widely used in the processing and molding processes of plastic products. There are many types of injection molding machines commonly used in the market. The most commonly used one is the one-line injection molding machine, which includes a cylinder and a hollow piston located inside the cylinder. Rod. For example, the Chinese invention patent No. 201310348001.0 discloses a one-line piston non-rotating injection cylinder structure of an injection molding machine, which includes a hydraulic oil motor, an injection cylinder, a transmission sleeve connected to the hydraulic oil motor, and one end connected to the transmission sleeve The transmission shaft, the screw fixedly connected to the other end of the transmission shaft, and a ...
