Abstract

The invention belongs to feeding equipment and in particular relates to a piston type high-pressure feeding machine. The machine comprises a cylinder, a piston type push rod in airtight fit with the inner wall of the machine and capable of linearly moving and an opening arranged on the front part of the cylinder. An end cover in fastened fit with the inner side wall of the cylinder is fixed on the front end of the cylinder. The opening is arranged on the end cover and communicated with the inner cavity of a mould. A power source is connected to the rear part of the piston type push rod. According to the piston type high-pressure feeding machine disclosed by the invention, the problems of incapability of rapid material feeding and manufacture influence of a polyurethane work-piece in the prior art can be solved; and the machine has the advantages of rational structural design, wide application range, convenient use and the like.

Description

technical field [0001] The invention belongs to injection equipment, in particular to a piston-type high-pressure injection machine. Background technique [0002] At present, in the production process of castable polyurethane pipe fittings (small-caliber thin-walled pipe fittings), since the solidification time of the material is short after liquefaction and vulcanizing agent is added, and it becomes more viscous after adding other auxiliary materials, it cannot be completed by manual pouring, which affects the pouring type. For the molding and manufacture of polyurethane workpieces, the existing commercially available polyurethane pouring machines cannot be used for pouring viscous raw materials. Contents of the invention [0003] The purpose of the present invention is to provide a piston-type high-pressure injection machine with simple structure to effectively solve the problem that viscous materials cannot be quickly injected into the mold from bottom to top. [0004]...
