Technical Field

[0001] The utility model belongs to the technical field of gas-assisted injection molding, and particularly relates to an integrated gas-assisted pressure boosting and control machine. Background Art

[0002] Gas-assisted injection molding is an advanced plastic molding technology. By injecting high-pressure gas (usually nitrogen) during the cooling process of plastic parts, it can reduce the material usage, reduce the weight, and improve the structural strength of the parts, and is applicable to complex parts with internal cavities or thin-wall structures.

[0003] Traditional gas-assisted injection molding technology has limitations in movement: traditional gas-assisted injection molding systems face the problem of unstable gas supply, resulting in inconsistent molding quality. Early systems may lack precise pressure and flow control and are difficult to meet the requirements of high-end applications. Traditional systems are often composed of multiple independent components, occupying a large space and being inconvenient for installation and maintenance, etc.

[0004] Therefore, the utility model proposes an integrated gas-assisted pressure boosting and control machine that integrates functions such as gas boosting, control, and transportation to solve the above problems. Content of the Utility Model

[0009] The utility model is further arranged such that signal terminals and a power socket are arranged on the back of the electric control box, and a cover plate is detachably assembled on the top of the electric control box.

[0009]

[0010] The utility model is further configured such that a pressure gauge is embedded in the upper part of the front surface of the casing, and the detection end of the pressure gauge is connected to a pipeline system built in the casing.

[0011] The utility model is further configured such that an air delivery end is embedded at the bottom of one side of the casing, and an air intake end is embedded in the other side of the casing. The air intake end is matched with the air intake port of the proportional valve. A filter is adaptively installed on the air delivery end, and the filter is connected to a high-pressure output pipe.
