Description

Technical Field

[0001] The utility model relates to the field of molding machines, in particular to a pressurized air supply pipeline for a sand shooting box. Background Art

[0002] The compressed air machine can provide sufficient pressure and flow for the sand shooting box of the molding machine through the pressurized air supply pipeline. The pipeline design and layout need to consider the stability and uniformity of the air flow to ensure that the sand can enter the mold or sand mold evenly. The pneumatic control system includes equipment such as pressure regulation, flow control and pneumatic valves to control the size of the air supply pressure and flow. In addition, it is necessary to understand the knowledge of pneumatic principles, selection and use of pneumatic components, etc. in order to effectively apply the pressurized air supply pipeline technology for sand shooting operations.

[0003] In the existing molding machines for making sand molds, the molding machine sand shooting box uses a pressurized air supply pipeline to provide compressed air during the sand shooting process. The pressurized air supply pipeline can provide sufficient pressure to enable the sand to enter the mold or sand mold quickly and evenly, thereby improving the sand shooting efficiency. By adjusting the air supply pressure and flow rate, the fluidity of the sand can be accurately controlled to adapt it to different mold shapes and size requirements. The pressurized air supply pipeline can ensure that the sand completely fills the mold or sand mold, reducing the waste of sand and subsequent processing work.

[0004] However, the existing pressurized air supply pipeline requires special equipment and pipeline system, which increases the complexity and maintenance cost of the equipment. The pressurized air supply pipeline has certain requirements on the fluidity and particle size of the sand material. Therefore, there is an urgent need for a pressurized air supply mechanism for a sand shooting box that is easy to operate. Utility Model Content
