Problems solved by technology

[0002] The sealing tube assembly is generally used for partial sealing in the field of low-pressure casting. Most of the existing sealing tubes are circular tubes with a tapered bottom, which can be installed and sealed with the corresponding base. The whole has the convenience of quick disassembly, but in In actual use, since the sealing tube is mostly fixed at the head end, the whole is prone to tilting and the sealing failure

Abstract

The invention discloses a stable and high-airtightness sealing pipe assembly. The assembly mainly comprises a base and a sealing pipe; a conical head is integrally molded at the bottom of the sealingpipe; a circular step sinking inwards is arranged on the bottom edge of the base; a big-end-up conical hole is formed in the upper surface of the base; and a communicating cavity is butt-jointed at the lower end opening of the conical hole. Any part of the sealing pipe can be fixedly sleeved with a stabilizing sleeve of the assembly, and meanwhile, the stabilizing sleeve cannot deviate horizontally under the effect of guide columns, so that the sealing pipe can be prevented from being tilted, and the overall sealing effect is more outstanding.

Description

technical field [0001] The invention relates to the field of casting, in particular to a stable and highly airtight sealing pipe assembly. Background technique [0002] The sealing tube assembly is generally used for partial sealing in the field of low-pressure casting. Most of the existing sealing tubes are circular tubes with a tapered bottom, which can be installed and sealed with the corresponding base. The whole has the convenience of quick disassembly, but in In actual use, since the sealing tube is mostly fixed at the head end, the whole is prone to tilting and sealing failure. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned situation, the present invention aims to provide a technical solution capable of solving the above-mentioned problems. [0004] A stable and highly airtight sealing tube assembly mainly includes a base and a sealing tube. The bottom of the sealing tube is integrally formed with a tapered head; T...
