Description

Technical Field

[0001] This utility model relates to the field of mechanical tool technology, specifically to a pipe positioning and shearing mechanism. Background Technology

[0002] When injection molding tubular components, multiple plastic parts are typically molded together, resulting in finished products consisting of multiple connected tubular components that require subsequent shearing. Traditional methods for removing the edges of injection-molded tubular components mostly involve operators using hand-held pliers to cut the connected portions of the components. This requires multiple cuts to complete a single tubular component, which is time-consuming, labor-intensive, and unsafe. Furthermore, existing tubular component shearing devices struggle to effectively position the components, leading to misalignment during shearing and low efficiency.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a simple injection molding pipe shearing device [CN202011537148.0], which includes a bracket, a shearing mechanism, a clamping mechanism, a pushing mechanism, a slide rail, and a material box. The shearing mechanism is fixedly installed on the upper right side of the front part of the bracket. The clamping mechanism is slidably connected to the lower right side of the upper front plate of the bracket. The pushing mechanism is connected to the middle right side of the front part of the bracket, with part of the pushing mechanism located below the clamping mechanism. The slide rail is fixedly installed on the lower side of the groove in the middle position of the bracket.

[0004] The above solution addresses, to some extent, the problems of time-consuming, labor-intensive, and unsafe manual cutting of pipe fittings in existing technologies. However, it still has many shortcomings, such as difficulty in effectively positioning the pipe fittings, easy misalignment during cutting, and low cutting efficiency. Summary of the Invention
