Problems solved by technology

[0002] Existing molds for slender tubular products, such as test tube molds, the positioning of the slender core of the rear mold is unreliable, and elastic deformation occurs under strong injection pressure, resulting in eccentricity of the product, so the produced product often occurs eccentricity This leads to uneven wall thickness, which makes the product fail to meet the technical requirements

Abstract

The invention provides a mould structure of a slender tubular product, which is used for ensuring the reliability in locating a slender mould core of a back mould, preventing a manufactured product from being eccentric, ensuring that the wall thickness of the product is even, and further enabling the product to meet the technical requirements. The mould structure of the slender tubular product comprises a front mould, a back mould, a tube body excircle mould core, a slender mould core and a fixed shaft sleeve, wherein a cavity among the front mould, the back mould, the tube body excircle mould core and the slender mould core is a diccavity; the fixed shaft sleeve is sleeved on the excircle surface at the middle-lower part of the slender mould core; and the bottom of the slender mould core is tightly fixed on a fixed plate. The mould structure of the slender tubular product is characterized in that a gap between the fixed shaft sleeve and the slender mould core is internally provided with a steel ball liner in a filling manner, the steel ball liner is sleeved on the excircle surface of the slender mould core, and the outer surface of the steel ball liner is attached to the inner circle surface of the fixed shaft sleeve.

Description

technical field [0001] The invention relates to the technical field of injection mold structures, in particular to the mold structure of elongated tubular products. Background technique [0002] Existing molds for slender tubular products, such as test tube molds, the positioning of the slender core of the rear mold is unreliable, and elastic deformation occurs under strong injection pressure, resulting in eccentricity of the product, so the produced product often occurs eccentricity This leads to uneven wall thickness, which makes the product fail to meet the technical requirements. Contents of the invention [0003] The invention provides a mold structure for a slender tubular product, which ensures reliable positioning of the slender core of the rear mold, prevents eccentricity of the manufactured product, ensures uniform wall thickness of the product, and further enables the product to meet technical requirements. [0004] The mold structure of a slender tubular produ...
