Abstract

The utility model provides a supporting frock of medical expansion mouth of pipe mould plug, including bush and plug, be equipped with air outlet channel on the plug, the most advanced outer wall of plug is equipped with the plug and adds the muscle position, and the plug adds muscle position and closely laminates with the bush inner wall, and the plug adds and forms the feeding clearance between the muscle position, and the material passes through the plug and adds the guiding effect back welt mould inner wall flow to discharge gate at muscle position. The utility model has the advantages that: compared with the traditional extruded pipe, the fixed relative position of the neck ring mold and the core rod is ensured by using the matched tool of the neck ring mold core rod, the concentricity is higher when the neck ring mold and the core rod are designed, the concentricity of the extruded expanding pipe can be ensured (other factors are eliminated), the manual operation process is simplified, and the time and the labor are saved.

Description

Matched tool for medical expanded pipe orifice mold core rod

Technical Field

The utility model relates to the field of medical equipment, more specifically say and relate to a supporting frock of medical expansion mouth of pipe plug.

Background

The expansion pipe is a medical instrument commonly used in interventional operations, when a material is extruded at present, the relative position of the neck ring and the core rod is not fixed, the concentricity between the neck ring and the core rod cannot be guaranteed, the concentricity of the expansion pipe after extrusion cannot be guaranteed, the relative position of the neck ring and the core rod needs to be determined according to the concentricity of the expansion pipe after extrusion of the material, if the expansion pipe with higher concentricity is needed, the relative position of the neck ring and the core rod needs to be adjusted manually, and time and labor are wasted.

Disclosure of Invention

The utility model overcomes the defects in the prior art and provides a matched tool for a medical expanded pipe orifice mold core rod.

The purpose of the utility model is realized by the following technical scheme.

The matched tool for the die core rod of the medical expanded pipe orifice comprises a die and a core rod, wherein an air outlet channel is arranged on the core rod, a core rod reinforcement part is arranged on the outer wall of the tip end of the core rod, the core rod reinforcement part is tightly attached to the inner wall of the die, a feeding gap is formed between the core rod reinforcement parts, and materials flow to a discharge hole through the inner wall of the die along the guide action of the core rod reinforcement part.

Furthermore, the core rod reinforcement part is annularly arranged by taking the air outlet channel as a center.

Furthermore, the core rod reinforcement parts are uniformly distributed.

Further, the discharge hole is an annular gap formed between the gas outlet channel and a discharge head of the neck mold.

Further, the length of the core rod reinforcement part is not more than that of the inner wall of the neck ring mold.

Furthermore, the core rod reinforcement part is a reinforcement strip or a reinforcement block.

The utility model has the advantages that:

compared with the traditional extruded pipe, the fixed relative position of the neck ring mold and the core rod is ensured by using the matched tool of the neck ring mold core rod, the concentricity is higher when the neck ring mold and the core rod are designed, the concentricity of the extruded expanding pipe can be ensured (other factors are eliminated), the manual operation process is simplified, and the time and the labor are saved.

Detailed Description

The technical solution of the present invention is further explained by the following specific examples.

As shown in fig. 1-5, the medical expanded pipe orifice die core rod matching tool comprises a die 7 and a core rod 8, wherein a core rod reinforcement part 1 is arranged on the outer wall of the tip end 3 of the core rod, the core rod reinforcement part 1 is tightly attached to the inner wall 2 of the die, a feeding gap 6 is formed between the core rod reinforcement parts 1, materials flow to a discharge port 10 along the inner wall 2 of the die after being guided by the core rod reinforcement part 1, and the discharge port 10 is an annular gap formed between an air outlet channel 5 and a discharge head 11.

The core rod reinforcement parts 1 are annularly arranged by taking the air inlet 5 as the center, and the core rod reinforcement parts 1 are uniformly distributed, so that the core rod reinforcement parts 1 have a better guiding effect on materials.

The length of the core rod reinforcement part 1 is not more than that of the inner wall 2 of the neck ring mold, so that the guiding effect on materials is ensured.

The core rod reinforcement part 1 is a reinforcement strip or a reinforcement block, preferably, the section of the reinforcement strip or the reinforcement block can be circular or polygonal, and the core rod reinforcement part is convenient to be better attached to the inner wall 2 of the neck ring mold.

The working process is as follows:

the utility model discloses a key is that bush and plug assembly back plug add muscle position 1 and the inseparable laminating of bush inner wall 2, bush inner wall 2 and the most advanced 3 outer wall rigidity of plug, when extruding the expansion pipe, at first let in gas with air inlet 5 department, gas lets in the passageway in proper order, and the material under the molten condition gets into supporting frock along feed inlet 4, hugs closely the plug through feeding clearance 6 and adds muscle position 1 and flow from bush inner wall 2 at last, and the expansion pipe concentricity has been confirmed this moment.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
