Description

A kind of novel sacculus molding equipment

Technical field

The utility model belongs to technical field of medical equipment, more particularly to a kind of novel sacculus molding equipment.

Background technique

Foley's tube is the key that human vas and other lumens are dredged and widely used bracket conveying equipment, and ball Capsule is the part of most critical on foley's tube.Sacculus generally requires high anti-burst performance, while requiring thin-walled, soft It is soft, it is foldable.Meet these requirements, not requiring nothing more than the polymer material used has extremely strong mechanical and physical character, simultaneously Very high requirement is proposed to moulding process.In order to meet technique requirement, the offer heating of the necessary precise and high efficiency of molding equipment adds Pressure, and speed and displacement are adjusted on a large scale, it is also necessary to accurate temperature and pressure control is provided.Efficient heating cooling system System and flexible transmission system are always the target of sacculus molding equipment research and development.The more commonly used technology of sacculus molding equipment at present It include: heating coolant jacket, mold, high pressure nitrogen feed system, clamping and transmission system.

The polymer tubing of extrusion molding first has to carry out both ends stretching in the prior art, in order to pass through mold stomidium. This process needs an other individual stretcher.Most crucial part is that heating is cold inside existing sacculus molding equipment But it covers.The interlayer of heating coolant jacket installs several electrically heated rods to meet the needs of rapid and uniform heating, while interlayer space is cold Directly logical cooling water heats the core installation mold of coolant jacket to be rapidly cooled to mold when but.It is logical to heat coolant jacket Mold is crossed to heat internal conduit, after conduit softening, the inflation and both ends collet of the high pressure nitrogen of catheter interior Under the collective effect of stretching, conduit is by inflation and is adjacent to mould inner wall formation sacculus.Later by heat-insulation pressure keeping be formed, then into Enter cooling and shaping and then completes sacculus forming process.

Heating coolant jacket bulky first has to pass through in each molding cycle is heated to forming temperature by room temperature, warp Heat preservation is crossed, is then cooled to the process of room temperature again.Due to heating the volume of coolant jacket itself, in addition mold, system has larger Thermal inertia, this just fundamentally limits molding efficiency, and sacculus is bigger, heating coolant jacket it is also bigger, thermal inertia It is bigger, to cause the heating in sacculus forming process unevenly slow with heating cooling velocity, and then lead to sacculus shaping efficiency Lowly；Secondly, to the sacculus of different-diameter and length, it is necessary to which, using the heating coolant jacket of corresponding size, this just needs user to purchase Many various sizes of heating coolant jackets are bought, so that the after-cost of equipment is high.
