Description

Technical Field

[0001] The utility model relates to the technical field of mold design and manufacturing, in particular to a medical atomizer nozzle mold. Background Art

[0002] Moulds are various molds and tools used in industrial production to obtain the desired products by cooling, blow molding, extrusion, die casting or forging, smelting, stamping and other methods; in short, moulds are tools used to make shaped objects. Such tools are composed of various parts, and different moulds are composed of different parts; they mainly realize the processing of the shape of objects by changing the physical state of the formed materials. However, most of the moulds for nozzle products on the market are directly die-cast. However, for delicate products such as nozzles, it is necessary to make their detailed bevels, arcs, various angles, etc. meet the specified standards, otherwise the products produced will be far from meeting the qualified standards, and the material costs will be wasted in a time-consuming and labor-intensive manner.

[0003] At present, an existing nozzle mold (such as patent number: CN215431470U) discloses a nozzle mold, wherein the inner mold is arranged inside the outer mold, and the inner mold and the outer mold are detachable and assembled; the product is arranged in the inner mold and contacts with the inner surface of the inner mold, and one end of the product contacts and is fixed with the outer mold; the utility model is fixed by the outer mold, and the inner mold is more finely limited by the contact between the inclined surface, arc surface, various angles, etc. of the product, so that the precision of the product made by the utility model is higher and more accurate; and the detachable assembly of the inner mold and the outer mold greatly reduces the cost of later maintenance and repair of the utility model.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. The existing device is not provided with a mounting structure. Atomizer nozzles used in the medical field often need to be equipped with additional devices such as monitoring equipment and clamping equipment to assist in operations such as those required for bronchial diseases. The existing mold does not leave a position for mounting these auxiliary devices, so most of the atomizer nozzles produced only have an atomization function and are not easy to cooperate with auxiliary equipment for medical operations.

[0006] 2. The existing device is produced by die-casting, and the production speed is indeed very fast. However, because medical nozzles need to go deep into the human body and come into contact with some body organs, in order to prevent the production of toxins, most of them use some special polymer materials, such as polytetrafluoroethylene (PTFE) and polyetheretherketone (PEEK). Some of these materials have low plasticity and are not suitable for die-casting production. Therefore, the existing device has the problem of few applicable production scenarios.
