Description

Technical Field

[0001] The utility model relates to the technical field of tooling molds, and particularly relates to a tooling mold for columnar micro glass containers. Background Art

[0002] For some columnar objects, especially those with a relatively small diameter, when processing or filling them, due to their slender characteristics, they are prone to tipping over under the action of their own bottom structure and external forces when in an upright state. Therefore, when operating such columnar objects, corresponding tooling molds are often required to clamp or limit them. However, for some columnar objects with a very large usage amount, the inner holes in the tooling molds for placing the columnar objects are easily worn and enlarged, resulting in a deteriorated effect of the tooling mold, such as problems like tilting of the placed columnar objects.

[0003] Therefore, the researchers of the applicant believe that it is necessary to improve or optimize the tooling mold for installing or placing columnar objects. Summary of the Invention

[0004] In practice, the researchers of the applicant invented a new micro glass container, which is preferably used to hold preparations, especially medical or pharmaceutical preparations, particularly biological or chemical preparations; the volume of the micro glass container is not more than 0.8 ml or not more than 0.5 ml, and even can be not more than 0.2 ml. The micro glass container is columnar and its outer diameter is not more than 8 mm or 6 mm (the inner diameter for holding the preparation is smaller). When filling the micro glass container, due to its small diameter, it is difficult to maintain self - standing and stable positioning by itself. Therefore, a special tooling mold is needed to place the micro glass container. However, since the tooling mold needs to continuously place micro glass containers during work, the inner hole of the tooling mold for placing the micro glass container is easily worn, and after the inner hole is worn, some adverse effects such as shaking and yawing will occur.

[0005] The purpose of the utility model includes providing a tooling mold that can adapt to the above - mentioned micro glass container, so that its inner hole can still be used normally after being worn by a certain amount.

[0006] To this end, the utility model relates to a tooling mold for columnar micro glass containers, including:

[0007] A columnar body, the top of which has a semi - cylindrical section, and the upper part of the semi - cylindrical section has a first semi - circular hole;

[0008] A semi-cylinder, arranged coaxially and face-to-face with the semi-cylindrical section, having a second semi-circular hole thereon, and the second semi-circular hole and the first semi-circular hole form an inner mold hole for accommodating the columnar micro glass container, and the depth of the inner mold hole is less than the height of the semi-cylinder;

[0009] A pre-tightening member for pre-tightening the semi-cylinder on the semi-cylindrical section.

[0010] Preferably, the columnar body has a central through hole that penetrates up and down and is coaxial with the first semi-circular hole, the central through hole extends to communicate with the first semi-circular hole, and the diameter of the central through hole is less than the diameter of the inner mold hole.

[0011] Preferably, the semi-cylinder has a third semi-circular hole, the third semi-circular hole is coaxial with the second semi-circular hole, and the diameter is less than that of the second semi-circular hole. The third semi-circular hole has the same diameter as the central through hole.

[0012] Preferably, one side or both sides of the middle of the semi-cylinder have semi-circular protrusions, and the semi-cylindrical section has corresponding semi-circular depressions.

[0013] Preferably, one side or both sides of the middle of the semi-cylindrical section have semi-circular protrusions, and the semi-cylinder has corresponding semi-circular depressions.

[0014] Preferably, the gap between the semi-cylinder and the semi-cylindrical section is not greater than 0.5 mm, preferably not greater than 0.2 mm, and further preferably not greater than 0.1 mm.

[0015] Preferably, the top of the semi-cylinder is flush or not flush with the top of the semi-cylindrical section.

[0016] Preferably, the pre-tightening member includes at least one rubber ring, and the semi-cylindrical section and the semi-cylinder have annular grooves for accommodating at least a part of the rubber ring, and the annular grooves include a first annular groove section on the semi-cylindrical section and a second annular groove section on the semi-cylinder.

[0017] Preferably, the pre-tightening member includes at least two rubber rings, and the semi-cylindrical section and the semi-cylinder have at least two annular grooves for accommodating at least a part of the rubber ring, and the annular grooves include a first annular groove section on the semi-cylindrical section and a second annular groove section on the semi-cylinder.

[0018] Preferably, the annular groove is used to accommodate at least most or all of the rubber ring.

[0019] Preferably, the mouth of the inner mold hole has a chamfer or a fillet, or a combination of a chamfer and a fillet.

[0020] Compared with the above background art, the beneficial effects of the present utility model are generally as follows.

[0021] A tooling die for a columnar micro glass container provided by the present utility model includes a columnar body, a semi-cylindrical body, and a pre-tightening member. The top of the columnar body has a semi-cylindrical section, and the upper part of the semi-cylindrical section has a first semi-circular hole. The semi-cylindrical body is coaxial and face-to-face with the semi-cylindrical section, and the semi-cylindrical body has a second semi-circular hole. The second semi-circular hole and the first semi-circular hole form an inner die hole for accommodating the columnar micro glass container. The depth of the inner die hole is less than the height of the semi-cylindrical body. The pre-tightening member is used to pre-tighten the semi-cylindrical body on the semi-cylindrical section. After the inner die hole is worn and enlarged, the pre-tightening member will move the semi-cylindrical body further towards the semi-cylindrical section, so that the columnar micro glass container can still be stably placed in the inner die hole, thereby greatly (doubling) extending the service life of the tooling die. In addition, the setting of the central through hole can enable the liquid leakage caused by accidents or other situations to flow down and will not remain in the inner die hole for a long time.

[0029] In order to enable those skilled in the art to better understand the various technical solutions involved in the present utility model, the following further detailed description of the present utility model will be given in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments in the present application and the various specific technical features described in the embodiments can be combined in any suitable manner; in order to avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods, as long as they do not violate the idea of the present utility model, they should also be regarded as the content disclosed by the present utility model.

[0030] In a specific embodiment, as Figures 1 to 4 shown, a tooling mold for a columnar micro glass container provided by the present utility model includes a columnar body 10, semi-cylindrical bodies 20, and a pre-tightening member 30. The top of the columnar body 10 has a semi-cylindrical section 11, and the upper part of the semi-cylindrical section 11 has a first semi-circular hole 12; the semi-cylindrical bodies 20 are coaxial with and arranged face to face with the semi-cylindrical section 11. The semi-cylindrical bodies 20 have second semi-circular holes 21, and the second semi-circular holes 21 and the first semi-circular holes 12 form an inner mold hole 40 for accommodating the columnar micro glass container 08. The depth of the inner mold hole 40 is less than the height of the semi-cylindrical bodies 20; the pre-tightening member 30 is used to pre-tighten the semi-cylindrical bodies 20 on the semi-cylindrical section 11.

[0031] Among them, it should be noted that the semi-cylindrical bodies 20 and the semi-cylindrical section 11 are arranged face to face, which means that the rectangular surfaces of the semi-cylindrical bodies 20 and the semi-cylindrical section 11 are parallel to each other or substantially parallel, but there is a distance between them. As Figure 5 shown, it is a top view schematic diagram of two semi-cylindrical bodies arranged face to face. The arrangement of the semi-cylindrical body 06 and the semi-cylindrical body 07 is a typical face-to-face arrangement, and the rectangular surfaces between them are parallel to each other. In addition, the two rectangular surfaces may not be completely parallel, but it is sufficient that they do not contact each other around (substantially parallel).

[0032] As Figures 1 to 4 shown, the columnar micro glass containers 08 all have relatively small necks. In addition, they may also have no necks and are columnar with the same diameter from top to bottom.

[0033] As Figure 3 and Figure 4 shown, the columnar body 10 has a central through hole 13 that penetrates up and down and is coaxial with the first semi-circular hole 12. The central through hole 13 extends to communicate with the first semi-circular hole 12, and the diameter of the central through hole 13 is smaller than the diameter of the inner mold hole 40.

[0034] As Figure 3 and Figure 4 shown, the semi-cylindrical body 20 has a third semi-circular hole 24, which is coaxial with the second semi-circular hole 21 and has a diameter smaller than that of the second semi-circular hole 21. The third semi-circular hole 24 has the same diameter as the central through-hole 13. Of course, the third semi-circular hole 24 can also be omitted on the premise that the central through-hole 13 extends to communicate with the first semi-circular hole 12.

[0035] As Figure 1 and Figure 4 shown, semi-circular protrusions 22 are provided on both sides of the middle part of the semi-cylindrical body 20, and corresponding semi-circular depressions 14 are provided on the semi-cylindrical section 11. With this structure, when the columnar micro glass container 08 placed in the inner die hole 40 is withdrawn, the semi-cylindrical body 20 will not be withdrawn due to the influence of friction or other factors, and the position limiting effect of the semi-cylindrical body 20 is better.

[0036] In addition, referring to Figure 1 and Figure 4 shown, the semi-circular protrusions 22 can also be provided only on one side of the semi-cylindrical body 20, that is, only one is provided, and the corresponding semi-circular depression 14 is also provided only one. In addition, the relative positions of the semi-circular protrusions 22 and the semi-circular depressions 14 can be interchanged. For example, the semi-circular protrusions 22 can be provided on the semi-cylindrical section 11, while the semi-circular depressions 14 are provided on the semi-cylindrical body 20, and the same function can be achieved.

[0037] Referring to Figures 1 to 4 shown, in one embodiment, the gap between the semi-cylindrical body 20 and the semi-cylindrical section 11 is not greater than 0.5 mm. In a preferred embodiment, the gap between the semi-cylindrical body 20 and the semi-cylindrical section 11 is not greater than 0.2 mm. In a preferred embodiment, the gap between the semi-cylindrical body 20 and the semi-cylindrical section 11 is not greater than 0.1 mm. This gap should not be too large or too small. If it is too large, it means the pre-tightening force will be too large, and if it is too small, the effect of extending its service life will not be particularly prominent. Therefore, in a specific embodiment, the gap is selected as 0.15 mm or 0.07 mm.

[0038] Referring to Figures 1 to 4 shown, the top of the semi-cylindrical body 20 is flush with the top of the semi-cylindrical section 11. In addition, it can also be non-flush.

[0039] As Figure 2As shown, the pre-tightening member 30 includes two rubber rings 31 and two annular grooves 32. One rubber ring 31 is sleeved in each annular groove 32. The rubber ring 31 is completely accommodated in the annular groove 32, or it can also be partially (mostly or a small part) accommodated in the annular groove 32. The annular grooves 32 are distributed on the semi-cylindrical section 11 and the semi-cylindrical body 20. The first annular groove section 15 is distributed on the semi-cylindrical section 11, and the second annular groove section 23 is distributed on the semi-cylindrical body 20. In addition, both the annular groove 32 and the rubber ring 31 can be one, and its function can also be completed. Two can complete the function better. Additionally, it can also be three or more. Moreover, it can also be that the annular groove 32 is not provided and the rubber ring 31 is directly bonded to the semi-cylindrical section 11 and the semi-cylindrical body 20 by gluing to achieve the required function.

[0040] As Figure 3 and Figure 4 shown, the mouth of the inner die hole 40 has a chamfer 41. In addition, a fillet can be used instead, or a combination of a chamfer and a fillet. This is to facilitate the entry of the columnar micro glass container 08 into the inner die hole 41.

[0041] The above has introduced in detail a tooling die for a columnar micro glass container provided by the utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the utility model. The description of the above embodiments is only used to help understand the method and its core idea of the utility model, and for other parts not described in detail, they can generally be obtained according to relevant existing technologies. It should be noted that without departing from the principle of the utility model, those skilled in the art can know many alternative designs and embodiments for implementing the utility model within the scope of the appended claims.
