Description

Technical Field

[0001] This utility model relates to the field of aluminum can manufacturing technology, specifically to a high-pressure resistant aluminum can and its manufacturing mold. Background Technology

[0002] Metal packaging cans are widely used packaging containers in various industries for holding beverages, wines, etc. Metal packaging cans include those made of steel, iron, and aluminum. Steel cans are heavy and inconvenient to carry, while iron cans have relatively poor pressure resistance and are prone to rust and corrosion. Therefore, aluminum cans are now the most commonly used. However, current aluminum cans have low external pressure resistance and are easily deformed under external pressure. Some manufacturers have added horizontal annular ribs to the outside of the can, but these ribs create annular grooves on the inner wall of the can, affecting the discharge of materials inside the can. To solve this problem, some manufacturers add an inner liner inside the can to make the inner wall of the can smooth, but this increases the cost of the can.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a high-pressure resistant aluminum can and its manufacturing mold. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a high-pressure resistant aluminum can and its manufacturing mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure resistant aluminum can and its manufacturing mold, comprising a cylindrical aluminum can body, a can opening, a can lid and a can lid tear ring, wherein a plurality of convex ribs are equidistantly arranged on the outer wall of the aluminum can body, the convex ribs are integrally stamped with the aluminum can body, the convex ribs are vertically arranged on the aluminum can body and the convex ribs have a semi-circular structure.

[0006] Furthermore, an aluminum bottom plate is placed at the inner bottom of the aluminum can body. The diameter of the aluminum bottom plate is the same as the inner diameter of the aluminum can body, and the outer wall of the aluminum bottom plate is provided with semi-circular protrusions at equal intervals, which are the same number as the protruding ribs. The semi-circular protrusions are located in the grooves formed by the protruding ribs inside the aluminum can body.

[0007] Furthermore, a pull rod is fixed to the center of the side of the aluminum base plate facing the opening of the aluminum can body.

[0008] Furthermore, a sleeve is movably sleeved at the end of the pull rod, and a semi-circular baffle is fixed at the end of the sleeve. The baffle is flush with the opening of the aluminum can after installation, and the diameter of the baffle is the same as the inner diameter of the aluminum can.

[0009] Another object of the present invention is to provide a mold for a high-pressure resistant aluminum can, the mold comprising an aluminum can body stamping mold and an aluminum bottom sheet stamping mold.

[0010] Furthermore, the aluminum can body stamping die includes an outer die and a core die. The inner wall of the outer die is provided with vertical semi-circular grooves at equal intervals, and the outer wall of the core die is provided with a number of ribs at equal intervals corresponding to the semi-circular grooves.

[0011] Furthermore, the aluminum sheet stamping die includes a lower die and an upper die. The bottom of the lower die has a base plate. Several semi-circular grooves are equidistantly arranged on the outer ring of the lower die. A round rod is provided in the middle of the upper end face of the lower die. Several semi-circular protrusions corresponding to the semi-circular grooves are equidistantly arranged on the outer periphery of the bottom of the upper die. A through groove is provided at the midpoint of the upper die for the round rod to pass through the upper die.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The aluminum can is equipped with vertical ribs on the outside, and the ribs are integrally stamped with the aluminum can body. This not only increases the pressure-bearing capacity of the aluminum can, but also the vertical arrangement of the ribs makes the rib grooves inside the can also vertical, which does not affect the discharge of the internal material. This eliminates the need to add a smooth inner liner to the can. In addition, a bottom plate is added inside the can, which can be lifted upwards, which can better facilitate the discharge of viscous non-liquid materials inside the can.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figure 1-5 A high-pressure resistant aluminum can includes a cylindrical aluminum can body 1, a notch 3, a can lid 4, and a can lid tear-off ring 5. The can lid 4 is located inside the notch 3. The above structure is consistent with the aluminum can in the prior art, and will not be described in detail here. Several ribs 2 are equidistantly arranged on the outer wall of the aluminum can body 1. The ribs 2 are integrally stamped with the aluminum can body 1. The ribs 2 are arranged vertically on the aluminum can body 1 and have a semi-circular structure. The presence of the ribs 2 forms a vertical semi-circular groove on the inner wall of the aluminum can body 1, that is, the opening of the semi-circular groove faces the opening of the aluminum can body 1. In this way, when liquid materials and solid materials are stored inside the aluminum can body 1, the materials in the vertical semi-circular groove will automatically flow out along it and will not remain inside.

[0028] For viscous non-liquid materials, discharge is difficult, especially with the addition of a vertical semi-circular groove, which increases the adhesion area and makes discharge more difficult. To address this, an aluminum bottom plate 6 is placed at the inner bottom of the aluminum can body 1. The diameter of the aluminum bottom plate 6 is the same as the inner diameter of the aluminum can body 1, and the outer wall of the aluminum bottom plate 6 is provided with semi-circular protrusions at equal intervals, matching the number of protruding ribs 2. The semi-circular protrusions are located in the grooves formed by the protruding ribs 2 inside the aluminum can body 1, meaning the aluminum bottom plate 6 is located at the inner bottom of the aluminum can body 1. For the material remaining at the inner bottom of the aluminum can body 1 and in the vertical semi-circular groove, the aluminum bottom plate 6 can be used to push it out. Simply pull the lever to allow the material in the aluminum can body 1 to be discharged more cleanly.

[0029] In addition, a sleeve 8 is movably sleeved at the end of the pull rod 7, and a semi-circular baffle 9 is fixed at the end of the sleeve 8. The position of the baffle 9 after installation is flush with the opening of the aluminum can body 1. The diameter of the baffle 9 is the same as the inner diameter of the aluminum can body 1. The side of the baffle 9 facing the opening of the aluminum can has a protrusion. That is, when the material in the aluminum can is not completely taken out at once, the can lid 4 is usually opened halfway. In this way, pushing the protrusion with a finger can make the baffle 9 rotate, and the baffle 9 can be used to cover the opened part.

[0030] Please see Figure 6-10 A mold for manufacturing the aforementioned high-pressure resistant aluminum can, the mold comprising an aluminum can body stamping mold and an aluminum bottom sheet stamping mold.

[0031] The aluminum can body stamping die includes an outer mold 10 and a core mold 11. The inner wall of the outer mold 10 is provided with vertical semi-circular grooves at equal intervals. The outer wall of the core mold 11 is provided with several ribs at equal intervals that correspond one-to-one with the semi-circular grooves. During manufacturing, an aluminum disc is placed into the outer mold 10, and the core mold 11 is pushed into the outer mold 10 by hydraulic drive, thus forming the aluminum can body 1.

[0032] The aluminum base sheet stamping die includes a lower die 13 and an upper die 15. The bottom of the lower die 13 has a base plate 12. Several semi-circular grooves are evenly spaced on the outer ring of the lower die 13. A round rod 14 is provided in the middle of the upper end face of the lower die 13. Several semi-circular protrusions 16, corresponding to the semi-circular grooves, are evenly spaced on the bottom periphery of the upper die 15. A through groove is provided at the midpoint of the upper die 15 for the round rod 14 to pass through the upper die 15. The aluminum disc is placed on the lower die 13, and the upper die 15 is pushed down to the lower die 13. The semi-circular protrusions 16 of the upper die 15 enter the semi-circular grooves of the lower die 13, thus forming a preliminary aluminum base sheet 6. The preliminary aluminum base sheet 6 is then trimmed and polished to form the finished aluminum base sheet 6 and the pull rod 14.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
