Description

Technical Field

[0001] This utility model relates to the technical field of gift box lining molds, specifically a gift box lining forming mold. Background Technology

[0002] The proportion of gift box products in the current cosmetics market continues to increase. Consumers generally have higher demands for the exquisite appearance of gift boxes and the protection of the contents. This has driven the industry to adopt packaging liners that are customized according to the size of the contents. These liners need to be precisely matched and fitted to cosmetic bottles, jars, tools, etc. This usage and design result in a variety of structural forms and complicated size specifications. At the production line end, due to the high degree of customization and large structural differences of the inner lining, the existing automated equipment is difficult to achieve universal production. The inner lining production process is still mainly done by manual folding. Manual folding results in limited operation speed and low production efficiency. On the other hand, since the inner lining design is usually quite small, errors such as crease deviation and component misalignment are prone to occur during manual folding, which directly leads to a significant increase in the defect rate, which increases production costs and affects product delivery cycle and market competitiveness. Utility Model Content

[0003] The purpose of this utility model is to provide a gift box lining forming mold to solve the problems mentioned in the background art, such as low efficiency and easy damage of manual box folding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gift box liner forming mold, including a bottom mold, a clamping mold, and a top mold. The clamping mold is suspended above the bottom mold, and the top mold is suspended above the clamping mold. A top liner plate is fixedly inserted into the outer surface of the top mold, and the outer surface of the top liner plate penetrates the outer surface of the clamping mold. The clamping mold and the top liner plate are slidably connected. A folding hole is opened on the outer surface of the bottom mold, and the top liner plate passes through the folding hole. The clamping mold and the top liner plate are slidably connected, and the top liner plate does not fit against the outer surface of the folding hole.

[0005] Preferably, positioning holes are provided on both outer surfaces of the bottom mold, and the outer surfaces of the positioning holes are chamfered. Positioning pins are fixedly installed on both outer surfaces of the clamping mold, and the positioning pins are inserted into the positioning holes.

[0006] By adopting the above technical solution, the bottom mold and the clamping mold can be accurately inserted and fixed together through the chamfering of the positioning hole and the insertion of the positioning pin, so that the bottom mold and the clamping mold can be more accurate when they are combined, and the pressing and folding accuracy of the inner lining cardboard can be further improved.

[0007] Preferably, side positioning plates are inserted and installed on the outer surfaces of both ends of the bottom mold, and the side positioning plates are L-shaped. An inner lining cardboard is placed on the outer surface of the bottom mold, and the outer surfaces of both sides of the inner lining cardboard are in contact with the outer surfaces of the side positioning plates.

[0008] By adopting the above technical solution, the two sides of the inner lining cardboard can be accurately positioned by the side positioning plate, making it more convenient for workers to place the inner lining cardboard and ensuring the accuracy of the inner lining cardboard on the bottom mold, thereby improving the efficiency of placing the inner lining cardboard.

[0009] Preferably, a positioning top plate is inserted and installed on the outer surface of the bottom mold, and the positioning top plate is located between the side positioning plates. The outer surface of the positioning top plate is in contact with the outer surface of the inner lining cardboard, and the outer surfaces of the positioning top plate and the side positioning plates are not in contact with the outer surface of the clamping mold.

[0010] By adopting the above technical solution, the insertion depth of the inner lining cardboard can be limited by the positioning top plate, which further improves the accuracy of placing the inner lining cardboard on the bottom mold and reduces the folding defects caused by inaccurate placement of the inner lining cardboard when folding the box.

[0011] Preferably, the clamping mold has an installation hole on the side away from the bottom mold, and the installation hole is designed in the shape of a cap. An expansion plug is inserted into the installation hole and engages with the installation hole. An elastic sliding mechanism is provided between the clamping mold and the top mold.

[0012] By adopting the above technical solution, the cap-shaped design of the mounting hole allows the expansion plug to be firmly connected to the mounting hole after it is inserted into the mounting hole. This reduces the risk of the expansion plug becoming disengaged from the mounting hole due to excessive movement during later use, and improves the connection between the mounting hole and the expansion plug.

[0013] Preferably, the elastic sliding mechanism includes: a bolt that penetrates the outer surface of the top mold and is slidably connected to the top mold; the bolt and the expansion plug are threadedly connected and a spring is provided between the expansion plug and the top mold.

[0014] By using the above technical solution, bolts are screwed into the interior of the expansion plug, allowing the expansion plug to deform and further lock into the mounting hole. The bolts limit the clamping mold, and the springs push the clamping mold away, allowing the top mold to automatically reset after being pressed down. The top liner plate can also automatically reset after the operation is completed, greatly improving the convenience of folding the inner cardboard box.

[0015] Preferably, a positioning post is installed through the outer surface of the top mold and the top liner plate, and the two ends of the positioning post are parallel to the two outer surfaces of the top mold. A wedge-shaped surface is provided at the end of the top liner plate near the bottom mold, and the wedge-shaped surface is not parallel to the folding hole.

[0016] By adopting the above technical solution, the top liner can be limited at one time by the positioning column, so that the top liner will not fall off due to jamming during the pressing of the inner liner. The wedge-shaped surface design makes it easier for the top liner to break open the opening of the inner liner and insert into the folding hole, which greatly improves the smoothness and efficiency of the wedge breaking the inner liner and inserting it into the folding hole, and reduces the top liner falling off due to jamming or other reasons.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the gift box lining molding mold: 1. Place the inner lining cardboard to be folded into the outer surface of the bottom mold and position it. Then, press down the top mold so that the top lining plate can move along with it and pass through the clamping mold. The top lining plate can push open the outer surface of the inner lining cardboard and insert it into the folding hole. Through the compression of the top lining plate and the folding hole, the inner lining cardboard can be pressed into shape in one go, without the need for workers to fold and compress the holes on the outer surface of the inner lining cardboard one by one, which greatly improves the efficiency of folding inner lining cardboard into boxes. 2. When the inner lining cardboard is placed on the outer surface of the bottom mold, both sides of the inner lining cardboard will be in contact with the outer surface of the side positioning plate, and one end of the outer surface of the inner lining cardboard will be in contact with the outer surface of the positioning top plate, so that the inner lining cardboard can be quickly positioned on the bottom mold, reducing the positioning time required for the positioning top plate to be placed on the bottom mold, and improving the accuracy and efficiency of placing the inner lining cardboard. 3. As the clamping mold and top mold press down, they clamp the inner lining cardboard, ensuring its outer surface remains flat when pressed by the top liner plate. This allows the top mold to move closer to the clamping mold, enabling the top liner plate to break open the outer surface of the inner lining cardboard. When the top mold resets, it is pushed by a spring and its movement is reset by bolts, allowing the inner lining cardboard to automatically reset after the folding process is complete. This facilitates the removal of the inner lining cardboard from the bottom mold, greatly improving convenience and efficiency during use. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a gift box liner forming mold, including a bottom mold 1, a clamping mold 2, and a top mold 3. The clamping mold 2 is suspended above the bottom mold 1, and the top mold 3 is suspended above the clamping mold 2. Positioning holes 4 are respectively opened on the outer surfaces of both sides of the bottom mold 1, and the outer surfaces of the positioning holes 4 are chamfered. Side positioning plates 5 are inserted and installed on the outer surfaces of both ends of the bottom mold 1, and the side positioning plates 5 are designed in an L shape. Inner liner cardboard 16 is placed on the outer surface of the bottom mold 1, and the outer surfaces of both sides of the inner liner cardboard 16 are in contact with the outer surfaces of the side positioning plates 5. A positioning top plate 6 is inserted and installed on the outer surface of the bottom mold 1, and the positioning top plate 6 is located between the side positioning plates 5. The outer surface of the positioning top plate 6 is in contact with the outer surface of the inner liner cardboard 16, and the outer surfaces of the positioning top plate 6 and the side positioning plates 5 are not in contact with the outer surface of the clamping mold 2.

[0022] Firstly, when using it, simply place the inner lining cardboard 16 and insert it into the outer surface of the bottom mold 1, so that the outer surfaces of both sides of the inner lining cardboard 16 can fit against the outer surface of the side positioning plate 5, and one end of the inner lining cardboard 16 fits against the outer surface of the positioning top plate 6, so that the inner lining cardboard 16 can be quickly positioned and placed, greatly improving the convenience and efficiency of placing the inner lining cardboard 16 in the molding mold.

[0023] Positioning pins 7 are fixedly installed on both outer surfaces of the clamping mold 2, and the positioning pins 7 are inserted into the positioning holes 4. A top liner plate 12 is fixedly installed on the outer surface of the top mold 3, and the outer surface of the top liner plate 12 penetrates the outer surface of the clamping mold 2. The clamping mold 2 and the top liner plate 12 are slidably connected. A folding hole 15 is opened on the outer surface of the bottom mold 1, and the folding hole 15 is passed through by the top liner plate 12. The clamping mold 2 and the top liner plate 12 are slidably connected, and the top liner plate 12 does not fit against the outer surface of the folding hole 15. A wedge-shaped surface 14 is provided at one end of the top liner plate 12 near the bottom mold 1, and the wedge-shaped surface 14 is not parallel to the folding hole 15.

[0024] Secondly, by pressing down the top mold 3, the clamping mold 2 can be brought closer to the bottom mold 1, and the positioning pin 7 can be inserted into the positioning hole 4 to position the bottom mold 1 and the clamping mold 2. The downward movement of the top mold 3 can drive the top liner plate 12 to move together and be inserted into the folding hole 15, so that the inner liner cardboard 16 can be pushed open by the top liner plate 12. The wedge surface 14 makes it easier to break the inner liner cardboard 16, making it easier to push open the inner liner cardboard 16, and allowing the inner liner cardboard 16 to be accurately folded into a box, greatly reducing the chance of damage to the inner liner cardboard 16 when folding the box, and further improving the efficiency of folding the box.

[0025] The clamping mold 2 has an installation hole 8 on the side away from the bottom mold 1. The installation hole 8 is designed in the shape of a cap. A expansion plug 9 is inserted into the installation hole 8 and engages with the installation hole 8. An elastic sliding mechanism is provided between the clamping mold 2 and the top mold 3. The elastic sliding mechanism includes a bolt 10, which penetrates the outer surface of the top mold 3 and is slidably connected to the top mold 3. The bolt 10 is threadedly connected to the expansion plug 9 and a spring 11 is provided between the expansion plug 9 and the top mold 3.

[0026] Furthermore, by inserting the expansion plug 9 into the mounting hole 8 and screwing in the bolt 10, the strength of the connection between the bolt 10 and the clamping mold 2 can be effectively improved. At the same time, the setting of the spring 11 can enable the top mold 3 to automatically push the clamping mold 2 to reset after resetting, so that the top liner plate 12 can automatically retract into the clamping mold 2. After the inner liner cardboard 16 is pressed and folded into a box, the clamping mold 2 can automatically reset. The clamping mold 2 and the bottom mold 1 can clamp the inner liner cardboard 16, so that the inner liner cardboard 16 can remain flat when the top liner plate 12 passes through it, further reducing the probability of damage to the inner liner cardboard 16 and making it easier to remove the pressed inner liner cardboard 16, greatly improving the convenience of mold use.

[0027] Positioning pins 13 are installed through the outer surfaces of the top mold 3 and the top liner plate 12, and the two ends of the positioning pins 13 are parallel to the two outer surfaces of the top mold 3.

[0028] Furthermore, by inserting the positioning pin 13 into the top mold 3 and the top liner plate 12, the connection strength between the top liner plate 12 and the top mold 3 can be effectively strengthened, so that the top liner plate 12 will not fall off due to jamming or other reasons when it moves inside the clamping mold 2, which greatly improves the stability during use.

[0029] Working principle: In use, simply place the inner lining cardboard 16 on the outer surface of the bottom mold 1, so that the two sides and top of the inner lining cardboard 16 can be attached to the outer surfaces of the side positioning plate 5 and the positioning top plate 6 respectively. Then, press down the top mold 3 and the clamping mold 2 so that the positioning pin 7 can be inserted into the positioning hole 4, so that the bottom mold 1 and the clamping mold 2 can be quickly positioned and the inner lining cardboard 16 can be clamped by the bottom mold 1 and the clamping mold 2, so that the top lining plate 12 can continue to move down and pass through the inner lining cardboard 16. With the top lining plate 12 inserted into the folding hole 15 and the use of the wedge surface 14, the inner lining cardboard 16 can be inserted more easily by the top lining plate 12, which greatly improves the efficiency of folding the inner lining cardboard 16 and reduces the generation of defective products.

[0030] 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.
