Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a special-shaped blank stamping die. Background Art

[0002] The traditional manufacturing process for shaped glass ornaments typically utilizes a technique known as "fusion molding." This technique first requires heating the raw glass powder above its melting point, transforming it into a fluid state with good flowability. The molten glass is then manually poured or blown into a pre-designed mold to achieve the desired shape. After cooling and solidification, the product undergoes subsequent grinding and polishing processes to obtain the finished shaped glass ornament.

[0003] However, this process has several major problems:

[0004] 1. Numerous processes: From the melting of glass powder to molding and then to later processing, the entire production process involves multiple steps, each of which requires precise control, resulting in low production efficiency.

[0005] 2. Low efficiency: Since the entire process mostly relies on manual operation, including the pouring and shaping of molten glass, as well as subsequent processing, these steps are difficult to automate, limiting the production speed and scale.

[0006] 3. Quality is difficult to unify: The uncertainty of manual operation may lead to differences in the quality of each product, making it difficult to ensure product consistency and standardization.

[0007] 4. Safety hazards: The operation of high-temperature molten glass is dangerous and requires high safety protection for operators, which increases the complexity and cost of production.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0034] The following combination Figures 1 to 7 The utility model describes a special-shaped blank punching die.

[0035] like Figures 1 to 7As shown, the utility model provides a special-shaped blank stamping die, including: a first template 1 and a second template 2, each end corner between the first template 1 and the second template 2 is connected by a column 3, a rotating shaft 4 is passed through the first template 1 and the second template 2, and a rotating seat 5 is passed through the rotating shaft 4, so that the rotating seat 5 rotates with the rotation of the rotating shaft 4, and a plurality of groups of first pressing needles 8 are arranged around the outer periphery of the rotating seat 5 through a first fixed ring 6, and a plurality of groups of second pressing needles 9 are arranged around the outer periphery of the rotating seat 5 through a second fixed ring 7, and each first pressing needle 8 and the second pressing needle 9 are arranged opposite to each other, and the opposite first pressing needles 8 and the second pressing needles 9 are arranged opposite to each other. A pressing needle 8 and a second pressing needle 9 cooperate to form a mold cavity 10. The first template 1 is connected to a guide seat 11. One end edge of the guide seat 11 is against the first pressing needle 8. The guide seat 11 is inclined toward one end edge of the first pressing needle 8, so that the first pressing needle 8 gradually fits toward the second pressing needle 9 as the rotating seat 5 rotates. The first template 1 is located at the inclined end of the guide seat 11 and is connected to a punching wheel assembly 12. The punching wheel assembly 12 is against the first pressing needle 8. The second template 2 is connected to a pressure wheel assembly 13 corresponding to the punching wheel assembly 12, and the pressure wheel assembly 13 is against the second pressing needle 9.

[0036] When the equipment is started, the rotating shaft 4 begins to rotate under the action of the driving force. Since the turntable 5 is passed through the rotating shaft 4, it will also rotate with the rotating shaft 4. As the turntable 5 rotates, the first fixed ring 6 and the second fixed ring 7 connected to the outer periphery of the turntable 5 rotate synchronously with the turntable 5. Through the punching wheel assembly 12, the first pressing needle 8 will be guided to move toward the second pressing needle 9. This opposite movement makes the first pressing needle 8 and the second pressing needle 9 gradually fit together, thereby forming a mold cavity 10 for forming the special-shaped blank.

[0037] The inclined end edge of the guide seat 11 contacts the first pressing pin 8, and because of its inclined setting, it can push the first pressing pin 8 to fit the second pressing pin 9 during the rotation of the rotating seat 5. This design ensures that the mold can be evenly pressed when closing.

[0038] When the first pressing needle 8 moves along the direction of the punching wheel assembly 12, so that one end of the first pressing needle 8 is completely fitted with the second pressing needle 9, the formed mold cavity 10 can punch and form the fluid material. The pressure wheel assembly 13 on the second template 2 provides support and bears pressure from the second pressing needle 9 to ensure the stability and forming accuracy of the mold.

[0039] This design uses a rotating punching method to quickly and efficiently form the material, avoiding the high-temperature treatment required in traditional melt molding methods, reducing energy consumption and potential safety risks. In addition, due to the precise control of the second upper punch 9 and the automated operation of the mold, production efficiency is improved and the consistency of product quality is also guaranteed.

[0040] The rotating base 5 is driven by the rotating shaft 4, so that the first pressing needle 8 is merged with the second pressing needle 9 when the rotating base 5 is rotating, thereby realizing the rapid molding of the special-shaped blank, reducing multiple processes in the traditional melt molding method, and improving production efficiency. The first fixing ring 6 and the second fixing ring 7 are driven by the rotating base 5 to realize the rotation of the first pressing needle 8 and the second pressing needle 9 around the rotating base 5. Through the guide seat 11 and the punching wheel assembly 12, the first pressing needle 8 is gradually translated toward the second pressing needle 9 in sequence. When the first pressing needle 8 and the second pressing needle 9 cooperate, the fluid-like glass can be punched to realize the rapid molding of the special-shaped blank. The design of the stamping die allows the entire production process to be automated, reducing dependence on manual operation, thereby improving production speed and scale, and reducing production costs. The precisely designed first pressing needle 8 and the second pressing needle 9 are arranged opposite to each other to form a mold cavity 10, thereby ensuring the consistency of shape and size of each product and improving the standardization of the product. It avoids the operation of manual shaping, reduces safety hazards in the production process, reduces the safety protection requirements for operators, and improves production safety.

[0041] Preferably, bearings 14 are installed between the rotating shaft 4 and the first mold plate 1, and between the rotating shaft 4 and the second mold plate 2. The primary function of bearings 14 is to reduce friction between two moving surfaces in direct contact. In this mold, bearings 14 ensure smooth rotation between the rotating shaft 4 and the first and second mold plates 1 and 2, reducing wear, thereby improving overall mechanical efficiency and extending the life of the equipment.

[0042] Preferably, the first fixing ring 6 and the second fixing ring 7 are respectively provided with a plurality of groups of through holes 15 in an array, and the first pressing needle 8 is movably inserted into the through hole 15 of the first fixing ring 6, and the second pressing needle 9 is movably inserted into the through hole 15 of the second fixing ring 7. When the pressing needle is worn or needs to be replaced, it can be quickly removed from the through hole 15 and replaced with a new one, which simplifies the maintenance and replacement process and reduces downtime.

[0043] Preferably, the first pressing needle 8 is located at one end of the first template 1 and is connected to the first pressing head 16, and the first pressing head 16 is in contact with the guide seat 11. The second pressing needle 9 is located at one end of the second template 2 and is connected to the second pressing head 17. The setting of the first pressing head 16 and the second pressing head 17 can reduce the wear of the first pressing needle 8 and the second pressing head 9.

[0044] Preferably, the guide seat 11 is connected to a first flush pressing seat 18, the end of the first flush pressing seat 18 is against the outer periphery of several first pressing needles 8, the inner side of the end of the first flush pressing seat 18 is against the first pressure head 16, and the inner side of the end pressed by the first flush pressing seat 18 is an inclined structure. The first flush seat is used to push the first pressure head 16 to move the first pressure needle 8 away from the second pressure needle 9, thereby realizing the separation of the first pressure needle 8 and the second pressure needle 9.

[0045] Preferably, the second template 2 is connected to a second flush press seat 19, the end of the second flush press seat 19 is against the outer periphery of several second pressing needles 9, the inner side of the end of the second flush press seat 19 is against the second pressure head 17, and the inner side of the end pressed by the second flush press seat 19 is an inclined structure. The second flush seat is used to push the second pressure head 17 to make the second pressure needle 9 move away from the first pressure needle 8, thereby realizing the separation of the second pressure needle 9 from the first pressure needle 8.

[0046] Preferably, a positioning seat 20 is also provided between the swivel seat 5 and the rotating shaft 4, and a piston structure is adopted between the swivel seat 5 and the positioning seat 20, and one end of the swivel seat 5 is connected to the positioning seat 20 through a first buffer spring 22. By adopting a piston structure between the swivel seat 5 and the positioning seat 20, and one end of the swivel seat 5 is connected to the positioning seat 20 through a first buffer spring 22, the swivel seat 5 can be buffered and shock-absorbing when the punching wheel assembly 12 and the guide column push the first pressing needle 8, thereby effectively avoiding the position offset between the swivel seat 5 and the rotating shaft 4 caused by the thrust when only the swivel seat 5 and the rotating shaft 4 are connected.

[0047] Preferably, the swivel seat 5 is connected to ejector pins 21 corresponding to the second pressing pins 9, and the ends of several ejector pins 21 respectively penetrate the corresponding second pressing pins 9. The ejector pins 21 are flush with the inner wall of the mold cavity 10 in the pressing state. When the second pressing pin 9 retracts after passing the second flush pressing seat 19, the ejector pins 21 are in the ejecting state to eject the blank.

[0048] Preferably, the pressure wheel assembly 13 includes a pressure seat 23 and a base 24 mounted on the outside of one end of the pressure seat 23. One end of the base 24 is connected to the second template 2, and the other end of the base 24 is connected to the pressure seat 23 through a second buffer spring 25. The second buffer spring 25 is passed between the base 24 and the pressure seat 23, so that the pressure wheel can buffer the pressure seat 23 when the second pressure needle 9 is subjected to pressure.
