Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical glass processing technology, specifically a structure for automatically aligning raw materials during the optical glass forming process. Background Technology
[0002] Optical glass is an amorphous (glassy) optical medium that transmits light. It can be used to make various optical elements such as prisms, lenses, and filters, altering the direction, phase, and intensity of light after it passes through. Based on different requirements, optical glass can be divided into three main categories: ① Colorless optical glass – almost completely transparent across a wide visible and near-infrared wavelength range, it is the most widely used type of optical glass. There are hundreds of grades based on refractive index and dispersion, which can be divided into two types: crown glass (represented by K) and flint glass (represented by F). Crown glass is borosilicate glass; adding alumina creates flint glass. The main difference is that flint glass has a higher refractive index and dispersion, making it more commonly used in spectral elements. ② Radiation-resistant optical glass – possessing all the properties of colorless optical glass and exhibiting minimal performance changes under radioactive irradiation. Used in optical instruments exposed to gamma radiation, its types and grades are the same as colorless optical glass. Its chemical composition is based on colorless optical glass, with the addition of a small amount of cerium dioxide to eliminate color centers formed by high-energy radiation in the glass, making the light absorption of this glass change very little after irradiation. ③ Colored optical glass—has specific absorption or transmission properties for certain wavelengths of light. Also known as filter glass, there are over a hundred varieties. Color filters selectively absorb certain colors, while neutral density filters absorb all wavelengths of light equally, only reducing the intensity of the beam without changing its color. Interference filters, based on the principle of light interference, reflect unwanted colors instead of absorbing them. Optical glass has high transparency, high chemical and physical (structural and performance) homogeneity, and specific and precise optical constants. It can be divided into silicate, borate, phosphate, fluoride, and chalcogenide series.
[0003] Currently, optical glass raw materials are heated and molded into the required shape. However, because the raw materials are softened after heating, they cannot be aligned properly when placed in the lower mold. The mold is heavy, and manual shaking is labor-intensive. At the same time, the high temperature can easily cause burns. The only way to improve the product qualification rate is to rely on the experience of the operators. Utility Model Content
[0004] The purpose of this invention is to overcome the problems mentioned in the background art and provide a structure that enables automatic alignment of raw materials in the optical glass forming process. This structure uses mechanical shaking to automatically align the raw materials in the lower mold, and the product quality is guaranteed after the upper mold is closed, thereby improving production efficiency.
[0005] The objective of this utility model is mainly achieved through the following technical solutions:
[0006] The optical glass forming process utilizes a structure for automatic raw material alignment, comprising two sets of parallel support bases. A horizontal moving mechanism and a support frame are mounted on the top of each support base. A lower mold is positioned between the horizontal moving mechanisms and connected to them, allowing for horizontal reciprocating motion as the mechanisms move. A rotating mechanism is connected to the end of the lower mold, enabling it to rotate. A support plate is positioned between the support frames and fixed to them. A vertical drive mechanism is mounted on the support plate, with an upper mold mounted at its bottom. Driven by the vertical drive mechanism, the upper mold can move vertically, approaching or moving away from the lower mold. Currently, optical glass production involves pressing raw materials into the desired shape using molds. However, because the raw materials soften after heating, their free fall into the lower mold can cause them to fail to reach the bottom or shift due to collisions and friction with the mold's inner wall. The heavy weight of the mold makes manual shaking labor-intensive, and improper force can cause it to tip over, resulting in burns. This method relies heavily on operator experience, leading to a low product yield. To address the aforementioned issues, this solution designs a structure for automatic raw material alignment during the optical glass forming process. Two sets of parallel support bases are used as supports. A horizontal moving mechanism and a support frame are installed on the top of each support base. A lower mold is positioned between the horizontal moving mechanisms and is connected to them. When the horizontal moving mechanisms move, the lower mold can perform horizontal reciprocating motion. This reciprocating motion, driven by the horizontal moving mechanisms, causes the lower mold to vibrate, allowing the raw material in the lower mold to fall to the bottom as much as possible. A support plate is positioned between the support frames and is fixed to them. A vertical drive mechanism is installed on the support plate, and an upper mold is installed at the bottom of the vertical drive mechanism. Driven by the vertical drive mechanism, the upper mold can move vertically, moving closer to or away from the lower mold, thus forming a mold closing or opening mechanism. Then, a rotating mechanism connected to the end of the lower mold drives the lower mold to rotate, unloading the formed product from the lower mold. The entire process requires no manual contact, preventing burns from high temperatures. Furthermore, the automatic alignment of the raw material improves the forming quality.
[0007] Furthermore, the horizontal movement mechanism includes a guide rail, which is fixed to the top surface of the support base. A guide block is disposed above the guide rail, and the bottom of the guide block is recessed to form a guide groove. The guide rail is inserted into the guide groove, and the guide block can reciprocate along the guide rail. The guide rail protrudes and is fixed to the top surface of the support base, serving as a guide during horizontal movement. Through the engagement of the guide block and the guide rail, the guide block can reciprocate along the guide rail.
[0008] Furthermore, a mounting block is fixed above the guide block, and the end of the lower mold is connected to the mounting block. The rotating mechanism is fixed on the mounting block. The output shaft of the rotating mechanism passes through the mounting block and is connected to the end of the lower mold. In this way, the rotating mechanism can drive the lower mold to rotate through the output shaft, thus pouring the formed product out of the lower mold.
[0009] Furthermore, the support base is equipped with a main power mechanism, which is connected to the mounting block and can drive the mounting block to reciprocate. The main power mechanism uses a cylinder, which drives the mounting block to reciprocate, which in turn drives the lower mold to reciprocate. Through rapid reciprocating movement, the lower mold vibrates, thereby dropping the raw material in the lower mold into the appropriate position. This achieves automatic alignment before the upper mold moves down, resulting in higher quality products.
[0010] Furthermore, the support base is equipped with a limiting platform and a baffle. The guide rail and guide block are both located between the limiting platform and the baffle. A guide shaft is provided between the limiting platform and the baffle, and the guide shaft passes through the guide block and its two ends are connected to the limiting platform and the baffle respectively. In order to prevent the guide block from deviating from its trajectory during reciprocating movement, the movement is limited by the guide shaft. The two guide shafts ensure that the movement trajectory is unique, and the limiting platform and the baffle can also prevent the guide block from suddenly flying out and causing damage.
[0011] In summary, this utility model has the following advantages compared with the prior art: This solution uses a horizontal moving mechanism to drive reciprocating motion, which causes the lower mold to vibrate. This allows the raw materials in the lower mold to fall to the bottom as much as possible. The rotating mechanism connected to the end of the lower mold can drive the lower mold to rotate, and pour the formed product out of the lower mold. The whole process does not require manual touch, which prevents high temperature burns. At the same time, the automatic alignment of raw materials can improve the molding quality.

[0019] like Figure 1 As shown, the optical glass forming process of this embodiment realizes the structure of automatic alignment of raw materials, including two sets of parallel support seats 1. The support seats 1 are used as the main support structure. A horizontal moving mechanism is installed on the top of the support seats 1. A lower mold 8 is arranged between the horizontal moving mechanisms and is connected to the horizontal moving mechanism. When the horizontal moving mechanism moves, the lower mold 8 can perform horizontal reciprocating motion. The reciprocating motion driven by the horizontal moving mechanism causes the lower mold 8 to vibrate, so that the raw materials in the lower mold 8 can fall to the bottom as much as possible.
[0020] A support frame is installed on the top of the support base 1. The support frame includes a vertical rod 2 and a horizontal rod 3. The bottom of the vertical rod 2 is fixed vertically to the top of the support base 1, and the top of the vertical rod 2 is fixed to the outer wall of the horizontal rod 3. A support plate 6 is provided between the horizontal rods 3. The support plate 6 is also fixed to the horizontal rods 3. A vertical drive mechanism 7 is provided on the support plate 6. An upper mold 4 is installed at the bottom of the vertical drive mechanism 7. The vertical drive mechanism 7 uses a cylinder as a power mechanism. One end of the piston rod 5 is located in the cylinder, and the other end is connected to the upper mold 4. The upper mold 4 can move vertically under the drive of the piston rod 5 and move closer to or away from the lower mold 8 to form a mold closing or opening. Then, through the rotation mechanism connected to the end of the lower mold 8, the rotation mechanism can drive the lower mold 8 to rotate and pour the formed product out of the lower mold. The whole process does not require manual touch to prevent high temperature burns. At the same time, the automatic alignment of raw materials can improve the molding quality.
[0021] The horizontal movement mechanism includes a guide rail 11, which is fixed to the top surface of the support base 1. A guide block 12 is disposed above the guide rail 11, with a guide groove formed by the concave bottom of the guide block 12. The guide rail 11 is inserted into the guide groove, and the guide block 12 can reciprocate along the guide rail 11. The guide rail 11 protrudes and is fixed to the top surface of the support base 1, serving as a guide during horizontal movement. Through the engagement of the guide block 12 and the guide rail 11, the guide block 12 can reciprocate along the guide rail.
[0022] A mounting block 9 is fixed above the guide block 12. The end of the lower mold 8 is connected to the mounting block 9, and the rotating mechanism 13 is fixed on the mounting block 9. The output shaft of the rotating mechanism 13 passes through the mounting block 9 and is connected to the end of the lower mold 8. In this way, the rotating mechanism 13 can drive the lower mold 8 to rotate through the output shaft, so that the formed product can be poured out of the lower mold 8.
[0023] The support base 1 is equipped with a main drive mechanism 17, which is connected to the mounting block 9 and can drive the mounting block 9 to reciprocate. The main drive mechanism is a cylinder, which is connected to a piston rod 14. The piston rod 14 is connected to the mounting block 9. The piston rod 14 quickly extends and retracts, driving the mounting block 9 to reciprocate, which in turn drives the lower mold 8 to reciprocate. Through rapid reciprocating movement, the lower mold 8 is vibrated, thereby dropping the raw material in the lower mold 8 into the appropriate position. In this way, automatic alignment is achieved before the upper mold moves down, resulting in higher quality products.
[0024] To prevent the guide block 12 from suddenly flying out and causing damage, a limiting platform 16 and a baffle 10 are provided on the support base 1. The guide rail 11 and the guide block 12 are both located between the limiting platform 16 and the baffle 10. At the same time, to prevent the guide block 12 from deviating from the trajectory when it moves back and forth, two guide shafts 15 are provided between the limiting platform 16 and the baffle 10. After passing through the guide block 12, the two ends of the guide shafts 15 are connected to the limiting platform 16 and the baffle 10 respectively. The movement is limited by setting the guide shafts 15, and the two guide shafts 15 make the movement trajectory unique.
[0025] This solution uses vibration to align the raw material in the mold, achieving automatic alignment before the upper mold moves down, ensuring accurate positioning and higher quality of the molded product.
