Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for producing the end of a high borosilicate glass tube with fine stripes on the inner wall. Background Technology

[0002] In the glass manufacturing industry, high borosilicate glass tubes with fine stripes on the inner wall are widely used in many industries such as chemical, medical, and optical due to their excellent heat resistance, chemical stability, and unique appearance. The production of the end parts of these glass tubes requires extremely high design and performance of the molds. The performance of a mold for producing the end parts of high borosilicate glass tubes directly affects the quality and production efficiency of the glass tube ends, which is related to the production cost and market competitiveness of enterprises. Therefore, the development of high-performance molds of this kind is of great significance.

[0003] Currently, in the production of fine-striped glass tube ends with high borosilicate inner walls, the existing technology typically uses molds composed of simple cavity structures. High-temperature high borosilicate molten glass is injected into the cavity and shaped by natural cooling or simple air cooling. This mechanical structure is relatively basic, and the technical principle is relatively simple. It aims to give the molten glass a specific shape through the mold cavity and then wait for the molten glass to gradually cool down and solidify under the action of the external environment.

[0004] However, this existing technology has significant problems. Due to the lack of precise control over the cooling process, relying solely on natural cooling or simple air cooling, the glass melt is prone to uneven temperature distribution during solidification. This leads to significant stress concentration inside the glass tube end, causing frequent defects such as cracks and deformations, seriously affecting product quality, increasing the defect rate, and consequently raising production costs. It cannot meet the market demand for high-quality high borosilicate glass tubes with fine inner stripes. Therefore, a mold for producing the end of high borosilicate glass tubes with fine inner stripes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mold for producing the end of a high borosilicate glass tube with fine stripes on the inner wall. It aims to improve the quality problems in the prior art, such as uneven temperature distribution at the end of the glass tube due to the lack of precise control of the cooling process, which leads to stress concentration, cracks and deformation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mold for producing the end of a high borosilicate glass tube with fine stripes on the inner wall includes a support base, an upper mold slidably connected inside the support base, a support plate fixedly connected to the top of the support base, a spring inside the support plate, one end of the spring fixedly connected to the inside of the support plate, and the other end fixedly connected to a lower mold, a quartz mold head fixedly connected to the top of the lower mold, and a cooling assembly inside the upper mold for quickly cooling and demolding the mold.

[0008] The cooling assembly includes a collection box, which is fixedly connected to the outer wall of the upper mold. A cooling fan is fixedly connected to one side of the collection box. A dual-head air pump is installed on the top of the collection box. The input end of the dual-head air pump is fixedly connected to the inside of the collection box. An output pipe is fixedly connected to the output end of the dual-head air pump. An annular pipe is fixedly connected to one end of the output pipe. A filter assembly is installed on the top of the collection box for filtering the coolant.

[0009] As a further description of the above technical solution:

[0010] The filter assembly includes a connecting collar, which is fixedly connected inside the collection box. A filter screen is fixedly connected to the inner wall of the connecting collar. A return pipe is fixedly connected inside the connecting collar, and one end of the return pipe is fixedly connected to the annular pipe. An installation component is provided inside the lower mold, which is used to assist the user in quickly installing the quartz mold head.

[0011] As a further description of the above technical solution:

[0012] The mounting assembly includes a fixing rod and a connecting shaft. The fixing rod is fixedly connected to the bottom of the quartz mold head, and the connecting shaft is fixedly connected inside the fixing rod.

[0013] As a further description of the above technical solution:

[0014] A sliding plate is slidably connected to the outer wall of the connecting shaft. A spring is provided at the bottom of the sliding plate. One end of the spring is fixedly connected to the inner wall of the fixed rod, and the other end is fixedly connected to the bottom of the sliding plate.

[0015] As a further description of the above technical solution:

[0016] The sliding plate is rotatably connected to a transmission rod, and the transmission rod is rotatably connected to a transmission plate on one side.

[0019] As a further description of the above technical solution:

[0020] The second sliding plate slides on the outer wall of the connecting shaft, and a third spring is provided on one side of the second sliding plate.

[0034] 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.

[0035] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a mold for producing the end of a high borosilicate glass tube with fine stripes on the inner wall, comprising a support base 1, which supports the structure of the entire mold. An upper mold 2 is slidably connected inside the support base 1, and a support plate 3 is fixedly connected to the top of the support base 1. A spring 4 is provided inside the support plate 3 to provide a certain reaction force when the mold is working. One end of the spring 4 is fixedly connected inside the support plate 3, and the other end is fixedly connected to a lower mold 5. A quartz mold head 6 is fixedly connected to the top of the lower mold 5 to form the end of the glass tube. A cooling component is provided inside the upper mold 2 to quickly cool and demold the mold.

[0036] The cooling assembly includes a collection tank 7 for storing coolant. The collection tank 7 is fixedly connected to the outer wall of the upper mold 2. A cooling fan 8 is fixedly connected to one side of the collection tank 7 for cooling the coolant. A dual-head air pump 9 is installed on the top of the collection tank 7 for delivering coolant and ensuring its flow. The input end of the dual-head air pump 9 is fixedly connected inside the collection tank 7, and the output end of the dual-head air pump 9 is fixedly connected to an output pipe 10. One end of the output pipe 10 is fixedly connected to an annular pipe 11. A filter assembly is installed on the top of the collection tank 7 for filtering the coolant. The filter assembly includes a connecting collar 13, which is fixedly connected inside the collection tank 7. A filter screen 14 is fixedly connected to the inner wall of the connecting collar 13 for filtering the coolant and ensuring flow stability. A return pipe 12 is fixedly connected inside the connecting collar 13, and one end of the return pipe 12 is fixedly connected to the annular pipe 11. An installation assembly is installed inside the lower mold 5 to assist the user in quickly installing the quartz mold head 6.

[0037] Specifically, when producing the ends of high borosilicate glass tubes with fine inner stripes, it is necessary to avoid uneven temperature distribution of the molten glass due to slow cooling, which could lead to internal stress concentration, surface defects, and long forming cycles. Through the cooperation of the upper mold 2 and the quartz mold head 6, the mold can be quickly stamped. During the stamping process, the coolant inside the collection box 7 is extracted using the input end of the dual-head air pump 9 and introduced into the annular pipe 11 through the output pipe 10. The coolant flows within the annular pipe 11, absorbing the heat generated during the stamping process, thus aiding in mold forming and demolding. During the coolant flow, the coolant is further guided into the connecting collar 13 by the return pipe 12. Inside the connecting collar 13, the coolant is filtered through the filter screen 14 to remove impurities, ensuring the cleanliness of the coolant. The filtered coolant is returned to the collection box 7 to maintain stable circulation of the cooling components. To ensure cooling effect, a cooling fan 8 fixedly connected to the outer wall of the collection box 7 quickly cools the coolant, thereby improving cooling performance and ensuring rapid mold cooling.

[0038] Reference Figure 4 - Figure 6 The mounting assembly includes a fixed rod 15 and a connecting shaft 16. The fixed rod 15 is fixedly connected to the bottom of the quartz mold head 6 to provide a stable connection and support. The connecting shaft 16 is fixedly connected inside the fixed rod 15. A sliding plate 17 is slidably connected to the outer wall of the connecting shaft 16. A spring 18 is provided at the bottom of the sliding plate 17 to provide a certain elastic support and ensure the stable movement of the assembly. One end of the spring 18 is fixedly connected to the inner wall of the fixed rod 15, and the other end is fixedly connected to the bottom of the sliding plate 17. A transmission rod 19 is rotatably connected inside the sliding plate 17 to further transmit power and drive the movement of subsequent components. A transmission plate 20 is rotatably connected to one side of the transmission rod 19.

[0039] Specifically, when the mold needs regular inspection and maintenance to ensure product quality, the operator can directly pull the quartz mold head 6. Under the action of the pulling force, the locking block 24 will slide in the groove inside the lower mold 5, generating a certain squeezing force. Under the action of the squeezing force, the locking block 24 will retract into the fixed rod 15, driving the transmission plate 20 to move synchronously. The movement of the transmission plate 20 will cause the transmission rod 19 and transmission rod 21 to deflect synchronously, thereby driving the sliding plate 17 and sliding plate 22 to slide along the outer wall of the connecting shaft 16.

[0040] Reference Figure 4 - Figure 6 The transmission plate 20 is rotatably connected to the transmission rod 21. The transmission rod 21 is rotatably connected to the sliding plate 22 on one side, which is used to compress the spring 3 23 and make it elastically deform. The sliding plate 22 slides on the outer wall of the connecting shaft 16. The spring 3 23 is provided on one side of the sliding plate 22, which is also used to provide elastic restoring force to ensure that the equipment can return to its original state. One end of the spring 3 23 is fixedly connected to the outer wall of the connecting shaft 16, and the other end is fixedly connected to the top of the sliding plate 22. The transmission plate 20 is fixedly connected to the blocking block 24 on one side.

[0041] Specifically, the sliding of sliding plate 17 and sliding plate 22 will compress spring 2 18 and spring 3 23, causing them to undergo elastic deformation simultaneously and store elastic potential energy. This elastic potential energy provides elastic restoring force for subsequent installation, helping operators to quickly complete the inspection and installation of the stamping die, thereby ensuring the processing stability of the die, improving operating efficiency and maintenance convenience, and ensuring the efficient operation of the equipment and the long-term stability of the die.

[0042] Working Principle: When using this device, the upper mold 2 and the quartz mold head 6 work together to quickly stamp the mold. During the stamping process, the coolant inside the collection tank 7 is drawn out through the input end of the dual-head air pump 9 and introduced into the annular pipe 11 through the output pipe 10. The coolant absorbs the heat generated during the stamping process by flowing inside the annular pipe 11, assisting in the molding and demolding of the mold. During the cooling flow, the coolant is further guided into the connecting collar 13 by the return pipe 12. The coolant is filtered by the filter screen 14 inside the connecting collar 13. After filtration, the coolant returns to the collection tank 7 and is rapidly cooled by the cooling fan 8 fixed to the outer wall of the collection tank 7, ensuring the cooling performance. When it is necessary to inspect or maintain the mold, the coolant is then... The operator directly pulls the quartz mold head 6. Under the pulling force, the locking block 24 slides in the internal groove of the lower mold 5, thereby generating a squeezing force. Under the squeezing force, the locking block 24 retracts into the fixed rod 15, driving the transmission plate 20 to move synchronously. The movement of the transmission plate 20 causes the transmission rod 19 and transmission rod 21 to deflect synchronously, further driving the sliding plate 17 and sliding plate 22 to slide along the outer wall of the connecting shaft 16. The sliding compression of the sliding plate 17 and sliding plate 22 compresses the spring 28 and spring 3, causing the spring 28 and spring 3 to undergo elastic deformation simultaneously, storing elastic potential energy. This provides a certain elastic restoring force for subsequent installation, thus facilitating the operator to quickly inspect and install the stamping mold and ensuring the stability of the processing.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
