Description

Technical Field

[0001] This invention relates to the field of glass container forming molds, and in particular to an air blowing assembly for glass container forming molds. Background Technology

[0002] To achieve the final shaping of glass containers, air can be blown into the molten glass blank through an air blowing head. The airflow is then used to cooperate with the cavity of the forming mold to shape the glass container.

[0003] The molten glass billet has a high initial temperature. Existing air blowing heads, where the airflow is directly delivered to the forming mold, struggle to dissipate heat, resulting in poor heat dissipation and hindering continuous operation. While separating the airflow for heat dissipation from the blowing head could be implemented, it wouldn't guarantee sufficient airflow during the glass container forming process, necessitating improvements. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide an air blowing component for glass container molding molds, which improves heat dissipation and ensures the amount of air blown during the glass container molding process.

[0005] To solve the above-mentioned technical problems, the present invention provides a blowing assembly for a glass container forming mold, comprising: a blowing head, a straight tube, a positioning seat, a guide sleeve, a spring, and a floating sleeve. The guide sleeve is disposed on the positioning seat, the blowing head is disposed on the guide sleeve, and a guide hole is recessed at the bottom of the blowing head. An annular flange extending into the guide hole is disposed at the top of the guide sleeve. The floating sleeve extends from below the positioning seat through the annular flange and into the guide hole. An annular piece is disposed at the top of the floating sleeve above the annular flange, and the spring is disposed above the annular piece. The straight tube is disposed in the blowing head and extends downward into the floating sleeve. A downward-extending insertion hole corresponding to the straight tube is disposed at the top of the floating sleeve. A cover plate is disposed at the bottom of the floating sleeve, and a blowing hole extending downward to the bottom surface of the cover plate is disposed at the bottom of the insertion hole.

[0006] In a preferred embodiment of the present invention, an exhaust hole extending obliquely upward to the outside of the floating sleeve is provided on the inner wall of the insertion hole, and a through hole located outside the end of the exhaust hole is provided in the positioning seat, and the diameter of the insertion hole is larger than the outer diameter of the straight pipe.

[0007] In a preferred embodiment of the present invention, the air blowing head is provided with a first screw that is connected to the guide sleeve.

[0008] In a preferred embodiment of the present invention, the positioning seat is provided with fixing ears located on both sides of the guide sleeve, the fixing ears are provided with second screws connected to the guide sleeve, and the positioning seat is provided with spaced pads located below the guide sleeve.

[0009] In a preferred embodiment of the present invention, the outer diameter of the ring plate is larger than the inner diameter of the annular flange, a third screw connected to the floating sleeve is provided on the ring plate, the spring is sleeved on the straight tube, and a positioning ring extending into the spring is provided in the middle of the ring plate.

[0010] In a preferred embodiment of the present invention, a guide groove is vertically provided on the side of the floating sleeve, and a fourth screw extending into the guide groove is provided on the side of the air blowing head.

[0011] In a preferred embodiment of the present invention, the bottom of the positioning seat is symmetrically provided with guide pins located on both sides of the floating sleeve and extending downward.

[0012] In a preferred embodiment of the present invention, a retaining ring is provided at the top of the guide pin, a stud is provided on the retaining ring to extend upward through the positioning seat, and a nut is provided on the stud located above the positioning seat.

[0013] In a preferred embodiment of the present invention, the bottom of the cover plate is recessed and provided with a first exhaust groove extending from the bottom of the air hole to the edge of the cover plate.

[0014] In a preferred embodiment of the present invention, a second exhaust groove connected to the first exhaust groove is vertically provided on the edge of the cover plate.

[0015] The beneficial effects of this invention are as follows: In the air-blowing assembly for a glass container forming mold, before the cover plate contacts the forming mold, the floating sleeve is kept in a low position under the action of a spring. Part of the airflow from the straight pipe into the insertion hole is discharged downwards through the air-blowing hole to cool the cover plate, and the other part is discharged through the exhaust hole to cool the floating sleeve and positioning seat, thus improving the working stability of the cover plate, floating sleeve, and positioning seat. After the cover plate contacts the forming mold, it is pressed and drives the floating sleeve to move upwards. The airflow from the straight pipe is directly discharged downwards through the air-blowing hole and sent into the forming mold for air-blowing forming of the glass container, ensuring the air volume. Excess air in the glass container is discharged with the first exhaust groove, which can both accelerate the cooling and solidification of the glass container after forming and improve the cooling effect of the cover plate, achieving two benefits in one.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-3 The embodiments of the present invention include:

[0022] like Figures 1-3 The air blowing assembly for the glass container forming mold shown includes: an air blowing head 2, a straight tube 4, a positioning seat 1, a guide sleeve 6, a spring 16, and a floating sleeve 19. The guide sleeve 6 is mounted on the positioning seat 1. In this embodiment, the positioning seat 1 is provided with fixing ears 8 on both sides of the guide sleeve 6, and the fixing ears 8 are provided with second screws 7 that connect to the guide sleeve 6, facilitating assembly. Spacers 26 are spaced apart on the positioning seat 1 below the guide sleeve 6, leaving a gap between the guide sleeve 6 and the positioning seat 1, reducing the transfer of heat from the positioning seat 1 to the guide sleeve 6, and improving ventilation and heat dissipation.

[0023] The air blowing head 2 is mounted on the guide sleeve 6. A guide hole is recessed at the bottom of the air blowing head 2, and an annular flange 18 extending into the guide hole is provided at the top of the guide sleeve 6, ensuring precise assembly. In this embodiment, as shown... Figure 1 As shown, the air blowing head 2 is provided with a first screw 5 that connects to the guide sleeve 6, which improves the structural stability and avoids the problem of the guide sleeve 6 falling off.

[0024] The floating sleeve 19 extends from below the positioning seat 1 through the annular flange 18 and into the guide hole. A ring plate 17 is located on the top of the floating sleeve 19, above the annular flange 18. In this embodiment, the outer diameter of the ring plate 17 is larger than the inner diameter of the annular flange 18. A third screw connected to the floating sleeve 19 is provided on the ring plate 17. The ring plate 17 limits the downward movement of the floating sleeve 19, preventing it from falling off. Furthermore, as... Figure 3 As shown, the floating sleeve 19 has a guide groove 14 vertically arranged on its side, and the air blowing head 2 has a fourth screw 3 extending into the guide groove 14 on its side, to prevent the floating sleeve 19 from twisting and improve the straightness of the floating.

[0025] The spring 16 is positioned above the ring plate 17 to provide elastic downward pressure on the ring plate 17, which facilitates the downward repositioning of the floating sleeve 19 after it floats up. The straight tube 4 is disposed in the air blowing head 2 and extends downward into the floating sleeve 19. The top of the floating sleeve 19 is provided with a downward-extending insertion hole 21 corresponding to the straight tube 4. In this embodiment, the diameter of the insertion hole 21 is larger than the outer diameter of the straight tube 4, so as not to affect the up-and-down floating of the floating sleeve 19.

[0026] like Figure 3 As shown, spring 16 is sleeved on straight tube 4, and a positioning ring 15 extending into spring 16 is provided in the middle of ring plate 17, which improves the stability of spring 16. A cover plate 20 is provided at the bottom of floating sleeve 19, and an air blowing hole 22 extending downward to the bottom surface of cover plate 20 is provided at the bottom of insertion hole 21. An air supply pipe is connected to the top of straight tube 4, and air is fed into insertion hole 21 and air blowing hole 22 through straight tube 4. Air blowing hole 22 facilitates the downward discharge of airflow and delivery into molding die.

[0027] like Figure 1 and Figure 3 As shown, guide pins 10 are symmetrically arranged on both sides of the floating sleeve 19 and extend downward at the bottom of the positioning seat 1. The guide pins 10 can cooperate with the pin holes on the mold to guide the positioning seat 1 when it moves downward. A retaining ring 11 is provided on the top of the guide pin 10. A stud 13 is provided on the retaining ring 11 and extends upward through the positioning seat 1. A nut 12 is provided on the stud 13 and located above the positioning seat 1 to fix the guide pin 10. This makes disassembly and assembly convenient.

[0028] An exhaust hole 23 extending obliquely upward to the outside of the floating sleeve 19 is provided on the inner wall of the insertion hole 21. A through hole 25 located on the outside of the end of the exhaust hole 23 is provided in the positioning seat 1, which is conducive to the outward exhaust of the exhaust hole 23. Before the cover plate 20 moves down and contacts the forming mold, the floating sleeve 19 is kept in a low position under the action of the spring 16. Part of the airflow sent downward into the insertion hole 21 by the straight pipe 4 is discharged downward through the air blowing hole 22 to cool the cover plate 20, and the other part is discharged through the exhaust hole 23 to cool the floating sleeve 19 and the positioning seat 1, thereby improving the working stability of the cover plate 20, the floating sleeve 19 and the positioning seat 1.

[0029] In this embodiment, the bottom of the cover plate 20 is recessed and has a first exhaust groove 24 extending from the bottom of the air blowing hole 22 to the edge of the cover plate 20. The edge of the cover plate 20 is vertically provided with a second exhaust groove 9 connected to the first exhaust groove 24, which improves the exhaust effect. After the cover plate 20 contacts the molding die, it is pressed and drives the floating sleeve 19 to move upward. The airflow of the straight pipe 4 is directly discharged downward through the air blowing hole 22 and sent into the molding die for blowing and forming of the glass container. This ensures the amount of air blown. The excess air in the glass container is discharged in turn with the first exhaust groove 24 and the second exhaust groove 9, which can accelerate the cooling and solidification of the glass container after molding and improve the cooling effect of the cover plate 20, achieving two benefits at once.

[0030] In summary, the air blowing assembly for glass container molding dies disclosed in this invention ensures the air blowing volume during glass container molding, enhances the air cooling effect of the assembly, and improves the stability of continuous operation in high-temperature environments.

[0031] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
