[0024] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0025] Embodiment 1

[0026] In a typical embodiment of the present application, a glass forming tool is provided, such as Figure 1-3 As shown, it includes a support platform 1 and a forming mold 2, the forming mold 2 includes a lower mold 5 arranged on the support platform and an upper mold 6 molded with the lower mold, the support platform is tilted, and the support platform can be set to a specific tilt angle as needed by fixing the adjustment screw 10. The support platform is set on a horizontal platform 9, and can also be placed on the ground or other working platforms as needed.

[0027] like Figure 1-2 As shown, the lower mold 6 and the upper mold 5 are respectively provided with a lower mold molding surface 51 and a lower mold molding surface 61, and the lower mold molding surface and the lower mold molding surface are connected to form a casting cavity 7 that is closed up and down. In this embodiment, in order to process and shape the glass rod, the cross section of the casting cavity is circular, and half of the casting cavity 7 is distributed in the inner cavity of the upper mold and the other half is distributed in the inner cavity of the lower mold, which can ensure the accuracy of the processed shape. In the length direction, one end of the casting cavity is a pouring port 8, and the other end is closed.

[0028] like Figure 1 As shown, the lower mold 5 arranged on the support platform is tilted synchronously with the support platform 1, and a rear stop 52 is fixedly arranged at the lower end of the lower mold 5. When the mold is closed, the rear stop 52 abuts against the upper mold 6, thereby closing the lower end of the casting cavity to ensure the precise molding of the functional glass. The rear stop is made of the same material as the lower mold, and can be processed integrally with the lower mold, or assembled by welding or other methods.

[0029] In addition, in order to further ensure the accuracy of glass casting, Figure 1 As shown, a longitudinally protruding positioning pin 53 is provided on the end surface of the lower mold that is connected to the upper mold, and a corresponding positioning pin hole 62 is longitudinally provided on the connecting end surface of the upper mold. When the upper mold 6 and the lower mold 5 are molded together, the positioning pin 53 and the positioning pin hole 62 are locked together to ensure that the upper mold and the lower mold are tightly sealed and the shape accuracy is ensured. At the same time, the molding mold is prevented from shifting up and down during the casting process, thereby improving the processing accuracy. Preferably, multiple positioning pins and positioning pin holes can be provided around the cavity.

[0030] like Figure 2-3 As shown, the lower mold 5 is processed to be longer than the upper mold 6, so when the molding mold is closed, the lower end of the upper mold and the lower mold are abutted by the back stop, and the higher end of the lower mold 5 forms an open pouring port 8 for easy pouring.

[0031] like Figure 1-3 As shown, a lifting eye 63 is provided on the top of the upper mold 6 away from the butt joint surface, which is convenient for lifting the upper mold to separate the molds, thereby taking out the molded glass for subsequent processing. The lifting eye is made of steel and can be fixed to the top of the upper mold by welding or other methods. In order to ensure the stability and safety of the upper mold during lifting, at least two lifting eye holes are provided.

[0032] In addition, in order to improve the processing efficiency, a plurality of workstations are arranged on the support table 1, which are divided into a processing position 3 and a placement position 4. Figure 1 As shown, the lower mold 5 is placed on the processing position 3 and supported by the inclined support platform. Before pouring, the upper mold and the lower mold are placed in the muffle furnace to be preheated to a specific temperature, so that the upper mold molding surface and the lower mold molding surface are heated, and then placed on the processing position for mold closing and pouring. The placement position 4 is arranged in parallel with the processing position 3, and is used to place the separated upper mold 6 after the glass is processed and formed, so as to facilitate the removal of the formed glass. Multiple processing positions can be set in parallel to facilitate simultaneous pouring or sequential pouring to improve processing efficiency.

[0033] The lower mold and upper mold are made of ductile iron with low thermal conductivity, thus good thermal insulation performance and slow heat dissipation. They can maintain a specific temperature after heating, avoiding vacuum bubbles or mold sticking due to rapid temperature changes during the casting process of functional glass, thereby ensuring the quality of glass molding.

[0034] The support platform 1 is made of carbon steel to ensure that it can bear weight and is not easily deformed.

[0035] In addition, the support platform in this embodiment adopts a forward and backward moving structure, and the bottom of the support platform 1 is fastened to the horizontal platform 9 by adjusting screws 10 to achieve adjustable inclination angle, which can match the flow rate of glass liquids with different viscosities, so that the material liquid can be uniformly injected into the mold at a certain speed during the pouring process, and has better adaptability. Figure 1 As shown, the forward and backward moving structure means that the lower ends of the two side legs of the support platform can move in the direction of the vertical line connecting the two legs on the horizontal plane, that is, move forward and backward, and the upper part of the legs is always in contact with the support plate of the support platform. When the inclination angle of the support platform needs to be increased, adjust the bottom ends of the two side legs to move outward a certain distance synchronously, and then tighten the adjustment screw 10 to ensure that the support platform is fastened in this position. When the inclination angle of the support platform needs to be reduced, loosen the adjustment screw 10, then adjust the two side legs to retreat inward a certain distance, and then tighten the adjustment screw 10.

[0036] The utility model adopts an upper and lower separation structure, has both heat preservation and heat dissipation properties, is fast in molding, does not stick to the mold, has high molding precision, can be poured multiple times, can be used repeatedly, is easy to clean, and is convenient for cleaning residual glass debris.

[0037] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
