[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides a quartz crucible forming device, comprising: a mold mechanism 1, comprising a lower mold assembly 11, an upper mold assembly 12 slidably embedded on the lower mold assembly 11; a cylinder mechanism 2 fixedly mounted on the lower mold assembly 11, the cylinder mechanism 2 can drive the upper mold assembly 12 to move up and down; a quick demolding mechanism 3, comprising an ejector assembly 31 arranged inside the lower mold assembly 11, an air intake pipe 32 opened on the lower mold assembly 11, the air intake pipe 32 connects the bottom of the ejector assembly 31 and the outside of the lower mold assembly 11 to each other;

[0022] Among them, quartz powder is placed in the lower mold assembly 11, and the upper mold assembly 12 can be moved downward and embedded in the lower mold assembly 11 by controlling the cylinder mechanism 2 to work. The quartz raw material can be squeezed into the shape of a crucible by extrusion. The gas is introduced into the air inlet pipe 32 to lift up the ejection assembly 31. The ejection assembly 31 is lifted up, and the molding crucible is pushed up, so that it is convenient for the staff to take out the molding crucible and carry out the next step of processing.

[0023] Specifically, the lower mold assembly 11 includes a lower mold body 111 , a group of crucible grooves 112 are opened inside the lower mold body 111 , and a group of guide rods 113 are fixedly connected to the upper end of the lower mold body 111 .

[0024] Specifically, the upper mold assembly 12 includes a pressing plate 121 , a group of upper mold bodies 122 are fixedly connected to the bottom of the pressing plate 121 , and a U-shaped bracket 123 is also fixedly connected to the upper end of the pressing plate 121 .

[0025] Specifically, the cylinder mechanism 2 includes a cylinder barrel 21, the upper end of the cylinder barrel 21 is fixedly connected to a cylinder rod 22, the upper end of the outer side of the cylinder barrel 21 is fixedly connected to a limit ring 1 23, the outer side of the cylinder rod 22 is fixedly connected to a limit ring 24 near the upper end, and the top end of the outer side of the cylinder rod 22 is also rotatably connected to a threaded ring 25.

[0026] Specifically, the pressing plate 121 is slidably embedded in the guide rod 113 , the cylinder barrel 21 is embedded in the lower mold body 111 , and the U-shaped bracket 123 is limitedly embedded in the cylinder rod 22 through the threaded ring 25 .

[0027] As can be seen from the above, controlling the operation of the cylinder mechanism 2 can enable the cylinder rod 22 to drive the U-shaped bracket 123 to move through the limit ring 24 and the threaded ring 25. The movement of the U-shaped bracket 123 will cause the pressure plate 121 to drive a group of upper mold bodies 122 to move up and down. The downward movement of a group of upper mold bodies 122 will cause the quartz powder placed in a group of crucible grooves 112 to be squeezed into a crucible shape, and a group of guide rods 113 can play a guiding role.

[0028] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a limiting slot 114 is further provided inside the lower mold body 111; the ejection assembly 31 includes a ejector column 311, and the lower end of the outer side of the ejector column 311 is also fixedly connected to a limiting ring 312; the ejector column 311 is movably embedded in the limiting slot 114 through the limiting ring 312, and the air intake pipe 32 connects the bottom of the ejector column 311 and the outside of the lower mold body 111 to each other.

[0029] As can be seen from the above, when gas is introduced into the gas inlet pipe 32 , the gas will drive the top column 311 to move upward, and the upward movement of the top column 311 will lift up the formed crucible, thereby facilitating the staff to take the crucible out of a group of crucible slots 112 .
