A movable baffle assembly 20 disposed in the first mold cavity 11 and dividing the first mold cavity 11 into a second mold cavity 12 and a third mold cavity 13, wherein the movable baffle assembly 20 comprises a bottom baffle 21 with an accommodating groove 210 formed on the upper surface thereof and a sliding plate 22 with the bottom end disposed in the accommodating groove 210 and sliding up and down, and both ends of the bottom baffle 21 and the sliding plate 22 are disposed in the first clamping groove 14;

a punch 30 disposed directly above the die case 10 and matched with the cross section of the first die cavity 11;

Wherein the movable baffle assembly 20 is placed in the first die cavity 11, the refractory material can be placed in the first die cavity 11 or the second die cavity 12, the punch 30 is pressed downwards into the die cavity, a part of the sliding plate 22 pressed is slid into the accommodating groove 210, the movable baffle assembly 20 is removed, and the refractory material can be placed in the first die cavity 11 and pressed.

In this embodiment, the first clamping groove 14 is formed in the inner wall of the mold shell 10, the bottom end of the sliding plate 22 is placed in the accommodating groove 210 of the bottom baffle 21 to slide up and down, both ends of the bottom baffle 21 and the sliding plate 22 are placed in the clamping grooves, the first mold cavity 11 is divided into the second mold cavity 12 and the third mold cavity 13, the refractory raw material is placed in the first mold cavity 11 or the third mold cavity 13, the punching head 30 placed above the mold shell 10 is pressed down into the first mold cavity 11 to extrude the refractory raw material into a refractory brick shape, and in the extrusion process, the sliding plate 22 is gradually extruded into the accommodating groove 210 of the bottom baffle 21 under pressure until the refractory brick is extruded and molded, when refractory bricks applicable to the first mold cavity 11 are required to be produced, only the movable baffle assembly 20 is required to be taken out from the first mold cavity 11, when the mold size is adjusted, the punching head is not required to be replaced, and the operation is simple.

As an alternative embodiment, as shown in fig. 5, a first stopper 211 is provided on the top of the side wall of the accommodating groove 210 in an inward protruding manner, and a second stopper 220 is provided on the side walls of the two sides of the bottom end of the sliding plate 22 disposed in the accommodating groove 210 in an outward protruding manner, and the second stopper 220 is disposed below the first stopper 211. Thus, when the bottom of the sliding plate 22 slides up to the top of the accommodating groove 210 in the accommodating groove 210, the first stopper 211 and the second stopper 220 block each other, and the sliding plate 22 is not completely separated from the accommodating groove 210.

As an alternative embodiment, as shown in fig. 5, the flapper assembly 20 further includes a spring 23 vertically disposed in the receiving groove 210, wherein a bottom end of the spring 23 is fixed to a bottom of the receiving groove 210, and an upper end is fixed to the sliding plate 22. Thus, the spring 23 supports the bottom end of the sliding plate 22 to be placed at the bottom of the accommodating groove 210, and the part of the sliding plate 22 which is not placed in the accommodating groove 210 is all above the bottom baffle 21, and the bottom baffle 21 divides the first die cavity 11 into the second die cavity 12 and the third die cavity 13, when the punch 30 is pressed down into the first die cavity 11, the sliding plate 22 of the bottom baffle 21 is pressed to drive the spring 23 to shrink, a part of the sliding plate 22 slides into the accommodating groove 210, and when the punch 30 is returned to the upper side of the die shell 10, the sliding plate 22 is reset under the rebound effect of the spring 23.

As an alternative embodiment, as shown in fig. 2, when the movable shutter assembly 20 is placed in the first mold cavity 11, the springs 23 support the sliding plate 22, and the upper end of the sliding plate 22 is placed above the bottom shutter 21 and above the upper surface of the mold shell 10. Thus, as the punch 30 is pressed down into the first die cavity 11, the punch 30 is initially abutted against the top end of the slide plate 22 and then against the refractory material.

As an alternative embodiment, as shown in fig. 2, the stamping head 30 is disposed at a position just above the flapper assembly 20, and a second slot 31 is provided for matching the cross section of the sliding plate 22. Thus, when the punch 30 is pushed down into the first die cavity 11, the sliding plate 22 is clamped into the second clamping groove 31, so that deformation of the sliding plate 22 due to extrusion of the refractory raw material to two sides in repeated working engineering is avoided.

As an alternative embodiment, as shown in fig. 7 and 9, the device further includes a second clamping plate 32 detachably disposed in the second clamping groove 31, the second clamping groove 31 is concave toward two sides, the second clamping groove 31 is formed to have an inner portion wider than an opening of the second clamping groove 31, and the second clamping plate 32 is matched with the second clamping groove 31 in shape. Thus, when the refractory brick is produced by using the first mold cavity 11, the second clamping plate 32 is clamped into the second clamping groove 31, the second clamping groove 31 is filled, and the second clamping groove 31 is wider so that the second clamping plate 32 cannot fall off the second clamping groove 31.

As an alternative embodiment, as shown in fig. 6 and 8, the first card 15 is matched with the shape of the first card slot 14, and the first card 15 is detachably disposed in the first card slot 14. Thus, when the first mold cavity 11 is used for producing refractory bricks, the first clamping plate 15 is clamped into the first clamping groove 14, and the first clamping groove 14 is filled, so that the inner surface of the mold shell 10 is flat.

Preferably, as shown in fig. 4, two ends of the bottom baffle 21 form a clamping strip 212 matching the shape of the first clamping groove 14, so that when the two ends of the bottom baffle 21 are placed in the clamping groove, the fixing is stable.
