[0028] In one embodiment, the connection assembly 3 includes a T-shaped connection block 301 , and an offset groove 302 is formed at one end of the T-shaped connection block 301 .

[0029] Specifically: when the T-shaped connecting block 301 extends into the insertion groove 105, it squeezes the baffle 202, and the baffle 202 squeezes the spring 203 to one side and moves. At this time, the connecting rod 201 and the limit block 204 enter the offset groove 302. The offset groove 302 is provided to avoid the obstruction of the connecting rod 201 and the limit block 204 when the T-shaped connecting block 301 extends into the insertion groove 105.

[0030] In one embodiment, one end of the four connecting rods 201 is fixedly connected to one side of the inner cavity of the four extending grooves 105, one end of the four springs 203 is fixedly connected to one side of the inner cavity of the four extending grooves 105, the surfaces of the four baffles 202 are movably embedded in the four extending grooves 105, the surfaces of one end of the four baffles 202 are movably embedded in the four movable grooves 107, and the surfaces of the other end of the four baffles 202 are movably embedded in the four push baffle grooves 108.

[0031] Specifically, the baffle 202 is movably embedded in the movable groove 107 to provide a direction for the movement of the baffle 202, so as to facilitate the control of the moving direction of the baffle 202 under the extrusion of the T-shaped connecting block 301. At the same time, the movable groove 107 provides a movable space for one end of the baffle 202.

[0032] In one embodiment, one end of the four T-shaped connecting blocks 301 is fixedly connected to one side of the two replaceable spindle heads 101 and the two outer spindle heads 102 .

[0033] Specifically: it is convenient to fix the T-shaped connecting block 301, and avoid affecting the stability of the T-shaped connecting block 301 and affecting the use of the ingot starter.

[0034] In one embodiment, the surfaces of the four T-shaped connecting blocks 301 are movably embedded in the four T-shaped slots 106 .

[0035] Specifically, the T-shaped connecting block 301 and the T-shaped slot 106 are engaged to facilitate fixing the replaceable spindle head 101 or the outer spindle head 102 .

[0036] Working principle: This ingot starter head needs to be adjusted in size according to needs before use. This ingot starter head includes a plurality of replaceable ingot heads 101 of different lengths. The T-shaped connecting blocks 301 at one end of the two replaceable ingot heads 101 can be inserted into the interior of the insertion grooves 105 on both sides of the ingot starter head body 1.

When the T-shaped connecting block 301 moves to the innermost side of the insertion groove 105, the T-shaped connecting block 301 slides toward the inside of the T-shaped groove 106, so that the T-shaped connecting block 301 is engaged with the inside of the T-shaped groove 106. At this time, the baffle 202 is no longer squeezed by the T-shaped connecting block 301, and returns to its original position under the action of the spring 203. In the initial position, one side of the baffle 202 will block the T-shaped connecting block 301 engaged in the T-slot 106. The T-shaped connecting block 301 on one side of the two outer ingot heads 102 is also engaged in the inner side of the T-slot 106 on one side of the two replaceable ingot heads 101 in the same way as above. The assembly of this ingot head is completed according to the needs. When disassembling, the baffle 202 inside the baffle groove 108 is bent and pressed to move the baffle 202 to the innermost side inside the extension groove 105, and then the T-shaped connecting block 301 inside the T-slot 106 is slid to the inside of the extension groove 105 to take out the replaceable ingot head 101 and the outer ingot head 102. This design avoids the problem that the ingot head for flat ingot casting is fixed and non-adjustable. Each new specification of ingot needs to be equipped with a set of new ingot heads, resulting in excessive procurement costs. At the same time, this ingot head is easy to install and disassemble.
