[0009] According to a further optimized solution, the first bracket, the second bracket, the third bracket and the cylinder head body are integrally cast, and the first bracket, the second bracket and the third bracket are vertically arranged to the cylinder head body.

[0010] According to a further optimized solution, the first bracket, the second bracket and the third bracket are arranged in a triangle on the cylinder head body.

[0011] According to a further optimized solution, an annular clamping groove is formed on the first bracket, the second bracket and the third bracket, and the opening of the annular clamping groove is rectangular.

[0012] According to a further optimized solution, the first support, the second support and the third support are all cylinders.

[0013] A further optimized solution is a mold suitable for an engine cylinder head with a latch according to the above claims, comprising a mold body, on which a locking structure for locking a first latch, a second latch and a third latch is installed.

[0014] A further optimized solution is that the locking structure includes locking claws arranged opposite to each other, an installation area is opened on the mold body, a pair of the locking claws are installed in the installation area and are rotatably connected to the mold body, one end of the pair of locking claws arranged in the installation area has a clamping portion, the clamping portion is clamped with an annular clamping groove, the other end of the pair of locking claws extends out of the outside of the mold body, and a spring is fixedly connected between them.
