[0002] Intake cylinder head (if attached figure 1 (shown) is a component on the piston cylinder, which mainly adopts the hot die casting process to die-cast the molten aluminum in the mold, and obtain a rough billet after cooling and demoulding, and then perform drilling processing after deburring , to obtain the finished product; the drilling process is mainly carried out with a vertical electric drill. In order to ensure the verticality of the cylinder head installation hole, when drilling, the cylinder head is directly clamped on the vise for drilling. Due to the small size and shape of the intake cylinder head Irregularity, can not guarantee the precision requirements and high interchangeability of the mounting holes, which brings certain difficulties and uncertainties to the later assembly, and the size positioning is all done by manual operation, making it difficult to clamp

Embodiment Construction
[0011] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0012] like figure 2 , image 3 As shown, the lower mold for drilling the intake cylinder head is used for such as figure 1 The shown air intake cylinder head 1 is subjected to drilling processing, and the lower mold for drilling the vertical holes of the air intake cylinder head includes a vertical hole mold, and the vertical hole mold includes a base 2, and a horizontal through groove is opened on the base 2 3. Inverted L-shaped cantilevers 4 are arranged opposite to each other on both sides of the through groove 3, so that a cross-shaped concave hole 5 is formed between the base 2 and the two cantilevers 4, and a horizontal section of the cantilever 4 is provided with Vertical through hole 6 , the position and diameter of the through hole 6 match the vertical mounting hole 7 on the intake cylinder head 1 . When in use, directly push the intake cylinder head 1 ...

The invention discloses a lower mold for drilling a vertical hole of an air intake cylinder head, which comprises a base, and a horizontal through groove is provided on the base, and inverted L-shaped cantilever arms are arranged opposite to each other on both sides of the through groove, so that the A cross-shaped concave hole is formed between the base and the two cantilevers. A vertical through hole is opened on the horizontal section of the cantilever. The position and diameter of the through hole match the vertical mounting hole on the intake cylinder head. The advantages of the present invention are: the present invention adopts a special vertical hole mold, which effectively improves the clamping stability and precision in the drilling process of the intake cylinder head; High work efficiency and good practicability.
Description
technical field [0001] The invention relates to the technical field of cylinder head processing, in particular to a lower mold for drilling vertical holes of an air intake cylinder head. Background technique [0002] Intake cylinder head (if attached figure 1 (shown) is a component on the piston cylinder, which mainly adopts the hot die casting process to die-cast the molten aluminum in the mold, and obtain a rough billet after cooling and demoulding, and then perform drilling processing after deburring , to obtain the finished product; the drilling process is mainly carried out with a vertical electric drill. In order to ensure the verticality of the cylinder head installation hole, when drilling, the cylinder head is directly clamped on the vise for drilling. Due to the small size and shape of the intake cylinder head Irregularity cannot guarantee the accuracy requirements and high interchangeability of the mounting holes, which brings certain difficulties and uncertainti...
