Embodiment Construction

[0012] In order to better understand the technical solution of the present invention, it will be described in detail below through specific embodiments in conjunction with the accompanying drawings:

[0013] see figure 1 , a tilting casting mold for a cylinder head of the present invention includes a base 1 , a base frame, a hydraulic strut assembly and a mold assembly 3 .

[0014] The base 1 is set on the ground, and the mold assembly 3 is set on the base 1 .

[0015] The hydraulic strut assembly includes two bottom struts 21 and three horizontal struts 22 . Bottom struts 21 are arranged symmetrically on both sides of the base 1, and their tops are connected to both sides of the mold assembly 3; horizontal struts 22 are horizontally arranged on the top of the mold assembly 3; the mold assembly 3 is connected to the base frame through the horizontal struts. The horizontal struts 22 include three parallel struts 221, one end of the three struts 221 is connected to the mold as...

Abstract

The invention discloses a cylinder cover inclinable-pouring die which comprises a base, a bed frame, a hydraulic support rod assembly and a die assembly. The base is arranged on the ground, and the die assembly is arranged on the base; the hydraulic support rod assembly comprises two bottom supporting rods and three horizontal supporting rods; the bottom supporting rods are symmetrically arrangedon the two sides of the base, and the tops of the bottom supporting rods are connected to the two sides of the die assembly; the horizontal supporting rods are horizontally arranged at the top of thedie assembly; and the die assembly is connected with the bed frame through the die assembly. According to the cylinder cover inclinable-pouring die, the die assembly is connected with the base and thebed frame through the hydraulic support rod assembly, meanwhile, the die assembly can do overturning motion under assemblies of the hydraulic support rod assembly, the overall inclining process is stable, and the problems of turbulent flow and air entrapment slag clamping are solved; and by means of the cylinder cover inclinable-pouring die, the die assembly is assisted by an exhaust device and acooling device, a temperature field and an airflow field keep stable in the circulating process from pouring mold filling to cooling solidification to die opening and closing, and the product yield is improved.

Description

technical field [0001] The invention relates to a tilting casting mold for a cylinder head used in the field of automobile manufacturing. Background technique [0002] The cylinder head is mounted on top of the cylinder block, sealing the cylinder from above and forming the combustion chamber. It is often in contact with high-temperature and high-pressure gas, so it needs to withstand large thermal and mechanical loads. The aluminum alloy cylinder head cast by the existing casting process has defects such as pores and porosity in the cast product. How to improve the pass rate of the casting, improve the compactness of the structure of the cylinder head of the automobile engine, and improve its mechanical properties are the main goals of technicians. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a tilting casting mold for a cylinder head, which has a compact structure and can effectively ...
