AI Technical Summary
Technical Problem
During the production process of existing cylinder head molds, tar cannot be effectively discharged, resulting in problems with product appearance and quality, and there is a lack of an effective exhaust system.
Method used
A cylinder head outer mold combustion chamber structure is designed, which includes a combustion chamber, an exhaust hole, an exhaust plug, a tar pipe and a tar collection box. Tar gas is discharged through the exhaust plug, flows into the tar pipe and is finally collected in the tar collection box, thereby achieving effective tar discharge.
Benefits of technology
Effectively discharge the tar in the mold, improve product qualification rate, reduce employee complaints, and improve the production environment.

Abstract
The utility model discloses a cylinder cover outer mold combustion chamber tar discharging structure which comprises a cylinder cover outer mold. The combustion chamber is evenly distributed on the cylinder cover outer mold, the exhaust holes are evenly formed in the combustion chamber, the exhaust plugs are evenly installed on the exhaust holes, the tar receiving pipes are symmetrically connected to the lower end of the combustion chamber, and the tar discharging channel is formed in the combustion chamber and connected with the tar receiving pipes. The ejector plate is arranged below the cylinder cover outer mold; the tar collecting box is fixed on the ejector plate and is positioned below the tar receiving pipe; when a cylinder cover mold is cast, a certain amount of sand cores are placed, the sand cores contain resin, a large amount of tar and gas generated by the sand cores during mold production are discharged from the venting plug on the top face of the combustion chamber, and the tar flows into the tar discharging channel, then flows into the tar receiving pipe and finally is discharged into the tar collecting box from the tar receiving pipe. Most tar generated in the mold can be discharged.
