Mold capable of quickly positioning and preventing looseness for casting engine cylinder head

Abstract

The invention discloses a mold capable of quickly positioning and preventing looseness for casting an engine cylinder head. The mold comprises a bottom plate, wherein a fixed mold body is fixedly connected to the top of the bottom plate, a movable mold body is located over the fixed mold body, a connecting pipe is arranged at the top of the movable mold body, inclined grooves are formed in the left side and the right side of the surface of the connecting pipe, a material injection pipe is slidably connected into the connecting pipe, an arc groove is formed in the surface of the material injection pipe, a threaded sleeve is in threaded connection with the surface of the connecting pipe, a rotating wheel is fixedly connected to the surface of the threaded sleeve, and positioning balls are slidably connected into the inclined grooves. According to the mold, the material injection pipe can be prevented from rotating or loosening, and the problems that the existing casting mold is difficultto quickly and accurately position when being connected and fixed with an injection molding machine, a gap is easily formed between the mold and the injection molding machine, so that a cast engine cylinder head has a convex mark, and the qualification rate of the engine cylinder head is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of engine cylinder head production, in particular to a fast-positioning and loose-preventable mold for casting an engine cylinder head. Background technique [0002] A generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator. Generators are then converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. There are many forms of generators, but their working principles are based on the law of electromagnetic induction and the law of electromagnetic force. [0003] The engine cylinder head is generally made by mold casting, but the e...

Problems solved by technology

[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a mold for engine cylinder head casting that can be quickly positioned and prevented from loosening. It is difficult to quickly and accurately position the casting mold when it is connected to the injection molding machine, which may easily lead to gaps between the mold and the injection molding machine, resulting in raised marks on the casted engine cylinder head, which affects the qualified rate of the engine cylinder head
