Diesel engine body casting mold

Abstract

The invention relates to a diesel engine body casting mold. The diesel engine body casting mold comprises an upper mold plate and a lower mold plate, wherein a guide mechanism is arranged between the upper mold plate and the lower mold plate; the bottom of the upper mold plate is fixedly connected with an upper sealing plate; a lower sealing plate is arranged on the top of the lower mold plate; the upper sealing plate and the lower sealing plate define a diesel engine body casting cavity; and a diesel engine body tool is positioned in the diesel engine body casting cavity. The diesel engine body tool consists of an outer core body and an inner sand core, wherein a diesel engine body forming cavity is formed between the outer core body and the inner sand core; the outer core body is formed by splicing four diesel engine body housing core bodies; the inner sand core is positioned inside the spliced diesel engine body housing core bodies; the outer walls of the four diesel engine body housing core bodies are in tight contact with the inner wall of the diesel engine body casting cavity; the outer core body and the inner sand core can be dismounted from the diesel engine body casting cavity; and the structural shape and the specification of the diesel engine body in the diesel engine body forming cavity can be changed by changing the structure of the inner sand core.

Description

Technical field [0001] The present invention relates to the field of casting molds, in particular a diesel engine casting mold. Background [0002] The casting mold refers to the structural shape of the part to obtain a part of the part, and then put the sand type into the mold in advance, then the sand type is formed in the sand type cavity, and then The fluidic liquid is poured in the cavity, which can form the corresponding part shape after cooling the solidification. Both the current diesel engine is basically completed by casting molds. The raw materials used in the casting mold are generally molten metal, which summarizes the function of the current market existing diesel engine casting mold. Applicant discovers the current diesel engine casting mold. There are several technical issues that need to be solved in actual use: 1. When cast in the cavity, the diesel engine body is mainly formed by the core of the diesel engine body, the core is not detachable, the core and the m...

Problems solved by technology

The current diesel engine bodies are basically processed by casting molds. The raw materials used in casting molds are generally molten metals. The function of the existing diesel engine body casting molds in the market is summarized. The applicant found that the current diesel engine body casting molds In actual use, there are several technical problems that need to be solved: 1. When the diesel engine body is cast in the mold cavity, the structure of the diesel engine body is mainly completed through the core body on the inner wall of the mold cavity. The core body cannot be disassembled. The inner wall of the cavity is integrally formed, and this structure is only suitable for casting of one type of diesel engine body; 2. When pouring products, the cavity uses air holes to exhaust, which is easy to block; 3. During the process of opening and closing the mold, the movement of the upper mold is unstable ; This patent further improves the structure of the diesel engine body casting mold
