Problems solved by technology
[0002] Originally, when molds were used to produce shells, the products produced would have problems of substandard quality, lack of hardness, and a large number of internal air shrinkage cavities. In order to solve the above problems, different core-pulling structures were designed on the molds, and in order to ensure that the shells It is very necessary to design a kind of core pulling that is connected with this part

Embodiment
[0037] When it is necessary to produce the shell, first install the entire mold on the die-casting machine, and then carry out debugging. After the debugging is completed, the upper mold base 1 and the lower mold base 4, as well as the upper mold core 2 and the lower mold core 3 are first closed. After the completion, the molten aluminum liquid is injected into the mold cavity 15. The aluminum liquid enters the mold from the sprue bushing 13, and the aluminum liquid is transported through the flow channel. The aluminum liquid will fill the mold cavity 15 and pass through the die-casting machine in Keep the pressure in the mold. After the completion, start to input cooling water into the cooling pipe in the lower mold base, so that the mold will cool down. After the shell is formed, open the mold, and then firstly, the second linkage core pulling 16 will perform the core pulling action, and then start at the same time The first linkage core-pulling 17 and the rear core-pulling s...

The invention relates to a die-casting mold provided with linkage pull cores. A lower mold core is installed on the upper end face of a lower mold base, an upper mold base and the lower mold base are arranged in a stacked mode, and a mold cavity is formed between the middle of an upper mold core and the lower mold core; the first linkage pull core and the second linkage pull core are arranged on the right portion between the upper mold base and the lower mold base, the second linkage pull core is located at the corner of the front portion of the lower mold base, the core inserting end of the second linkage pull core obliquely extends toward the mold cavity and is inserted into the mold cavity, the first linkage pull core is installed horizontally, a rear pull core structure with the pull core inserted into the mold cavity is arranged on the rear portion between the upper mold base and the lower mold base, and a lower base inclining core pulling structure with the core pulling end inclining upwards and inserted into the mold cavity is arranged on the left portion of the lower mold base. The die-casting mold provided with the linkage pull cores has the advantages of being simple in structure and high in production efficiency, ensuring product quality and reducing mold manufacturing cost.
Description
technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a die-casting mold equipped with linkage core pulling. Background technique [0002] Originally, when molds were used to produce shells, the produced products would have problems of substandard quality, lack of hardness, and a large number of air shrinkage cavities inside. In order to solve the above problems, different core-pulling structures were designed on the molds, and in order to ensure that the shells It is very necessary to design a core-pulling that is docked with the corner part. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a die-casting mold equipped with linkage core pulling, which has the characteristics of simple structure, high production efficiency, guaranteed product quality, and reduced mold manufacturing cost. [0004] The technical solution adopted by the present invention to solve t...
