A mold with automatic cooling and heat dissipation structure

Abstract

The invention discloses a mold with an automatic cooling and heat dissipation structure. The mold comprises a mold body. Cooling holes are formed in the inner wall of the mold body. The cooling holes communicate with a pipeline. The pipeline communicates with a circulating pump. The circulating pump is electrically connected with a control mechanism. The control mechanism is electrically connected with a power source. By the adoption of the mold with the automatic cooling and heat dissipation structure, when the temperature of the mold is higher than the preset value, a first rocking arm is compressed by a first spring and lifted up, a second rocking arm is not in contact with a terminal, a shell is heated when in surface contact with the mold body, and gas in the shell is heated and expands to push a piston to move upwards; and after the preset value is exceeded, the first spring is compressed, a second spring pulls the right end of the second rocking arm to make the second rocking arm tightly attached to the terminal, a magnet attracts iron fixed to the first rocking arm, the second rocking arm communicates with the terminal, the power source supplies power to the circulating pump, the shell is started automatically, and the mold body is cooled by the circulating pump.

Description

technical field [0001] The invention relates to the field of molds, in particular to a mold with an automatic cooling and heat dissipation structure. Background technique [0002] During the use of the mold, high temperature is often generated due to long-term use. High temperature will cause deformation of the mold and seriously affect the precision of parts processing. Therefore, it is necessary to cool down the mold with too high temperature in time. [0003] In the patent specification whose publication number is CN205255447U, a mold heat dissipation assembly is disclosed, which belongs to the mold field, and includes a water-cooled heat dissipation pipe, a water tank and a water circulation power pump; And the water circulation power pump is set in the circuit of the water-cooling heat pipe to circulate heat; this kind of mold heat dissipation component also includes an independent heat dissipation rod, which is inserted into the gap of the product in the mold to dissip...
