Uniform opening and closing cooling fin casting mold

Abstract

The invention discloses a heat-dissipation-fin casting mold capable of being opened and closed uniformly. The heat-dissipation-fin casting mold comprises at least one pair of clamping boards used for clamping heat dissipation fins, limiting sliding blocks are connected between every two adjacent clamping boards, and the two ends of a clamping device are connected with hydraulic cylinders. One end of each limiting sliding block is fixed to the corresponding clamping board, a sliding groove is formed in the other end of each limiting sliding block, and a sliding block on the clamping board on one side adjacent to the corresponding clamping board is arranged inside the corresponding sliding groove. By means of the hydraulic cylinders and the clamping board which are connected in series, uniform opening and closing and one-off automatic clamping of the heat dissipation fins are achieved, the problem that the production rate is low because workers clamp the heat dissipation fins one by one is solved, and production efficiency is improved. The limiting sliding blocks connected between every two adjacent clamping boards enable the mold to be opened and closed uniformly, and the problem that it is difficult for the heat dissipation fins to be arranged in the mould because of deformation is solved. When the bottoms of the heat dissipation fins need to be inlaid inside heat dissipation shells in a cast mode, the heat dissipation fins are clamped tightly through the clamping boards, and therefore it can be prevented that metal liquid permeates into the clamping boards, so that the mould is blocked and cannot be used.

Description

technical field [0001] The invention relates to the field of heat dissipation equipment manufacturing, in particular to a casting mold for heat dissipation fins that can be opened and closed evenly. Background technique [0002] With the continuous development of electronic technology, the power of equipment is getting higher and higher, and the requirements for heat dissipation are getting higher and higher. In addition, outdoor electronic equipment needs waterproof, windproof and other protection. Outdoor electronic equipment often uses non-ferrous alloy casting shells as shells. The general design is die-casting shells. The inner space formed by the box cover is used to place printed circuit boards (PCB) or other equipment. , to play a protective role, and design cooling fins on the outside of the shell to help the equipment dissipate heat naturally. [0003] The heat dissipation fins of the existing electronic equipment need to wait for the heat dissipation shell of the...
