Automatically-controlled injection mold clamping device

Abstract

The invention relates to the technical field of injection molding clamps, and discloses an automatically-controlled injection mold clamping device. The automatically-controlled injection mold clamping device comprises a shell, wherein a converter is fixedly connected to the interior of the shell, and evenly-distributed clamping grooves are formed inside the converter; starting switches are fixedly connected to the interiors of the clamping grooves, two symmetrical clamping parts are movably connected to the interior of each clamping groove, and permanent magnets are fixedly connected to the interiors the clamping parts; and six evenly-distributed moving grooves are formed inside the converter. According to the automatically-controlled injection mold clamping device, through interaction of electromagnetic sheets and the permanent magnets, when the electromagnetic sheets are electrified, the clamping parts are driven to overcome the elastic force effect of springs I to clamp molds; and meanwhile, through mutual cooperation of telescopic blocks and the molds, when clamping is completed, electrode columns are controlled to be electrified, and electrorheological fluid inside liquid cavities is changed into a solid state from a liquid state, so that the movement of the clamping parts is limited, the automatic clamping function of the products is realized, and the stability of the clamping parts is enhanced.

Description

technical field [0001] The invention relates to the technical field of injection molding fixtures, in particular to an automatically controlled injection mold clamping device. Background technique [0002] With the advancement of science and technology and the development of production technology, many plastic products are integrally molded by injection molding machines. During the injection molding process, the mold needs to be clamped to prevent the movement and loosening of the mold. Demoulding the injection molded parts, however, in the process of clamping, the clamping is often unstable and needs to be clamped manually, which greatly reduces the efficiency of production and is not conducive to the use of users. [0003] During the clamping process of the injection mold, the clamping part is often loosened and unstable due to the vibration of the clamping part or the disturbance of the external force. At the same time, the clamping and unclamping of the mold requires man...
