Deformation correcting device

Abstract

The invention discloses a deformation correcting device which comprises a fixing device, a cylinder and a control box. The fixing device comprises a fixing plate, a connecting arm and a correcting plate, the fixing plate is arranged at one end of the connecting arm, the correcting plate is arranged at the other end of the connecting arm, the cylinder comprises a push rod and a push head, the push rod penetrates the fixing plate, the push head is fixed at one end, facing the correcting plate, of the push rod, and the control box is electrically connected with the cylinder and controls the push rod and the push head to move up and down. Strength and time of pressure applying of the cylinder can be accurately controlled through the control box, so that accurate correcting effect is guaranteed.

Description

technical field [0001] The invention relates to the field of mold correction, in particular to a deformation correction device. Background technique [0002] At present, injection molding has developed to a very mature stage, and general injection molding defects can be realized by correcting the process and mold. But there is a class of common defects: warpage is unavoidable in the actual production process. Warpage is a common type of injection defect in the process of injection molding. It means that the shape of the injection molded part deviates from the basic shape of the mold cavity. The previous solutions for warping and deformation mainly included one-to-one correspondence, modification of the mold structure, modification of the molding conditions, or modification of the fixture structure, etc. These solutions not only have high cost, poor economy, and low efficiency, but also take a long time to deal with. no significant effect. [0003] At present, the effect o...

But there is a class of common defects: warpage is unavoidable in the actual production process

The previous solutions for warping and deformation mainly included one-to-one correspondence, modification of the mold structure, modification of the molding conditions, or modification of the fixture structure, etc. These solutions not only have high cost, poor economy, and low efficiency, but also take a long time to deal with. no significant effect

[0003] At present, the effect of the post-correction method adopted by some units is more obvious. However, because there is no special correction device for injection molded parts on the market, many companies use simple deformation correction fixtures and use manual pressing for correction. Accurate control is achieved, and the labor intensity is high, there are still deviations in personnel operation methods, and the accuracy is unstable, which is not conducive to popularization and use
