Abstract

The invention provides an internal stress soaking testing machine of a plastic product, relates to the field of detecting instruments and apparatus for laboratories, and aims at overcoming the defect that the existing internal stress soaking test of the plastic product can only be operated by a manual manner. The testing machine comprises a product transfer cage, a solvent vessel, a flushing device, a first time relay for controlling the timing of the soaking time, and a second time relay for controlling the timing of the flushing time; the product transfer cage is arranged above the solvent vessel and the flushing device and is driven through a vertical driving mechanism to move in the vertical direction so as to extend into / be lifted away from the internal part of the solvent vessel or a flushing area of the flushing device; the vertical driving mechanism is driven through a first horizontal driving mechanism to move in the horizontal direction so as to drive the product transfer cage to move to be above the solvent vessel or the flushing device; a vessel cover is arranged on the solvent vessel, and the vessel cover is driven through a second horizontal driving mechanism to move in the horizontal direction so as to open or close the solvent vessel. With the adoption of the testing machine, the testing result is accurate.

Description

technical field [0001] The invention relates to the technical field of laboratory detection instruments, in particular to an instrument for performing a solvent immersion test on the internal stress formed by the combination of material molecules during the injection molding process of plastic products. Background technique [0002] Plastic internal stress refers to an internal stress generated by factors such as orientation of macromolecular chains and cooling shrinkage during plastic melt processing. The essence of internal stress is the unbalanced conformation formed by the macromolecular chain during the melting process. This unbalanced conformation cannot immediately return to the balanced conformation suitable for the environmental conditions when it is cooled and solidified. The essence of this unbalanced conformation is a A reversible high-elastic deformation, and the frozen high-elastic deformation is usually stored in the form of potential energy in plastic product...
