Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1~Figure 4 , the embodiment of the present invention includes:

[0026] A counter-compensation production process for injection-molded plastic products, comprising the following steps:

[0027] A. Analyze the reasons that will lead to warpage of injection molded products. The reasons for warpage of products include but are not limited to uneven shrinkage, uneven cooling and molecular orientation of materials, especially the uneven shrinkage caused by corners and the difficulty in arranging cooling...

Abstract

The invention discloses an injection molding plastic product reverse compensation production process. The process includes following steps: analyzing reasons be going to cause buckling deformation ofa plastic product; aiming at the reasons causing buckling deformation of the product, analyzing an area where buckling deformation of the product possibly occurs; after the area is determined basically, properly reserving steel for the area in the process of mold design for the convenience of subsequent mold maintenance; acquiring a deformation sample plate through first-time mold testing, and acquiring 3D sample plate CAD data of the deformation sample plate by means of three-dimensional scanning reverse engineering; performing preliminary gluing reverse compensation on buckling deformation by means of mirroring and reverse surface forming on mold 3D; after second-time mold testing, confirming reverse compensation effect by means of visual inspection and detection. By the above mode, theprocess is formulated mainly for the defect of buckling deformation of the plastic product, mold maintenance efficiency is improved substantially, maintenance cost is lowered, and the defect of buckling deformation of the product is improved effectively.

Description

technical field [0001] The invention relates to the technical field of plastic product production, in particular to a counter-compensation production process for injection-molded plastic products. Background technique [0002] With the rapid development of the plastics industry, the application scope and demand of plastic products are also expanding, and people have put forward higher and higher requirements for the quality and precision of plastic products. [0003] Injection molding has become one of the main molding methods for plastic products due to its advantages of high production efficiency, short cycle time, ability to form products with complex shapes and high dimensional accuracy requirements. In the injection molding of plastic products, warpage is one of the most common and difficult to completely eliminate defects. There are many factors that cause it, which has a great impact on the appearance quality, performance, size and assembly accuracy of the product. E...
