Die horizontal positioning device and method for positioning die

Abstract

The present invention provides mold horizontal positioning equipment which comprises a first splint, a second splint, a guide rail and a horizontal positioning piece, wherein, the first splint and the second splint are oppositely arranged parallel, the first splint is perpendicularly fixed on one end of the guide rail, the second splint penetrates the other end of the guide rail in a sliding way; the horizontal positioning piece is arranged between the first splint and the second splint and comprises a container with a transparent hollow cavity and a reference object which are arranged on the surface of the first splint corresponding to the second splint; liquid is contained in the container; the reference object is at least one scale mark or one zero line being vertical to the guide rail; and the container comprises a bottom surface which is used for leaning with the top surface of the pending fixed mold, wherein the shape of the bottom surface is corresponding to the shape of the top surface of the pending fixed mold. The mold horizontal positioning equipment can conveniently adjust the mold horizontal positioning equipment to make sure the mold is precisely horizontally arranged and fixed. The invention also provides a mold positioning method.

Description

technical field [0001] The invention relates to the field of mold technology, in particular to a mold horizontal positioning device and a method for positioning the mold. Background technique [0002] Molds are more and more widely used to form precision products of plastic, glass, metal and other materials. Among them, injection molding is a process of filling molten molding materials into a closed mold cavity under high pressure to produce products of expected shape. It has the advantages of low cost, high efficiency, and high precision, and is widely used in the production of plastic materials. , especially injection molding small precision components, such as micro lenses, lens barrels and other products. See the paper "Injection molding of binary optical elements" published by Robert D.TeKolste et al. in the 1995 SPIE System, Design, Fabrication, and Applications of Precision Plastic Optics Proceedings (Design, Fabrication, and Applications of Precision Plastic Optics ...

AI Technical Summary

Problems solved by technology

However, if the level of the installed mold is not good, that is, the mold is in an inclined state, when the injection molding is performed, the injected plastic will flow into the inclined mold, and the symmetry of the finished product will be poor, which will affect the quality of the finished product. The levelness of the mold is an important parameter that affects the quality of the final injection product

At present, when the mold is put into the injection molding machine, it is generally determined by visual inspection whether the injection molding mold is in a horizontal state. However, the visual inspection result is greatly affected by human subjective factors, which will directly affect the accuracy of levelness measurement and reduce the final level.
