Power Design Method for Injection Molded Parts and Its Heating Tube

Abstract

The invention relates to the field of moulds, and provides a power design method for injection mold parts and heating pipes thereof. The injection mold part provided by the present invention includes a mold body and a plurality of heating pipes. The mold body has a plurality of first mold cavities distributed in m rows and n columns. The first mold cavities in each row are distributed along the first direction, and the first mold cavities in each row are first The mold cavity is distributed along the second direction, at least m+1 of the multiple heating tubes are distributed into m+1 rows along the first direction, and at least n+1 of the multiple heating tubes are distributed into n+1 along the second direction The plurality of heating tubes encloses m×n spaces, and each first cavity corresponds to each space one by one. The present invention designs the power relationship of each heating tube according to the dimensional parameters among the first cavity, the end face and the heating tube, which not only helps to make each first cavity receive uniform heating, but also helps to improve the molding quality, and also helps to reduce heating The number of design experiments of the tubes is beneficial to quickly determine the power of each heating tube.

Description

Technical field [0001] The present invention relates to the field of molds, and in particular to a power design method of injection molding components and its heating tubes. Background technique [0002] The mold mainly includes a mold and a heating tube assembly, a mold having a cavity, a heating tube assembly generating heat to heat the molding material in the mold cavity. [0003] However, in the case where the mold has a plurality of cavities, the power setting of the heating tube assembly can easily lead to uneven heat in each molding material, in order to make the molded material in each of the mold cavities are uniform, often need Multiple experimental corrections in the arrangement position and power of the heating tube, resulting in a large set of difficulty in the heating tube assembly. Inventive content [0004] One of the objects of the present invention is to provide an injection molding member that is simple and facilitating uniform thermally heat in the first mold...

Problems solved by technology

[0003] However, when the mold body has multiple cavities, improper power setting of the heating pipe assembly will easily lead to uneven heating of the molding materials in each cavity. In practice, in order to make the molding materials in each cavity evenly heated, it is often necessary The layout position and power of the heating tubes were corrected many times, which made it difficult to set up the heating tube components
