Pultrusion sectional material mould with embedded core mould

Abstract

The invention provides a pultrusion sectional material mould with an embedded core mould. The pultrusion sectional material mould comprises an upper mould body, the core mould and a lower mould body. The upper mould is arranged on the lower mould, and the lower end face of the upper mould is attached to the top end face of the lower mould. A positioning groove is formed in the lower end face of the upper mould. The core mould is embedded in the positioning groove and the upper mould and is in connection with the upper mould through a first bolt. A plurality of demoulding bolt holes used for pushing out the core mould are uniformly formed in the upper mould. The upper mould and the lower mould are positioned through a positioning pin and connected through a second bolt. The upper mould, the core mould and the lower mould together form moulding grooves used for making a sectional material. Rectangular grooves are formed in end face mould close joint of the upper mould and the lower mould correspondingly, and corresponding rectangular grooves form mould opening grooves together. A plurality of temperature measuring holes are formed in the side of the upper mould. According to the pultrusion sectional material mould with the embedded core mould, the embedded core mould design is adopted, positioning is accurate, the number of the parting faces and the assembling faces are small, the assembling difficulty is low, the close joint is tight, and the special demoulding bolt holes for pushing out the core mould are designed to reduce the difficulty of taking out the core mould.

Description

technical field [0001] The invention relates to a pultrusion profile mold with an embedded core mold. Background technique [0002] The pultrusion process is still in the stage of rapid development. From the perspective of domestic and foreign development trends, it is mainly for the production of large-size, complex cross-section, and thick-walled parts. However, there are still many problems in the design of pultrusion dies. For example, most pultrusion dies have low corrosion resistance, and the surface layer is easy to fall off, which affects the yield. , the seam is not tight, it is not easy to clean, and the work efficiency is reduced. [0003] The above problems should be considered and solved during the design and use of pultrusion profile dies. Contents of the invention [0004] The purpose of the present invention is to provide a pultrusion profile mold with an embedded mandrel, which has tight seams, reduces demoulding resistance, is easy to clean, and solves ...
