Hough mold

Abstract

The invention relates to the field of molds, and discloses a Hough mold. The Hough mold comprises an upper mold and a lower mold, wherein a Hough block is arranged between the upper mold and the lowermold; the Hough mold further comprises a wedge block, a first wear-resistant block and a second wear-resistant block, wherein the wedge block, the first wear-resistant block and the second wear-resistant block are sequentially arranged, and the second wear-resistant block is arranged in a mounting groove of the Hough block; and a groove is formed in the wedge block, the first wear-resistant blockpart is located in the groove, and the first wear-resistant block extends outwards to form a first distance along the groove. The first wear-resistant block extends outwards 2 mm along the wedge block, so that the first wear-resistant block can be sufficiently pressed against the second wear-resistant block, each single Hough block is tightly fixed together, the single Hough block is not easy toloosen in the production process, and the product percent of pass is effectively improved; and the installation process of the mold is rapid and convenient, the production cost of the mold is saved, meanwhile, the machining period of the mold is shortened, the production qualified rate of products is improved, and the economic benefit is better.

Description

technical field [0001] The invention relates to the field of moulds, more specifically to Hough moulds. Background technique [0002] The mold is a tool that makes the blank into a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and engineering plastics, rubber, ceramics, etc. In the molding process of compression molding or injection molding of products such as The mold has a specific contour or inner cavity shape, and the application of the contour shape with cutting edges can separate the blank according to the contour line shape, and the application of the inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into ...

AI Technical Summary

Problems solved by technology

Due to the tight fit between the wedge and the half surface, the cumulative error in the processing of the wedge causes a gap between the two wear-resistant plates, which cannot be tightly fitted, and the wear-resistant block cannot effectively compress the half, thus In the process of product production, Huff is easy to loose, resulting in high product scrap rate

The length of the wear-resistant block installation groove on the Haff of the traditional injection mold is the same as the length of the wear-resistant block. In the process of processing the mold, it is necessary to use a smaller tool for corner cleaning, which leads to an increase in the processing time of the mold, and the mold assembly prone to interference in the process
