Mold opening mechanism

Abstract

The invention belongs to the technical field of molds, and particularly relates to a mold opening mechanism. The mold opening mechanism comprises an I-shaped block installed on a front mold and a guide rod installed on a fixed mold. The I-shaped block comprises a transverse strip and an inverted-T-shaped block. Inverted-L-shaped clamping blocks are arranged below the transverse strip and located on the two sides of the inverted-T-shaped block correspondingly. The inverted-L-shaped clamping blocks are matched with the inverted-T-shaped block, the upper end face of a supporting block is providedwith a third groove, the rear portion of a lever is located in the third groove, the lever and the supporting block are hinged in the third groove, the rear end of the lever is hinged to an inclinedinsert, the inclined insert is connected with an inclined insert needle, and a limiting block and the supporting block are installed on the fixed mold. The mold opening mechanism is simple, practical,silent, free of noise, small in occupied space and capable of being applied to molds of small products, an injection molding production machine table is small, operation and maintenance are simple, the problem that mold injection molding forming cannot be achieved since the space is small can be avoided for the characteristics that small products are provided with small inclined holes or invertedbuckles, the cost is greatly saved, and product production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of molds, and in particular relates to a mold opening mechanism. Background technique [0002] Accompanied by the rapid development of computer-aided design technology and the promotion of 5-axis machining centers. Consumers have higher and higher requirements for product quality and functions. Product designers can use 3D design software to arbitrarily complicate the product structure. When some traditional mold injection molding cannot be realized, the most expensive product production The solution is 3D printing technology. [0003] In the mold and injection molding industry, the mold manufacturing cost is directly proportional to the mold size and structure complexity. For products with the same dimensions, on the premise of satisfying the product quality, the weight of the mold should be made as light as possible to reduce the cost of purchasing steel, and the structure should be simplified as much as...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a simple and practical, quiet and noise-free, and small space occupation, which can be applied to the mold of small products, so that the injection molding production machine can be miniaturized, and the operation and maintenance can be simplified. The small oblique hole or undercut feature of small products can avoid the problem that the injection molding of the mold cannot be realized due to the small space, which greatly saves the cost and improves the production efficiency of the product.
