A mold with a cylinder ejector mechanism

Abstract

The invention discloses a die with an ejector sleeve ejection mechanism. The die comprises a lower code template used for fixing the die, a hot runner system arranged at the upper part of the lower code template, the ejector sleeve ejection mechanism which is arranged at the upper part of the hot runner system and used for ejecting a product, a lower template arranged at the upper part of the ejector sleeve ejection mechanism, an upper template arranged at the upper part of the lower template and an upper code template which is arranged on the upper template and used for fixing the die. According to the die with the ejector sleeve ejection mechanism, with the ejector sleeve ejection mechanism, a column at an arbitrary position in an injection molded product can be used as an ejector sleeve to be ejected, so that the use environment limited factor is greatly lowered; as the length of an ejector sleeve needle is shorted, the rick that the ejector sleeve needle is liable to break is reduced, and the service life of the ejector sleeve needle is prolonged; with addition of an ejector sleeve needle fixing insert to fix the ejector sleeve needle, the ejector sleeve needle is prevented from interfering with the hot runner system and can be rapidly changed during production and later maintenance, so that the labor cost and the maintenance cost are lowered, and the after-sales efficiency is improved.

Description

technical field [0001] The invention relates to the field of molds, in particular to a mold with a cylinder ejection mechanism. Background technique [0002] In traditional flip-chip molds, the most commonly used cylinder installation style is: the cylinder is fixed on the thimble panel, and the cylinder pin is fixed on the lower template. When the mold is opened, the oil cylinder drives the thimble panel and the thimble supporting plate to move, thereby driving the cylinder to eject the product, and the cylinder needle is fixed on the lower template to form the inner hole characteristics of the product column. Due to the increasingly strict requirements on product appearance, many products must use flip-chip hot runner molds. Under certain circumstances, the cylinder needle will often interfere with the manifold and cylinder of the hot runner, resulting in the failure to use the cylinder to form the product or inconvenient installation of the mold, and the cylinder needle ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a mold with a cylinder ejection mechanism, so as to overcome the interference between the cylinder needle and the manifold plate and cylinder of the hot runner in the existing traditional flip-chip mold, resulting in It is inconvenient to install the mold or can not be used to form products with cylinders, and the existing cylinder needles are too long and easy to break, and the cost is high
