Abstract

The invention discloses a needle-drawing injection mold for a front mold slide block. The front mold slide needle injection mold includes a hot runner plate, a front mold, a rear mold and inserting needles. The front mold is arranged between the hot runner plate and the Between the rear molds, the front mold is provided with a slider that can slide relative to the front mold, the slider is engaged with the rear mold, the insert pin is arranged on the hot runner plate and It can pass through the front mold, the slider and the rear mold, and when the hot runner plate moves, it drives the insert pins to move out of the rear mold, and at the same time, the hot runner plate drives the front mold Move, the front mold drives the slider to move, so that the slider is separated from the rear mold. In the technical solution of the present invention, by changing the core-pulling structure of the traditional injection mold, the structure of the entire injection mold becomes compact, and the production cost of the entire injection mold is also reduced.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a needle-drawing injection mold for a front mold slider. Background technique [0002] Nowadays, with the development of industry, more and more molds, especially injection molds, need to be applied in the industrial production process. At present, the injection mold mainly uses an external drive structure to pull the core of the injection mold, so as to realize the separation of the mold and take out the product. Usually, the injection mold with an external drive structure not only has a large shape, but also requires more external connectors. For example, the drive mechanism is an oil cylinder, which requires oil cylinder brackets, oil pipes, etc., making the structure of the entire mold complex. The cost of the mold is increased. In addition, the insert pins are fixed on the cavity, which requires high mold clamping precision. The insert pins are prone to decrease in...
