Description
Technical Field
The utility model relates to a plastic mold technical field specifically is a novel automatic mechanism of stub bar that cuts off of plastic mold.
Background
A plastic mold is a tool for producing plastic articles and is formed from several component parts, the combination of which has a molding cavity. During injection molding, a mold is clamped on an injection molding machine, molten plastic is injected into a forming mold cavity and is cooled and shaped in the cavity, then an upper mold and a lower mold are separated, a product is ejected out of the mold cavity through an ejection system and leaves the mold, finally the mold is closed again for next injection molding, and the whole injection molding process is carried out in a circulating mode. Generally, a plastic mold is composed of a movable mold and a fixed mold, the movable mold is mounted on a movable mold plate of an injection molding machine, and the fixed mold is mounted on a fixed mold plate of the injection molding machine. And when the mold is opened, the movable mold is separated from the fixed mold so as to take out the plastic product. The product ejected from the die cavity and the runner glue inlet point are connected together after being demoulded, and need to be manually and manually trimmed and cut, and the manual trimming glue inlet point force is different from the mode every time, so that the residue of each product is different, and the traditional glue inlet trimming is more complicated and affects the appearance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an enable the mould beat behind the product faster realization runner material and product separation, better saving workman operating time, the automatic mechanism of stub bar of disconnected stub bar of the unanimous novel plastic former of disconnected tangent point every product simultaneously to solve the problem of proposing among the above-mentioned background art.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a novel automatic mechanism of stub bar that breaks of plastic mold, includes mould, lower mould, still includes mould benevolence, slider, slide wedge, mould benevolence fix on lower mould top side, mould benevolence on be equipped with a plurality of mould die cavities, slider one end locate in mould benevolence and with mould benevolence slidable setting, the slider on be equipped with the runner of being connected with a plurality of mould die cavities, the other end of slider be equipped with slide wedge bottom complex slide, the slide wedge top fixed with last mould.
Furthermore, one side of the top side of the lower die is provided with a slide block inlet and outlet, the slide block inlet and outlet extends into the die core to form a slide block groove for placing a slide block, and a slide bar and a slide groove which are matched with each other are arranged between the slide block and the slide block groove.
Furthermore, the two sides of the sliding block are provided with limiting grooves, and the lower die is provided with a pressing strip stop block matched with the limiting grooves. The effect of this scheme layering dog is injectd the mounted position and the slip length of slider.
Furthermore, the die core is provided with 4 die cavities which are symmetrically distributed on two sides of the sliding block.
Furthermore, the slide way of the slide block is an inclined slide way, and a return spring is arranged between the slide block and the die core. The reset spring of the scheme can drive the sliding block to reset when the wedge moves downwards.
Furthermore, the wedge upper end is perpendicular to last mould and adopts the thread tightening, the wedge bottom is in the slant stretches into the slider slide.
The scheme is that the material breaking head structure consists of an upper die, a lower die, a sliding block, a die core, an inclined wedge, a pressing strip stop block and a screw; firstly, all accessories are arranged in a matching groove of a mold to be assembled smoothly (the oblique wedge is fixed on the upper mold by a screw, and the sliding block is fixed on the lower mold), when the mold is opened up and down after injection molding is finished, the oblique wedge is fixed on the upper mold and the sliding block is fixed on the lower mold, and the sliding block is driven by the oblique wedge to move backwards due to the inclination of the oblique wedge, but the oblique wedge is not separated from the sliding block to be contacted, so that the sliding block can break a glue feeding point material head, and the glue feeding material head is completely and automatically broken when a product is ejected; after the product is taken out, the upper die is pressed down, the wedge moves downwards along with the upper die, and the slide block finally completes resetting under the action of the reset spring.
Compared with the prior art, the beneficial effects of the utility model are that:
the automatic trimming machine improves the original complicated manual independent trimming of the glue feeding head, realizes automatic trimming of the glue feeding head, ensures consistent force of the product at the glue feeding point, ensures consistent appearance, does not need manual trimming, and saves a large amount of manpower and material resources during mass production.
