Description
Technical field
The utility model relates to a kind of injection mold guide pillar order stripping mechanism, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, for example during the plastic product of similar containers, the structure of the traditional injection moulding mould normally core of mould stretches into the product inwall; The die cavity of mould is coated on the product outer wall, and the gap between core and the die cavity constitutes the die cavity of product, and mould structure is simple; Handling ease, therefore, people process the die cavity and the core of many (more than two) in a width of cloth mould; Make many products of an injection moulding of mould, enhance productivity.But, in actual production, because the plastic product that adopts injection mold to produce; One (surplus) material handle must be arranged on every product, and the material handle is stayed in runner and the cast gate, is connected with product; Therefore; Before product stripping, must solve the material handle earlier and separate the problem that product could be deviate from smoothly with product.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, a kind of guide pillar guide-localization effect that utilizes to be provided, make the mould twice-die-opening, and the material handle separates with product smoothly, and product stripping is easy to injection mold guide pillar order stripping mechanism.
The technical scheme of the utility model injection mold guide pillar order stripping mechanism is: comprise upper mould plate and lower bolster, cope match-plate pattern connects gate plate down, is equipped with sprue bush in the gate plate, and gate plate connects cavity plate down; Be shaped on die cavity in the cavity plate, the mould pin is installed on the lower bolster, upper plate and lower roof plate are set in the mould pin, connect push rod on the upper and lower top board; On the mould pin core fixing plate is installed, mount type central layer on the core fixing plate is shaped on core on the core plate, the product of moulding is arranged between core and the die cavity; Leave the material handle between product and the gate plate, on the described core plate scraping wings is set, the end face of scraping wings contacts with product; Push rod passes core plate and connects scraping wings, and the core guide pillar is installed on core plate, and the core guide pillar passes core plate, scraping wings and cavity plate; Stretch in the gate plate, the die cavity guide pillar is installed in gate plate, the die cavity guide pillar passes gate plate, cavity plate and scraping wings; Stretch in the core plate, it is characterized in that being shaped on arc groove on the described core guide pillar, be shaped on the spacing groove on the die cavity guide pillar; In a side of cavity plate, arced marble is set, arced marble has the compression spring, and is fixed by plug; Arced marble matches with arc groove, and the spacing pin is installed in the opposite side of cavity plate, and the spacing pin matches with the spacing groove.
The injection mold guide pillar order stripping mechanism of the utility model, during injection moulding, arced marble is embedded in the arc groove; After injection mo(u)lding, injection machine power drives the core plate die sinking and moves downward, and the core guide pillar is motion and then; But owing to arced marble is embedded in the arc groove of core guide pillar, and arced marble is arranged in the cavity plate; Therefore, cavity plate follows core plate to move downward together, and cavity plate is separated with gate plate; Material handle and product in the gate plate are broken off, and the material handle is stayed in the gate plate, will expect that by manual work or manipulator handle takes out.After cavity plate followed core plate to move to certain distance, the spacing pin in the cavity plate opposite side contacted with the spacing groove lower wall on the die cavity guide pillar, and the spacing pin is stuck in the spacing groove of die cavity guide pillar; Make cavity plate stop to move downward, but core plate continues to move downward, make the compression spring of arced marble force to contract in the pressurized; Arced marble and arc groove disengage; Core plate moves downward with cavity plate separates, and product is deviate to stay on the core from die cavity, drives push rod by upper and lower top board at last; Push rod promotes scraping wings product is released outside the mould, and the demoulding is accomplished.This programme utilizes the effect of guide pillar guide-localization, makes the mould twice-die-opening, will expect that handle breaks from product, makes product stay on the core to deviate from smoothly, and is simple in structure, and action is stable, reliable, easy for installation, and cost is economized.
