Description
Technical field
The present invention relates to a kind of injection mold drag hook order stripping mechanism, belong 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 objective of the invention is in order to overcome the shortcoming of prior art, a kind of drag hook lever principle of utilizing is provided, make the mould twice-die-opening, product breaks away from material handle and die cavity smoothly, and the demoulding is easy to injection mold drag hook order stripping mechanism.
The technical scheme of injection mold drag hook order stripping of the present invention mechanism is: comprise upper mould plate and lower bolster, cope match-plate pattern connects gate plate 1 time, 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; Mount type central layer on the mould pin 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, it is characterized in that a piece is installed on described cavity plate one sidewall, and a piece connects lever through pin; Last one of lever is shaped on protruding rail, and next head of lever is shaped on drag hook, on a sidewall of gate plate, roller is installed; On one sidewall of core plate fixture block is installed, roller matches with protruding rail, and fixture block matches with drag hook.
The invention discloses a kind of injection mold drag hook order stripping mechanism, during injection moulding, drag hook is held fixture block; During the demoulding, injection machine power drives core plate and the cavity plate die sinking moves downward, still; Because drag hook has been held fixture block, makes cavity plate follow core plate to move downwards, cavity plate is separated with gate plate; Material handle and product 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 ran down to certain distance, one protruding rail under effect, drove the lever perk at roller on the lever; Next drag hook and fixture block of lever disengaged, and core plate continues die sinking, separates with cavity plate; Product is deviate to stay on the core from die cavity; Drive 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 adopts the drag hook lever construction, makes the mould twice-die-opening, and product and material handle are broken, and makes product stay on the core to deviate from smoothly, and simple in structure, action is stable, reliable, easy for installation, and cost is economized.
Injection mold drag hook order stripping of the present invention mechanism is equipped with tension spring on one sidewall of described cavity plate, and tension spring connects lever, and tension spring is held lever, and next drag hook and fixture block of lever do not come off.Be shaped on locating slot in the described cavity plate, distance screws is arranged in the locating slot, distance screws connects gate plate, and distance screws plays spacing and guide effect to die cavity.
Description of drawings
Fig. 1 is an injection mold drag hook order stripping mechanism structure sketch map of the present invention.
The specific embodiment
The present invention relates to a kind of injection mold drag hook order stripping mechanism, as shown in Figure 1, comprise upper mould plate 1 and lower bolster 2, cope match-plate pattern connects gate plate 31 time; Be equipped with sprue bush 4 in the gate plate, gate plate connects cavity plate 53 times, is shaped on die cavity 12 in the cavity plate 5; Mould pin 6 is installed on the lower bolster 2, upper plate 7 and lower roof plate 8 are set in the mould pin, connect push rod 9 on the upper and lower top board; Mount type central layer 10 on the mould pin 6 is shaped on core 11 on the core plate 10, the product 13 of moulding is arranged between core 11 and the die cavity 12; Leave material handle 14 between product 13 and the gate plate 3, on the described core plate 10 scraping wings 15 is set, the end face of scraping wings 15 contacts with product 13; Push rod 9 passes core plate 10 and connects scraping wings 15, it is characterized in that installing on described cavity plate 5 one sidewalls piece 16, and a piece 16 connects lever 18 through pin 17; Last one of lever 18 is shaped on protruding rail 19, and next head of lever 18 is shaped on drag hook 20, and roller 21 is installed on a sidewall of gate plate 3; Fixture block 22 is installed on one sidewall of core plate 10, and roller 21 matches with protruding rail 19, and fixture block 22 matches with drag hook 20.During injection moulding, drag hook 20 is held fixture block 22, during the demoulding; Injection machine power drives core plate 10 and moves downward with cavity plate 5 die sinkings, still, because drag hook 20 has been held fixture block 22; Make cavity plate 5 follow core plate 10 to move downwards, cavity plate 5 is separated with gate plate 3, and material handle 14 and product 13 are broken off; Material handle 14 is stayed in the gate plate 3, will expect that by manual work or manipulator handle takes out.After cavity plate 5 ran down to certain distance, one protruding rail 19 under effect, drove lever 18 perks at roller 21 on the lever 18; Next drag hook 20 of lever 18 is disengaged with fixture block 22, and core plate 10 continues die sinkings, separates with cavity plate 5; Product 13 is deviate to stay on the core 11 from die cavity 12; Drive push rod 9 by upper and lower top board 7,8 at last, push rod 9 promotes scraping wings 15 product 13 is released outside the mould, and the demoulding is accomplished.This programme adopts the drag hook lever construction, makes the mould twice-die-opening, and product and material handle are broken, and makes product stay on the core to deviate from smoothly, and simple in structure, action is stable, reliable, easy for installation, and cost is economized.Be equipped with tension spring 23 on one sidewall of described cavity plate 10, tension spring 23 connects levers 18, and tension spring is held lever, and next drag hook and fixture block of lever do not come off.Be shaped on locating slot 24 in the described cavity plate 5, distance screws 24 is arranged in the locating slot 24, distance screws 25 connects gate plate 3, and distance screws plays spacing and guide effect to die cavity.
