Description

Injection mold sequential slider mould emptier
Technical field
The utility model relates to a kind of injection mold sequential slider mould emptier, 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 employing slide block drag hook form to be provided, make the mould twice-die-opening, and product breaks away from the material handle smoothly, and the demoulding is easy to injection mold sequential slider mould emptier.
The technical scheme of the utility model injection mold sequential slider mould emptier 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, mount type central layer on the mould pin is shaped on core on the core plate; The product that moulding is arranged between core and the die cavity leaves 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, and push rod passes core plate and connects scraping wings, it is characterized in that in the sidewall of said cavity plate slide block being set; The compression spring is arranged in the slide block, and the end face of slide block is the plane, the bottom surface head bevel of slide block; On a sidewall of core plate, pull bar is installed, rod head is shaped on drag hook, and drag hook contacts with the end face of slide block; On a sidewall of gate plate, depression bar is installed, the head of depression bar is shaped on briquetting, and briquetting contacts with the inclined-plane of slide block bottom surface.
The injection mold sequential slider mould emptier of the utility model, during injection moulding, drag hook blocks slide block; During the demoulding, injection machine power drives core plate and the cavity plate die sinking moves downward, still; Because drag hook has blocked slide block, makes cavity plate follow core plate to move downwards, and cavity plate is separated with gate plate; Thereby 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, briquetting contacted with the inclined-plane of slide block bottom surface, and slide block is inwardly pressed; The compression spring shrinks, and the inside indentation of slide block disengages with drag hook; Core plate continues die sinking, separates with cavity plate, and 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 slide block drag hook form, 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.
The injection mold sequential slider mould emptier of the utility model is shaped on locating slot in the described cavity plate, and dog screw is arranged in the locating slot, and dog screw connects gate plate, and dog screw plays the role of positioning to die cavity, prevents that the die cavity die sinking is excessive.Be shaped on stopper slot on the described slide block, be equipped with spacer pin in the cavity plate, spacer pin matches with stopper slot, and spacer pin plays position-limiting action to slide block, and anti-limited slip block is compressed spring and ejects too much, and slide block comes off.
Description of drawings
Fig. 1 is the utility model injection mold sequential slider mould emptier structural representation.
The specific embodiment
The technical scheme of the utility model injection mold sequential slider mould emptier is: comprise upper mould plate 1 and lower bolster 2, cope match-plate pattern connects gate plate 31 time, is equipped with sprue bush 4 in the gate plate, and gate plate connects cavity plate 53 times; Be 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 that moulding is arranged between core 11 and the die cavity 12 leaves 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, and push rod 9 passes core plate 10 and connects scraping wings 15, it is characterized in that in the sidewall of said cavity plate 5 slide block 16 being set; Compression spring 17 is arranged in the slide block, and the end face of slide block 16 is the plane, the bottom surface head bevel 18 of slide block 16; Pull bar 19 is installed on a sidewall of core plate 10, and pull bar 19 heads are shaped on drag hook 20, and drag hook 20 contacts with the end face of slide block 16; Depression bar 21 is installed on a sidewall of gate plate 3, and the head of depression bar 21 is shaped on briquetting 22, and briquetting 22 contacts with the inclined-plane 18 of slide block 16 bottom surfaces.During injection moulding, drag hook 20 blocks slide block 16, 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 blocked slide block 16; Make cavity plate 5 follow core plate 10 to move downwards, cavity plate 5 is separated with gate plate 3, thereby 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, briquetting 22 contacted with the inclined-plane 18 of slide block 16 bottom surfaces, and slide block 16 is inwardly pressed; Compression spring 17 shrinks, and slide block 16 inside indentations disengage with drag hook 20; Core plate 10 continues die sinking, separates with cavity plate 5, and 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 slide block drag hook form, 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 shaped on locating slot 23 in the described cavity plate 5, dog screw 24 is arranged in the locating slot 23, dog screw 24 connects gate plate 3, and dog screw plays the role of positioning to die cavity, prevents that the die cavity die sinking is excessive.Be shaped on stopper slot 25 on the described slide block 16, be equipped with spacer pin 26 in the cavity plate 5, spacer pin 26 matches with stopper slot 25, and spacer pin plays position-limiting action to slide block, and anti-limited slip block is compressed spring and ejects too much, and slide block comes off.
