Description
Technical field
The utility model relates to a kind of injection mold centering block drawplate type secondary mould emptier, belongs to the mould of plastics field.
Background technology
At present, adopt mould of plastics to produce similar round plastic spare, for example lid etc. is shaped on bulge loop or bead on the bottom surface of this series products or the outer wall, when traditional moulds is produced this series products, all is to adopt direct push rod top and stripper plate to unite to eject.But behind the working of plastics ejection device, but be stuck on the stripper plate, working of plastics can not come off automatically, also needs manual work to take off.Such mould emptier when die production, is not only lost time, and also can increase operative employee's labour intensity.And working of plastics is easy to generate distortion, breakage, causes working of plastics to scrap.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art; A kind of employing swing arm-tie form is provided, drives stripper plate jack-up, thereby realize that the push rod secondary ejects; Make the product demoulding smoothly; Realize automated production, and guarantee that working of plastics is indeformable, the measured injection mold centering block of matter drawplate type secondary mould emptier.
The technical scheme of the utility model injection mold centering block drawplate type secondary mould emptier is: comprise mold cavity plate and core plate, core is installed in the core plate is inserted, be equipped with stripper plate outside core is inserted; Stripper plate, core insert and cavity plate between the product of moulding is arranged, the bottom surface of product is shaped on convex tendon, described core plate and core are inserted and are installed on the core fixing plate; Core fixing plate is installed on the mould pin, and the mould underfooting is equipped with lower bolster, and upper plate and lower roof plate are set between the mould pin; Connect push rod on the upper plate, push rod passes core fixing plate and core and inserts and contact with the product bottom surface, it is characterized in that on the described cavity plate two side arm-tie being installed respectively; The head of arm-tie is shaped on inclined-plane and projection, is shaped on breach on the two side of described core plate respectively, and centering block is installed in the breach; The head of centering block is connected by extension spring, and the head of centering block is processed arc surface, and stretches out outside the breach; Contact with the inclined-plane during die sinking, contact with the stripper plate bottom surface after the die sinking.
The injection mold centering block drawplate type secondary mould emptier of the utility model, during the demoulding, at first mould die sinking; Core is inserted, stripper plate separates with cavity plate, product stay core insert with stripper plate on, continue die sinking; Inclined-plane on the arm-tie contacts with the arc surface of centering block head, and centering block is inwardly swung, and the arc surface of centering block contacts with the bottom surface of stripper plate; Drive centering block with stripper plate jack-up, stripper plate drive product is inserted with core and is separated, and continues die sinking again; Upper and lower top board contacts with the ejecting mechanism of injection machine, and the push rod that the injection machine ejecting mechanism promotes on the upper and lower top board ejects product outside the stripper plate, and product is deviate from from mould.During matched moulds, push rod resets, and product comes off.This programme adopts arm-tie to drive centering block swing form, makes stripper plate jack-up product, and the push rod secondary ejects again, and product is ejected outside the stripper plate, has realized that secondary ejects, and makes product stripping smooth, and indeformable, quality is good.
The injection mold centering block drawplate type secondary mould emptier of the utility model, described core plate outer wall is equipped with limitting casing, and the inwall of limitting casing contacts with the outer wall of arm-tie, and arm-tie is played position-limiting action, prevents the arm-tie distortion.Be shaped on stopper slot in the described core plate, be equipped with distance screws in the stopper slot, distance screws connects stripper plate, and distance screws has ejected position-limiting action to stripper plate, prevents to eject excessive.
