Abstract

A water bucket cap inner cap mould secondary compulsive demoulding mechanism comprises an upper doubling plate and a lower doubling plate. The upper doubling plate is connected with a fixed mould doubling plate and a fixed mould plate in which a fixed mould insert is arranged. The lower doubling plate is provided with a support block in which a top plate is arranged. The top plate is connected with a top lever. The support block is provided with a moving mould doubling plate and a moving mould plate in which a moving mold insert is arranged. The utility model is characterized in that a stripper plate is arranged between the fixed mould plate and the moving mould plate, and an ejection spring and a limit bolt are arranged between the moving mould plate and the stripper plate. The inverse opening insert of an inner cap is arranged in the moving mould insert, the snap ring insert of the inner cap is arranged in the stripper plate, and the fixed mould insert, the inverse opening insert and the snap ring insert fit and form a mould cavity. The molded inner cap is arranged in the mould cavity. The top lever passes through the inverse opening insert and contacts with the inner cap. The scheme ejects out the inner cap in two times. In the ejection process, the snap ring or the inverse opening of the inner cover can not be damaged easily, the rejection rate of products is reduced, the cost is saved, the internal configuration of the mould is simplified and the mould investment is saved.

Description

The strong off line structure of scuttlebutt bottle cap inner cap mould secondary

Technical field

The utility model relates to the strong off line structure of scuttlebutt bottle cap inner cap mould secondary, belongs to the mould of plastics field.

Background technology

In order to install reliable and convenient, be shaped on snap ring on the outer wall top of scuttlebutt bottle cap inner cap, the inwall oral area of inner cap is shaped on down mouthful, and needing that after injection mo(u)lding snap ring and the mouth that falls are carried out the demoulding could eject inner cap.The angled-lift splits and the angle ejector rod demoulding are adopted in the snap ring of prior art inner cap and mouthful demoulding of falling, and the shortcoming of its existence is to cause the mould inside complex structure, increase the mould investment.Another kind method is to adopt direct forced stripper mechanism, and when injection mo(u)lding, inner cap is also softer, directly inner cap is ejected, but because the snap ring of inner cap and fall mouthful all also to be stuck in the mould, often eject the snap ring of inner cap simultaneously or to fall mouthful top bad, product percent defective height.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of employing secondary forced stripper mechanism mode to be provided, both simplified the mould inside structure, guaranteeing the strong off line structure of scuttlebutt bottle cap inner cap mould secondary of product quality again.

The technical scheme of the strong off line structure of the utility model scuttlebutt bottle cap inner cap mould secondary is: comprise compound plate and following compound plate, last compound plate connects cover half compound plate and solid plate, fixed die insert is installed in the solid plate, the mould pin is installed on the following compound plate, in the mould pin top board is set, top board connects push rod, dynamic model compound plate and moving platen are installed on the mould pin, moving die insert is installed in the moving platen, it is characterized in that between described solid plate and the moving platen stripper plate being installed, be equipped with ejector spring and stop screw between moving platen and the stripper plate, the mouth that falls of inner cap is installed in moving die insert is inserted, the snap ring of inner cap is installed in the stripper plate is inserted fixed die insert, cooperate between the mouth that falls is inserted and snap ring is inserted and constitute die cavity, the inner cap that moulding is arranged in the die cavity, push rod pass down mouth and insert and contact with inner cap.

The strong off line structure of scuttlebutt bottle cap inner cap mould secondary of the present utility model, during the demoulding, at first drive the solid plate die sinking by injection machine power, owing to be equipped with ejector spring between moving platen and stripper plate, after the solid plate die sinking, the clamp force of moving platen and stripper plate disappears, under the power effect of the top of ejector spring, ejector spring follows solid plate to go up the top simultaneously stripper plate, and the snap ring in the stripper plate is inserted and fallen the mouth middle forced stripper mechanism of inserting with inner cap from moving platen, finishes forced stripper mechanism for the first time; Owing between moving platen and stripper plate, be equipped with stop screw, under the position-limiting action of stop screw, ejector spring no longer goes up the top after stripper plate is pushed up certain stroke, and solid plate continues die sinking, solid plate separates with stripper plate, by injection machine power drive top board and push rod inner cap is ejected from snap ring is inserted at last, forced stripper mechanism is finished for the second time.This programme is divided into twice pressure with inner cap and ejects, and the snap ring of inner cap or the mouth that falls are not fragile when ejecting, and reduces the percent defective of product, saves cost, simplifies the mould inside structure simultaneously, the mould reduced investment.

The specific embodiment

The utility model relates to the strong off line structure of a kind of scuttlebutt bottle cap inner cap mould secondary, as shown in Figure 1-Figure 3, comprise compound plate 1 and following compound plate 2, last compound plate connects cover half compound plate 3 and solid plate 4, fixed die insert 5 is installed in the solid plate 4, mould pin 6 is installed on the following compound plate 2, top board 7 is set in the mould pin, top board connects push rod 8, dynamic model compound plate 9 and moving platen 10 are installed on the mould pin, moving die insert 11 is installed in the moving platen 10, it is characterized in that installing between described solid plate 4 and the moving platen 10 stripper plate 12, be equipped with ejector spring 14 and stop screw 13 between moving platen 10 and the stripper plate 12, the mouth that falls of inner cap is installed in moving die insert 11 is inserted 16, the snap ring of inner cap is installed in the stripper plate 12 is inserted 15, fixed die insert 5, the mouth that falls insert 16 and snap ring insert to cooperate between 15 and constitute die cavity, the inner cap 17 that moulding is arranged in the die cavity, push rod 8 pass down mouth and insert and 16 contact with inner cap 17.During the demoulding, at first drive solid plate 4 die sinkings by injection machine power, owing between moving platen 10 and stripper plate 12, be equipped with ejector spring 14, after solid plate 4 die sinkings, the clamp force of moving platen 10 and stripper plate 12 disappears, and under the power effect of the top of ejector spring 14, ejector spring 14 follows solid plate 4 to go up the top simultaneously stripper plate 12, snap ring in the stripper plate 12 is inserted and 15 is fallen the mouth forced stripper mechanism in 16 of inserting with inner cap 17 from moving platen 10, finishes forced stripper mechanism for the first time; Owing between moving platen 10 and stripper plate 12, be equipped with stop screw 13, under the position-limiting action of stop screw 13, ejector spring 14 no longer goes up the top after stripper plate 12 is pushed up certain stroke, and solid plate 4 continues die sinking, solid plate 4 separates with stripper plate 12, drive top board 7 and push rod 8 by injection machine power at last and inner cap 17 is inserted from snap ring ejected 15, forced stripper mechanism is finished for the second time.This programme is divided into twice pressure with inner cap and ejects, and the snap ring of inner cap or the mouth that falls are not fragile when ejecting, and reduces the percent defective of product, saves cost, simplifies the mould inside structure simultaneously, the mould reduced investment.
