Abstract
The invention provides a vacuum forming mold for a plastic corrugated pipe, and belongs to the field of plastic extrusion forming equipment. The vacuum forming mold structurally comprises a mold body, wherein one to two racks are machined on the outer side of the mold body; more than one semicircular groove with a corrugated pattern is formed in the mold body; a slot in the direction consistent with the concave convex direction of the corrugated pattern is axially formed at the corrugated pattern of each semicircular groove; the slot is communicated with an air suction hole in the mold body. In addition, the mold body can also be made of a breathable steel material, so that no micro-pore or slot and air suction hole are required to be formed. The forming mold is low in cost, and the equipment cost is also low and is lower than half of the original price; after the equipment cost is reduced, the cost of the plastic corrugated pipe is also reduced, particularly for the corrugated pipes such as drainage pipes of Haier washing machines which cannot be machined by using an internal air pressure method; conventional drainage pipes are basically finished by using a manual opening mold, so that the labor intensity of workers is high, only the single-piece production can be realized, but the continuous production cannot be realized; the pipes are produced by using the mold at present, so that the quality and the efficiency are greatly improved.
Description
(1) technical field
The present invention relates to a kind of plastic extruding forming equipment, specifically a kind of plastic film capicitor vacuum forming mould.
(2) background technology
Plastic film capicitor is a kind of flexible pipe, is mainly used in trunking, washing machine sewer pipe (caliber difference in change is not less than 20%), lung ventilator tracheae etc.Plastic extruder and corrugated pipe forming machine are the special equipments of producing continuously plastic film capicitor, and product specification size realizes by changing different size mould.
Plastic film capicitor has two kinds of forming methods always, and a kind of is interior platen press (have gas to block up, with compressed air, pipe embryo is propelled the price of to moulding in mould); A kind of is to inhale vacuum method (mould has some micropores that the air sucking-off outside pipe embryo and between in mould is made to its moulding from the inside to the outside).
It is stifled that interior platen press need to be laid gas in pipe embryo, and manage embryo in mould, and this needs the stifled external diameter of gas to coordinate the effective gas shutoff of just right guarantee not affect again the movement of bellows and mould with pipe embryo internal diameter.This requires higher for the stifled profile of gas, dimensional accuracy, roughness, it is very big that operating personnel guarantee mould, pipe embryo in invisible situation, gas blocks up the concentric difficulty of three, the operative employee that has a strong sense of responsibility that need to have wide experience, because of carelessness easy mold damage also.
Inhale vacuum method and be and process some micropores inhaling on vacuum mold, because the aperture of micropore is between 0.5-0.7 millimeter, so difficulty of processing is large, mould is very expensive, also more expensive than equipment.
Two kinds of methods are in use procedure for many years, and vacuum method is obviously better than the first, and bellows that vacuum method is produced is wide in variety and quality good, and simple to operate, yield rate improves greatly.Platen press is not produced and inhales vacuum method and can produce in some bellows, such as the drainpipe of Haier's washing machine etc.But vacuum method mould processing technology component difficulty is large, Die price is very high, and general user is reluctant to buy, now most of use on market or interior platen press.
(3) summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, provides a kind of processing method to simplify, and has reduced the plastic film capicitor vacuum forming mould of manufacture difficulty and processing cost.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of plastic film capicitor vacuum forming mould, comprise die ontology, die ontology outside is processed with one to two toothed rack, in die ontology, offer the more than one semi-circular groove with ripple, the ripple place of described semi-circular groove offers the finedraw consistent with ripple concave and convex direction vertically, and finedraw is connected with the suction hole in being opened in die ontology.
The quantity of the semi-circular groove on described die ontology is two, and diameter is different.
The width of described finedraw is 0.2-0.3 millimeter, and the degree of depth is 3-10 millimeter.
The aperture of described suction hole is 6-8 millimeter.
Described finedraw is opened on the non-cooperation contact-making surface of die ontology, also can be opened on the cooperation contact-making surface of die ontology.During use, two die ontologies are used in conjunction with, and semi-circular groove forms a through-hole structure completing.Be that finedraw also can mating surface place, also can be or not mating surface place.
A kind of plastic film capicitor vacuum forming mould, comprise die ontology, die ontology outside is processed with one to two toothed rack, offers the more than one semi-circular groove with ripple in die ontology, and its innovative point is that described die ontology adopts ventilative Steel material to be made.
Compared with prior art, the beneficial effect producing is a kind of plastic film capicitor vacuum forming mould of the present invention:
The present invention is mainly that die cost is low compared with the prior art, the price of equipment is also low, less than half, after equipment price is low, the price of plastic film capicitor also can reduce, especially the bellows that interior platen press is not processed is as the drainpipe of Haier's washing machine, existing drainpipe substantially by hand opening mold completes, and workman's labour intensity is large, can only single-piece production can not produce continuously, just used now this mould instead and produced, quality and efficiency improve greatly.
