Abstract
The utility model discloses a kind of mouth mould of blow mold, comprise the mouth mould body of a band blank outlet, the blank outlet interior shape of described mouth mould body is circular port, and the oral area shape of blank outlet is the slotted eye close to mold cavity.Blank outlet oral area is arranged to ellipsoidal structure by the utility model, effectively can shorten the spacing of mouthful mould and die cavity, have folding mould apart from short, energy consumption is low, overlap material is few, parison periphery to be rested and reorganized feature easily to a distribution.
Description
Technical field
The present invention relates to blow mold, be specially a kind of mouth mould of blow mold.
Background technology
In blow mold, for realizing the blowing processing of product, need by mouth mould toward die cavity injected plastic, but at present, the whole blank outlet of tradition mouth mould is all circular configuration, this vibrational power flow is little for little and equilateral Product processing problem, but large-scale for those and that the Product processing that length and width are inconsistent existence is very large problem.
Because the length variation of the shape of the mouth as one speaks bore of blank outlet and product is too large, for plastics can be made fully fully to fill die cavity, the spacing between mouth mould and chamber shape must widen, and ensures that plastics enter and possess the enough expansion time with this.And this can increase the folding mould distance of mould on the one hand greatly, increase manufacture and the operating cost of equipment.Simultaneously after product blowing completes, the overlap material of one section very long can be produced between mouth mould and die cavity, not only cause a large amount of pre-thermal energy consumption wastes, and this part overlap material directly cannot reclaim use, must carry out being separated, reclaim, utilize after pulverization process, cause the very large wasting of resources.
The shape of the circular blank outlet of this external cause and the shape difference of product too large, not only shaped article is single, simultaneously because mould distribution that work in-process mouth mould is corresponding will find the angle of corresponding points, and the precision of this angle is difficult to hold, easily by the air pressure of parison during matched moulds and the impact of air-capacitor size, the thick distribution to mold cavity of mouthful type of mould distributed points can not ideal distribution be put in place, and the wall thickness control adjustment of product is more difficult.
Summary of the invention
For the problems referred to above, the present invention devises a kind of mouth mould of blow mold, its blank outlet oral area adopts ellipsoidal structure, effectively can shorten the spacing of mouthful mould and die cavity, have folding mould apart from short, energy consumption is low, overlap material is few, parison periphery to be rested and reorganized feature easily to a distribution.
For achieving the above object, the present invention is by the following technical solutions:
A mouth mould for blow mold, comprises the mouth mould body of a band blank outlet, it is characterized in that: the blank outlet interior shape of described mouth mould body is circular port, and the oral area shape of blank outlet is the slotted eye close to mold cavity.
Further, be connected by transition circle cambered surface between the inner circular hole of above-mentioned blank outlet and the slotted eye of blank outlet oral area.
Further, above-mentioned blank outlet oral area is the slotted eye being at least two steps, and the aperture of each step slotted eye sequentially increases.
Further, connected by tapered slope between adjacent step slotted eye.
The oral area shape of mouth mould blank outlet of the present invention adopts the oval-shaped pore structures on multiple stage rank, cavity shape is similar to through this blank outlet ejection shape out, not only corresponding mouth mould abnormity is repaired thickness gain and can be reached most perfect condition, and only need shorter folding mould distance to carry out blowing processing, the distance with folding mould is short, the manufacture of equipment and the low feature of operating cost, effectively can reduce the overlap material mouthful between mould and die cavity simultaneously, reduce pre-thermal energy consumption and unnecessary wastage of material.
Accompanying drawing explanation
Fig. 1, perspective view of the present invention.
Detailed description of the invention
A kind of mouth mould of blow mold, comprise the mouth mould body 1 of a band blank outlet, blank outlet 11 interior shape of mouth mould body 1 is circular port 111, the oral area shape of blank outlet 1 is the slotted eye 112 close to mold cavity, and is connected by transition circle cambered surface 1111 between the inner circular hole 111 of blank outlet 11 and the slotted eye 112 of blank outlet oral area.
The oral area shape of above blank outlet 11 adopts slotted eye 112 structure, make to be similar to cavity shape through this blank outlet 11 ejection shape out, not only the abnormity of corresponding mouth mould is repaired thickness gain and can be reached most perfect condition, the polygon abnormity of product not uniform thickness can be repaiied, product periphery is rested and reorganized to a distribution convenient, conveniently control adjustment is carried out to the wall thickness of product.
In addition, oval blank outlet 11 oral area, effectively can increase the molar of mould, and only need a shorter folding mould distance can meet blowing processing, the distance with folding mould is short, the manufacture of equipment and the low feature of operating cost.
Simultaneously, oval blank outlet oral area is arranged, and effectively can shorten the distance mouthful between mould and die cavity, also effectively can reduce mouthful overlap material produced between mould and die cavity, comparing existing wholecircle shape vibrational power flow can reduce over half, effectively can reduce pre-thermal energy consumption and unnecessary wastage of material.
In practice, for promoting the processing effect of mouthful mould further, blank outlet 11 oral area of described mouth mould body 1 is the slotted eye 112 being at least two steps, and the aperture of each step slotted eye 112 sequentially increases, what adopt in the present embodiment is exactly two steps, can adopt more than three steps or three steps in practice as required.Connected by tapered slope 1121 between described adjacent step slotted eye 112.Slotted eye 112 vibrational power flow on above multiple stage rank, make plastics from blank outlet 11 out after expand gradually, to meet the needs of large volume length and width inequilateral Product processing.
The above, it is only better embodiment of the present invention, not any pro forma restriction is done to the present invention, every according to know-why of the present invention to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solution of the present invention.
