Abstract
The utility model provides an air cushion one shot forming die geometry belongs to blowing mould field, it has solved the problem that present blowing mould die geometry can not once produce the air cushion. The utility model discloses an annular outer die with establish the inboard interior bush at outer die, form the ring shape cavity runner that the wall thickness is the same between outer die and the interior bush, still be equipped with the mandrel that a plurality of longshore currents said that the annular distributed between outer die and the interior bush, and form the space between adjacent mandrel and mandrel and adjacent outer die and the interior bush, the last lug that is equipped with of outer die is equipped with the recess on the interior bush, and the lug coordinates and places in the recess to form the breach on the runner. Can form hollow material embryo through the cavity runner, the material embryo forms on the space air cushion that the gas pocket was taken in formation between adjacent mandrel and mandrel and adjacent outer die and interior bush, and there is not the material embryo in the while air cushion with the breach position that the runner corresponds for final fashioned air cushion is the sheet structure, avoids the secondary cutting.
Description
Technical field
The utility model belongs to blow mold technical field, relates to a kind of air cushion one-shot forming die geometry.
Background technology
Adopt air cushion prepared by plastic sheeting, when not inflating, floor space is little, and transport storage is very convenient, and recovery is convenient, does not pollute the environment.But the film blow mold of great majority production air-cushion film through simple refit in traditional moulds, needs secondary cut in production process, also needs to purchase special cutting tool, make production process increase.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of air cushion one-shot forming die geometry of energy one-shot forming air cushion.
The purpose of this utility model realizes by following technical proposal: a kind of air cushion one-shot forming die geometry, comprise annular outer mouth mould and be located at the internal orifice mould inside collar extension mould, the annular hollow duct that wall thickness is identical is formed between described collar extension mould and internal orifice mould, it is characterized in that: between described collar extension mould and internal orifice mould, be also provided with some cores along runner annular spread, and adjacent core and core and form space between adjacent collar extension mould and internal orifice mould, described collar extension mould is provided with projection, internal orifice mould is provided with groove, and described projection cooperation is placed in described groove, and breach is formed on described runner.
Hollow material embryo can be formed by hollow duct, material embryo is at adjacent core and core and form air cushion space being formed and is with pore between adjacent collar extension mould and internal orifice mould, there is not material embryo in the gap position that air cushion is corresponding with runner simultaneously, the air cushion making final molding is laminated structure, avoids secondary cut.
As preferably, projection both sides and internal orifice mold shaft line parallel.
Therefore the air cushion produced is square structure in tiling afterwards, can be suitable for multiple occasion.
As preferably, projection end has locating piece, and described internal orifice mould is provided with the locating slot be connected with groove, and when forming the identical runner of wall thickness between described collar extension mould and internal orifice mould, described locating piece overall co-ordination is placed in locating slot.
Therefore coordinate by locating piece and locating slot the effect playing location internal orifice mould and collar extension mould.
As preferably, described core on runner in rectangular flat arcuate structure.
Therefore the air cushion produced can pour more gas.
As preferably, described locating piece and locating slot rounded.
As preferably, described internal orifice mold shaft is provided with passage in the heart.
Compared with prior art, the utility model tool has the following advantages:
Hollow material embryo can be formed by hollow duct, material embryo is at adjacent core and core and form air cushion space being formed and is with pore between adjacent collar extension mould and internal orifice mould, there is not material embryo in the gap position that air cushion is corresponding with runner simultaneously, the air cushion making final molding is laminated structure, avoids secondary cut.
