Description
Technical field
This utility model relates to mould cooling technology field, the cooling of a kind of PET bottle base mold lip bilayer water hole
Structure.
Background technology
At present, design at PET (polyethylene terephthalate) the preform mould die lip cooling water channel structure for quick multi-cavity
In, it is all to use the design of monolayer " eight " font.
A kind of die lip being applied to multimode cavity injection mould is disclosed at Chinese patent ZL 201120111098.X, as it is shown in figure 1,
This die lip is the hollow cylinder that two ends, middle part are provided with projection, and two ends, middle part projection is pyramidal structure；The inner headed face that die lip is hollow
Being respectively equipped with water channel in the die lip body of both sides, its water channel is double " V " type water channels.Double " V " type water channel is by plug 5,
First water channel 6 and the second water channel 11, inlet channel 7 and water outlet water channel 10, inlet opening 8 and apopore 9 form；
First water channel 6 connects with the second water channel 11, and the first water channel 6 and the second water channel 11 are positioned at the hollow inner headed face of die lip body
Two tangential directions, junction point be respectively provided on two sides with inlet channel 7 and water outlet water channel 10, inlet channel 7 and water outlet water channel
10 are connected with inlet opening 8 and apopore 9 respectively, and inlet opening 8 and apopore 9 are positioned at the inner headed face far-end that die lip is hollow,
Plug 5 is separately positioned on the first water channel 6 and two ends of the second water channel 11, the first water channel 6 and 11 liang of the second water channel
Head envelope is got up, and makes water channel can only be intake by water inlet, outlet water outlet；First water channel 6 and water outlet water channel 10, the second water
Road 11 and inlet channel 7 respectively constitute " V " type water channel, or the first water channel 6 and inlet channel 7, the second water channel 11
Respectively constitute " V " type water channel with water outlet water channel 10, therefore water channel is referred to as double " V " type water channel.
The size that generally bottle base is important all concentrates on bottleneck, and the molding of bottleneck all concentrates on die lip, due to PET molding temperature
Spending that higher molding cycle is long at about 280 DEG C, molding shrinkage is big, so the quality of the cooling of die lip directly decision bottle base bottle
The stability of mouth size.Affect at present the factor that die lip cools down and is mainly the following aspects: the Design and Machining of die lip cooling water hole,
The temperature of cooling water, the power match of cooling-water machine.General cooling water temperature all controls at 7 DEG C-10 DEG C, the apolegamy of cooling-water machine power
All pass through mould by parameters such as the power of the weight of bottle embryo, the chamber number of mould, injection machine maximum production capacity hourly and hot flow path
Tool producer specialty calculates and configures, then adds the guarantee of a safety coefficient.In the case of auxiliary equipment meets condition, cool down water
The heat that hole is the most closely taken away near the distance of product is the most, and cooling water hole is the most around the region of product, and product cooling is the most abundant,
So the Design and Machining in die lip water hole is particularly important.If adding rate of cooling not catch up with and directly affect molding cycle, reduce
Production efficiency, adds production cost.
Utility model content
The purpose of this utility model is the knot of the PET bottle base mold lip bilayer water hole cooling providing a kind of cooling effect excellent
Structure.
Concrete technical scheme of the present utility model is: the structure of a kind of PET bottle base mold lip bilayer water hole cooling, including mould
Lip, described die lip is the hollow cylinder that two ends, middle part are provided with projection, also includes two groups of symmetrically arranged cooling water channels, each
Group cooling water channel includes water inlet, outlet, is provided with and is sequentially connected with and is looped around die lip between described water inlet and outlet
Inlet opening around hollow bulb, the first lower floor water hole, the first water hole, upper strata, the second water hole, upper strata, the second lower floor water hole and water outlet
Hole, described inlet opening connects with water inlet, and described apopore connects with outlet, and described water inlet and outlet are symmetrical
It is arranged on the outside of the hollow bulb of die lip.
In the structure of above-mentioned PET bottle base mold lip bilayer water hole cooling, described the first lower floor water hole, the first upper water
The intersection in hole is provided with the first plug, and described the second water hole, upper strata, the intersection in the second lower floor water hole are provided with the second plug.
In the structure of above-mentioned PET bottle base mold lip bilayer water hole cooling, also include that slide block, described die lip are arranged on institute
On the slide block stated, described slide block is provided with the cooling water inlet pipe road connected with water inlet, described slide block is additionally provided with and goes out
The cooling water outlet pipe road of mouth of a river connection.
Compared with prior art, the beneficial effects of the utility model are:
This programme substantially increases die lip rate of cooling, it is to avoid the deformation of bottleneck size molding shrinkage causes product defective, improves
Product quality.Molding cycle improves about 2 seconds than monolayer " eight " font outlet hole structure or double V-shaped outlet hole structure, improves life
Produce efficiency, increase mould production capacity, improve economic benefit.
