Abstract
The utility model discloses a mould for making polyester bottle base with arc type hot runner, comprising a base plate, a cold water pipe, a fixed shape core plate, a mould core, a mould cavity, a hot runner, a fixed plate, a middle plate, a clamp plate, a holding ring, etc. The maximum mould gradient can be achieved by adjusting the conditions of the injection rubber pipe, the injection pressure, the injection velocity, the cooling time, etc. of the injection mould machine to make one mould provide with four cavities, six cavities or even more. The mould has the advantages of convenient operation, saving time, saving equipment and saving human power, and is an ideal mould. The utility model is suitable for manufacturers who make polyester bottle bases.
Description
The utility model relates to a kind of improvement of mould, particularly a kind of improvement of producing a mould one cavity mould technology of polyester bottle base with two step method.
Before the utility model was made, the mould of existing production polyester bottle base was a lot.Homemade production mould majority is to produce the polyester bottle base with step two step method at present, is a mould one chamber or a mould two chambeies generally, promptly can only go out a bottle base or two bottle bases at every turn.
Problem is that this production technology effect is low, reach high yield, must increase the investment of equipment again, causes the cost height, operating difficulties, and to increase the operator again.
The purpose of this utility model will be improved this mould exactly, seeks a kind ofly can produce the qualified polyester bottle base of high yield, can save equipment investment again, labor-saving novel die.
The utility model is achieved in that entire die is made up of base plate (1), cold water pipe (2), solid core board (3), the type heart (4), die cavity (5), hot flow path (6), fixed head (7), middle plate (8), clamping plate (9), locating ring parts such as (10).Mould is installed on the injection frame, Gu core board (3) is reciprocating with the type heart (4) and die cavity (5), polyester fondant is by the injection orifice of locating ring (10), flow into hot flow path (6), colloid is injected die cavity (5) typing, cold water cools off bottle base rapidly by cold water pipe (2) the inflow type heart (4), has so just finished whole injection phase.Smooth and easy for the runner that guarantees two end in contact, the plane that hot flow path is original changes the contact of garden cambered surface into, reduces the resistance of runner, and anti-leak-stopping glue guarantees the amount of injecting of colloid, so just can a mould four chambeies, six chambeies or more.By injection glue amount, injection pressure, injection speed, the cool time of adjustment injector, and the melt temperature of adjustment polyester material, adjust chilling temperature by cooling water pipe again, produce the polyester bottle base that conforms to quality requirements and make it reach maximum shaping gradient.
The utility model is not only easy to operate and save time, province's equipment, human-saving, favorable economic benefit and social benefit are arranged, be applicable to the producer that produces the polyester bottle base.
Accompanying drawing of the present utility model is a most preferred embodiment.
Fig. 1 is the front view (main body cutaway view) of present embodiment;
Fig. 2 is the vertical view of present embodiment;
Fig. 3 is the structure chart of present embodiment hot flow path.
Description of drawings: mould is mounted on the injection moulding frame, Gu core board (3) is reciprocating with the type heart (4) and die cavity (5), polyester fondant is by the injection orifice of locating ring (10), flow into hot flow path (6) colloid is injected die cavity (5) typing, cold water cools off bottle base rapidly by cold water pipe (2) the inflow type heart (4), thereby has finished whole injection phase.
Claims (2)
1, a kind of arc form hot flow path system polyester preform mould, it is characterized in that changing the plane of hot flow path into garden cambered surface contact, reduce the resistance of runner, guarantee the amount of injecting of colloid, the melt temperature of injection glue amount, injection pressure, injection speed, cool time and polyester material by adjusting injector makes it reach maximum shaping gradient, finishes a mould four chambeies, six chambeies or more polyester bottle base.
2, mould according to claim 1 is characterized in that using the cooling of the hot flow path and the type heart.
