Abstract
The utility model is related to injection mold technology, more particularly to a kind of ejecting mechanism of large mold.It includes moving platen, ejection cylinder, liftout plate, liftout plate guide rod, the ejection cylinder is arranged on the back of moving platen, the ejection plate level is slided arranged on the forepart of moving platen, the piston rod of ejection cylinder is drivingly connected with liftout plate, the liftout plate is in H-type, and horizontal mandril is both provided on each end of the liftout plate.The liftout plate of the utility model is in H-type, and it is both provided with horizontal mandril on each end of liftout plate, compared to the ejecting mechanism of traditional moulds, spacing between the left and right two horizontal mandrils of the utility model is remote, the uniform force that mould inside top is pulled, so that die life is longer, mould inside top is not easy to wander off when pulling movement, so as to be conducive to eject product, the utility model is suitable for large mold.
Description
Technical field
The utility model is related to injection mold technology, more particularly to a kind of ejecting mechanism of large mold.
Background technology
As market competition is increasing, domestic and international PET bottle embryo requires a multi-cavity mold more and more, and chamber number wants modulus
Tool is bigger.In order to which client is helped to create the profit of bigger, big mold is proposed（Slender type）The imagination being attached on minicomputer, passes through
In energy consumption, machine price client is helped to save cost, so as to create the profit of bigger.Realize that big mold is attached to minicomputer
On, machine ejecting structure will the structure of mating mold make optimization design.The ejecting structure of traditional large mold such as Fig. 1 institutes
Show：Ejection cylinder 2 by screw be mounted on moving platen 1 on, liftout plate 3 by liftout plate guide rod 2 installation with moving platen 1 inside,
Liftout plate 3 is connected with ejection cylinder 2, and liftout plate 3 is promoted when ejection cylinder 2 acts, and is ejected bottle embryo by mould inside structure, is passed
The liftout plate 3 of system is in crosswise, between two horizontal mandrils are horizontally spaced about between one end of liftout plate, two horizontal mandrils
Short away from d2, two horizontal mandrils excessively concentrate the power that mould inside top is pulled, and the stress that mould inside top is pulled is bad, if mold compared with
Ejection that is big then being unfavorable for product.And two horizontal mandril be horizontally spaced about in one end of liftout plate, left and right two horizontal mandril
The distance between adjustable scope（d1）It is small, designer can not according to the size of mold, adjust left and right two horizontal mandril it
Between distance, so as to can not meet the needs of different molds.
Utility model content
The purpose of this utility model is to provide one kind is reasonable in design, left and right two horizontal mandril is distant, thrust
Uniformly, be conducive to eject the ejecting mechanism of the large mold of product.
What the purpose of this utility model was realized in：
A kind of ejecting mechanism of large mold, including moving platen, ejection cylinder, liftout plate, liftout plate guide rod, the ejection
Oil cylinder is arranged on the back of moving platen, and the ejection plate level is slided arranged on the forepart of moving platen, the piston rod of ejection cylinder and top
Ejecting plate is drivingly connected, which is characterized in that the liftout plate is in H-type, and horizontal top is both provided on each end of the liftout plate
Bar.
The utility model can also improve further below.
The liftout plate is equipped with liftout plate guide rod, and liftout plate is slided by the way that liftout plate guide rod is horizontal before moving platen
Portion.
Paired horizontal mandril is provided in the middle part of the liftout plate.
The ejection cylinder is fixed on by bolt, nut on moving platen.
More horizontal mandrils on the liftout plate are arranged in pairs.
The beneficial effects of the utility model are as follows：
（One）The liftout plate of the utility model is in H-type, and horizontal mandril is both provided on each end of liftout plate, is compared
The ejecting mechanism of traditional moulds, the spacing between the left and right two horizontal mandrils of the utility model is remote, the stress that mould inside top is pulled
Uniformly, so that die life is longer, mould inside top is not easy to wander off when pulling movement, so as to be conducive to ejection system
Product, the utility model are suitable for large mold.
（Two）In addition, compared to the adjustable scope of the distance between the ejecting mechanism of traditional moulds, left and right two horizontal mandril
Greatly, designer can adjust the distance between left and right two horizontal mandril, so as to meet different molds according to the size of mold
Demand.
Description of the drawings
Fig. 1 is the structure diagram of the ejecting mechanism of existing mold.
Fig. 2 is the structure diagram of the ejecting mechanism of the utility model large mold.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Embodiment one, as shown in Fig. 2, a kind of ejecting mechanism of large mold, including moving platen 1, ejection cylinder 2, ejection
Plate 3,3 guide rod of liftout plate, the ejection cylinder 2 are arranged on the back of moving platen 1, and horizontal slide of the liftout plate 3 is arranged on moving platen 1
Forepart, piston rod and the liftout plate 3 of ejection cylinder 2 be drivingly connected, and the liftout plate 3 is in H-type, the liftout plate 3 it is each
Horizontal mandril 4 is both provided on end.
The more specific technical solution of the utility model.
The liftout plate 3 is equipped with liftout plate guide rod 5, and liftout plate 3 is arranged on moving platen by horizontal slide of liftout plate guide rod 5
1 forepart.
The middle part of the liftout plate 3 is provided with paired horizontal mandril 4.
The ejection cylinder 2 is fixed on by bolt, nut on moving platen 1.
