Specific embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously referring to the drawings enforcement
Example is further described to the utility model.
Refering to Fig. 1 to Fig. 4, in the die casting machine of prior art, hydraulic oil cylinder driving moving platen 2 promotes left mould and right mould matched moulds, so
Afterwards in feed nozzle 10 of the injection mechanism of horizontal plunger die casting machine by molten metal by the spray of nozzle 30 to the middle part of mould 1, it is therefore desirable to
By nozzle 30 just over the ground insert feed nozzle 10 in, the feed nozzle 10 of prior art as shown in Figure 3 and Figure 4, the top of feed nozzle 10
An opening 100 is provided with, opening 100 is used to accommodate the nozzle head of nozzle 30 as shown in Figure 5.As shown in fig. 6, opening 100
Nozzle head 301 cannot completely be accommodated, have significant component of nozzle head 301 to expose, nozzle head 301 and feed nozzle 10 it
Between cooperation do not fasten, cause the nozzle 30 after coordinating to swing with respect to feed nozzle 10, technical staff is difficult accurately to judge
Whether nozzle 30 and feed nozzle 10 are to positive alignment, and the cooperation not fastened makes both there is some tiny gaps, quilt
The molten metal of high speed pressure injection easily splashes to outside, wastes production material.
Refering to Fig. 7 and Fig. 8, the utility model provides a kind of die feeding mouth structure of horizontal plunger die casting machine, wherein, including
The feed nozzle 10 at the middle part of mould 1 of die casting machine is arranged at, also includes the feed nozzle 10 is adapted to and stretched into the feed nozzle 10
Interior nozzle 30, the nozzle 30 is arranged on the injection mechanism 3 of die casting machine, and injection mechanism 3 enters molten metal by nozzle 30
It is incident upon the feed nozzle 10；
Feed nozzle 10 includes fastening part 102, and the middle part of the fastening part 102 is provided with the opening 100 for accommodating the nozzle 30,
The bottom of the fastening part 102 is provided with transition part 103, and the bottom of the transition part 103 is provided with feed nozzle main body 101, it is described enter
Material mouth 10 is hollow structure body, and the passage flowed through for molten metal is left at the middle part of feed nozzle 10.Nozzle 30 includes a nozzle master
Body 300, the bottom of the nozzle body 300 is connected with nozzle head 301, and as shown in Figure 10, be open 100 geomery and described
The geomery adaptation of nozzle head 301, so opening 100 can accommodate whole nozzle head 301, as shown in figure 9, feed nozzle 10
Opening 100 be fitted close with the nozzle head 301 of nozzle 30, now nozzle 30 can not be arbitrarily swung in the opening 100, this
Sample, technical staff can confirm that whether nozzle 30 has fastened and be inserted in feed nozzle 10 and align feed nozzle 10, while several between the two
There is no gap, can so prevent gap of the metal liquid between nozzle 30 and feed nozzle 10 from splashing to outside, cause
The waste of production material.
Due to the Jing of nozzle head 301 be often extended into in feed nozzle 10 or from material mouth 10 in detach, where stress concentration
In nozzle head 301 and the intersection of nozzle body 300, metal fatigue is easily caused herein causes the phenomenon of rupture of metal to be sent out
It is raw, therefore, refering to Fig. 5, the junction of nozzle head 301 and nozzle body 300 is provided with head edge 303, head edge 303
For cylindrical-shaped structure body, and the external diameter at head edge 303 so, effectively eliminates spray more than the external diameter of the nozzle body 300
Mouth portion 301 and the internal stress of the junction of nozzle body 300, prevent its forced breakage, and the use longevity of nozzle 30 is increased significantly
Life.
Although opening 100 is fitted close with the nozzle head 301 of nozzle 30, nozzle head 301 still relative can be opened
Mouth 100 makees tiny axial movement, this situation is not intended to during pressure injection molten metal and is occurred, therefore, nozzle head
301 is frustum cone structure body, is additionally provided with convex edge 302 on the circumference of the frustum cone side of nozzle head 301, the opening 100 it is interior
Provided circumferentially about have a recessed edge (not indicating in figure), the convex edge on the recessed edge and the frustum cone side circumference of the nozzle head 301
302 coordinate, and by the friction on cooperation increase nozzle head 301 and the inwall axial direction of opening 100 of the recessed edge with convex edge 302, prevent
Relative displacement on both axial directions.
In the present embodiment, the fastening part 102, transition part 103, feed nozzle main body 101 are disposed as cylindrical-shaped structure.
To make molten metal during die sinking not flow out from nozzle 30, nozzle 30, mould 1, feed nozzle 10 are inclined upwardly setting,
Angle of inclination is 8 degree to 20 degree.
Preferably, angle of inclination is 12 degree to 15 degree, and 12 degree to 15 degree of oblique angle is angle the most suitable, if this angle
More than 15 degree, nozzle 30 easily causes molten metal to be difficult to injection die cavity by Action of Gravity Field because being too greatly inclined during injection of metallic liquid, if
Angle of inclination is that, less than 12 degree, molten metal yet suffers from the possibility oozed from nozzle 30 during die sinking.
It is below matched moulds workflow, comprises the following steps：
Step A00：Mould 1 is positioned on die holder；
Step B00：Cylinder action, drives moving platen 2 to move to right, and drives left mould motion, and left mould and right mould are fastened, and forms gold
The die cavity of category liquid molding；
Step C00：Feed nozzle 10 on the nozzle 30 and mould 1 of injection mechanism 3 is coordinated, mould 1 makes spray toward moving right
Mouth portion 301 touches the opening 100 of feed nozzle 10, and the micro mould 1 that swings allows the opening 100 of feed nozzle 10 to be directed at spray
Nozzle 30 is nested in the opening 100 of feed nozzle 10 behind mouth portion 301, feed nozzle 10 and nozzle 30 are fastened into fit.Charging
Mouth 10 is first contacted with nozzle 30, then it is micro swing be directed at nozzle 30 after fasten fit, can not phase both after fit
To swinging, it is ensured that be fully aligned between feed nozzle 10 and nozzle 30, improve pressure injection quality.
Die feeding mouth structure and matched moulds technique that the utility model passes through a kind of horizontal plunger die casting machine of offer, in feed nozzle
On be dexterously provided with for the fastening part of firmly nested nozzle, making the whole nozzle head of nozzle can be nested, two
It is not easy relative loosening between person, nozzle and feed nozzle can be accurately judged when feed nozzle relative nozzle is fixed to positive alignment,
And good cooperation between the two prevents gap of the metal liquid between nozzle and feed nozzle from splashing to outside, it is to avoid cause life
Produce the waste of material.
It should be appreciated that application of the present utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
Say, can according to the above description be improved or be converted, all these modifications and variations should all belong to the appended power of the utility model
The protection domain that profit is required.
