Description
Technical Field
The utility model relates to the field of injection molding machines, in particular to an injection mold for a plastic packaging box.
Background
When producing plastic packaging box through the injection molding machine, because the plastic box main part is thin wall structure, the material chamber passageway is narrower when moulding plastics, and single channel is moulded plastics and is made the material uneven distribution easily, in addition, when the drawing of patterns after the product shaping, the damage appears under the effort of the easy young ejecting device of thin wall structure.
Disclosure of Invention
Aiming at the defects existing in the prior art, the utility model aims to provide the injection mold for the plastic packaging box, which solves the existing pain point in the field.
The technical aim of the utility model is realized by the following technical scheme:
the utility model provides a plastic packaging box injection mold, includes compound die and injection mold, compound die with the combination is the shaping chamber between the injection mold, be provided with the passageway of moulding plastics in the injection mold, the passageway of moulding plastics with shaping chamber middle part is connected, the passageway of moulding plastics side is provided with many reposition of redundant personnel passageways, the reposition of redundant personnel passageway with shaping chamber edge connection, lean on in the shaping chamber sliding mounting has the push pedal in the wall of compound die, push pedal and fixed mounting in the flexible end connection of the outer ejecting pneumatic cylinder of compound die, the push pedal is wide face structure, compound die side articulates there is the clamp plate, the clamp plate articulated department is provided with the torsional spring, the clamp plate can be with the finished product spare pressure stay in the compound die when dividing the mould, and can be by the top when the push pedal is ejecting the drawing of patterns.
In summary, compared with the prior art, the utility model has the following beneficial effects: an injection channel and a shunt channel are arranged in the injection mold, and materials are injected into the forming cavity through a plurality of channels, so that the materials can be ensured to fill the forming cavity, and meanwhile, the injection rate can be increased; in addition, the ejection device in the die assembly mold is provided with a wide-surface push plate, so that the pressure intensity is reduced through a larger contact area when the material is ejected, and the damage of the product is avoided; the die assembly die is provided with the pressing plate, a forming cavity can be formed together with the die assembly die and the injection die, a product can be pressed to be remained on the die assembly die during die separation, and then the pressing plate is pushed to be ejected by the pushing plate to finish die stripping.
Drawings
The above, as well as additional purposes, features, and advantages of exemplary embodiments of the present utility model will become readily apparent from the following detailed description when read in conjunction with the accompanying drawings. Several embodiments of the present utility model are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which:
fig. 1 is a schematic structural view of an injection mold for a plastic package box.
Reference numerals illustrate: 1. closing the mold; 2. an injection mold; 3. a molding cavity; 4. an injection molding channel; 5. a shunt channel; 6. ejecting a hydraulic cylinder; 7. a push plate; 8. and (5) pressing plates.
Detailed Description
The utility model is described in further detail below with reference to the accompanying drawings.
The utility model provides a plastic packaging box injection mold, includes compound die 1 and injection die 2, compound die 1 with make up into shaping chamber 3 between the injection die 2, be provided with injection moulding passageway 4 in the injection die 2, injection moulding passageway 4 with shaping chamber 3 middle part is connected, to penetrate into the material in the shaping chamber 3, injection moulding passageway 4 side is provided with many reposition of redundant personnel passageway 5, reposition of redundant personnel passageway 5 with shaping chamber 3 marginal connection, it can be avoided to carry out the injection moulding through many passageways shaping chamber 3 cavity is too narrow to lead to the material to distribute unevenly in shaping chamber 3, lean on slidable mounting has push pedal 7 in the wall of compound die 1 in the shaping chamber 3, push pedal 7 with fixed mounting in the outer flexible end connection of ejecting pneumatic cylinder 6 of compound die 1, push pedal 7 be wide face structure with plastic part area of contact in the shaping chamber 3 is great, can be in compound die 1 with after injection die 2 divides the mould will release, and not fragile finished product.
The side of the die closing die 1 is hinged with a pressing plate 8, the hinged position of the pressing plate 8 is provided with a torsion spring, the pressing plate 8 can be pressed by the injection die 2 during die closing, the pressing plate 8 can press and retain a finished product in the die closing die 1 during die parting, and the pressing plate 7 can be ejected when ejecting and demolding the finished product, so that the finished product can be smoothly dropped.
The foregoing is merely exemplary embodiments of the present utility model and is not intended to limit the scope of the utility model, which is defined by the appended claims.
