The utility model relates to the technical field of the plastic molding, in particular to an one-step injection and blow model which can realize injecting and blowing synchronously on one set of the model. The utility model consists of a fixed model, a movable model, an injecting part, a blowing part. On one side of the movable model, a drive mechanism which connects with the movable model by a gearing is arranged. The fixed model is arranged with at least one injection hot-runner system. The movable model is arranged with at least one blow mouth in which a mandril is arranged, the mandril matches to the injection hot-runner system of the fixed model, the fixed model is arranged with at least one product-finishing die cavity, and the product-finishing die cavity corresponds to the blow mouth. The utility model has the advantages of that the stucture is simple, the operation technique is easy, and the finished product produced by the utility model has a higher precision and a high production efficiency.
Description
Technical field:
The utility model relates to the plastics forming technique field, refers in particular to a kind of one-step injection blower mould that can realize injection moulding and blowing on a mold.
Background technology:
In the blow molded product molding process of plastics, traditional handicraft adopts and extrudes---blow molding method, the product that this method is produced, the protrusion crack that appearance can not be eliminated on product surface, make product surface not attractive in appearance, rough, and unnecessary leftover pieces appear inevitably, cause the waste of raw materials for production and increased the cost of formed product.
Defective in view of above-mentioned technology, people develop a kind of notes again---blow the method for hollow molding blow molded product, its method is to inject parison earlier, forward to again to heat on the blow moulding machine and be blown into hollow container, this processing method, production link is many, and equipment investment is big, complex forming technology, automaticity are not high.In order to overcome above shortcoming, invented a kind of plastic hollow vessel forming method, see that publication number is the Chinese invention patent of CN1562610A, it mainly is applicable to the horizontal translation mould of two stations, this method is that injection mold separates with blow mold, the parison of injection moulding is transferred to injection mold blow mold in addition again and is just carried out blowing after the injection mold moulding, goes out finished product at last.This method needs the injection machine of special construction, the controlling of production process difficulty, and one-time investment is big, owing to need transfer mold, the bad control of product quality in process of production.
The utility model content:
The purpose of this utility model is exactly to provide a kind of one-step injection blower mould that can realize injection moulding and blowing on a mold at the weak point of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is: comprise cover half, dynamic model, injection moulding part and blowing part, dynamic model one side is provided with driving mechanism, driving mechanism is connected with dynamic model by power drive mechanism, and cover half is provided with at least one injection heat runner system, and dynamic model is provided with at least one blowing mouth, be provided with plug in the blowing mouth, plug cooperates with the injection heat runner system of cover half, and cover half is provided with at least one finished product die cavity, and the finished product die cavity is corresponding with the blowing mouth.
The dynamic model below also is provided with base.
Described power drive mechanism comprises driving gear that is connected with driving mechanism and the travelling gear that is connected with dynamic model, and driving gear and travelling gear are intermeshing.
Dynamic model is provided with the air blowing road and is communicated with the blowing mouth.
After adopting said structure, dynamic model rotates under the drive of driving mechanism, when the plug of dynamic model turns to injection heat runner system with cover half at once, can realize the injection moulding of parison, after injection moulding is finished, dynamic model turns over certain angle, make parison just forward the position of cover half finished product die cavity to, at this moment blow by the air blowing road, die sinking and then is rotated and is finished next cycle from bottleneck end face pushing-off product blowing is finished after again, so periodic duty, be implemented on the mold and finish notes---blow operation, so the utlity model has simple in structure, operating procedure is simple, and utilizes the finished product of the utility model production to have the precision height, advantage of high production efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
The specific embodiment:
See shown in Figure 1, present embodiment is an example to make the hollow plastic bottle, it comprises cover half 1, dynamic model 2, injection moulding part and blowing part, dynamic model 2 one sides are provided with driving mechanism 3, driving mechanism 3 is connected with dynamic model 2 by power drive mechanism 4, cover half 1 is provided with at least two injection heat runner systems 5, dynamic model 2 is provided with four blowing mouths 6, four blowing mouth 6 rectangular layouts, be provided with plug 7 in the blowing mouth 6, plug 7 cooperates with the injection heat runner system 5 of cover half 1, cover half 1 is provided with two finished product die cavitys 8, at two finished product die cavitys 8 of synchronization with wherein two blowing mouths 6 are corresponding one by one, two injection heat runner systems 5 and two also rectangular layouts of finished product die cavity 8 of cover half 1, and two injection heat runner systems 5 and two finished product die cavitys 8 are in twos at interval.
Described power drive mechanism 4 comprises driving gear 41 that is connected with driving mechanism 3 and the travelling gear 42 that is connected with dynamic model 2, and driving gear 41 and travelling gear 42 are intermeshing.
Operation principle: in the present embodiment, during beginning, two finished product die cavitys 8 are with wherein two blowing mouths 6 are corresponding one by one, two plugs 7 are corresponding one by one with two injection heat runner systems 5, behind the matched moulds, come into effect the bottle base injection moulding, after injection moulding was finished, driving mechanism 3 drove dynamic model 2 and turns over 90 degree, at this moment, bottle base turns to finished product die cavity 8 belows with cover half 1, the corresponding finished product die cavity 8 of bottle base carries out blowing by air blowing road 10 to 6 air blowings of blowing mouth, and bottle base is blow molded into the bottle finished product of hollow in finished product die cavity 8, die sinking is from bottleneck end face pushing-off product, and then revolves and turn 90 degrees the production of finishing next cycle.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
