Technical Field
The utility model relates to the technical field of vulcanization equipment, in particular to rubber injection vulcanization equipment.
Background
Compared with the traditional rubber vulcanizing machine, the rubber injection vulcanizing machine has the advantages of high vulcanizing efficiency, low labor intensity of workers and the like. However, the rubber injection machine which is conventionally sold in the market at present is generally not more than 40kg of rubber material injected in one time except for a silicone rubber injection machine due to the restriction of the size of an injection charging barrel. Therefore, the method is greatly restricted in the production of large-scale rubber products, and can only be vulcanized by adopting the traditional manual rubber filling, molding and vulcanizing mode.
Disclosure of Invention
The utility model aims to provide rubber injection vulcanizing equipment which has the characteristics of large rubber injection quantity and high efficiency.
The technical scheme adopted by the utility model is as follows: the rubber injection vulcanizing device comprises an injection unit and a vulcanizing machine, wherein the vulcanizing machine is provided with a hot plate and a mold, the mold is provided with a cold runner, an upper hot plate and a lower hot plate, an injection port of the injection unit is connected to the cold runner, the injection unit is respectively arranged at the left side and the right side of the vulcanizing machine, and plasticizing barrels are vertically connected at the injection port of the injection unit.
The 4 injection units are independently controlled.
The 4 injection units are controlled in a linkage way.
And cold runner plates are fixed on the upper and lower hot plates.
And the cold runner plate is connected with a cooling water tower.
The injection points of the die are arbitrarily switched between 1 and 12.
And the injection unit and the plasticizing charging barrel are both in signal connection with a PLC.
The hot plate size of the vulcanizing machine is 3.5mX3.5m, and the mold locking force is 4000t.
The utility model has the advantages that: the glue injection amount is large and the efficiency is high. Compared with the traditional injection vulcanizing machine, the rubber injection vulcanizing device adopts 4 injection units, the total injection quantity of a single time can reach 160kg, and the bottleneck that rubber products with large rubber quantity cannot be produced by adopting an injection vulcanizing process is solved. Meanwhile, the 4 injection units can be independently controlled, or two injection units can be used for injection first, and the other two plasticizing units are used for plasticizing and then are used for plasticizing in turn, so that the efficiency can be greatly improved. And the larger hot plate size is convenient for producing larger products. For the flowing distance of the sizing material on the hot plate exceeds 2m, in order to ensure that the sizing material flowing on the hot plate does not have scorch, a cold runner plate is added.

Detailed Description
Examples are shown in fig. 1 and 2: the rubber injection vulcanizing device comprises an injection unit 10 and a vulcanizing machine 20. The vulcanizer 20 has a hot plate and a mold 30, the mold 30 having a cold runner to which an injection port of the injection unit 10 is connected.
Further speaking:
the injection units 10 are respectively arranged at the left side and the right side of the vulcanizing machine 20, and plasticizing cylinders 60 are vertically connected at the injection ports of the injection units 10. That is, the left and right sides of the vulcanizer 20 are provided with 2 injection units 10, respectively, while the plastic barrels 60 are generally vertically connected and located below the corresponding injection units 10. Meanwhile, the 4 injection units 10 can be independently controlled and also can be controlled in a linkage way. That is, the plurality of injection units 10 may be operated individually or in combination to meet the need for a large amount of glue, and the maximum possible injection is 160Kg without repeated injection. And the vertically connected plasticizing cylinder 60 is convenient for feeding the glue.
Optimizing:
the upper and lower hot plates are secured with cold runner plates 40. The cooling flow channel plate 40 can be cooled in various ways, and in this embodiment, the cooling flow channel plate 40 is connected with a cooling water tower 50, and the cooling water tower 50 can be configured with a temperature control component. That is, the temperature is reduced by the cooling water, and the temperature is regulated by the temperature control component, so that a better cooling effect is achieved, and scorching is avoided.
The cold runner of the mold 30 has at least 1 injection point. In this example, the number of injection points is 12. That is, the plurality of injection points can be arbitrarily switched from 1 to 12 points, so that the length of the hot runner of the mold can be reduced to the maximum.
Further optimizing:
the injection unit 10 and plasticizing cylinder 60 are both signally connected to a PLC70. That is, the start and the close of any one injection unit 10 and any one plasticizing cylinder 60 can be controlled by the PLC70, so that the injection amount and the injection timing can be controlled more easily.
The hot plate size of the vulcanizing machine 20 is 3.5m×3.5m, and the mold locking force is 4000t, so as to meet the requirement of producing rubber products with larger sizes.
In operation, the mold 30 is first preheated to the desired temperature for production while the upper and lower hot plates, plasticizing cylinder, cold runner plate 40 are heated to the desired temperature for the process. The injection amounts of the 4 injection units 10 are set according to the product demand, respectively, and then the 4 plasticizing cylinders 60 are opened. After plasticizing is complete, the mold 30 is pressurized to the pressure required for vulcanization. After the pressurization is completed, the injection is started by the 4 injection units 10, and the 4 injection units can be injected simultaneously or independently. If the single glue consumption of the die is larger than 160kg, secondary injection can be adopted, namely, after the injection of the 4 injection units 10 is finished, secondary plasticization is carried out within the time of the safe operation of the glue stock, and the repeated action is carried out after the plasticization is finished. After the injection is completed, the mold 30 is vented to prevent product air pockets. After the exhaust is completed, the pressure is maintained, and meanwhile, the temperature of the cold runner plate 40 is reduced, so that the cold runner sizing material is prevented from being burnt. Then, vulcanization is performed according to the process vulcanization time. And taking out the product after the vulcanization is finished.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes using the descriptions and drawings of the present utility model or directly or indirectly applied to other related technical fields are included in the scope of the utility model.
