Description

Injection mechanism of first-in first-out injection machine with horizontal structure

Technical Field

The utility model relates to a rubber injection moulding equipment, concretely relates to horizontal structure's first-in first-out injection machine's injection mechanism.

Background

First-in first-out rubber injection machines refer to: rubber enters the storage barrel after being plasticized by the screw, the rubber material is stored along the length direction of the storage barrel in the plasticizing feeding process, the rubber material which enters the storage barrel firstly is injected into the mold during material injection, and the induction time (the preparation time from the plasticizing of the rubber material to the beginning of the crosslinking reaction) can be shortened. The rapid rise of the temperature of the sizing material is an important factor for ensuring the production efficiency and quality. Because a certain time is needed for feeding enough rubber, the heating quantity of the rubber which is firstly fed into the injection charging barrel is larger than that of the rubber which is fed later, and the heating quantity of the rubber which is finally filled stays in the charging barrel and is finally injected out, so that the rubber with less heating quantity can also generate the same amount of intermediate products, and the difference of the plasticizing degrees caused by inconsistent heating degrees can be compensated.

Some rubber products are more advantageous to be produced by an injection machine with a first-in first-out injection function due to the characteristic that the molding time requirement is short. Silica gel-like products have higher temperature sensitivity because of different properties from common rubber, and the heat load should be reduced as much as possible in the production process. In the feeding and plasticizing process, the rubber material is filled into the injection charging barrel by the thrust generated by the rotation of the screw, the injection piston and a mechanism connected with the injection piston are pushed backwards by the reaction force of the screw, the larger the resistance is, the larger the plasticizing energy obtained by the rubber material is, and the temperature is increased along with the plasticizing energy. The vertical type structure of the first-in first-out injection machine is commonly used in the market at present, and the vertical type structure has the defect that because the injection part is in the vertical direction, constant pressure is generated due to the large mass of the vertical type structure (gravity of structures such as an injection cylinder level injection plunger and the like), and the temperature of rubber materials is higher or uncontrollable. The horizontally arranged injection structure does not have constant back pressure, and only the friction force needs to be compensated. In addition, because the height of the vertical structure body is high, the injection part can be further raised in the filling process, and the difficulty is increased in filling the common rubber or filling the silica gel by additionally arranging the silica gel feeding barrel. An excessively high height both increases the risk of filling and places demands on the height of the building. The limitation of height requirement of the factory building prevents many small and medium-sized enterprises from using the equipment with the structure. In order to promote the equipment with the first-in first-out structure and prevent the equipment from being influenced by the height, the horizontal structure is changed into the vertical structure.
