Abstract
The utility model relates to a rubber/plastic screw rotary injection molding device for a rubber/plastic machine, comprising a machine cylinder (1), a screw rod (2), a machine head opening mould (4) and a mould (7). The utility model is characterized in that a flow channel is formed between the machine head opening mould and a conical screw rod head (3), and thus the injection molding device is formed by a nozzle (5), etc. The utility model having the advantages of simple structure, small size, low energy consumption, low cost for equipment and products, high quality for the products can be used for the injection molding of large material products with high viscosity.
Description
The utility model relates to the improvement of the Coinjection molding apparatus of a kind of rubber, plastics machinery.
The injector of rubber, plastics and the modification material thereof that uses both at home and abroad generally adopts the reciprocating screw Coinjection molding apparatus at present, it is that material is added in the preplasticizer, material obtains plasticizing by the effect of screw rod one barrel system, screw rod is pushed material to head, screw rod moves backward, after the head inner chamber accumulates to certain volume, axially injection device is with the screw rod forward impelling, material is injected into mould, this arbor needs very big motive force to injection device, institute power consumption source is very big, and structure is quite complicated, difficult in maintenance.
The purpose of this utility model provides a kind of improved screw rotation injection moulding device, thereby saves axial injection device, simplifies the structure of Coinjection molding apparatus, saves cost of equipment, cuts down the consumption of energy.
The purpose of this utility model realizes by following measure, have machine barrel (1), screw rod (2), machine head port mould (4), mould (7), adorning screw rod in the machine barrel, the machine barrel front end is connected to machine head port mould, this apparatus features is that screw front end is equipped with conical screw head (3), constitutes runner between machine head port mould and the conical screw head, the machine head port mould front end is equipped with nozzle (5), the spray nozzle front end mould (7) of ining succession.
The utility model has the advantages that simple in structurely, volume is little, saves the energy, reduces cost of equipment, improves quality of item, reduces the goods cost, realizes injection mouldings large-scale, the high viscosity goods.
Description of drawings is as follows:
Figure is the structural representation of rubber, plastics rotation injection moulding device.
The utility model will be further described in conjunction with the accompanying drawings, when rubber or plastics, or its modification material enters routine screw rod one barrel system, then screw rod rotates with certain rotating speed, the material of feeding is plastified, and the material after the plasticizing is continuously pushed material to constitute between machine head port mould and the conical screw head runner under the effect of rotary screw thrust, enter nozzle, inject mold cavity (8) through injection flow passage.After material was filled with in the die cavity, injection device broke away from injection flow passage, and screw rod stops the rotation, after goods in the die cavity are vulcanized or cooling off, open mould and take out goods, matched moulds subsequently, the nozzle of injection device is advanced to the injected current road junction again, and screw rod continues rotation, carries out the injection process of following one-period.
Claims (1)
1, the rubber of a kind of rubber, plastics machinery, plastic screw rotation injection moulding device, having inside is equipped with the machine barrel of screw rod (2) (1) and holds before and connecting machine head port mould (4), mould (7), the front end that it is characterized in that screw rod is equipped with conical screw head (3), constitute runner between machine head port mould and the conical screw head, the front end of machine head port mould is equipped with nozzle (5) the spray nozzle front end mould (7) of ining succession.
