The injection mechanism is characterized in that a smelting function is separated from an injection function. Raw materials are platicized by an extruding device and conveyed into a plunger-type injection device, and then molten plastics is injected into a mould through the plunger-type injection device; the independent extruding device is used for smelting glue, the glue smelting speed is fast, more uniformity in plasticization is realized, and high quality of a product can be guaranteed; the plunger-type injection device can provide vast injection quantity, and the injection precision is high; and an optimized sealing device is introduced, so that reliability in use is achieved, no glue is leaked, and rapidness in switching the sealing can be achieved. The two-step injection mechanism has advantages that when the vast injection quantity is satisfied, the integral structure is simpler and more convenient, and more convenience in installation is realized; and moreover, when the injection quantity is highly required, the requirement can be met only by slightly changing the plunger-type injection device, so that the universality is stronger, and good application and popularization value can be realized.

In the described injection mechanism, it is characterized in that: melten gel separates with the injection function.Raw material is in extrusion device plastifies and be transported to plunger type injection device, then by the plastics injection mould of plunger type injection device with fusion;
In the described injection mechanism, it is characterized in that: independently extrusion device carries out melten gel, and melten gel speed is fast, plastifies more evenly, guarantees that product is high-quality;
In the described injection mechanism, it is characterized in that: plunger type injection device, the super large injection volume can be provided, the injection precision is higher;
In the described injection mechanism, it is characterized in that: introduce the sealing device of optimal design, use reliably, do not leak glue, sealing is switched rapidly.
When the advantage of the utility model was to satisfy the super large injection volume, overall structure was more easy, installed more convenient; And require when higher for injection volume; Only need slight change plunger type injection device just can meet the demands, versatility is stronger, has value for applications preferably.
