Description

Wax pressing spiral conveying device Technical Field The utility model relates to the technical field of wax pressing conveying, in particular to a wax pressing spiral conveying device. Background At present, a common wax liquid conveying mode is to drive a piston in a wax cylinder to move by means of a linear actuator. During this process, the movement of the piston causes a pressure change in the wax liquid in the wax cylinder, thereby pressing the wax liquid into the delivery channel. And then, the wax liquid flows along the conveying channel, finally is injected into the die through the injection nozzle, and the preliminary transfer of the wax liquid in the die production is completed, so that a foundation is laid for the subsequent processes such as forming and the like. However, after intensive research on this prior art, it is not difficult to find that it exposes a number of problems to be solved in practical applications. Among them, the problems of regulation and stability of wax injection amount are particularly remarkable. Since the whole wax injection process is realized almost completely by the linear movement of the piston, the stability of the flow of the wax liquid has a decisive influence on the wax injection effect. In a practical production environment, various factors interfere with the stable flow of the wax liquid, such as temperature variation of the wax liquid itself, roughness of a conveying pipeline, and fine fluctuation of the internal pressure of the wax cylinder. Once the flow of the wax liquid is unstable, the amount of the wax liquid emitted from the nozzle is difficult to maintain in a precise state, which not only can cause uneven molding quality of the wax mold in the mold and influence the dimensional accuracy and surface finish of the product, but also can cause more problems in the subsequent processing procedures, increase the rejection rate and increase the production cost. In addition, different moulds have differences in design and application scenes, and the requirements on wax injection amount are different. However, the prior art simply relies on controlling the movement of the piston to adjust the wax injection amount, and has obvious limitations. The motion mode of the piston is relatively single, and the refined wax injection quantity control is difficult to realize according to the complex requirements of different dies. The prior wax pressing conveying technology is not attractive when facing diversified die production tasks, and cannot meet the requirements of the modern die manufacturing industry on efficient and accurate production. In summary, the problems of the conventional wax injection delivery technology in terms of wax injection quantity adjustment and stability severely restrict the quality and efficiency of mold production, and a new technical scheme needs to be developed for improvement.
