Technics for manufacturing plastic products based on ejection principle and device thereof

Abstract

The invention discloses a technique which manufactures a plastic product by integrating the injection principle and includes the steps of die-setting, material storage, connection, extrusion of material and filling, removal of shuttering and so on; the invention also discloses a device used for realizing the technique, which includes an extruder and a mold, the extruder has a feed passage, an extrusion storage vat and at least one reserve storage vat are arranged along the feed passage, an oil-pressure device is arranged in the extrusion storage vat and the reserve storage vat, a control valve is arranged between the extrusion storage vat and the reserve storage vat, a discharge pipe connecting with the mold is arranged on the storage vat, and the discharge pipe is provided with a valve; the molding charge for manufacturing ultra-heavy or complex article can be reduced and the injection molding cost can be lowered if the invention is adopted.

Description

Technical field [0001] The present invention relates to a product manufacturing process, in particular to a process for manufacturing plastic products such as filter barrels for filters in combination with the injection principle. The present invention also relates to a device for manufacturing plastic products using the injection principle. Background technique [0002] The traditional way of using injection molding machine to make plastic products is that the screw of the injection molding machine continuously mixes and spits out the plastic, and then squeezes the plastic into the mold. The production of the injection molding machine is to close the mold, injection molding, cooling, and opening the mold. The finished product is ejected, and the mold is closed again... Repeat this cycle, each action is intermittent, due to the limitation of the screw's discharge volume, some items that require overweight or complex structure, only use the injection molding machine It is impossib...

[0002] The traditional way of using injection molding machine to manufacture plastic products is that the screw of the injection molding machine continuously mixes and spits out the plastic, and then extrudes the plastic into the mold. The production of the injection molding machine is to close the mold, injection molding, cooling, and mold opening. Eject the finished product, and then close the mold... Repeat this cycle, each action is intermittent, due to the limitation of the output of the screw, some items that require overweight or complex structures, simply use the injection molding machine It is impossible to produce one-piece overweight or complex-structured items, so it is necessary to inject the parts of the overweight or complex-structured items separately, and then assemble the parts together, which will inevitably increase the cost of mold opening. The equipment investment is too large and the required weight of the finished product cannot be achieved
