Novel pressurization injection molding mechanism and high-efficiency bottle blowing machine thereof

Abstract

The invention belongs to the technical field of plastic bottle processing, and discloses a novel pressurization injection molding mechanism and a high-efficiency bottle blowing machine thereof. The novel pressurization injection molding mechanism comprises an upper locking mould plate, a locking mould guide pillar, a lower locking mould plate, a pressurization oil cylinder, an injection molding box, a mould frame oil cylinder, an injection core and a lower mould plate, wherein the upper locking mould plate and the lower locking mould plate are arranged at two opposite ends of the locking mouldguide pillar; a main body of the mould frame oil cylinder is arranged on one side, facing the lower locking mould plate, of the upper locking mould plate; a piston rod of the mould frame oil cylinderis connected with the injection core; the lower mould plate is slidably arranged on the locking mould guide pillar in a sleeving way; the injection molding box is arranged on one side, facing the upper locking mould plate, of the lower mould plate; a main body of the pressurization oil cylinder is arranged on one side, deviated from the upper locking mould plate, of the lower mould plate; and a piston rod of the pressurization oil cylinder is connected with the lower locking mould plate. The occurrence of the phenomenon that engine oil of the pressurization oil cylinder leaks into the injection molding box so as to pollute a plastic parison is avoided, and high-efficiency and high-quality production of plastic bottles can be ensured.

Description

technical field [0001] The invention belongs to the technical field of plastic bottle processing, and in particular relates to a novel pressurized injection molding mechanism and a high-efficiency bottle blowing machine thereof. Background technique [0002] Plastic hollow containers are widely used in the beverage, medicine, cosmetics, food and chemical industries due to their light weight, low price, high safety and other characteristics. It has attracted more manufacturers to choose plastic containers to replace the previous glass containers. The most advanced equipment, molds and raw materials in today's plastic industry are all displayed in front of us one by one. New technologies and new applications are emerging one after another. Looking at the field of plastic hollow molding is also fruitful. With the soaring price of oil in the world, the price of plastic raw materials is also high. The development of alternative products with low energy consumption and low raw mat...

Problems solved by technology

[0005] In order to solve the above-mentioned problems existing in the prior art, the object of the present invention is to provide a novel pressurized injection molding mechanism and its high-efficiency bottle blowing machine, which avoids the oil leakage of the pressurized cylinder after placing the pressurized cylinder at the lower part of the lower template. In the case of polluting the plastic parison after the injection molding box, the setting of the booster rod can form a pressure on the mold from the upper part. This pressure cooperates with the pressure generated by the booster cylinder to ensure the high-efficiency and high-quality production of plastic bottles.
