Automatic Injection Molding Machine

Abstract

The invention relates to the field of shoe making equipment, and in particular relates to a full-automatic injection molding machine. The full-automatic injection molding machine comprises a mold station, an injection device and a main stander, and is characterized in that the mold station comprises a mold opening and closing oil cylinder, a connection plate mechanism, a guide column, an upper plate, a middle plate and a lower plate; the upper plate and the lower plate are respectively fixed at the upper end and the lower end of the guide column; the middle plate is arranged on the guide column in a sliding manner; a cylinder barrel of the mold opening and closing oil cylinder is fixed on the upper plate; a piston rod of the mold opening and closing oil cylinder is connected with the middle plate through the connection plate mechanism and drives the middle plate to move up and down; the injection device comprises three injection guns which are horizontally arranged side by side; the injection guns comprise material barrels, elbows and material nozzles; one end of each elbow is connected with the material discharging end of each material barrel, and the other end of each elbow is connected with the corresponding material nozzle. The full-automatic injection molding machine provided by the invention can be used for producing single-color, double-color or three-color mixed products; a mold is successfully opened and assembled; the integrality is high, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of shoe-making equipment, in particular to a fully automatic injection molding machine. Background technique [0002] In a traditional injection machine, one injection gun corresponds to one mold, and each mold molds a pair of slippers or soles or other rubber and plastic products each time, and can only produce monochrome products. With the improvement of people's consumption level, monochrome soles It has been far from meeting the needs of the market. [0003] For this reason, some two-color injection machines are designed and improved for the production of two-color soles, such as a kind of two-color rubber injection machine provided by the invention patent application of CN 103264474 A, including vertical injection machines, horizontal injection machines and safety injection machines.

Problems solved by technology

[0002] In a traditional injection machine, one injection gun corresponds to one mold, and each mold molds a pair of slippers or soles or other rubber and plastic products each time, and can only produce monochrome products. With the improvement of people's consumption level, monochrome soles It has been far from meeting the needs of the market.

[0003] For this reason, some two-color injection machines are designed and improved for the production of two-color soles, such as a kind of two-color rubber injection machine provided by the invention patent application of CN 103264474 A, including vertical injection machines, horizontal injection machines and safety injection machines. Protection device, vertical injection machine includes mold clamping system, injection system connected with mold clamping system and oil control system, horizontal injection machine includes horizontal injection machine body, lifting mechanism and guiding mechanism, vertical injection machine and horizontal injection Strip-shaped raw material feeding mechanism is installed on the machine, and the mold clamping system of the vertical injection machine is located in front of the injection nozzle of the horizontal injection machine. Although the two-color rubber injection machine provided by this invention application can be used to produce two-color products, it still has the following deficiencies: 1 1. It can only be used to produce two-color products, but cannot be used to produce single-color or three-color mixed-color products. The scope of use of the equipment is narrow and the utilization rate is not high. 2. Directly use the oil cylinder to open and close the mold, which may easily cause uneven force on the mold , the vibration is severe, which affects the quality of the finished product. 3. A group of injection machines is only used for the production of one mold. When the mold is heated and opened, the injection machine is idle and the production efficiency is low.
