Injection molding machine

Abstract

The invention discloses an injection molding machine. The injection molding machine comprises a machine seat, wherein an oil receiver and a water receiver are installed in the machine seat, an injection molding mechanism and a mold closing mechanism are installed above the machine seat, the injection molding mechanism comprises a heater and a threaded rod, the threaded rod is installed in the heater and connected with a servo motor, the heater is provided with two injection molding heads, the inner walls of the heater and the injection molding heads are provided with first cavities, and the first cavities are communicated with the oil receiver; the mold closing mechanism comprises an upper mold body and a lower mold body, the upper mold body is connected with a driving air cylinder, a moldcarrying disc used for installing the lower mold body is installed on the machine seat, a cooling pipeline is arranged in the mold carrying disc, and the cooling pipeline is communicated with the water receiver. The injection molding machine achieves injection through the two injection heads, has the high injection efficiency, and can avoid the situation that production cannot be operated becauseone injection head is abnormal. The injection molding heads are communicated with heat conducting oil, so that the situation that plastics is conveyed to the injection molding heads and cooled and solidified, and accordingly the injection molding heads are blocked is avoided. The mold carrying disc can be cooled through cooling water, thus the lower mold body is cooled, cooling of the plastic product is accelerated, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plastic production equipment, in particular to an injection molding machine. Background technique [0002] Injection molding is to use the thermophysical properties of plastics to put materials from the hopper into the barrel. The outside of the barrel is heated by a heating ring to melt the materials. A screw connected to the injection motor is installed in the barrel. The material is driven by the screw along the The screw groove is conveyed forward and compacted, and the material is gradually plasticized, melted and homogenized under the double action of external heating and screw shearing. The melted material is pushed to the head of the screw, and at the same time, the screw retreats under the reaction of the material, so that the head of the screw forms a storage space and completes the plasticizing process. Then, the screw is driven by the piston thrust of the hydraulic system to With high speed a...
