[0024] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0025] like Figures 1 to 3 As shown, a quantitative injection molding equipment for the production of injection molded parts includes three legs 1, a stirring box 2 is fixedly connected to the upper side of the three legs 1, a stirring box cover 3 is fixedly connected to the upper side of the stirring box 2, two support columns 4 are fixedly connected to the upper side of the two support columns 4, a placement plate 5 is fixedly connected to the upper side of the placement plate 5, a pressure sensor 6 is fixedly connected to the upper side of the placement plate 5, a discharge box 7 is fixedly connected to the upper side of the pressure sensor 6, a stirring device 8 is provided inside the stirring box 2, and two feeding pipes 9 are symmetrically connected to the bottom end of the discharge box 7, and one end of the two feeding pipes 9 extends to the inside of the stirring box 2. The material is placed in the discharge box 7, and the pressure sensor 6 can detect the weight of the material. When the appropriate material is placed, the control panel 14 prompts to stop the discharge, thereby avoiding the discharge error caused by manual discharge.

[0026] The stirring device 8 includes a stirring motor 10, which is fixedly connected to the upper side of the stirring box cover 3. The output end of the stirring motor 10 is fixedly connected with a stirring shaft 11, and one end of the stirring shaft 11 is rotatably connected to the bottom end of the stirring box 2. A stirring blade 12 is fixedly connected to the outer side of the stirring shaft 11, and the outer side of the stirring blade 12 is arc-shaped and contacts the inner wall of the stirring box 2. A notch is provided at the bottom end of the stirring box 2, and a discharge bin 13 is fixedly connected to the bottom end of the stirring box 2. A control panel 14 is fixedly connected to the upper side of the stirring box cover 3. The stirring motor 10 is electrically connected to the control panel 14, and the pressure sensor 6 is electrically connected to the control panel 14. The stirring motor 10 drives the stirring shaft 11 to rotate, and the transmission stirring blade 12 rotates.
