[0028] Among them, the positioning structure also includes a position limiting screw 104; four position limiting screws 104 are arranged, and the four position limiting screws 104 are evenly distributed and threadedly connected to the front and rear sides of the fixed mold mounting seat 1, and the four position limiting screws 104 are respectively spline-connected to four power transmission gears 105, and the four position limiting screws 104 are respectively threadedly connected to two primary injection fixed mold cores 3 or two secondary injection fixed mold cores 5.
[0029] Among them, the positioning structure also includes a cooling box 106 and a coolant delivery pipe 107; two cooling boxes 106 are provided, and the two cooling boxes 106 are respectively bolted to the front and rear sides of the fixed mold mounting base 1, and the inner sides of the two cooling boxes 106 are bolted to a small coolant pump; two coolant delivery pipes 107 are provided, and the two coolant delivery pipes 107 are respectively located in the middle of two primary injection fixed mold cores 3 or two secondary injection fixed mold cores 5, and the two coolant delivery pipes 107 are respectively fixedly connected to the output ends of two small coolant pumps.
[0030] The specific usage and function of this embodiment are as follows: the movable mold mounting seat 2 is moved downward to align the fixed mold core 3 of the primary injection with the movable mold core 4 of the primary injection, and the fixed mold core 5 of the secondary injection with the movable mold core 6 of the secondary injection, and the raw material is injected between the fixed mold core 3 of the primary injection and the movable mold core 4 of the primary injection. After the primary core material is formed, the movable mold mounting seat 2 is opened, and the robot takes out the primary core material and puts it on the fixed mold core 5 of the secondary injection, and the movable mold mounting seat 2 is moved downward again, and the raw material is injected between the fixed mold core 5 of the secondary injection and the movable mold core 6 of the secondary injection to complete the secondary injection, and the raw material is injected.

At this time, the first injection fixed mold core 3 or the second injection fixed mold core 5 will squeeze the position limiting block 101, so that the position limiting block 101 slides with the power transmission rack 103, thereby moving the position limiting screw 104 outward. After placing the first injection fixed mold core 3 or the second injection fixed mold core 5, the position limiting block 101 is reset to allow the position limiting screw 104 to be inserted into the new first injection fixed mold core 3 or the second injection fixed mold core 5.
