[0005] Preferably, a fixing plate pressing plate is provided at the bottom of the fixing plate, and the ejector pin passes through the fixing plate pressing plate.

[0006] Preferably, spring mounting holes are vertically arranged in the fixed plate, the pressure plate and the push plate, and springs are vertically arranged in the spring mounting holes.

[0007] Preferably, screw mounting holes are vertically arranged in the fixing plate, the fixing plate pressure plate and the pushing plate, and limiting screws are vertically arranged in the screw mounting holes.

[0008] Preferably, a positioning column is vertically arranged on the fixing plate.

[0009] Preferably, a push plate pressure plate is provided at the bottom of the push plate.

[0010] The beneficial effect of the utility model is that the jig for quickly installing terminals in buried injection molding of the utility model can install small inserts in batches, and then enter the mold with the jig, which greatly shortens the time for installing inserts in production, thereby greatly shortening the entire product molding cycle, improving production efficiency, and is suitable for the production of most injection molded products with small inserts.
