The bottom plate 10 is provided with a plurality of clamping parts 11 for fixing the clamping assembly.

The clamping assembly includes a fixed seat 21, at least one movable splint 22 arranged on the fixed seat 21, a driving rod 23 connected to the movable splint 22, and a locking mechanism fixed at the end of the driving rod 23 away from the movable splint 22. piece 24. The fixing seat 21 is flat and the size of the fixing seat 21 does not exceed the bottom plate 10 . In this embodiment, the bottom plate 10 and the fixed seat 21 are both arranged in a rectangular shape, and the front and rear sides of the bottom plate 10 and the fixed seat 21 are flush with each other in the moving direction of the movable splint 22; the other side of the bottom plate 10 A group of sides protrude from the fixing seat 21 . There are four clamping members 11 arranged symmetrically on a set of sides of the bottom plate 10 beyond the fixing seat. When the clamping assembly is placed on the bottom plate 10 , the front and rear direction of the control fixing seat 21 is aligned with the bottom plate 10 , and then the fixing seat 21 is fixed above the bottom plate 10 through the clamping member 11 .

The movable splint 22 is used to form a receiving cavity 25 for receiving the injection molded product 200 . The clamping assembly further includes a fixed splint 26 opposite to the movable splint 22 , wherein the fixed splint 26 is substantially flush with the upper surface of the movable splint 22 . The receiving cavity 25 is formed between the fixed splint 26 and the movable splint 22 . Specifically, the movable splint 22 is arranged in two pieces and is respectively located on two sides of the fixed splint 26 and forms the receiving cavity 25 on both sides of the fixed splint 26 . In other embodiments of the present utility model, the accommodating cavity 25 may also be formed by two movable splints 22 arranged oppositely (not shown).
