[0034] In this embodiment, the flip block 40 and the flip seat 50 are respectively arranged in two groups and are distributed on the same side of the mold. By setting a rotating flip mechanism, the operation steps of mold opening and mold closing are simplified and the stability of mold opening and mold closing is improved.

[0035] By setting up a rotary flipping mechanism, during the process of opening and closing the mold, by setting up a sliding groove 51, one end of the flipping block 40 can move up and down in the sliding groove 51, so that the opening and closing stroke of the rotary flipping mechanism becomes larger, and the stroke can be adjusted according to different types of molds to adapt to the use of various molds, without the need for specific processing of the mold, thereby simplifying the processing difficulty of the mold.

[0036] Preferably, the flip block 40 includes a first connecting portion 42. Two groups of fixing portions 43 extending outward are provided at one end of the connecting portion. A first protrusion 44 extending downward is provided at the other end of the first connecting portion 42, and the first connecting portion 42 is located in the flip seat 50. By providing the fixing portion 43, the contact surface between the flip block 40 and the flow channel plate 21 is enlarged, which facilitates the fixation between the flip block 40 and the flow channel plate 21 and improves the connection strength between the two. At the same time, by providing the first protrusion 44, the first protrusion 44 is slidably connected to the sliding groove 51, and the opening and closing stroke between the flip block 40 and the flip seat 50 is enlarged to adapt to the use of various molds.

[0037] Furthermore, two groups of fixing portions 43 are symmetrically distributed on both sides of the first connecting portion 42, and the surface of the first connecting portion 42 is flush with the surface of the fixing portion 43, and is integrally formed with the first connecting portion 42. The fixing portion 43 is fixedly connected to the flow channel plate 21. By integrally forming the fixing portion 43 and the first connecting portion 42 to form a "T"-shaped structure, production and processing are facilitated, and production difficulty is reduced.

[0038] Furthermore, the first protrusion 44 is vertically arranged with the first connection part 42 and is integrally formed with the first connection part 42. The first protrusion 44 is slidably connected to the sliding groove 51. By integrally forming the first protrusion 44 with the first connection part 42 to form an "L"-shaped structure, and the first protrusion 44 and the fixing part 43 are vertically arranged, it is easy to produce and process, and the production difficulty is reduced.
