still including ejector beam 5, first rectangular plate 1a level sets up in the below of rotary driving mechanism 2, ejector beam 5's one end and third rectangular plate 1c fixed connection, ejector beam 5's the other end and first rectangular plate 1a sliding connection, ejector beam 5 keeps away from the one end of first rectangular plate 1a and can slide and run through first rectangular plate 1a and outwards extend.
Based on the above embodiment, when the rotary platform 3 is displaced horizontally, when the rotary platform 3 is displaced to the direction close to the rotary driving mechanism 2, the ejector rod 5 mounted on the mounting bracket 1 ejects out the injection molding part inside the movable mold 4 mounted on the rotary platform 3, so that the injection molding part blanking process is realized, and after the rotary platform 3 is far away from the rotary driving mechanism 2, the ejector rod 5 does not interfere with the rotating function of the rotary platform 3.
The above examples, which are intended to represent only one or more embodiments of the present invention, are described in greater detail and with greater particularity, and are not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
