Embodiment Construction
[0020] refer to figure 1 to Figure 4 As can be seen:
[0021] The present invention comprises: core template 1, core pulling device 2, sliding frame 33, such as figure 2 shown.
[0022] The core template 1 is a plate for fixing the core mold, which is a rectangular plate, the middle part of which is provided with a core mold positioning hole 14, and the hole wall of the core mold positioning hole is provided with an annular boss 18 connecting the core mold. Screw holes 13 are provided on the boss, and the mandrel enters the mandrel positioning hole 14 from the front of the core formwork 1 to connect with the boss, and is fixed with screws. Guide post hole is used for passing core-pulling guide post 19, locks core-pulling guide post by core-pulling lock 117, as figure 2 , image 3 shown.
[0023] The core pulling device 2 is a device for locking and opening the mandrel. The mold of the bellows socket is composed of a semicircular upper mold and a semicircular lower ...

The invention relates to a core drawing mechanism of a bellows birthmouth injection machine. The core drawing mechanism comprises a mandrel plate, a core drawing device and a sliding frame, the mandrel plate is a rectangular plate, the central portion of the mandrel plate is provided with a mandrel positioning hole, and four corners of the mandrel plate are respectively provided with a core drawing guide pillar hole; the core drawing device is composed of four core drawing oil cylinders, four core drawing guide pillars and four core drawing locks, the core drawing oil cylinders are fixed on the core drawing guide pillar holes at the left and right sides of the front panels of the upper template and the lower template of a film locking mechanism, and the core drawing guide pillars are horizontally arranged in a sagittal mode; and the sliding frame is a rectangular frame, a frame pedestal is arranged below the sliding frame, and a slide rail is arranged between the frame pedestal and the sliding frame. The core drawing mechanism has the advantages of very convenient entry locking and drawing of the mandrel, high stability, easy product quality guarantee, and convenience for the maintenance, dismounting and mounting of a die.
Description
technical field [0001] The invention relates to a core-pulling mechanism of an injection molding machine with a bellows socket. Background technique [0002] The corrugated pipe of the injection molding machine in the prior art is generally connected by heating and reaming one end of the corrugated pipe. Due to the reaming, the pipe wall at the reaming part becomes thinner and the strength decreases; Uniform heating, low processing efficiency. Contents of the invention [0003] The object of the present invention is to provide a core-pulling mechanism for an injection molding machine with bellows sockets, aiming at the defects of the prior art. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A core-pulling mechanism for an injection molding machine with a bellows socket, which is characterized in that it includes: a core template, which is a rectangular plate, with a core mold positioning hole in the middle, ...
