Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative work, all belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a technical solution: a medical injection mold convenient for demolding comprises a mold 1, wherein the mold 1 is a medical injection mold; the die base plate 2 is arranged at the bottom of the die 1, and is vertically connected with the die 1 in a sliding manner;
the cross section of the die base plate 2 is matched with the middle die cavity of the die 1, and the die base plate 2 is connected with the inner wall of the die 1 in a sealing mode.
The four corners below of the die base plate 2 are fixedly connected with the top of the spring 21, and the bottom of the spring 21 is fixedly connected with the four corners below the die cavity of the die 1.
And the sliding block 3 is fixedly arranged in the middle of the lower part of the die bottom plate 2, and is clamped and fixed with the bottom of the die 1.
The lower middle part fixedly connected with slider 3 of bottom plate 2, the vertical sliding connection in middle part below of slider 3 and mould 1, the left and right sides of slider 3 are provided with the spout, and horizontal sliding connection has locating pin 4 in the spout, and the outside end of locating pin 4 is fixed with the 11 joints of mould 1 middle part both sides draw-in groove.
The inner end of the positioning pin 4 is fixedly connected with the outer end of the positioning spring 41, and the inner end of the positioning spring 41 is fixedly connected with the inner wall of the slide block 3.
The middle part of the inner side of the positioning pin 4 is fixedly connected with the outer side end part of the connecting rope 42, and the inner side end part of the connecting rope 42 penetrates through the middle part of the sliding block 3 and is fixedly connected with the middle parts of the left side and the right side of the ball block 5.
The working principle is as follows: after the injection molding and cooling of the material in the cavity of the mold 1 are completed, the rotating rod 51 is rotated to rotate the ball block 5.
The connection ropes 42 at both sides are twisted by the rotation of the ball 5, so that the outer sides of the connection ropes 42 at both sides are retracted inward.
And the positioning pins 4 at the two sides are pulled to be contracted into the two sides of the sliding block 3, so that the sliding of the sliding block 3 at the middle part below the die 1 is not obstructed.
At this time, the spring 21 gives an upward elastic force to the die base plate 2, so that the die base plate 2 is vertically ejected upward, and the object is ejected upward out of the die 1, thereby completing the demolding of the object.
After the object is demoulded, the die base plate 2 is pressed downwards, so that the die base plate 2 slides vertically downwards.
Until the outer lower parts of the two side positioning pins 5 contact the inner wall of the bottom of the die 1, the rotating rod 51 is rotated again to contract the two side positioning pins 4.
At this time, the rotating rod 51 is continuously pulled downwards, so that the slide block 3 slides downwards to the lower middle part of the mold 1, and the positioning pin 4 is aligned with the clamping groove 11.
Under the action of the elastic force of the positioning spring 41, the positioning pin 4 horizontally pops out and is inserted into the clamping groove 11, and the sliding block 3 and the die 1 are fixed for the next injection molding.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
