Description

Forced demoulding mechanism

Technical Field

The utility model relates to a mould manufacturing technical field especially relates to a forced demoulding mechanism.

Background

Referring to fig. 1 and 2, the conventional mold includes:

the front die 1 and the rear die 2 are matched to form a die cavity with the shape matched with that of a target product 7; wherein, one side of the front mould 1 close to the mould cavity is provided with a containing groove;

the inclined elastic block 3 is positioned in the accommodating groove and is in sliding connection with the front die 1;

the spring 4 is positioned on one side, away from the die cavity, of the inclined elastic block 3 and used for driving the inclined elastic block 3 to slide towards the die cavity;

and one end of the fastener 5 is in threaded connection with the inclined elastic block 3, and the other end of the fastener 5 is in sliding connection with the front die 1 so as to limit the inclined elastic block 3 to be separated from the accommodating groove.

The working process of the existing die is as follows:

(1) referring to fig. 1, a front mold 1 and a rear mold 2 are brought close to each other to complete mold assembly; after the die is closed, the rear die 2 overcomes the elastic force of the spring 4 and presses the inclined elastic block 3 into the accommodating groove;

(2) injecting glue solution into the mold cavity, and cooling and solidifying the glue solution to obtain a target product 7;

(3) referring to fig. 2, the front mold 1 and the rear mold 2 are separated from each other to complete the mold opening; specifically, in the mold opening process, as the rear mold 2 gradually moves away from the front mold 1, the inclined elastic block 3 is gradually pushed out of the accommodating groove under the elastic force of the spring 4, and since the inclined elastic block 3 is located on one side of the target product 7 away from the rear mold 2, the inclined elastic block 3 pushes the target product 7 to the rear mold 2, thereby completing the mold opening operation between the target product 7 and the front mold 1.

It should be noted that the existing mold has the following problems:

after repeated mold closing and opening operations are performed for a plurality of times over time, the spring 4 has an obvious fatigue aging phenomenon, which is specifically shown in the situation that the speed of pushing out the inclined elastic block 3 is slow, obvious delay and delay exist during mold releasing, and even the situation that the elastic force is insufficient to push out the inclined elastic block 3, so that the mold releasing between the target product 7 and the front mold 1 fails occurs.

Therefore, the existing mold needs to be improved to solve the problem that the spring is easy to cause mold release delay after aging.

The above information disclosed in this background section is only included to enhance understanding of the background of the disclosure and, thus, may contain information that does not form the prior art that is currently known to those of ordinary skill in the art.
