Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of an assembly of a mold in a demolding device according to an embodiment of the present invention, and fig. 2 is a schematic view of a structure of the demolding device according to an embodiment of the present invention; the present embodiment provides a demolding device 200, wherein the demolding device 200 can improve the demolding efficiency and ensure the demolding quality, and comprises a frame 210 and a demolding assembly 220.

It should be noted that the demolding device 200 includes, but is not limited to, demolding application of the PU mold 100.

Specifically, referring to fig. 1-3, fig. 3 is a schematic structural view of a demolding assembly and a positioning assembly according to an embodiment of the present invention; the frame 210 of the demolding apparatus 200 is used to mount the mold 100; the demolding assembly 220 is movably connected to the frame 210, the demolding assembly 220 includes a first abutting portion 221 and a second abutting portion 222 for abutting against the mold 100, in the mold opening direction of the mold 100, the height of the first abutting portion 221 is higher than that of the second abutting portion 222, and the demolding assembly 220 is configured to be movable relative to the frame 210 along the mold opening direction of the mold 100 under the action of an external force, so as to open the mold 100.

The mold 100 mounted on the frame 210 is in a mold to be clamped state. In addition, the mold 100 includes two opposite ends, which may be an open end and a closed end, and during the demolding process, the principle is to fix one end of the mold and drive the other end to move relative to the fixed end to realize the demolding effect, so that when the mold 100 is installed, the open end or the closed end needs to be fixed relative to the mounting frame, and the other end needs to be supported against the demolding assembly 220.

According to the present embodiment, the operation principle of the mold-releasing device 200 is as follows:

as can be seen from the above description, to complete the demolding of the mold 100, the demolding device 200 includes a frame 210 and a demolding assembly 220, and both ends of the mold 100 are respectively connected to the frame 210 and the demolding assembly 220, and then the demolding assembly 220 is driven by an external force to move relative to the frame 210 along the mold opening direction, so as to complete the demolding of the mold 100. However, in the process of demolding, since the interior of the mold 100 is under negative pressure after the colloid is molded, the interior has a certain absorption force under the negative pressure condition, and thus, the resistance of the demolding assembly 220 moving along the demolding direction is increased in the process of demolding.

Therefore, in order to improve the demolding efficiency of the mold 100 and avoid damage to the mold 100 due to excessive external force during the demolding process, when the demolding assembly 220 is provided to abut against the mold 100 to drive the abutting portion of the mold 100 to move along the mold opening direction, the height of the first abutting portion 221 may be set to be higher than the height of the second abutting portion 222 in the mold opening direction of the mold 100. With such an arrangement, in the demolding process, a certain height difference H1 exists between the first abutting portion 221 and the second abutting portion 222 of the demolding assembly 220, so that the contact time between the first abutting portion 221 and the mold 100 is inconsistent with the contact time between the second abutting portion 222 and the mold 222. Therefore, in the process that the demolding assembly 220 drives the mold 100 to move along the mold opening direction, since the height of the first abutting portion 221 is greater than that of the second abutting portion 222, that is, the second abutting portion 222 is relatively close to the mold 100, during demolding, along with the movement of the demolding assembly 220, the second abutting portion 222 can contact with the mold 100 before the first abutting portion 221, so that a local stress is formed at a contact portion between the mold 100 and the second abutting portion 222, at this time, an acting force between the demolding assembly 220 and the mold 100 is not uniform and is not symmetrical, so that a contact portion between the mold 100 and the second abutting portion 222 is locally deformed, after the deformation occurs, external air can enter a molding cavity of the mold 100, and the pressure inside the mold 100 is consistent with the outside, so that the demolding resistance in the demolding process can be reduced, and then after the first abutting portion 221 contacts with the mold 100, the mold 100 can be quickly released without changing the external force for moving the releasing assembly 220.

The present embodiment provides a mold release device 200 with at least the following advantages:

based on the above, it can be seen that the demolding device 200 can reduce the steps of demolding operation and the difficulty of demolding operation on the premise of reducing the overall structure of the device, thereby improving the demolding efficiency. In the demolding process, the demolding quality can be improved, and meanwhile, the damage to the mold 100 can be prevented, so that the service life of the mold 100 can be prolonged, and the use cost of the mold 100 can be reduced.

Further, referring to fig. 1 and fig. 2, in the present embodiment, in order to movably connect the demolding assembly 220 with the frame 210, so that the demolding assembly 220 can move in the mold opening direction relative to the frame 210 under the action of an external force and complete the demolding of the mold 100, the demolding device 200 further includes a connecting member 230. When the connecting member 230 is disposed, the connecting member 230 may include a positioning plate 231, a movable plate 232 and a guide post 233.

The positioning plate 231 is connected to the frame 210, and defines a moving space for opening the mold 100 together with the frame 210, so that when the positioning plate 231 is disposed, a certain distance needs to be kept between the positioning plate 231 and the frame 210 for installing the mold 100, and the distance is greater than the maximum height of the mold 100 in the mold opening direction.

The movable plate 232 is used for mounting the mold release assembly 220, the movable plate 232 is movably connected with the positioning plate 231 through the guide posts 233, and the guide posts 233 are used for guiding the movable plate 232 to move along the mold opening direction.

Further, referring to fig. 3, in order to improve the demolding efficiency of the demolding device 200, when the connecting member 230 is disposed, the demolding assembly 220 can be automatically reset after the mold opening of the mold 100 is completed, and therefore, the connecting member 230 further includes a limiting member 234 for limiting the movement of the movable plate 232 in the mold opening direction.

When the limiting member 234 is disposed, the limiting member 234 is a limiting spring, the limiting spring is located between the movable plate 232 and the positioning plate 231, and two ends of the limiting spring are respectively abutted against the movable plate 232 and the positioning plate 231, so that the movable plate 232 has a tendency of moving along the mold closing direction, and after the mold opening of the mold 100 is completed, the movable plate 232 can automatically return to a position matched with the mold 100 in the mold closing state on the frame 210 after the external force disappears.

Further, referring to fig. 1-3, the demolding device 200 may further include a positioning assembly 240 detachably disposed on the frame 210, on the basis of the demolding assembly 220. The positioning assembly 240 includes a first positioning portion 241 and a second positioning portion 242 for abutting against the mold 100; the first positioning portion 241 has a height higher than that of the second positioning portion 242 in the mold opening direction of the mold 100, and the positioning assembly 240 is used for mounting the mold 100 on the frame 210. Note that, when the first positioning portion 241 and the second positioning portion 242 of the positioning assembly 240 are provided, the operation principle and the achievable technical effect of the height difference H2 between the two portions are consistent with the operation principle and the achievable technical effect of the height difference H1 between the first abutting portion 221 and the second abutting portion 222 in the mold release assembly 220, and therefore, the detailed description thereof is omitted.

Further, referring to fig. 1 and fig. 2, in order to improve the demolding efficiency of the demolding device 200, the demolding device 200 further includes a power assembly 250, and the power assembly 250 may be an air cylinder. The power assembly 250 is used for driving the demolding assembly 220 to move, so that the demolding assembly 220 has a first position and a second position relative to the frame 210.

It should be noted that, when the power assembly 250 is provided, the power assembly 250 may be disposed on the positioning plate 231 and be in transmission connection with the movable plate 232 so as to drive the demolding assembly 220 mounted on the movable plate 232 to move when the movable plate 232 is driven to move.

When the demolding assembly 220 is in the first position, the demolding assembly 220 may be configured to cooperate with the mold 100 in the mold clamping state, that is, the demolding assembly 220 in the first position may cooperate with the mold 100 in the mold clamping state, so that two ends of the mold 100 in the mold opening direction cooperate with the demolding assembly 220 and the positioning assembly 240, respectively.

And when the stripper assembly 220 is in the second position, the stripper assembly 220 is adapted to cooperate with the mold 100 in the open mold position. It should be noted that the first abutting portion 221 and the second abutting portion 222 of the demolding assembly 220 at this position can cooperate with the mold 100 in the mold opening state, so that the demolding assembly 220 can drive the mold 100 to change from the mold closing state to the mold opening state in the process of moving from the first position to the second position, i.e. complete the mold opening operation of the mold 100. It should be noted that, as can be seen from the above, in the present embodiment, the connection member 230 includes a limiting spring, and the demolding assembly 220 located at the second position can have a tendency to move toward the first position through the limiting spring, so as to improve the returning efficiency of the demolding assembly 220.

Furthermore, when the demolding assembly 220 and the positioning assembly 240 of the demolding device 200 are provided, in order to enable the demolding assembly 220 and the positioning assembly 240 to be matched with the mold 100 for mold opening, the interval between the first abutting portion 221 and the second abutting portion 222 and the interval between the first positioning portion 241 and the second positioning portion 242 need to be adapted to the size of the mold 100. Similarly, in order to enable the demolding device 200 to be used for demolding molds 100 of different sizes, the application range of the demolding device 200 can be further expanded by adjusting the interval between the first abutting portion 221 and the second abutting portion 222 on the movable portion and the interval between the first positioning portion 241 and the second positioning portion 242 on the frame 210.
