Description

Technical Field

[0001] This utility model belongs to the field of magnetic tile production technology, and in particular relates to a magnetic tile mold demolding device. Background Technology

[0002] Demolding is a crucial step in the production of magnetic tiles. However, existing magnetic tile mold demolding technologies have significant problems, especially during demolding, where the magnetic tiles tend to stick to the inner cavity of the lower mold, causing considerable production difficulties.

[0003] Specifically, due to the magnetic properties of the magnetic tiles, after injection molding, the tiles often exhibit strong adhesion to the inner wall of the lower mold during the cooling and solidification process. During demolding, this adhesion makes it difficult to remove the magnetic tiles smoothly from the lower mold. Operators often need to apply significant external force or use specialized demolding tools to separate the magnetic tiles from the mold. This process is not only time-consuming and labor-intensive but also significantly reduces production efficiency.

[0004] More seriously, the magnetic tiles are easily damaged due to the external forces applied during the demolding process. Scratches, cracks, or even breakage may appear on the surface, severely impacting product quality and yield. Furthermore, damaged tiles require secondary processing or disposal, undoubtedly increasing production costs and wasting resources.

[0005] Therefore, how to overcome the problem that magnetic tiles are easily adsorbed into the inner cavity of the lower mold and are difficult to remove during demolding, and how to avoid damage to the magnetic tiles during the demolding process, have become the core issues that urgently need to be solved in the demolding technology of magnetic tile molds. Utility Model Content

[0006] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0007] A magnetic tile mold demolding device includes:

[0008] A mold, the mold comprising an upper mold and a lower mold;

[0009] The pressure equalization mechanism includes a cavity and a pressure relief channel opened on the side of the lower mold. The cavity penetrates the side wall of the lower mold and a matching plug rod is movably inserted inside it. One end of the pressure relief channel is connected to the outside, and the other end is connected to the end of the cavity near the inner cavity of the lower mold.

[0010] The elastic pusher is connected to a blocking rod located at one end outside the lower mold. When the upper and lower molds are closed, the elastic pusher pushes the blocking rod into the through cavity and blocks the pressure relief channel. When the mold is separated, the blocking rod retracts elastically, and at this time the pressure relief channel and the through cavity are connected.

[0011] As a preferred embodiment of the above technical solution, the demolding device further includes a connecting member, which includes an upper connecting plate fixedly connected to the top of the upper mold and a lower connecting plate fixedly connected to the bottom of the lower mold.

[0012] As a preferred embodiment of the above technical solution, the upper mold is provided with injection holes.

[0013] As a preferred embodiment of the above technical solution, when the elastic pusher pushes the plug rod into the through cavity, one end of the plug rod located inside the lower mold is flush with the mold cavity of the lower mold.

[0014] As a preferred embodiment of the above technical solution, the elastic pusher includes a connecting block with one end of the blocking rod fixed to the outside of the lower mold;

[0015] A vertical plate is fixedly connected to the top of the lower plate, and a spring is fixedly connected between the vertical plate and the connecting block;

[0016] A pressure plate is fixedly connected to the bottom of the upper plate.

[0017] As a preferred embodiment of the above technical solution, the connecting block is provided with a ramp, and the ramp is directly opposite the pressure plate; when the mold is closed, the upper plate drives the pressure plate to descend and block the ramp, thereby pushing the blocking rod into the cavity; when the mold is separated, the spring elastically pulls back the connecting block and the blocking rod.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention's magnetic tile mold demolding device effectively solves the problem of magnetic tiles easily adhering to the lower mold cavity and being difficult to remove during demolding through a cleverly designed pressure-equalizing mechanism and elastic pusher. It also prevents damage to the magnetic tiles during the demolding process. After mold closing and injection molding, the elastic pusher pushes the blocking rod into the through cavity and blocks the pressure relief channel, creating a closed space inside the mold, which facilitates uniform cooling and solidification of the magnetic tiles. During demolding, the blocking rod retracts elastically under the action of a spring, connecting the pressure relief channel to the through cavity, achieving pressure balance between the inside and outside of the mold. This reduces the adhesion force between the magnetic tiles and the inner wall of the lower mold, allowing the magnetic tiles to be easily removed from the mold. This process not only improves production efficiency but also ensures product quality and yield of the magnetic tiles, significantly reducing production costs and resource waste.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example

[0026] The magnetic tile mold demolding device of this utility model specifically includes the following key parts:

[0027] Mold components:

[0028] Upper mold 21: As the upper part of the mold, it is designed with injection holes for injecting molten magnetic tile material into the mold cavity.

[0029] Lower mold 22: As the lower half of the mold, it cooperates with the upper mold 21 to form a complete mold cavity for the molding of magnetic tiles.

[0030] Pressure equalization mechanism:

[0031] Cavity 37: Opened on the side of the lower mold 22, penetrating the side wall of the lower mold 22. Its dimensions match the plug rod 33 to ensure that the plug rod 33 can move smoothly within it.

[0032] Pressure relief channel 34: One end is connected to the inner cavity of the cavity 37 near the lower mold 22, and the other end is connected to the outside. It is used to balance the pressure inside and outside the mold during demolding.

[0033] Blocking rod 33: It is movably inserted into the through cavity 37 and is used to block the pressure relief channel 34 when the mold is closed, forming a closed space, which is conducive to the uniform cooling and curing of the magnetic tile.

[0034] Flexible pusher:

[0035] Connecting block 32: Fixed to one end of the plug rod 33 located outside the lower mold 22, used to connect the plug rod 33 and the spring 36.

[0036] Vertical plate 31: Fixedly connected to the top of the lower plate 12, serving as a fixing point for the spring 36.

[0037] Spring 36: Connected between vertical plate 31 and connecting block 32, it provides elastic thrust so that the blocking rod 33 can be inserted into the through cavity 37 and block the pressure relief channel 34 when the mold is closed, and can be elastically retracted when the mold is opened.

[0038] Pressure plate 35: Fixedly connected to the bottom of the upper plate 11, it is designed with an inclined surface that matches the ramp 321 on the connecting block 32. During mold closing, the pressure plate 35 descends and abuts against the ramp 321, pushing the connecting block 32 and the blocking rod 33 to move.

[0039] Ramp 321: It is provided on the connecting block 32 and is used to cooperate with the pressure plate 35 to realize the pushing and retraction of the blocking rod 33.

[0040] Connector:

[0041] Upper plate 11: Fixedly connected to the top of the upper mold 21, used to connect and support the upper mold 21.

[0042] Lower plate 12: Fixedly connected to the bottom of the lower mold 22, used to connect and support the lower mold 22.

[0043] Working principle:

[0044] When the mold is closed, the upper mold 21 and the lower mold 22 fit tightly together, and the injection hole is used to inject molten magnetic tile material. At the same time, the upper connecting plate 11 drives the pressure plate 35 to descend. The pressure plate 35 abuts against the ramp 321, pushing the connecting block 32 and the blocking rod 33 to move, so that the blocking rod 33 is inserted into the through cavity 37 and blocks the pressure relief channel 34, forming a closed space.

[0045] After the magnetic tile material cools and solidifies, during mold separation, the spring 36 elastically pulls back the connecting block 32 and the blocking rod 33. At this time, the pressure relief channel 34 and the through cavity 37 are connected, the pressure inside and outside the mold is balanced, and the magnetic tile can be easily removed from the mold.

[0046] It should be noted that when the spring 36 pulls the plug rod 33 back to its original position in this utility model, there is a certain resistance under atmospheric pressure because the inner cavity of the lower mold 22 is filled with magnetic tiles. Therefore, the spring 36 in this utility model is selected with a large elastic coefficient. In actual applications, an elastic coefficient of 100 N / cm is selected. In this embodiment, the distance between the pressure relief channel 34 and the inner cavity of the lower mold 22 is 3 mm. Therefore, the plug rod 33 only needs to be pulled back by 3 mm to balance the air pressure.

[0047] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
