Description

Technical Field

[0001] This application relates to the field of liquid silicone, and more specifically to a liquid silicone extraction device. Background Technology

[0002] Liquid silicone is relatively soft, and after the injection and curing process is completed in the mold, it is usually demolded manually. For some enclosed products, especially some long and thin products, there will be a vacuum adsorption between the outer side and the inner side of the mold, making it difficult to demold. The manual demolding method is also very cumbersome and laborious, resulting in extremely low production efficiency and high labor intensity for workers.

[0003] There are devices on the market that use air blowing to demold liquid silicone. However, demolding by blowing may have the following problems: if the air in the air compressor is not clean, air bubbles may appear inside or on the surface of the product, which will affect the quality of the product; if the air output from the air compressor is not sufficiently filtered or dried, residual oil, moisture and other contaminants may adhere to the mold surface, resulting in uncured surface or local defects in the product.

[0004] Therefore, improvements are needed to the existing liquid silicone extraction equipment. Utility Model Content

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] One preferred embodiment of this application, such as Figures 1 to 3 As shown, a liquid silicone removal device includes a frame 1, a demolding assembly 2, and a drive assembly 3. A mold 4 for producing silicone products is placed on the frame 1, the drive assembly 3 is installed on the frame 1, and the demolding assembly 2 is installed on the drive assembly 3. The drive assembly 3 is adapted to drive the adsorption end of the demolding assembly 2 to extend into the inner side of the silicone product in the mold 4, thereby separating the silicone product from the inner wall of the cavity 410 of the mold 4 by adsorbing it with negative pressure. The demolding assembly 2 is adapted to clamp the outer side of the separated silicone product with its clamping end, thereby driving the silicone product to detach from the mold 4 under the drive of the drive assembly 3.

[0029] It should be noted that after the liquid silicone is injected and cured in the mold 4, it usually needs to be manually pulled out by hand. This makes the process of injecting and curing the liquid silicone very cumbersome and laborious. It takes about one minute to remove a silicone product, resulting in extremely low production efficiency and high labor intensity for workers.

[0030] Compared to traditional solutions, the advantages of this solution are that it includes a demolding component 2 and a driving component 3. The demolding component 2 can be connected to the driving component 3. The driving component 3 can drive the demolding component 2 to move. When the driving component 3 drives the demolding component 2 to a certain position, the demolding component 2 can shrink the product. At the same time, the demolding component 2 can also clamp the outside of the product and drive the product to move under the drive of the driving component 3, so that the product and the mold 4 can be demolded.

[0031] In this embodiment, as Figure 3 As shown, the mold 4 includes a cover 40 and a cavity 41; the cavity 41 is connected to the frame 1; the cover 40 is installed above the cavity 41 to close the cavity 41; when the cover 40 is detached from the cavity 41, the demolding assembly 2 is adapted to be inserted into the cavity 41 to demold the product.

[0032] It should be noted that the liquid silicone is injected and cured within the mold 4; therefore, a cavity 410 is provided on the cavity 41.

[0033] To facilitate understanding, the workflow of mold 4 will be explained in detail below.

[0034] When glue injection is required, first separate the cover 40 and the cavity 41 so that the cavity 410 provided on the cavity 41 is exposed to the outside, and then inject glue into the cavity 410.

[0035] After the glue injection is completed, the cover 40 is reinstalled on top of the cavity 41 so that the cover 40 can seal the cavity 410.

[0036] When demolding the liquid silicone, firstly, the cover 40 and cavity 41 are separated, exposing the liquid silicone after injection curing to the outside. Then, the drive assembly 3 is activated, which drives the demolding assembly 2 to move. When the suction end of the demolding assembly 2 is inserted into the product, the demolding assembly 2 drives the liquid silicone to shrink through negative pressure suction. At this time, the liquid silicone is only separated from the cavity 410, but the liquid silicone is still inside the cavity 410. After the liquid silicone shrinks, the demolding assembly 2 clamps the outside of the liquid silicone. After clamping the liquid silicone, the drive assembly 3 drives the demolding assembly 2 to move, detaching the liquid silicone from the cavity 410.

[0037] In this embodiment, as Figure 4 As shown, the demolding assembly 2 includes a first demolding component 20 and a second demolding component 21; the adsorption end is disposed on the first demolding component 20; the clamping end is disposed on the second demolding component 21; the first demolding component 20 is fitted and installed on the second demolding component 21; the second demolding component 21 is fitted and installed on the drive assembly 3.

[0038] There are various ways to set up an external pump body; in this embodiment, a standard air suction pump is preferred.

[0039] In this embodiment, as Figure 4 As shown, the first demolding component 20 includes an adsorption head 201; an adsorption end is disposed at one end of the adsorption head 201 to generate negative pressure, and the other end of the adsorption head 201 is adapted to be connected to an external pump body via a hose 200; the adsorption head 201 is adapted to generate negative pressure under the drive of the external pump body; specifically, the first end of the adsorption head 201 is connected to the external pump body via a hose 200; an air hole 2010 is provided on the side of the second end of the adsorption head 201; the adsorption head 201 is adapted to generate negative pressure at the second end under the drive of the external pump body.

[0040] Based on the above, the adsorption end of the adsorption head 201 can be inserted into the inside of the product for adsorption under the drive of the drive component 3. The other end of the adsorption head 201 can be connected to a standard air pump through a hose 200. When the standard air pump is started, the pump body first evacuates air from the hose 200 and the adsorption head 201. The adsorption head 201 is provided with air holes 2010, which are located inside the product. Therefore, the pump body evacuates air from the inside of the product through the air holes 2010, so that the inside of the product is in a negative pressure state, thereby causing the product to shrink. At this time, the outside of the product has separated from the inner wall of the cavity. The second demolding component 21 can clamp the outside of the product and can drive the product out of the mold 4 under the drive of the drive component 3.

[0041] As can be seen from the above, the second demolding component 21 can clamp the outer side of the product; therefore, in this embodiment, as Figure 4 As shown, the second demolding component 21 includes a cylinder 210 and a pair of clamping members 211; the cylinder 210 is fitted to the drive assembly 3; the pair of clamping members 211 are fitted to the cylinder 210; the cylinder 210 is adapted to drive the pair of clamping members 211 to move in opposite directions to clamp the product.

[0042] It is understood that the first demolding component 20 is fitted onto the second demolding component 21; in this embodiment, to facilitate the installation of the first demolding component 20, such as Figure 4 As shown, the demolding assembly 2 is also provided with a mounting part 22; the mounting part 22 is adapted to be fixedly connected with the cylinder 210, and the first demolding part 20 can be connected with the mounting part 22, so that the drive assembly 3 can drive the first demolding part 20 to move by driving the second demolding part 21.

[0043] In this embodiment, the configuration of the driving component 3 is particularly important; the driving component 3 needs to be able to stably drive the demolding component 2 to move; therefore, regarding the configuration of the driving component 3, in this embodiment, as follows: Figure 5As shown, the drive assembly 3 includes a motor 30, a lead screw 31, and a connecting block 32; the lead screw 31 is fitted to the output end of the motor 30; the connecting block 32 is fitted to the lead screw 31; the demolding assembly 2 is fitted to the connecting block 32; the motor 30 is adapted to rotate by driving the lead screw 31 to drive the connecting block 32 to move the demolding assembly 2.

[0044] Specifically, the motor 30 is started, and the lead screw 31 is installed at the output end of the motor 30, so that the lead screw 31 rotates under the drive of the motor 30; the connecting block 32 is adapted to be screwed with the lead screw 31 so that the lead screw 31 can drive the connecting block 32 to move by rotating; the demolding component 2 is installed on the connecting block 32, so that the drive component 3 can drive the demolding component 2 to move.

[0045] In this embodiment, to facilitate the installation of the motor 30 and the lead screw 31, such as Figure 5 As shown, the drive assembly 3 is also provided with a mounting base 33; the motor 30 is adapted to be fixedly mounted on the mounting base 33; the lead screw 31 is adapted to be rotatably connected to the mounting base 33; the mounting base 33 can be fixedly connected to the frame 1 to ensure the installation stability of the motor 30 and the lead screw 31.
