[0026] It should be noted that in the related art, the foamed product parts need to be taken out from the foaming mold after the mold is opened. Some one-piece foamed product parts are large in size and have no stress points. It is difficult for workers to demold the foamed product parts smoothly within a unit time, and the foamed product parts may be torn and damaged.

[0027] Based on this, an embodiment of the present application proposes a foaming mold, in which a first groove structure is formed on one side of the first mold body, and a second groove structure is formed on one side of the second mold body. The first groove structure can cooperate with the second groove structure to form a cavity, and the foamed product can be formed in the cavity, thereby achieving the effect of the first mold body and the second mold body being assembled to produce the foamed product. When the foaming mold is placed in an up-and-down direction, the second mold body is located above the first mold body. The embodiment of the present application takes the placement of the foaming mold in an up-and-down direction as an example for explanation. After the foaming mold is opened, the worker disassembles the second mold body, and the foamed product remains in the first mold body. The demolding auxiliary device 1 is arranged on the first mold body, and the demolding auxiliary device 1 can assist the foamed product to be removed from the first mold body.

[0028] The demoulding auxiliary device 1 includes a demoulding disc 11 and a driving unit 12, and the demoulding disc 11 and the driving unit 12 are connected. As an example, the driving unit 12 may include a controller and a pushing cylinder, and the controller may control the pushing shaft of the pushing cylinder to drive the demoulding disc 11 to move, thereby achieving the effect of the driving unit 12 driving the demoulding disc 11 to move. Along the arrangement direction of the first mold body and the second mold body, the driving unit 12 may drive the demoulding disc 11 to move toward or away from the first mold body. When the demoulding auxiliary device 1 assists the foamed product to be released from the first mold body, the driving unit 12 drives the demoulding disc 11 to move away from the first mold body. The driving part 12 is located on the side of the demoulding disc 11 away from the second mold body, that is, the driving part 12 is located below the demoulding disc 11, and the demoulding disc 11 can abut against the foamed product part. The demoulding disc 11 can lift the foamed product part under the drive of the driving part 12, so that the foamed product part can be removed from the first mold body to a certain height, thereby achieving the effect of the demoulding auxiliary device 1 assisting the foamed product part in demoulding, and can reduce the probability of the foamed product part being torn and damaged due to uneven force when the worker takes the foamed product part out of the first mold body, so that the foamed product part can be demoulded smoothly, which is beneficial to improving the production efficiency of the foamed product part.

[0029] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the foaming mold can also include a blowing device 2, which is fixedly connected to the demoulding disk 11 and is located on the side of the demoulding disk 11 away from the second mold body. When the demoulding disk 11 moves, the blowing device 2 is driven to move synchronously, and the blowing device 2 is suitable for blowing toward the foamed product.

[0030] The blowing device 2 is fixedly connected to the demoulding disc 11. The blowing device 2 can be fixedly connected to the demoulding disc 11 by means of clamping, welding, etc. The blowing device 2 is located on the side of the demoulding disc 11 away from the second mold body, that is, the blowing device 2 is located below the demoulding disc 11. When the demoulding disc 11 moves, the blowing device 2 can be driven to move together. When the demoulding disc 11 lifts the foamed product part, the blowing device 2 can blow air toward the foamed product part. The blowing device 2 can further separate the foamed product part from the first mold body by blowing air toward the foamed product part. The blowing device 2 can also separate the part of the foamed product part that is not in contact with the demoulding disc 11 from the first mold body. The demoulding auxiliary device 1 can achieve the effect of pushing the foamed product part out of a certain height of the first mold body before the worker demoulds by working in cooperation with the blowing device 2, thereby reducing the probability of the worker tearing the foamed product part during demoulding, so that the foamed product part can be demoulded smoothly, and the production efficiency of the foamed product part can be improved.

[0031] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the blowing device 2 may include: a plurality of blowing pipes 21, and the plurality of blowing pipes 21 are arranged along the circumference of the demoulding disc 11. By arranging the plurality of blowing pipes 21 along the circumference of the demoulding disc 11, the blowing efficiency of the blowing device 2 can be improved, and the rate of separation of the foamed product from the first mold body can be improved. The blowing device 2 blows air to the foamed product along the circumference of the demoulding disc 11, which can increase the action area of ​​the blowing device 2 on the foamed product, so that multiple positions on the foamed product can be separated from the first mold body in advance under the action of the blowing device 2, which is conducive to improving the demoulding rate of the foamed product.

[0032] In some embodiments of the present invention, a plurality of air blowing pipes 21 are evenly arranged along the circumference of the demoulding disc 11 .

[0033] By evenly arranging multiple blowing pipes 21 along the circumference of the demoulding plate 11, the entire foamed product can be evenly blown, so that the foamed product is evenly subjected to force, reducing local stress and reducing the risk of deformation or damage of the foamed product. Even blowing can also speed up the demoulding speed, which is conducive to improving the production efficiency of the foamed product.

[0034] In some embodiments of the present invention, the blowing pipe 21 includes a first tube body 211 , and the first tube body 211 extends along the radial direction of the demoulding disc 11 to blow air toward the foamed product.

[0035] The central axis of the first tube body 211 is parallel to the surface of the demolding disk 11. The first tube body 211 extends radially along the demolding disk 11 and blows air toward the foamed product, thereby achieving the effect of multiple blowing tubes 21 blowing air on the foamed product and achieving the effect of the blowing tubes 21 separating the foamed product from the first mold body.

[0036] In some embodiments of the present invention, the blowing tube 21 may further include a second tube body 212. The first tube body 211 and the second tube body 212 are connected and communicated with each other, and an angle is formed between the first tube body 211 and the second tube body 212. The second tube body 212 is suitable for communicating with an air source.

[0037] The first tube body 211 is connected to the second tube body 212. The first tube body 211 and the second tube body 212 can be integrally formed. An angle is formed between the first tube body 211 and the second tube body 212. The angle can be a right angle or a right angle. The central axis of the second tube body 212 can be perpendicular to the surface of the demoulding plate 11. The first tube body 211 is connected to the second tube body 212. The second tube body 212 is suitable for connecting with the gas source. The gas can flow from the gas source to the first tube body 211 through the second tube body 212, so as to achieve the effect of the blowing tube 21 blowing air to the foamed product.

[0038] In some embodiments of the present invention, a mounting groove is formed at one end of the first mold body facing the second mold body, the demolding auxiliary device 1 and the blowing device 2 are both installed in the mounting groove, and the outer surface of the demolding plate 11 is coplanar with the surface of the first mold body facing the second mold body.

[0039] In the embodiment of the present application, the mounting groove can be located below the first trough structure, the outer surface of the demoulding disc 11 can be coplanar with the bottom wall of the first trough structure, and the demoulding disc 11 can close the open end of the mounting groove, so as not to affect the molding of the foamed product. The demoulding auxiliary device 1 and the blowing device 2 are both installed in the mounting groove. When the demoulding auxiliary device 1 and the blowing device 2 are not working, the demoulding auxiliary device 1 and the blowing device 2 are both located in the mounting groove to avoid affecting the molding of the foamed product. When the demoulding auxiliary device 1 and the blowing device 2 are working, the driving part 12 drives the demoulding disc 11 to move, and the demoulding disc 11 moves and drives the blowing pipe 21 to move together. The demoulding disc 11 lifts the foamed product to a certain height, and the blowing pipe 21 blows air to the foamed product to further separate the foamed product from the first mold body, thereby achieving the effect that the demoulding auxiliary device 1 and the blowing device 2 work together to push the foamed product to a certain height, so that the foamed product is separated from the first mold body before the worker demolds.

[0040] In some embodiments of the present invention, the foaming mold may further include a guide member 3 , which is fixed in the mounting groove and cooperates with the blowing device 2 in a guiding manner.

[0041] The guide member 3 is fixed in the installation groove. The guide member 3 can be fixedly connected to the side wall and / or bottom wall of the installation groove by welding, bolt connection, etc. A plurality of avoidance holes can be formed on the guide member 3, and the plurality of avoidance holes can extend along the arrangement direction of the first mold body and the second mold body. A plurality of second tube bodies 212 can be penetrated by the plurality of avoidance holes, and each avoidance hole is respectively arranged in a one-to-one correspondence with each second tube body 212. The inner wall of the avoidance hole can be abutted against the second tube body 212 for limiting, and each avoidance hole can play a guiding and limiting role for the corresponding second tube body 212, thereby achieving the guiding and cooperating effect of the guide member 3 and the blowing device 2, reducing the probability of the blowing device 2 being offset during movement, and improving the working safety of the blowing device 2.

[0042] In some embodiments of the present invention, the demoulding disc 11 is circular, and the diameter of the demoulding disc 11 is Φ, satisfying the relationship: Φ≥10mm.

[0043] The cross-sectional shape of the demoulding disc 11 can be circular. For example, the diameter of the demoulding disc 11 can be 10 mm, 12 mm, 15 mm, etc. The diameter of the demoulding disc 11 can be greater than 10 mm. Any value, including the endpoint value, is the diameter of the demoulding disc 11 that can be selected in the present invention. If the diameter of the demoulding disc 11 is less than 10 mm, the contact area between the demoulding disc 11 and the foamed product part is small. When the demoulding disc 11 lifts up the foamed product part, the local stress is too large, which may cause the foamed product part to deform or be damaged. Therefore, setting the diameter of the demoulding disc 11 to be greater than 10 mm can increase the contact area between the demoulding disc 11 and the foamed product part, reduce the probability of the foamed product part being torn due to excessive local stress, and improve the success rate of demoulding the foamed product part.

[0044] In addition, the demoulding disc 11 is arranged on the first mold body, and the outer surface of the demoulding disc 11 is coplanar with the bottom wall of the first mold body. The outer surface of the demoulding disc 11 can be arranged at a flat position on the bottom wall of the first mold body, and the diameter of the demoulding disc 11 cannot be greater than the smallest side at the flat position on the bottom wall of the first mold body. Multiple demoulding auxiliary devices 1 can be arranged, as long as the demoulding auxiliary devices 1 are arranged at a flat position on the bottom wall of the first mold body. Arranging multiple demoulding auxiliary devices 1 is conducive to improving the demoulding efficiency of the foamed product.

[0045] In some embodiments of the present invention, the moving distance of the demoulding plate 11 is H, which satisfies the relationship: 1mm≤H≤3mm.

[0046] The demoulding plate 11 pushes out the foamed production part by moving a certain distance upward, so as to separate the foamed production part from the first mold body before the worker demoulds. Exemplarily, the moving distance of the demoulding plate 11 can be 1mm, 1.6mm, 2.2mm, 3mm, etc. The moving distance of the demoulding plate 11 can be between 1mm and 3mm. Any value including the endpoint value is the moving distance of the demoulding plate 11 that can be selected in the embodiment of the utility model. If the moving distance of the demoulding plate 11 is less than 1mm, the foamed production part may not be separated from the first mold body before the worker demoulds, and the worker may still tear or damage the foamed production part when demoulding, affecting the production efficiency of the foamed production part. If the moving distance of the demoulding plate 11 is greater than 3mm, when the blowing air of the blowing pipe 21 is not delivered to the foamed product part, the moving distance of the demoulding plate 11 is too large, which may cause partial tearing of the foamed production part, affecting the production efficiency of the foamed production part. Therefore, the moving distance of the demoulding plate 11 is in the range of 1mm to 3mm, and the foamed product parts can be pushed out 1mm-3mm before the workers demould, so that the foamed production parts can be demoulded smoothly, thereby improving the production efficiency of the foamed production parts.
