[0038] An implementation method of the present application is described in detail below with reference to the accompanying drawings.

[0039] The first implementation method:

[0040] The present invention provides a demoulding device for molding new material products. Figure 1-8 , including a fixed support 1, a forming mold base 2 and a demoulding mechanism 3.

[0041] Among them, Figure 1 As shown, a plurality of molding die holders 2 are provided, and the plurality of molding die holders 2 can be combined to form a molding cavity of a new material product.

[0042] Likewise Figure 1 As shown, a plurality of demoulding mechanisms 3 are provided, and a plurality of molding die bases 2 are provided in one-to-one correspondence with a plurality of demoulding mechanisms 3 , and the molding die bases 2 are installed on the inner side of the fixed support 1 through the demoulding mechanisms 3 .

[0043] Regarding the demoulding mechanism 3, specifically, Figure 2 , Figure 3 and Figure 4 It is shown that the demoulding mechanism 3 includes an electric push rod 31, an auxiliary movable seat 32, a leading component and a trailing component. The electric push rod 31 is installed on the fixed support 1, and the output end of the electric push rod 31 is fixed to the auxiliary movable seat 32. The leading component includes a clutch structure and a molding module 37. The molding module 37 is installed on the auxiliary movable seat 32 through the clutch structure. The molding die base 2 is provided with a demoulding through hole 201 for the molding module 37 to slide through. When a plurality of molding die bases 2 are combined to form a molding cavity of a new material product, the end of the molding module 37 away from the auxiliary movable seat 32 and the end face of the molding die base 2 away from the auxiliary movable seat 32 are located on the same plane, and the trailing component is installed between the molding die base 2 and the auxiliary movable seat 32.

[0044] The demolding device for molding new material products is provided with a plurality of molding die seats 2. After molding is completed, the electric push rod 31 drives the auxiliary movable seat 32 to open outward with the leading component first, so that the molding module 37 is separated from the surface of the molded product. Then, under the cooperation of the clutch structure and the rear component, the molding module 37 stops moving, and the electric push rod 31 drives the auxiliary movable seat 32 to open outward with the molding die seat 2 through the rear component until the molded product contacts the molding module 37 again, and under the limiting action of the molding module 37, the molding die seat 2 is separated from the surface of the molded product. At this time, the demolding operation is completed without manual intervention, and the demolding efficiency is higher.

[0045] In addition, the plurality of molding die seats 2 open outwardly directly perpendicular to the surface of the molded product, and are not prone to friction with the surface of the molded product, thereby ensuring the demoulding quality of the molded product.

[0046] Among them, regarding the clutch structure, specifically, Figure 3 and Figure 4 As shown, the clutch structure includes an elastic puller 33 and a first limiting push rod 34. The elastic puller 33 is installed between the auxiliary movable seat 32 and the molding module 37. The first limiting push rod 34 is fixed to the side end of the fixed support 1 close to the molding die seat 2. The auxiliary movable seat 32 is provided with a clearance slide hole 3202 for the first limiting push rod 34 to slide through. The first limiting push rod 34 is used to limit the molding module 37.

[0047] The elastic puller 33 includes a limit plate 332 and a tension spring 334 . The limit plate 332 is fixed to the end of the molding module 37 close to the auxiliary movable seat 32 . The tension spring 334 is fixed between the auxiliary movable seat 32 and the limit plate 332 .

[0048] In addition, the elastic puller 33 also includes a limiting sleeve 331 and a limiting slide 333. The limiting sleeve 331 is fixed on the auxiliary movable seat 32. The limiting slide 333 is fixed to the limiting plate 332 and is slidably sleeved on the inner side of the limiting sleeve 331. The tension spring 334 is fixed between the limiting slide 333 and the limiting sleeve 331.

[0049] Regarding the rear-moving component, specifically, the rear-moving component includes a first L-shaped tie rod 202 fixed to the side of the forming mold base 2 close to the auxiliary movable seat 32, a second L-shaped tie rod 3201 fixed to the side of the auxiliary movable seat 32 close to the forming mold base 2, and an elastic limiting structure installed between the fixed support 1 and the first L-shaped tie rod 202. The first L-shaped tie rod 202 is adapted to the second L-shaped tie rod 3201. When a plurality of forming mold bases 2 are combined to form a forming mold cavity of a new material product, the first L-shaped tie rod 202 is not in contact with the second L-shaped tie rod 3201.

[0050] Further, regarding the elastic limiting structure, specifically, the elastic limiting structure includes a second limiting push rod 35 and a compression spring 36. The second limiting push rod 35 is fixed to the side of the fixed support 1 close to the forming mold base 2. The auxiliary movable seat 32 is provided with a second clearance slide hole 3203 for the second limiting push rod 35 to slide through. The compression spring 36 is fixed between the first L-shaped pull rod 202 and the second limiting push rod 35.

[0051] Based on the coordination setting of the above structure, when the electric push rod 31 drives the auxiliary movable seat 32 to start moving outward, the auxiliary movable seat 32 opens outward with the molding module 37 through the elastic pull member 33, so that the molding module 37 is separated from the surface of the molded product; then the electric push rod 31 drives the auxiliary movable seat 32 to continue to move outward. At this time, the limiting plate 332 cannot continue to open outward with the molding module 37 due to the limiting action of the first limiting push rod 34. At the same time, the auxiliary movable seat 32 pulls the first L-shaped pull rod 202 outward through the second L-shaped pull rod 3201, so that the molding mold base 2 opens outward until the molded product contacts the molding module 37 again, and under the limiting action of the molding module 37, the molding mold base 2 is separated from the surface of the molded product, and the demolding operation is completed at this time.

[0052] It should be further explained that the final outward opening distance of the molding die base 2 is sufficient to allow the molded product to be taken out.

[0053] Among them, the set tension spring 334 is used to ensure that the auxiliary movable seat 32 can be smoothly opened outward with the molding module 37 through the elastic puller 33, and its tensioning effect is used to ensure that the molding module 37 will not separate from the auxiliary movable seat 32 during the later movement of the molding mold base 2; the compression spring 36 can ensure that the molding mold base 2 will not move synchronously with the molding module 37 during the process of the auxiliary movable seat 32 opening outward with the molding module 37, thereby ensuring that the molding module 37 can smoothly separate from the surface of the molded product.

[0054] A guide slide bar 203 is fixed to the end surface of the forming die base 2 close to the auxiliary movable base 32 , and a guide slide hole 101 is provided on the fixed support 1 for the guide slide bar 203 to slide through, thereby ensuring the stable opening and closing action of the forming die base 2 .

[0055] Among them, the end surfaces of the molding die base 2 and the molding module 37 away from the auxiliary movable base 32 are coated with a non-stick coating; demoulding is more convenient and the quality of the finished product is better.

[0056] Working principle: When the electric push rod 31 drives multiple molding mold bases 2 to approach each other to form a molding mold cavity for a new material product, conventional molding operations of the new material product can be carried out, such as injection molding (an injection molding port (not shown in the figure) is reserved on the molding mold base 2 located on the uppermost side for injection molding). After the product is formed, when the electric push rod 31 drives the auxiliary movable seat 32 to start moving outward, the auxiliary movable seat 32 opens outward with the molding module 37 through the elastic pull member 33, so that the molding module 37 is separated from the surface of the molded product; then the electric push rod 31 drives the auxiliary movable seat 32 to continue to move outward. At this time, the limit plate 332 cannot continue to open outward with the molding module 37 under the limiting action of the first limiting push rod 34. At the same time, the auxiliary movable seat 32 pulls the first L-shaped pull rod 202 outward through the second L-shaped pull rod 3201, so that the molding mold base 2 opens outward until the molded product contacts the molding module 37 again, and under the limiting action of the molding module 37, the molding mold base 2 is separated from the surface of the molded product, and the demolding operation is completed at this time.

[0057] Compared with the prior art, the present solution sets a plurality of molding die seats 2. After molding is completed, the electric push rod 31 drives the auxiliary movable seat 32 to open outward with the leading assembly first, so that the molding module 37 is separated from the surface of the molded product. Then, under the cooperation of the clutch structure and the rear assembly, the molding module 37 stops moving, and the electric push rod 31 drives the auxiliary movable seat 32 to open outward with the molding die seat 2 through the rear assembly until the molded product contacts the molding module 37 again. Under the limiting action of the molding module 37, the molding die seat 2 is separated from the surface of the molded product. At this time, the demoulding operation is completed without manual intervention, and the demoulding efficiency is higher.

[0058] Compared with the prior art, the present solution sets a plurality of molding die seats 2. After molding, the plurality of molding die seats 2 are directly opened outward perpendicularly to the surface of the molded product, and are not prone to friction with the surface of the molded product, thereby ensuring the demolding quality of the molded product.

[0059] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
