[0039] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.
[0040] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.
[0041] In this document, ordinal numbers such as “first” and “second” cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order.
[0042] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.
[0043] The utility model provides a molding die. The molding die is used to mold a composite material part. The composite material part includes continuous fibers and thermoplastic materials. The composite material part can be a sheet structure. For example, a sheet of flexible material, or a rigid sheet. The molding mold can mold sheet structures of different widths. The continuous fiber part composed of continuous fibers can enter the molding die through a feed port 121 described later. In the molding die, the continuous fiber part contacts the liquid thermoplastic material. In this way, the thermoplastic material is hot-melt connected to the continuous fiber part to form a composite material part. The composite material part extends out of the molding module through a discharge port 122 described later. In the process of the continuous fiber part entering the molding die and the composite material part leaving the molding die, the molding die can continuously process and mold the composite material part into a long strip structure.
[0044] It should be noted that, during the process of molding composite parts, the size of the feed port 121 and the discharge port 122 mentioned below along the left-right direction D1 is slightly larger than the width of the continuous fiber part, thereby reducing the outflow of liquid thermoplastic material in the molding mold through the feed port 121 and the discharge port 122.
[0045] Please refer to Figure 1 and Figure 2 The molding die includes a body component 110. The body component 110 includes two first components 120 and two second components 130. The second component 130 is a plate. The plane where the second component 130 is located is perpendicular to the up-down direction D3. The two first components 120 are arranged at intervals along the front-back direction D2. The two second components 130 are arranged at intervals along the up-down direction D3. The first first component 120, the first second component 130, the second first component 120 and the second second component 130 are connected end to end in sequence to form a circumferentially closed body annular structure.
[0046] The axial direction of the main body annular structure extends along the left-right direction D1. Thus, the main body annular structure has an inner cavity 111 extending along the left-right direction D1 and an end opening 112. Along the left-right direction D1, the end opening 112 is located at the end of the inner cavity 111 and communicates with the inner cavity 111.
[0047] One of the first component 120 and the second component 130 has a feed port 121 and a discharge port 122. The end opening 112, the feed port 121 and the discharge port 122 are separated in pairs. The feed port 121 and the discharge port 122 are both connected to the internal cavity 111.
[0048] In this way, the continuous fiber piece can enter the internal cavity 111 through the feed port 121 . The continuous fiber piece is hot-melt-connected with the liquid thermoplastic material in the internal cavity 111 to form a composite material piece. The composite material piece extends to the outside of the body component 110 through the discharge port 122 .
[0049] like Figure 1 and Figure 2 As shown, the molding die further includes a blocking member 140. The blocking member 140 blocks the end opening 112 to form a molding space 170. The molding space 170 communicates with the feed port 121 and the discharge port 122. After the continuous fiber piece passes through the feed port 121, it enters the molding space 170 to be hot-melted with the thermoplastic material in the molding space 170 to form a composite material piece. The composite material piece passes through the discharge port 122 from the molding space 170 to leave the molding die. In this way, along the left-right direction D1, the portion of the continuous fiber piece located in the molding die is located in the molding space 170 to be hot-melted with the thermoplastic material in the molding space 170 to form a composite material piece.
[0050] The blocking member 140 is movably arranged along the left-right direction D1. In this way, by moving the blocking member 140 along the left-right direction D1, the position of the blocking member 140 can be changed, thereby changing the size of the molding space 170 along the left-right direction D1. In this way, the blocking member 140 can be moved according to the width size of the continuous fiber piece to be processed along the left-right direction D1, so that the size of the molding space 170 along the left-right direction D1 is slightly larger than the width size of the current continuous fiber piece to be processed, thereby forming a composite material piece in the molding space 170. Therefore, the molding mold can be suitable for molding sheet structures of different width sizes.
[0051] In this embodiment, the blocking member 140 is movably arranged along the left-right direction D1, and the blocking member 140 can be moved according to the width dimension of the continuous fiber part to be processed along the left-right direction D1. In this way, composite material parts of different width dimensions can be formed as needed, and the molding mold can be suitable for molding sheet structures of different width dimensions.
[0052] Optionally, the feed port 121 and the discharge port 122 are respectively located in the two first components 120. Thus, the structure of the body component 110 is simple.
[0053] It is understood that in an embodiment not shown, one of the feed port and the discharge port is located in the first component, and the other of the feed port and the discharge port is located in the second component, or the feed port and the discharge port are located in two second components respectively.
[0054] It should be noted that any two of the left-right direction D1 , the front-back direction D2 , and the up-down direction D3 are perpendicular to each other.
[0055] like Figure 1 As shown, the feed port 121 and the discharge port 122 are both long holes whose long axes are parallel to the left-right direction D1 , so that they can be used to form a sheet structure.
[0056] Alternatively, if Figure 1 and Figure 2 As shown, the second component 130 has a glue inlet 131. The end opening 112, the feed inlet 121 and the discharge port 122 are all separated from the glue inlet 131. The glue inlet 131 is connected to the molding space 170. In this way, liquid thermoplastic material can be continuously injected into the molding space 170 through the glue inlet 131, so that a composite material part with a long length can be continuously processed.
[0057] Furthermore, the glue inlet 131 is located at the upper end of the body component 110. Thus, the structure of the body component 110 is simple.
[0058] Optionally, refer to Figure 1 and Figure 2 , along the left-right direction D1, both ends of the body component 110 are provided with end openings 112. There are two blocking members 140. The two blocking members 140 block the two end openings 112 respectively. Thus, the processing of the molding die is facilitated.
[0059] Furthermore, the blocking member 140 is in a plate shape, so that the structure of the blocking member 140 is simple.
[0060] Optionally, please continue to refer to Figure 1 and Figure 2 One of the first component 120 and the second component 130 has a first guide structure 132 extending in the left-right direction D1. The blocking member 140 has a second guide structure 142. One of the first guide structure 132 and the second guide structure 142 extends into the other.
[0061] Specifically, the second component 130 has a first inner wall surface 113 constituting an internal cavity 111. The first guide structure 132 is configured as a guide groove formed by the depression of the first inner wall surface 113. Both second components 130 have a first guide structure 132. The second guide structure 142 is configured as a guide protrusion extending from the sealing member 140 along the up-down direction D3. The guide protrusion extends into the guide groove. In this way, the first guide structure 132 and the second guide structure 142 cooperate to guide the movement of the sealing member 140 along the left-right direction D1. In addition, the connection strength between the sealing member 140 and the main body assembly 110 is large.
[0062] It can be understood that in an embodiment not shown, the first guide structure can also be provided on the first component.
[0063] Optionally, please continue to refer to Figure 1 and Figure 2 , the first inner wall surface 113 is recessed outwardly away from the center of the internal cavity 111 along the up-down direction D3 to form a first groove 151. The first groove 151 is connected to the glue inlet 131. The blocking member 140 has a second inner wall surface constituting the aforementioned molding space 170. The second inner wall surface is recessed away from the center of the molding space 170 along the left-right direction D1 to form a second groove 152. Along the front-to-back direction D2, the second groove 152 and the first groove 151 are at the same position. In this way, the second groove 152 is connected to the first groove 151 to form an internal groove 150.
[0064] The molding die further includes a blocking member 160. The blocking member 160 is a sheet metal part. The blocking member 160 is located in the internal cavity 111. The blocking member 160 is connected to the blocking member 140 to move together with the blocking member 140. The blocking member 160 covers the opening of the internal slot 150 to separate the internal slot 150 from the feed port 121, and to separate the internal slot 150 from the discharge port 122. The blocking member 160 has an overflow slit 161 connected to the internal slot 150. The width dimension of the overflow slit 161 along the front-to-back direction D2 is smaller than the width dimension of the internal slot 150 along the front-to-back direction D2.
[0065] In this way, the liquid thermoplastic material first enters the internal groove 150 through the glue inlet 131. After filling the internal groove 150, it enters the area where the continuous fiber member is located through the overflow slit 161, thereby contacting the continuous fiber member. In this way, it can be avoided that the liquid thermoplastic material directly impacts the continuous fiber member, thereby causing the thermoplastic material to adhere unevenly to the continuous fiber member. As a result, the strength of the composite material member can be increased.
[0066] Furthermore, if Figure 1 As shown, the blocking member 160 includes a first portion 162 and a second portion 163. The first portion 162 and the second portion 163 are both plate-like structures. The plane where the first portion 162 is located is perpendicular to the up-down direction D3. The plane where the second portion 163 is located is perpendicular to the left-right direction D1. The first portion 162 is connected to the second portion 163. The first portion 162 covers the opening of the first slot 151. The second portion 163 is attached to the second inner wall surface to cover the opening of the second slot 152. As a result, the structure of the blocking member 160 is simple.
[0067] Further, the blocking member 160 includes two first portions 162 and one second portion 163. The two first portions 162 are arranged at intervals along the up-down direction D3. In this way, the two first portions 162 and one second portion 163 are configured as a C-shaped structure. Thus, the strength of the blocking member 160 is large.
[0068] like Figure 1As shown, there are two blocking members 160. The two blocking members 160 correspond to the two blocking members 140 one by one. The second portion 163 of the blocking member 160 is connected to the corresponding blocking member 140. The openings of the C-shaped structures of the two blocking members 160 face each other. The first portions 162 of the two blocking members 160 are partially staggered (on the projection plane perpendicular to the up-down direction D3, the projections of the first portions 162 of the two blocking members 160 partially overlap).
[0069] Furthermore, the first portion 162 has an overflow seam 161 communicating with the first slot 151. Thus, the thermoplastic material of the composite material piece can be made as uniform as possible.
[0070] like Figure 1 As shown, the first slot 151 extends along the left-right direction D1. The sealing member 140 extends and protrudes along the up-down direction D3 to form a slot sealing portion 141. Along the front-to-back direction D2, the position of the slot sealing portion 141 overlaps with the position of the second slot 152. The slot sealing portion 141 extends into the first slot 151. Therefore, in the process of moving the sealing member 140 along the left-right direction D1, the slot sealing portion 141 is always maintained in the first slot 151 to seal the first slot 151 and prevent liquid leakage. In addition, the connection strength between the sealing member 140 and the main body assembly 110 is large. The slot sealing portion 141 and the first slot 151 cooperate to guide the movement of the sealing member 140 along the left-right direction D1.
[0071] Please refer to Figure 1 and Figure 2 , both second parts 130 have a first slot 151. Both blocking members have a second slot 152. In this way, the internal slot 150 is configured as a circumferentially closed slot annular structure. The continuous fiber piece passes through the area surrounded by the slot annular structure of the internal slot 150. In this way, the thermoplastic material of the composite material piece can be made as uniform as possible.
[0072] Furthermore, if Figure 1 and Figure 2 As shown, the first component 120 includes a body 124. The body 124 is a plate. The plane where the body 124 is located is perpendicular to the front-to-back direction D2. Both ends of the body 124 along the up-down direction D3 extend and protrude along the front-to-back direction D2 to form two limiting protrusions 123. The second component 130 is located on the inner side of the limiting protrusion 123. That is, the two second components 130 are located between the two limiting protrusions 123. The two second components 130 are respectively attached to the two limiting protrusions 123. Thereby, the installation of the body assembly 110 is facilitated.
[0073] It can be understood that in the embodiment not shown, the body assembly is constructed as an integrally formed structure.
