DETAILED DESCRIPTION

[0028] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0032] In order to facilitate the subsequent understanding of this solution, the structure of the existing one-piece injection molding of the airbag can be described below. A specific example is as follows: Figure 1 and Figure 2 As shown, the airbag includes a plastic shell 01, a plurality of metal inserts 02 and a mesh 03. The specific number of metal inserts 02 can be determined according to actual installation requirements, for example Figure 1 and Figure 2 As shown, there are six metal inserts 02, and the six metal inserts 02 are evenly arranged along the side of the plastic shell 01. That is, on the rectangular end face of the plastic shell 01, two metal inserts 02 are symmetrically installed on the two long sides, and one metal insert 02 is installed in the middle of the two short sides. The mesh 03 is injection molded in the plastic shell 01 in the shape of a "J". Specifically, the middle area of ​​the mesh 03 is injection molded in the end face of the plastic shell 01, and the bending areas on both sides of the mesh 03 are injection molded on the side of the cavity corresponding to the two long sides of the plastic shell 01.

[0033] In order to realize the one-time injection molding of the above-mentioned product, one of the preferred embodiments of the present application is as follows: Figure 3 and Figure 4As shown, a mold for integrated injection molding of mesh and inserts includes a movable mold 200, a fixed mold 100, and a positioning mechanism 3. A cavity for injection molding a plastic shell 01 can be formed between the movable mold 200 and the fixed mold 100 by closing the mold. In the open mold state, the metal insert 02 to be injected can be inserted into the corresponding position of the movable mold 200, and the mesh 03 to be injected can be placed in the corresponding position of the movable mold 200. The positioning mechanism 3 is installed on the movable mold 200. After the mesh 03 is placed, the positioning mechanism 3 can bend and position the two sides of the mesh 03; and then when closing the mold, the cavity formed between the fixed mold 100 and the movable mold 200 can cover the metal insert 02 and the mesh 03, and the mesh 03 can be evenly distributed in the cavity. At the same time, when the fixed mold 100 and the movable mold 200 are closed, the mesh 03 can also be tensioned between the fixed mold 100 and the movable mold 200 through the tensioning structure; and then after the injection molding of the cavity is completed, the metal insert 02 and the mesh 03 can be stably injection molded into the molded plastic shell 01 to form the required airbag product.

[0034] It can be understood that this embodiment places the metal insert 02 and the mesh 03 in the mold cavity at the same time, and then realizes the molding of the airbag product through one-time injection molding of a single mold. Compared with traditional multiple molding of multiple molds, it can effectively improve the production efficiency and molding accuracy of the airbag product.

[0035] It should be known that, for the metal insert 02, the uncoated area on the product is an optical axis structure, so when performing injection molding of the airbag product, it is only necessary to insert the optical axis section of the metal insert 02 into the mold, and then the coated area of ​​the metal insert 02 corresponding to the airbag product will be exposed in the mold cavity, so that when the plastic shell 01 is subsequently injected, the coated area of ​​the metal insert 02 can be directly injected into the plastic shell 01 to achieve a coated connection. For the mesh 03, since the mesh 03 is a flexible structure, in order to ensure that the mesh 03 can be stably injected into the plastic shell 01, the mesh 03 needs to be shaped and tensioned. Among them, the shaping of the mesh 03 needs to be achieved through the positioning mechanism 3, that is, the positioning mechanism 3 can first bend and position the mesh 03 according to the injection shape of the mesh 03, and then during the clamping process of the fixed mold 100 and the movable mold 200, the mesh 03 is tensioned through the tensioning structure, thereby ensuring that the mesh 03 is stably tensioned and injection-molded in the plastic shell 01.

[0036] It should also be known that if the mesh 03 is directly placed at the corresponding position of the movable mold 200, since the mesh 03 has a certain ductility, the two sides of the mesh 03 may remain parallel to the end surface of the movable mold 200 or be slightly bent, which will make it difficult for the positioning mechanism 3 to position and press the two sides of the mesh 03. Therefore, before the positioning mechanism 3 performs the bending and positioning of the two sides of the mesh 03, it is necessary to pre-bend the two sides of the mesh 03, and then the positioning mechanism 3 bends and positions the two sides of the mesh 03 after the pre-bending. In more popular terms, by pre-bending the two sides of the mesh 03, when the positioning mechanism 3 squeezes the two sides of the mesh 03, the two sides of the mesh 03 can be bent according to the traces of the pre-bending to determine the trajectory; that is, the pre-bending can provide trajectory assistance for the subsequent bending positioning. There are two main ways to pre-bend the mesh 03. For the convenience of understanding, a specific analysis will be conducted below.

[0037] In the first pre-bending method, the movable mold 200 is provided with a shaping core 21 for supporting the mesh 03, and the mesh 03 has been bent before the mesh 03 is placed on the shaping core 21. That is, the mesh 03 is always placed in a state where both sides are bent, and then when the mesh 03 is placed on the shaping core 21, both sides of the mesh 03 are in a bent state close to the movable mold 200, so that the positioning mechanism 3 can be directly started to bend and position both sides of the mesh 03.

[0038] The second pre-bending method, such as Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, a shaping core 21 for supporting the mesh 03 is provided on the movable mold 200. The mesh 03 is placed on the shaping core 21 in the mold opening state, and then the two sides of the mesh 03 extending out of the shaping core 21 are bent by the robot 04, so that the positioning mechanism 3 moves from a position far away from the shaping core 21 to approach and bend the two sides of the bent mesh 03 to position.

[0039] It is understandable that, for the first pre-bending method mentioned above, when the mesh 03 is placed on the shaping core 21, the bending degree of both sides of the mesh 03 is uncertain or uncontrollable, which may cause the positioning mechanism 3 to be unable to bend and position both sides of the mesh 03. Therefore, in this embodiment, the pre-bending of both sides of the mesh 03 preferably adopts the second pre-bending method mentioned above; for ease of understanding, the pre-bending process can be described in detail below.

[0040] In the mold opening state, first Figure 8 As shown in (1), the mesh cloth 03 in a natural state is placed on the molding surface of the shaping core 21; Figure 6 and Figure 7As shown, the positioning mechanism 3 is away from the shaping core 21 to ensure that there is enough pre-bending space on both sides of the mesh 03. Figure 8 As shown in (2), the two sides of the mesh 03 are bent close to the movable mold 200 by the manipulator 04; then the manipulator 04 keeps bending the mesh 03 and starts the positioning mechanism 3 to approach the shaping core 21, and then when the positioning mechanism 3 contacts and squeezes the bent positions on both sides of the mesh 03, the manipulator 4 can be away from the mesh 03 to avoid interference with the positioning mechanism 3. Fig. 9 As shown, when the positioning mechanism 3 moves to a set position close to the shaping core 21 , both sides of the mesh 03 are bent and pressed and positioned by the positioning mechanism 3 .

[0041] It is understandable that the specific structure and working principle of the robot 04 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here.

[0042] In this embodiment, there are many specific structures of the positioning mechanism 3 that can achieve the above functions. For the sake of easy understanding, the following will be described in detail using one of the structures. Figure 3 , Figure 4 , Figure 6 and Fig. 9 As shown, two positioning mechanisms 3 are provided and are relatively arranged on both sides of the cavity. The positioning mechanism 3 includes a movable core 32 and a telescopic device 31; the movable core 32 is slidably mounted on the movable mold 200, and the telescopic device 31 is fixedly mounted on the movable mold 200 and connected to the side of the movable core 32 away from the fixed core 21 through the output end, so that the movable core 32 can slide along the movable mold 200 close to the fixed core 21 under the drive of the telescopic device 31, and then the two sides of the mesh 03 can be bent and positioned.

[0043] It is understandable that the side of the moving core 32 close to the fixed core 21 can be used as a part of the cavity, and can also be used to bend and press the curved position of the mesh 03. The specific structure and working principle of the telescopic device 31 are well-known technologies for those skilled in the art, so they are not elaborated in detail here; common telescopic devices 31 include linear motors, cylinders, and hydraulic cylinders.

[0044] It should be noted that, since the bending lengths of the two sides of the mesh 03 are different, when the mesh 03 is placed on the molding surface of the shaping core 21, the extension lengths of the two sides of the mesh 03 are different, and the mesh 03 may be offset during the pre-bending or bending positioning process, which may result in the unqualified injection molding of the mesh 03. Therefore, when placing the mesh 03, the mesh 03 needs to be limited by a limiting structure.

[0045] In this embodiment, Figures 2 to 4 as well as Figure 7 and Figure 8 As shown, the shaping core 21 is provided with a through hole 212, and the movable mold 200 is provided with a positioning rod 22 that can penetrate the through hole 212 on the shaping core 21. The mesh 03 is provided with a positioning hole 031, so that when the mesh 03 is placed, the mesh 03 can be placed on the shaping core 21 through the positioning hole 031 and the positioning rod 22 to form a limiting structure.

[0046] It should be known that the number of the positioning holes 031 provided on the positioning rod 22 and the mesh 03 can be one or more. In order to improve the bending stability of the mesh 03, the number of the positioning holes 031 provided on the positioning rod 22 and the mesh 03 is preferably multiple, for example Figure 2 and Figure 4 As shown, the number of the positioning holes 031 opened on the positioning rod 22 and the mesh 03 is four.

[0047] It is understandable that when the mesh 03 is placed on the shaping core 21 through the limited cooperation of the positioning rod 22 and the positioning hole 031, for the pre-bending of the mesh 03, the force applied by the manipulator 04 to the mesh 03 will drive the mesh 03 to stretch to both sides, and then the middle area of ​​the mesh 03 will remain tensioned. However, when the manipulator 04 is away from the mesh 03 and is bent and positioned by the positioning mechanism 3, the force applied by the positioning mechanism 3 to the mesh 03 will drive both sides of the mesh 03 to move toward the middle, that is, the middle area of ​​the mesh 03 located on the shaping core 21 will be in a relaxed state, and then when the plastic shell 01 is subsequently injection molded, the middle area of ​​the mesh 03 may be injected into the plastic shell 01 in the form of wrinkles, so that the quality of the airbag product may not meet the use requirements; therefore, when the movable mold 200 and the fixed mold 100 are molded, the mesh 03 needs to be tensioned by the tensioning structure.

[0048] In this embodiment, Figure 5 and Fig.11 As shown, the non-molding areas on both sides of the molding surface of the fixed core 21 are provided with grooves 210; the fixed mold 100 is provided with corresponding protrusions 110. When the movable mold 200 and the fixed mold 100 are molded, the protrusions 110 can be matched with the grooves 210 to form a tensioning structure, and then the tensioning structure can stretch the mesh 03 so that the rest of the mesh 03 is tensioned.

[0049] It should be known that the cooperation of the groove 210 and the protrusion 110 can increase the support area of ​​the shaping core 21 supporting the mesh 03, and then the wrinkles in the middle of the mesh 03 and the mesh 03 itself are tensioned and deformed to compensate for the increase in the support area, thereby achieving tensioning of the mesh 03. Due to the positioning cooperation of the positioning rod 22 on the mesh 03, the shaping surface of the shaping core 21 is provided with grooves 210 on both sides of the perforation 212 to achieve tension compensation on both sides of the middle of the mesh 03.

[0050] It is understandable that the protrusion 110 may also be provided on the fixed core 21 , and the groove 210 may be provided on the fixed mold 100 .

[0051] In this embodiment, if the protrusion 110 is directly set on the fixed mold 100, the processing of the protrusion 110 is difficult due to the large structural size of the fixed mold 100. Therefore, the protrusion 110 can be set by inserting; Fig.11 As shown, a fixed mold insert 11 is installed on the fixed mold 100, and a protrusion 110 is arranged at the end of the fixed mold insert 11. In theory, the structure of the protrusion 110 and the groove 210 only needs to increase the support length of the mesh 03, but in order to avoid shear damage to the mesh 03 caused by the cooperation of the protrusion 110 and the groove 210, the protrusion 110 and the groove 210 can both adopt an arc structure.

[0052] In this embodiment, for the insertion of the metal insert 02, the hole can be directly inserted on the movable mold 200, and then the metal insert 02 can be directly inserted into the movable mold 200; however, considering that the structure size of the movable mold 200 is large, it is not convenient to process the hole; therefore, the insertion method can be used to realize the setting of the hole. Figure 4 , Figure 7 and Fig.10 As shown, a movable mold insert 23 is installed on the movable mold 200 , and a socket is provided on the movable mold insert 23 , and the metal insert 02 to be injected can be plugged into the socket on the movable mold insert 23 .

[0053] In this embodiment, the movable mold insert 23 can be directly installed on the movable mold 200. However, considering the injection position of the metal insert 02, if the movable mold insert 23 is directly installed on the movable mold 200, the fixed core 21 may interfere with the removal of the movable mold insert 23; and when the movable mold insert 23 fails or wears out and needs to be replaced, the fixed core 21 needs to be removed before the movable mold insert 23 can be removed. If the movable mold insert 23 is installed on the fixed core 21, when the movable mold insert 23 needs to be replaced, the movable mold insert 23 can be directly removed. Specifically, Figure 5 , Figure 7 and Fig.10As shown, a mounting groove 211 is provided on the fixed core 21 , and the movable mold insert 23 is installed in the mounting groove 211 .

[0054] It should be known that the specific number of the movable mold inserts 23 is equal to the number of the metal inserts 02 to be injected. According to the injection position of the metal inserts 02, when the movable mold core 32 is close to the fixed mold core 21 to perform the bending and positioning of the mesh 03, Fig.10 As shown, the moving core 32 can avoid the metal insert 02 through the avoidance groove 320 opened at the end.

[0055] In this embodiment, in order to ensure the injection molding stability of the metal insert 02, the metal insert 02 needs to be interference fit or transition fit with the socket, which may result in a large adhesive force between the metal insert 02 and the socket when the product is demoulded, and forced separation may cause the connection between the metal insert 02 and the plastic shell 01 to be unstable. Therefore, in order to ensure the injection molding stability and smooth demoulding of the metal insert 02, the metal insert 02 can be movably plugged into the socket and magnetically adsorbed with the movable mold 200. That is, the socket only needs to position the metal insert 02, and then the magnetic force generated by the magnetic adsorption restricts the movement of the metal insert 02 in the direction of detaching from the socket, thereby ensuring the stability of the metal insert 02 during the injection molding process, and after the injection molding is completed, its demoulding force is basically equal to the magnetic force of the magnetic adsorption.

[0056] In this embodiment, the magnetic adsorption of the metal insert 02 can be achieved by the provided magnetic block 231. The magnetic block 231 can be directly installed on the movable mold 200, but considering the structural size of the movable mold 200, it is difficult to process the installation cavity for fixing the magnetic block 231; Fig.10 As shown, the magnetic block 231 can be set at the bottom of the movable mold insert 23 and facing the insertion hole. After the metal insert 02 is inserted into the insertion hole, it can be magnetically adsorbed to the magnetic block 231, and the magnetic force generated by the magnetic block 231 on the metal insert 02 coincides with the axial direction of the metal insert 02, so that the metal insert 02 can be axially pressed against the movable mold insert 23 to further improve the injection molding stability of the metal insert 02.

[0057] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
