Multiple connecting buckles 101 are integrally formed on both side walls of the secondary instrument body 10. The connecting buckles 101 are provided with a first buckle groove 102, a second buckle groove 103, and a third buckle groove 104 that are interconnected. The third buckle groove 104 is located on the side of the first buckle groove 102 away from the opening of the second buckle groove 103. During automobile assembly, these three buckles are used to cooperate with the buckles of other automobile parts.

[0003] The secondary instrument panel body 10 is injection molded. In the mold of the secondary instrument panel body 10, the molding block used to form the second groove 103 needs to move along the mold opening direction. This movement direction causes the molding block used to form the second groove 103 to collide with the molding block used to form the side wall of the secondary instrument panel body 10 during demolding, making it impossible for them to avoid each other. Therefore, a special mold structure needs to be designed so that the molding block used to form the second groove 103 and the molding block used to form the side wall of the secondary instrument panel body 10 can avoid each other and not interfere with each other when the mold opens.

[0017] By adopting the technical scheme, before the second forming block moves out of the second buckle groove, the second control mechanism controls the third forming block to move into the second forming block, so that the third forming block does not collide with the connecting buckle when moving out of the second buckle groove, thereby preventing the connecting buckle from being deformed and reducing the risk of the connecting buckle being broken when the second forming block moves out of the second buckle groove.

Subsequently, along with the movement of the second forming block and the first forming block, the second inclined surface and the third inclined surface are no longer in abutment, and the second inclined surface abuts against the fourth inclined surface, because the inclination of the fourth inclined surface is greater than that of the third inclined surface, so that when the first forming block and the second forming block move synchronously, the space formed after the movement of the fourth inclined surface is greater than the space required for the movement of the matching block along with the second forming block, and the difference between the spaces enables the third forming block to move into the first installation cavity and drive the matching block to move.

DETAILED DESCRIPTION

[0041] The application will be further described in detail below with reference to the accompanying drawings, so that the technical scheme of the present application is easier to understand and master.

[0042] Referring to Figures 4-6 , the injection mold for injection molding the lower body of the auxiliary instrument of the automobile of the embodiment comprises an upper fixed plate 11, a hot runner plate 12, a fixed mold plate 13, a movable mold plate 14, two mold feet 15, and a lower fixed plate 16. The upper fixed plate 11, the hot runner plate 12, and the fixed mold plate 13 are connected with each other to form an upper mold body, and the movable mold plate 14, the two mold feet 15, and the lower fixed plate 16 are connected with each other to form a lower mold body.

[0043] Referring to Figure 5 , Figure 7 and Figure 8 , two sliders one 2 are connected to the movable mold plate 14 along the direction perpendicular to the mold opening direction, and the two sliders one 2 are symmetrically arranged on the movable mold plate 14 and are respectively used for forming the sidewalls of the two sides of the auxiliary instrument main body 10. The slider one 2 comprises a first block 23 and a second block 24 which are connected with each other. An avoiding groove 22 is formed on one side of the second block 24 which is connected with the first plate body 51, and the first block 23 blocks the opening of the avoiding groove 22. A mounting plate 5 is connected in the avoiding groove 22 along the direction perpendicular to the mold opening direction, and the mounting plate 5 comprises a first plate body 51 and a second plate body 52 which are connected with each other, and the second plate body 52 is located on the side of the first plate body 51 close to the first block 23.

[0044] Referring to Figure 5 , Figure 7 and Figure 8The second plate 24 has through slots 25 on both side walls that communicate with the clearance slots 22. The two ends of the two first plates 51 extend out of the corresponding sliders 2 through the four through slots 25. Four fixing blocks 8 are detachably connected to the moving template 14. The ends of the two first plates 51 extending out of the second plate 24 are inserted into the corresponding fixing blocks 8. The two first plates 51 and the two second plates 52 are stationary relative to the moving template 14.

[0045] Reference Figure 5 , Figure 7 and Figure 8 The moving template 14 is equipped with two sets of first control mechanisms 3 for controlling the two sliders 2 respectively. The first control mechanism 3 includes a pressing surface 31 on the end of the second block 24 away from the first block 23, and multiple first springs 32 mounted on the second plate 52. The multiple first springs 32 all pass through the first plate 51 and abut against the sliders 2. The elastic force of the multiple first springs 32 acts on the sliders 2. When the mold opens, the multiple first springs 32 drive the sliders 2 away from the auxiliary instrument body 10. When the mold closes, the fixed template 13 presses against the two pressing surfaces 31 to drive the two second blocks 24 to move closer to each other and compress the multiple first springs 32.

[0046] Reference Figure 5 , Figures 7-12 On the side of the two first blocks 23 that are close to each other, there are multiple forming areas 21 for forming connecting buckles 101. The forming areas 21 are provided with forming blocks 4 for forming the first buckle groove 102. Multiple inclined top seats 6 are installed on the second plate 52. The inclined top seats 6 are provided with inclined top rods 7. The ends of the inclined top rods 7 penetrate the second block 24 and extend into the forming areas 21. When the first block 23 moves away from the auxiliary instrument body 10, it pushes against the inclined top rods 7 to drive the inclined top rods 7 to move closer to the moving template 14.

[0047] Reference Figure 12 The end of the inclined push rod 7 includes a second molding block 91 for forming the second groove 103 and a third molding block 92 for forming the third groove 104. The second molding block 91 has an installation cavity 93. The third molding block 92 is connected in the installation cavity 93 along the mold opening direction perpendicular to the mold. The second molding block 91 is provided with a second control mechanism 95. The second control mechanism 95 can control the third molding block 92 to slide into the second molding block 91 and slide out of the second molding block 91.

[0048] Reference Figure 12The forming block two 91 is provided with an installation cavity two 94, the second control mechanism 95 includes a rod body one 951, a second spring 952 provided in the installation cavity two 94 and an abutting block 953, a matching block 954 slidingly connected in the installation cavity one 93 along the opening direction of the mold, a first inclined surface 955 and a second inclined surface 956 provided on the matching block 954, a third inclined surface 957 and a fourth inclined surface 958 provided on the forming block one 4. One end of the rod body one 951 extends into the installation cavity one 93 and is connected with the forming block three 92, the other end of the rod body one 951 extends into the installation cavity two 94 and is threadedly connected with the abutting block 953, the second spring 952 is sleeved on the rod body one 951 and abuts against the abutting block 953, the elastic force of the second spring 952 acts on the abutting block 953, and the second spring 952 always drives the abutting block 953 to move away from the installation cavity one 93. The cavity opening of the installation cavity two 94 is plugged with a copper plug after the second spring 952 and other components are installed.

[0049] With reference to Figures 12-14 The first inclined surface 955 and the second inclined surface 956 are respectively arranged at the top and the bottom of the matching block 954, the first inclined surface 955 is in abutment with the forming block three 92, and the forming block two 91 moves into the forming block three 92 to abut against the first inclined surface 955, thereby driving the matching block 954 to move close to the bottom wall of the installation cavity one 93. The forming block one 4 extends into the installation cavity one 93, the second inclined surface 956 is in abutment with the third inclined surface 957, the second inclined surface 956 and the third inclined surface 957 have the same inclination, and the inclination of the fourth inclined surface 958 is greater than that of the third inclined surface 957. When the forming block one 4 moves into the installation cavity one 93, the fourth inclined surface 958 abuts against the forming block, thereby driving the matching block 954 to move away from the bottom wall of the installation cavity one 93.

[0050] With reference to Figures 12-14 The injection molding steps of the mold of the application are as follows:

[0051] First, the injection molding machine is operated to control the mold to close, so that the movable mold plate 14 moves close to the fixed mold plate 13, and in this process, the fixed mold plate 13 abuts against the two abutting surfaces 31, so that the two first blocks 23 and the two second blocks 24 move close to each other. When the two second blocks 24 move close to each other, the plurality of inclined jacks 7 are driven to reset, so that the plurality of forming blocks two 91 and the plurality of forming blocks three 92 respectively move into the plurality of forming areas 21. At the same time, when the two second blocks 24 move close to each other, the plurality of first springs 32 are also abutted, so that the plurality of first springs 32 are compressed under stress.

[0052] During the process that the third forming block 92 moves into the forming area 21 following the second forming block 91, the fourth inclined surface 958 of the first forming block 4 will press against the matching block 954 to drive the matching block 954 to slide away from the bottom wall of the installation cavity one 93. When the matching block 954 slides away from the bottom wall of the installation cavity one 93, the first inclined surface 955 will drive the third forming block 92 to move out of the installation cavity one 93, so that the third forming block 92 finally abuts against the first forming block 4, thereby preparing for the forming of the third buckle groove 104. When the third forming block 92 moves out of the installation cavity one 93, the rod body one 951 will drive the abutting block 953 to move close to the installation cavity one 93, so that the second spring 952 is compressed under stress.

[0053] After the mold is completely closed, the injection molding machine injects hot melt plastic into the mold, and the hot melt plastic will flow into the forming cavity between the fixed mold plate 13 and the movable mold plate 14, thereby completing the injection molding of the auxiliary instrument body 10. After the injection molding of the auxiliary instrument body 10 is completed, the injection molding machine controls the mold to open, so that the movable mold plate 14 moves away from the fixed mold plate 13.

[0054] With the separation of the fixed mold plate 13 and the movable mold plate 14, the fixed mold plate 13 will gradually cancel the pressure on the two pressing surfaces 31, at which time the multiple first springs 32 on the two installation plates 5 will rebound to drive the two second blocks 24 to move away from each other, and the two second blocks 24 will move away from each other, thereby driving the two first blocks 23 to move away from the auxiliary instrument body 10.

[0055] During the process that the two first blocks 23 move away from each other, the first forming block 4 will move away from the first buckle groove 102, and the multiple inclined ejector rods 7 will move close to the movable mold plate 14. At the same time, a cavity will be formed between the two first blocks 23 and the auxiliary instrument body 10, thereby providing sufficient movement space for the inclined ejector rods 7 and the second forming block 91, so that the inclined ejector rods 7 and the second forming block 91 will not collide with the sliding block one 2 when they move close to the movable mold plate 14.

[0056] When the inclined ejector rods 7 move close to the movable mold plate 14, the second forming block 91 and the third forming block 92 will move close to the movable mold plate 14 together with the inclined ejector rods 7, thereby causing the second forming block 91 and the third forming block 92 to move out of the connecting buckle 101.

[0057] In the process of the movement of the forming block one 4 and the forming block two 91, the range of the second inclined surface 956 and the third inclined surface 957 is getting smaller and smaller. Subsequently, with the movement of the forming block two 91 and the forming block one 4, the second inclined surface 956 and the third inclined surface 957 are no longer in contact, and the matching block 954 is in contact with the fourth inclined surface 958. Subsequently, with the continuous movement of the forming block one 4 and the forming block two 91, the second spring 952 can gradually rebound and drive the abutting block 953 to move away from the installation cavity one 93. When the abutting block 953 moves away from the installation cavity one 93, it will drive the forming block three 92 to move into the installation cavity one 93 through the rod body one 951. When the forming block three 92 moves into the installation cavity one 93, it will press the first inclined surface 955 to drive the matching block 954 to move close to the bottom wall of the installation cavity one 93, and press the matching block 954 on the fourth inclined surface 958. Before the forming block one 4 completely moves out of the installation cavity one 93, the forming block three 92 will completely move into the installation cavity one 93, and the matching block 954 will also move to the position closest to the bottom wall of the installation cavity one 93 on its movement path.

[0058] When the forming block three 92 moves into the forming block two 91, it will make the forming block three 92 move out of the second buckle groove 103 without colliding with the connecting buckle 101. Thus, the connecting buckle 101 will not be deformed, and the risk of breaking of the connecting buckle 101 when the connecting forming block two 91 moves out of the second buckle groove 103 is reduced. After the mold is completely opened, the auxiliary instrument main body 10 can be taken out of the mold. After the auxiliary instrument main body 10 is taken out of the mold, the injection molding machine controls the mold to close again, and starts the injection molding of the next auxiliary instrument column body.

[0059] Of course, the above is only a typical example of the present application, in addition to which, the present application can have other various specific embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
