Description

Technical Field

[0001] The present invention relates to the field of molds, and in particular to an in-situ forming block synchronous demolding injection mold for injecting the lower body of an automotive co-driver instrument panel. Background Art

[0002] An automotive co-driver instrument panel lower body, as shown in Figure 1 , Figure 2 , Figure 3 , includes a co-driver instrument panel main body 10. A plurality of connecting buckles 101 are integrally formed on both side walls of the co-driver instrument panel main body 10. Among them, a first buckle groove 102, a second buckle groove 103, and a third buckle groove 104 that communicate with each other are formed on the connecting buckle 101. The third buckle groove 104 is located on one side of the notch of the first buckle groove 102 away from the second buckle groove 103. These three buckle grooves are used to cooperate with the buckle parts of other automotive components during vehicle assembly.

[0003] The co-driver instrument panel main body 10 is injection-molded by a mold. In the forming mold of the co-driver instrument panel main body 10, the forming block for forming the second buckle groove 103 needs to move along the mold opening direction. This movement direction will cause the forming block for forming the second buckle groove 103 in the mold to collide with the forming block for forming the side wall of the co-driver instrument panel main body 10 during the demolding process, and it is impossible to achieve the movement avoidance between the two. Therefore, a special mold structure needs to be designed so that the forming block for forming the second buckle groove 103 in the mold and the forming block for forming the side wall of the co-driver instrument panel main body 10 can avoid each other and do not affect each other when the mold is opened. Summary of the Invention

[0004] The present application provides an in-situ forming block synchronous demolding injection mold for injecting the lower body of an automotive co-driver instrument panel. By setting a linkage structure, while ensuring the formation of the connecting buckle, the first slider can also move to avoid the inclined ejector rod.

[0005] The in-situ forming block synchronous demolding injection mold for injecting the lower body of an automotive co-driver instrument panel provided by the present application adopts the following technical solutions: An injection mold for synchronous demolding of an out-of-position forming block for an injection-molded lower body of an automotive passenger-side instrument panel, including a fixed template and a movable template. Two first sliders for forming the side walls of the main body of the passenger-side instrument panel are slidably connected to the movable template, and two groups of first control mechanisms for controlling the first sliders are provided on the movable template. A plurality of forming areas for forming connecting buckles are formed on the first sliders, and a first forming block for forming a first buckle groove is arranged in the forming areas. An avoidance groove is formed in the first sliders, and a mounting plate is connected in the avoidance groove. The end of the mounting plate extends out of the first sliders and is fixed on the movable template. A plurality of inclined ejector seats are arranged on the mounting plate, and inclined ejector rods are arranged on the inclined ejector seats. The end of the inclined ejector rod extends into the forming area and is used for forming a second buckle groove and a third buckle groove. When the first sliders move away from the main body of the passenger-side instrument panel, the inclined ejector rods are driven to move close to the movable template.

[0006] By adopting the above technical solution, after the product is injection-molded, the injection molding machine controls the mold to open. At the same time, the first control mechanism controls the first sliders to move away from the formed main body of the passenger-side instrument panel. When the first sliders move away from the main body of the passenger-side instrument panel, the first forming block is driven to move out of the first buckle groove, releasing the reverse buckle structure between the first forming block and the first buckle groove. At the same time, when the first sliders move away from the main body of the passenger-side instrument panel, a plurality of inclined ejector rods are driven to move close to the movable template, so that the end of the inclined ejector rod moves out of the second buckle groove, thereby releasing the reverse buckle structure between the inclined ejector rod and the second buckle groove and the third buckle groove. When the first sliders move away from the main body of the passenger-side instrument panel, a cavity is formed between the first sliders and the main body of the passenger-side instrument panel, so that there is enough downward movement space for the end of the inclined ejector rod, and the end of the inclined ejector rod will not collide with the first sliders when moving downward.

[0007] Preferably, the first control mechanism includes a pressing surface formed on the first sliders and a plurality of first springs arranged on the mounting plate. The elastic forces of the plurality of first springs act on the first sliders, and the plurality of first springs drive the first sliders to move away from the main body of the passenger-side instrument panel when the mold opens. When the mold is closed, the fixed template presses against the two pressing surfaces to drive the two first sliders to move closer to each other and compress the plurality of first springs.

[0008] By adopting the above technical solution, when the mold is closed, the fixed template presses against the two pressing surfaces to drive the two first sliders to move closer to each other, and the plurality of first springs are compressed by force, completing the movement reset of the two first sliders. When the mold opens, as the fixed template and the movable template separate, the fixed template gradually cancels the pressing against the two pressing surfaces. At this time, the plurality of first springs on the two mounting plates will rebound to drive the two first sliders to move away from the main body of the passenger-side instrument panel.

[0009] Preferably, the mounting plate includes a first plate body and a second plate body connected to each other. The two ends of the first plate body extend out of the first sliders and are fixed on the movable template, and the plurality of inclined ejector seats are all arranged on the second plate body.

[0010] By adopting the above technical solution, the installation of components such as the sliding seat is facilitated.

[0011] Preferably, four fixing blocks are detachably connected to the moving template, and the end of the first plate body extending out of the corresponding first slider is inserted into the fixing blocks.

[0012] By adopting the above technical solution, after the first plate body is assembled into the avoidance groove, two fixing blocks are inserted into the two ends of the first plate body extending out of the corresponding first slider, and then the two fixing blocks are fixed to the moving template with bolts. This installation structure facilitates the assembly and disassembly of the mold.

[0013] Preferably, the first slider includes a first block body and a second block body connected to each other. The avoidance groove is formed in the second block body, and the first block body seals the notch of the avoidance groove; the forming area is formed in the first block body, and the ejector pin penetrates through the second block body and extends into the forming area. When the first plate body moves away from the sub-instrument body, the ejector pin is driven to slide close to the moving template.

[0014] By adopting the above technical solution, the installation of the mounting plate and multiple ejector pins is facilitated.

[0015] Preferably, the end of the ejector pin includes a forming block two for forming the second buckle groove and a forming block three for forming the third buckle groove. An installation cavity one is formed in the forming block two, the forming block three is connected in the installation cavity one, and a second control mechanism for controlling the forming block two is provided on the forming block two.

[0016] By adopting the above technical solution, before the forming block two moves out of the second buckle groove, the second control mechanism controls the forming block three to move into the forming block two, so that the forming block three will not collide with the connecting buckle when it moves out of the second buckle groove, thereby preventing the connecting buckle from deforming and reducing the risk of the connecting buckle breaking when the forming block two moves out of the second buckle groove.

[0017] Preferably, an installation cavity two is formed in the forming block two. The second control mechanism includes a rod one, a second spring arranged in the installation cavity two and a resisting block, a matching block slidably connected in the installation cavity one, a first inclined surface and a second inclined surface arranged on the matching block, and a third inclined surface and a fourth inclined surface arranged on the forming block one. One end of the rod one is connected to the forming block three, and the other end of the rod one is connected to the resisting block. The second spring is sleeved on the rod one and abuts against the resisting block. The second spring always drives the resisting block to move away from the installation cavity one. The forming block one extends into the installation cavity one. The first inclined surface is in fit with the forming block three. The second inclined surface is in fit with the third inclined surface. The slope of the fourth inclined surface is greater than that of the third inclined surface. When the forming block two moves into the forming block three, it presses against the first inclined surface and drives the matching block to approach the bottom wall of the installation cavity one. When the forming block one moves into the installation cavity one, it presses against the matching block and drives the matching block away from the bottom wall of the installation cavity one.

[0018] By adopting the above technical solution, when the mold is opened, the forming block one moves away from the matching block, and the matching block and the forming block three move close to the moving template following the forming block two. During this process, the fitting range of the second inclined surface and the third inclined surface becomes smaller and smaller. Subsequently, with the movement of the forming block two and the forming block one, the second inclined surface and the third inclined surface are no longer in fit, and the second inclined surface is in fit with the fourth inclined surface. Since the slope of the fourth inclined surface is greater than that of the third inclined surface, when the forming block one and the forming block two move synchronously, the space formed after the movement of the fourth inclined surface is larger than the space required for the matching block to move following the forming block two. Then, this space difference enables the forming block three to move into the installation cavity one and drive the matching block to move.

[0019] The technical effects of the present invention are mainly reflected in the following aspects: 1. By setting the linkage structure, while ensuring the formation of the connecting buckle, the slider one can also move to avoid the angled ejector rod; 2. By setting the spring and using the mold opening and closing states to control the slider one; 3. When the mold is opened, the present invention controls the forming block three to move into the forming block two, so that when the forming block three is disengaged from the second buckle groove, it will not collide with the connecting buckle, thereby preventing the connecting buckle from deforming and reducing the risk of the connecting buckle breaking when the forming block two moves out of the second buckle groove.

Detailed implementation manners

[0037] The present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solutions of the present application are easier to understand and master.

[0038] Refer to Figures 4 - 6 , a synchronous demolding injection mold with an out-of-position forming block for injecting the lower body of an automotive auxiliary instrument in this embodiment, includes an upper fixing plate 11, a hot runner plate 12, a stationary mold plate 13, a moving mold plate 14, two mold feet 15, and a lower fixing plate 16. Among them, the upper fixing plate 11, the hot runner plate 12, and the stationary mold plate 13 are connected to form an upper mold body, and the moving mold plate 14, the two mold feet 15, and the lower fixing plate 16 are connected to form a lower mold body.

[0039] Refer to Figure 5 , Figure 7 and Figure 8 , two first sliders 2 are slidably connected to the moving mold plate 14 along a direction perpendicular to the mold opening direction. The two first sliders 2 are symmetrically arranged on the moving mold plate 14 and are respectively used for forming the two side walls of the auxiliary instrument main body 10. The first slider 2 includes a first block 23 and a second block 24 that are connected to each other. An avoidance groove 22 is formed on the surface of the second block 24 connected to the first plate body 51, and the first block 23 blocks the notch of the avoidance groove 22. A mounting plate 5 is connected to the avoidance groove 22 along a direction perpendicular to the mold opening direction. The mounting plate 5 includes a first plate body 51 and a second plate body 52 that are connected to each other. The second plate body 52 is located on the side of the first plate body 51 close to the first block 23.

[0040] Refer to Figure 5 , Figure 7 and Figure 8, through grooves 25 communicating with the avoidance grooves 22 are formed on both side walls of the second block 24. The two ends of the two first plate bodies 51 respectively extend out of the corresponding slider one 2 through the four through grooves 25. Four fixing blocks 8 are detachably connected to the moving template 14, and the end portions of the two first plate bodies 51 extending out of the second block 24 are respectively inserted into the corresponding fixing blocks 8. The two first plate bodies 51 and the two second plate bodies 52 are immovable relative to the moving template 14.

[0041] Refer to Figure 5 , Figure 7 and Figure 8 , two sets of first control mechanisms 3 for respectively controlling the two sliders one 2 are arranged on the moving template 14. The first control mechanism 3 includes a pressing surface 31 formed at one end of the second block 24 away from the first block 23, and a plurality of first springs 32 installed on the second plate body 52. The plurality of first springs 32 all pass through the first plate body 51 and abut against the slider one 2. The elastic forces of the plurality of first springs 32 all act on the slider one 2, and the plurality of first springs 32 drive the slider one 2 to move away from the auxiliary instrument body 10 when the mold is opened; when the mold is closed, the fixed template 13 presses the two pressing surfaces 31 to drive the two second blocks 24 to move closer to each other and compress the plurality of first springs 32.

[0042] Refer to Figure 5 , Figures 7 - 12 , a plurality of forming areas 21 for forming the connecting buckles 101 are formed on the mutually approaching surfaces of the two first blocks 23, and a first forming block 4 for forming the first buckle groove 102 is arranged in the forming area 21. A plurality of angled lifter bases 6 are installed on the second plate body 52, angled lifter rods 7 are arranged on the angled lifter bases 6, the end portions of the angled lifter rods 7 penetrate through the second block 24 and extend into the forming area 21, and when the first block 23 moves away from the auxiliary instrument body 10, the angled lifter rods 7 are driven to move closer to the moving template 14 by pressing the angled lifter rods 7.

[0043] Refer to Figure 12 , the end portion of the angled lifter rod 7 includes a second forming block 91 for forming the second buckle groove 103 and a third forming block 92 for forming the third buckle groove 104. An installation cavity one 93 is formed on the second forming block 91, the third forming block 92 is connected in the installation cavity one 93 along the direction perpendicular to the mold opening direction, and a second control mechanism 95 is arranged on the second forming block 91. The second control mechanism 95 can control the third forming block 92 to slide into and out of the second forming block 91.

[0044] Refer to Figure 12, an installation cavity two 94 is formed on the forming block two 91. The second control mechanism 95 includes a rod body one 951, a second spring 952 arranged in the installation cavity two 94, a resisting block 953, a matching block 954 slidably connected in the installation cavity one 93 along the mold opening direction, a first inclined surface 955 and a second inclined surface 956 arranged on the matching block 954, a third inclined surface 957 and a fourth inclined surface 958 arranged on the forming block one 4. One end of the rod body one 951 extends into the installation cavity one 93 and is connected to 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 to the resisting block 953. The second spring 952 is sleeved on the rod body one 951 and abuts against the resisting block 953. The elastic force of the second spring 952 acts on the resisting block 953, and the second spring 952 always drives the resisting block 953 to move away from the installation cavity one 93. The cavity opening of the installation cavity two 94 is blocked by a copper plug after the second spring 952 and other components are installed.

[0045] Referring to Figures 12 - 14 , the first inclined surface 955 and the second inclined surface 956 are respectively arranged at the top and bottom of the matching block 954. The first inclined surface 955 is attached to the forming block three 92. When the forming block two 91 moves into the forming block three 92, it presses against the first inclined surface 955, driving the matching block 954 to approach 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 attached to the third inclined surface 957, and the second inclined surface 956 and the third inclined surface 957 have the same slope. The slope 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 presses against the forming block, driving the matching block 954 away from the bottom wall of the installation cavity one 93.

[0046] Referring to Figures 12 - 14 , the injection molding steps of the mold of the present application are as follows: First, operate the injection molding machine to control the mold to close, so that the moving template 14 moves closer to the moving template 14. During this process, the fixed template 13 will press against the two pressing surfaces 31, causing the two first blocks 23 and the two second blocks 24 to move closer to each other. When the two second blocks 24 move closer to each other, they will drive multiple inclined ejector rods 7 to move back to their original positions, causing multiple forming blocks two 91 and multiple forming blocks three 92 to move into multiple forming areas 21 respectively. At the same time, when the two second blocks 24 move closer to each other, they will also press against multiple first springs 32, causing the multiple first springs 32 to be compressed under force.

[0047] During the process of the third forming block 92 following the second forming block 91 into the forming area 21, the fourth inclined surface 958 of the first forming block 4 presses against the mating block 954 to drive the mating block 954 to slide away from the bottom wall of the first mounting cavity 93. When the mating block 954 slides away from the bottom wall of the first mounting cavity 93, it drives the third forming block 92 to move out of the first mounting cavity 93 through the first inclined surface 955, so that the third forming block 92 finally abuts against the first forming block 4, thus preparing for the formation of the third buckle groove 104. When the third forming block 92 moves out of the first mounting cavity 93, it drives the abutting block 953 to move close to the first mounting cavity 93 through the first rod 951, causing the second spring 952 to be compressed.

[0048] After the mold is fully 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 template 13 and the moving template 14 to complete 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 moving template 14 moves away from the fixed template 13.

[0049] As the fixed template 13 and the moving template 14 separate, the fixed template 13 gradually cancels the pressing on the two pressing surfaces 31. At this time, the multiple first springs 32 on the two mounting plates 5 will rebound to drive the two second blocks 24 to move away from each other. When the two second blocks 24 move away from each other, they will drive the two first blocks 23 to move away from the auxiliary instrument body 10.

[0050] During the process of the two first blocks 23 moving away from each other, the first forming block 4 will move out of the first buckle groove 102, and the multiple ejector pins 7 will move close to the moving template 14. At the same time, a cavity will be formed between the two first blocks 23 and the auxiliary instrument body 10, so that the ejector pins 7 and the second forming block 91 have enough movement space, so that the ejector pins 7 and the second forming block 91 will not collide with the first slider 2 when they move close to the moving template 14.

[0051] When the ejector pins 7 move close to the moving template 14, they will drive the second forming block 91 and the third forming block 92 to move close to the moving template 14 together, so that the second forming block 91 and the third forming block 92 move out of the connecting buckle 101.

[0052] During the movement of the first forming block 4 and the second forming block 91, the fitting range between the second inclined surface 956 and the third inclined surface 957 becomes smaller and smaller. Subsequently, with the movement of the second forming block 91 and the first forming block 4, the second inclined surface 956 and the third inclined surface 957 no longer fit together, and the fitting block 954 comes into contact with the fourth inclined surface 958. Subsequently, with the continuous movement of the first forming block 4 and the second forming block 91, the second spring 952 can gradually rebound and drive the abutting block 953 to move away from the first installation cavity 93. When the abutting block 953 moves away from the first installation cavity 93, it will drive the third forming block 92 to move into the first installation cavity 93 through the first rod body 951. When the third forming block 92 moves into the first installation cavity 93, it will press against the first inclined surface 955 to drive the fitting block 954 to move closer to the bottom wall of the first installation cavity 93, pressing the fitting block 954 against the fourth inclined surface 958. Before the first forming block 4 completely moves out of the first installation cavity 93, the third forming block 92 will completely move into the first installation cavity 93, and the fitting block 954 will also move to the position closest to the bottom wall of the first installation cavity 93 on its movement path.

[0053] If the third forming block 92 moves into the second forming block 91, it will prevent the third forming block 92 from colliding with the connecting buckle 101 when moving out of the second retaining groove 103. Thus, the connecting buckle 101 will not be deformed, reducing the risk of the connecting buckle 101 breaking when the second forming block 91 moves out of the second retaining groove 103. After the mold is completely opened, the auxiliary instrument main body 10 can be removed from the mold. After the auxiliary instrument main body 10 is removed from the mold, the injection molding machine controls the mold to close again to start the injection molding of the next auxiliary instrument column.

[0054] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope protected by this application.
