A straight groove 142 for connecting the two oblique grooves 141 is also opened in the middle of the side edge of the main body 14. In order to meet the molding requirements, the oblique groove 141 has an inclination angle of 60 degrees, which makes it difficult to demold the product when the oblique groove 141 and the core plate 21 are formed during product injection molding. Therefore, how to smoothly demold the product after the injection molding is completed becomes a problem that needs to be solved. Utility Model Content

[0003] The present application provides an injection mold slider mechanism for converting an upper body frame of an instrument panel by sliding up and down at a large angle, which can effectively solve the problem of difficult product demoulding caused by an oblique groove.

[0004] The slide block mechanism of the injection mold for converting the upper body frame of the instrument panel provided in the present application adopts the following technical solution:

[0005] The upper body frame of the instrument panel slides up and down at a large angle conversion injection mold slider mechanism, including an upper mold and a lower mold, the lower mold includes a core plate, a lower bottom plate, a first top plate and a second top plate connected to each other, an ejection assembly arranged on the second top plate, and a driving part for driving the first top plate to move, the core plate is provided with a receiving groove, the receiving groove is provided with a forming block for forming an inclined groove, the forming block is slidably connected in the receiving groove along the inclined direction of the inclined groove, the bottom surface of the forming block is provided with a receiving hole along the inclined direction of the inclined groove, the receiving hole is provided with a spring for driving the forming block to slide, and the core plate is also provided with an auxiliary sliding mechanism for assisting the sliding of the forming block to avoid the forming block from getting stuck.

[0006] By adopting the above technical solution, when the mold is opened, the compressed spring rebounds to drive the molding block to slide, so that the molding block is away from the main body frame of the instrument panel, so that the main body frame of the instrument panel can be demoulded smoothly, and an auxiliary sliding mechanism is provided to assist the sliding of the molding block to avoid the phenomenon of the molding block getting stuck during the sliding process due to excessive sliding angle.

[0007] Preferably, the auxiliary sliding mechanism includes a pulling block arranged on the forming block and a driving component arranged in the accommodating groove for driving the pulling block to move.

[0008] By adopting the above technical solution, the pulling block is driven to move by the driving assembly to assist in demoulding of the forming block.

[0009] Preferably, the driving assembly includes a sliding seat slidably connected in the accommodating groove along a direction perpendicular to the mold opening direction, an inclined guide column arranged on the upper mold, an inclined hole for inserting the inclined guide column is provided on the end of the sliding seat away from the forming block, and a first sliding groove is provided on the end close to the sliding seat along the inclination direction perpendicular to the inclined groove, and a sliding block is provided at the end of the pulling block away from the forming block, and the sliding block is slidably connected in the first sliding groove along the length direction of the first sliding groove.

[0010] By adopting the above technical solution, when the mold is opened, the lower mold will move away from the upper mold, and the slide will move away from the inclined guide column. Under the guidance of the inclined guide column, the slide will slide away from the core plate. The slide will drive the pull block during the sliding process. When the pull block is pulled, due to the limitation of the forming block, the slider will slide along the first slide groove, thereby driving the pull block to slide obliquely upward relative to the slide. The oblique upward sliding process of the pull block will pull the forming block to slide, thereby assisting the demoulding of the forming block.

[0011] Preferably, two guide seats are detachably connected at both ends of the accommodating groove, and second slide grooves are opened on opposite surfaces of the two guide seats along the inclined direction of the inclined groove. The two ends of the forming block are slidably connected in the two second slide grooves.

[0012] By adopting the above technical solution, the friction force of the forming block during sliding can be reduced by setting the slide groove of the guide seat and polishing it to cooperate with the forming block. At the same time, after the mold has been injected for tens of thousands of times, the guide seat can be removed and the second slide groove can be polished again, thereby ensuring the smoothness of the movement of the sliding block and improving the service life of the mold.

[0013] Preferably, the driving part is a cylinder, an L-shaped groove is provided on the first top plate in the vertical direction, and a clamping component for clamping into the L-shaped groove so that the cylinder controls the movement of the first top plate is provided on the output shaft of the cylinder.

[0014] By adopting the above technical solution, when the output rod of the oil cylinder is extended or retracted, it will drive the first top plate and the second top plate to move, thereby driving the ejection assembly to move to eject the product.

[0015] Preferably, the connecting assembly includes an I-shaped block for clamping in the L-shaped groove and a fixing plate fixedly connected to the output shaft of the cylinder. A clamping groove for clamping with the output shaft of the cylinder is provided on the top of the I-shaped block.

[0016] By adopting the above technical solution, the assembly of the mold is facilitated.

[0017] Preferably, a stopper is provided on the first top plate to prevent the I-shaped block from escaping from the L-shaped groove.

[0018] By adopting the above technical solution, after the connecting block is inserted into the L-shaped groove, the stopper is used to block the L-shaped groove, thereby preventing the I-shaped block from detaching from the L-shaped groove when the mold is used, thereby ensuring normal production of the mold.

[0019] The technical effects of this utility model are mainly reflected in the following aspects:

[0020] 1. The utility model drives the forming block to slide by the spring rebound, so that the forming block is away from the instrument panel upper body frame, so that the instrument panel upper body frame can be demoulded smoothly.

[0021] 2. The utility model converts the mold opening force of the mold into the sliding force of the forming block through the inclined guide column, the slide seat and the pull block;

[0022] 3. The utility model inserts the connecting block into the L-shaped groove, so that when the output rod of the oil cylinder is extended or retracted, it will drive the first top plate and the second top plate to move, thereby driving the ejection assembly to move and eject the product.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings to make the technical solution of the present application easier to understand and grasp.

[0034] The embodiment of the present application discloses a slider mechanism for an injection mold that can convert a main body frame of an instrument panel into an upper and lower sliding shape at a large angle.

[0035] Reference Figure 3-Figure 5 The mechanism of the sliding block 6 of the injection mold for converting the upper body 14 of the instrument panel of this embodiment to slide up and down at a large angle includes an upper mold 1 and a lower mold 2. The upper mold 1 includes an upper bottom plate 11, a hot runner plate 12 fixed on the upper bottom plate 11 for installing the hot runner, and a cavity plate 13 fixed on the hot runner plate 12. The lower mold 2 includes a lower bottom plate 24, a core plate 21 connected to the lower bottom plate 24 through a plurality of mold feet and a plurality of connecting columns (the mold feet are not shown in the figure), a first top plate 22 and a second top plate 23 connected to each other, an ejection assembly arranged on the second top plate 23, and a driving part 10 for the movement of the first top plate 22. The ejection assembly is a plurality of ejector rods and ejector blocks fixedly connected above the ejector rods. When the mold is closed, the core plate 21 and the cavity plate 13 are combined to form a molding cavity for product molding. The first top plate 22 and the second top plate 23 are installed between the core plate 21 and the lower bottom plate 24. The second top plate 23 is fixedly connected to the first top plate 22. Multiple guide columns are also installed between the core plate 21 and the lower bottom plate 24. The second top plate 23 and the first top plate 22 are slidably connected to the multiple guide columns along the opening direction of the mold.

[0036] Reference Figure 3-Figure 7The driving part 10 is four oil cylinders 101, and the four oil cylinders 101 are fixedly connected to the two sides of the core plate 21 in pairs. Two L-shaped grooves 221 are respectively provided on the two sides of the first top plate 22. The output shafts of the four oil cylinders 101 are provided with a connecting assembly 8 for clamping into the L-shaped groove 221 so that the oil cylinder 101 controls the movement of the first top plate 22. The connecting assembly 8 includes an I-shaped block 81 for clamping into the L-shaped groove 221, a fixing plate 82 fixedly connected to the output shaft of the oil cylinder 101, and a clamping groove 811 is provided on the top of the I-shaped block 81 for clamping with the output shaft of the oil cylinder 101. Four stoppers 9 are also detachably connected to the first top plate 22 by bolts to prevent the I-shaped block 81 from being separated from the L-shaped groove 221. When assembling the mold, first, the four I-shaped blocks 81 are inserted into the L-shaped grooves 221, and the four stoppers 9 are installed on the first stopper 9 by bolts to block the four L-shaped grooves 221 openings, and then the four oil cylinders 101 are installed on the core plate 21, and then the core plate 21 is lifted by a crane and installed on multiple connecting columns, and the output shafts of the four oil cylinders 101 are clamped into the four slots 811, and then the fixing plate 82 is fixed to the top of the top block by bolts to play a limiting role, and the assembly difficulty of the mold is simplified by the combined installation.

[0037] Reference Figure 3 , Figure 5 , Figure 8 , Fig. 9 Two receiving grooves 211 are provided on the core plate 21, and the two receiving grooves 211 penetrate the core plate 21 in a direction perpendicular to the mold opening direction of the mold. Two guide seats 7 are detachably connected to each other at both ends of each receiving groove 211 by bolts, and a forming block 3 for forming the inclined groove 141 is provided in each receiving groove 211. Second slide grooves 71 are provided on the opposite sides of the two guide seats 7 in the same receiving groove 211 along the inclined direction of the inclined groove 141. The two ends of each forming block 3 are respectively connected to the two sets of second slide grooves 71 in a sliding manner along the inclined direction of the inclined groove 141. The bottom surfaces of the two forming blocks 3 are provided with receiving holes 31 along the inclined direction of the inclined groove 141. The two receiving holes 31 are provided with springs 4 for driving the two forming blocks 3 to slide respectively. The springs 4 are in a compressed state when the mold is closed.

[0038] Reference Figure 3 , Figure 5 , Figure 8 , Fig. 9 The sliding angle of the slider 6 on the traditional mold is generally not more than 45 degrees, but because the inclined angle of the inclined groove 141 on the body 14 of the instrument panel is 60 degrees, the sliding angle of the molding block 3 in the second sliding groove 71 is relatively large, and it is easy to get stuck during the sliding process. Therefore, the core plate 21 is also provided with two auxiliary sliding mechanisms for assisting the two molding blocks 3 to slide and avoid the two molding blocks 3 from getting stuck.

[0039] Reference Figure 3 , Figure 5 , Figure 8 , Fig. 9 The auxiliary sliding mechanism 5 includes a driving assembly 52 fixedly connected to the side of the forming block 3 away from the core plate 21 and arranged in the receiving groove 211 for driving the pull block 51 to move. The driving assembly 52 includes a slide 521 slidingly connected to the receiving groove 211 along a direction perpendicular to the mold opening direction, and two fixedly connected to the bottom of the cavity plate 13. An inclined hole 5211 for inserting the inclined guide column 522 is provided on the end of the slide 521 away from the forming block 3, and two first slide grooves 5212 are provided on the end close to the slide 521 along the inclined direction perpendicular to the inclined groove 141. The first slide grooves 5212 are T-shaped grooves. Two sliders 6 are fixedly connected to the end of the pull block 51 away from the forming block 3. The two sliders 6 are respectively slidably connected in the first slide grooves 5212 along the length direction of the two first slide grooves 5212.

[0040] Reference Figure 3-Figure 9 When the mold is opened, the injection molding machine will move the lower mold 2 away from the upper mold 1. At this time, the slide 521 will move away from the inclined guide column 522. Under the guidance of the inclined guide column 522, the slide 521 will slide away from the core plate 21. The slide 521 will drive the pull block 51 during the sliding process. When the pull block 51 is pulled, due to the limitation of the forming block 3, the slider 6 will slide along the first slide groove 5212, thereby driving the pull block 51 to slide upward obliquely relative to the slide 521. The process of the pull block 51 sliding upward obliquely will pull the forming block 3 to slide along the second slide groove 71, thereby assisting the spring 4 to drive the forming block 3 away from the skeleton of the instrument panel upper body 14. At this time, the four oil cylinders 101 start to drive the first top plate 22 and the second top plate 23 to move toward the core plate 21, thereby driving the ejector pin and the ejector block to eject the skeleton of the instrument panel upper body 14 covered on the core plate 21, and complete the demoulding of the skeleton of the instrument panel upper body 14.

[0041] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
