Description

Technical Field

[0001] The utility model relates to the field of injection molding machines, in particular to a backpack-type bevel injection structure. Background Art

[0002] In recent years, the injection molding industry has developed rapidly. In order to meet the diversified needs of the market, multi-component injection molding machines have become a highlight of the industry. The injection molding machine is a common plastic processing equipment. Its working principle is mainly to inject the molten plastic into the mold cavity through the injection molding device of the injection molding machine, and then open the mold to take out the final product after cooling and shaping.

[0003] Chinese invention patent publication number CN214773516U proposes a counter-injection molding machine, which includes a frame, a clamping device and two injection devices. The clamping device and the injection device are both mounted on the frame, and the main and auxiliary injection devices are horizontally arranged on both sides of the clamping device to inject molten materials into the mold in the clamping device. Both injection devices slide on the frame so that the distance between the injection device and the clamping device can be adjusted.

[0004] Since the two injection devices and the clamping device are both large in size and the three are independently arranged, the entire injection molding machine is large in size and occupies a large area, and there is still room for improvement. Utility Model Content

[0005] In order to reduce the floor space occupied by an injection molding machine, the utility model provides a backpack-type bevel injection structure.

[0006] The utility model provides a backpack-type angled injection structure, which adopts the following technical solutions:

[0007] A backpack-type angled injection structure comprises a tail plate and a movable template that moves relative to the tail plate during injection molding, and also comprises an angled injection mechanism and a supporting mechanism for supporting the angled injection mechanism, wherein the supporting mechanism is fixedly connected to the top of the movable template and slides on the top of the tail plate so that the movable template drives the angled injection mechanism to move horizontally, and the angled injection mechanism is arranged on the top of the supporting mechanism and is inclined downward in a direction close to the movable template so as to obliquely inject the molten material from the movable template into the mold.

[0008] By adopting the above technical scheme, compared with the existing structure of the opposite-shot injection molding machine in which the main and auxiliary angled injection mechanisms are horizontally arranged on the front and rear sides of the clamping device, the support mechanism and the angled injection mechanism of the above structure are both located above the tail plate, and the angled injection mechanism is tilted on the support mechanism, so that the material can be tilted and injected into the mold between the clamping devices, so that the overall length and volume of the injection molding machine are greatly reduced, and the occupied area is reduced.

[0009] In addition, the supporting mechanisms in the above technical solution are respectively supported on the tail plate and the moving template, and the angled injection mechanism is fixedly arranged on the supporting mechanism, and the supporting mechanism slides on the tail plate. Since the distance between the tail plate and the moving template is short, the rigid structural strength of the supporting mechanism is better. When the moving template drives the supporting mechanism and the angled injection mechanism to move, the supporting mechanism is not easy to deform. The angled injection mechanism is installed on the supporting mechanism, which is more stable, so that the nozzle of the angled injection mechanism can always be aligned with the injection port of the mold, and it is not easy to deviate.

[0010] Optionally, a sliding assembly is provided between the support mechanism and the tailgate, and the sliding assembly includes an entire moving linear rail fixed to the bottom of the support mechanism and a linear rail slider fixed to the top of the tailgate and cooperating with the entire moving linear rail.

[0011] By adopting the above technical solution, by setting the entire movable linear rail on the support mechanism, the support mechanism can move synchronously with the movable template, and compared with the structural form in which the entire movable linear rail is set on the tail plate, the angled injection mechanism of the above structural form has a longer movable distance; and the support mechanism and the angled injection mechanism can reduce friction and slide more smoothly by sliding on the top of the tail plate using a sliding assembly.

[0012] Optionally, a fixed structure is arranged between the support mechanism and the movable template, and the fixed structure includes a connecting piece welded to the support mechanism and detachably connected to the top of the movable template, and a supporting rib connecting the support mechanism and the connecting piece to improve the rigidity strength.

[0013] By adopting the above technical solution, compared with the method of directly welding the support mechanism to the moving template, the support mechanism can be disassembled from the moving template by the fixed structure connection method, which is convenient for equipment maintenance. In addition, by providing support ribs, the connection strength between the support mechanism and the connecting member can be improved, so that when the moving template drives the support mechanism to move, the connecting member is not easy to fall off from the support mechanism.

[0014] Optionally, the fixing structure further includes a fixing plate fixedly mounted on the side wall of the movable template and an abutment member disposed on the fixing plate and connected to the connecting member for limiting horizontal relative movement between the connecting member and the movable template.

[0015] By adopting the above technical solution, when the injection molding machine is closing the mold, there is a tendency for the connecting part and the movable template to slip relative to each other. At this time, the bolts fixing the connecting part to the movable template are subjected to large shear stress and are easy to break. By providing a fixing plate and abutment parts, the connecting part is fixed to the movable template in both the vertical direction and the horizontal direction, thereby making the connection strength between the connecting part and the movable template higher.

[0016] Optionally, the length of the support mechanism is not greater than the distance from the tail of the tail plate to the end of the movable plate away from the tail plate when the mold is closed, and the length of the entire moving linear rail is not less than the moving distance of the movable plate.

[0017] By adopting the above technical scheme, the length of the support mechanism is reasonably set according to the distance relationship between the tail plate and the movable template, so that the support mechanism can realize the supporting function and moving function of the angled injection mechanism, and the overall length and volume of the support mechanism are small, thereby realizing the miniaturization of the product; and, since the distance between the tail plate and the movable template is short, the rigid structural strength of the support mechanism is better.

[0018] Optionally, the support mechanism includes a support base and a backpack support assembly disposed on the support base for mounting the angled injection mechanism;

[0019] A rotating connection structure for adjusting the rotation angle of the angled injection mechanism is arranged between the backpack support assembly and the support base, and a rotating fine-tuning assembly for adjusting the horizontal position of the nozzle of the angled injection mechanism and a height adjustment structure for adjusting the height position of the nozzle of the angled injection mechanism are also arranged between the two.

[0020] By adopting the above technical solution, when the injection nozzle of the angled injection mechanism needs to be replaced, the nozzle of the angled injection mechanism can be rotated to the side of the injection molding machine by rotating the backpack support component, so that the operator can easily replace the injection nozzle, which is convenient for equipment maintenance. In addition, the horizontal position of the nozzle of the angled injection mechanism is adjusted by rotating the fine-tuning component, and the height position of the nozzle of the angled injection mechanism is adjusted by the height adjustment structure to ensure that the nozzle can be aligned with the position of the injection port of the mold as required.

[0021] Optionally, the rotatable connection structure includes an adjustment plate, the bottom of the adjustment plate is fixedly connected to the support base, and the top of the adjustment plate is rotatably connected to the backpack support assembly.

[0022] By adopting the above technical scheme, the structural form of the rotating connection structure is specifically disclosed, and the backpack support assembly and the support base are connected by an adjustment plate. The adjustment plate is fixed on the support base so that the injection mechanism can slide synchronously with the support base, and the backpack support assembly can rotate on the support base. The structure is relatively simple, and when maintenance is required, the overall disassembly and assembly is relatively easy.

[0023] Optionally, the backpack support assembly has an inclined guide surface for the angled injection mechanism to slide obliquely, and the inclined guide surface is inclined downward toward the direction close to the movable template; a guide rail is arranged on the inclined guide surface, and a guide block cooperating with the guide rail is arranged at the bottom of the angled injection mechanism.

[0024] By adopting the above-mentioned technical solution, by setting guide rails and guide blocks, and the plane on the backpack support assembly for installing the angled injection mechanism has a certain inclination angle, the friction force on the angled injection mechanism is smaller, and the angled injection mechanism can slide more easily on the backpack support assembly, thereby adjusting the position of the angled injection mechanism.

[0025] Optionally, a power assembly for driving the angled injection mechanism to slide on the inclined guide surface is provided on the backpack support assembly, and the power assembly is fixedly connected to the bottom of the angled injection mechanism.

[0026] By adopting the above technical solution and providing a power assembly, the power assembly can drive the angle injection mechanism to move, which is more convenient.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] 1. A backpack-type angled injection structure, wherein a support base is arranged above the tail plate and the movable plate, and one end of the support base slides on the tail plate, and the other end is fixed to the movable plate. Since the distance between the tail plate and the movable plate is short, the rigidity of the support base is good, and the support base is not easily deformed due to the weight of the injection device;

[0029] 2. The backpack support assembly is rotatably arranged on the support base. When the injection nozzle of the angled injection mechanism needs to be replaced, the nozzle of the angled injection mechanism can be rotated to the side of the injection molding machine by rotating the backpack support assembly. At this time, the operator can easily replace the injection nozzle, which is convenient for equipment maintenance;

[0030] 3. By setting up a rotary fine-tuning component and a height adjustment structure, the nozzle of the angled injection mechanism can be adjusted in the horizontal direction and the height direction to ensure that the nozzle can be aligned with the position of the mold nozzle opening as required.

[0038] The following is combined with Figure 1-6 The utility model is described in further detail.

[0039] The utility model embodiment discloses a backpack-type bevel injection structure.

[0040] Reference Figure 1 A backpack angled injection structure includes a tail plate 1, a movable plate 2, a support mechanism 3 and an angled injection mechanism 4. The tail plate 1 and the movable plate 2 are both basic components of the injection molding machine. When opening and closing the mold, the movable plate 2 can move horizontally relative to the tail plate 1. The angled injection mechanism 4 is used to inject the molten material into the mold. The support mechanism 3 is arranged above the tail plate 1 and the movable plate 2 for the installation of the angled injection mechanism 4. One end of the support mechanism 3 is slidably mounted on the tail plate 1 through a sliding assembly 5, and the other end is fixed to the movable plate 2 through a fixed structure 6. When the injection molding machine performs the mold opening and closing action, the movable plate 2 can drive the support mechanism 3 and the angled injection mechanism 4 to move synchronously.

[0041] Reference Figure 1 and Figure 2 The support mechanism 3 includes a support base 31 and a backpack support assembly 32 mounted thereon. The support base 31 is a square metal frame formed by welding a plurality of square steel pipes.

[0042] Combination Figures 1 to 3The backpack support assembly 32 includes a bottom plate 321, an inclined plate 322 and a positioning plate 323. The bottom plate 321 is a square steel plate. There are two inclined plates 322, which are symmetrically arranged on both sides of the bottom plate 321. The inclined plate 322 has an inclined guide surface 3221, and the inclined guide surface 3221 is inclined downward in the direction close to the dynamic template 2. The positioning plate 323 is a square steel plate, which is arranged between the two inclined plates 322 for connecting the two inclined plates 322. The bottom plate 321, the inclined plate 322 and the positioning plate 323 are fixed by welding, and the structural strength is relatively high.

[0043] A sliding structure is provided between the inclined guide surface 3221 and the angled injection mechanism 4, and the sliding structure includes a guide block 41 and a guide rail 3222. The guide block 41 is provided at the bottom of the angled injection mechanism 4, and the guide rail 3222 is provided on the inclined plate 322 on the inclined guide surface 3221 for the guide block 41 to slide, so that the angled injection mechanism 4 is slidably installed on the inclined guide surface 3221 of the inclined plate 322. In order to prevent the angled injection mechanism 4 from sliding off the guide rail 3222, a limiting block 3223 is provided at the bottom of the guide rail 3222, and when the angled injection mechanism 4 slides on the inclined guide surface 3221, the angled injection mechanism 4 can abut against the limiting block 3223.

[0044] A rotating connection structure is provided between the backpack support assembly 32 and the support base 31, and the rotating connection structure includes an adjustment plate 311 and a rotating shaft 3211. The adjustment plate 311 is welded and fixed to the top of the support base 31, and the adjustment plate 311 is a square steel plate, and its width is adapted to the width of the support base 31. The rotating shaft 3211 is provided on the bottom plate 321, and the rotating shaft 3211 is plugged into the adjustment plate 311, and a pressure bearing for reducing friction is sleeved on the rotating shaft 3211, so that the backpack support assembly 32 can be horizontally rotated on the support base 31.

[0045] The backpack support assembly 32 is also provided with a height adjustment structure 324, a rotation fine adjustment assembly 325 and a power assembly 326. The height adjustment structure 324 is used to fine-tune the height of the backpack support assembly 32 to change the height position of the nozzle of the angled injection mechanism 4, the rotation fine adjustment assembly 325 is used to fine-tune the rotation angle of the backpack support assembly 32 on the support base 31 to change the horizontal position of the nozzle of the angled injection mechanism 4, and the power assembly 326 is used to drive the angled injection mechanism 4 to tilt and slide on the backpack support assembly 32.

[0046] Reference Figure 2 and Figure 3The height adjustment structure 324 includes an adjustment bolt 3241, which is threadedly connected to the bottom plate 321 and rotated on the adjustment plate 311. By rotating the adjustment bolt 3241, the bottom plate 321 can be vertically moved on the adjustment bolt 3241. In this embodiment, the number of the adjustment bolts 3241 is four, which are symmetrically arranged on both sides of the bottom plate 321.

[0047] Reference Figure 2 and Figure 4 The rotation fine-tuning assembly 325 includes a fixing seat 3251 , a driving bolt 3252 and a pushing block 3253 .

[0048] Reference Figure 3 and Figure 4 The fixing seat 3251 is fixed to the adjustment plate 311 by screws, and the fixing seat 3251 can slide slightly in the height direction along the screws. The driving bolt 3252 is horizontally passed through the fixing seat 3251, and the fixing seat 3251 has a through hole, and the diameter of the through hole is slightly larger than the diameter of the driving bolt 3252, so that the driving bolt 3252 can be tilted in the through hole. The push block 3253 is threadedly connected to the end of the driving bolt 3252 and fixedly installed on the side wall of the bottom plate 321 by screws. By rotating the driving bolt 3252, the push block 3253 can move on the driving bolt 3252, so that the backpack support assembly 32 can rotate slightly with the rotating shaft 3211 as the rotation center.

[0049] Combination Figures 1 to 4 When the horizontal fine adjustment of the nozzle of the angled injection mechanism 4 is performed by rotating the fine adjustment component 325, the adjusting bolt 3241 of the height adjustment structure 324 is first removed so that the backpack support component 32 can be rotated. When the height fine adjustment of the nozzle of the angled injection mechanism 4 is performed by the height adjustment structure 324, the rotating fine adjustment component 325 does not need to be removed.

[0050] When the nozzle of the angled injection mechanism 4 needs to be replaced, the operator needs to first remove the height adjustment structure 324 and the rotation fine adjustment assembly 325, and then rotate the backpack support assembly 32 so that the nozzle of the angled injection mechanism 4 can be rotated to the side facing the injection molding machine. When the nozzle of the angled injection mechanism 4 is replaced, the height adjustment structure 324 and the rotation fine adjustment assembly 325 are reinstalled.

[0051] Reference Figure 3 and Figure 5The power assembly 326 includes a full-shift motor 3261, a full-shift lead screw 3262, and a full-shift connector 3263. The full-shift motor 3261 is fixedly disposed on the positioning plate 323. The full-shift lead screw 3262 is rotatably disposed on the positioning plate 323, and the full-shift lead screw 3262 is parallel to the plane where the inclined guide surface 3221 is located. The full-shift connector 3263 is threadedly connected to the full-shift lead screw 3262 and is fixed to the bottom of the bevel injection mechanism 4 by screws.

[0052] The whole-shift motor 3261 drives the whole-shift lead screw 3262 to rotate, and the whole-shift connecting member 3263 can be displaced along the length direction on the whole-shift lead screw 3262, so that the angled injection mechanism 4 can slide on the inclined guide surface 3221.

[0053] Reference Figure 1 and Figure 2 The sliding assembly 5 includes a whole-moving linear rail 51 and a linear rail slider 52. The whole-moving linear rail 51 is fixed to the bottom of the support base 31 by welding, and the whole-moving linear rail 51 is arranged along the length direction of the support base 31. The linear rail slider 52 is fixedly installed on the top of the tail plate 1 by bolts. A sliding groove 53 is provided on the top of the linear rail slider 52 for the whole-moving linear rail 51 to slide into, so that the linear rail slider 52 can slide on the whole-moving linear rail 51.

[0054] Reference Figure 1 and Figure 6 The fixed structure 6 includes a connecting member 61, a supporting rib 63, a fixing plate 64 and an abutting member 65. The connecting member 61 includes a connecting block and a connecting plate. The connecting block 611 is a square steel pipe and is fixed to one end of the supporting base 31 close to the movable template 2 by welding. The connecting plate 612 is fixed to the bottom of the connecting plate 612 by welding, and the connecting plate 612 is fixed to the top of the movable template 2 by multiple sets of bolts, so that one end of the supporting base 31 is fixedly connected to the movable template 2. The supporting rib 63 is a metal steel plate, which is arranged between the connecting plate 612 and the connecting block 611 and between the connecting block 611 and the bottom of the supporting base 31, and is used to strengthen the structural strength of the fixed structure 6.

[0055] The fixing plate 64 is a metal steel plate, fixed to the side wall of the movable plate 2 by bolts, and a part of the fixing plate 64 extends out of the top of the movable plate 2. The abutment member 65 is a bolt structure, which is penetrated through the fixing plate 64 and threadedly connected to the side of the connecting plate 612, thereby further strengthening the structural strength of the fixing structure 6. When the movable plate 2 drives the supporting base 31 to slide, displacement between the connecting plate 612 and the movable plate 2 is not easy to occur.

[0056] Reference Figure 1 and Figure 2In order to control the size of the injection molding machine, thereby realizing the miniaturization of the equipment and improving the rigidity of the support base 31, in this embodiment, the length of the support base 31 is not greater than the distance from the tail of the tail plate 1 to the end of the movable plate 2 away from the tail plate 1 when the mold is closed. When the injection molding machine is in the mold closing state, the distance between the tail plate 1 and the movable plate 2 is the farthest. At this time, the support base 31 is located above the tail plate 1 and the movable plate 2, and the two ends of the support base 31 do not extend out of the tail plate 1 and the movable plate 2. The length of the whole moving linear rail 51 is not less than the moving distance of the movable plate 2 when the mold is opened and closed, so that the linear rail slider 52 is not easy to escape from the whole moving linear rail 51.

[0057] Since both ends of the support base 31 are supported, the angled injection mechanism 4 can be arranged at any position on the top of the support base 31 , and has good stability.

[0058] Combination Figures 1 to 6 The implementation principle of a backpack angled injection structure of the embodiment of the utility model is as follows: by setting the support base 31 above the tail plate 1 and the moving plate 2, and one end of the support base 31 slides on the tail plate 1, and the other end is fixed to the moving plate 2, so that the overall footprint of the injection molding machine is small. In addition, since the distance between the tail plate 1 and the moving plate 2 is short, the rigidity of the support base 31 is good, and when the moving plate 2 drives the support mechanism 3 and the angled injection mechanism 4 to move synchronously, the support base 31 is not easy to deform.

[0059] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
