Description

Technical Field

[0001] This utility model relates to the field of mold tooling technology, specifically a multifunctional injection mold tooling. Background Technology

[0002] Injection molds are specialized tools used for plastic molding. They work in conjunction with injection molding machines to inject molten plastic raw materials into the mold cavity. After cooling and solidification, a plastic product with a shape that is completely consistent with the cavity is obtained. It is the core equipment of the injection molding process. Almost all thermoplastic and some thermosetting plastic products (such as appliance housings, automotive parts, medical device accessories, etc.) rely on injection molds for production.

[0003] In existing technology, when operating an injection mold, only a single mold can be used for injection molding. When it is necessary to switch to different shaped processing molds to produce diversified products, the operator must first stop the operation and then carry out the mold disassembly and replacement process. During this period, the injection molding machine and other equipment are completely idle, resulting in a serious waste of production resources. Especially in multi-variety production scenarios, frequent downtime for mold changing will significantly compress the effective production time and reduce the overall processing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional injection mold tooling to solve the problem mentioned in the background art that existing injection molds can only be used for a single mold during operation, and require machine shutdown and disassembly / replacement when switching to different molds to produce various products, resulting in idle injection molding machines and other equipment, wasting resources, compressing effective production time, and reducing overall processing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional injection mold tooling, including a base, a height adjustment component disposed at the bottom of the base, a drive component disposed on the base, a support rod rotatably connected to the base, a placement frame fixedly connected to the top of the support rod, a clamping component disposed on the placement frame, and a mold assembly detachably mounted on the placement frame. The drive component drives the placement frame to rotate intermittently, and the clamping component is used to clamp and fix the mold assembly.

[0006] Based on the preferred embodiment of this technical solution, four sets of clamping components and mold components are provided, and the four sets of clamping components and mold components are symmetrically distributed on the placement rack.

[0007] According to the preferred embodiment of this technical solution, the drive component includes a motor fixedly connected to the bottom of the base, a rotating disk rotatably connected to the base, a bracket fixedly connected to the rotating disk at one end, a light rod fixedly connected to the other end of the bracket, and an intermittent rotating frame fixedly connected to the support rod. The rotating disk is fixedly connected to the output end of the motor, and the light rod is set on the intermittent rotating frame.

[0008] Based on the preferred embodiment of this technical solution, a through slot is provided at the corresponding position of the light rod on the intermittent rotating frame, and four sets of through slots are provided, with the four sets of through slots symmetrically distributed on the intermittent rotating frame.

[0009] Based on the preferred embodiment of this technical solution, the mold assembly includes a lower mold mounted on a placement frame, an upper mold detachably mounted on top of the lower mold, an injection port fixedly connected to the top of the upper mold, a first mounting bolt mounted on the upper mold, and the first mounting bolt being connected to the interior of the lower mold.

[0010] According to the preferred embodiment of this technical solution, the clamping assembly includes a long rod rotatably connected to the placement frame, a rotating handle fixedly connected to one end of the long rod, a first bevel gear fixedly connected to the other end of the long rod, a bidirectional threaded rod rotatably connected inside the placement frame, a second bevel gear fixedly connected to the bidirectional threaded rod at the position corresponding to the first bevel gear, a clamping frame slidably connected to the placement frame, and an anti-slip pad fixedly connected to the inner side of the clamping frame. The second bevel gear meshes with the first bevel gear, and the clamping frame is threadedly connected to the outside of the bidirectional threaded rod.

[0011] In a preferred embodiment of this technical solution, the placement rack has a sliding groove at a corresponding position on the clamping rack, and the clamping rack is slidably connected to the sliding groove of the placement rack.

[0012] According to the preferred embodiment of this technical solution, the height adjustment component includes a support frame disposed at the bottom of the base, an adjusting inner rod fixedly connected to the bottom of the base, a first through hole opened on the adjusting inner rod, a second through hole opened on the support frame, a second mounting bolt disposed inside the first through hole and the second through hole, and a mounting nut threadedly connected to the second mounting bolt, wherein the adjusting inner rod is slidably connected to the support frame.

[0013] Based on the preferred embodiment of this technical solution, four sets of first through holes are provided, and the four sets of first through holes are distributed sequentially from top to bottom on the adjusting inner rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. With a four-station setup, injection molding can be performed at one station while operators can easily replace mold components at the other three stations without stopping the overall operation. This effectively avoids the downtime issues caused by mold changes in traditional single-mold operations. By driving the placement rack to rotate intermittently through the drive component, the mold component to be injected can be precisely rotated to the processing station, realizing the synchronization of injection molding and mold change.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This utility model provides an embodiment of a multifunctional injection mold fixture, including a base 1, a height adjustment component disposed at the bottom of the base 1, a drive component disposed on the base 1, a support rod 25 rotatably connected to the base 1, a placement frame 27 fixedly connected to the top of the support rod 25, a clamping component disposed on the placement frame 27, and a mold assembly detachably mounted on the placement frame 27. The drive component drives the placement frame 27 to rotate intermittently, and the clamping component is used to clamp and fix the mold assembly. With a four-station setup, injection molding can be performed at one station while the operator can conveniently replace the mold assemblies at the other three stations without stopping the overall operation, effectively avoiding the downtime problem caused by mold replacement in traditional single mold operation. By driving the placement frame 27 to rotate intermittently, the mold assembly to be injected can be accurately rotated to the processing station, realizing the synchronous operation of injection molding and mold replacement, greatly reducing equipment idle time, simplifying the mold replacement process, and ultimately significantly improving overall processing efficiency and reducing the waste of production resources.

[0020] Please see Figure 1-2 A further solution based on this embodiment is as follows: four sets of clamping components and mold components are provided. The four sets of clamping components and mold components are symmetrically distributed on the placement frame 27. By setting four sets of symmetrically distributed clamping components and mold components, four different molds can be accommodated at the same time for operation preparation. When one mold component is in the injection molding operation station, the operator can change and adjust the mold in the other three stations, realizing the parallel processing of injection molding operation and mold change, greatly reducing the downtime caused by mold change, and significantly improving the continuous operation capability of the equipment.

[0021] Please see Figure 2 A further solution based on this embodiment is as follows: The driving component includes a motor 21 fixedly connected to the bottom of the base 1, a rotating disk 22 rotatably connected to the base 1, a bracket 23 fixedly connected to the rotating disk 22 at one end, a light rod 24 fixedly connected to the other end of the bracket 23, and an intermittent rotating frame 26 fixedly connected to the support rod 25. The rotating disk 22 is fixedly connected to the output end of the motor 21, and the light rod 24 is set on the intermittent rotating frame 26. The motor 21 drives the rotating disk 22 to rotate, which drives the bracket 23 and the light rod 24 to move synchronously. Under the action of the intermittent rotating frame 26, the light rod 24 causes the support rod 25 to rotate intermittently, thereby realizing the orderly intermittent rotation of the placement frame 27. This ensures that each mold component can accurately stop at the injection station, which not only ensures the stability of the injection operation, but also provides sufficient time for mold replacement at other stations. The structure is simple and the operation is reliable.

[0022] Please see Figure 2A further solution based on this embodiment is as follows: a through slot is provided on the intermittent rotating frame 26 at the corresponding position of the guide rod 24, and four sets of through slots are provided. The four sets of through slots are symmetrically distributed on the intermittent rotating frame 26. By providing four sets of symmetrically distributed through slots on the intermittent rotating frame 26, the guide rod 24 can drive the intermittent rotating frame 26 to rotate in steps by embedding different through slots. Each rotation corresponds to the switching of a work station, so that the rotation angle of the placement frame 27 is precisely controllable, ensuring that each mold component can be accurately aligned with the working position of the injection molding machine, avoiding injection errors caused by inaccurate positioning, and improving the accuracy of the operation.

[0023] Please see Figure 4 A further solution based on this embodiment is as follows: the mold assembly includes a lower mold 41 disposed on the placement frame 27, an upper mold 42 detachably mounted on the top of the lower mold 41, an injection port 43 fixedly connected to the top of the upper mold 42, and a first mounting bolt 44 disposed on the upper mold 42. The first mounting bolt 44 is bolted to the inside of the lower mold 41, and the upper mold 42 and the lower mold 41 are detachably connected by the first mounting bolt 44, which facilitates the quick disassembly of the internally formed model according to production needs. The setting of the injection port 43 ensures that the molten plastic can be accurately injected into the mold cavity, while the bolt connection method ensures the sealing and stability of the mold during operation.

[0024] Please see Figure 3 A further embodiment of this solution includes: a clamping assembly comprising a long rod 31 rotatably connected to a placement frame 27, a rotating handle 32 fixedly connected to one end of the long rod 31, a first bevel gear 33 fixedly connected to the other end of the long rod 31, a bidirectional threaded rod 34 rotatably connected inside the placement frame 27, a second bevel gear 35 fixedly connected to the bidirectional threaded rod 34 at a position corresponding to the first bevel gear 33, a clamping frame 36 slidably connected to the placement frame 27, and an anti-slip pad 37 fixedly connected to the inner side of the clamping frame 36; the second bevel gear 35 and the first bevel gear... The clamping frame 36 is threadedly connected to the outside of the bidirectional threaded rod 34. By rotating the handle 32, the long rod 31 and the first bevel gear 33 are rotated. The bidirectional threaded rod 34 is rotated by the meshing transmission of the first bevel gear 33 and the second bevel gear 35, which in turn drives the clamping frames 36 on both sides to move closer or further away, thereby realizing the clamping and releasing of the mold assembly. The anti-slip pad 37 can increase the friction between the clamping frame 36 and the mold assembly, preventing the mold from sliding during rotation or injection molding. It is suitable for mold assemblies of different sizes and improves the efficiency of mold changing.

[0025] Please see Figure 3A further solution based on this embodiment is as follows: the placement frame 27 has a sliding groove at the corresponding position of the clamping frame 36, and the clamping frame 36 is slidably connected to the sliding groove of the placement frame 27. By opening the sliding groove on the placement frame 27, the clamping frame 36 can slide stably along the sliding groove, ensuring that the clamping frame 36 can maintain linear movement under the drive of the bidirectional threaded rod 34, avoiding the situation of deviation or jamming during clamping. The sliding groove plays a guiding and limiting role for the clamping frame 36, further improving the stability and clamping accuracy of the clamping assembly, and ensuring the positional accuracy of the mold assembly during operation.

[0026] Please see Figure 1 , Figure 5 A further solution based on this embodiment is as follows: The height adjustment component includes a support frame 51 disposed at the bottom of the base 1, an adjusting inner rod 52 fixedly connected to the bottom of the base 1, a first through hole 53 opened on the adjusting inner rod 52, a second through hole 54 opened on the support frame 51, a second mounting bolt 55 disposed inside the first through hole 53 and the second through hole 54, and a mounting nut 56 threadedly connected to the second mounting bolt 55. The adjusting inner rod 52 is slidably connected to the support frame 51. By adjusting the sliding of the adjusting inner rod 52 within the support frame 51, the height of the base 1 and the entire fixture can be changed. When adjusted to a suitable height, the second mounting bolt 55 passes through the corresponding first through hole 53 and second through hole 54 and is fixed by the mounting nut 56 to achieve precise height adjustment. This allows the fixture to adapt to injection molding machines or operating scenarios of different heights, improving the versatility and flexibility of the equipment.

[0027] Please see Figure 5 A further solution based on this embodiment is as follows: four sets of first through holes 53 are provided, and the four sets of first through holes 53 are distributed sequentially from top to bottom on the adjusting inner rod 52. By providing four sets of first through holes 53 distributed sequentially from top to bottom on the adjusting inner rod 52, multiple gear selections are provided for height adjustment. The operator can select different positions of the first through holes 53 to cooperate with the second through holes 54 on the support frame 51 for fixing according to actual needs, so as to realize multi-level adjustment of the tooling height, meet the diverse height requirements in different working environments, and make the adjustment process more convenient and efficient.

[0028] Working principle: First, the overall height is adjusted using the height adjustment component: According to the height requirements of the injection molding machine, the operator slides the inner rod 52 to adjust its position within the support frame 51, aligning the appropriate first through hole 53 with the second through hole 54 of the support frame 51, and then uses the second mounting bolt 55 and mounting nut 56 to fix it, completing the precise adaptation of the tooling height. Next, the mold assembly is installed on the four workstations of the placement frame 27: The lower mold 41 is placed on the placement frame 27, and the upper mold 42 is fixed to the lower mold 41 using the first mounting bolt 44, forming a complete mold assembly. Then, the rotating handle 32 is turned, driving the long rod 31 and the first bevel gear 33 to rotate. Through the meshing transmission with the second bevel gear 35, the bidirectional threaded rod 34 rotates, thereby driving the two clamping frames 36 to move synchronously along the slide groove of the placement frame 27. Recently, the lower mold 41 is firmly clamped by the inner anti-slip pad 37. After the operation starts, the drive component drives the placement frame 27 to rotate intermittently: the motor 21 drives the rotating disk 22 to rotate, so that the bracket 23 drives the guide rod 24 to move synchronously. The guide rod 24 is embedded in the through slot of the intermittent rotating frame 26 and drives it to rotate step by step. The support rod 25 drives the placement frame 27 to rotate. Each rotation accurately delivers a set of mold components to the injection station. The other three stations can simultaneously carry out mold replacement or preparation work. When a set of mold components arrives at the injection station, the injection molding machine injects molten plastic into the cavity through the injection port 43 of the upper mold 42. After the injection is completed, the drive component continues to drive the placement frame 27 to rotate, and transfers the next set of mold components to be operated to the injection station, realizing the synchronous operation of injection molding and mold replacement, which greatly improves the overall processing efficiency.
