Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding equipment, and particularly relates to a turbo injection mold with a full - circumference slider. Background Art

[0002] At present, turbocharging technology is widely used in various vehicles, including passenger cars, commercial vehicles, and racing cars, etc. In the field of passenger cars, turbocharging technology is mainly used to increase the output power of small engines, enabling the vehicle to provide sufficient power while maintaining good fuel economy. In the field of commercial vehicles, turbocharging technology is more used to improve the torque and efficiency of diesel engines to meet the power and fuel efficiency requirements of heavy - duty transport vehicles. In the field of racing cars, turbocharging technology is used to increase the power output of the engine to achieve higher speeds and performance.

[0003] Turbo blades have the advantages of relatively light overall mass, not being prone to rust, and having relatively low noise during operation. Therefore, they are widely used in the automotive production process. The design of turbo blades will pay more attention to environmental adaptability to meet the performance requirements under different working conditions, including corrosion resistance, fatigue resistance, etc. Since the turbine rotates at a high speed during operation, if problems such as excessive deformation occur during its injection molding production, it will affect the normal operation of the crankcase.

[0004] Therefore, the above - mentioned problems have become technical problems that urgently need to be solved. Content of the Utility Model

[0005] Purpose of the utility model: In order to overcome the above deficiencies, the utility model provides a turbo injection mold with a full - circumference slider. An injection cavity is formed by combining a fixed template and a moving template. The slider assembly on the fixed template includes multiple slider bodies that are spliced in a full - circumference manner. The turbine forming part on the slider body and the metal insert form an injection mold cavity for the turbine in the injection cavity, solving the technological problem that cannot be achieved due to the small and dense spacing of turbine blades, and achieving the effect of an integrated design of the turbine structure.

[0006] Technical solution: In order to achieve the above purpose, the utility model provides a turbo injection mold with a full - circumference slider, including: a hot runner plate, a fixed template, a moving template, and a moving mold fixing seat. The moving template is arranged at the bottom of the hot runner plate, and the moving template is arranged on the moving mold fixing seat. A slider driving assembly is arranged on the fixed template, a slider assembly and a metal insert are arranged on the moving template. The metal insert is movably arranged at the center of the moving template. The slider assembly includes several slider bodies and guide blocks. The slider bodies are slidably connected to the guide blocks. The guide blocks are arranged radially on the moving template with the metal insert as the center. The slider driving assembly can drive the slider bodies to move on the guide blocks.

[0007] Preferably, cavities are provided on the opposite surfaces of the fixed template and the movable template. The slider driving assembly is arranged in the cavity of the fixed template, and the metal insert and the slider assembly are arranged in the cavity of the movable template.

[0008] The slider driving assembly includes a fixed mold plate embedded in the cavity of the fixed template. A slider driving rod is provided on the bottom surface of the fixed mold plate. The slider driving rod is wedge-shaped, and several locking grooves are also provided on the bottom surface of the fixed mold plate.

[0009] The slider body includes a turbine forming part, a slider sealant inclined surface, and a slider interlocking block. The slider body is L-shaped. The turbine forming part is arranged at one end of the slider body. A wedge opening for cooperating with the slider driving rod is provided at the other end of the slider body. The slider sealant inclined surfaces are arranged on both sides near one end of the turbine forming part. The slider interlocking block is arranged on the upper part of the slider body, and the slider interlocking block can cooperate with the locking grooves.

[0010] During mold closing, the fixed template and the movable template move closer to each other. The slider driving rod in the driving assembly inserts into the wedge opening on the slider body. Then, as the two continue to move closer, the slider driving rod causes all the slider bodies to slide along the guiding blocks. After the slider bodies move in place, the turbine forming part cooperates with the metal insert to form an injection mold cavity for the turbine. At the same time, the slider sealant inclined surfaces on the slider bodies cooperate in pairs to seal with the inclined surfaces, and the slider interlocking blocks just fit into the locking grooves on the fixed mold plate.

[0011] Furthermore, a movable mold core is further included. A slot for accommodating the slider assembly is provided on the movable mold core. An insert base is arranged at the center of the movable mold core. The movable mold core and the fixed mold plate cooperate to form an injection mold cavity, and the injection mold cavity is communicated with the injection port.

[0012] Furthermore, a spring is arranged between the slider body and the guiding block, and the slider body can move to compress the spring. During mold closing, the slider driving rod drives the slider body to move and compress the spring. When the injection molding is completed, the elastic force of the spring can be used to separate the slider body from the product, which is more convenient for demolding.

[0013] Furthermore, the cross-section of the guiding part of the guiding block is in the shape of a water droplet. In this mold, the number of slider bodies is relatively large. If the normal slider bar guiding is adopted, the mold layout will increase, and at the same time, the slider extends relatively long, which is prone to the risk of fracture. The water droplet-shaped design of the guiding block greatly saves the space layout, and at the same time, the reliable movement and long service life are guaranteed. On the other hand, the water droplet-shaped design is derived from aerodynamics, and the wire cutting processing method is used for part processing, which has high precision and guarantees the movement resistance and stability of the slider.

[0014] Further, it also includes a fixed mold clamping plate, a moving mold foot, and an ejection assembly. The fixed mold clamping plate is disposed above the hot runner plate. The moving mold foot and the ejection assembly are disposed on the moving mold fixing base, and the ejection assembly is located between the moving mold feet. The moving mold plate is disposed on the moving mold feet. The design of the moving mold feet provides an installation space for the ejection assembly.

[0015] Further, the ejection assembly includes an ejector plate, ejector pins, and a reset device. The ejector plate is disposed on the moving mold fixing base. The ejector pins are disposed on the ejector plate, and the ejector pins extend below the injection mold cavity.

[0016] The reset device includes a pneumatic telescopic rod and a return spring. The pneumatic telescopic rod is disposed between the ejector plate and the moving mold plate, and the return spring is sleeved on the pneumatic telescopic rod. After injection molding is completed, when the fixed mold plate is separated from the moving mold plate, the pneumatic telescopic rod drives the ejector plate to move upward to drive the ejector pins to eject the injection molded product, and the return spring returns the ejector plate to its original position.

[0017] Furthermore, guide posts are provided on the fixed mold plate, and guide holes are provided on the moving mold plate. The guide posts are matched with the guide holes. The fixed mold plate and the moving mold plate use the cooperation of the guide posts and the guide holes to achieve accurate mold closing. Embedded part positioning pins are provided on the moving mold plate, and the embedded part positioning pins are matched with metal inserts. The metal inserts are accurately installed through the embedded part positioning pins.

[0018] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:

[0019] 1. The present utility model provides a turbine injection mold with a full - circumference slider. An injection cavity is formed by combining a fixed mold plate and a moving mold plate. The slider assembly on the fixed mold plate includes multiple slider bodies, and the slider bodies are spliced in a full - circumference manner. The turbine forming part on the slider body and the metal insert form an injection mold cavity for the turbine in the injection cavity, solving the process problem that the small and dense spacing of turbine blades makes it impossible to achieve, and realizing the overall design effect of the turbine structure.

[0020] 2. The turbine injection mold with a full - circumference slider provided by the present utility model realizes the overall design effect of the turbine structure. The integrated turbine structure design, compared with the early two - part structure, solves the problem of component assembly deviation. The integration has the advantages of high overall performance, no deviation, low noise during high - speed operation, etc. It optimizes the structure and quantity of components, ensures the consistency of parts during high - speed movement, and solves problems such as noise caused by misalignment.

Detailed implementation manners

[0030] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] Please refer to Figure 1-7, A turbo injection mold with a full - circumference slider, comprising: a hot runner plate 1, a fixed mold plate 2, a movable mold plate 3, and a movable mold fixing seat 4. The movable mold plate 3 is disposed at the bottom of the hot runner plate 1, and the movable mold plate 3 is disposed on the movable mold fixing seat 4. A slider driving assembly 21 is provided on the fixed mold plate 2, and a slider assembly 31 and a metal insert 32 are provided on the movable mold plate 3. The metal insert 32 is movably arranged at the center of the movable mold plate 3. The slider assembly 31 includes a plurality of slider bodies 311 and guide blocks 312. The slider bodies 311 are slidably connected to the guide blocks 312. The guide blocks 312 are radially arranged on the movable mold plate 3 with the metal insert as the center. The slider driving assembly 21 can drive the slider bodies 311 to move on the guide blocks 312.

[0032] Preferably, cavities are provided on the opposite surfaces of the fixed mold plate 2 and the movable mold plate 3. The slider driving assembly 21 is disposed in the cavity of the fixed mold plate 2, and the metal insert 32 and the slider assembly 31 are disposed in the cavity of the movable mold plate 3;

[0033] The slider driving assembly 21 includes a fixed mold plate 211 embedded in the cavity of the fixed mold plate 2. A slider driving rod 212 is provided on the bottom surface of the fixed mold plate 211. The slider driving rod 212 is wedge - shaped, and a plurality of locking grooves 213 are also provided on the bottom surface of the fixed mold plate 211;

[0034] The slider body 311 includes a turbine forming part 3111, a slider sealant inclined surface 3112, and a slider interlocking block 3113. The slider body 311 is L - shaped. The turbine forming part 3111 is disposed at one end of the slider body 311. A wedge - shaped opening for cooperating with the slider driving rod 212 is provided at the other end of the slider body 311. The slider sealant inclined surfaces 3112 are disposed on both sides near one end of the turbine forming part 3111. The slider interlocking block 3113 is disposed on the upper part of the slider body 311. The slider interlocking block 3113 can cooperate with the locking grooves 213.

[0035] As a further optimized solution, it further includes a movable mold core 5. A slot for accommodating the slider assembly 31 is provided on the movable mold core 5. An insert base 51 is provided at the center of the movable mold core 5. The movable mold core 5 and the fixed mold plate 211 cooperate to form an injection mold cavity, and the injection mold cavity is communicated with the injection port.

[0036] Specifically, a spring is provided between the slider body 311 and the guide block 312. The movement of the slider body 311 can compress the spring. After injection molding, the slider body 311 can be smoothly separated from the product under the action of the spring.

[0037] In addition, as Figure 6As shown, the cross-section of the guiding part of the guiding block 312 is in the shape of a water droplet. However, the cross-section of the guiding block 312 in this embodiment is not limited to the shape of a water droplet, and it can also be in the shape of a T or other shapes that can achieve the function of a slide rail. In this embodiment, the guiding block 312 with a water-droplet cross-section is preferably used because the number of slider bodies 311 in this mold is relatively large. If the normal slider bar guiding is adopted, the mold layout will increase, and at the same time, the slider extends relatively long, which is prone to the risk of fracture. The water-droplet design of the guiding block 312 greatly saves the space layout, and at the same time, the reliable movement life is guaranteed; on the other hand, the water-droplet design is derived from aerodynamics, and the wire-cut machining method for part processing has high precision, ensuring the movement resistance and stability of the slider.

[0038] As Figure 1 , Figure 2 shown, it further includes a fixed mold fixing plate 6, a moving mold foot 7 and an ejection assembly 8. The fixed mold fixing plate 6 is arranged on the upper part of the hot runner plate 1. The moving mold foot 7 and the ejection assembly 8 are arranged on the moving mold fixing seat 4, and the ejection assembly 8 is located between the moving mold feet 7. The moving template 3 is arranged on the moving mold feet 7.

[0039] The ejection assembly 8 includes an ejector plate 81, ejector pins 82 and a reset device. The ejector plate 81 is arranged on the moving mold fixing seat 4. The ejector pins 82 are arranged on the ejector plate 81, and the ejector pins 82 extend to the lower part of the injection mold cavity.

[0040] The reset device includes a pneumatic telescopic rod 83 and a reset spring 84. The pneumatic telescopic rod 83 is arranged between the ejector plate 81 and the moving template 3, and the reset spring 84 is sleeved on the pneumatic telescopic rod 83.

[0041] As Figure 4 , Figure 8 shown, guide posts 22 are arranged on the fixed template 2, guiding holes are arranged on the moving template 3, the guide posts 22 are matched with the guiding holes, and insert positioning pins 33 are arranged on the moving template 3. The insert positioning pins 33 are matched with the metal inserts 32.

[0042] When the turbine injection mold with a full-circumference slider provided by the present utility model is in use, this turbine product is an insert injection molding. In the open mold state, the manipulator grabs and installs the metal insert 32 into the insert positioning pins 33 on the moving template 3; then the mold is closed, the fixed template 2 and the moving template 3 approach each other, the slider driving rod 212 in the slider driving assembly 21 inserts into the slider body 311 and drives the slider body 311 to start moving along the guiding block 312. As the fixed mold template 211 and the moving mold core 5 are closed, at this time, the locking groove 213 just coincides with the slider interlocking block 3113. The slider sealant inclined surfaces 3112 on each slider body 311 contact each other in pairs to seal with the inclined surface, and the turbine forming part 3111 constitutes the cavity at the root of the turbine blade, and then injection molding can start.

[0043] After the injection molding is completed, the fixed template 2 is separated from the moving template 3. Under the action of the spring, the slider body 311 is separated from the turbine product. The pneumatic telescopic rod 83 drives the ejector plate 81 to move upward, driving the ejector pin 82 to eject the product.

[0044] The mold moves from the open state to the closed state for injection molding, and the product is taken out during the mold opening. The operations are repeated in sequence to complete the production.

[0045] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
