Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to an integrated mold for combining an automotive turbocharger and exhaust pipe. Background Technology

[0002] With the continuous development of the automotive industry, turbocharging technology has been widely used because it can effectively improve engine power performance. As a key component of the engine exhaust system, the matching accuracy between the exhaust pipe and the turbocharger directly affects the overall efficiency of the engine. In order to reduce assembly errors, optimize space layout and improve the overall vehicle power performance, the integrated design of automotive turbochargers and exhaust pipes has become an important trend in the industry.

[0003] In the existing technology, for the molding mold of the integrated part of automobile turbocharger and exhaust pipe, due to the complex structure of the part, the requirements for the precision and stability of the mold are very strict. In terms of buffering during mold closing, some molds will be equipped with elastic components such as springs to alleviate a certain impact force during the mold closing process and make the mold closing action relatively smooth.

[0004] In the mold closing process, existing technologies rely on simple buffer structures in traditional molds, often using a single spring or rubber pad for impact cushioning. This results in the inability to effectively disperse the impact force during mold closing, leading to accelerated wear of mold components such as templates and guide pillars. This not only significantly shortens the mold's lifespan but also increases production costs due to frequent replacements. Furthermore, long-term use can cause dimensional deviations in the mold due to cumulative deformation, directly affecting the molding accuracy of parts and resulting in a decrease in product qualification rate. To address these issues, an integrated mold combining an automotive turbocharger and exhaust pipe is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated mold for automobile turbochargers and exhaust pipes, which aims to improve the problem of insufficient impact force dispersion caused by the simple buffer structure and reliance on a single spring or rubber pad in the traditional integrated mold for automobile turbochargers and exhaust pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated mold for an automotive turbocharger and exhaust pipe, comprising a bottom mold, a top mold at the top of the bottom mold, a connecting frame hinged to the bottom of the top mold, a slider hinged to the bottom end of the connecting frame, a buffer groove on the outer wall of the bottom mold, a sliding rod fixedly connected to the inner wall of the buffer groove, a fixing spring fixedly connected to the inner wall of the buffer groove, an airbag fixedly connected to the side wall of the slider, a telescopic spring fixedly connected to the inner wall of the airbag, an air inlet hole on the side wall of the airbag, a heat dissipation pipe fixedly connected to the inner wall of the bottom mold, a liquid injection pipe fixedly connected to the inner wall of the heat dissipation pipe, and a circulating water pump fixedly connected to the end of the liquid injection pipe.

[0010] The airbag is fixedly connected to the outer wall of the slider on the side away from the fixed spring, and the air inlet is opened on the outer wall of the airbag on the side away from the slider.

[0011] As a further description of the above technical solution:

[0012] The heat dissipation pipe penetrates the bottom mold, and the slider is slidably connected to the inner wall of the buffer groove.

[0013] As a further description of the above technical solution:

[0014] The airbag is located inside the buffer groove and positioned on the side away from the bottom mold.

[0030] 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.

[0031] Reference Figure 1 , Figure 3 , Figure 4This utility model provides an embodiment of an integrated mold for an automotive turbocharger and exhaust pipe, comprising a bottom mold 1, a top mold 2 on the top of the bottom mold 1, which cooperates with the bottom mold 1 to form a molding cavity, precisely fitting the shape of the integrated turbocharger and exhaust pipe part, ensuring the molding accuracy of the part, a connecting frame 3 hinged to the bottom of the top mold 2, realizing the movable connection between the top mold 2 and the slider 5, which can convert the vertical movement of the top mold 2 into the horizontal movement of the slider 5, and transmit the motion force more smoothly, the bottom end of the connecting frame 3 is hinged to the slider 5, which can transmit the movement of the top mold 2 to the buffer structure, and the outer wall of the bottom mold 1 is provided with a buffer groove 4 to provide sliding space for the slider 5, the size of which is the same as that of the slider 5. Block 5 matches and limits the movement range of slider 5, preventing slider 5 from deviating from the track. Slider 5 is slidably connected to the inner wall of buffer groove 4, ensuring that slider 5 moves along the set trajectory. A slide rod 6 is fixedly connected to the inner wall of buffer groove 4, guiding the sliding of slider 5 and ensuring that slider 5 always moves in a straight line, preventing slider 5 from tilting during sliding. A fixed spring 7 is fixedly connected to the inner wall of buffer groove 4, which can achieve buffering through elastic deformation, storing elastic potential energy when slider 5 is extruded, and mitigating the impact force during mold closing. The fixed spring 7 is sleeved on the outer wall of slide rod 6 to prevent the fixed spring 7 from shifting laterally, ensuring that the fixed spring 7 can only extend and retract along the axial direction of slide rod 6, improving... The lifespan of the spring is determined by fixing the end of the spring 7 away from the buffer groove 4 to the side wall of the slider 5. This allows the movement of the slider 5 to directly act on the fixed spring 7, enabling the spring to quickly sense the displacement changes of the slider 5 and generate buffering force in a timely manner. An airbag 8 is fixedly connected to the side wall of the slider 5. The airbag enhances the buffering effect through gas compression. The compressibility of the gas allows it to absorb more impact energy, forming a gentler buffer in conjunction with the spring. The airbag 8 is located inside the buffer groove 4 and positioned on the side away from the bottom mold 1, making reasonable use of the space inside the buffer groove 4 and avoiding direct contact with the bottom mold 1 to prevent interference. It also makes the buffering direction more reasonable. The airbag 8 is fixedly connected to the slider 5 away from the fixed spring. On one side of the outer wall of the spring 7, a bidirectional buffer structure is formed with the fixed spring 7. The inner wall of the airbag 8 is fixedly connected to the telescopic spring 9, which assists the airbag 8 in resetting and enhances the buffering capacity. When the airbag 8 is compressed, it is subjected to force together. When decompressed, it pushes the airbag 8 to quickly return to its original shape, thereby improving the response speed of the airbag 8. An air inlet 10 is provided on the side wall of the airbag 8 to facilitate the intake of air when the airbag 8 resets, replenishing the gas volume in the airbag 8 and ensuring that the airbag 8 can function normally during the next buffering. The air inlet 10 is located on the outer wall of the airbag 8 on the side away from the slider 5, so as to avoid the slider 5 blocking the air inlet 10 when it moves, ensuring smooth air intake and preventing the airbag 8 from failing to reset properly due to insufficient air intake.

[0032] Reference Figures 1-3The inner wall of the bottom mold 1 is fixedly connected to a heat dissipation pipe 11 for circulating coolant to achieve heat dissipation. The pipes are distributed close to the heat-generating areas of the bottom mold 1 to expand the heat dissipation area and improve the heat dissipation efficiency. The heat dissipation pipe 11 runs through the bottom mold 1 to ensure that the coolant can enter and exit the bottom mold 1 to complete the circulation, forming a continuous heat dissipation path and avoiding the coolant from stagnating in the pipe and causing heat dissipation failure. The inner wall of the heat dissipation pipe 11 is fixedly connected to a liquid injection pipe 13 to provide a channel for the coolant to enter the heat dissipation pipe 11. Its pipe diameter is reasonably designed to ensure sufficient coolant flow to meet the heat dissipation requirements. The end of the liquid injection pipe 13 is fixedly connected to a circulating water pump 12 to provide power for the coolant circulation. The power of the water pump can be adjusted to control the coolant flow rate and adapt to the heat dissipation requirements under different working conditions.

[0033] Reference Figures 1-3 A flexible hose 16 is fixedly connected to the inner wall of the airbag 8 to guide air from the airbag 8 into the connecting pipe 14. The hose 16 is made of soft and aging-resistant material and can flexibly deform with the expansion and contraction of the airbag 8. The hose 16 is telescopic to adapt to the expansion and contraction of the airbag 8, avoiding damage to the hose 16 due to the movement of the airbag 8 and ensuring the continuity of the airflow channel. A one-way valve 15 is fixedly connected to the top of the hose 16 to prevent liquid or gas in the heat dissipation pipe 11 from flowing back into the airbag 8, ensuring that air can only flow from the airbag 8 to the heat dissipation pipe 11, protecting the airbag 8 from coolant corrosion. A connecting pipe 14 is fixedly connected to the end of the one-way valve 15 to deliver air from the one-way valve 15 to the heat dissipation pipe 11. The pipe is made of sturdy material and can withstand the pressure and temperature inside the heat dissipation pipe 11. The end of the connecting pipe 14 away from the one-way valve 15 passes through the heat dissipation pipe 11 and is fixedly connected to the inner wall of the heat dissipation pipe 11 to ensure that air can smoothly enter the heat dissipation pipe 11. The interface is well sealed to prevent coolant leakage and air loss.

[0034] Working principle: The top mold 2 moves downward, and the connecting frame 3 at its bottom hinges accordingly, causing the slider 5 to slide within the buffer groove 4 on the outer wall of the bottom mold 1. When the slider 5 moves along the slide rod 6, it compresses the fixed spring 7 on one side. The fixed spring 7 generates a reverse elastic force through deformation, initially buffering the impact force during mold closing. At the same time, the airbag 8 on the other side of the slider 5 is compressed, and the telescopic spring 9 on the inner wall of the airbag 8 contracts synchronously, further absorbing the impact energy. The double buffer structure effectively reduces the mechanical stress at the moment of mold closing and protects the stability of the mold structure. When the mold opens, the elastic force of the fixed spring 7 and the telescopic spring 9 is released, pushing the slider 5 to return to its original position. The airbag 8 draws in air through the air inlet 10 on the side wall, preparing for the next buffering. Meanwhile, the heat dissipation pipe 11 on the inner wall of the bottom mold 1 is connected to the circulating water pump 12 through the liquid injection pipe 13. The circulating water pump 12 drives the coolant to flow continuously within the heat dissipation pipe 11, promptly removing the heat generated during mold operation and preventing the product molding quality from being affected by excessive temperature. In addition, the retractable hose 16 fixed to the inner wall of the airbag 8 is connected to the connecting pipe 14 through the one-way valve 15. The connecting pipe 14 is connected to the heat dissipation pipe 11. When the airbag 8 is compressed, the internal air enters the heat dissipation pipe 11 through the hose 16, the one-way valve 15 and the connecting pipe 14, which can help enhance the flow disturbance of the coolant, improve the heat dissipation efficiency, and achieve the synergistic effect of buffering and heat dissipation.
