With the continuous development of the automobile industry and the continuous improvement of consumers' requirements for automobile performance, the automobile fuel tank, as a key component for storing fuel, its design, manufacturing and quality assurance are particularly important.

[0003] In recent years, the automobile manufacturing industry has begun to explore the use of one-piece molding technology to manufacture automobile fuel tanks. The one-piece molding technology uses a special mold processing technology to process the fuel tank as a whole, without the need for disassembly and assembly, thereby greatly simplifying the production process and improving production efficiency and material utilization. At the same time, the one-piece molding technology can also reduce the use of welding processes, reduce the generation of welding stress and residual stress, and improve the service life and safety of the fuel tank.

[0004] In the processing of the one-piece forming mold for automobile fuel tanks, when the mold is demolded after the processing is completed, a direct push-out method is often adopted, so that the mold is quickly separated from the processing equipment and falls downward into a collection frame. When the mold falls directly from a high place to the collection frame, a large impact force will be generated due to the effects of gravity and speed. The impact force may cause damage to the mold and affect the quality and durability of the mold. Therefore, an one-piece forming mold for automobile fuel tanks is proposed to solve the above problems. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 , Figure 3 , Figure 5The utility model provides an embodiment: an automobile fuel tank integrated molding die, comprising a body 1, the body 1 is an automobile fuel tank integrated molding die injection molding machine, a feed hopper 2 is arranged at the top of the body 1, a discharge port 3 for discharging the processed fuel tank is arranged on the front surface of the body 1, a buffer assembly is arranged on the inner wall of the discharge port 3, and the buffer assembly includes a fixed plate 38 for providing support, the fixed plate 38 is fixedly connected to the left inner wall of the discharge port 3, and a round rod 35 for providing support is rotatably connected to the top of the fixed plate 38, and the round rod 3 5 is fixedly connected to the right side thereof with a buffer plate 33 which can cooperate with a torsion spring 36 to slow down the speed at which the oil tank descends. The round rod 35 is elastically connected to the fixing plate 38 through the torsion spring 36. One end of the torsion spring 36 is fixedly connected to the outer wall of the round rod 35, and the other end of the torsion spring 36 is fixedly connected to the inner wall of the fixing plate 38. The processed oil tank falls downward and squeezes the buffer plate 33, and then squeezes the torsion spring 36. The buffer plate 33 is squeezed by the reverse force of the torsion spring 36, thereby slowing down the speed at which the oil tank falls downward and achieving a buffering effect.

[0034] Reference Figure 1 , Figure 2 , Figure 6 The inner wall of the feed hopper 2 is provided with a stirring assembly, which includes an auger 26 that can stir and break up the agglomerated materials. The top of the auger 26 is fixedly connected to a ring 25 that provides support and drives the auger 26 to rotate. The ring 25 is rotatably connected to the inner wall of the feed hopper 2.

[0035] Reference Figure 2 , Figure 4 , Figure 5 The bottom end of the fixed plate 38 is fixedly connected with a rubber pad 2 37 and two groups are provided. A slider 39 is slidably connected between the two groups of rubber pads 2 37. The rubber pad 2 37 is made of rubber material. The two groups of rubber pads 2 37 can increase the friction with the slider 39, thereby reducing the moving speed of the slider 39, and at the same time reducing the impact force of the oil tank falling downward and cooperating with the spring 34 to play a buffering effect. The right side of the slider 39 is fixedly connected with a support plate 31 for support. The top of the support plate 31 is fixedly connected with a rubber pad 1 32. The rubber pad 1 32 is made of rubber material, which can reduce the impact force of the oil tank falling downward. The top of the support plate 31 is set as an inclined plane, and the rubber pad 1 32 is set to be fixed in an inclined shape on the top of the support plate 31. By setting the top of the support plate 31 as an inclined plane and the rubber pad 1 32 as an inclined shape, the oil tank can slide downward along the top of the inclined rubber pad 1 32 into the collection frame after buffering downward.

[0036] Furthermore, the support plate 31 is elastically connected to the body 1 through a spring 34, one end of the spring 34 is fixedly connected to the bottom end of the support plate 31, and the other end of the spring 34 is fixedly connected to the inner wall of the bottom end of the discharge port 3. The rubber pad 1 32 and the support plate 31 are squeezed by the oil tank falling downward, and the spring 34 is squeezed at the same time. The reverse force of the squeezed spring 34, the rubber pad 2 37 and the slider 39 can reduce the impact force of the oil tank falling downward. At the same time, the buffer plate 33 and the torsion spring 36 can further improve the buffering effect, thereby preventing damage to the oil tank and improving the processing quality and service life. The buffer plate 33 is provided with two groups, and the two groups of buffer plates 33 are symmetrically arranged with the center line of the support plate 31 as the symmetry axis. The slider 39, the rubber pad 2 37, and the spring 34 are provided in multiple groups to improve the buffering effect.

[0037] Reference Figure 1 , Figure 2 , Figure 6 The inner wall of the ring 25 is fixedly connected with a gear rod 23 which meshes with the gear 24 and drives the ring 25 to rotate, and there are multiple groups of gear rods 23. The top of the body 1 is fixedly connected with a positioning plate 21 which provides support. The right side of the positioning plate 21 is fixedly installed with a motor which can drive the rotating rod 22 and the gear 24 to rotate. The motor is an existing structure and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The left side of the output shaft of the motor is fixedly connected with a rotating rod 22 which drives the gear 24 to rotate. The rotating rod 22 passes through and is rotatably connected to the left side of the positioning plate 21. The rotating rod 22 passes through and is rotatably connected to the inner wall of the feed hopper 2. The left side of the rotating rod 22 is fixedly connected with a gear 24 which meshes with the gear rod 23 and drives the gear rod 23 and the ring 25 to rotate by rotating. The gear rod 23 meshes with the gear 24, and the gear 24 can rotate and drive the gear rod 23 and the ring 25 to rotate.

[0038] Working principle: When in use, the fuel tank mold is demoulded and falls downward after being processed, and squeezes the buffer plate 33 after contacting the buffer plate 33, so that the buffer plate 33 rotates and drives the round rod 35 to rotate and squeeze the torsion spring 36. The reverse force of the torsion spring 36 is squeezed to reduce the impact force of the fuel tank falling downward, thereby providing a buffering effect. By reducing the impact force of the fuel tank falling downward, the fuel tank falls downward slowly, and squeezes the rubber pad 1 32 after falling to contact the rubber pad 1 32 and the support plate 31, so that the support plate 31 moves downward to squeeze the spring 34, and at the same time drives the slider 39 between the two The rubber pads 37 are arranged to slide between the two groups. By setting the rubber pads 37 to be made of rubber material, the friction with the slider 39 can be increased, thereby reducing the moving speed of the slider 39. At the same time, by setting the rubber pads 32 to be made of rubber material, the force of the oil tank falling can be buffered, thereby reducing the damage to the oil tank. Through the mutual cooperation between the slider 39, the rubber pads 37, the rubber pads 32, the support plate 31, the spring 34, the buffer plate 33, the round rod 35, and the torsion spring 36, a buffer effect can be provided, the impact force of the oil tank mold falling can be reduced, and the processing quality and service life of the oil tank can be further improved.

[0039] The motor drives the rotating rod 22 and the gear 24 to rotate, and the gear 24 engages with the toothed rod 23, so that the toothed rod 23 can rotate to drive the ring 25 and the auger 26 to rotate. The material in the feed hopper 2 can be stirred by the rotation of the auger 26, so as to prevent the material in the feed hopper 2 from agglomerating and causing blockage, thereby increasing the feeding speed and further improving the processing efficiency.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
