Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to an opening and closing buffer mechanism for an integrated vehicle frame forming mold. Background Technology
[0002] One-piece frame molding die is an advanced manufacturing tool that can mold raw materials into a complete frame structure in one go, eliminating the need for segmented manufacturing and subsequent splicing, thereby significantly improving production efficiency, overall frame strength and precision.
[0003] Traditional mold opening and closing buffers typically use springs to absorb impact energy. However, spring buffers are prone to deformation or fatigue damage when subjected to large impact forces, and it is inconvenient to flexibly adjust the buffering effect according to usage requirements. Therefore, we propose an integrated frame forming mold opening and closing buffer mechanism. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an opening and closing buffer mechanism for an integrated vehicle frame forming mold.
[0005] This utility model is achieved using the following technical solution: an integrated vehicle frame forming mold opening and closing buffer mechanism, including a base, support seats fixedly connected to the four corners of the bottom of the base, a fixed seat fixedly connected to the top of the base, a fixed mold fixedly connected to the top of the fixed seat, guide rods fixedly connected to the four corners of the top of the fixed seat, a top plate fixedly connected to the top of the guide rods, a hydraulic rod fixedly connected to the top of the top plate, the output end of the hydraulic rod penetrating the top plate and fixedly connected to a mounting plate, a moving mold fixedly connected to the bottom of the mounting plate, a spring sleeved on the surface of the guide rods, two sets of symmetrically arranged buffer components provided at the bottom of the mounting plate, and a filter component provided at the bottom of the buffer components;
[0006] The buffer assembly includes a cylinder, a piston is slidably connected to the inner wall of the cylinder, a movable rod is fixedly connected to the top of the piston, an air outlet pipe is connected to the bottom of the cylinder, and a valve is fixedly installed on the inner wall of the air outlet pipe.
[0007] With the above technical solution, when the movable rod moves downward, the piston slides inside the cylinder, the gas inside the cylinder is compressed, and the gas is discharged through the vent pipe. During the exhaust process, the amount of gas passing through the vent pipe is limited, which realizes secondary buffering, reduces the impact force when the mold is closed, and improves the service life of the spring and the mold. The exhaust speed of the vent pipe can be adjusted by the valve, which makes it convenient to adjust the buffering effect according to the needs and improves practicality.
[0008] As a further improvement to the above solution, the bottom of the cylinder is fixedly connected to the top of the base, and the top of the movable rod extends to the outside of the cylinder and is fixedly connected to the bottom of the mounting plate.
[0009] With the above technical solution, since the movable rod is fixedly connected to the mounting plate, the movable rod will move during the movement of the mounting plate.
[0010] As a further improvement to the above solution, the bottom of the air outlet pipe penetrates through the base.
[0011] With the above technical solution, since the vent pipe passes through the base, it is convenient to discharge gas through the vent pipe.
[0012] As a further improvement to the above solution, the filter assembly includes a threaded cap, the bottom of which has a through hole, and a filter screen is disposed inside the threaded cap.
[0013] Through the above technical solution, the gas entering the cylinder body will be filtered by the filter screen to prevent dust or impurities from entering the cylinder body and affecting the piston movement, thus extending the service life of the buffer assembly. Since the threaded cover is connected to the outlet pipe by threads, it is convenient to disassemble and clean or replace the filter screen later.
[0014] As a further improvement to the above solution, the inner wall of the threaded cover is threadedly connected to the surface of the air outlet pipe, and the top of the filter screen contacts the bottom of the air outlet pipe.
[0015] With the above technical solution, when the threaded cap is threadedly connected to the air outlet pipe, the filter screen will contact the bottom of the air outlet pipe, which will squeeze and fix the filter screen.
[0016] As a further improvement to the above solution, the inner wall of the mounting plate is slidably connected to the surface of the guide rod, and the mounting plate is located above the spring.
[0017] The above technical solution guides the mounting plate with guide rods, preventing it from shifting during movement and ensuring accuracy during mold closing.
[0018] As a further improvement to the above solution, the bottom of the spring is fixedly connected to the top of the fixed base.
[0019] With the above technical solution, the mounting plate will come into contact with the spring when it moves downward, causing the spring to compress and achieving initial cushioning.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This invention features a buffer assembly. Specifically, when the mounting plate moves downward, it pushes the movable rod to move. At this time, the piston slides inside the cylinder, compressing the gas inside the cylinder. The gas is then discharged through the exhaust pipe. During the exhaust process, the volume of gas passing through the exhaust pipe is limited, thus achieving secondary buffering. This reduces the impact force during mold closing, improves the service life of the spring and the mold, and allows for adjustment of the exhaust speed of the exhaust pipe via a valve. This facilitates adjustment of the buffering effect according to requirements, enhancing practicality.
[0022] This invention incorporates a filter assembly, specifically filtering the gas entering the cylinder through a filter screen to prevent dust or impurities from entering the cylinder and affecting piston movement, thus extending the service life of the buffer assembly. Furthermore, the threaded cap's connection to the outlet pipe facilitates subsequent disassembly for cleaning or replacement of the filter screen. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0031] Example:
[0032] Please combine Figure 1-5This embodiment of an integrated vehicle frame forming mold opening and closing buffer mechanism includes a base 1, a support seat 2 fixedly connected to the four bottom corners of the base 1, a fixed seat 3 fixedly connected to the top of the base 1, a fixed mold 4 fixedly connected to the top of the fixed seat 3, a guide rod 5 fixedly connected to the four top corners of the fixed seat 3, a top plate 6 fixedly connected to the top of the guide rod 5, a hydraulic rod 7 fixedly connected to the top of the top plate 6, the output end of the hydraulic rod 7 passing through the top plate 6 and fixedly connected to a mounting plate 8, a moving mold 9 fixedly connected to the bottom of the mounting plate 8, a spring 10 sleeved on the surface of the guide rod 5, two sets of symmetrically arranged buffer components 11 provided at the bottom of the mounting plate 8, and a filter component 12 provided at the bottom of the buffer components 11.
[0033] The buffer assembly 11 includes a cylinder 1101, a piston 1102 slidably connected to the inner wall of the cylinder 1101, a movable rod 1103 fixedly connected to the top of the piston 1102, and an exhaust pipe 1104 connected to the bottom of the cylinder 1101. A valve 1105 is fixedly installed on the inner wall of the exhaust pipe 1104. The output end of the hydraulic rod 7 pushes the mounting plate 8 downward, causing the moving mold 9 to move closer to the fixed mold 4. When the mounting plate 8 moves downward, it contacts the spring 10, achieving initial buffering. At the same time, it pushes the movable rod 1103 downward. At this time, the piston 1102 slides inside the cylinder 1101, and the gas inside the cylinder 1101 is compressed. The gas is discharged through the exhaust pipe 1104. During the exhaust process, the volume of gas passing through the exhaust pipe 1104 is limited, achieving secondary buffering, reducing the impact force during mold closing, and improving the service life of the spring and the mold. The exhaust speed of the exhaust pipe 1104 can be adjusted by the valve 1105, which facilitates the adjustment of the buffering effect according to the needs and improves practicality.
[0034] The bottom of the cylinder body 1101 is fixedly connected to the top of the base 1, and the top of the movable rod 1103 extends to the outside of the cylinder body 1101 and is fixedly connected to the bottom of the mounting plate 8.
[0035] The bottom of the air outlet pipe 1104 passes through the base 1.
[0036] The filter assembly 12 includes a threaded cap 1201 with a through hole 1202 at the bottom. A filter screen 1203 is installed inside the threaded cap 1201. The gas entering the cylinder 1101 will be filtered by the filter screen 1203 to prevent dust or impurities from entering the cylinder 1101 and affecting the movement of the piston 1102, thus extending the service life of the buffer assembly 11.
[0037] The inner wall of the threaded cap 1201 is threadedly connected to the surface of the air outlet pipe 1104, and the top of the filter screen 1203 contacts the bottom of the air outlet pipe 1104. Since the threaded cap 1201 is threadedly connected to the air outlet pipe 1104, it is convenient to disassemble and clean or replace the filter screen 1203 later.
[0038] The inner wall of the mounting plate 8 is slidably connected to the surface of the guide rod 5, and the mounting plate 8 is located above the spring 10.
[0039] The bottom of the spring 10 is fixedly connected to the top of the fixed base 3.
[0040] The implementation principle of the mold opening and closing buffer mechanism of an integrated frame molding die in this application embodiment is as follows: During use, the output end of the hydraulic rod 7 pushes the mounting plate 8 downward, causing the moving mold 9 to move closer to the fixed mold 4. When the mounting plate 8 moves downward, it will contact the spring 10, achieving initial buffering. At the same time, it will push the movable rod 1103 downward. At this time, the piston 1102 slides inside the cylinder 1101, and the gas inside the cylinder 1101 is compressed. The gas is discharged through the vent pipe 1104. During the exhaust process, the amount of gas passing through the vent pipe 1104 is limited, achieving secondary buffering, reducing the impact force during mold closing, and improving the service life of the spring and the mold. The vent pipe 1104 can be adjusted by the valve 1105. The exhaust speed of 4 allows for easy adjustment of the buffering effect according to needs, improving practicality. When the hydraulic rod 7 moves the mounting plate 8 upward, the movable rod 1103 also moves upward, and the piston 1102 moves upward inside the cylinder 1101. The volume inside the cylinder 1101 increases, and external gas enters the cylinder 1101 through the exhaust pipe 1104. The gas entering the cylinder 1101 is filtered by the filter screen 1203 to prevent dust or impurities from entering the cylinder 1101 and affecting the movement of the piston 1102, thus extending the service life of the buffer assembly 11. Since the threaded cover 1201 is threadedly connected to the exhaust pipe 1104, it is convenient to disassemble and clean or replace the filter screen 1203 later.
[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
