Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a high-stress mould for processing vacuum cleaner accessories. Background Art

[0002] Vacuum cleaner accessories processing involves the use of precision molds and advanced manufacturing processes to achieve efficient, low-cost mass production. With the continuous growth of the market for household and commercial cleaning equipment, the demand for vacuum cleaners and their accessories is increasing, which has promoted the continuous improvement of production processes.

Through precision-designed molds, manufacturers can simplify the production process, reduce material waste, and reduce manufacturing costs while ensuring product consistency and quality.

[0004] During the processing of vacuum cleaner accessories, each time the mold is closed, the high-speed moving parts will suddenly stop, generating a strong impact force; and during the opening process, due to the lack of an effective buffering mechanism, violent collisions and vibrations will occur between the components of the mold; these unnecessary vibrations and impact forces will not only cause serious mechanical stress to the mold itself, accelerate its wear and aging process, and shorten its service life, but also have an adverse effect on the surrounding precision instruments and equipment; in addition, the internal structure of the mold that has been working in such a high-vibration environment for a long time may gradually crack or deform, further reducing the molding accuracy and product quality; it is not convenient to introduce appropriate damping measures in the mold design to improve production efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the high-stress mold for vacuum cleaner parts processing, the support component optimizes the interaction between the mold body and the die assembly to ensure high stability and accuracy during the stamping process; when the die assembly applies pressure to the mold body, the support component not only provides stable support to ensure the linear movement and smooth operation of the die assembly, avoiding precision loss and product defects caused by offset or vibration, but also greatly improves production efficiency and product quality; At the moment when the die assembly presses against the mold body, the built-in damping and shock-absorbing mechanism of the support assembly can respond quickly, effectively absorbing and dissipating the shaking caused by the pressure shock on the mold body, reducing the wear and fatigue damage of the mold, extending its service life, and greatly reducing the noise level in the working environment, improving the working conditions of the operator.

[0018] 2. In the high-stress mold for processing vacuum cleaner accessories, when the die assembly is pressed against the mold body and paused at the moment of fitting, the groove at the end of the mold body can be used to buffer and release pressure, thereby reducing the impact force on the mold body; specifically, at the moment after the die assembly stops, there is still forward pressure due to inertia; at this time, the special groove structure at the end of the mold body can effectively absorb and disperse this part of the inertial pressure, preventing it from directly acting on the mold surface, avoiding deformation or damage to the mold caused by sudden high-pressure impact; this design not only protects the structural integrity of the mold and extends its service life, but also ensures the accuracy and consistency of each stamping operation, reducing the scrap rate.

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-Figure 4 As shown, the purpose of this embodiment is to provide a high-stress mold for processing vacuum cleaner accessories, including a base 1, a vertical plate 11 is fixedly connected to the top of the base 1 near one end thereof, a support plate 12 is fixedly connected to the end of the top of the base 1 away from the vertical plate 11, and a mold body 13 is fixedly connected to the outer wall of one side of the vertical plate 11 near the support plate 12; A support assembly 14 is provided between the vertical plate 11 and the mold body 13. The support assembly 14 passes through the mold body 13 and is fixedly connected to the outer wall of the support plate 12. A plurality of support assemblies 14 are respectively fixedly connected between the vertical plate 11 and the support plate 12 near the four corners. A die assembly 15 is provided inside the support plate 12. The die assembly 15 is slidably connected between the outer walls of the plurality of support assemblies 14 and the top of the base 1. The support assembly 14 is used to limit the position of the mold body 13 and the die assembly 15. When the die assembly 15 processes the accessories inside the mold body 13, the die assembly 15 can relieve the impact force when it stops instantly. In addition, the support assembly 14 can provide stability for the moving direction of the die assembly 15 during the stamping process. The support assembly 14 can also damp and reduce the shaking of the mold body 13 at the moment when the die assembly 15 stops impacting. The improvements of this embodiment are as follows: first, the support assembly 14 can accurately limit the position of the mold body 13 and the die assembly 15, ensuring that the two can maintain an ideal position relationship in each operation, thereby improving the processing accuracy and reducing the scrap rate; second, when the die assembly 15 stops instantly during the process of processing the internal parts of the mold body 13 by the die assembly 15, its built-in pressure relief mechanism can respond quickly, effectively absorb and disperse the instantaneous impact force, prevent excessive pressure from directly acting on the mold, and protect the integrity of the mold structure; In addition, the support assembly 14 provides stability for the moving direction of the die assembly 15 during the entire stamping process, ensuring that the die assembly 15 runs smoothly along a straight path and avoids deviation or vibration, which is essential for maintaining high-precision, high-stress processing; finally, the support assembly 14 is also equipped with an efficient damping and shock absorption system, which can immediately cushion the shaking of the mold body 13 caused by pressure at the moment the impact of the die assembly 15 stops, thereby greatly reducing the wear and fatigue damage of the mold and extending its service life.

[0023] First, the specific structure of the support assembly 14 is disclosed. The support assembly 14 includes a guide member 140, which is fixedly connected between the vertical plate 11 and the support plate 12 near the four corners. The outer wall of the guide member 140 is provided with a damping member 141, which is fixedly connected to the inside of the mold body 13 near the four corners. The damping member 141 moves between the mold body 13 and the vertical plate 11; See also Figure 4 , Figure 7 and Figure 8 As shown, the guide member 140 is supported between the support plate 12 and the vertical plate 11 to support the mold body 13 located at the end of the vertical plate 11, and at the same time, the die assembly 15 is limitedly supported during the movement; when the die assembly 15 punches the mold body 13, the pressure exerted on the mold body 13, if it causes the mold body 13 to shake, causes the damping member 141 inside the mold body 13 to slide on the guide member 140, thereby reducing the shaking frequency of the mold body 13, improving the stability of the mold body 13, and reducing the mechanical stress on the mold itself caused by vibration and impact force during the processing.

[0024] The guide member 140 includes a liquid storage cylinder 1400, which is fixedly connected to the outer wall of the vertical plate 11 near the four corners, and a floating piston 1403 is provided inside the liquid storage cylinder 1400. A sealing plug 1402 is provided at one end of the liquid storage cylinder 1400; a guide rod 1401 is fixedly connected between the end of the sealing plug 1402 and the support plate 12, a die assembly 15 is provided between the outer walls of the four guide rods 1401, and a damping member 141 is provided between the outer wall of the liquid storage cylinder 1400 and the mold body 13; The damping member 141 includes a sleeve 1410, which is fixedly connected to the mold body 13 near the four corners, and is movably connected between the liquid storage cylinder 1400 and the outer wall of the guide rod 1401. A support rod 1411 is provided inside the sleeve 1410; the support rod 1411 is movably connected between the liquid storage cylinder 1400 and the inside of the guide rod 1401, and a working piston 1412 is fixedly connected to the end of the support rod 1411. The working piston 1412 is located inside the liquid storage cylinder 1400, and the working piston 1412 is located between the floating piston 1403 and the sealing plug 1402. See also Figure 4 , Figure 8 , Fig. 9 and Fig.10 As shown, the working cooperation between the guide member 140 and the damping member 141 is similar to the working principle of the damper. As known to those skilled in the art, the working principle of the damper is to absorb and dissipate vibration or impact energy by converting mechanical energy into heat energy, thereby reducing the movement amplitude and speed of the system. When an external force acts on the damper, the internal working plug moves in the hydraulic oil or other fluid medium, forcing the fluid to pass through a precisely designed throttle hole or valve to generate resistance. In this process, the resistance to fluid flow converts the input mechanical energy into heat energy, thereby consuming excess energy, thereby achieving the effect of shock absorption and stability. The sealing assembly ensures that the fluid does not leak and maintains the pressure balance of the system, while the floating plug and other structural components help regulate the internal pressure and volume changes to ensure that the damper can work smoothly and efficiently under various conditions. In this solution, when external impact force is applied, the force exerted on the mold body 13 will be synchronously transferred to the sleeve 1410, and the sleeve 1410 drives the support rod 1411 to move, so that the working piston 1412 compresses the hydraulic oil in the liquid storage cylinder 1400 under the guidance of the support rod 1411; by designing a throttle hole on the working piston 1412, the fluid in the liquid storage cylinder 1400 is transferred from the high-pressure area to the low-pressure area, and the mechanical energy is converted into heat energy through the fluid resistance generated in this process, thereby consuming the impact energy; and During the compression of the working piston 1412, the floating piston 1403 will automatically adjust the volume balance of the chambers on both sides according to the pressure changes inside the liquid storage cylinder 1400 to maintain the stability of the system; the sealing plug 1402 ensures the airtightness of the liquid storage cylinder 1400 to prevent fluid leakage; and during the movement of the sleeve 1410, the guide rod 1401 will provide stability for the movement of the sleeve 1410 and keep the guide rod 1401 moving smoothly; at the same time, the guide rod 1401 also supports the movement of the die assembly 15.

[0025] Next, the specific structure of the punch assembly 15 is disclosed. The punch assembly 15 includes a punch plate 150, which is slidably connected between the outer walls of the four guide rods 1401. The punch plate 150 is located between the die body 13 and the support plate 12. The outer wall of one end of the punch plate 150 is fixedly connected to a piston rod of a cylinder 151, and the cylinder 151 is fixedly connected to the inside of the support plate 12. A buffer 152 is provided inside the punch plate 150 near the outer wall of the other end. See also Figure 3 and Figure 5 As shown, the punch plate 150 is driven to move on the base 1 by the piston rod of the cylinder 151, so that the punch plate 150 is close to the inside of the mold body 13, and in the process of the movement of the punch plate 150, the moving direction of the punch plate 150 is limited by four guide rods 1401, so that the punch plate 150 always keeps moving in a straight line, and at the same time provides stable support for the movement of the punch plate 150; When the punch plate 150 moves to the end of the mold body 13, it will stop moving. At this time, the instantaneous impact force of the punch plate 150 will cause the mold body 13 to shake. Therefore, when the punch plate 150 moves to the inside of the mold body 13, it will drive the buffer 152 to move to the inside of the groove of the mold body 13, and the instantaneous pressure when the punch plate 150 touches the mold body 13 will be released through the buffer 152.

[0026] The buffer 152 includes a pad 1520, a groove is provided inside the punch plate 150, the pad 1520 is movably connected inside the groove of the punch plate 150, and a plurality of slide bars 1521 are fixedly connected to the outer wall of one end of the pad 1520; the slide bar 1521 is movably connected inside the punch plate 150, and a plurality of elastic members 1522 are fixedly connected between the groove of the punch plate 150 and the pad 1520, and the elastic members 1522 are wound around the outer wall of the slide bar 1521; a groove is provided at the end of the mold body 13, the pad 1520 is movably connected between the groove of the mold body 13 and the groove of the punch plate 150, and the pad 1520 is made of rubber; See also Figure 3 and Figure 6 As shown, when the punch plate 150 rushes toward the mold body 13, it will drive the pad 1520 to move preferentially into the groove of the mold body 13, and the pad 1520 will preferentially touch the mold body 13, and the punch plate 150 will continue to move toward the mold body 13, which will compress the elastic member 1522 between the pad 1520 and the punch plate 150, and at the same time drive the slide bar 1521 to move inside the punch plate 150, and support the movement of the pad 1520 through the slide bar 1521; when the elastic member 1522 is compressed, its rebound force will form a relative force with the impact force of the punch plate 150, and the instantaneous impact force of the punch plate 150 touching the mold body 13 will be released, thereby reducing the loss of the punch plate 150 hitting the mold body 13; Furthermore, by designing the pad 1520 to be made of rubber material, rubber is a widely used elastomeric material with good vibration absorption performance. It can effectively absorb and dissipate energy and reduce impact; it provides effective buffering and shock absorption for mold processing, reduces vibration and impact force, protects the mold body 13 and increases its service life.

[0027] In summary, the working principle of this scheme is as follows: In the precision mold processing system, the punch plate 150 is driven by the piston rod of the cylinder 151 to move accurately in a straight line on the base 1, ensuring that the punch plate 150 is smoothly approached to the inside of the mold body 13; in this process, the four guide rods 1401 accurately limit the moving direction of the punch plate 150, which not only maintains its straight line motion path, but also provides the necessary stable support, ensuring the consistency and accuracy of the operation; When the punch plate 150 approaches the end of the mold body 13 and stops, in order to avoid shaking and damage to the mold body 13 caused by the instantaneous impact force, a buffer mechanism consisting of a pad 1520, an elastic member 1522 and a slide bar 1521 is designed; the pad 1520 preferentially contacts the inside of the groove of the mold body 13, and as the punch plate 150 continues to move, it compresses the elastic member 1522, and at the same time the slide bar 1521 slides in the punch plate 150 to provide additional support; this structure allows the rebound force of the elastic member 1522 and the impact force of the punch plate 150 to form a relative force, effectively relieving pressure and reducing the loss caused by direct impact; the pad 1520 made of rubber material further enhances the vibration absorption performance, can efficiently absorb and dissipate energy, significantly reduce vibration and impact force, thereby protecting the mold body 13 and extending its service life; In addition, in order to cope with the possible shaking of the die body 13 during the stamping process, the guide member 140 is installed between the support plate 12 and the vertical plate 11, firmly supporting the die body 13 located at the end of the vertical plate 11; once the pressure applied by the punch plate 150 causes the die body 13 to shake, the force will be synchronously transferred to the sleeve 1410, and then the working piston 1412 will be driven by the support rod 1411 to compress the hydraulic oil in the liquid storage cylinder 1400; the throttle hole design on the working piston 1412 allows the fluid to flow from the high-pressure area to the low-pressure area. The fluid resistance in this process converts mechanical energy into heat energy and consumes excess impact energy; at the same time, the floating piston 1403 automatically adjusts the volume balance of the chambers on both sides according to the pressure change in the liquid storage cylinder 1400 to maintain the stability of the system; the sealing plug 1402 ensures the airtightness of the liquid storage cylinder 1400 to prevent fluid leakage, and the guide rod 1401 continuously provides stability for the movement of the sleeve 1410 to ensure the smooth operation of the entire system under high-load working conditions; In summary, the system achieves precise control of the movement of the hedging plate 150 and effective protection of the mold body 13 through the coordinated work of carefully designed mechanical and hydraulic components, minimizes the impact of shock and vibration, improves production efficiency and product quality, and also ensures the long-term stability and reliability of the equipment.
