Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a mold for manufacturing automotive decorative grilles. Background Technology

[0002] Car grilles are the central mesh in front of most vehicles, used to prevent damage to interior components from foreign objects while driving, and also for aesthetic purposes and to showcase individuality. Currently, the production process of car grilles involves using molds and methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping to obtain the desired products. In the manufacturing process of car decorative grilles, apart from a very small number of grilles directly machined using high-tech milling processes, car grilles are often mass-produced through stamping and injection molding. This process often requires the use of corresponding molds and production tools.

[0003] For example, Chinese patent CN218803647U discloses a mold for manufacturing carbon fiber car grilles, including a base. A fixing plate is fixedly connected to the center of the top of the base, and a groove is formed at the center of the top of the fixing plate. A mold is fixedly connected inside the groove, and a cavity is set in the center of the mold. A movable plate is movably connected to the bottom of the mold. Screws are set on the left and right sides of the top of the base. This utility model provides a mold for manufacturing carbon fiber car grilles to solve the problem that existing car grille manufacturing molds can only select a single color to produce car grilles during the production process, and cannot select different colors to produce them. This results in a single function and an unattractive appearance. Moreover, during the production of car grilles, it is not convenient to remove the product from the mold, making the process complicated and time-consuming for workers to remove the product. Furthermore, manual removal can easily damage the product.

[0004] This patent has some drawbacks in its use. For example, after the automotive decorative grille is formed by stamping and injection molding, dust accumulates on the mold or in the gaps with continuous use, affecting the quality of the mold when it is demolded. The device in this patent cannot eliminate the adverse effects of dust and particulate impurities on the mold during the production process. In addition, the device uses a motor to control a threaded rod to move the upper and lower molds closer together to achieve the purpose of die casting. However, in actual production, due to problems such as the low precision of the threaded rod, the movement and clamping between molds using the threaded rod has certain defects. In view of this, we propose a mold for manufacturing automotive decorative grilles. Utility Model Content

[0023] The beneficial effects of this utility model are:

[0024] 1. This automotive decorative grille manufacturing mold, by setting up a rectangular groove, telescopic hose, water pipe, high-pressure nozzle, and diversion pipe, uses a water pump in the rectangular groove and inner cavity to supply water, which is then diverted through the diversion pipe and sprayed out through multiple high-pressure nozzles on two water pipes to wash the surfaces of the lower and upper molds. This solves the problem of traditional devices lacking means of cleaning molds. At the same time, the automated cleaning greatly saves labor and improves efficiency.

[0025] 2. This automotive decorative grille manufacturing mold, by setting up a clamping mechanism, allows the lower mold to be easily fixed and disassembled on the upper surface of the support base, greatly saving the time required to replace the lower mold and improving maintenance efficiency. By setting up protective components, using buffer pads for fit and cushioning, and using multiple springs for energy absorption and pressure reduction, it avoids irreversible damage to the lower mold and the clamping mechanism itself due to excessive extrusion pressure during the clamping process, greatly enhancing the protective performance of this device.

[0026] 3. This automotive decorative grille manufacturing mold, through the setting of a moving mechanism, utilizes the cooperation of a support plate and a ball screw to realize the vertical displacement of the cleaning mechanism, and utilizes the cooperation of an electric slide rail and a sliding sleeve to realize the horizontal displacement of the cleaning mechanism.

[0039] Please see Figure 1 - Figure 5 As shown, this embodiment provides a mold for manufacturing automotive decorative grilles, including:

[0040] A base 1 is provided, and a support seat 2 is fixedly installed on the upper surface of the base 1. A support frame 3 with a U-shaped structure is provided directly above the support seat 2, and the support frame 3 is fixed to the base 1. An upper mold 5 is provided between the support frame 3 and the lower mold 4. Hydraulic cylinders 6 are symmetrically arranged on the upper surface of the upper mold 5.

[0041] A clamping mechanism is mounted on the support base 2 and is used to clamp and fix the lower mold 4.

[0042] A liquid storage tank 17 is fixedly installed on the upper surface of the support frame 3. A water pump is fixedly installed inside the liquid storage tank 17. A telescopic hose 18 is fixed to the output end of the water pump. The other end of the telescopic hose 18 passes through the support frame 3 and extends downward. A mounting plate 19 is provided on the periphery of the bottom end of the telescopic hose 18. Water pipes 20 are symmetrically fixed on the upper and lower surfaces of the mounting plate 19. Multiple high-pressure nozzles 21 are fixedly installed on the water pipes 20 in a linear and equidistant manner. A Y-shaped diversion pipe 22 is fixed to the bottom end of the telescopic hose 18. The other two ends of the diversion pipe 22 are respectively connected to the upper and lower water pipes 20.

[0043] A moving mechanism is disposed on the periphery of the mounting plate 19 and is used to control the movement of the mounting plate 19 along the X-axis and Z-axis.

[0044] The foot of the hydraulic cylinder 6 is fixed to the inner top surface of the support frame 3, and the telescopic rod end of the hydraulic cylinder 6 is fixed to the upper surface of the upper mold 5.

[0045] Start hydraulic cylinder 6. The telescopic rod of hydraulic cylinder 6 moves downward and drives the upper mold 5 to move downward. The upper mold 5 cooperates with the lower mold 4 to complete the stamping of the raw material. When the lower mold 4 needs to be replaced, the clamping mechanism is started so that the clamping mechanism no longer clamps the lower mold 4, and then the lower mold 4 can be removed. When the surfaces of the lower mold 4 and the upper mold 5 need to be cleaned, the moving mechanism is started. At this time, the moving mechanism drives the mounting plate 19 to move. The water pump in the liquid storage tank 17 supplies water to the water pipe 20 through the telescopic hose 18 and the diversion pipe 22. The water in the water pipe 20 is sprayed out through multiple high-pressure nozzles 21 and releases high-pressure water jets to rinse the surfaces of the lower mold 4 and the upper mold 5, thereby completing the cleaning of the lower mold 4 and the upper mold 5. After cleaning, the mounting plate 19 is reset by the moving mechanism. Example

[0046] This embodiment provides a mold for manufacturing automotive decorative grilles. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the clamping mechanism includes:

[0047] A rectangular groove 7 is formed on the upper surface of the support base 2. A placement groove 8 is formed inside the support base 2. A motor 9 is fixedly installed in the placement groove 8. The output shaft of the motor 9 passes through the placement groove 8 and extends into the rectangular groove 7. A gear 10 is coaxially connected to the output shaft of the motor 9. A rack 11 is symmetrically meshed on both sides of the gear 10. Fixing plates 12 are symmetrically arranged on the left and right sides of the support base 2. The rack 11 is fixedly connected to the fixing plate 12 on the corresponding side. A protective component is provided on the inner side of the fixing plate 12 for protecting the lower mold 4 during the clamping process.

[0048] When the clamping mechanism is working, motor 9 is started, and the output shaft of motor 9 rotates, driving gear 10 to rotate. When gear 10 rotates, it can drive two racks 11 to work inward or outward simultaneously. Specifically, when gear 10 rotates clockwise, the two fixed plates 12 move outward, and when gear 10 rotates counterclockwise, the two fixed plates 12 move inward. When the two fixed plates 12 move outward, the clamping mechanism no longer clamps the lower mold 4, and the operator can then remove the lower mold 4 from the upper surface of the support base 2. When the fixed plates 12 move inward, the clamping mechanism clamps the lower mold 4, and the lower mold 4 is firmly fixed to the upper surface of the support base 2. During this process, the protective components act as a buffer to absorb energy and prevent the clamping mechanism from rotating excessively and causing irreversible damage to the lower mold 4.

[0049] By setting up a clamping mechanism, the lower mold 4 can be easily fixed and disassembled on the upper surface of the support base 2, which greatly saves the time required to replace the lower mold 4 and improves maintenance efficiency. Example

[0050] This embodiment provides a mold for manufacturing automotive decorative grilles. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the protective components include:

[0051] An extrusion plate 13 is disposed inside the fixed plate 12. A buffer pad 14 is fixedly installed on the side of the extrusion plate 13 near the lower mold 4. Multiple evenly distributed slide rods 15 are fixedly installed on the side of the extrusion plate 13 near the fixed plate 12. The other end of the slide rod 15 passes through the fixed plate 12 and the tail end is threaded to a limit protrusion. A spring 16 is sleeved on the slide rod 15 at the part between the fixed plate 12 and the extrusion plate 13.

[0052] When the fixed plate 12 moves inward, the extrusion plate 13 and the buffer pad 14 also move inward under the action of the fixed plate 12, and the buffer pad 14 comes into contact with the side wall of the lower mold 4. Because the buffer pad 14 is elastic and flexible, it is gradually compressed and pushes the extrusion plate 13 in the opposite direction, causing the extrusion plate 13 to receive the reverse force from the lower mold 4. Under the action of the extrusion plate 13, multiple springs 16 are compressed and deformed, gradually reaching a compressed state. It is worth noting that a square groove is provided on the side of the extrusion plate 13 near the lower mold 4, and multiple evenly distributed pressure sensors are fixedly installed in the groove. This allows for precise measurement of the extrusion force generated during clamping of the lower mold 4, thereby alerting the operator. The motor 9 is shut off in time to prevent it from running continuously and causing the device to be damaged by excessive extrusion pressure. The control panel and alarm module can be fixedly installed on the front side wall of the support base 2 and electrically connected to the pressure sensor. The multiple pressure sensors in this application are connected to the control panel by a bridge wiring method, which is prior art and will not be described in detail here. When the buffer pad 14 is subjected to the reverse force of the lower mold 4, it can transmit pressure to the extrusion plate 13. At this time, the multiple pressure sensors can transmit the pressure data to the control panel and display it to the operator. By observing the control panel, the operator can ensure that the lower mold 4 is clamped and fixed in a suitable and stable clamping range. When the pressure is too high, the alarm module will sound an alarm.

[0053] By setting up protective components, using buffer pads 14 for contact and cushioning, and using multiple springs 16 for energy absorption and pressure reduction, the clamping mechanism is prevented from causing irreversible damage to the lower mold 4 and the clamping mechanism itself due to excessive extrusion pressure during the process of squeezing the lower mold 4, thus greatly enhancing the protective performance of the device. Example

[0054] This embodiment provides a mold for manufacturing automotive decorative grilles. In addition to the technical solutions of the above embodiments, it also has the following technical features: the buffer pad 14 is made of soft rubber, and the buffer pad 14 has anti-slip texture on the side near the lower mold 4.

[0055] Among them, the buffer pad 14 has good elasticity and resilience. When the clamping mechanism stops clamping the lower mold 4, the buffer pad 14 can gradually return to its original shape.

[0056] By setting the buffer pad 14, the protective performance of this device is further improved. By setting anti-slip texture on the buffer pad 14, the anti-slip performance of this device is improved, reducing the possibility of the lower mold 4 falling off. Example

[0057] This embodiment provides a mold for manufacturing automotive decorative grilles. In addition to the technical solutions of the above embodiments, it also has the following technical features: the moving mechanism comprises a horizontal component for controlling the X-axis movement of the mounting plate 19 and a vertical component for controlling the Z-axis movement of the mounting plate 19. The horizontal component includes:

[0058] Two sets of electric slide rails 23 are symmetrically arranged and located on the front and rear sides of the mounting plate 19 respectively. Sliding sleeves 24 are slidably installed on the electric slide rails 23. The two ends of the mounting plate 19 are fixedly connected to the sliding sleeves 24 on both sides.

[0059] In this embodiment, the vertical component includes:

[0060] Two support plates 25 are arranged symmetrically. The two ends of two electric slide rails 23 are fixedly installed on the lower surfaces of the two support plates 25 respectively. A threaded hole is opened in the center of one of the support plates 25. A ball screw 29 is threadedly connected to the threaded hole on the support plate 25. A motor 30 is fixed on the upper surface of the support frame 3. The output shaft of the motor 30 passes through the support frame 3 and extends downward to be coaxially connected to the ball screw 29. A side plate 27 is provided directly below the ball screw 29 and is fixed to the inner wall of the support frame 3. A bearing seat 28 is fixedly installed on the upper surface of the side plate 27. The ball screw 29 is coaxially connected to the bearing seat 28.

[0061] In the initial state, the mounting plate 19 and the multiple high-pressure nozzles 21 located on it are positioned close to the ball screw 29 and above the upper mold 5, thus preventing the cleaning mechanism from affecting the lower mold 4 and the upper mold 5 during operation. When it is necessary to control the movement of the cleaning mechanism, the vertical assembly is activated first. At this time, the second motor 30 is started, and the output shaft of the second motor 30 rotates, driving the ball screw 29 to rotate. Under the action of the thread force, the support plate 25 drives the horizontal assembly and the mounting plate 19 installed on the horizontal assembly to move downward. When the displacement is between the lower mold 4 and the upper mold 5, the high-pressure water pump in the liquid storage tank 17 is activated. The high-pressure water pump pumps the cleaning liquid in the liquid storage tank 17. Water is delivered to the diversion pipe 22 through the telescopic hose 18, and then diverted by the diversion pipe 22 into two diversion pipes 22. It is then sprayed out through multiple high-pressure nozzles 21. Multiple high-pressure nozzles 21 located above the mounting plate 19 spray and clean the upper mold 5, while multiple high-pressure nozzles 21 located below the mounting plate 19 spray and clean the lower mold 4. Then, the electric slide rail 23 is activated. At this time, the sliding sleeve 24 can slide along the electric slide rail 23 from the side near the ball screw 29 to the side of the stabilizing rod 31, so that the spray water can fully spray and rinse different positions of the lower mold 4 and the upper mold 5. After rinsing is completed, the moving mechanism is reset to the initial state.

[0062] By setting up a moving mechanism, the cleaning mechanism can be moved vertically by the cooperation of the support plate 25 and the ball screw 29, and horizontally by the cooperation of the electric slide rail 23 and the sliding sleeve 24. This allows the cleaning mechanism to be fully and effectively cleaned at different positions of the lower mold 4 and the upper mold 5, preventing the lower mold 4 and the upper mold 5 from being affected by dust accumulation on their surfaces after long-term use, which would affect the quality of the products and the production effect. Example

[0063] This embodiment provides a mold for manufacturing automotive decorative grilles. In addition to the technical solutions of the above embodiments, it also has the following technical features: a stabilizing rod 31 is provided on the inner side of the support frame 3 away from the ball screw 29. The top end of the stabilizing rod 31 is fixed to the inner top surface of the support frame 3. The bottom end of the stabilizing rod 31 passes through another support plate 25 and extends downward. A side plate 27 fixed to the inner wall of the support frame 3 is fixed to the bottom end of the stabilizing rod 31.

[0064] When the mounting plate 19 is displaced vertically, the support plate 25 located on the stabilizer bar 31 can also slide freely along the stabilizer bar 31.

[0065] The structural stability of this device is increased by setting up a stabilizing bar 31. Example

[0066] This embodiment provides a mold for manufacturing automotive decorative grilles. In addition to the technical solutions of the above embodiments, it also has the following technical features: a limiting ring 26 with a U-shaped structure is fixed on the periphery of the support plate 25, and the telescopic hose 18 is movably engaged with the limiting ring 26.

[0067] The main body of the telescopic hose 18 passes through the through hole in the limiting ring 26. The limiting ring 26 guides and limits the telescopic hose 18. When the mounting plate 19 moves in the parallel direction, the telescopic hose 18 will not be scraped against the upper mold 5. The inner edge of the limiting ring 26 is rounded, thereby reducing friction between it and the surface of the telescopic hose 18 and extending the service life of the telescopic hose 18.

[0068] By setting the limit ring 26, the telescopic hose 18 in the cleaning mechanism is prevented from contacting and rubbing against the upper mold 5 during the stretching process, which plays a certain protective role for the telescopic hose 18 and the upper mold 5. Example

[0069] This embodiment provides a mold for manufacturing automotive decorative grilles. In addition to the technical solutions of the above embodiments, it also has the following technical features: a cover plate 32 is provided at the top opening of the rectangular groove 7. The cover plate 32 is fixed to the support base 2 by bolts. A plurality of positioning posts 33 are fixed on the upper surface of the support base 2 in a uniform arrangement. The lower surface of the lower mold 4 is provided with positioning holes that are adapted to the positioning posts 33.

[0070] The cover plate 32 can shield the gear 10 and the two racks 11, increasing the aesthetics of the device while effectively protecting them. The lower surface of the cover plate 32 is covered with sealant to prevent water from entering the inner cavity of the rectangular groove 7 through the gap between the cover plate 32 and the side of the rectangular groove 7 during cleaning. The bottom of the placement groove 8 is provided with heat dissipation holes to prevent the motor 9 from accumulating a large amount of heat in the inner cavity of the placement groove 8 during operation. The positioning column 33 plays a preliminary positioning role, assisting the operator in placing and installing the lower mold 4, thus increasing the accuracy of the device.

[0071] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
