Description

Technical Field

[0001] The present application relates to the field of molds, and in particular to a mold for die-casting a pedal bracket for a vehicle. Background Art

[0002] The pedal bracket is one of the vehicle parts, which is connected to the switches of each control unit to control the control unit, and the pedal is integrally cast with the die-casting die. The die-casting die is a tool for casting metal parts, a tool that completes the die-casting process on a dedicated die-casting forging machine.

[0003] The die-casting mold of the vehicle pedal bracket mainly includes an upper mold and a lower mold. The lower mold is provided with a die-casting groove adapted to the vehicle pedal bracket, and the upper mold is provided with a matching column adapted to the through hole of the vehicle pedal bracket. After the upper mold and the lower mold are combined, a cavity adapted to the vehicle pedal bracket is formed. The molten metal then enters the cavity, and after the molten metal is cooled, the vehicle pedal bracket can be formed.

[0004] Since there are many types of vehicle pedal brackets, the existing upper mold and lower mold are usually cast as one piece. When different types of vehicle pedal brackets need to be cast, different types of molds need to be used. The upper mold and lower mold are heavy, and it is cumbersome to replace the entire mold, so there is room for improvement. Utility Model Content

[0005] In order to improve the above problems, the present application provides a die for die-casting a pedal bracket for a vehicle.

[0006] The present application provides a die for die-casting a pedal bracket for a vehicle, which adopts the following technical solution:

[0007] A die for die-casting a pedal bracket for a vehicle comprises a first die and a second die, wherein a first mounting groove is provided on a side of the first die close to the second die, a first module is detachably connected to the first mounting groove, a casting groove matching the pedal bracket for a vehicle is provided on the first module, a second mounting groove is provided on a side of the second die close to the first die, a second module is detachably connected to the second mounting groove, a casting column matching the pedal bracket for a vehicle is provided on the second module, and the first module and the first die, as well as the second module and the second module, are connected via a connecting assembly.

[0008] By adopting the above technical solution, when it is necessary to die-cast the vehicle pedal bracket, the worker selects the first module and the second module that are compatible with the vehicle pedal bracket model, and then puts the first module into the first installation groove and the second module into the second installation groove. The worker then uses the connecting component to fix the first module to the first mold and the second module to the second mold to complete the fixation of the first module and the second module. Under the action of the connecting component, the installation of the first module and the second module is facilitated, and when it is necessary to adapt to different models of vehicle pedal brackets, the steps of workers directly disassembling the first mold and the second mold are reduced, saving some time, thereby improving the efficiency of workers using molds to die-cast the vehicle pedal bracket.

[0009] Preferably, the connecting assembly includes a guide plate and a mounting plate, a guide plate is correspondingly arranged on the first module and the second module, the mounting plate is arranged on the guide plate at the corresponding position, the first mold and the second mold are provided with a makeshift groove, the guide plate is arranged in the makeshift groove at the corresponding position, the first mold and the second mold are provided with a fixing groove connected to the makeshift groove, the mounting plate is arranged in the fixing groove at the corresponding position, a fixing plate is arranged in the fixing groove, the fixing plate is abutted against the mounting plate at the corresponding position, and the fixing plate is connected to the first mold at the corresponding position or the second mold at the corresponding position through bolts.

[0010] By adopting the above technical solution, when workers install the first module or the second module, they insert the first module into the first installation slot or insert the second module into the second installation slot, at which time the guide plate is inserted into the clearance slot and the installation plate is inserted into the fixing slot. The workers then insert the fixing plate into the fixing slot at the corresponding position, so that the fixing plate abuts against the installation plate at the corresponding position, and then use bolts to fix the fixing plate to the first mold at the corresponding position or the second mold at the corresponding position to complete the installation of the first module and the second module, which provides convenience for the subsequent die-casting of the pedal bracket for the vehicle.

[0011] Preferably, the bottoms of the first installation groove and the second installation groove are both provided with positioning columns, and the first module and the second module are both provided with positioning grooves, and the positioning columns are arranged in the positioning grooves.

[0012] By adopting the above technical solution, when workers install the first module or the second module, the first module is inserted into the first installation groove and the second module is inserted into the second installation groove. At this time, the positioning column provides guidance and positioning for the first module or the second module at the corresponding position to determine the position of the first module and the second module, thereby improving the position accuracy between the first module and the first mold and the position accuracy between the second module and the second mold.

[0013] Preferably, the first mold is provided with a guide column, the second mold is provided with a guide groove, and the guide column is slidably connected in the guide groove.

[0014] By adopting the above technical solution, during the process of closing the first mold and the second mold, the guide column enters the guide groove. At this time, the guide column cooperates with the guide groove and provides guidance and limitation for the first mold and the second mold, thereby improving the position accuracy between the first mold and the second mold, thereby facilitating the subsequent formation of the vehicle pedal bracket.

[0015] Preferably, a buffer cylinder is provided on the first mold, a buffer assembly is provided in the buffer cylinder, and a buffer rod matched with the buffer assembly is provided on the second mold, and the buffer rod is slidably connected in the buffer cylinder.

[0016] By adopting the above technical solution, when the first mold and the second mold are closed, the buffer rod enters the buffer cylinder and contacts the buffer assembly, and the buffer rod cooperates with the buffer cylinder and provides further guidance for the first mold and the second mold, further improving the position accuracy between the first mold and the second mold. At the same time, the buffer assembly provides buffering for the buffer rod, that is, provides buffering for the first mold and the second mold, reducing the collision force when the first mold and the second mold are closed, so that the first mold and the second mold are not easily damaged.

[0017] Preferably, the buffer assembly comprises a buffer block and a spring, the buffer block is slidably connected in the buffer cylinder, one end of the spring is connected to the bottom of the buffer cylinder, and the other end is connected to the buffer block.

[0018] By adopting the above technical solution, the buffer rod enters the buffer cylinder and contacts the buffer block. When the buffer rod continues to move, the buffer rod drives the buffer block to move along the buffer cylinder, so that the spring is in a compressed state. At this time, under the elastic force of the spring, part of the pressure of the buffer rod is absorbed, that is, part of the collision force when the second mold and the first mold are closed, thereby reducing the possibility of damage to the first mold and the second mold when they are closed.

[0019] Preferably, a buffer pad is provided on the side of the buffer block facing away from the spring.

[0020] By adopting the above technical solution, the buffer rod is in contact with the buffer pad, and the buffer pad disperses part of the impact force of the buffer rod on the buffer block, making it difficult for the buffer rod to come into hard contact with the buffer block, reducing the wear of the buffer rod and the buffer block, thereby extending the service life of the buffer rod and the buffer block.

[0021] Preferably, a heat insulating sleeve is provided in the buffer cylinder, and the buffer block is slidably connected to the inner wall of the heat insulating sleeve.

[0022] By adopting the above technical solution, the heat insulating sleeve makes it difficult for external heat to be directly transferred to the buffer cylinder, thereby reducing the possibility that the high temperature generated during the production of the vehicle pedal bracket will affect the elasticity of the spring.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the first module, the second module and the connecting assembly, the connecting assembly facilitates the first module to be fixed on the first mold or the second module to be fixed on the first mold, so that the first mold and the second mold are adapted to different models of vehicle pedal brackets. At the same time, the steps of directly disassembling the first mold and the second mold when the model of the vehicle pedal bracket is changed are reduced, saving some time, thereby improving the efficiency of the mold die-casting vehicle pedal bracket;

[0025] 2. By setting a guide column, the guide column provides guidance when the first mold and the second mold are closed, thereby improving the position accuracy between the first mold and the second mold, thereby improving the yield rate of the vehicle pedal bracket die-cast by the first mold and the second mold;

[0026] 3. By providing a buffer component, the buffer component cooperates with the buffer rod to disperse part of the collision force when the first mold and the second mold are closed, so that the first mold and the second mold are not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a die for die-casting a pedal bracket for a vehicle. Figure 1 and Figure 2A die for die-casting a pedal bracket for a vehicle, comprising a first die 1 and a second die 2. A first mounting groove 11 is provided on the side of the first die 1 close to the second die 2, a first module 3 is detachably connected to the first mounting groove 11, and a casting groove 31 adapted to the pedal bracket for a vehicle is provided on the first module 3. A second mounting groove 21 is provided on the side of the second die 2 close to the first die 1, a second module 4 is detachably connected to the second mounting groove 21, and a casting column 41 adapted to the pedal bracket for a vehicle is provided on the second module 4. The first module 3 and the first die 1, as well as the second module 4 and the second module 4, are connected by a connecting assembly 5.

[0032] The worker selects the corresponding first module 3 and second module 4 according to the model of the vehicle pedal bracket, and uses the connection component 5 to fix the first module 3 on the first mold 1 at the corresponding position, and the second module 4 on the second mold 2 at the corresponding position, so as to complete the assembly of the first module 3 and the second module 4, which provides convenience for the worker to use the mold to die-cast the vehicle pedal bracket later. The connection component 5 facilitates the installation of the first module 3 and the second module 4 that are compatible with the model of the vehicle pedal bracket, reduces the steps of directly replacing the first mold 1 and the second mold 2, and thus improves the efficiency of the mold die-casting vehicle pedal bracket.

[0033] Reference Figure 1 and Figure 2 The connection assembly 5 includes a guide plate 51 and a mounting plate 52. A guide plate 51 is fixed to each of the first module 3 and the second module 4. The mounting plate 52 is fixed to the guide plate 51 at the corresponding position. The first mold 1 and the second mold 2 are both provided with a clearance groove 6. The guide plate 51 is arranged in the clearance groove 6 at the corresponding position. The first mold 1 and the second mold 2 are both provided with a fixing groove 7 connected to the clearance groove 6. The mounting plate 52 is arranged in the fixing groove 7 at the corresponding position. A fixing plate 71 is arranged in the fixing groove 7. The fixing plate 71 abuts against the mounting plate 52 at the corresponding position. The fixing plate 71 is connected to the first mold 1 at the corresponding position or the second mold 2 at the corresponding position by bolts.

[0034] Positioning columns 8 are fixed to the bottoms of the first installation groove 11 and the second installation groove 21 . Positioning grooves 81 are formed on the first module 3 and the second module 4 . The positioning columns 8 are disposed in the positioning grooves 81 .

[0035] When the first module 3 and the second module 4 need to be installed, the worker inserts the first module 3 into the first installation groove 11 and the second module 4 into the second installation groove 21. During the installation of the first module 3 and the second module 4, the guide plate 51 is inserted into the clearance groove 6, and the positioning column 8 is inserted into the positioning groove 81, providing dual positioning for the first module 3 at the corresponding position or the second module 4 at the corresponding position, so as to determine the position between the first module 3 and the first mold 1 and the position between the second module 4 and the second mold 2, thereby improving the position accuracy between the first module 3 and the first mold 1 and the position accuracy between the second module 4 and the second mold 2. When the first module 3 abuts against the bottom of the first installation groove 11 and the second module 4 abuts against the bottom of the second installation groove 21, the mounting plate 52 abuts against the bottom of the fixing groove 7 at the corresponding position. The worker then inserts the fixing plate 71 into the fixing groove 7 at the corresponding position, so that the fixing plate 71 abuts against the mounting plate 52 at the corresponding position. The worker then uses bolts to fix the fixing plate 71 to the first mold 1 at the corresponding position or the second mold 2 at the corresponding position to complete the installation of the first module 3 and the second module 4, thereby providing convenience for the workers to install the first module 3 and the second module 4.

[0036] When different types of vehicle pedal brackets need to be die-casted later, the worker separates the bolts from the fixing plate 71, and then moves the fixing plate 71 to separate the fixing plate 71 from the fixing groove 7. The worker then separates the first module 3 from the first mold 1, and the second module 4 from the second mold 2, completing the disassembly of the first module 3 and the second module 4, thereby facilitating the disassembly of the first module 3 and the second module 4, and reducing the steps for the worker to directly disassemble the first mold 1 and the second mold 2, saving some time, thereby improving the die-casting efficiency of the mold for the vehicle pedal bracket.

[0037] Reference Figure 1 and Figure 2 The first mold 1 is provided with a guide column 12, and the second mold 2 is provided with a guide groove 22, in which the guide column 12 is slidably connected. During the process of closing the first mold 1 and the second mold 2, the guide column 12 enters the guide groove 22. At this time, the guide column 12 cooperates with the guide groove 22 and provides guidance and limitation for the first mold 1 and the second mold 2, thereby improving the position accuracy between the first mold 1 and the second mold 2, thereby facilitating the subsequent formation of the vehicle pedal bracket.

[0038] Reference Figure 1 and Figure 2 A buffer cylinder 13 is fixed on the first mold 1 , a buffer assembly 14 is arranged in the buffer cylinder 13 , a buffer rod 23 matching with the buffer assembly 14 is arranged on the second mold 2 , and the buffer rod 23 is slidably connected in the buffer cylinder 13 .

[0039] The buffer assembly 14 includes a buffer block 141 and a spring 142 . The buffer block 141 is slidably connected in the buffer tube 13 . One end of the spring 142 is connected to the bottom of the buffer tube 13 , and the other end is connected to the buffer block 141 .

[0040] When the first mold 1 and the second mold 2 are closed, the buffer rod 23 enters the buffer cylinder 13 and contacts the buffer assembly 14. The buffer rod 23 cooperates with the buffer cylinder 13 and provides further guidance for the first mold 1 and the second mold 2, further improving the position accuracy between the first mold 1 and the second mold 2. At the same time, the buffer rod 23 drives the buffer block 141 to move along the buffer cylinder 13, so that the spring 142 is in a compressed state. At this time, under the elastic force of the spring 142, part of the pressure of the buffer rod 23 is absorbed, that is, part of the collision force when the second mold 2 and the first mold 1 are closed, thereby reducing the possibility of damage to the first mold 1 and the second mold 2 when they are closed.

[0041] Reference Figure 1 and Figure 2 A buffer pad 143 is fixed on the side of the buffer block 141 away from the spring 142. The buffer pad 143 is made of rubber, and the rubber is soft in texture, which reduces the collision force between the buffer rod 23 and the buffer block 141, making it difficult for the buffer rod 23 to come into hard contact with the buffer block 141, thereby reducing the wear of the buffer rod 23 and the buffer block 141, thereby extending the service life of the buffer rod 23 and the buffer block 141.

[0042] Reference Figure 1 and Figure 2 A heat insulating sleeve 144 is provided in the buffer tube 13, and the buffer block 141 is slidably connected to the inner wall of the heat insulating sleeve 144. The heat insulating sleeve 144 is made of ceramic fiber heat insulating tiles. The ceramic fiber heat insulating tiles have the characteristics of low density, high temperature resistance, low thermal conductivity and excellent wave transmission performance, so that the high temperature generated during the production of the vehicle pedal bracket is not easy to affect the elasticity of the spring 142.

[0043] The implementation principle of the die for die-casting of a vehicle pedal bracket in an embodiment of the present application is as follows: the connecting component 5 facilitates the installation of the first module 3 and the second module 4 that are compatible with the model of the vehicle pedal bracket, reducing the steps of directly replacing the first mold 1 and the second mold 2, thereby providing convenience for the die-casting of the vehicle pedal bracket.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
