Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and in particular to a moving die for manufacturing the front bulkhead of a new energy vehicle body. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the requirements for manufacturing precision and efficiency of vehicle body parts are constantly increasing. As an important structural component of the new energy vehicle body, the forming quality of the front bulkhead directly affects the safety performance and assembly precision of the entire vehicle. Currently, the moving molds used to manufacture the front bulkheads of new energy vehicle bodies typically include multiple components such as a base, support block, positioning block, and pressure block. The assembly and positioning of the mold are achieved through complex mating relationships between these components.

[0003] However, the existing moving molds have the following shortcomings: First, the assembly and positioning accuracy of the various parts of the mold is insufficient, resulting in a large deviation in the forming size of the front panel, which affects product quality; Second, the design of the mold's support structure and positioning structure is not reasonable enough, and it is prone to loosening and wear during long-term use, reducing the mold's service life; Third, the mold's venting structure is not perfect, and gas cannot be discharged in time during the stamping process, which can easily lead to defects such as air holes and wrinkles on the product surface. Summary of the Invention

[0004] The purpose of this invention is to provide a technical solution for manufacturing a moving mold for the front bulkhead of a new energy vehicle body, addressing the shortcomings of existing technologies. By optimizing the fit structure between the base, side support block, central support block, first positioning block, side pressure block, bracket, top cover, and connecting block, the assembly accuracy and molding quality of the mold are improved, and the service life of the mold is extended.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A moving mold for manufacturing the front bulkhead of a new energy vehicle body, characterized in that it comprises:

[0007] The base has a first placement cavity, a second placement cavity, a reverse side groove, and an operating side groove. The second placement cavity is connected to the reverse side groove and the operating side groove through the first placement cavity.

[0008] The top side support block is set in the second placement cavity, and the top of the base is provided with a top cover limiting groove on the opposite side of the second placement cavity.

[0009] A central support block is disposed in the first placement cavity. The central support block is provided with a first mounting groove, a second mounting groove, a reverse mounting groove, an operating side mounting groove, and a mating groove. The two first mounting grooves are connected by an empty groove. The reverse mounting groove and the operating side mounting groove are respectively connected to the first mounting grooves on both sides. The second mounting groove is located above the first mounting groove. The mating groove is located above the second mounting groove. A first support part protruding from the mating groove is provided between the two second mounting grooves.

[0010] Two first positioning blocks are spliced ​​together and connected to the top-side support block;

[0011] Two lateral pressure blocks are symmetrically arranged in the reverse side mounting groove and the operating side mounting groove;

[0012] A bracket is disposed in the second mounting slot and the first support portion;

[0013] The top cover is assembled into the mating groove and the top cover limiting groove;

[0014] And a connecting block, which connects the lateral pressure block, the bracket and the first positioning block.

[0015] The precise positioning of the main structure of the mold is achieved through the cooperation and installation of the first and second placement cavities on the base with the central support block and the top side support block; the reverse side groove and the operating side groove correspond to the reverse side and operating side direction of the mold, respectively, which facilitates the orientation installation of the mold on the stamping equipment; the first mounting groove, the second mounting groove, the reverse side mounting groove, the operating side mounting groove and the mating groove on the central support block form a multi-level installation and positioning system, which, together with the setting of the first support part, can effectively support the bracket and transmit the stamping force, thereby improving the overall structural strength and assembly accuracy of the mold.

[0016] Furthermore, the first placement cavity is provided with a protrusion and a first groove, with two first grooves located on both sides of the protrusion. The bottom of the central support block is provided with a through groove and a contact surface, with the contact surface located on both sides of the through groove. The protrusion matches the through groove, and the contact surface matches the first groove. By providing a protrusion and a first groove in the first placement cavity of the base, and providing a corresponding through groove and contact surface at the bottom of the central support block, a positioning structure with a concave-convex fit is formed. The protrusion, embedded in the through groove, plays a central positioning role, and the matching of the contact surface with the first groove further restricts the horizontal displacement of the central support block, ensuring the installation accuracy and stability of the central support block within the base.

[0017] Furthermore, the top-side support block is provided with a first through hole and a second through hole, with the two first through holes symmetrically arranged on both sides of the second through hole. A stop block is provided on the top-side support block, and a third through hole is provided on the stop block, located between the first and second through holes. A first assembly cavity is provided on the end face of the top-side support block, and the first, second, and third through holes all connect to the assembly cavity. Lateral chambers are symmetrically arranged on both sides of the top-side support block. The arrangement of the first, second, and third through holes on the top-side support block forms multiple guiding and installation channels, facilitating the installation with other components. The first assembly cavity provides space for the assembly of the first positioning block. The symmetrical arrangement of the lateral chambers is beneficial for the lateral positioning of the top-side support block within the base and for balancing force transmission.

[0018] Furthermore, it also includes a pressure plate. The bottom of the pressure plate is provided with a first arc groove and a second arc groove. The first arc groove matches the first through hole and moves along the outer surface of the first through hole. The diameter of the second arc groove matches the diameter of the third through hole. Side plates are provided on the pressure plate, and the two side plates cooperate to form an inclined channel. A fixing part is integrally formed on one side of the top of the top support block. The fixing part is located on the side away from the first assembly cavity and is provided with a lateral channel. A partition is provided in the lateral channel, and the partition matches the inclined channel. The pressure plate moves along the outer surface of the first through hole through the first arc groove, realizing the guiding sliding of the pressure plate on the top support block. The cooperation between the second arc groove and the third through hole further improves the stability of the pressure plate movement. The cooperation between the inclined channel and the partition allows the pressure plate to slide along a preset trajectory during movement, ensuring reliable clamping of the mold component by the pressure plate.

[0019] Furthermore, it also includes a tray, which is detachably connected to the top-side support block. A locking block is provided on one side of the bottom of the tray, and a second groove is provided between the block and the first through hole. The tray matches the second groove, and a locking slot is provided within the second groove. The locking block matches the locking slot. The tray achieves a snap-fit ​​connection with the top-side support block through the locking block and the locking slot in the second groove, facilitating the disassembly, assembly, and maintenance of the mold. The matching of the tray with the second groove ensures the positional accuracy of the tray after installation.

[0020] Furthermore, it also includes an auxiliary block, which is connected to the first mounting groove and cooperates with the first positioning block and the connecting block. The top of the auxiliary block is provided with a mating block and a fourth core. As an intermediate component connecting the first positioning block and the connecting block, the auxiliary block, through the setting of the mating block and the fourth core, can form and position specific areas of the front bulkhead, thereby improving the mold's ability to form front bulkheads with complex shapes.

[0021] Furthermore, a second assembly cavity is provided on the side of the first positioning block near the top-side support block. The second assembly cavity has a first positioning strip and a second positioning strip extending outwards, with the second positioning strip positioned above the first positioning strip. Both the first and second positioning strips are embedded in the first assembly cavity. The first positioning block is embedded into the first assembly cavity of the top-side support block via the first and second positioning strips, forming a double-strip embedded positioning structure. This effectively improves the connection strength and positioning accuracy of the first positioning block on the top-side support block, preventing displacement during the stamping process.

[0022] Furthermore, a trapezoidal groove is provided at the bottom of the first positioning block, and a first trapezoidal protrusion is provided on the side of the central support block near the top support block. The first trapezoidal protrusion matches the trapezoidal groove, and a second trapezoidal protrusion is provided between the first trapezoidal protrusion and the empty groove. The cooperation between the trapezoidal groove and the first trapezoidal protrusion forms a trapezoidal self-locking positioning structure, which can effectively limit the displacement of the first positioning block in the vertical direction; the setting of the second trapezoidal protrusion further enhances the support and positioning effect of the central support block on the first positioning block.

[0023] Furthermore, a base block and a third support portion are respectively provided on the upper and lower inner sides of the lateral pressure block. The third support portion matches the reverse side mounting groove and the operating side mounting groove, and a first core is provided on the inner surface of the base block. The lateral pressure block is embedded into the reverse side mounting groove and the operating side mounting groove through the third support portion, realizing the stable installation of the lateral pressure block on the central support block; the first core on the inner surface of the base block is used to form the lateral forming surface of the front bulkhead, ensuring the forming accuracy of the side structure of the front bulkhead.

[0024] Furthermore, a second support portion is provided at the bottom of the bracket, which matches the second mounting groove. The two second support portions cooperate to form a transverse groove, which matches the first support portion. The bracket is embedded into the second mounting groove through the second support portion, realizing the positioning and installation of the bracket on the central support block; the cooperation between the transverse groove and the first support portion forms a transverse limiting structure, effectively preventing the bracket from shifting laterally during the stamping process.

[0025] Furthermore, a second positioning groove is provided at the bottom of the second support, and a second positioning block is provided in the second mounting groove, with the second positioning block matching the second positioning groove. The cooperation between the second positioning block and the second positioning groove forms an independent positioning structure, which further improves the installation accuracy of the bracket in the second mounting groove and ensures that the bracket will not shift or shake when subjected to impact pressure.

[0026] Furthermore, the top cover is assembled from two individual top cover units. The bottom surface of each unit matches the mating groove and the top cover limiting groove. A third positioning block is provided within the mating groove, and a third positioning groove is provided on the bottom surface of each unit. The third positioning block matches the third positioning groove. The top cover is assembled from two individual units, facilitating its installation and disassembly. The cooperation between the third positioning block and the third positioning groove ensures the accurate positioning of each unit within the mating groove and the top cover limiting groove, guaranteeing the overall precision of the assembled top cover.

[0027] Furthermore, it also includes a circular cover, with two top cover units fitting together to form a circular hole. The circular cover matches the circular hole, and a stop block is provided inside the circular hole. A stop groove is provided on the side of the circular cover, and the stop block matches the stop groove. The circular cover is used to seal the circular hole between the two top cover units, and the fit between the stop block and the stop groove prevents the circular cover from rotating during use, ensuring the reliability of the circular cover's installation.

[0028] Furthermore, a positioning cavity is provided at the bottom of the circular cover, a first limiting part is provided in the limiting groove of the top cover, and a second limiting part is provided in the mating groove. The first and second limiting parts are spliced ​​together and embedded into the positioning cavity. The spliced ​​first and second limiting parts are embedded into the positioning cavity at the bottom of the circular cover, forming a bidirectional limiting structure for the circular cover, which further improves the installation stability and positional accuracy of the circular cover.

[0029] Furthermore, a first mating surface and a second core are respectively provided on both sides of the bottom of the connecting block, and a second mating surface and a third core are provided on the other side of the first positioning block. The second mating surface matches the first mating surface. The connecting block achieves precise docking between the connecting block and the first positioning block by fitting the first mating surface with the second mating surface of the first positioning block. The second core and the third core are used to form the molding surfaces of different areas of the front bulkhead, ensuring the consistency of the overall structure of the front bulkhead.

[0030] Furthermore, the base has symmetrically arranged cantilever grooves on one side near the second placement cavity, and cantilever blocks are connected to the cantilever grooves. The front and rear sides of the cantilever blocks are respectively provided with a first mounting surface and a second mounting surface. The first mounting surface matches the cantilever groove and has mounting holes, while the second mounting surface has a fourth through hole. A step is provided on the inner side of the cantilever block. The cantilever block connects to the base through the cooperation of the first mounting surface and the cantilever groove. The mounting holes facilitate the fixing of the cantilever block to the base. The fourth through hole on the second mounting surface is used to connect external components. The stepped structure enhances the structural strength of the cantilever block.

[0031] Furthermore, both the reverse side groove and the operating side groove are provided with a first positioning groove. The first positioning groove is used to cooperate with the positioning pin on the stamping equipment to achieve rapid and accurate positioning of the mold on the stamping equipment, thereby improving the efficiency and accuracy of mold installation.

[0032] Furthermore, it also includes a moving mold reverse venting block and a moving mold operating side venting block, both of which are connected to the base via venting pipes. The connection between the moving mold reverse venting block and the moving mold operating side venting block and the base via venting pipes enables timely discharge of gas from the mold cavity during the stamping process, preventing defects such as air holes and wrinkles on the product surface and improving the forming quality of the front panel.

[0033] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0034] 1. The present invention achieves precise positioning of the main structure of the mold by cooperating and installing the first placement cavity and the second placement cavity on the base with the central support block and the top side support block; the multi-level installation and positioning system on the central support block, together with the setting of the first support part, improves the overall structural strength and assembly accuracy of the mold.

[0035] 2. The present invention ensures the installation accuracy and stability of the central support block in the base by the cooperation of the protrusion and the through groove, and the contact surface and the first groove; the cooperation of the trapezoidal groove and the trapezoidal protrusion forms a trapezoidal self-locking structure, which effectively restricts the displacement of the component in the vertical direction.

[0036] 3. The present invention achieves precise positioning and reliable connection between various components of the mold through the guiding sliding structure of the pressure plate, the detachable snap-fit ​​structure of the support plate, and the cooperation between each positioning block and the positioning groove, thereby extending the service life of the mold.

[0037] 4. The present invention, through the structure of the moving mold back side venting block and the moving mold operating side venting block combined with the venting pipe, can timely discharge the gas in the mold cavity during the stamping process, avoid defects such as air holes and wrinkles on the product surface, and improve the forming quality of the front panel.
