Description

Technical Field

[0001] The present application relates to the technical field of automobile manufacturing equipment, and in particular to a die-casting system for automobile battery covers. Background Art

[0002] A mold is a mold or tool used in industrial production to obtain the desired product through injection molding, blow molding, extrusion, die casting, forging, smelting or stamping.

[0003] The battery cover of new energy vehicles is usually made of PVC leather as raw material, which is fixed on the edge of the mold in advance. The PVC leather is adsorbed on the lower mold, sprayed with polyurethane material for foaming, and covered with the upper mold. After die-casting, the parts are taken out manually.

[0004] However, in the actual processing process, since the product position of the workpiece to be processed is not fixed, the workpiece to be processed cannot be accurately positioned when placed, which easily causes the problem of molding deformation. Utility Model Content

[0005] Based on the above-mentioned deficiencies, the present application provides a die-casting system for a car battery cover to improve the positioning problem between the workpiece to be processed and the mold in the related art.

[0006] This application is implemented as follows:

[0007] The example of the present application provides a die-casting system for a car battery cover, which is used to process a workpiece to be processed into a car battery cover, wherein a first clamp is provided on the workpiece to be processed, and the die-casting system for the car battery cover comprises:

[0008] The die-casting mold includes an upper mold and a lower mold. The lower mold is provided with an insert on the side facing the upper mold, and the insert has a second clamp on the side facing the upper mold. The upper mold and the lower mold are used to place the workpiece to be processed, and the first clamp is located on the side of the workpiece to be processed facing the lower mold, so that the first clamp can be selectively clamped with the second clamp.

[0009] In the above implementation process, a first clamp is set on the side of the workpiece to be processed facing the lower mold, and an insert with a second clamp is set on the side of the lower mold facing the workpiece to be processed. When the workpiece to be processed is placed on the lower mold, the first clamp and the second clamp can be used to position the workpiece to be processed. After the upper mold and the lower mold are subsequently closed, the probability of deformation of the workpiece to be processed due to position offset can be reduced, thereby improving the die-casting production quality of the automobile battery cover.

[0010] In an optional embodiment, the lower mold has a cavity for accommodating a workpiece to be processed, and the insert is embedded in the bottom wall of the lower mold located at the cavity, and the top end of the insert does not protrude from the bottom wall.

[0011] In the above implementation process, the insert is embedded in the bottom wall of the lower mold cavity, and the top end of the insert does not protrude from the bottom wall, which can reduce the impact of the insert and its second clamp on the die-casting quality of the workpiece placed in the cavity.

[0012] In an optional embodiment, the workpiece to be processed is provided with a first magnetic component, and the insert further has a second magnetic component. When the first clamping component is clamped with the second clamping component, the first magnetic component and the second magnetic component attract each other.

[0013] In the above implementation process, a second magnetic part is set at the insert, and a first magnetic part is set at the workpiece to be processed. When the first clamping part is clamped with the second clamping part, the adsorption effect between the first magnetic part and the second magnetic part can be utilized to adsorb the workpiece to be processed in the lower mold, thereby reducing the probability of the first clamping part being separated from the second clamping part during the upper mold closing process, further improving the positioning accuracy of the workpiece to be processed, and improving the die-casting quality of the automobile battery cover formed by die-casting the workpiece to be processed.

[0014] In an optional embodiment, the second clamping member includes a positioning hole, and the first clamping member includes a positioning rod that cooperates with the positioning hole.

[0015] In the above implementation process, a positioning hole is set at the second clamping member, and a positioning rod is set at the first clamping member. When the workpiece to be processed needs to be placed in the cavity of the upper mold, the positioning rod can be extended into the positioning hole to achieve positioning of the workpiece to be processed in the cavity.

[0016] In an optional embodiment, the second clamping member includes two positioning holes that are spaced apart from each other, and the first clamping member has two positioning rods corresponding to the two positioning holes one by one.

[0017] In the above implementation process, two spaced positioning holes are set at the second clamp, and two positioning rods corresponding to the two positioning holes are set at the second clamp of the workpiece to be processed. The cooperation between the two positioning rods and the two positioning holes can further improve the placement accuracy of the workpiece to be processed.

[0018] In an optional embodiment, the second magnetic member is disposed between the two positioning holes, and the first magnetic member is disposed between the two positioning rods.

[0019] In the above implementation process, the second magnetic part is set between the two positioning holes, and the first magnetic part is set between the two positioning rods. The adsorption effect of the first magnetic part and the second magnetic part can be utilized to adsorb the workpiece to be processed so that the two positioning rods can be stably extended into the positioning holes for clamping.

[0020] In an optional embodiment, the second card member also includes a card slot, two positioning holes are arranged on the bottom wall of the card slot and are connected to the card slot; a support column is arranged in the card slot, the support column is located between the two positioning holes, and the second magnetic member is arranged on the top of the support column.

[0021] In the above implementation process, two positioning holes are set at the bottom of the slot, and the positioning holes are connected to the slot, so that the positioning rod at the first clamp can pass through the slot and extend into the corresponding positioning hole. The second magnetic member is set in the slot through the support column to prevent the second magnetic member from extending into the cavity.

[0022] In an optional embodiment, the first clamping member includes a boss, the positioning rod and the first magnetic member are arranged on the boss, and the boss can extend into the clamping slot.

[0023] In the above implementation process, the positioning rod and the first magnetic part are both arranged at the boss, and the boss can be extended into the slot, so that the first magnetic part at the boss can fit and adsorb with the second magnetic part in the groove, and the positioning rod can be extended into the positioning hole for snap connection.

[0024] In combination with the first aspect, in an optional embodiment, the lower die is provided with a plurality of inserts at intervals, and the workpiece to be processed is provided with a plurality of first clamping members corresponding one-to-one to the second clamping members.

[0025] In the above implementation process, multiple second clamps are arranged at intervals at the lower mold, and multiple first clamps corresponding to the second clamps are arranged at intervals at the workpiece to be processed, which can further improve the accuracy of the placement position of the workpiece to be processed.

[0026] In an optional embodiment, the die-casting mold further includes a mold frame and a lifting mechanism, the upper mold and the lifting mechanism are arranged on the mold frame, and the lifting mechanism drives the upper mold to move up and down to approach or move away from the lower mold.

[0027] In the above implementation process, the lower mold and the lifting mechanism are both arranged on the mold frame. The lifting mechanism can be used to drive the upper mold to lift and lower the mold to die-cast the workpiece, or after the die-casting is completed, it can rise away from the lower mold to open the mold, so as to facilitate the removal of the die-cast product.

DETAILED DESCRIPTION

[0034] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions.

[0036] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] In the description of the embodiments of the present application, the orientations or positional relationships indicated by technical terms such as "upper", "lower", "bottom", "top", "inside" and "outside" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the embodiments of the present application and simplifying the description. They do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present application.

[0039] In the processing of the battery cover of the new energy vehicle, it is usually necessary to place the workpiece 20, such as PVC skin, in the cavity 111 of the lower mold 11, and then use a robot to spray polyurethane material along a certain trajectory for foaming, and cover the upper mold 12 for die casting. After holding the pressure for a certain period of time, the mold is opened, and then the die-cast product is taken out manually.

[0040] However, when the existing mold is used to process the automobile battery cover and the workpiece 20 is placed in the cavity 111 of the lower mold 11, the actual placement position of the workpiece 20 is prone to deviation, which can easily cause mold deformation after subsequent die-casting, affecting the die-casting quality of the automobile battery cover product.

[0041] Therefore, the present application further improves the automotive battery cover die-casting system 1, thereby improving the accuracy of the placement of the workpiece 20 to be processed to a certain extent and improving the die-casting quality of the automotive battery cover. In order to make the purpose, technical solution and advantages of the embodiment of the present application clearer, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0042] See also Figure 1 The present application example provides a car battery cover die-casting system 1 for processing a workpiece 20 into a car battery cover.

[0043] Please continue reading Figure 1 and Figure 2 The automotive battery cover die-casting system 1 comprises a die-casting die 10. The die-casting die 10 comprises a lower die 11 and an upper die 12. The lower die 11 is provided with an insert 13 on one side facing the upper die 12. The insert 13 is provided with a second clamp 131 on one side facing the upper die 12.

[0044] The workpiece 20 to be processed is placed between the lower die 11 and the upper die 12 .

[0045] A first clamping member 21 is provided on a side of the workpiece 20 facing the lower die 11 .

[0046] A first clamping member 21 is provided on the side of the workpiece 20 facing the lower die 11, and an insert 13 having a second clamping member 131 is provided on the side of the lower die 11 facing the workpiece 20. When the workpiece 20 is placed on the lower die 11, the first clamping member 21 and the second clamping member 131 can be used to clamp the workpiece 20 to be positioned. After the upper die 12 and the lower die 11 are subsequently combined for die casting, the probability of deformation of the workpiece 20 due to the offset of the placement position can be reduced, thereby improving the die-casting production quality of the automobile battery cover.

[0047] The die-casting mold 10 and the workpiece 20 in the automotive battery cover die-casting system 1 provided in the embodiment of the present application are further described in detail below in conjunction with the accompanying drawings.

[0048] The die-casting mold 10 has a lower mold 11 and an upper mold 12, and the workpiece 20 is placed between the lower mold 11 and the upper mold. After the workpiece 20 is placed on the lower mold 11, the upper mold 12 is pressed down on the lower mold 11, and the molds are closed, so that the workpiece 20 can be die-cast into a car battery cover with a set structure.

[0049] The present application does not limit the specific structure of the lower mold 11 and the upper mold 12. In some possible embodiments, please continue to refer to Figure 1 The lower die 11 is a concave die, and is provided with a cavity 111 for accommodating the workpiece 20 to be processed.

[0050] The upper mold 12 is a male mold, and is provided with a boss that can extend into the mold cavity 111. Alternatively, the upper mold 12 is not provided with a boss, and the upper mold 12 can be directly covered on the mold cavity 111 of the lower mold 11.

[0051] Furthermore, in some possible embodiments, corresponding patterns may be provided in the cavity 111 of the lower mold 11 .

[0052] Further, in some possible embodiments, please continue to refer to Figure 1 The die-casting mold 10 is also provided with a mold frame 14 .

[0053] Exemplarily, the mold frame 14 includes four columns, and the four columns are connected by top beams and bottom beams to form a rectangular parallelepiped frame structure.

[0054] Furthermore, in order to facilitate setting the lower mold 11 on the mold frame, in some possible embodiments, a plurality of lower support beams can be provided at the bottom of the rectangular parallelepiped frame, and the lower mold 11 can be fixed on the support beams.

[0055] Alternatively, continue to Figure 1 The mold frame 14 can be set as a mounting platform, and the lower mold 11 can be installed on the mounting platform.

[0056] Furthermore, in order to facilitate closing the upper mold 12 close to the lower mold 11 and opening the upper mold 12 away from the lower mold 11, in some possible embodiments, the die-casting mold 10 may also be provided with a lifting mechanism (not shown in the figure).

[0057] For example, the lifting mechanism can drive the upper mold 12 to rise and fall via a hydraulic press.

[0058] Furthermore, in order to facilitate the arrangement of the lifting mechanism above the lower mold 11 so as to utilize the lifting mechanism to drive the upper mold 12 to move up and down, in some possible embodiments, multiple upper support beams can be arranged above the mounting table, and the lifting mechanism can be fixed on the support beams. At the same time, the output shaft of the lifting mechanism can pass downward through the gaps between the multiple upper support beams, so that the output shaft can be connected to the upper mold 12 and drive the upper mold 12 to move up and down.

[0059] Furthermore, in order to improve the movement stability of the upper mold 12, a guide mechanism (not shown in the figure) can be provided at the upper mold 12. The guide mechanism includes a connecting plate, and the connecting plate is slidably connected to the column of the mold frame 14.

[0060] In order to facilitate the placement of the workpiece 20 at a fixed position in the cavity 111, the die-casting mold 10 provided in the example of the present application is provided with an insert 13. The insert 13 is provided on the lower mold 11, and a second clamp 131 is provided on the side of the insert 13 facing the upper mold 12. A first clamp 21 is provided on the side of the workpiece 20 facing the lower mold 11. When the workpiece 20 is placed on the lower mold 11, the first clamp 21 at the workpiece 20 can be clamped with the second clamp 131 at the insert 13 of the lower mold 11, so as to realize the positioning of the workpiece 20 at the lower mold 11.

[0061] Exemplarily, the insert 13 is embedded in the bottom wall 112 of the cavity 111 of the lower mold 11 , and the top of the insert 13 does not protrude from the bottom wall 112 .

[0062] The top of the insert 13 does not protrude from the bottom wall, which can reduce the structural impact of the insert 13 on the workpiece 20 during die-casting.

[0063] In order to facilitate the cooperation between the first clamp 21 and the second clamp 131 to achieve the positioning of the workpiece 20 to be processed, in some possible embodiments, the second clamp 131 may be provided with a column for positioning, and the first clamp 21 includes a socket that cooperates with the column.

[0064] A socket is provided at the workpiece 20. In the die-casting system of the automobile battery cover obtained after the die-casting of the workpiece 20, the socket cannot be removed, which easily affects the quality of the automobile battery cover. Even if the socket is filled, the bonding force between the filling material and the body of the workpiece 20 is weak, which easily affects the structural stability of the automobile battery cover.

[0065] Or, in some other possible embodiments, please combine Figure 2 , Figure 3 and Figure 4 The second clamping member 131 may be provided with a positioning hole 1311 , and the first clamping member 21 includes a positioning rod 211 matched with the positioning hole 1311 .

[0066] Exemplarily, a positioning hole 1311 is provided on the side of the insert 13 facing the upper die 12 , and a protruding positioning rod 211 is provided on the side of the workpiece 20 facing the lower die 11 . The positioning rod 211 is extended into the positioning hole 1311 to achieve positioning of the workpiece 20 .

[0067] A protruding positioning rod 211 is provided at the first clamping member 21 of the workpiece 20 to be processed. During the die-casting process, the positioning rod 211 extends into the positioning hole 1311 of the second clamping member 131. The protruding positioning rod 211 does not affect the die-casting process of the workpiece 20 to be processed. After die-casting, the positioning rod 211 at the die-cast product can be cut and removed to improve the appearance quality of the automobile battery cover.

[0068] Furthermore, a plurality of spaced positioning holes 1311 may be provided on the side of the insert 13 facing the upper mold 12, and a plurality of positioning rods 211 corresponding to the positioning holes 1311 may be provided on the side of the first clamping member 21 of the workpiece 20 facing the lower mold 11, and the plurality of positioning rods 211 may be extended one-to-one into the plurality of positioning holes 1311, thereby further improving the positioning accuracy of the workpiece 20 to be processed.

[0069] For example, please refer to Figure 4 Two positioning rods 211 are provided on the side of the first clamping member 21 of the workpiece 20 facing the lower mold 11 .

[0070] Further, a plurality of second clamps 131 may be provided on the side of the lower die 11 facing the upper die 12, and a plurality of positioning holes 1311 may be provided at each second clamp 131. A plurality of first clamps 21 corresponding to the second clamps 131 may be provided on the side of the workpiece 20 facing the lower die 11, and each first clamp 21 may be provided with a positioning rod 211 corresponding to the positioning hole 1311.

[0071] For example, please refer to Figure 2 Two first clamping members 21 are arranged on the side of the workpiece 20 facing the lower die 11 , and each first clamping member 21 is provided with two positioning rods 211 corresponding to the positioning holes 1311 one by one.

[0072] Further, in some possible embodiments, please combine Figure 2 , Figure 3 and Figure 4 The second clamping member 131 further comprises a clamping slot 1312, and two positioning holes 1311 are arranged on the bottom wall of the clamping slot 1312 and communicate with the clamping slot 1312. The first clamping member 21 comprises a boss 212, and the positioning rod 211 is arranged on the boss 212, and the boss 212 can extend into the clamping slot 1312.

[0073] The boss 212 in the first clamping member 21 is inserted into the clamping groove 1312 of the second clamping member 131, which can further improve the accuracy of the placement of the workpiece 20 to be processed. The positioning hole 1311 is arranged on the bottom wall of the clamping groove 1312 and communicates with the clamping groove 1312. After the boss 212 is inserted into the clamping groove 1312, the positioning rod 211 can further be inserted into the positioning hole 1311 at the bottom wall of the groove.

[0074] Further, in some possible embodiments, please continue to combine Figure 3 and Figure 4 The workpiece 20 is also provided with a first magnetic member 22, and the insert 13 is also provided with a second magnetic member 132. When the first clamping member 21 is clamped with the second clamping member 131, the first magnetic member 22 and the second magnetic member 132 are attracted to each other.

[0075] A second magnetic component 132 is provided at the insert 13, and a first magnetic component 22 is provided at the workpiece 20 to be processed. When the first clamping component 21 is clamped with the second clamping component 131, the first magnetic component 22 and the second magnetic component 132 can be used to adsorb the workpiece 20 to be processed at the lower mold 11 through the adsorption effect of opposite charges, thereby reducing the probability of the first clamping component 21 being squeezed out of the second clamping component 131 during the closing process of the upper mold 12, further improving the positioning accuracy of the workpiece 20 to be processed, and improving the die-casting quality of the automobile battery cover formed by the die-casting of the workpiece 20 to be processed.

[0076] Further, in some possible embodiments, see Figure 4 , the first magnetic member 22 can be arranged between the two positioning rods 211. Figure 3 , the second magnetic member 132 is disposed between the two positioning holes 1311 .

[0077] Exemplarily, when the positioning holes 1311 are disposed on the bottom wall of the slot 1312 , the second magnetic member 132 may be disposed at a position of the bottom wall of the slot 1312 corresponding to between the two positioning holes 1311 .

[0078] Exemplarily, when the positioning rods 211 are disposed on the bosses 212 , the first magnetic member 22 may be disposed at a position of the bosses 212 corresponding to a position between the two positioning rods 211 .

[0079] Further, in order to facilitate the second magnetic member 132 disposed at the bottom wall of the slot 1312 to contact and adsorb with the first magnetic member 22 disposed at the boss 212, in a possible embodiment, please continue to refer to Figure 3 A support column 133 can be provided at the slot 1312, and the second magnetic member 132 can be fixed at one end of the support column 133 away from the bottom wall of the slot. The height of the support column 133 is lower than the depth of the slot 1312, so that the second magnetic member 132 does not extend beyond the slot 1312.

[0080] Furthermore, the height of the support column 133 is half of the depth of the slot 1312 , and the first magnetic member 22 is disposed on the surface of the boss 212 , so that the boss 212 can extend into the slot 1312 .

[0081] Alternatively, in another possible embodiment, the top of the second magnetic member 132 disposed at the support column 133 is flush with the top of the slot 1312. In order to facilitate the insertion of the boss 212 into the slot 1312, a mounting hole of a certain depth may be provided at the boss 212, and the first magnetic member 22 may be placed in the mounting hole. When the boss 212 is inserted into the slot 1312, the support column 133 and the second magnetic member 132 may be inserted into the mounting hole to contact and adsorb the first magnetic member 22, and at the same time, the positioning rod 211 is inserted into the positioning hole 1311 at the bottom wall of the slot, so as to realize the positioning of the workpiece 20 to be processed in the cavity 111.
