Description

Technical Field

[0001] The present application relates to the technical field of thermal correction, and in particular to a front axle double-sided thermal correction mold. Background Art

[0002] During the processing of the front axle of the automobile, the workpiece needs to be thermally corrected, that is, the workpiece is subjected to external force or the internal stress state of the steel part is changed in various ways at a certain temperature so that the deformation is corrected. The specific thermal correction operation is to first heat the workpiece in the lower die, and then repeatedly move the upper die downward through the upper die. The upper die and the lower die are attached to each other to achieve the effect of forging the workpiece in the lower die, and then wait for the workpiece to cool down to achieve the effect of correcting the workpiece.

[0003] Two mold cavities are respectively arranged on the two opposite surfaces of the upper mold and the lower mold. The upper mold and the lower mold are a group. The two mold cavities of each group of molds constitute a complete correction cavity, through which the heated workpiece is forged and corrected. Since each group of molds has only one correction cavity and the correction cavities corresponding to different workpieces are also different, each group of molds can only correct one workpiece. If other different workpieces need to be corrected, another group of molds needs to be prepared. In actual production, the price of a group of molds is very expensive. If two groups of molds are prepared because two workpieces need to be corrected, this will undoubtedly increase the manufacturing cost dramatically and reduce the profit.

[0004] In view of the above problems, the present application proposes a front axle double-sided thermal correction mold. Summary of the invention

[0005] An embodiment of the present application provides a front axle double-sided thermal correction mold to solve the problem in the related art that two molds can only thermally correct one workpiece.

[0006] In a first aspect, a front axle double-sided thermal correction mold is provided, comprising:

[0007] Two molds, one of which is provided with at least two different cavities, and the other mold is provided with a matching cavity corresponding to the mold cavity;

[0008] Both of the molds can be used to connect with the upper mold base or the lower mold base. When the two molds are connected with the upper mold base and the lower mold base respectively, the mold cavity on one mold can be opposite to the corresponding matching cavity on the other mold.

[0009] Some embodiments further include at least two dovetail blocks and two dovetail slots;

[0010] At least two dovetail blocks are arranged on the mold, a plurality of the dovetail blocks correspond to a plurality of the cavities one by one, two dovetail grooves are respectively opened on the upper mold base and the lower mold base, and the dovetail blocks can be inserted into the dovetail grooves.

[0011] In some embodiments, two gaps and two filling blocks are further included;

[0012] When the dovetail block is located in the dovetail groove and one side of the dovetail block is close to the side wall of the dovetail groove, the gap is located between the dovetail block and the dovetail groove, the two filling blocks correspond to the two gaps one by one, and the filling blocks can be inserted into the gaps.

[0013] In some embodiments, two limit blocks are further included;

[0014] The two limit blocks are respectively located on the two molds. When the molds are connected to the upper mold base or the lower mold base, the limit blocks limit the filling block from leaving the gap in the vertical direction.

[0015] In some embodiments, there are two different chambers and two different matching cavities on the two molds, respectively. The two chambers are the first chamber and the second chamber, respectively, and the two matching cavities are the first matching cavity and the second matching cavity.

[0016] The first chamber is arranged opposite to the second chamber, the first matching chamber is arranged opposite to the second matching chamber, the first chamber corresponds to the first matching chamber, and the second chamber corresponds to the second matching chamber.

[0017] In some embodiments, the side of the mold where the cavity or the matching cavity is provided is a plane, and the thickness of the edge of the cavity is greater than 1.5 times the depth of the cavity.

[0018] An embodiment of the present application provides a double-sided thermal correction mold for a front axle. Since the present application opens multiple different cavities on one mold and opens multiple corresponding different matching cavities on another mold, each cavity and each corresponding matching cavity can perform thermal correction on a workpiece. Therefore, the present application realizes that two molds can perform thermal correction on multiple workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] The embodiment of the present application provides a front axle double-sided thermal correction mold, which can solve the problem in the related art that two molds can only thermally correct one workpiece.

[0026] See also Figures 1 to 3 A front axle double-sided thermal correction mold 1, comprising: two molds 1, one of which is provided with at least two different cavities 2, and the other mold 1 is provided with a matching cavity 3 that matches the mold cavity; both of the two molds 1 can be used to connect with an upper mold base 4 or a lower mold base 5, and when the two molds 1 are respectively connected with the upper mold base 4 and the lower mold base 5, the mold cavity on one of the molds 1 can be opposite to the corresponding matching cavity 3 on the other mold 1;

[0027] During the implementation process, a plurality of different cavities 2 or matching cavities 3 are opened on the mold 1, and each cavity 2 and each corresponding matching cavity 3 can be combined to thermally calibrate a workpiece. By replacing different mold cavities and corresponding matching cavities 3, the two molds 1 can be thermally calibrated for different workpieces. Compared with the traditional two molds 1 that can only thermally calibrate one workpiece, the present application greatly improves the utilization efficiency of the mold 1 and reduces the thermal calibration cost of the manufacturer.

[0028] Furthermore, in this embodiment, at least two dovetail blocks 6 and two dovetail grooves 7 are also included;

[0029] At least two dovetail blocks 6 are arranged on the mold 1, and a plurality of the dovetail blocks 6 correspond to a plurality of the chambers 2 one by one. Two dovetail grooves 7 are respectively opened on the upper mold base 4 and the lower mold base 5, and the dovetail blocks 6 can be inserted into the dovetail grooves 7;

[0030] It also includes two gaps 8 and two filling blocks 9;

[0031] When the dovetail block 6 is located in the dovetail groove 7 and one side of the dovetail block 6 is close to the side wall of the dovetail groove 7, the gap 8 is located between the dovetail block 6 and the dovetail groove 7, and the two filling blocks 9 correspond to the two gaps 8 one by one, and the filling blocks 9 can be inserted into the gaps 8;

[0032] The steps for installing the mold 1 on the upper mold base 4 or the lower mold base 5 are to first place the dovetail block 6 into the dovetail groove 7, at which time one side of the dovetail block 6 is close to one side of the dovetail groove 7, and a gap 8 is formed between the dovetail block 6 and the dovetail groove 7, and then two filling blocks 9 are respectively inserted into the gap 8 of the upper mold base 4 and the lower mold base 5 to complete the installation of the mold 1.

[0033] Specifically, in this embodiment, two limit blocks 10 are also included;

[0034] The two limit blocks 10 are respectively located on the two molds 1. When the mold 1 is connected to the upper mold base 4 or the lower mold base 5, the limit blocks 10 limit the filling block 9 from leaving the gap 8 in the vertical direction.

[0035] The limiting block 10 covers the vertical opening of the gap 8, so that the filling block 9 cannot slide out of the gap 8 along the vertical direction, thereby preventing the mold 1 in the upper mold base 4 from falling off.

[0036] More specifically, in this embodiment, two different cavities 2 and two different matching cavities 3 are respectively present on the two molds 1, the two cavities 2 are respectively the first cavity 2 and the second cavity 2, and the two matching cavities 3 are respectively the first matching cavity 3 and the second matching cavity 3;

[0037] The first chamber 2 is arranged opposite to the second chamber 2, the first matching chamber 3 is arranged opposite to the second matching chamber 3, the first chamber 2 corresponds to the first matching chamber 3, and the second chamber 2 corresponds to the second matching chamber 3;

[0038] There are two chambers 2 and two matching chambers 3, which facilitates staggered arrangement between chambers 2 and chambers 2 or between matching chambers 3 and matching chambers 3;

[0039] There are also two dovetail blocks 6 corresponding to the chamber 2 and the matching chamber 3. The two dovetail blocks 6 are installed opposite to each other. By installing different dovetail blocks 6 in the dovetail groove 7, the chamber 2 or the matching chamber 3 can be replaced by turning the mold 1 over and installing it.

[0040] Preferably, in this embodiment, the side of the mold 1 provided with the cavity 2 or the matching cavity 3 is a plane, and the edge thickness of the cavity 2 is greater than 1.5 times the depth of the cavity 2;

[0041] The mold 1 has a cavity 2 or a matching cavity 3 on one side which is flat, so that the two molds 1 can be fitted together. The edge thickness of the cavity 2 is greater than 1.5 times the depth of the cavity 2, so that the mold 1 has sufficient structural strength.

[0042] Here’s how this application works:

[0043] Two cavities 2 and two matching cavities 3 are respectively provided on the two molds 1, so that the cavities 2 and cavities 2 or the matching cavities 3 and the matching cavities 3 can be arranged in a staggered manner to improve the strength of the mold 1;

[0044] When different dovetail blocks 6 are installed in the dovetail groove 7 and restricted by the limit block 10 and the filling block 9, different chambers 2 are opposite to their corresponding matching chambers 3, so that the chamber 2 or the matching chamber 3 can be replaced after the mold 1 is turned over and installed.
