Description

Technical field:

[0001] The invention relates to the technical field of magnesium-aluminum alloy automobile parts, and more particularly to a hydraulic heat shaping device for an automobile instrument panel frame with convenient mold disassembly and assembly. Background technology:

[0002] Existing automobile dashboard brackets are generally cast from magnesium-aluminum alloys. Casting is the process of pouring liquid metal into a mold for solidification. Due to factors such as cooling rate and the physical properties of the metal, the geometric accuracy and surface quality of the cast products are relatively poor.

[0003] The existing automobile instrument panel bracket has a high surface precision requirement, so that after the casting is completed, the surface does not need to be processed again. Therefore, some existing methods are to use hydraulic hot shaping to manufacture. Hydraulic hot shaping is a molding method that heats the material to soften it and then applies pressure to it to deform the material into a desired shape. It can meet the high surface precision requirements of the automobile instrument panel bracket. However, in the existing molding mold, the upper mold and the lower mold are both fixed to the connecting plate by bolts, and the connecting plate is then fixed to the mold connector. Due to its heavy weight, it needs to be lifted by a crane. Due to the structure such as the stamping cylinder above the upper mold, it cannot be lowered from the top to the required installation position, but it needs to be lifted and moved to the front or rear of the installation position, and then manually pushed to move it to the installation position, and then installed. After reaching the front or rear of the installation position, it needs to be manually pushed, which is troublesome to install, load and unload, inefficient, and poor in effect.

[0004] Some still directly carry the connecting plate with the upper mold or the lower mold installed to the installation position by multiple people for installation, which has low efficiency, poor effect and large amount of manual labor. Summary of the invention:

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a hydraulic heat shaping equipment for an automobile instrument panel skeleton with convenient mold disassembly and assembly. The equipment can place an upper mold mounting plate with an upper mold and a lower mold mounting plate with a lower mold on a flip support plate. The equipment can automatically move the upper mold mounting plate or the lower mold mounting plate to the corresponding upper heating block or the heating fixing block for installation. The equipment is easy to install and disassemble, and is convenient for crane lifting and placement, which greatly reduces the difficulty of installation and disassembly.

[0028] Figure 5 yes Figure 4 A partial enlarged view of . Specific implementation method:

[0029] For example, see Figures 1 to 5 As shown, a hydraulic heat shaping device for a car instrument panel skeleton with convenient mold disassembly and assembly comprises a forming frame 10 and a mold replacement auxiliary frame 20, an upper support frame 30 is fixed to the top surface of the top plate of the forming frame 10, a heating fixing block 11 is fixed to the middle of the top surface of the top plate of the forming frame 10, a plurality of heating rods 111 are installed in the heating fixing block 11, a lower mold mounting plate 12 is fixed to the top surface of the heating fixing plate 11 by bolts, and a lower mold 13 is fixed to the top surface of the lower mold mounting plate 12 by bolts;

[0030] A molding oil cylinder 31 is fixed to the middle of the top surface of the top plate of the upper support frame 30, the bottom end of the push rod of the molding oil cylinder 31 extends out of the top surface of the top plate of the upper support frame 30 and is fixed with a lifting and fixing plate 32, the bottom surface of the lifting and fixing plate 32 is fixedly connected with an upper heating block 33 by bolts, and a plurality of heating rods 331 are installed in the upper heating block 33;

[0031] The bottom surface of the upper heating block 33 is fixedly connected to an upper mold mounting plate 34 by bolts, and the bottom surface of the upper mold mounting plate 34 is fixedly connected to an upper mold 35 by bolts, and the upper mold 35 corresponds to the lower mold 13 in the upper and lower directions;

[0032] The mold replacement auxiliary frame 20 is located behind the molding frame 10 and fixed on the ground, and the front wall surface of the flip support plate 21 of the mold replacement auxiliary frame 20 is close to the rear wall surface of the molding frame 10 .

[0033] Furthermore, vertical guide columns 14 are fixed to the front and rear of the left and right parts of the top surface of the top plate of the forming machine frame 10, and the bottom end of the vertical guide column 14 is fixed to the top plate of the upper support frame 30. The front and rear of the left and right parts of the lifting and fixing plate 32 are formed with vertical guide through holes, and the outer wall of the guide sleeve is pressed against the inner wall of the corresponding vertical guide through hole. The guide sleeve is fixed on the lifting and fixing plate 11, and the vertical guide column 14 is inserted into the corresponding guide sleeve. The outer wall of the vertical guide column 14 is tightly fitted with the inner wall of the corresponding guide sleeve.

[0034] The top surface of the heating and fixing block 11 is formed with a plurality of dovetail-shaped through grooves 112 extending forward and backward, the top surface of the heating and fixing block 11 is formed with a plurality of dovetail-shaped guide strips 113 extending forward and backward, the bottom surface of the lower mold mounting plate 12 is formed with a plurality of first dovetail-shaped through grooves 121 extending forward and backward and a plurality of first dovetail-shaped guide strips 122 extending forward and backward, the first dovetail-shaped guide strips 122 are inserted into and matched with the corresponding dovetail-shaped through grooves 112, and the dovetail-shaped guide strips 113 are inserted into and matched with the corresponding first dovetail-shaped through grooves 121;

[0035] The above structure increases the contact area between the heating fixed block 11 and the lower mold mounting plate 12, thereby improving the heat conduction effect. In addition, the coordination of the dovetail guide strip 113, the first dovetail guide strip 122, the first dovetail through groove 121, and the dovetail through groove 112 makes it difficult for the two to shift, and the installation and fixing are accurate, which facilitates the subsequent fixing with bolts.

[0037] Similarly, the above structure increases the contact area between the upper heating block 33 and the upper mold mounting plate 34, thereby improving the heat conduction effect. In addition, the cooperation of the second dovetail through groove 331, the second dovetail guide strip 332, the third dovetail through groove 341 and the third dovetail guide strip 342 makes it difficult for the two to shift, and the installation and fixation are accurate, which is convenient for subsequent fixing with bolts.

[0038] Furthermore, the left and right parts of the top surface of the upper heating block 33 are fixed or formed with upwardly extending support blocks 335, the support blocks 335 are inserted into the corresponding vertical through holes on the lifting and fixing plate 32, the upper part of the support block 335 extends out of the top surface of the lifting and fixing plate 32 and is formed with a positioning groove 336 running through the left and right sides, and a pushing cylinder 36 is fixed to the top surface of the lifting and fixing plate 32 at one side of the upper part of the support block 335, and a pushing block 37 is fixed to the end of the push rod of the pushing cylinder 36, and the horizontal part of the pushing block 37 is inserted into the corresponding positioning groove 336.

[0039] A self-lubricating plate 372 is fixed to the bottom surface of the horizontal portion of the push block 37, and a transverse guide bar 325 is fixed to the corresponding position of the top surface of the lifting and fixing plate 32.

[0040] An upper through groove 38 extending left and right is formed on the top plate of the upper support frame 30 above the pushing cylinder 36 and the corresponding support block 335, so that when the lifting and fixing plate 32 is lifted, the pushing cylinder 36 and the corresponding support block 335 will be in the corresponding upper through groove 38, so that they will not collide or interfere with the top plate of the upper support frame 30.

[0041] The above structure is adopted, so that when the upper heating block 33 needs to be disassembled, replaced or repaired, the upper heating block 33 will not fall after the bolts between the upper heating block 33 and the lifting and fixing plate 32 are removed, and the support is achieved by the horizontal parts of the two pushing blocks 37, thereby preventing the upper heating block 33 from falling directly after the bolts between the upper heating block 33 and the lifting and fixing plate 32 are removed, thereby improving the safety effect. Subsequently, it is only necessary to use a forklift or other lifting equipment to extend the horizontal support part to the position directly below the upper heating block 33 and lean it against the top surface of the upper heating block 33, and lift it upward by a small distance to ensure that the top surface of the positioning groove 336 does not lean against the top surface of the horizontal part of the pushing block 37, and then, through the retraction of the push rods of the two pushing cylinders 36, the horizontal part of the pushing block 37 is moved out of the corresponding positioning groove 336. At this time, the upper heating block 33 is completely separated from the lifting and fixing plate 32. At this time, the horizontal support part is lowered by a forklift or other lifting equipment, so that the upper heating block 33 can be removed along with the lowering of the horizontal support part for maintenance or replacement, which is very convenient.

[0056] At the same time, all electrical devices in this embodiment are electrically connected to the control host through electrical connection lines, and their operation is controlled by the control host. This is a conventional structure and will not be described in detail here.

[0057] When this embodiment is in use, the automobile instrument panel bracket casting to be processed and formed is placed on the lower mold 13, and the heating rod 111 in the heating fixing block 11 is heated to heat the lower mold mounting plate 12, and then the heat is transferred to the lower mold 13, so that the automobile instrument panel bracket casting thereon is heated and softened; at the same time, the heating rod 331 in the upper heating block 33 is also heated to heat the upper mold mounting plate 34, and then the upper mold 35 is also heated and heated, and then the upper mold 35 is pushed by the push rod of the molding cylinder 31 to descend, so that the automobile instrument panel bracket casting is between the upper mold 35 and the lower mold 13 to form a molding casting.

[0058] Wherein, the front wall surface of the heating fixed block 11 and the front wall surface of the upper heating block 33 are both fixed with stoppers;

[0059] When it is necessary to replace the upper mold 35 and the lower mold 13, such as replacing the lower mold 13, first turn the top surface of the flip support plate 21 upward, remove the bolts connecting the lower mold mounting plate 12 and the heating fixing plate 11, and then push the lower mold mounting plate 12 (which is connected to the lower mold 13 and pushed out at the same time), push it backward to the top surface of the flip support plate 21 (the front limit block 2 and the rear limit block 3 are pulled out from the flip support plate 21 at this time), and then use a crane to take it out from the lower mold mounting plate 12 and the lower mold 13 thereon;

[0060] When removing the upper mold 35, the height position of the horizontal lifting fixed plate 23 is adjusted by operating the lifting servo motor 54 until the top surface of the flip support plate 21 is basically flush with the bottom surface of the upper mold 35 (at this time, the lifting servo motor 54 is manually controlled to operate, and it is not affected by the induction end of the position-limiting proximity switch 60). Then, the bolts connecting the upper mold mounting plate 34 to the bottom surface of the upper heating block 33 are removed, and then the upper mold mounting plate 34 is pushed backward to the top surface of the flip support plate 21 to achieve disassembly, which is very convenient.

[0061] When installing the lower die 13, first use a crane to place the lower die mounting plate 12 with the lower die 13 mounted on the top surface of the flip support plate 21, and transfer the four side adjustment bolts 216 so that the self-lubricating wear-resistant layer fixed on the inner wall of the side adjustment guide block 214 is in close contact with the left or right wall of the lower die mounting plate 12.

At this time, the left and right walls of the lower die mounting plate 12 are aligned with the straight lines extending forward and backward of the corresponding positioning mark 9.

[0062] At this time, the sensing end of the limit proximity switch 60 senses the annular raised circle of the first adjusting screw sleeve 62, and the top surface of the flip support plate 21 and the bottom surface of the dovetail groove 112 formed on the top surface of the heating fixed block 11 are on the same horizontal plane (it can have an error of about 1mm to 2mm. When the difference between the two is large, it is necessary to manually control the lifting servo motor 54 to run, change the height position of the top surface of the flip support plate 21, and ensure the accuracy of the position). Then, manually operate the control button of the control host to make the moving motor 412 run, so that the horizontal support plate 42 moves forward, and the horizontal push plate 46 moves forward, and its front end is against the lower mold 13 and the lower mold.
