Description

Technical Field

[0001] This utility model relates to the field of mold processing, and in particular to a mold for processing a front wheel arch connecting plate that is easy to demold. Background Technology

[0002] The front wheel arch connector plate is an important component in the automotive body structure. It is typically used in conjunction with the front wheel arch to enhance the connection strength between the front wheel arch and other parts of the vehicle body. The front wheel arch connector plate offers the following advantages: it securely connects the front wheel arch to the vehicle body, improving the overall structural strength and rigidity; and during vehicle operation, the connector plate disperses impacts and stresses on the front wheel arch, protecting the vehicle body structure from damage.

[0003] In the processing of the front wheel arch connecting plate, stamping is typically used, a process that employs stamping dies. Existing stamping dies, after stamping, use an ejector rod to eject the connecting plate quickly. However, existing stamping dies only have one ejector rod, which can only eject the middle portion of the product, easily leading to ejection jamming. Furthermore, the ejector rod is simply used in conjunction with a spring, and the spring's compression cannot be adjusted, resulting in a fixed ejection force and poor adaptability. Utility Model Content

[0004] The main purpose of this utility model is to provide a mold for processing the front wheel arch connecting plate that is easy to demold, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a mold for processing a front wheel arch connecting plate that facilitates demolding includes a fixed base 1 and a movable base 4. A support base 2 is provided on the fixed base 1, and a lower mold 3 is mounted on the support base 2. An upper mold 5 is connected to the movable base 4. The lower mold 3 has a stamping cavity 6, and the upper mold 5 has a stamping head 7. Grooves 8 are provided on both the fixed base 1 and the support base 2, and an ejector structure 9 is provided in the groove 8. The upper end of the ejector structure 9 is located inside the stamping cavity 6. A guide post 10 is fixedly installed on the fixed base 1, and a guide sleeve 11 is installed on the movable base 4, with the guide sleeve 11 fitted onto the guide post 10. A lifting connecting frame 12 is fixedly installed on the upper end of the movable base 4, and the stamping head 7 is located directly above the stamping cavity 6.

[0019] When processing the front wheel arch connecting plate using a mold, the fixed seat 1 is fixedly installed, while the movable seat 4 is installed on the drive mechanism. The sheet metal is placed on the lower mold 3. After the drive mechanism is started, it lowers the movable seat 4 via the lifting connecting frame 12. The movable seat 4 then lowers the upper mold 5 and the stamping head 7 to stamp the sheet metal. The stamping head 7, in conjunction with the stamping cavity 6 on the lower mold 3, completes the stamping of the sheet metal. During this process, the guide sleeve 11 moves along the guide post 10 to ensure the accuracy of the mold movement. During the stamping process, after the sheet metal bends into the stamping cavity 6, the ejector structure 9 lowers to make way, without affecting the normal operation of the stamping work. After stamping is completed, the drive mechanism raises the movable seat 4 and the upper mold 5, and the stamping head 7 leaves the sheet metal. At the same time, under the action of the ejector structure 9, the sheet metal is ejected from the stamping cavity 6, thus achieving a rapid demolding effect and making the mold demolding work convenient and quick.

[0020] According to the above implementation scheme, the ejection structure 9 includes a mounting plate 901, a mounting base 902, a mounting bolt 903, and an ejection assembly 904. The mounting plate 901 is fixedly connected to the mounting base 902, and the mounting plate 901 is provided with a threaded hole. The mounting bolt 903 passes through the mounting plate 901 and the mounting base 902, and the end of the mounting bolt 903 is connected to the support base 2 and the lower die 3. The ejection assembly 904 is installed in the threaded hole on the mounting plate 901, and the upper end of the ejection assembly 904 passes through the lower die 3 and is located in the stamping cavity 6. The ejection assembly 904 includes a threaded sleeve 9041, an adjusting plate 9042, a movable rod 9043, a limiting plate 9044, a spring 9045, a threaded connector 9046, and a rubber head 9047. The threaded sleeve 9041 is fixedly connected to the adjusting plate 9042 and is connected in a threaded hole. The threaded sleeve 9041 and the adjusting plate 9042 are provided with through holes. The movable rod 9043 is fixedly connected to the limiting plate 9044 and is located in the through hole. The spring 9045 is sleeved on the movable rod 9043 and is located between the threaded sleeve 9041 and the limiting plate 9044. The threaded connector 9046 is fixed to the upper end of the movable rod 9043 and is threadedly connected to the rubber head 9047.

[0021] During stamping, after the sheet metal enters the stamping cavity 6, it exerts a force on the rubber head 9047 in the ejector assembly 904. The rubber head 9047 then lowers the movable rod 9043, and the limiting plate 9044 lowers to compress the spring 9045. After stamping is completed, the stamping head 7 leaves the sheet metal. Under the action of the spring 9045, the limiting plate 9044 raises the movable rod 9043, and the movable rod 9043 applies a force to the sheet metal through the rubber head 9047, so that the sheet metal can be quickly demolded. When needed, the relative position of the threaded sleeve 9041 can be adjusted by adjusting the adjusting plate 9042, thereby changing the initial compression degree of the spring 9045 and adjusting the ejection force. If the rubber head 9047 is worn out due to long-term use, the rubber head 9047 can be removed from the threaded joint 9046 for replacement. The operation is very convenient. Alternatively, the mounting bolt 903 can be removed to disassemble and replace the mounting plate 901, mounting base 902 and ejection assembly 904. The structure is simple and the operation is very convenient.

[0022] It should be noted that the mounting plate 901 and mounting base 902 are fixed by mounting bolts 903 through the ejection structure 9, which facilitates quick installation and disassembly of the entire ejection structure 9 and provides high operational flexibility. Multiple ejection components 904 are set on the mounting plate 901 to eject the connecting plate at multiple points, which increases the ejection effect. The ejection component 904 is equipped with a threaded sleeve 9041, which can be adjusted in position. When used in conjunction with the limiting plate 9044 on the movable rod 9043, the compression degree of the spring 9045 can be adjusted, thereby changing the initial force of the spring 9045 and thus changing the ejection force. This provides high adaptability. A rubber head 9047 is threadedly connected to the upper end of the movable rod 9043, which can provide a buffering effect during the ejection process, ensuring the integrity of the movable rod 9043 and allowing for quick replacement after wear and tear from long-term use.

[0023] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
