Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a mold for producing engine hood support brackets. Background Technology

[0002] A hood support bracket, typically used to support and adjust a car's hood, adjusts the gap between the hood and the front of the vehicle. It usually consists of a support rod and mounting sleeves at its ends. Hood support brackets are often manufactured using stamping dies. In the actual stamping process, the movement of the two dies relies solely on the guidance of guide pillars to achieve proper fit. After a period of use, the guide pillars wear down, leading to poor fit between the dies and affecting the stamping quality of the support bracket. Furthermore, the misalignment of the die components is difficult to observe, increasing the number of defective products and raising production costs. Therefore, we propose a die for producing hood support brackets. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a mold for producing engine hood support brackets. This effectively solves the problem that in the actual stamping production process, the movement trajectory of two molds in existing stamping dies relies solely on the guidance of guide columns to achieve the fit between the two molds. After a period of use, the guide columns will wear out, resulting in poor fit between the molds, affecting the stamping quality of the support bracket. Furthermore, the misalignment of the mold parts is not easily observed, leading to an increase in the number of defective products and higher production costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A mold for producing an engine hood support frame includes a support base, a lower mold fixedly mounted on the top surface of the support base, an upper mold movably connected to the upper side of the support base, and the upper side of the upper mold is adjusted in the vertical direction by a drive shaft. It also includes a mounting groove in the middle of the top surface of the upper mold, and a plurality of overlapping grooves are provided in a ring at equal intervals on the outer circumference of the mounting groove. It also includes a rotating plate movably connected in the mounting groove, and a disc is fixedly mounted on the lower end of the drive shaft. The lower outer wall of the disc overlaps with the outer wall of the rotating plate.

[0005] Preferably, guide frames are fixedly installed on both sides of the support base, and the outer wall of the upper mold slides in conjunction with the inner wall of the guide frames.

[0006] Preferably, a fixing ring is fixedly installed on the top surface of the upper mold, the fixing ring is slidably engaged with the outer wall of the drive shaft, and the outer end of the rotating plate extends to the inner position of the overlapping groove, and a contact piece is provided on the upper inner wall of the overlapping groove. When the outer wall of the rotating plate contacts the contact piece, the warning light fixedly installed on the top surface of the support seat is activated.

[0007] Preferably, it further includes a guide rod fixedly installed at the lower end of the guide frame, the guide rod slidingly engaging with the upper mold, and the lower end of the guide rod having multiple equally spaced grooves in a ring shape, with multiple metal plates slidably connected within the grooves.

[0008] Preferably, the metal plate is arranged in an arc shape, and the lower outer wall of the metal plate slides in contact with the inner wall of the groove located in the middle of the mounting plate.

[0009] Preferably, a mounting plate is fixedly installed at the lower end of the guide frame, and multiple pressure sensors are arranged in a ring at equal intervals on the outer circumference of the groove. The pressure sensors are used to detect the force exerted by the metal plate on the pressure sensors.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model, through the setting of a guide rod and multiple metal plates movably connected to its lower side, can detect whether the corresponding mold has shifted during stamping by judging multiple pressure sensors set in the groove, and adjust the state of the mold in time to ensure the stamping accuracy of the support frame.

[0017] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0018] See attached document Figure 1-4 As shown, a mold for producing an engine hood support frame includes a support base 100. A lower mold 110 is fixedly installed on the top surface of the support base 100. An upper mold 200 is movably connected to the upper side of the support base 100, and the upper side of the upper mold 200 is adjusted in the vertical direction by a drive shaft 300. Specifically, in this application, during the actual stamping process, the upper mold 200 can be adjusted relative to the support base 100, and the metal part to be stamped is placed on the upper side of the lower mold 110. It should be noted that a cutting blade is fixedly installed on the bottom surface of the upper mold 200. When the upper mold 200 moves downward to cut the metal part, it can effectively cut and process the metal part.

[0019] Furthermore, this application also includes a mounting groove 201 formed in the middle of the top surface of the upper mold 200. Multiple overlapping grooves 202 are evenly spaced in a ring on the outer circumference of the mounting groove 201. It also includes a rotating plate 220 movably connected within the mounting groove 201. A disc 310 is fixedly mounted on the lower end of the drive shaft 300, and the lower outer wall of the disc 310 overlaps with the outer wall of the rotating plate 220. Specifically, the upper mold 200 needs to reciprocate vertically under the action of an external drive mechanism. In this application, to ensure that the upper mold 200 moves vertically downwards, the drive shaft 300 is fixedly connected to the output shaft of an external hydraulic cylinder or linear motor. This fixed connection refers to a relatively fixed position in the vertical direction.

[0020] Specifically, in this application, the connection between the drive shaft 300 and the upper mold 200 is maintained in a rotatable connection in the horizontal direction. Correspondingly, in the vertical direction, a fixing ring 210 is fixedly installed on the top surface of the upper mold 200. The fixing ring 210 slides against the outer wall of the drive shaft 300. This means that when the drive shaft 300 is adjusted in the vertical direction, the drive shaft 300 will adjust its position relative to the fixing ring 210. In the actual stamping process, considering the possible deviation of the output trajectory of the hydraulic cylinder or other drive mechanism, in this application, a disc 310 is fixedly installed at the lower end of the drive shaft 300. The disc 310 is located inside the mounting groove 201. In the actual stamping process, the lower outer wall of the disc 310 will contact the outer walls of multiple rotating plates 220. Through the multiple rotating plates 220 as the transmission medium, the upper mold 200 is driven to move downward, thereby realizing the downward movement of the upper mold 200 and ultimately achieving stamping.

[0021] In one implementation, guide frames 120 are fixedly installed on both sides of the support base 100. The outer wall of the upper mold 200 slides in conjunction with the inner wall of the guide frame 120. When the upper mold 200 moves downward, the guide frame 120 limits the movement trajectory of the upper mold 200. The outer end of the rotating plate 220 extends to the inner position of the overlapping groove 202, and a contact piece is provided on the upper inner wall of the overlapping groove 202. When the outer wall of the rotating plate 220 contacts the contact piece, the warning light fixedly installed on the top surface of the support base 100 is activated. In the actual stamping process, the corresponding disc 310 will press the rotating plate 220 installed in the mounting groove 201 and drive the rotating plate 220 to rotate in the mounting groove 201. Since the rotating plate 220 is bent, when the disc 310 rotates... After an external force is applied to plate 220, the end of the rotating plate 220 will rotate from bottom to top within the overlapping groove 202. At this time, the outer end of the rotating plate 220 will contact the contact piece set on the inner wall of the overlapping groove 202. The contact piece mentioned above is a type of trigger switch. When the upper end of the rotating plate 220 contacts the outer wall of the contact piece, the warning light on the bottom surface of the corresponding support 100 will be in an energized state. The warning light will only be turned on when all contacts are in contact. By judging the operating state of the warning light, it can be determined whether the force applied by the drive shaft 300 to the upper mold 200 is vertically downward. If the warning light does not light up during a stamping, it is understood that the upper mold 200 is not in a horizontal state. At this time, the state of the upper mold 200 needs to be adjusted to ensure the stamping quality.

[0022] Furthermore, it also includes a guide rod 400 fixedly installed at the lower end of the guide frame 120. The guide rod 400 is slidably engaged with the upper mold 200, and the lower end of the guide rod 400 has multiple equally spaced annular grooves 401, in which multiple metal plates 410 are slidably connected. Specifically, in the actual stamping process, fixed plates are fixedly installed at both ends of the upper mold 200. During stamping, the corresponding fixed plates slide downward within the guide frame 120. The corresponding fixed plates have circular holes, and the guide rod 400 slides within the circular holes. This is also a type of guiding method. Furthermore, before stamping, the outer wall of the fixed plate will contact the multiple metal plates 410 slidably connected to the lower outer wall of the guide rod 400.

[0023] Specifically, the metal plate 410 has an arc-shaped structure, and the lower outer wall of the metal plate 410 slides in contact with the inner wall of the groove 131 located in the middle of the mounting plate 130. The mounting plate 130 is fixedly mounted on the lower end of the guide frame 120, and multiple pressure sensors 132 are arranged in a ring at equal intervals on the outer circumference of the groove 131. The pressure sensors 132 are used to detect the force exerted by the metal plate 410 on the pressure sensors 132. When the upper mold 200 moves down to a position close to the lower mold 110, the outer wall of the corresponding fixed plate will contact the upper outer wall of the multiple metal plates 410. As the stamping continues, the metal plates 410 that are movably connected in the slide groove 401 will slide downward in the slide groove 401, and the bottom end of the metal plate 410 will gradually slide along the inner wall of the groove 131 to the position of the corresponding pressure sensor 132. During the stamping, the lower outer wall of the corresponding metal plate 410 will be subjected to external force on the outer wall of the pressure sensor 132. By collecting the pressure data of the multiple metal plates 410 through the multiple pressure sensors 132 arranged in a ring structure, it is possible to determine whether the upper mold 200 tilts or shifts during the stamping. By collecting the pressure data and judging the corresponding pressure data, it is possible to determine whether the fit between the upper mold 200 and the lower mold 110 is accurate during the actual stamping process. In this way, the position of the mold can be adjusted before stamping to ensure the actual stamping quality.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
