Description

Technical Field

[0001] This utility model belongs to the field of automotive mold processing technology, specifically relating to an automotive mold edge pressing device. Background Technology

[0002] In the automotive manufacturing industry, the forming quality of body panels (such as doors, hoods, trunk lids, etc.) directly determines the appearance precision, aerodynamic performance, and structural stability of the car. Die pressing and stamping are the core processes in the processing of body panels. The core function of the die pressing device is to press and limit the edge of the workpiece during the stamping process to avoid defects such as wrinkling and cracking caused by uneven material flow. At the same time, it needs to cooperate in the ejection and unloading of the workpiece after stamping. Therefore, it is necessary to design an automotive die pressing device.

[0003] In the existing technology, the blanking operation of automotive molds and the ejection operation of stamped workpieces usually require two independent sets of equipment or two independent drive mechanisms to complete. Blanking relies on a special blanking component, while ejection requires an additional cylinder or hydraulic ejection mechanism. This not only results in a large overall size of the equipment and occupies a lot of production space, but also requires separate control of the operating rhythm of the two mechanisms, increasing the equipment purchase cost and subsequent maintenance cost. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed automotive mold pressing device in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An automotive mold pressing device includes a base assembly, the base assembly including a worktable, a top mounting assembly fixed on the top of the worktable, a stamping assembly that cooperates with the base assembly being slidably mounted at the middle position inside the top mounting assembly, and pressing ejection assemblies symmetrically slidably mounted on both sides inside the top mounting assembly, the two pressing ejection assemblies being fitted onto the outside of the base assembly and slidably engaged with its interior.

[0007] As a further optimization of this utility model, an installation platform is fixedly installed at the middle position of the top of the workbench, and a die mechanism is threadedly fixed to the top of the installation platform. An opening groove is provided at the middle position inside the workbench, which communicates with the installation platform and the die mechanism inside and outside. Limiting rollers are rotatably installed on both sides of the top of the workbench.

[0008] As a further optimization of this utility model, the top mounting assembly includes support rods fixedly installed on both sides of the workbench, and a fixing plate placed above the workbench is fixedly fixed on the top of the multiple support rods on the side close to each other, and a U-shaped fixing plate is fixedly installed at the middle position of the top of the fixing plate.

[0009] As a further optimization of this utility model, the stamping assembly includes a hydraulic cylinder fixedly installed at the top middle position inside the U-shaped fixed plate, and the output end of the hydraulic cylinder slides through into the interior of the fixed plate. The output end at the bottom of the hydraulic cylinder is threadedly fixedly installed with a punch mechanism placed above the worktable and cooperating with the die mechanism.

[0010] As a further optimization of this utility model, the pressing and ejecting assembly includes two electric push rods fixedly installed on the top sides of the U-shaped fixed plate, and the output ends of the bottom of the electric push rods slide through into the interior of the fixed plate. The output ends of the bottom of the two electric push rods are threadedly fixedly installed with mounting plates placed above the two limiting rollers. The bottom of the two mounting plates are rotatably installed with pressing rollers that cooperate with the limiting rollers.

[0011] As a further optimization of this utility model, both ends of the two mounting plates are fixedly installed with U-shaped limiting rods that fit around the outer sides of the workbench. A connecting rod is installed at the bottom of the two U-shaped limiting rods on the side closest to each other. A top plate extending into the opening groove is fixedly installed on the top of the connecting rod.

[0012] The beneficial effects of this utility model are as follows: This utility model integrates the pressing and ejection functions into the same component through the integrated design of the pressing and ejection assembly. On the one hand, the electric push rod drives the mounting plate to cooperate with the pressing roller and the limiting roller on the worktable to achieve precise pressing of the workpiece edge. On the other hand, the U-shaped limiting rods at both ends of the mounting plate are connected to the top plate through connecting rods. When the electric push rod drives the mounting plate to reset upward, the top plate can slide upward synchronously along the opening groove to directly eject the formed workpiece in the die mechanism. This design does not require additional independent ejection equipment, which greatly simplifies the overall structure, reduces the space occupied by the equipment, and reduces the comprehensive cost of equipment purchase, installation and subsequent maintenance.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an automotive mold pressing device includes a worktable 100, which is made of high-strength alloy steel to ensure sufficient load-bearing capacity. U-shaped support legs are fixedly installed on both sides of the bottom edge of the worktable 100 by threads. Anti-slip blocks are fixedly installed on the bottom of the two U-shaped support legs to improve the stability of the worktable 100 during later support placement. The material of the U-shaped support legs is the same as that of the worktable 100. At the middle position of the top of the worktable 100, a mounting platform 102 is fixedly installed by welding, which is perpendicular to the worktable 100. The top of the mounting platform 102 has evenly distributed threaded holes. The die mechanism 103 is threadedly fixed to the top of the mounting platform 102 by bolts engaging with the threaded holes. The cavity opening of the die mechanism 103 faces upwards and is used to place the automotive mold workpiece to be processed.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, in order to realize the subsequent workpiece ejection function, an open slot 104 that runs vertically through the middle position inside the worktable 100 is provided. The size of the open slot 104 is smaller than the internal channel of the mounting table 102 and the die mechanism 103. The open slot 104 is connected to the inside and outside of the mounting table 102 and the die mechanism 103 to form a channel for workpiece ejection. In addition, two limiting rollers 101 are rotatably installed on both sides of the top of the worktable 100 via a rotating shaft. The two limiting rollers 101 are symmetrically distributed on both sides of the mounting table 102. The axis of the limiting rollers 101 is set horizontally and is used to perform preliminary limiting and pressure plate work on the edge of the workpiece to be processed.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, to install the stamping assembly 3 and the pressing and ejecting assembly 2, a top mounting assembly 4 is provided above the base assembly 1. The top mounting assembly 4 includes four support rods 402, which are respectively fixed to both ends of the worktable 100 by bolts. That is, each corner of the worktable 100 corresponds to one support rod 402. The support rods 402 extend vertically upward. On the top of the side where multiple support rods 402 are close together, a horizontally set fixing plate 401 is fixed together by welding. The size of the fixing plate 401 is adapted to the top size of the worktable 100, and the fixing plate 401 is placed parallel to the top of the worktable 100 to form a stable top mounting platform. At the middle position of the top of the fixing plate 401, a U-shaped fixing plate 400 is fixedly installed by welding. The opening of the U-shaped fixing plate 400 faces downward, and its internal space is used to install the drive component.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the stamping assembly 3 is used to stamp and form the workpiece in the die mechanism 103. It includes a hydraulic cylinder 300 and a punch mechanism 301. The hydraulic cylinder 300 is fixedly installed in the middle position of the top of the U-shaped fixed plate 400 by bolts. The output end of the hydraulic cylinder 300 is set downward and passes through a pre-set through hole on the fixed plate 401. The size of the through hole is slightly larger than the diameter of the output end of the hydraulic cylinder 300, so that the output end of the hydraulic cylinder 300 can slide along the through hole axially to the bottom of the fixed plate 401.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a punch mechanism 301 is fixedly installed at the output end of the bottom of the hydraulic cylinder 300 by means of a threaded connection. The punch mechanism 301 is placed above the worktable 100, and the shape of the punch mechanism 301 is adapted to the cavity of the die mechanism 103. When the hydraulic cylinder 300 drives the output end to extend downward, the punch mechanism 301 can be accurately embedded in the cavity of the die mechanism 103 to realize the stamping and forming operation of the workpiece. Limiting guide rods are fixedly installed at the four corners of the top of the punch mechanism 301 by threads. The four limiting guide rods slide through the preset limiting guide holes on the fixed plate 401, which facilitates the improvement of the stability of the sliding displacement of the punch mechanism 301 in the later stage.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, two sets of blank holder ejection assemblies 2 are symmetrically arranged, respectively installed on both sides of the top of the top mounting assembly 4, for blank holder operation and ejection operation after stamping. Each set of blank holder ejection assembly 2 includes an electric push rod 200, a mounting plate 201, a blank holder roller 202, a U-shaped limiting rod 203, a connecting rod 204, and a top plate 205. Specifically, the two electric push rods 200 are respectively fixedly installed on both sides of the top of the U-shaped fixing plate 400 by bolts, and the two electric push rods 200 are symmetrically distributed. On both sides of the hydraulic cylinder 300, the output ends of the electric push rods 200 are set downwards, and their output ends slide through into the pre-set guide holes inside the fixed plate 401. The guide holes play a guiding and limiting role for the output ends of the electric push rods 200. At the output ends of the bottom of the two electric push rods 200, a horizontally set mounting plate 201 is fixedly installed by means of threaded connection. The mounting plate 201 is placed directly above the two limiting rollers 101, and the length direction of the mounting plate 201 is consistent with the axial direction of the limiting rollers 101.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, at the bottom of the two mounting plates 201, a pressing roller 202 is rotatably mounted via a rotating shaft. The axis of the pressing roller 202 is parallel to the axis of the limiting roller 101, and the position of the pressing roller 202 corresponds to the position of the limiting roller 101. When the electric push rod 200 drives the mounting plate 201 to move downward, the pressing roller 202 can cooperate with the limiting roller 101 to clamp the edge of the workpiece to be processed, thereby realizing the pressing operation.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, to ensure the stability of the mounting plate 201 during vertical movement, U-shaped limiting rods 203 are fixedly installed at both ends of the two mounting plates 201 by welding. The openings of the U-shaped limiting rods 203 face upwards, and the U-shaped limiting rods 203 fit around the two sides of the worktable 100, that is, the two sides of the worktable 100 are respectively embedded in the openings of the U-shaped limiting rods 203. This allows the U-shaped limiting rods 203 to slide along the sides of the worktable 100 when the mounting plate 201 moves up and down, thus playing a guiding and limiting role. At the bottom of the side where the two U-shaped limiting rods 203 are close to each other, a... A horizontally arranged connecting rod 204 is installed by welding. The length direction of the connecting rod 204 is consistent with the width direction of the worktable 100. A top plate 205 is fixedly installed on the top of the connecting rod 204 by welding. The size of the top plate 205 is adapted to the size of the opening slot 104 on the worktable 100, and the top plate 205 extends vertically upward into the interior of the opening slot 104. When the U-shaped limiting rod 203 moves upward with the mounting plate 201, the top plate 205 can slide upward along the opening slot 104 to eject the workpiece stamped in the die mechanism 103.

[0028] It should be noted that, in use, this automotive mold pressing device first places the automotive mold workpiece to be processed into the cavity of the die mechanism 103, while simultaneously placing the edge of the workpiece on the limiting rollers 101 on both sides of the worktable 100. Then, the electric push rod 200 is activated, driving the mounting plate 201 downwards, which in turn drives the pressing roller 202 downwards synchronously until the pressing roller 202 engages with the limiting rollers 101 to clamp the edge of the workpiece, completing the pressing and positioning. Subsequently, the hydraulic cylinder 300 is activated. The hydraulic cylinder 300 drives the punch mechanism 301 to move downward. The punch mechanism 301 is embedded in the die mechanism 103 to stamp the workpiece. After the stamping is completed, the hydraulic cylinder 300 drives the punch mechanism 301 to reset upward. At the same time, the electric push rod 200 drives the mounting plate 201 to move upward, which drives the U-shaped limit rod 203 and the connecting rod 204 to move upward synchronously. This causes the top plate 205 to slide upward along the opening groove 104, ejecting the formed workpiece in the die mechanism 103 and completing the entire processing flow.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
