[0004] Although the existing technical solutions mentioned above can improve processing efficiency by setting up a lifting mechanism to facilitate the quick removal of the guard plate, the existing integrated automotive guard plates lack effective positioning during the stamping process, making the workpiece prone to displacement under impact force. In addition, the mold is tightly attached to the fixed mold after stamping, making demolding troublesome.

[0005] In view of this, we propose a processing device for an integrated protective plate. Utility Model Content

The device achieves the technical effect of positioning and demolding.

[0008] 2. Technical Solution

[0009] This application provides a processing device for an integrated protective plate, including a moving mold and a fixed mold. The fixed mold includes a mold table, a vertical plate, and a base plate. Guide pillars are provided at four ends on the top of the fixed mold. The guide pillars are slidably inserted into the four ends of the moving mold. Ejection assemblies are provided on both sides of the moving mold extending downward into the interior of the fixed mold. The ejection assembly includes hollow rods. Two hollow rods are respectively provided on the outer walls of both sides of the moving mold, and connecting rods are slidably inserted below the hollow rods. The bottom ends of the two connecting rods are connected to ejection plates, and the ejection plates are arranged parallel between the mold table and the base plate. An ejection rod is provided at the top of the ejection plate, and the ejection rod is slidably inserted into the interior of the mold table.

[0010] Preferably, the mold platform has upright plates at the front and rear positions of its bottom end, and the bottom end of the upright plates is connected to a base plate.

[0016] 3. Beneficial effects

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] (1) This application is equipped with an ejection assembly. After the stamping is completed, the moving mold slides down. First, the connecting rod and the hollow rod slide to the maximum critical value. At this time, the moving mold and the mold table maintain a certain distance. The ejection rod has not yet moved. The moving mold continues to rise. At this time, the connecting rod will pull the ejection plate to move upward, so that the spring inside the hidden groove is stretched, and the ejection plate is moved to the top. This drives the ejection rod to eject the mold table, so that the workpiece can be lifted up smoothly. This makes the guard plate part form a movable space, which is convenient for the robot to clamp and stack it for unloading.

[0019] (2) This application provides a positioning rod and a guard plate. By aligning the reserved hole on the guard plate with the two positioning rods, the guard plate can be effectively prevented from shifting during the extrusion process, thus achieving a center positioning effect. The positioning rod is inserted into the slot to ensure that the moving die and the die table can fit together completely during the stamping process. Attached Figure Description

Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Please see Figure 1-4 An embodiment of this utility model provides: a processing device for an integrated protective plate, including a moving mold 110 and a fixed mold 120. The fixed mold 120 includes a mold table 121, a vertical plate 122 and a base plate 123. Guide posts 130 are provided at four ends on the top of the fixed mold 120. The guide posts 130 are slidably inserted into the four ends of the moving mold 110. Ejection components 200 are provided on both sides of the moving mold 110 extending downward into the interior of the fixed mold 120.

[0028] The ejection assembly 200 includes hollow rods 210. Two hollow rods 210 are respectively disposed on the outer walls of the two sides of the moving mold 110. A connecting rod 212 is slidably inserted below the hollow rods 210. The bottom ends of the two connecting rods 212 are connected to an ejection plate 213. The ejection plate 213 is disposed parallel between the mold table 121 and the base plate 123. An ejection rod 214 is disposed at the top of the ejection plate 213. The ejection rod 214 is slidably inserted into the mold table 121. A limiting block 211 is disposed at the top of the connecting rod 212. The limiting block 211 moves in the slides on both sides of the hollow rod 210. Hidden grooves 215 are evenly opened inside the base plate 123. Spring members 216 are disposed inside each hidden groove 215. The top ends of the spring members 216 are connected to the bottom ends of the ejection plate 213. When the bottom ends of the ejection plate 213 are attached to the top ends of the base plate 123, the top ends of the ejection rods 214 are kept horizontal with the top ends of the mold table 121. Driven by the hydraulic rod, the moving die 110 slides upward along the guide post 130 to press, cooperating with the die table 121 to extrude the guard plate 140. At this time, the connecting rod 212 slides to one end of the hollow rod 210, and the connecting rod 212 is completely housed inside the hollow rod 210. After the pressing is completed, the moving die 110 slides downward. First, the connecting rod 212 and the hollow rod 210 slide apart to the maximum critical value. At this time, the moving die 110 and the die table 121 maintain a certain distance, and the ejector rod 214 has not yet moved. The moving die 110 continues to rise, and at this time the connecting rod... 212 will pull the ejector plate 213 upward, causing the spring 216 inside the hidden groove 215 to stretch, moving the ejector plate 213 to the uppermost position, driving the ejector rod 214 to eject the mold table 121, so that the workpiece can be smoothly ejected, and the guard plate 140 can form a movable space, which is convenient for the robot to clamp and stack it for unloading. When the moving mold 110 descends, it will first drive the ejector plate 213 and ejector rod 214 to reset, and then the connecting rod 212 will retract inside the hollow rod 210. Through the above reciprocating motion, the workpiece is stably ejected after stamping.

[0029] Furthermore, a vertical plate 122 is provided at the front and rear positions of the bottom end of the mold table 121, and a base plate 123 is connected to the bottom end of the vertical plate 122. A slot 111 is provided inside the moving mold 110, and a positioning rod 124 is provided at the top of the mold table 121 corresponding to the slot 111. By aligning the reserved hole 141 on the guard plate 140 with the two positioning rods 124, the guard plate 140 can be effectively prevented from shifting during the extrusion process, thus achieving a center positioning effect. The positioning rod 124 is inserted into the slot 111 to ensure that the moving mold 110 and the mold table 121 can be fully engaged during stamping.

[0030] In summary, when using the integrated protective plate processing device disclosed in this application, the moving mold 110 slides upward along the guide post 130 under the push of the hydraulic rod, and presses against the protective plate 140 in conjunction with the mold table 121. At this time, the connecting rod 212 slides to one end of the hollow rod 210, and the connecting rod 212 is completely housed inside the hollow rod 210. After the stamping is completed, the moving mold 110 slides downward. First, the connecting rod 212 and the hollow rod 210 slide apart to the maximum critical value. At this time, the moving mold 110 and the mold table 121 maintain a certain distance, and the ejector rod 214 has not yet moved. As the moving mold 110 continues to rise, the connecting rod 212 pulls the ejector plate 213 upward, causing the spring 216 inside the hidden groove 215 to stretch, moving the ejector plate 213 to its uppermost position. This drives the ejector rod 214 to eject the mold table 121, allowing the workpiece to be smoothly ejected. This creates a movable space between the upper and lower parts of the guard plate 140, facilitating clamping, stacking, and unloading by a robotic arm. When the moving mold 110 descends, it first resets the ejector plate 213 and ejector rod 214. Then, the connecting rod 212 retracts inside the hollow rod 210. Through this reciprocating motion, the workpiece is stably ejected after stamping. Aligning the pre-drilled hole 141 on the guard plate 140 with the two positioning rods 124 effectively prevents the guard plate 140 from shifting during the extrusion process, providing a centering positioning effect. The positioning rods 124 are inserted into the slots 111, ensuring that the moving mold 110 and the mold table 121 can fully engage during stamping.
