Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, and particularly relates to an automatic mold opening device for a precision stamping die for hardware processing. Background Art

[0002] A stamping die is a metal processing method that applies pressure to a material using a die installed on a press at room temperature to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] During the mold opening and closing process of a stamping die, when the punch exits the die, due to the cooling and shrinkage of the hardware, it will get stuck outside the punch and cannot be unloaded. Usually, the method of manually prying the mold is used to unload the material, but this is very easy to damage the punch, and the labor intensity is high and the work efficiency is low. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic mold opening device for a precision stamping die for hardware processing, and solve the problems that during the mold opening and closing process of a stamping die, when the punch exits the die, due to the cooling and shrinkage of the hardware, it will get stuck outside the punch and cannot be unloaded. Usually, the method of manually prying the mold is used to unload the material, but this is very easy to damage the punch, and the labor intensity is high and the work efficiency is low.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an automatic mold opening device for a precision stamping die for hardware processing, including a base, a punching head and a material picking component. One side of the upper surface of the base is fixedly connected with a support frame, the top end of the support frame is fixedly connected with a mounting frame, the punching head is arranged in the mounting frame and is slidably matched with it. One side of the bottom surface of the mounting frame is fixedly connected with a fixing plate, the fixing plate is in an "L" shape, one end of the fixing plate is fixedly connected with a mold opening ring, the bottom end of the punching head is fixedly connected with a punching die rod, the punching die rod is arranged in the mold opening ring and is slidably matched with it. The upper surface of the base is fixedly connected with a punching die base, and the punching die base is arranged directly below the punching die rod.

[0007] The material picking component includes a material picking box. Both side surfaces of the material picking box are provided with chutes. One side surface of the material picking box is hinged with a connecting plate. The connecting plate is arranged on one side of the chute. One end of the connecting plate is hinged with a linkage plate. One side of the upper surface of the base is fixedly connected with a fixed block, and one end of the linkage plate is hinged with the fixed block.

[0008] Another side of the material picking box is hinged with a connecting plate. The connecting plate is arranged on one side of the sliding groove. One end of the connecting plate is hinged with a matching plate. One side of the bottom surface of the stamping head is fixedly connected with a connecting block. One end of the matching plate is hinged with the connecting block. A sliding rod is fixedly connected between the matching plate and the linkage plate. The sliding rod is arranged in the sliding groove and is slidably matched with it.

[0009] The material picking box is in the shape of a right triangle and is arranged between the stamping die rod and the die holder.

[0010] The utility model has the following beneficial effects:

[0011] By arranging a stamping head, a mold opening ring and a material picking assembly, the utility model can realize that after the die stamping work is completed, the stamping head drives the stamping die rod to move upward. At the same time, when the stamping head moves upward, the connecting block is used to drive the matching plate to swing, and then drive the connecting plate to swing, and make the sliding rod slide in the sliding groove, so that the linkage plate and the connecting plate cooperate to swing, thereby driving the material picking box to move under the stamping die rod. At this time, the stamping die rod slides upward in the mold opening ring. With the cooperation of the mold opening ring, the hardware material stuck on the stamping die rod is removed, and the removed material falls into the material picking box and slides out along the material picking box, which is convenient for the staff to collect; with the cooperation of the sliding groove, the linkage plate, the connecting plate, the sliding rod, the matching plate and the connecting plate, when the stamping head moves downward for stamping, it drives the material picking box to move to one side of the stamping head, and thus does not affect the normal operation of the stamping work.

[0012] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Description of the Drawings
