Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically a molding die for easy material cutting. Background Technology

[0002] Pallets and other workpieces require stamping during production. This step is crucial for ensuring the structural stability and practical performance of the workpiece. By using a press and a special mold, external force is applied to the raw material, causing it to undergo plastic deformation or separation, thereby obtaining stamped parts that meet the preset shape and size requirements. This is a commonly used forming technology in the industrial manufacturing field.

[0003] For example, the patent with authorization announcement number CN222268421U describes a stamping die that facilitates material unloading. After stamping, the upper die is moved upward and reset by a hydraulic cylinder. After the upper die separates from the stamped part, the fixing block is moved upward and reset by the spring force. The fixing block pushes the push plate upward through the connecting rod. The push plate pushes the stamped part upward, so that the push plate moves upward and resets. The stamped part is misaligned with the lower die, making it easy to remove the stamped part.

[0004] The existing technology has the following problems: Existing technology uses a spring to drive the movement of a fixed block, connecting rod, and push plate, causing the stamped part to be misaligned with the lower die for removal. However, after the stamping operation is completed, the stamped part is often tightly attached to the surface of the lower die. Moreover, the elastic characteristics of the spring not only make it difficult to ensure uniform force application, but also easily cause excessive local force to scratch the surface of the stamped part. Furthermore, with the increase of use, fatigue attenuation will occur, resulting in unstable power. This will lead to poor removal of the stamped part or slight deformation, affecting processing efficiency and product quality.

[0005] Based on this, a mold for pressing products that facilitates material feeding is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a mold for easy material feeding of molded products, so as to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A mold for easy material feeding includes an adjusting box, a plurality of support columns installed at the bottom of the adjusting box, the support columns being fixedly connected to a base, a stamping table installed on the surface of the adjusting box, two lower molds provided on the stamping table, an upper mold provided above the lower molds, a fixing frame provided on the side of the base, a hydraulic cylinder installed on the fixing frame, the hydraulic cylinder driving the upper mold to move, a feeding mechanism installed on the base, the feeding mechanism including a telescopic cylinder, the telescopic cylinder being installed on the surface of the base, the telescopic cylinder driving a transmission rod to move, the transmission rod being slidably connected to the adjusting box in the middle, the transmission rod passing through the stamping table, and the end of the transmission rod being fixedly connected to a top platform.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the transmission rod is fixedly connected to a transmission seat, and a connecting rod is rotatably connected to each end of the transmission seat, and the connecting rod is rotatably connected to a rotating rod.

[0009] In one alternative: the rotating rod is rotatably connected to the rotating shaft, and the rotating shaft is fixedly connected to the inner wall of the adjusting box.

[0010] In one alternative: a sector gear is fixedly connected to the end of the rotating rod.

[0011] In one alternative: the stamping platform has two sliding grooves, and a sliding block is slidably disposed in the sliding grooves.

[0012] In one alternative: one end of the sliding block is fixedly connected to the lower mold, and the other end of the sliding block is fixedly connected to the rack, which is adapted to the sector gear.

[0013] In one alternative: the lower mold is provided with a storage groove that is adapted to the top platform.

[0014] In one alternative: the surface of the sliding block is provided with a guide block, and the surface of the chute is provided with a material leakage groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a telescopic cylinder to drive the transmission rod, top platform, and transmission seat to move. The top platform lifts the workpiece molded in the lower mold upwards. At the same time, the transmission seat drives the connecting rods on both sides to move together. The connecting rods drive the rotating rod to rotate around the rotating shaft. The rotating rod drives the sector gear to swing, so that the sector gear meshes with the rack and drives the rack to drive the sliding block to slide along the slide groove. The sliding block then drives the lower mold to move synchronously. This linkage process makes the two lower molds automatically detach from the workpiece to both sides when the top platform lifts the workpiece, effectively avoiding scratching the workpiece surface and improving product quality.

[0016] 2. This utility model improves transmission stability by setting a guide block on the surface of the sliding block and opening a material leakage groove on the surface of the slide groove to prevent stamping debris from falling into the slide groove. Attached Figure Description
