Description

Technical Field

[0001] The utility model belongs to the technical field of mold structure design, and particularly relates to a quick demoulding mold structure. Background Art

[0002] Molds are essential tools used in industrial production to shape or process products. They primarily achieve the desired shape by altering the physical state of the material being molded. Specifically, molds apply external force to plastically deform or separate the blank, thereby creating a workpiece of the desired shape and size. Molds have a wide range of applications, encompassing virtually all industries requiring molding and processing, such as automotive, electronics, home appliances, healthcare, aviation, and aerospace. In industrial production, the use of molds can significantly improve production efficiency, reduce costs, and ensure product quality and consistency.

[0003] Chinese utility model patent CN220992507U discloses a mold structure capable of rapid demolding, comprising a supporting base; a guide slot is provided inside the top surface of the supporting base; and further comprising: an upper mold body is slidably provided above the supporting base, lifting threaded rods are symmetrically provided at the inner center positions of the supporting side plates, and limiting slide rods are fixedly provided on the front and rear sides of the left and right supporting side plates; wherein, the front and rear sides of the top of the lower mold body slide through and connect to the bottom end of the pressure cross plate, and the front and rear pressure cross plates and the lower mold body are connected to each other by reset springs. This mold structure capable of rapid demolding squeezes the material and the inner wall of the lower mold body apart by sliding the demolding guide plate and the demolding lifting plate provided inside the supporting base, and is lifted to the bottom surface of the workpiece by the push plate provided inside the lower mold body to eject it and complete demolding.

[0004] However, existing mold structures are mostly demolded manually. Manual demolding requires operators to manually remove the product from the mold, a time-consuming and labor-intensive process. Especially in large-scale production, manual demolding efficiency falls far short of production needs. Furthermore, during manual demolding, factors such as operator skill level and fatigue can lead to uneven demolding force, affecting product quality consistency. Furthermore, complex mold structures can pose safety risks during manual demolding. Therefore, resolving these technical issues is a pressing challenge in the industry. Summary of the Invention

[0027] In this embodiment, when in use, the upper mold driving device 5 is driven, and the upper mold 4 is driven downward by the output end of the upper mold driving device 5, so that the upper mold 4 is close to the lower mold 2. Then, the materials in the upper mold 4 and the lower mold 2 are processed. After the processing is completed, the horizontal conveyor 16 drives the lower mold 2 to move horizontally. During the conveying process, the processed product is lifted up by the single push plate secondary ejection structure 3 until it contacts the limit opening near the left side of the mounting frame 1.

The telescopic tube 17 is stretched until the vacuum suction cup 24 absorbs the product pressed by the mold. After the product pressed by the mold is absorbed, the movable block 26 also contacts the top of the product pressed by the mold, thereby retracting into the inside of the prevention groove, thereby pressing the spring piece 29 to deform and contact the detection end of the pressure sensor 28, and electrically driving the output end of the electric telescopic rod 6 to retract, thereby taking out the processed product. The output end of the electric telescopic rod 6 drives the connecting plate 21 and the product to retract and return to their original position, and again drives the folding frame to return to its original position through the output end of the hydraulic telescopic rod 12, thereby driving the first connecting shaft 25, the mounting plate 8, the second connecting shaft 20, the first hydraulic telescopic rod 12 and the connecting plate 21 to return to their original position, and then outputs again through the output end of the electric telescopic rod 6. At the same time, the vacuum pump 14 stops pumping air, thereby pushing the produced material onto the conveyor 9, and then it is sent to the next outflow through the conveyor 9. After the product is taken out, it is restored to its original position again through the horizontal conveyor 16 for convenient use next time.
