Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a 5RT front top mold opening mechanism for a vacuum vulcanizing machine. Background Technology

[0002] With the development of the rubber industry, users have higher and higher requirements for rubber molding equipment. The more products produced per mold, the faster the delivery time will be. Therefore, the ability to meet the mold opening function of more layers has become a trend.

[0003] Currently, in the rubber vacuum forming machine industry, mold opening methods are mainly divided into two categories: front-ejection mold opening and track mold opening. Each category can be further subdivided into several different types, and each mold opening design has its own advantages and disadvantages. For example, when using a mold with an ejector-type mold opening method, a front-ejection mold opening mechanism can be added to the slide rail, but it can usually only install a maximum of 3 to 4 layers of mold. When using a hinge-type mold opening method, which is a track mold opening method, it is only suitable for 2-layer mold opening and cannot open 5-layer molds.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0050] like Figures 1-32As shown, this utility model provides a 5RT front-top mold opening mechanism 100 for a vacuum vulcanizing machine, including at least two upper plates 1. Two slide rails 2 are respectively provided on one side of each of the two upper plates 1. Inlet / outlet templates 3 are provided on the two slide rails 2. The mechanism includes an upper mold lifting mechanism 4, a side mold lifting mechanism 5, and a lower mold pressing mechanism 6. The upper mold lifting mechanism 4, the side mold lifting mechanism 5, and the lower mold pressing mechanism 6 are all located on the two upper plates 1. The upper mold lifting mechanism 4 is located above the side mold lifting mechanism 5, and the lower mold pressing mechanism 6 is located below the side mold lifting mechanism 5. The upper mold lifting mechanism 4 lifts the first layer of the mold once, the side mold lifting mechanism 5 lifts the second and third layers of the mold twice, and the lower mold pressing mechanism 6 presses the mold down once. The upper mold lifting mechanism 4 includes a first front push column 41, an upper mold lifting middle plate 42, an upper mold lifting base plate 43, and an upper mold lifting cylinder 44. The lower end of the first front push column 41 is fixed to the upper plate 1, and the upper end of the first front push column 41 passes through the upper mold lifting middle plate 42 and connects to the upper mold lifting base plate 43. The first front push column 41 fixes the upper mold lifting base plate 43 to the upper plate 1. The upper mold lifting middle plate 42 rises or falls without tilting under the guidance of the first front push column 41. The upper mold lifting cylinder 44 is located on the upper mold lifting base plate 43, and the upper mold lifting piston rod of the upper mold lifting cylinder 44 is connected to the upper mold lifting middle plate 42. The upper mold lifting piston rod of the upper mold lifting cylinder 44 drives the upper mold lifting middle plate 42 to rise or fall. The upper lifting mold plate 42 is symmetrically provided with a first upper lifting template 45 and a second upper lifting template 46 on both sides. Before demolding, the upper lifting mold piston rod drives the upper lifting mold plate 42 to descend, and the upper lifting mold plate 42 drives the first upper lifting template 45 and the second upper lifting template 46 to descend above the entry and exit template 3. During demolding, the two ends of the first layer of the mold are respectively clamped in the first upper lifting template 45 and the second upper lifting template 46. The upper lifting mold bottom plate 43 is fixed to the upper plate 1 by the first front top column 41. The action of the upper lifting mold piston rod drives the upper lifting mold plate 42 to rise. The upper lifting mold plate 42 rises stably under the guidance of the first front top column 41. At this time, the rise of the upper lifting mold plate 42 drives the first upper lifting template 45 and the second upper lifting template 46 to rise. The first and second upper lifting templates 45 and 46 rise to lift the first layer of the mold and detach it from the mold, thus achieving one lifting of the first mold. The side top mold mechanism 5 is fixed between the second upper plate 1 and the lower connecting plate 8 by the third front top column 55 and moves up and down on the second upper plate 1. Specifically, the two ends of the second layer of the mold are respectively clamped on the first side top plate 51. The piston rod of the first side top plate of the first side top plate cylinder 54 of the side top mold mechanism 5 moves to drive the first side top plate 51 to rise. The first side top plate 51 drives the second front top column 52 and the first layer plate 53 to rise synchronously. The first layer plate 53 rises stably under the guidance of the third front top column 55. The stable rise of the first side top plate 51 lifts the second layer of the mold, thus achieving one side lifting.After the second layer of the mold is lifted and contacts the flipping bearing 512 on the mold-lifting bracket 510 of the side top mold mechanism 5, the second layer of the mold continues to rise and flips under the action of the flipping bearing 512 to remove the product. After the product is removed, the piston rod of the first side top plate moves to drive the first side top plate 51 to descend. The first side top plate 51 drives the second front top column 52 and the first layer plate 53 to descend synchronously. The first layer plate 53 descends stably without tilting under the guidance of the third front top column 55. The descent of the first side top plate 51 prepares for the next side top. The two ends of the third layer of the mold are respectively clamped on the second side top plate 56 of the side top mold mechanism 5. The piston rod of the second side top plate cylinder 59 of the side top mold mechanism 5 moves to drive the second layer plate 58 to rise. The lifting mechanism causes the fourth front ejector column 57 and the second side ejector plate 56 to rise synchronously. The rise of the second side ejector plate 56 lifts the third layer of the mold, achieving a second side ejection. After the third layer of the mold is lifted, the piston rod of the second side ejector plate moves to drive the second layer plate 58 to fall. The fall of the second layer plate 58 drives the fourth front ejector column 57 and the second side ejector plate 56 to fall synchronously, preparing for the next side ejection. The piston rod of the lower ejector plate cylinder 63 of the lower ejector plate mechanism 6 moves to drive the lower ejector plate 62 to rise. The lower ejector plate 62 rises stably under the guidance of the ejector plate guide column 64. The rise of the lower ejector plate 62 inserts the ejector pin above the lower ejector plate 62 into the mold groove below the mold to eject the product, that is, to perform one lower ejection of the mold, saving time and effort, and realizing the opening of five layers of the mold.

The piston rod of the first side top plate 51 of the first side top plate cylinder 54 moves, causing the first side top plate 51 to rise. The first side top plate 51 drives the second front top column 52 and the first layer plate 53 to rise synchronously. The first layer plate 53 rises stably under the guidance of the third front top column 55. The stable rise of the first side top plate 51 lifts the second mold layer, achieving one side lift. After the second mold layer is lifted, the piston rod of the first side top plate moves, causing the first side top plate 51 to fall. The first side top plate 51 drives the second front top column 52 and the first layer plate 53 to fall synchronously. The first layer plate 53 falls stably without tilting under the guidance of the third front top column 55. The fall of the first side top plate 51 prepares for the next side lift.

The two ends of the third mold layer are respectively clamped on the second side top plate 56. The piston rod of the second side top plate moves to drive the second layer plate 58 to rise. The rise of the second layer plate 58 drives the fourth front top column 57 and the second side top plate 56 to rise synchronously. The rise of the second side top plate 56 lifts the third mold layer of the mold, realizing the second side lifting. After the third mold layer is lifted, the piston rod of the second side top plate moves to drive the second layer plate 58 to fall. The fall of the second layer plate 58 drives the fourth front top column 57 and the second side top plate 56 to fall synchronously. The fall of the second side top plate 56 prepares for the next side lifting.

[0055] Preferably, the system further includes a reinforcing plate 9. The second front top column 52 passes through the reinforcing plate 9 above the two upper plates 1 and is fixed to the first side top plate 51.
