Description

Technical Field

[0001] The utility model relates to the technical field of rubber piece production, in particular to a rubber sealing piece punching and demoulding device. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking from adjacent joint surfaces and prevent foreign matter from invading the internal parts of machinery and equipment. They are an indispensable part of equipment and parts. In the production process of small-sized rubber seals, usually a whole or large piece of rubber is first injection molded, and then the rubber sheet is placed in a punching die for punching, and the punched rubber part is separated from the rubber sheet, which greatly improves the molding efficiency of the rubber parts.

[0003] Although the existing technology has high molding efficiency, the rubber parts cannot be directly removed from the rubber sheets after punching, and need to be manually peeled off, which is not only time-consuming and labor-intensive, but also increases the labor intensity of workers and has low work efficiency. Utility Model Content

[0004] The utility model aims to provide a rubber sealing part punching and demoulding device in view of the deficiencies in the prior art. The device has reasonable design and is easy to use. After the rubber part is punched, it can be demoulded automatically, thereby reducing the labor intensity of workers and improving the molding efficiency of the rubber part.

[0005] The utility model adopts the following technical solution to solve the technical problem: a rubber seal punching and demoulding device, comprising a frame, a loading platform for placing a lower mold is arranged in the middle of the frame, a notch is arranged in the middle of the loading platform, a punching upper mold is arranged above the loading platform, a first driving device for driving the punching upper mold to move is arranged on the punching upper mold, an ejection mechanism is arranged below the loading platform, the ejection mechanism comprises a base for placing an ejection unit, the ejection unit comprises a top plate and an ejector column, a second driving device for driving the base to move up and down is arranged below the base, and a through hole for the ejector column to pass through is correspondingly arranged in the mold cavity of the lower mold.

[0006] Furthermore, the notch is provided with a support plate, the stage is provided with a track for the support plate to slide, and the support plate is provided with a third driving device. By providing the support plate, the lower die can be supported during the punching process. After the punching is completed, the third driving device drives the support plate to slide away from the stage, so that the support plate moves out of the notch, which facilitates the action of the ejection mechanism.

[0007] Furthermore, the ejection unit is detachably connected to the base.

[0008] Furthermore, a guide column is provided inside the frame, and the connecting plate at the output end of the first driving device, the base and the guide column are movably connected.

DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0017] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly connected by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0019] like Figure 1 As shown, a rubber seal punching and demolding device of the present embodiment includes a frame 1, a loading platform 3 for placing a lower mold 2 is arranged in the middle of the frame 1, the loading platform 3 is provided with a notch 31, a punching upper mold 4 is arranged above the loading platform 3, the punching upper mold 4 is provided with a first driving device 5 for driving the punching upper mold 4 to move, an ejection mechanism 6 is arranged below the loading platform 3, the ejection mechanism 6 includes a base 62 for placing an ejection unit 61, the ejection unit 61 includes a top plate 611 and a top column 612, a second driving device 63 for driving the base 62 to move up and down is arranged below the base 62, and the mold cavity of the lower mold 2 is correspondingly provided with a through hole for the ejector column 612 to pass through.

[0020] The working principle of the utility model is as follows: the lower mold 2 is placed on the stage 3, corresponding to the notch 31, the rubber sheet is placed on the lower mold 2, the first driving device 5 drives the punching upper mold 4 to move downward to realize the punching and forming of the rubber piece; after the punching is completed, the punching upper mold 4 moves upward to reset; then the second driving device 63 drives the base 62 to move toward the lower mold 2, the ejector 612 passes through the through hole in the mold cavity of the lower mold 2, and the punched and formed rubber piece in the mold cavity is ejected from the lower mold or the rubber sheet, thereby realizing the automatic demolding of the rubber piece. After the demolding is completed, the second driving device 63 drives the base 62 to move downward to reset, so that the ejection unit 61 is separated from the lower mold 2.

[0021] The notch 31 is provided with a support plate 7, the stage 3 is provided with a track 32 for the support plate 7 to slide, and the support plate 7 is provided with a third driving device 8. The support plate 7 can support the lower die 2 during the punching process, and after the punching is completed, the third driving device 8 drives the support plate 7 to slide away from the stage 3, so that the support plate 7 moves out of the notch 31, which is convenient for the ejection mechanism 6 to operate.

[0022] The ejection unit 61 is detachably connected to the base 62 , and the punching upper die 4 is detachably connected to a connecting plate at the output end of the first driving device, so as to facilitate punching and demoulding of different rubber parts.

[0023] A guide column 9 is arranged inside the frame 1, and the connecting plate at the output end of the first driving device 5 and the base 62 are movably connected with the guide column 9. The guide column 9 guides the up and down movement of the punching upper die 4 and the ejection unit 61, thereby improving the punching accuracy of the punching die and the ejection accuracy of the ejection unit 61.

[0024] The stage 3 is provided with a positioning column 33, and a telescopic spring is sleeved on the outside of the positioning column 33. After the lower mold 2 is placed on the stage 3, the telescopic spring can support the lower mold 2. The stage 3 is provided with a clamping device 10, and the clamping device 10 is a pneumatic clamping fixture. The position of the lower mold 2 is positioned by the positioning column 33. The clamping device 10 can clamp the lower mold 2, and the telescopic spring is compressed and contracted. When the punching is completed, the clamping device 10 releases the lower mold 2. Under the action of the telescopic spring, the lower mold 2 is propped up, reducing the force of the lower mold 2 on the support plate 7, so that the third driving device 8 can pull the support plate 7 out of the notch 31, so that the ejection unit 61 can move upward to eject the rubber part.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
