Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, specifically to a demolding device for finished rubber products. Background Technology

[0002] Currently, in injection-molded rubber products, a certain amount of material overflows from the mold cavity due to the gap between the upper and lower molds, forming a flash of a certain width after curing. During demolding, the ejector mechanism acts vertically on the bottom wall of the rubber product and continuously pushes it outward. However, during this process, the flash of the finished product adheres to the mold surface. As the ejector proceeds, shear force is generated between it and the finished rubber product. When fracture occurs, the fracture surface is uncontrollable, which can easily damage the finished rubber product.

[0003] According to the demolding structure of the rubber product injection mold described in patent number CN220923202U, only the flash on the side can be cut off during use. When injection molding finished products such as rubber rings, the edges are still prone to sticking, making it impossible to demold quickly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a demolding device for finished rubber products, which solves the problems mentioned above.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a rubber processing finished product demolding device, including a support frame fixed on the left side of the lower mold and a recycling hopper fixed on the right side of the lower mold, a cutting frame slidably connected to the surface of the support frame, and a conveyor belt connected to the surfaces of the support frame and the lower mold through a rotating roller drive, the surface of the conveyor belt being fixedly connected to the surface of the cutting frame through a connector;

[0006] The inner cavity of the cutting frame is rotatably connected to a turntable driven by a drive mechanism. A cutting head is fixedly connected to the bottom of the turntable, and a pusher is fixedly connected to the right side of the cutting frame. During use, the rubber material is injected into the cavity formed by the lower mold and the upper mold. Then, the injection mechanism pulls the upper mold away from the lower mold. At this time, the overflowing rubber material forms a flash on the edge surface of the lower mold. The rotating roller drives the conveyor belt to move, which drives the cutting frame to move through the connecting parts. This drives the pusher to cut off the connection between the flash and the finished rubber product. While the pusher is cutting the flash, the blower blows air to cool and remove it. The flash falls into the recycling hopper for recycling. At this time, the cutting head also moves to perform a secondary cut. When the cutting frame moves to the correct position, the drive mechanism drives the turntable to rotate. At this time, the cutting head is located on the side of the molded workpiece. The cutting head makes a circular motion to cut off the molded product, preventing it from sticking to the overflowing rubber residue. After cutting, the cutting frame is retracted by the conveyor belt.

[0007] As a further embodiment of this utility model: a sealing gasket is fixedly connected to the bottom of the cutting frame and abuts against the surface of the lower mold. When the cutting frame moves above the lower mold, the sealing gasket is located between the lower mold and the cutting frame to seal.

[0008] As a further embodiment of this utility model: the driving mechanism includes a drive motor fixed on the top of the cutting frame. The surface of the drive motor meshes with the gear on the top of the turntable through a transmission toothed belt. The drive motor drives the transmission toothed belt to rotate, which in turn drives the turntable of a line to rotate, causing the cutting head to make a circular motion, cutting the finished product and separating it from the waste.

[0009] As a further embodiment of this utility model: a blower is fixedly connected to the left side of the cutting frame, which is connected to an external fan via an air pipe, and the blowing direction of the blower is to the right.

[0010] As a further embodiment of this utility model: a discharge groove is provided on the right side of the cutting frame, so that while the push knife is cutting the burrs, the blower can cool and clean them by blowing air out.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. In this utility model, the pusher cuts off the connection between the flash and the finished rubber product. While the pusher cuts the flash, the cutting head also moves to perform a secondary cut. When the cutting frame is in place, the turntable is driven to rotate by the drive mechanism. At this time, the cutting head is located on the side of the formed workpiece. The cutting head makes a circular motion to cut off the formed product, preventing it from sticking to the overflowing rubber residue. It can not only remove the flash, but also assist the formed product in demolding and completely separate it, resulting in better processing effect.

[0013] 2. In this utility model, a discharge groove is provided on the right side of the cutting frame. While the pusher cuts the burrs, the blower blows air to cool and remove them. Attached Figure Description

[0019] Please see Figure 1-3 This utility model provides a technical solution: a rubber processing finished product demolding device, including a support frame 2 fixed on the left side of the lower mold 1 and a recycling hopper 3 fixed on the right side of the lower mold 1. A cutting frame 8 is slidably connected to the surface of the support frame 2. The surfaces of the support frame 2 and the lower mold 1 are both connected to a conveyor belt 6 by a rotating roller 5. The surface of the conveyor belt 6 is fixedly connected to the surface of the cutting frame 8 by a connector 7.

[0020] The inner cavity of the cutting frame 8 is rotatably connected to a turntable 10 driven by a drive mechanism. A cutting head 11 is fixedly connected to the bottom of the turntable 10, and a pusher 9 is fixedly connected to the right side of the cutting frame 8. During use, the rubber material is injected into the cavity formed by the lower mold 1 and the upper mold. Then, the injection mechanism pulls the upper mold away from the lower mold 1. At this time, the overflowing rubber material forms a flash on the edge surface of the lower mold 1. The rotating roller 5 is started to drive the conveyor belt 6 to move, which drives the cutting frame 8 to move through the connecting piece 7, and drives the pusher 9 to move to remove the flash. The joint of the rubber product is cut off. While the pusher 9 cuts the burrs, the blower 12 blows air to cool and clean them. The burrs fall into the recycling hopper 3 for recycling. At the same time, the cutting head 11 also moves to perform a secondary cut. When the cutting frame 8 moves into position, the drive mechanism drives the turntable 10 to rotate. At this time, the cutting head 11 is located on the side of the formed workpiece. The cutting head 11 makes a circular motion to cut off the formed product to prevent it from sticking with the overflowing rubber residue. After the cutting is completed, the cutting frame 8 is retracted by the conveyor belt 6.

[0021] A sealing gasket 4 is fixedly connected to the bottom of the cutting frame 8, which abuts against the surface of the lower mold 1. When the cutting frame 8 moves above the lower mold 1, the sealing gasket 4 is located between the lower mold 1 and the cutting frame 8 to seal.

[0022] The drive mechanism includes a drive motor 15 fixed to the top of the cutting frame 8. The surface of the drive motor 15 meshes with the gear on the top of the turntable 10 through the conveyor belt 14. The drive motor 15 drives the conveyor belt 14 to rotate, which in turn drives the turntable 10 to rotate, which in turn drives the cutting head 11 to make a circular motion, cut the finished product, and separate it from the waste.

[0023] The left side of the cutting frame 8 is fixedly connected to a blower 12 that is connected to an external fan via an air pipe 13, and the blower 12 blows air towards the right.

[0024] The right side of the cutting frame 8 has a discharge slot. While the pusher 9 is cutting the burrs, the blower 12 blows air to cool and remove them.
