Description

Technical Field

[0001] The utility model relates to the technical field of rubber hemming, in particular to a mold for rubber hemming processing. Background Art

[0002] The rubber edging of the seat armrest is usually made by injection molding or pressing rubber materials along the edge of the seat armrest. This edging can increase the comfort, durability and aesthetics of the seat armrest, and can reduce the discomfort when it comes into contact with the human body. These rubber edgings are usually directly processed into the seat armrest during the seat manufacturing process, and can also be used as replaceable accessories for later replacement.

[0003] The prior art has the following deficiencies: the existing rubber edging of the seat armrest requires the use of a specific rubber edging processing mold, and the traditional seat armrest rubber edging processing mold is mostly composed of two molds. Since there is inevitably a gap between the two molds, after injection molding or pressing, the two molds will leave a circle of parting line on the surface of the rubber edging of the armrest, which greatly affects the feel and aesthetics of the rubber edging of the seat armrest; in order to ensure the production quality of the seat armrest, a separate process for removing the parting line is added, which makes the production process of the rubber edging of the seat armrest too complicated, greatly reducing the efficiency of the rubber edging of the seat armrest. Therefore, the traditional seat armrest rubber edging processing mold has the problem that the parting line is easily generated on the edging surface, resulting in an overly complicated production process and too low production efficiency.

[0004] Therefore, it is necessary to invent a rubber hemming processing die. Utility Model Content

[0005] To this end, the utility model provides a mold for rubber edging processing. By rotating the third mold and splicing it with the first mold, the cutting blade in the third mold cuts off the excess part of the side of the rubber edging, so as to solve the problem that the traditional mold for processing rubber edging of seat armrests is prone to produce a mold line on the surface of the rubber edging, resulting in excessive complexity of the subsequent production process and excessively low production efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold for rubber edging processing, comprising a first mold, a second mold, a third mold and a seat armrest, an armrest connecting rod is installed on one side of the seat armrest, the first mold and the second mold are rotatably connected, the rubber raw material and the seat armrest are placed in the first mold, and the second mold is rotated to press the rubber raw material into a rubber edging. The first mold and the third mold are also rotatably connected, and a cutting blade is provided on the inner wall of the third mold. Rotating the third mold can drive the cutting blade to cut the excess part of the rubber edging.

[0007] Preferably, the top surface of the first mold is provided with a groove capable of embedding the seat armrest, and a gap for molding the rubber edging is provided between the inner wall of the groove on the top surface of the first mold and the outer wall of the seat armrest.

[0008] Preferably, a first rotating plate is fixedly mounted on one end of the first mold close to the second mold, and a second rotating plate is fixedly mounted on one end of the first mold close to the third mold.

[0009] Preferably, a third rotating plate is fixedly mounted on one end of the second mold close to the first mold, and the third rotating plate is rotatably connected to the first rotating plate. A first handle is fixedly mounted on one end of the second mold away from the first mold.

[0010] Preferably, a fourth rotating plate is fixedly mounted on one end of the third mold close to the first mold, the fourth rotating plate is rotatably connected to the second rotating plate, and a second handle is fixedly mounted on one end of the third mold away from the first mold.

[0011] Preferably, a groove capable of embedding a seat armrest is provided on one side of the second mold, a slot for the armrest connecting rod to pass through is provided on the bottom surface of the groove of the second mold, and a gap for molding rubber edging is provided between the inner wall of the groove of the second mold and the outer wall of the seat armrest.

[0012] Preferably, a groove capable of embedding a seat armrest is provided on one side of the third mold, and a slot for allowing an armrest connecting rod to pass through is provided on the bottom surface of the groove of the third mold.
