[0001] The present invention relates to a mold for shearing spring rubber products. The present invention can realize rapid mold loading and mold unloading of a multi-cavity mold for shearing springs, greatly improve production efficiency, and reduce labor intensity. The present invention has been applied to production, with good reliability and strong practicability. Background Art

[0002] A rubber product mold is a mold for producing rubber products. Reasonable mold design can greatly improve production efficiency and reduce labor intensity. Summary of the Invention

[0003] Technical Solution:

[0004] In order to solve the problem of low production efficiency of shearing spring rubber products, the present invention adopts a new design scheme. The present invention relates to a mold for shearing spring rubber products, which is characterized by consisting of an upper mold (1), a middle mold 1 (2), a middle mold 2 (3), a lower mold (4), and a middle mold connecting sliding rod (5).

[0005] The purpose of the present invention is to be simple and easy to operate, have high production efficiency, and low labor intensity when using the mold for shearing spring rubber products for production.

[0006] The upper mold (1) is positioned with the middle mold 1 (2) and the middle mold 2 (3) through positioning pins. The positioning pins are components on the middle mold 1 (2) and the middle mold 2 (3), and their function is to conduct guiding and positioning when the mold is closed.

[0007] The middle mold 1 (2) and the middle mold 2 (3) are positioned with the lower mold (4) through positioning pins. The positioning pins are components on the middle mold 1 (2) and the middle mold 2 (3), and their function is to conduct guiding and positioning when the mold is closed.

[0008] The middle mold 1 (2) and the middle mold 2 (3) are connected together through the middle mold connecting sliding rod (5). The middle mold connecting sliding rod (5) has threads, and the middle mold 2 (3) has threaded holes. The middle mold 2 (3) is fixed to the middle mold connecting sliding rod (5) through threads. The middle mold 1 (2) slides along the middle mold connecting sliding rod (5). When loading the mold and vulcanizing, the middle mold 1 (2) slides to the closest position to the middle mold 2 (3) to form the shape and size of the product mold cavity; when taking out the product after vulcanization is completed, the middle mold 1 (2) slides to the farthest position from the middle mold 2 (3), and the product can be taken out very conveniently.

[0009] The upper mold (1) is provided with screw holes and is fixed on the upper plate of a 3RT flat vulcanizing machine through the screw holes. The middle mold 1 (2) and the middle mold 2 (3) are quickly demolded through the middle mold fixing device of the 3RT flat vulcanizing machine, and the lower mold (4) is fixed on the lower plate of the 3RT flat vulcanizing machine through a fixing device.

[0010] The present invention can realize the rapid mold loading and unloading of the shear spring multi-cavity mold, greatly improve the production efficiency, and reduce the labor intensity. The present invention has been applied to production, with good reliability and strong practicability.

[0011] The following further describes the present invention with reference to the accompanying drawings. Description of the Drawings
