[0002] The original meaning of a glasses case is a box for glasses; a hard shell case is a sturdy and durable glasses case made of hard material, usually made of ABS, PC, PP and other materials, with the characteristics of anti-fall, anti-pressure, waterproof and dustproof; a soft shell case is a glasses case made of a lighter and softer material than a hard shell case, which can be twisted and deformed, and stored and carried in bags of different shapes; a folding box is a glasses case with two sides designed to overlap and folded into a double layer.

[0003] However, when the flat forming mold of a glasses case with the above structure is in operation, the spring buffering function is to offset the pressing force generated by the stamping belt, and the remaining pressing force will act on the mold itself. Long-term pressing force on the mold will cause damage to the mold. Due to the stamping pressure, the formed model will be adsorbed on the concave mold, and normal handling cannot achieve rapid demolding, which will reduce the efficiency of demolding and thus affect the processing efficiency of the mold.

[0024] Reference Figures 1 to 5The embodiment of the utility model is a plane forming mold of a glasses case, comprising a top plate 1, a male mold 2 is installed at the bottom end of the top plate 1, and a first spring 4 is fixedly installed at the bottom end of the male mold 2, a first connecting plate 5 is fixedly connected to the bottom end of the first spring 4, and a second spring 6 is fixedly connected to the bottom end of the first connecting plate 5, and a second spring 6 is fixedly connected to the bottom end of the second spring 6, and a second connecting plate 7 is fixedly connected to the bottom end of the second connecting plate 7, and a third spring 8 is fixedly connected to the bottom end of the third spring 8, and a female mold 10 is fixedly connected to the bottom end of the third spring 8, and the female mold 10 is installed on the top of the operating table 14. When the male mold 2 coincides with the female mold 10, the first connecting plate 5 and the second connecting plate 7 are pushed up and down by the elasticity of the first spring 4 and the third spring 8, and the second spring 6 is also driven to contract, so that the male mold 2 is pushed by the elasticity of the first spring 4, the second spring 6, and the third spring 8, so that the male mold 2 can offset a certain pressing force after the pressing force.

[0025] The bottom end of the male mold 2 is equipped with a telescopic outer rod 3, and the bottom end of the telescopic outer rod 3 is movably sleeved with a telescopic inner rod 9, and the telescopic inner rod 9 is fixed to the top of the female mold 10. The first spring 4 and the third spring 8 are movably sleeved on the surface of the telescopic outer rod 3 and the telescopic inner rod 9, and the first connecting plate 5 and the second connecting plate 7 are movably sleeved on the surface of the telescopic outer rod 3 and the telescopic inner rod 9. When the male mold 2 moves downward, the telescopic inner rod 9 moves up and down inside the telescopic outer rod 3, and the telescopic outer rod 3 and the telescopic inner rod 9 play a good limiting role on the male mold 2 and the female mold 10, avoiding long-term deviation.

[0026] The first connecting plate 5 has symmetrical through holes 11 on its surface, and a connecting rod 12 is movably sleeved inside the through hole 11, and the connecting rod 12 is fixed to the top of the second connecting plate 7. When the first spring 4 and the third spring 8 are compressed by the pressing force, the connecting rod 12 is also pushed to slide in the through hole 11, so that the connecting rod 12 limits the second spring 6 to avoid misalignment.

[0027] A hydraulic telescopic rod 13 is installed at the bottom of the top plate 1, and the hydraulic telescopic rod 13 is fixed to the top of the operating table 14. Through the hydraulic telescopic rod 13, the male mold 2 is driven to move up and down.

After the male mold 2 and the female mold 10 are pressed and formed, the motor 15 is operated to drive the screw 16 to rotate, so that the threaded block 17 moves on the surface of the screw 16, and then pushes the push block 19 to move, so that the push block 19 slides out of the inner wall of the female mold 10, so that the mold on the inner wall of the female mold 10 after forming is quickly separated.

[0029] A limiting groove 18 is provided inside the female mold 10, and a slide groove 20 is symmetrically provided on the inner wall of the limiting groove 18, and the threaded block 17 is movably sleeved inside the limiting groove 18, and a slider 21 is movably sleeved inside the slide groove 20, and the slider 21 is fixed to the outer wall of the threaded block 17. When the threaded block 17 moves on the surface of the screw rod 16, it also slides up and down in the limiting groove 18, and also drives the slider 21 to slide in the slide groove 20, and the slider 21 plays the role of limiting the threaded block 17, so as to prevent the threaded block 17 from rotating synchronously with the screw rod 16.

[0030] Working principle: First, when the hydraulic telescopic rod 13 drives the top plate 1 to move downward, so that the male mold 2 and the female mold 10 overlap, the first spring 4 and the third spring 8 are driven to contract. Through the elasticity of the first spring 4 and the third spring 8, the first connecting plate 5 and the second connecting plate 7 are pushed up and down, and the second spring 6 is also driven to contract, so that the male mold 2 is pushed through the elasticity of the first spring 4, the second spring 6, and the third spring 8, so that the male mold 2 can offset a certain pressing force after the pressing force, and has a certain buffering effect. After the male mold 2 and the female mold 10 are pressed and formed, the motor 15 is operated to drive the screw 16 to rotate, so that the threaded block 17 moves on the surface of the screw 16, and then the push block 19 is pushed to move, so that the push block 19 slides out of the inner wall of the female mold 10, so that the model on the inner wall of the female mold 10 after forming is quickly detached.
