[0006] By operating the motor, the screw is driven to rotate, so that the thread block moves on the surface of the screw, and then the push block is pushed to move, so that the push block slides out of the inner wall of the die, so that the molding model adsorbed on the inner wall of the die can be quickly detached. Through operation, demolding can be carried out conveniently and efficiently, making demolding faster, thereby improving the efficiency of demolding.

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figures 1 to 4 The embodiment of the utility model is an injection mold with a demoulding structure, including a top plate 1, a connecting rod 2 is fixedly installed at the bottom end of the top plate 1, a cushion block 3 is fixedly installed at the bottom end of the connecting rod 2, and a concave mold 4 is installed at the bottom end of the cushion block 3, a motor 5 is installed at the top end of the top plate 1, and a screw 6 is fixedly installed at the bottom end of the motor 5, a threaded block 7 is threadedly connected to the surface of the screw 6, and a push block 9 is fixedly connected to the top of the threaded block 7, and the push block 9 is movably sleeved on the top of the inner wall of the concave mold 4. The motor 5 is operated to drive the screw 6 to rotate, so that the threaded block 7 moves on the surface of the screw 6, and pushes the push block 9 to move, so that the push block 9 slides out of the inner wall of the concave mold 4, so that the molding model adsorbed on the inner wall of the concave mold 4 can be quickly detached.

[0024] A limiting groove 8 is provided inside the cushion block 3, and a first slide groove 10 is symmetrically provided on the inner wall of the limiting groove 8, and the threaded block 7 is movably sleeved inside the limiting groove 8, and a first slider 11 is movably sleeved inside the first slide groove 10, and the first slider 11 is fixed to the outer wall of the threaded block 7. When the threaded block 7 moves on the surface of the screw rod 6, it also slides up and down in the limiting groove 8, and also drives the first slider 11 to slide in the first slide groove 10, and the first slider 11 plays the role of limiting the threaded block 7, so as to prevent the threaded block 7 from rotating synchronously with the screw rod 6.

[0025] A hydraulic rod 12 is symmetrically mounted on the bottom of the top plate 1, and the top of the bottom plate 13 is mounted on the hydraulic rod 12. The top plate 1 is driven to move up and down by the hydraulic telescopic action of the hydraulic rod 12.

[0026] A fixing plate 14 is fixedly installed on the top of the bottom plate 13, and a second slide groove 15 is symmetrically opened on the inner wall of the fixing plate 14. A second slider 16 is movably sleeved inside the second slide groove 15, and the second slider 16 is fixed on the outer wall of the punch 17, and the punch 17 is movably sleeved on the top of the fixing plate 14. When the injection hole 18 is injected between the punch 17 and the die 4, a model is formed. After the punch 17 has no pressing force, the punch 17 is pushed upward by the elasticity of the telescopic spring 20, so that the punch 17 slides upward on the inner wall of the fixing plate 14, so that the molded model is separated from the surface of the punch 17 and adsorbed on the inner wall of the die 4.

[0027] The bottom plate 13 and the outer wall of the male mold 17 are provided with an injection hole 18. The material is injected into the middle of the male mold 17 and the female mold 4 through the injection hole 18, thereby forming a model.

Through the elasticity of the telescopic spring 20, after the die 4 and the punch 17 form a model, the punch 17 is pushed upward to separate the model from the surface of the punch 17.

[0029] Working principle: First, when the injection hole 18 is injected between the punch 17 and the die 4, a model is formed. The hydraulic rod 12 is hydraulically extended and moved upward, driving the die 4 to move upward. After the punch 17 has no pressing pressure, the extension spring 20 pushes the punch 17 upward, driving the second slider 16 in the second slide groove 15, so that the punch 17 slides upward on the inner wall of the fixed plate 14, so that the molded model is separated from the surface of the punch 17 and adsorbed on the inner wall of the die 4. When the motor 5 is operated, the screw 6 is driven to rotate, so that the threaded block 7 moves threadedly on the surface of the screw 6, and then the push block 9 is pushed to move, so that the push block 9 slides out of the inner wall of the die 4, so that the molded model adsorbed on the inner wall of the die 4 is quickly separated.
