[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-6As shown, the demolding mechanism for processing the steering gear bushing first includes a bushing body 1. In the present application, a bushing receiving ring 4 is installed at the end of the bushing body 1, wherein a through body through hole 2 is opened on the bushing body 1, and a non-through body slot 3 is opened on the bushing body 1, that is, during production demolding, the bushing body 1 and the body through hole 2 can achieve the demolding effect when they are moved longitudinally. However, for the body slot 3, if the body slot 3 is moved longitudinally directly, the body slot 3 will move longitudinally on the mold, and the slot size of the body slot 3 will become larger, affecting the structural integrity of the bushing body 1. Therefore, when the body slot 3 needs to be removed from the mold, the bushing body 1 needs to be slowly removed from the mold, affecting the processing efficiency of the bushing.

[0025] As a further embodiment of the present application, the present application includes a lower template 5, wherein a mold cavity is opened on the lower template 5, and a molding substrate 61 for use with the main body groove 3 is fixed on the side wall of the mold cavity, wherein a molding plane 62 for realizing the molding of the main body groove 3 is provided on the molding substrate 61, wherein a demolding arc surface 63 is fixed to the bottom of the molding plane 62, which is used to realize the molding of the main body groove 3 and the demolding of the bushing body 1. When the bushing body 1 moves upward, the main body groove 3 slides on the demolding arc surface 63, which will squeeze the bushing body 1, so that the bushing body 1 is squeezed under the action of the main body perforation 2 and shifted toward the center position, thereby realizing the demolding of the bushing body 1, and avoiding the downward pulling effect on the main body groove 3, thereby ensuring the integrity of the bushing body 1.

[0026] Specifically, the lower mold plate 5 includes a mold plate base 51 , wherein a mold cavity is opened on the mold plate base 51 , wherein a demoulding mechanism 6 for demoulding the bushing body 1 is arranged inside the mold plate base 51 .

[0029] Specifically, when the demolding bottom plate 611 moves longitudinally, the bottom of the bushing body 1 adheres to the demolding bottom plate 611, so that the bottom of the bushing body 1 is subjected to a downward pulling force. When the bushing body 1 is stretched downward, it is gradually separated from the demolding bottom plate 611. At the same time, the bushing body 1 is gradually separated from the inner wall of the mold cavity, thereby realizing the demolding effect of the bushing body 1.

[0031] In order to further realize the unified demolding of the bushing bodies 1 in multiple mold cavities, a connecting cavity 612 is opened on the bottom side of the mold cavity in the present application, wherein the connecting cavity 612 is longitudinally slidably provided with a cooperative rod 613, wherein the cooperative rod 613 is respectively connected between two connecting rods 610, and when the connecting rod 610 moves longitudinally, under the coordinated action of the cooperative rod 613, the demolding bottom plate 611 is driven to uniformly move longitudinally, thereby realizing the unified demolding of multiple bushing bodies 1.

[0032] When the utility model is in use, when the bushing body 1 is demoulding, the bushing receiving ring 4 is restricted above the mold cavity, and the oil enters the oil cavity 64 at this time, which is used to realize the longitudinal movement of the piston 65, so that the sliding rod 66 moves longitudinally, and the sliding block 67 moves longitudinally inside the sliding cavity 68, so as to realize the longitudinal movement of the connecting rod 610, so that the demoulding bottom plate 611 and the bushing body 1 are separated, that is, when the demoulding bottom plate 611 moves longitudinally, the bottom of the bushing body 1 is adhered to the demoulding bottom plate 611, and under the restriction of the bushing receiving ring 4, the bottom of the bushing body 1 is subjected to a downward pulling force, and when the bushing body 1 is stretched downward, it is gradually separated from the demoulding bottom plate 611, and at the same time, the bushing body 1 undergoes a small amount of deformation due to the longitudinal tensile force, and gradually The bushing body 1 is gradually separated from the inner wall of the mold cavity, and then due to its own rubber elasticity, the bushing body 1 will return to its original state, thereby realizing the demoulding effect of the bushing body 1; then, an upward pulling force is applied to the bushing receiving ring 4, and the main body groove 3 slides on the demoulding arc surface 63, which will squeeze the bushing body 1, so that the bushing body 1 is squeezed under the action of the main body perforation 2, and the bottom of the bushing body 1 is deformed, that is, the bottom of the bushing body 1 is offset toward the center position, thereby realizing the demoulding of the bushing body 1, and can avoid the direct plane pulling effect on the main body groove 3 downward during demoulding, thereby ensuring the integrity of the bushing body 1, and through the setting of the demoulding arc surface 63, the demoulding effect of the bushing body 1 can be quickly realized, and the demoulding efficiency of the bushing body 1 is guaranteed while ensuring the integrity of the main body groove 3.
