Thus, the in-orbit core retracting mechanism 1 thoroughly demolds the inner surface 112 of the product 11 through three core pulling, so that the internal structure of the product 11 is not damaged.

The first direction 16 is a demolding direction of the first surface 113 of the product 11, and the first direction 16 may be a direction perpendicular to the first surface 113 of the product 11. The second direction 17 is the demolding direction of the second surface 114 of the product 11, and the second direction 17 may be a direction perpendicular to the second surface 114 of the product 11.

In this embodiment, the cross section of the first slider 12 is trapezoidal, two second sliders 13 are disposed, the second sliders 13 are respectively disposed on the surface of the side 121 of the trapezoid in the cross section of the first slider 12, and the side 121 forms an included angle with the second direction 17. In one aspect, the side 121 facilitates the resolution of the driving force in the second direction 17 into a component in the first direction 16 and a component in the second direction 17. On the other hand, the side 121 facilitates the sliding extraction of the first slider 12 from the second slider 13.

In one embodiment, the in-orbit retraction mechanism 1 further comprises a base plate 15. The base plate 15 is provided with a first guide rail 151, the first guide rail 151 comprises a first rail 152 and a second rail 153, the first rail 152 extends along the first direction 16 for a first distance 154, the second rail 153 extends along the second direction 17 for a second distance 155 from the tail end of the first rail 152, the first guide rail 151 is in abutting connection with the second slider 13, and the first guide rail 151 can guide the second slider 13 to move according to the paths of the first rail 152 and the second rail 153.

The base plate 15 is provided with a groove 188, the sliding block seat 183 is fixedly connected with the first sliding block 12, and the sliding block seat 183 and the first sliding block 12 slide along the second direction 17 on the surface of the groove 188. The telescopic end 187 of the cylinder 181 is fixedly connected to the slide block base 183 to drive the first slide block 12 to slide in the groove 188. The shape of the block base 183 may be a cone to enhance the strength of the block base 183, and prevent the block base 183 from being broken when the driving force of the cylinder 181 is applied to the block base 183. The sliding block seat 183 is beneficial to avoiding the direct connection between the oil cylinder 181 and the first sliding block 12, thereby protecting the first sliding block 12 and facilitating timely replacement of the first sliding block 12 after abrasion, and facilitating smooth demolding of the product 11.

Optionally, the power assembly 18 may further include a bead 184, a fixed block 182, a first sensor 185, and a second sensor 186.

The fixed block 182 facilitates the precision of movement of the telescoping end 187 of the lift cylinder 181 in the first direction 16.

The first sensor 185 and the second sensor 186 are fixed to the slider seat 183. The first sensor 185 is used to sense a signal that the first slider 12 is moving into position toward the interior surface 112 proximate to the product 11, thereby stopping the first slider 12 in the proper position on the interior surface 112 of the product 11 to shape the product 11. The second sensor 186 is used to sense a signal that the first slider 12 is moving into position toward the inner surface 112 away from the product 11, thereby stopping the first slider 12 to facilitate demolding of the product 11.

The first rail 152 is provided with a clamp end 1511 and the second rail 153 is provided with an open end 1512. When the first slider 12 moves into the product 11, the first slider 12 drives the second slider 13 to move to a position corresponding to the clamping end 1511 of the first rail 152, and the clamping end 1511 abuts against the second slider 13 to stop the movement of the second slider 13, at this time, the second slider 13 is attached to the first surface 113 and the second surface 114 of the product 11. When the first slider 12 moves to a position away from the product 11, the first slider 12 drives the second slider 13 to move to a position opposite to the die opening end 1512 of the second rail 153, and the die opening end 1512 abuts against the second slider 13 to stop the movement of the second slider 13, at this time, the second slider 13 is released from the first surface 113 and the second surface 114 of the product 11.

Alternatively, the second slide 13 may be stopped at a corresponding position in the first rail 152 by the first sensor 185 and the second sensor 186, respectively, or the first sensor 185 cooperates with the clamp end 1511 to stop the second slide 13 at the clamp position and the second sensor 186 cooperates with the clamp end 1512 to stop the second slide 13 at the clamp position.

In one embodiment, the in-orbit retraction mechanism 1 further comprises a guide rod 159, and the guide rod 159 is a cylinder. The guide rod 159 is fixedly connected with the second slider 13, the first guide rail 151 is shaped as an elongated hole, and the circumferential surface of the guide rod 159 is matched with the inner surface 112 of the first guide rail 151.

In this embodiment, the guide rod 159 is matched with the first guide rail 151 through the hole shaft, which is favorable for improving the position accuracy of guiding, so that the core pulling of the in-orbit core-shrinking mechanism 1 is smooth, and the product 11 is not damaged. When the first slider 12 and the second slider 13 slide along the side 121, the guide rod 159 splits the driving force in the second direction 17 along the first track 152 into a component force in the first direction 16, and the component force in the first direction 16 moves the second slider 13 in the first direction 16.

In other embodiments, a roller may be disposed at one end of the guide rod 159 contacting the first guide rail 151, where the roller slides in the first guide rail 151, so as to reduce friction between the guide rod 159 and the first guide rail 151 when moving, and facilitate the smooth movement of the second slider 13, so that the core pulling of the in-orbit core-shrinking mechanism 1 is smooth, and the product 11 is not damaged.

The step 131 includes a first face 133 disposed along the first direction 16 and a second face 134 disposed along the second direction 17, and the third rail 132 is disposed on the second face 134. When the second slider 13 moves to the position of the mold clamping end 1511, the third slider 14 is attached to the first face 133 and the second face 134 of the step 131; when the second slide 13 has been moved a first distance 154 from the clamp end 1511, the second slide 13 moves along the third rail 132 to space the first face 133 of the step 131 from the third slide 14; when the second slider 13 is moved to the position of the open end 1512, the third slider 14 approaches the first face 133 along the third guide rail 132. The provision of the step 131 facilitates the core pulling behind the third slider 14 and thus the corner surface 115 is released behind the first surface 113 and the second surface 114, allowing a smooth release of all the inner surfaces 112 of the product 11.
