Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Embodiment one:

the utility model provides a demoulding mechanism for bearing housing, includes base 1, die mold core 2, terrace die mold core 3 and ejector pin 5 subassembly, wherein:

the base 1 is fixed on the workbench and is provided with a sliding groove for sliding the ejector rod 5 assembly;

the ejector rod 5 assembly comprises a sliding seat sliding in the sliding groove and four ejector rods 5 arranged on the sliding seat, and the four ejector rods 5 are uniformly arranged on four corners, so that the four ejector rods 5 are propped against the periphery of the bearing shell 12 and cannot prop up the middle of the bearing shell 12, and the sliding seat can drive the four ejector rods 5 to vertically slide;

the female die core 2 is fixed on the base 1 and is provided with a through hole 7 for the ejector rod 5 to pass through;

the male die core 3 is connected to the female die core 2 in a sliding manner through four guide rods 4, namely, the male die core 3 can vertically slide along the guide rods 4, and the male die core 3 can be pressed down to be matched with the female die core 2 to realize the molding of the bearing shell 12;

the working principle of the application is as follows: the male die core 3 moves downwards along the guide rod 4, the extruded product enables the bearing shell 12 to be shaped, then the male die core 3 moves upwards, then the sliding seat in the ejector rod 5 assembly moves upwards to drive the four ejector rods 5 to move upwards, the product is ejected out of the female die core 2 through the through holes 7, and the four ejector rods 5 are arranged around the bearing shell 12, so that the center of the bearing shell 12 is not influenced, and the ejected bearing shell 12 has lower defective rate.

Embodiment two:

the difference between the die core 2 and the first embodiment is that in the second embodiment, the middle part of the die core 2 is provided with a mounting hole, the mounting hole is provided with an insert 6, the upper end face of the insert 6 is matched with the shape of a product, the outer circumference of the bottom of the insert 6 is provided with a circle of protrusions 8, the bottom of the mounting hole is provided with a circle of steps 9, the insert 6 is mounted from the lower part of the mounting hole during mounting, the protrusions 8 can prop against the steps 9 after the mounting is completed, the insert 6 cannot move upwards, and four through holes 7 are further formed in the insert 6, so that four ejector rods 5 can stretch out from the four through holes 7 to prop against the product so as to push the product out of the die core 2. Thus, the insert 6 is arranged, and the position of the insert 6 is easy to damage, so that when the insert 6 is damaged, the insert 6 can be directly replaced without replacing the whole female die core 2, and the cost is low.
