The plurality of side-hole insert rods 8 are all located within the core-pulling block 7 and one end passes through the core-pulling block 7. An inclined through-hole 12 is opened at the other end of the sliding seat 6. A cut 21 is opened on one side of the inclined through-hole 12. A core-pulling oil cylinder 10 is installed on the right side of the lower mold frame 2. A spherical rod 9 is connected to the piston rod of the core-pulling oil cylinder 10. The spherical head of the spherical rod 9 is inserted into the inclined through-hole 12, and the rod part of the spherical rod 9 passes through the cut 21.

[0023] A hole-position insert rod 14 that slides up and down is installed at the upper part of the upper mold core 3. The lower end of the hole-position insert rod 14 is inserted into the mold cavity. A hole-position oil cylinder 15 connected to the hole-position insert rod 14 is installed at the upper end of the upper mold frame 1.

[0024] A runner cone 19 is installed at the upper end of the lower mold frame 2 on the left side of the lower mold core 4. A runner is provided between the runner cone 19 and the mold cavity. A barrel 18 sleeved outside the runner cone 19 is installed inside the upper part of the upper mold frame 1.

[0025] A mold foot 20 is installed on each side of the lower end of the lower mold frame 2. A top plate assembly 17 that slides up and down is installed between the two mold feet 20. A plurality of ejector rods 16 that are vertically inserted into the mold cavity are provided on the top plate assembly 17.

[0026] A jack is opened at the lower end of the lower mold frame 2. A connecting rod 23 is inserted into the jack from bottom to top.

[0029] A coupling 11 is used to connect the rod part of the spherical rod 9 and the piston rod of the core-pulling oil cylinder 10, which can realize the quick connection between the two components.

[0030] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0031] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the drawing is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used here will be made.

[0032] In addition, it should be noted that the use of terms such as "first", "second", etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.
