In a further technical scheme, one side of the sliding block, which is far away from the die cavity, is provided with a positioning block, the positioning block is positioned above the connecting block, and the positioning block is connected with the movable die through a connecting shaft.
The positioning block is arranged to position the sliding block on the square edge, so that the sliding block is prevented from sliding out of the mounting opening.
The utility model has the beneficial effects that:
1. in the die closing process, the movable die drives the sliding rod to move downwards, so that the sliding block slides towards one side of the die cavity, and then injection molding is carried out through the injection molding port; after injection molding is finished, the movable die drives the sliding rod to move, the sliding block is driven to move towards the outer side wall of the fixed die, and the wax piece can be taken out through the ejector pin; the movable mold drives the sliding rod to slide, and then the sliding rod drives the sliding block to slide to realize resetting;
2. the mounting hole is obliquely arranged so as to better realize reset;
3. the connecting block is arranged to support the sliding block after sliding;
4. the positioning block is arranged to position the sliding block on the square edge, so that the sliding block is prevented from sliding out of the mounting opening.

Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings.
Example (b):
as shown in fig. 1-4, an automatic resetting mold comprises a movable mold 10, a fixed mold 20 and a resetting device 30, wherein the movable mold 10, the fixed mold 20 and the resetting device 30 are provided with a base at the bottom of the fixed mold 20, mounting openings 21 are provided at two sides of a mold cavity of the fixed mold 20, a supply through hole 22 is provided in each mounting opening 21, the resetting device 30 comprises a sliding block 31 and a sliding rod 32, the sliding block 31 is mounted in the mounting opening 21, a mounting through hole 33 is provided on the sliding block 31, and the sliding rod 32 penetrates through the mounting through hole 33 and the through hole 22 and abuts against the base 60; the movable die 10 is provided with a positioning hole 11 corresponding to the slide rod 32.
In the mold closing process, the slide rod 32 is located in the positioning hole 11 of the movable mold 10, the movable mold 10 moves downwards to drive the slide rod 32 to move downwards, so that the slide block 31 slides towards one side of the mold cavity, and then injection molding is carried out through the injection molding opening; after the injection molding is finished, the movable mold 10 drives the sliding rod 32 to move, the sliding block 31 is driven to move towards the outer side wall of the fixed mold 20, and at the moment, the wax piece can be taken out through the ejector pins; the movable die 10 drives the sliding rod 32 to slide, and then the sliding rod 32 drives the sliding block 31 to slide to realize resetting.
