Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-4 As shown, a mold side core-pulling mechanism with a limiting function comprises: a core-pulling slide 1, on which a side pulling block 2 is connected; a vertical slide block 3, on both sides of which there are positioning grooves 31 that cooperate with the core-pulling slide 1, and the core-pulling slide 1 can move in the horizontal direction by cooperating with the inclined surface of the vertical slide block 3; a transverse slide block 4, which can move in the horizontal direction and is provided with a guide rail 41 and an inclined surface 42 that cooperate with the vertical slide block 3, and the vertical slide block 3 can move along the inclined direction of the inclined surface 42; a limiting block 5, which is arranged at an upper position of the vertical slide block 3 and can limit the vertical slide block 3 in the path of its upward movement; the limiting block 5 includes a first limiting surface 51 that can limit the side of the vertical slide block 3 away from the core-pulling slide block 1 and a top limiting surface 52 that can limit the vertical slide block 3 A second limiting surface 52 for limiting the position of the line; a positioning column 521 which can be inserted into the positioning groove 31 and cooperate with it is provided on the second limiting surface 52; the positioning column 521 is set at an angle that matches the positioning groove 31; a buffer gasket 522 with a diameter larger than the inner diameter of the positioning groove 31 is provided at the connection between the positioning column 521 and the second limiting surface 52; a card groove 511 is provided horizontally along the upper side of the first limiting surface 51, and a flexible card strip is provided at the position corresponding to the vertical slider 3; it also includes a fixed block 6 for positioning and installing the limiting block 5; the limiting block 5 is configured to be adjustably fixed to the fixed block 6 in the vertical direction; it also includes a driving member 7 for driving the horizontal slider 4 to move, and the driving member 7 is configured as an oil cylinder or an air cylinder; the fixed block 6 is arranged between the driving member 7 and the horizontal slider 4.

[0029] By adopting the above technical solution, in the utility model, the main innovation is that by setting the limit block 5, the limit block 5 is used to limit the vertical slider 3 when it moves upward, wherein specifically, the back and top of the vertical slider 3 are limited respectively by two limit surfaces, thereby effectively preventing the side drawer block 2 from being offset due to excessive injection pressure, usually moving backward. And combined with the matching setting of the positioning column 521 and the positioning groove 31, the accuracy of the limit can be further improved, and the movement of the vertical slider 3 can be effectively prevented, and the limiting effect is better.
