Abstract

The invention relates to an inner core-pulling mold. The inner core-pulling mold comprises a front mold and a back mold, wherein the back mold is provided with an inner core pulling mechanism comprising an oil cylinder and a sliding block assembly; and the sliding block assembly comprises a first sliding block, a second sliding block, a third sliding block, a fourth sliding block and a fifth sliding block, wherein the first sliding block is connected with a piston rod of the oil cylinder, the second sliding block and the fourth sliding block are close up towards the middle part of the first sliding block and are connected to the left side and the right side of the first sliding block in a sliding manner, and the third sliding block and the fifth sliding block are close up towards the middle part of the first sliding block and are connected to the left side and the right side of the first sliding block in a sliding manner, thus an inner core pulling operation is finished. Therefore, through the inner core-pulling mechanism, the inner core pulling operation and a return operation can be realized through a reciprocating power of the piston rod flexing in the oil cylinder when a mold is opened; and when a core pulling operation is carried out by lateral parting, a parting operation and the core pulling operation are not limited by mold opening time and ejection time, and the inner core pulling mechanism transfers a workpiece smoothly and carries out the inner core pulling operation more stably by utilizing a high-pressure liquid as power so as to enable mold releasing to be more smooth and simple, and final products are of attractive, fashionable and novel appearance, and are firm, durable, sanitary and environment friendly.
