Abstract

The invention relates to an internally-cut sprue mechanism of a mold, the mold comprises an upper fixing plate, a female mold plate, a female mold core, a male mold core, a male mold plate and a lower fixing plate, the internally-cut sprue mechanism of the mold comprises: an ejector plate arranged on the lower fixing plate; the guide cylinder is arranged on the ejector plate, and the guide cylinder has the function of guiding the ejector plate to eject the cutting needle upwards; the cutting needle is arranged on the ejector plate, and the cutting needle penetrates through the core insert and the inner cutting sprue; the spring structure is arranged at the bottom end of the cutting needle, and the spring structure has elasticity. By means of the internally-cutting sprue mechanism of the mold, the problems that the structure is complex and the mold deforms are solved, the operation efficiency of internally cutting a sprue through the cutting needle is improved, and convenience of ejection and return operation of the cutting needle is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of molds, in particular to an in-cut gate mechanism of a mold. 【Background technique】 [0002] like figure 1 shown, figure 1 It is a schematic diagram of the incision mechanism of the mold in the prior art. The mold includes an upper fixed plate 11, a female template 12, a female mold core 13, a male mold core 14, a male template 15 and a lower fixed plate 16. The incision mechanism of the mold 100 uses the cutting needle 110 to automatically cut the gate inside the mold. When the product is formed in the pressure-holding stage, the cutting needle 110 performs the pre-top operation to complete the in-mold extrusion and shearing gate operation. However, the inner cutting mechanism of the mold When the needle cutting 110 is pre-topped and the gate is inscribed, two ejector plates 120 need to be installed. The ejector plates 120 require a large number of support heads 130 and stop pins 140 with different le...
