Kettle forming mold

Abstract

The invention belongs to the technical field of injection molds and relates to a kettle forming mold. The kettle forming mold is used for forming a kettle with a spout and comprises a male mold insert, a female mold insert and a plurality of sliders, wherein the male mold insert and the female mold insert are opposite to each other up and down; a plurality of sliders are spliced around the male mold insert and the female mold insert; the male mold insert comprises a body shaped like a cone frustum; the body is provided with a fine end and a thick end; the fine end is close to the female mold insert; the thick end is far from the female mold insert; a spout formed body is integrally formed at the side of the thick end of the body. The kettle forming mold has the beneficial effects that as the spout formed body and the body are integrally formed, the body and the spout of the kettle can be connected in a seamless manner and the heat from the spout formed body and the body is directly conducted, thus avoiding generating gas marks in the transition region of the body and the spout of the kettle due to surface temperature difference and then ensuring the product quality and the demolding effects.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a kettle forming mold for preventing the occurrence of the kettle spout. Background technique [0002] figure 1 The product is a kettle 1 formed by injection molding. As can be seen from the structure of the product, its basic structure is a cylindrical kettle body 11, and an outwardly protruding spout 12 is provided at the opening of the kettle body 11. Such as figure 2 As shown, the usual molding of this kettle 1, the internal molding of the kettle body 11 and the spout 12 uses different male mold inserts (the first insert 21a and the second insert 21b). The first insert 2a and the second insert 2b are separated successively, which can avoid the trouble of material removal due to the tightness of the outer mouth of the pot body 11, but brings another problem: because in order to make the injection molded body cool and form in the mold, the first insert Cooling water...

AI Technical Summary

Problems solved by technology

like figure 2 As shown, the usual molding of this kettle 1, the internal molding of the kettle body 11 and the spout 12 uses different male mold inserts (the first insert 21a and the second insert 21b). The first insert 2a and the second insert 2b are separated successively, which can avoid the trouble of material removal due to the tightness of the outer mouth of the pot body 11, but brings another problem: because in order to make the injection molded body cool and form in the mold, the first insert Cooling water will pass through the inside of the part 21a. Since the first insert 21a and the second insert 21b are split structures, the thermal conductivity between the two is poor, and the temperature difference between the injection molding material and the surface of the insert will form water vapor, which in turn will cause the spout 12 Air marks are produced in the transition area, which makes the strength of this area lower, which will not only make the product look bad, but also cause it to break during demoulding
