Mold for manufacturing special plastic bottle cap by mold pressing and mold pressing equipment

Abstract

The invention discloses a mold for manufacturing a special plastic bottle cap by mold pressing and mold pressing equipment. The mold comprises an upper mold, a lower mold and an outer sleeve, wherein a lower mold cavity is formed in the middle of the lower mold; an inner side wall of the lower mold cavity is provided with a connection annular groove; the upper mold is inserted into the lower mold cavity; the upper mold is inserted into the outer sleeve; the lower end of the outer sleeve is inserted into the connection annular groove; a material ejection block is inserted into the upper mold; the edge of the bottom of the material ejection block is inserted into a groove formed in the inner side wall of the bottom of the upper mold; and the edge of the bottom of the material ejection block is pressed against the top surface of the groove. A key groove is formed in the outer wall on one side of the outer sleeve; the outer side wall of the lower mold is provided with a vertical groove which is aligned to the key groove from top to bottom; and a key is inserted into the key groove and the vertical groove. According to the mold disclosed by the invention, when the upper mold and the lower mold are extruded, a large part of the bottle cap is located on the upper mold after the bottle cap is molded, and the bottle cap can be completely located in the upper mold, so that blanking of the bottle cap can be realized through ventilating and descending a material ejection push rod and the blanking is convenient.

Description

Technical field: [0001] The invention relates to the technical field of bottle cap manufacturing equipment, in particular to a mold and molding equipment for manufacturing special plastic bottle caps by molding. Background technique: [0002] At present, the bottle cap molding machine is an important equipment for making bottle caps for mineral water bottles, beverage bottles, etc. It fixes the lower mold on the push rod, fixes the upper mold on the upper fixing rod, and places the material in the lower mold. The push rod rotates along the raised edge on the edge of the bottom plate, and moves up and down with the raised edge of the edge, so that the lower mold can be lifted up and the upper mold can squeeze the material together to form a bottle cap, and then The push rod continues to descend along the raised edge on the edge of the bottom plate, so that the upper mold and the lower mold are separated, and then the bottle cap on the upper mold is blown off through the blowi...

[0002] At present, the bottle cap molding machine is an important equipment for making bottle caps for mineral water bottles, beverage bottles, etc. It fixes the lower mold on the push rod, fixes the upper mold on the upper fixing rod, and places the material in the lower mold. The push rod rotates along the raised edge on the edge of the bottom plate, and moves up and down with the raised edge of the edge, so that the lower mold can be lifted up and the upper mold can squeeze the material together to form a bottle cap, and then The push rod continues to descend along the raised edge on the edge of the bottom plate, so that the upper mold and the lower mold are separated, and then the bottle cap on the upper mold is blown off through the blowing port on the turntable cylinder, as figure 1 As shown, the main part of its bottle cap molding is between the lower mold 1a and the upper mold 2a. The general bottle cap has a top diameter smaller than the middle part of the bottle cap, and it is easier to fall off from it. However, when the top diameter of the molded bottle cap is larger than the bottle cap When using special bottle caps on other parts of the cap, the bottle cap will stick to the lower mold, so that the bottle cap cannot easily fall off from the lower mold, and the effect is very poor
