Novel anticollision injection mold

Abstract

The invention provides a novel anticollision injection mold including a positioning ring, an upper fixed plate and the like and characterized in that the novel anticollision injection mold also includes a limit controller, a limit block, a photoelectric switch, a detachable sprue bush and a counter; the upper fixed plate is provided with the positioning ring; the positioning ring is provided with the detachable sprue bush; a pouring gate is arranged below the detachable sprue bush; a female mold is arranged below the upper fixed plate, one side of the female mold is provided with a guide pillar, and the other side of the female mold is provided with the limit block. The limit controller, the limit block, the photoelectric switch, the detachable sprue bush and the counter are added; if an ejection rod is not reset, a case that the ejection rod is not reset and the mold is assembled again to eject the mold to be bad is avoided; the photoelectric switch is triggered when the mold is opened, the counter is allowed to count, the effectiveness of piece automatic counting is achieved, artificial recording is not needed, and the manpower is saved; after injection molding, the sprue bush can be dismounted alone and is cleaned, the whole positioning ring is not required to be dismounted, and a plenty of time is saved.

Description

technical field [0001] The invention relates to an injection mold, in particular to a novel anti-collision injection mold. Background technique [0002] In modern society, the use of plastic products is becoming more and more extensive. Injection mold is a kind of tool ; It is also to give plastic products a complete structure and accurate size tool ,The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a pouring system. And the cavity, when the mold is opened, the movable mold and the fixed mold are separated, and the plastic product is ejected through the ejector pin, but it is often difficult to reset after the ejector pin is ejected, and the mold will be damaged when the mold is closed again...

[0002] In modern society, the use of plastic products is becoming more and more extensive. Injection mold is a kind of tool ; It is also to give plastic products a complete structure and accurate size tool ,The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a pouring system. And the cavity, when the mold is opened, the movable mold and the fixed mold are separated, and the plastic product is ejected through the ejector pin, but it is often difficult to reset after the ejector pin is ejected, and the mold will be damaged when the mold is closed again. This hidden danger exists in all existing injection molds. ; and after most molds are injected, residual waste is likely to be left at the gate, which is very difficult to remove after cooling and solidifying at the gate, and cleaning requires the staff to remove the entire positioning ring, which is very time-consuming and laborious; most of the molds used in factories now are It does not have the counting function, and the number of produced parts needs to be recorded manually, which is very time-consuming
