Description

Technical Field

[0001] This utility model belongs to the field of mold processing technology, and in particular relates to the internal cutting structure of a graded ejector mold. Background Technology

[0002] Secondary ejection is an ejection technology developed in the mold manufacturing industry to solve the demolding needs of complex products. It reduces the force applied by the ejector pins through a staged ejection mechanism, avoiding defects such as product deformation and white edges. This structure is suitable for situations where the runner and gate are injected on the back of the product and the product needs to be automatically separated from the runner. It is commonly found in automotive grille products.

[0003] For example, Chinese patent CN203712999U discloses an in-mold cutting structure. The mold has an upper fixed plate, a female template, a male template, and a lower fixed plate arranged in sequence. The structure includes: an upper top plate, located between the male template and the lower fixed plate; a lower top plate, located between the male template and the lower fixed plate, and below the upper top plate; a push rod, passing through the lower fixed plate and abutting against the lower part of the lower top plate; a limiting post, in the mold-closed state, with one end abutting against the lower fixed plate, and when the push rod is not ejected, there is a first distance between the limiting post and the lower top plate, and a limiting ejector pin is provided below the limiting post; a first ejector pin, one end of which is fixed between the upper top plate and the lower top plate, and the other end has a cutter, and when the push rod is not ejected, the cutter is close to the area between the product and the runner.

[0004] This patent has the following problems: Existing technologies do not allow for automated gate reduction in molds, and require manual intervention during mold ejection, thus reducing production efficiency. Furthermore, they do not facilitate gate cutting during ejection, increasing labor costs associated with mold trimming. Therefore, we propose a staged ejection mold with an internal cutting structure. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a graded ejector die internal cutting structure, thereby improving mold production efficiency and reducing costs.

[0006] In view of this, the present invention provides a graded ejector mold internal cutting structure, including a gate inclined ejector sliding seat body, and further including: a gate inclined ejector sliding seat pad plate movably installed at the bottom of the gate inclined ejector sliding seat body, a straight ejector guide rod pad plate fixedly installed at the top of the movable end of the gate inclined ejector sliding seat body, a straight ejector guide rod body fixedly installed at the top of the straight ejector guide rod pad plate, a straight ejector body fixedly installed at the top of the movable end of the straight ejector guide rod body, and a product movably installed at the top of the straight ejector body.

[0007] Based on the above structure, the top of the gate sloping top sliding seat pad and the bottom of the movable end of the gate sloping top sliding seat body are fixedly installed. Then, the top of the movable end of the gate sloping top sliding seat body drives the straight ejector guide rod pad and the straight ejector guide rod body to adjust and move, which can automatically reduce the gate of the mold, thereby improving the efficiency of mold production. Then, the movable end of the straight ejector guide rod body drives the straight ejector body to move inside the product and cut off the product. This can cut off the gate in the mold during the ejection process, thereby reducing the labor cost of mold trimming.

[0008] Preferably, the outer side of the straight guide rod body is fitted with a guide rod anti-rotation cover plate, the inner side of the guide rod anti-rotation cover plate is fitted with a guide sleeve body, and the inner side of the guide sleeve body is fitted with a guide sleeve bushing.

[0009] Preferably, a gate inclined top guide rod is fixedly installed at the movable end inside the gate inclined top sliding seat body, and a first-stage push plate is fixedly installed on the outside of the gate inclined top sliding seat body.

[0010] Preferably, a gate inclined top body is fixedly installed on the top of the movable end of the gate inclined top guide rod, and a flow channel is fixedly installed on one side of the gate inclined top body.

[0011] Preferably, each of the first-stage push plates has a first-stage push plate slot through it, and both ends of the first-stage push plate slot have first-stage push plate threaded holes through it. A second-stage push plate is fixedly installed at the bottom of the first-stage push plate, and a nitrogen spring body is fixedly installed inside the first-stage push plate.

[0012] Preferably, the interior of each secondary push plate is provided with a secondary push plate slot, and both ends of the secondary push plate slot are provided with secondary push plate threaded holes.

Limit screws are threadedly installed on one side of the nitrogen spring cover plate body.

[0014] The beneficial effects of this utility model are: 1. This graded ejector mold internal cutting structure is fixedly installed through the top of the gate inclined ejector sliding seat pad and the bottom of the movable end of the gate inclined ejector sliding seat body. Then, the top of the movable end of the gate inclined ejector sliding seat body drives the straight ejector guide rod pad and the straight ejector guide rod body to adjust and move. This can automatically reduce the gate of the mold and eliminate the need for manual intervention when the mold is ejected, thereby improving the efficiency of mold production.

[0015] 2. This graded ejector die internal cutting structure, through the movable end of the straight ejector guide rod body, drives the straight ejector body inside the product to cut off the product during ejection.
