Inclined ejection pouring structure with double layers of pouring gates

Abstract

The invention discloses an inclined ejection pouring structure with double layers of pouring gates. A sub-runner, a branch runner, a first pouring gate and a second pouring gate are arranged on an inclined ejection head of the structure, and the first pouring gate and the second pouring gate are arranged at different heights of the inclined ejection head. The first end of the sub-runner is connected with a main runner of a mold, and the second end of the sub-runner is connected with the first pouring gate. The first end of the branch runner communicates with the middle of the sub-runner, the second end of the branch runner is connected with the second pouring gate, and a first water transfer opening adjusting switch and a second water transfer opening adjusting switch are arranged on the inclined ejection head. The structure has the beneficial effects that the mold structure is simplified, and the pouring requirements of different heights can be met; control over pouring of the two pouring gates can be achieved, and simultaneous production of two products or production of only one product is achieved; the waste and pressure drop of drainage opening materials on the sub-runner and the branch runner are reduced; defective problems of products can be reduced, and the inclined ejection head can also play a role in ejection, so that ejection of the products is more balanced.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an inclined top pouring structure with double-layer gates. Background technique [0002] The gate can be understood as the last "gate" for molten plastic to enter the cavity through the gating system, and it is the feed channel connecting the runner and the cavity. It has two functions. First, it controls the flow of plastic melt into the cavity; second, when the injection pressure is removed, it blocks the cavity so that the uncooled and solidified plastic in the cavity will not flow back. [0003] The pouring structure of existing molds usually only has one gate, but in fact, in the design process of the mold, there will be situations where multiple products need to be molded in the height direction of the mold (ie, the direction of mold release), and a single gate The pouring structure of the mouth cannot meet the pouring requirements.
