Embodiment 1

[0059] The embodiment of the present application discloses a one-shot injection mold. refer to figure 2 and image 3 , a one-time injection mold, including a fixed mold, a movable mold for fitting with the fixed mold, the fixed mold includes a fixed mold main body 2, a fixed template 21 fixed on the fixed mold main body 2, and the movable mold includes a movable mold main body 1 , the moving template 11 that is fixed on the moving mold main body 1. The fixed template 21 is provided with a mold groove 1 22, and the movable template 11 is provided with a mold groove 2 12. After the surfaces of the fixed template 21 and the fixed template 21 are attached, the mold groove 1 22 and the mold groove 2 12 are combined to form a mold cavity. The main body 2 is provided with a pouring structure 3 for pouring glue into the cavity. The injection molding machine can inject glue into the cavity through the pouring structure 3 to complete the molding of the workpiece.

Embodiment 2

[0076] The difference between this embodiment and embodiment 1 is: refer to Figure 8 The ejector rod 241 located in the installation blind hole 1 23 is provided with a rotating end block 246, an air pressure channel 247, and an air pressure groove 248. The ejector rod 241 is away from the end of the blind hole-23 bottom wall and is rotatably connected. The rotating shaft of the rotating end block 246 is coaxial with the axis of the ejector rod 241. The air pressure groove 248 is positioned at the end of the ejector rod 241. The rotating end block 246 The air pressure groove 248 is closed towards the side wall of the ejector rod 241. The length direction of the air pressure channel 247 is along the length direction of the ejector rod 241. One end of the air pressure channel 247 is connected to the bottom wall of the air pressure groove 248, and the other end is connected to the ejector rod. 241 faces the sidewall of the vent hole 25 to communicate with the vent hole 25 .

Abstract

The application relates to an ice-making box injection molding process and a primary injection mold and a secondary injection mold thereof. The ice-making box injection molding process comprises a movable mold and a fixed mold, wherein the fixed mold is provided with a first mold groove, the movable mold is provided with a second mold groove, a pouring structure is arranged in the fixed mold, a first mounting blind hole and an ejection piece are arranged in the first mold groove, a vent hole is formed in the bottom wall of the first mounting blind hole, and the ejection piece comprises an ejection rod and a mounting sleeve. The ejector rod is provided with a reset spring, the movable mold is slidably provided with an ejector plate, the ejector plate is fixedly provided with an ejector pin, a cooling water channel is formed in the fixed mold, the pouring structure comprises a liquid inlet part and a liquid outlet pipeline, the liquid outlet pipeline is provided with a flow dividing piece, a flow dividing channel is formed in the flow dividing part, and the ejector rod is provided with a rotating end block, an air pressure channel and an air pressure groove. By arranging the first mounting blind hole, the ejection piece and the vent hole, the ejection piece can separate the product from the first mold groove in the fixed mold, so that the product is not easy to take out by the fixed mold when the fixed mold is separated from the movable mold; by arranging the reset spring, the ejection piece can be automatically reset conveniently; and by arranging the flow dividing piece, the quality of a product formed by the mold is better.

Description

technical field [0001] The present application relates to the technical field of injection molds, in particular to an injection molding process for an ice box and its primary injection mold and secondary injection mold. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. [0003] Usually, the injection mold is composed of a fixed mold and a movable 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 fixed mold and the movable mold are closed to form a cavity, and when the mold is opened, the fixed mold and the movable mold are separated to take out the plastic product. [0004] The refrigerator ice box is a container used to make ice cubes. The container has multiple ice trays for forming ic...
