Embodiment 2

[0050] The second embodiment of the present invention also proposes a mold, including the above-mentioned template assembly.

[0051] To sum up, the mold in the above-mentioned embodiment of the present invention, by arranging the waterway structure on the second circumference, and the second circumference is set concentrically with the first circle where the inlet hole is located, ensures that the distance between each hole and the water is transported. All are equal, the number of holes is not limited, and multi-holes can be evenly heated or cooled; in addition, the waterway structure of this application adopts a double-layer waterway design, and the upper and lower waterways are separated by water barriers, so that the upper and lower waterways are separated by a partition The water sheet can perform heat exchange to achieve the purpose of temperature compensation, with good heating or cooling effect and good overall temperature control.

Abstract

The invention provides a mold plate assembly and a mold. The mold plate assembly comprises a mold plate, a pressing plate connected with the mold plate and a plurality of water-stop sheets, a plurality of waterway structures are formed between the mold plate and the pressing plate, the mold plate is provided with a plurality of mold core insert holes, the plurality of mold core insert holes are arranged on a first circumference, and the plurality of waterway structures are arranged on a second circumference; and the first circumference and the second circumference are concentrically arranged,and a water stop sheet is arranged in each waterway structure and divides the corresponding waterway structure into an upper-layer waterway and a lower-layer waterway which communicate with each other. According to the mold plate assembly, the distances between inserts in all holes and water can be ensured to be equal, the number of holes is not limited, and multi-hole uniform heating or cooling can be carried out; and besides, the waterway structures adopt double-layer waterway design, and the upper-layer waterways and the lower-layer waterways are separated by water-stop sheets, so that theupper-layer waterways and the lower-layer waterways can exchange heat through the water-stop sheets, the purpose of temperature compensation is achieved, the heating or cooling effect is good, and theoverall temperature control performance is good.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a template component and a mold. Background technique [0002] The mold waterway refers to the penetrating hole machined in the plastic mold mold base and mold core, which circulates in the mold waterway through a certain medium (such as water, oil) to control the temperature of the mold. Well control the cooling and shrinkage of plastic products in the mold, so as to meet the requirements of controlling product size and surface. [0003] Among existing technologies, such as figure 1 As shown, the currently used mold waterway is a well-shaped waterway, and the well-shaped waterway has the following defects: [0004] (1) Limit the number of cavities. When the number of mold cavities is large, the heating or cooling effect of A1~A8 sub-holes is worse. For example, A1 inlet hole, the distance from the X direction to the water delivery is d2, and the distance from the Y direction to...
