Embodiment Construction
[0016] The balanced casting device for the laminated die of the present invention will be further described below with reference to the accompanying drawings.
[0017] like figure 1 As shown in the figure, taking the laminated mold balanced casting device of double-layer cavity as an example, the present invention includes an intermediate plate 1, a first-level distribution plate 13, a second-level distribution plate, and a third-level distribution plate. The left and right sides of the intermediate plate 1 The first punch and the second punch are respectively the first punch and the second punch. The first-stage shunt plate 13 is fixed on the first punch above the middle plate 1, and the total glue inlet 10 is fixedly installed on the left side of the first punch. The glue port 10 is connected to the first-stage manifold 13 through the main channel hot nozzle 12; the end of the first-stage manifold 13 is provided with a three-pass flow channel 14, and the three-pass flow chan...

The invention discloses a balanced pouring device of a laminated mold, belonging to the field of injection molds and aiming at solving the problem that the quality of a poured product is influenced by difference of temperatures, speeds and pressures of material flows of all glue injection holes of a laminated mold. According to the balanced pouring device of the laminated mold, a material flow enters a master glue inlet through a machine tool nozzle, enters a primary splitting plate through a main runner hot nozzle, then is split to enter a secondary splitting plate A and a secondary splitting plate B through a first splitting hot nozzle and a second splitting hot nozzle respectively, then is split to flow into a third splitting plate A, a third splitting plate B, a third splitting plate C and a third splitting plate D respectively, and finally enters a cavity through all glue injection hot nozzles and all glue injection holes. As the lengths and the structures of material flowing runners from the machine tool nozzle to all the glue injection holes are the same, the temperatures and the pressures are the same at all the glue injection holes, so that the balanced pouring effect can be achieved and the quality of the poured product is improved.
Description
technical field [0001] The invention relates to an injection mold, in particular to a balanced pouring device for a stacked mold. Background technique [0002] Laminated mold technology is a high-efficiency mold technology. The main principle is to stack two or more cavities in a pair of molds to reduce clamping pressure and mold dimensions and improve production efficiency. The laminated mold can form multiple products at the same time, and the cavities of the multiple products are distributed on more than two layers and arranged in an overlapping manner. Therefore, compared with the ordinary injection mold, the laminated mold greatly improves the production efficiency. and equipment utilization, and reduce costs. [0003] For the existing lamination die, the material flow enters the main channel from the nozzle of the machine tool, and then enters each plastic injection port through the branch channel. , speed and pressure are not completely consistent, this difference a...
