Abstract

The invention discloses a multi-cavity small-product small-nozzle hot runner. The multi-cavity small-product small-nozzle hot runner comprises a sprue, a bridging upper plate, a bridging lower plate,a runner upper plate, a runner lower plate, nozzle cores and a front mold core, wherein the runner upper plate is provided with a semicircular runner, the runner lower plate is provided with a semicircular runner, and after the runner upper plate and the runner lower plate are locked through screws, the two semicircular runners form a whole runner; the upper bridging plate is provided with a semicircular runner, the lower bridging plate is provided with a semicircular runner, and after the upper bridging plate and the lower bridging plate are locked through screws, the two semicircular runnersform a whole runner; and the nozzle cores are in communication with a product cavity through the runner of the front mold core. The multi-cavity small-product small-nozzle hot runner has the beneficial effects that heating wires are arranged on the bridging plates and the runner plates, and the nozzle cores are arranged on the runner plates, so that the problem of waste of water gap material at amain runner can be solved; and the nozzle cores are arranged to pass through the runner of the front mold core to pour a product so that the problems of glue feeding of appearance products and the waste of the water gap material in the cavity can be solved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a hot runner with small nozzles for multi-cavity small products. Background technique [0002] In injection molding production, the treatment of nozzle material is a big problem. If recycled materials are added to the nozzle, after many cycles, there will be a small part of recycled materials in each product, but this is very small. A part of recycled materials can greatly affect the performance of the product, especially for a small product mold, the runner material accounts for a large proportion of the entire injection plastic, and some can account for 80%, that is, 80% of the weight is 20% of the nozzle. % of the weight of the product, this nozzle part is going to waste. [0003] Some products cannot be directly injected with nozzle cores like ordinary hot runners, because the front cores of such products are all exterior surfaces, and it is not allowed to set glue points, wh...
