Abstract
The utility model relates to a plastic injection mold offset cross type internal heating multi-gating hot runner, which comprises a hot runner plate, a heating rod in the hot runner plate, and a hot runner nozzle vertical to the hot runner plate, and is characterized in that: an offset cross type hot runner opening is arranged in the hot runner plate; a heating rod in offset cross connection with the heating rod in the hot runner plate is arranged in the hot runner nozzle; and the offset cross type hot runner opening is communicated with the runner. The plastic injection mold offset cross type internal heating multi-gating hot runner has the advantages that: the offset cross type multi-gating hot runner is adopted, so that the defect that full internal heating is difficult to realize in a traditional right-angle crossed type runner is overcome, the inner heating rod can be conveniently arranged in the nozzle, the offset cross type multi-gating hot runner enables a nozzle runner to realize internal heating manner without affecting injection of plastic melts when in use, the heating power is reduced, the heating effect is improved, the production quality of an injection plastic product is ensured, the service life of a heating element is prolonged, and the cost is reduced.
Description
(1) technical field:
The utility model relates to device in a kind of mould, many cast gates of heating hot flow path in the inclined to one side staggered form of particularly a kind of plastic injection mould.
(2) background technology:
Adopt the hot flow path running gate system in the plastic injection mould, make the plastics in the running gate system be in molten condition all the time.During the injection of plastic product, the pressure loss is little, and shaping speed is fast.Because no running gate system is coagulated material, realized no waste material processing, saved the operation of removing cast gate, can practice thrift human and material resources, reduce production costs.Traditional many cast gates hot flow path is as shown in Figure 1; The form of heating in hot runner manifold 1 adopts; Promptly in hot flow path, be provided with heating rod 2, because heating rod is installed in the middle body of runner, the plastic melt in the runner can stop heat to external diffusion; Therefore reduce thermal loss, improved the efficiency of heating surface.The hot-runner nozzle 3 vertical with hot runner manifold 1 is because its inner hot flow path is square crossing, so the heating rod 2 in the hot runner manifold 1 has hindered the setting of the heating rod nozzle place in, so the nozzle place have to use outer heating collar 4 to carry out heating outward.This mode of heating heat ecto-entad conduction, thermal loss is big, and the efficiency of heating surface is low, has only the power through strengthening outer heating collar to remedy, and thus, has increased energy consumption, has reduced the service life of heating collar.
(3) summary of the invention:
The purpose of the utility model is to design many cast gates of heating hot flow path in the inclined to one side staggered form of a kind of plastic injection mould; It has overcome the shortcoming that conventional orthogonal V shape hot flow path is difficult to all realize interior heating; Make in the nozzle and also interior heating rod can be set easily, guaranteed production injection of plastic Products Quality thus.
The technical scheme of the utility model: many cast gates of heating hot flow path in the inclined to one side staggered form of a kind of plastic injection mould; Comprise hot runner manifold, the heating rod in it and the hot-runner nozzle vertical with hot runner manifold; It is characterized in that having on the hot runner manifold inclined to one side staggered form hot-fluid road junction; Have in the hot-runner nozzle with hot runner manifold in the heating rod heating rod of setovering each other and intersecting, said inclined to one side staggered form hot-fluid road junction communicates with runner.
The inclined to one side staggered form hot-fluid road junction that has on the above-mentioned said hot runner manifold vertical with hot-runner nozzle can place the left avertence portion or the right avertence portion of hot-runner nozzle heating rod.
The diameter of heating rod in the amount of bias at the inclined to one side staggered form hot-fluid road junction that has on the above-mentioned said hot runner manifold vertical with hot-runner nozzle equals.
The runner transition portion of the inclined to one side staggered form hot-fluid road junction that the above-mentioned said hot runner manifold vertical with hot-runner nozzle has itself and hot-runner nozzle adopts to prevent to be detained the smooth curve of plastic melt.
The superiority of the utility model is: 1, adopt the mode of inclined to one side many cast gates of staggered form hot flow path, overcome the shortcoming of heating in conventional orthogonal V shape runner is difficult to realize all, make in the nozzle and also interior heating rod can be set easily; In the use; Partially many cast gates of staggered form hot flow path make nozzle flow channel when not influencing the injected plastic melt, realize in mode of heating, reduced heating power, improved heats; Guaranteed production injection of plastic Products Quality: 2, it is simple in structure, practical; When reducing heating power, prolonged the service life of heating element heater, reduced production cost.
