Abstract
The utility model discloses a hot runner mold. The hot runner mold comprises a front fixing plate, a hot runner plate, a cavity plate and a cavity insert, which are successively arranged from top to bottom, wherein an injection port is formed in the front fixing plate; a first splitter plate and a second splitter plate are arranged in the hot runner plate; hot runners are arranged in the first splitter plate and the second splitter plate; the top of each hot runner is connected with the injection port; the bottom of each hot runner is communicated with a die cavity in the cavity insert by a plurality of hot sprues. The sandwich-type splitter plates are adopted in the hot runner mold, i.e. the hot runners are simultaneously arranged in the first splitter plate and the second splitter plate, without adopting a drilling way. The pore size of the hot runners can be regulated according to actual products. The dead corner area in the hot runners is avoided by respectively processing the two splitter plates, thereby solving the yellowing problem generated by white light products with plastic frames.
Description
Technical field
The utility model relates to mould applications, particularly a kind of hot runner mould.
Background technology
Injection mold can be divided into and pass mould, blow mold, plastic casting mould, hot forming tool, hot pressing die (compression tool), injection molding etc. according to moulding process, and wherein injection molding can be divided into again two kinds of cold runner die, hot runner moulds with running gate system difference.Compared with traditional cold runner die, hot runner mould has the advantage such as economize in raw materials, enhance productivity.
As shown in Fig. 1～2, in current hot runner mould, hot flow path 10 is arranged in a monoblock type flow distribution plate, that is, only have by flow distribution plate is carried out to Drilling operation and could form hot flow path 10.And Drilling operation exists limitation, not only hot flow path 10 apertures are larger, and after processing, the dead angle area 20 of hot flow path 10 is too many, and dead angle area 20 easily causes light-duty white size frame product to produce yellow.
Utility model content
The utility model provides a kind of hot runner mould, the yellow problem producing to solve light-duty white size frame product.
For solving the problems of the technologies described above, the utility model provides a kind of hot runner mould, comprises successively front shoe, heat flux plates, caster and mother module core from top to bottom; Wherein, on described front shoe, be provided with injection hole, in described heat flux plates, be provided with the first flow distribution plate and the second flow distribution plate, in described the first flow distribution plate and the second flow distribution plate, be provided with hot flow path, the top of described hot flow path is connected with described injection hole, and the bottom of described hot flow path is communicated with the die cavity in mother module core by multiple hot mouths.
As preferably, described the first flow distribution plate is provided with some back-up blocks.
As preferably, affixed by screw between described the first flow distribution plate and the second flow distribution plate.
As preferably, the hot flow path in described the first flow distribution plate and the second flow distribution plate adopts the mode of digital control processing to form.
Compared with prior art, the utlity model has following advantage: adopt the flow distribution plate of sandwich-type, by jointly offering hot flow path in the first flow distribution plate and the second flow distribution plate, without adopting bore mode, the pore size of hot flow path can be according to actual product adjustment; Respectively two flow distribution plates are processed, avoided the generation of dead angle area in hot flow path, and then solved the yellow problem that light-duty white size frame product produces.
