The runner mechanism disclosed by the utility model reduces the dimension of the main runner below the sprue, and reduces the waste of raw materials.
Description
Technical field
The utility model relates to a kind of three plate moulds, is specifically related to a kind of for reducing the runner mechanism of three template die injection raw material wastes.
Background technology
In traditional runner design scheme, in order to guarantee that the injection pressure of sprue does not lose, the bottom of the corresponding sprue bushing of sprue is provided with disk well, although disk well has solved the problem of injection pressure loss, because disk well diameter is much larger than sprue diameter, the raw material that therefore need to inject at disk Jing Chu is more, when cooling because size causes more greatly cool time elongated, the cycle of formed product is elongated, has therefore directly caused the manufacturing cost of product to increase, the adverse consequences that the production cycle is long.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of runner mechanism, can reduce the manufacturing cost of product, the reduction production cycle.
For achieving the above object, the technical solution of the utility model is as follows: a kind of runner mechanism, for three template die glue-feeding systems, described three template dies comprise sprue bushing and the upper mounted plate setting gradually from top to bottom, stripper plate and front template, described front template is embedded with front cavity, described sprue bushing connects fixed plate and stripper plate successively, described front template is provided with runner mechanism, described runner mechanism comprises sprue and the runner being interconnected, wherein said sprue is horizontally placed on described front template and with the bottom of described sprue bushing and is communicated with, described sprue is provided with the slag well of rectangle, described slag well arranges over against the bottom of described sprue bushing, described runner is vertically placed through successively described front template and front cavity and is communicated with product die.
Preferably, described slag well protrudes towards the bottom direction of described sprue.
Preferably, the degree of depth of described slag well is identical with the described sprue degree of depth.
Preferably, the width of described slag well and the equal diameters of described sprue and match with the runner caliber of described runner.
Preferably, described runner is provided with at least one, and the injection point of the setting position of each runner and described product die matches.
Adopt the beneficial effect of above technical scheme to be: due to sprue is provided with to rectangle slag well over against the bottom of described sprue bushing, under the prerequisite that guarantees runner input size, not lose injection pressure; Rectangle slag well, because size is little a lot, has reduced raw-material waste simultaneously, reduces cool time simultaneously, has shortened the molding cycle of product, has reduced the manufacturing cost of product.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, in the runner mechanism design of three traditional template dies, in order to guarantee that the injection pressure of sprue 5 does not lose, the bottom of the corresponding sprue bushing 4 of sprue 5 is provided with disk well 10, although disk well 10 has solved the problem of injection pressure loss, but because disk well 10 diameters are much larger than sprue 5 diameters, the raw material that therefore need to inject at disk Jing10Chu is more, when cooling because size causes more greatly cool time elongated, the cycle of formed product is elongated, therefore directly caused the manufacturing cost of product to increase, the adverse consequences that the production cycle is long
The utility model provides a kind of runner mechanism, and as shown in Figure 3-4, three template dies are disposed with upper mounted plate 3, stripper plate 2 and front template 1 from top to bottom, and front template 1 is embedded with front cavity 6; Sprue bushing 4 connects successively upper mounted plate 3 and is connected with stripper plate 2 and with front template 1.
Front template 1 is provided with runner mechanism, runner mechanism comprises sprue 5 and the runner 7 being interconnected, wherein sprue 5 is horizontally placed on front template 1 and with the bottom of sprue bushing 4 and is communicated with, and runner 7 is vertically placed through successively front template 1 and front cavity 6 and is communicated with product die 8.
Sprue 5 is provided with the slag well 9 of rectangle, and slag well 9 arranges over against the bottom of sprue bushing 4, and for fear of the pressure loss, the degree of depth of slag well 9 is identical with the degree of depth of sprue 5; The diameter of the width of slag well 9 and sprue 5 is identical and match with the runner caliber of runner 7.
Runner 7 is at least provided with two, be communicated with sprue 5 respectively, raw material pours into from sprue bushing 4, during slag well 9 by sprue bushing 4 bottoms, because slag well 9 hierarchy structures all match with sprue, therefore there is no injection pressure loss, thereby guaranteed the quality of product injection moulding, simultaneously, because slag well 9 sizes are less, compare the disk well 10 before not improving, shortened cool time, and the cycle of formed product also can shorten.
Adopt the beneficial effect of above technical scheme to be: due to sprue is provided with to rectangle slag well over against the bottom of sprue bushing, under the prerequisite that guarantees runner input size, not lose injection pressure; Rectangle slag well, because size is little a lot, has reduced raw-material waste simultaneously, reduces cool time simultaneously, has shortened the molding cycle of product, has reduced the manufacturing cost of product
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
