Abstract
The utility model discloses the flow passage structure of injection moulding, die casting, it comprises multipair centrifuge tube, sprue and runner, sprue is arranged at the center of each runner, centrifuge tube is arranged at the end of runner, macromolecule melted material enters from sprue, enter each centrifuge tube through runner, the distance between sprue to each centrifuge tube is equal.The flow passage structure of injection moulding of the present utility model, die casting, the distance between sprue to each centrifuge tube is equal, the pressure suffered by each centrifuge tube, the time of charging, the macromolecule melted material entered, all will be unanimously or highly consistent, its product quality will improve greatly.
Description
Technical field
The utility model relates to the flow passage structure of a kind of injection moulding, die casting.
Background technology
PCR pipe in biomedicine experiment application tool, because it has the requirement of moment heating and cooling to sample in pipe, and the feature that quantity application is very many, so just have very high requirement to the PCR pipe of injection mo(u)lding to thin-walled and uniformity, but, in injection molding, generally adopt the runner as H type in Fig. 1 to arrange, as seen from Figure 1, A point enters macromolecule melted material for sprue, it arrives the time of B point and C point, pressure, doses can not be consistent, and then cause product 3 and product 4 also will have inconsistent feature, more be difficult to ensure that the thin-walled of card product 3 and 4 can reach, by that analogy, product 1 in this figure, 2, 3, 4, 5, 6, 7, 8 can not have the same thin-walled, good uniformity can not be had.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
The technical problems to be solved in the utility model is to provide the flow passage structure of a kind of injection moulding, die casting, makes injecting products uniformity good.
For solving the problems of the technologies described above, the flow passage structure of injection moulding of the present utility model, die casting, it comprises multipair centrifuge tube, sprue and runner, described sprue is arranged at the center of each runner, described centrifuge tube is arranged at the end of runner, macromolecule melted material enters from sprue, enters each centrifuge tube through runner, and the distance between described sprue to each centrifuge tube is equal.
Described centrifuge tube at least 3 is right.
The flow passage structure of injection moulding of the present utility model, die casting, the distance between sprue to each centrifuge tube is equal, the pressure suffered by each centrifuge tube, the time of charging, the macromolecule melted material entered, all will be unanimously or highly consistent, its product quality will improve greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Wherein: 1, centrifuge tube, 2, sprue, 3, runner.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection domain of the present utility model.
As shown in Figure 2, the flow passage structure of injection moulding of the present utility model, die casting, it comprises multipair centrifuge tube 1, sprue 2 and runner 3, sprue 2 is arranged at the center of each runner 3, centrifuge tube 1 is arranged at the end of runner 3, macromolecule melted material enters from sprue 2, enters each centrifuge tube 1 through runner, and the distance between sprue 2 to each centrifuge tube 1 is equal.
Above-mentioned centrifuge tube 1 at least 3 is right, and it is 4 right to be provided with in Fig. 2.Shown in Fig. 2, A point is the feed points of the macromolecule melted material of sprue 2, B, C, D, E, F, G, H, I point, be dispersed in the surrounding of A point, form a circle, the round such runner of Fig. 2 is adopted to arrange, the problem in Fig. 1 can be avoided undoubtedly, runner line segment AC, AD, AF, AH, AG, AI, AB, AE length is always consistent, its pressure suffered by product 1,2,3,4,5,6,7,8, the time of charging, the macromolecule melted material entered, all will be unanimously or highly consistent, therefore, its product quality will improve greatly.
Claims (2)
1. the flow passage structure of injection moulding, die casting, it is characterized in that: it comprises multipair centrifuge tube, sprue and runner, described sprue is arranged at the center of each runner, described centrifuge tube is arranged at the end of runner, macromolecule melted material enters from sprue, enter each centrifuge tube through runner, the distance between described sprue to each centrifuge tube is equal.
