Abstract
The utility model discloses a kind of leaf spring back bush injection moulding particular manufacturing craft, comprise patrix (1), middle mould (2) and counterdie (3); Described patrix (1) is provided with the injection moulding sprue (1a) and injection hole (1b) that communicate with each other; Described middle mould (2) is provided with the die cavity (2a) holding leaf spring back bush (5); Described die cavity (2a) is corresponding with described injection hole (1b) to be arranged; Described counterdie (3) is provided with mold insert (4); The quantity of described die cavity (2a) and injection hole (1b) is 4n, and n is natural number; Every four described injection holes (1b) form an injection molding unit (100); It is first " X " shape that the injection hole (1b) of each described injection molding unit (100) is communicated with.The utility model the rubber of fusing can be made to enter temperature in die cavity and weight basically identical, thus improve the stability of injection moulding quality.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of for the mould of leaf spring back bush injection moulding.
Background technology
The back bush of leaf springs of car comprises purchasing ore and inner frame, is injected with rubber between purchasing ore and inner frame.In the process of rubber batch injection moulding, there is difference due to the temperature of rubber in the lining of distance sprue gate diverse location, even the therefore leaf spring back bush of same batch, product quality also exists larger difference.
Therefore those skilled in the art are devoted to exploitation and a kind ofly make the particular manufacturing craft that leaf spring back bush injection molding quality is more stable.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide and a kind ofly makes the particular manufacturing craft that leaf spring back bush injection molding quality is more stable.
For achieving the above object, the utility model provides a kind of leaf spring back bush injection moulding particular manufacturing craft, comprises patrix, middle mould and counterdie; Described patrix is provided with the injection moulding sprue and injection hole that communicate with each other; Described middle mould is provided with the die cavity holding leaf spring back bush; Described die cavity is corresponding with described injection hole to be arranged; Described counterdie is provided with mold insert; The quantity of described die cavity and injection hole is 4n, and n is natural number; Every four described injection holes form an injection molding unit; It is first " X " shape that the injection hole of each described injection molding unit is communicated with.
It is second " X " shape that adjacent four described injection molding unit are communicated with.
Described injection moulding sprue is communicated with the center of described second " X " shape.
The quantity of described die cavity and injection hole is 16.
The beneficial effects of the utility model are: the utility model the rubber of fusing can be made to enter temperature in die cavity and weight basically identical, thus improve the stability of injection moulding quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one detailed description of the invention.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Fig. 3 is the plan structure schematic diagram removing patrix in the utility model one detailed description of the invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, Figure 2 and Figure 3, a kind of leaf spring back bush injection moulding particular manufacturing craft, comprises patrix 1, middle mould 2 and counterdie 3.Patrix 1 is provided with the injection moulding sprue 1a and injection hole 1b that communicate with each other, middle mould 2 is provided with the die cavity 2a holding leaf spring back bush 5, die cavity 2a is corresponding with injection hole 1b to be arranged.Counterdie 3 is provided with mold insert 4.The quantity of die cavity 2a and injection hole 1b is 16.
Every four injection hole 1b form an injection molding unit 100, and it is first " X " shape that the injection hole 1b of each injection molding unit 100 is communicated with, and it is second " X " shape that four adjacent injection molding unit 100 are communicated with.Injection moulding sprue 1a is communicated with the center of second " X " shape.
In other detailed description of the invention, the quantity of die cavity 2a and injection hole 1b also can be other 4n values beyond 16, and n is natural number, to reach substantially identical technique effect.
During injection moulding, mould is placed on backing plate 6, starts fluidisation machine, make the plastics of fusing enter injection moulding sprue 1a, then flow through injection hole 1b and enter in die cavity 2a.Due to the appropriate design to injection molding channel, the rubber of fusing therefore can be made to enter temperature in die cavity and weight basically identical, thus improve the stability of injection moulding quality.During die sinking, patrix separates with middle mould, under the effect of fluidisation Oil cylinder, in mould eject, realize product stripping.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
