Abstract
The utility model discloses a glue feeding mechanism for processing a central processing unit (CPU) socket, which comprises a main flow channel, a bypass flow channel and gates arranged on the bypass flow channel and is characterized in that the bypass flow channel is in a U-shaped structure, the main flow channel is arranged below the middle of the bypass flow channel, and a plurality of gates are arranged on the inner wall of the bypass flow channel symmetrically and evenly. Under the smaller pressure of an injection machine, a cavity of a mould is easily to be filled by the glue feeding mechanism for processing the CPU socket, simultaneously, the shrinkage rate of products is more even, and the product deformation can be better controlled.
Description
Technical field
The utility model relates to technical field of mold, is specifically related to a kind of gluing mechanism that advances that is used for CPU socket processing.
Background technology
The socket of CPU is a kind of plastic cement products, as shown in Figure 1, by plastic mould injection moulding, is characterized in: (1) intermediate throughholes is very many, and total thousands of holes are like cellular; (2) product approaches greatly, and thickness is 1.15mm only; (3) flatness of entire product requires very high.
In the socket process of injection molding of CPU, one side traditional to advance the glue mode be the glue that advances from product, totally 2 cast gates, as shown in Figures 2 and 3.Wherein, the cross section of cast gate as shown in Figure 4.The gluing mechanism that advances like this needs very big injection pressure just can fill out to be filled to end, and shrinkage factor is very inhomogeneous throughout simultaneously, thereby causes the product distortion very big, and flatness requires to reach qualified at all, causes mould to use.
Summary of the invention
The technical problems to be solved in the utility model is: be directed to the deficiencies in the prior art, a kind of gluing mechanism that advances that is used for CPU socket processing is provided, this is used for gluing mechanism can be filled full mould at an easy rate under the pressure of less relatively injection machine the die cavity that advances of CPU socket processing, simultaneously, make that the shrinkage factor of product is more even, the product distortion can be well controlled.
To achieve the above object of the invention, the technical scheme that the utility model adopted is: a kind of gluing mechanism that advances that is used for CPU socket processing is provided, comprises sprue, runner and be arranged on cast gate on the runner; It is characterized in that: described runner is U font structure, and sprue is arranged on the lower position at the middle part of runner; Be distributed with some cast gates symmetrically on the described runner madial wall.
According to the gluing mechanism that advances that is used for CPU socket processing provided by the utility model, it is characterized in that: evenly be provided with 4 cast gates on the madial wall of the described runner of each side.
According to the gluing mechanism that advances that is used for CPU socket processing provided by the utility model, it is characterized in that: described cast gate is divided into two sections, with adjacent one section the internal diameter of product less than with the bore of adjacent another section of runner.
In sum, this practical gluing mechanism that advances that is used for CPU socket processing that provides has following advantage:
1, changed by the runner that adopts U type structure and enter the glue position, changed to the both sides of product and advance glue, made that the shrinkage factor of product is more even, the product distortion can be well controlled;
2, change little cross-sectional area by cast gate suddenly in place near product, make the cast gate rear and front end have bigger pressure differential, can increase the shearing of melt effectively and produce bigger shear heat, thereby cause the apparent viscosity of melt to descend, the mobile enhancing helps mould and fills;
3, make under the pressure of less relatively injection machine, to fill the die cavity of expiring mould at an easy rate that by increasing cast gate quantity simultaneously, make that also the shrinkage factor of product is more even, the product distortion can be well controlled.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done and to be described in detail:
Shown in Fig. 5-7, this gluing mechanism that advances that is used for CPU socket processing comprises sprue 1, runner 2 and is arranged on cast gate 3 on the runner 2; It is characterized in that: described runner 2 is U font structure, and sprue 1 is arranged on the lower position at the middle part of runner 2; Be distributed with some cast gates 3 symmetrically on described runner 2 madial walls.Evenly be provided with 4 cast gates 3 on the madial wall of the described runner 2 of each side.Described cast gate 3 is divided into two sections, with adjacent one section the internal diameter of product less than with the bore of adjacent another section of runner.
The utility model is not limited to above-mentioned example, in claims of the present utility model institute restricted portion, and various distortion that those skilled in the art can make without creative work or revise the protection that all is subjected to this patent.
