Abstract
The utility model relates to a device for separation of a product assembly shell. The device for separation of the product assembly shell comprises a fixed mould (1), a product (2) and a moving mould (3) and adapting screw holes (4). The fixed mould (1) is fixedly disposed on the moving mould (3). Mould joint between the fixed mould (1) and the moving mould (3) is an arc surface. By the use of the device for separation of the product assembly shell, delivery quality of the product can be guaranteed, and production efficiency is improved.
Description
Technical field
The utility model belongs to technical field of mold, particularly relate to a kind of prevent the Product Assembly shell from device.
Background technology
A polypropylene (PP plastics) lower cover, see Fig. 1, buckling deformation appears in the process of injection mo(u)lding easily, when assembling with loam cake, when on the die joint shown in Figure 1 with two screw locking products after, the flatness of product does not still reach requirement, shell between product and the loam cake is apparent in view from phenomenon, shell from the maximal clearance reach 0.86 millimeter, and the tolerance of standard is only ± 0.2 millimeter, out-of-size requires 0.46 millimeter, causes the shipment fraction defective to surpass 58.34%.
The utility model content
Technical problem to be solved in the utility model provide a kind of prevent the Product Assembly shell from device, can guarantee the shipment quality of product.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of prevent the Product Assembly shell from device, comprise cover half, product, dynamic model, the screw hole, described cover half is mounted on the dynamic model, and the die joint between the fixed half and moving half is a cambered surface.
In the die cavity between the described fixed half and moving half product is installed.
There is the screw hole of two symmetries the corresponding product position in the described dynamic model.
Beneficial effect
The utility model can guarantee the shipment quality of product, enhances productivity.
Description of drawings
Fig. 1 is the original mould front view.
Fig. 2 is the utility model front view.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 2, a kind of prevent the Product Assembly shell from device, comprise cover half 1, product 2, dynamic model 3, screw hole 4, described cover half 1 is mounted on dynamic model 3, and the die joint between cover half 1 and the dynamic model 3 is a cambered surface.
In the die cavity between described cover half 1 and the dynamic model 3 product 2 is installed.
There is the screw hole 4 of two symmetries described dynamic model 3 interior corresponding products 2 positions.
New Design of Dies adopts pre-deformation device, and be about to die joint (PL) and be designed to arc, the opposite direction of this arc and product 2 buckling deformations, radian is consistent.So, product 2 is after injection mo(u)lding, and the buckling deformation meeting of generation almost pulls into a horizontal plane with die joint (PL) from arc.Through revising die device, the buckling deformation amount of product 2 has guaranteed that in 0.32 millimeter, the fraction defective of shipment also has been reduced to 10.2%.
Claims (3)
- One kind prevent the Product Assembly shell from device, comprise cover half (1), product (2), dynamic model (3), screw hole (4) is characterized in that: described cover half (1) is mounted on the dynamic model (3), and the die joint between cover half (1) and the dynamic model (3) is a cambered surface.
- According to claim 1 a kind of prevent the Product Assembly shell from device, it is characterized in that: in the die cavity between described cover half (1) and the dynamic model (3) product (2) is installed.
- According to claim 1 a kind of prevent the Product Assembly shell from device, it is characterized in that: there is the screw hole (4) of two symmetries the interior corresponding product of described dynamic model (3) (2) position.
