Abstract

The invention relates to a method for designing a six-surface-identical hollow cube product mold, wherein a vertical parallel plane and a vertical plane divide six-surface-identical hollow cube products into 1/8 solid products which are symmetrical by taking the central point of the six-surface-identical hollow cube products as the center, an injection mold is designed according to 1/8 solid products, and eight products produced by adopting the injection mold are assembled and bonded according to a cube mode to replace the six-surface-identical hollow cube products produced by integral injection molding; through this technical scheme, make six the same cavity square products need not consider mold core draw-out device and technology in the mould again, can directly adopt solid core product to mould plastics, and the product of adopting injection mold production to assemble the bonding according to the square mode with eight after moulding plastics in order to replace the whole six the same cavity square products of moulding plastics production, greatly reduced the complexity of mould and technology, effectual reduction manufacturing cost.

Description

Design method of hollow cube product mold with six identical surfaces

Technical Field

The invention relates to a design method of a product mold, in particular to a design method of a hollow cube product mold with six identical surfaces.

Background

In the process of manufacturing a hollow square product, the mold generally adopts an open-close mold, the left mold and the right mold are in butt joint production, some cube shells are often required to be manufactured in the production and manufacturing of electronic products, holes are formed in the surfaces of the cube shells to ensure that subsequent electronic boards, sensors and the like can be placed in the cubes, in the process of manufacturing the cubes, the left mold and the right mold are adopted to separately take out injection molding parts, meanwhile, an injection molding inner core is required to be arranged in the injection molding process, and meanwhile, an extraction device and a process of the inner core are required to be arranged.

Disclosure of Invention

In view of the above, the main object of the present invention is to provide a method for designing a mold for a hollow cube product having six identical faces, by which an original mold requiring an inner core is changed into a solid workpiece mold requiring no inner core, thereby greatly simplifying the production process, reducing the mold cost, and effectively improving the production efficiency.

In order to achieve the purpose, the technical scheme of the invention is realized as follows: the utility model provides a six same cavity square product mold design method, set up two mutual orthogonality with six same cavity square product front plane and central point as the benchmark and pass through the vertical parallel plane and the vertical plane of six same cavity square product central point to vertical parallel plane and vertical plane divide into 1/8 solid core products of central symmetry with the central point of six same cavity square product with vertical parallel plane and vertical plane, and design injection mold according to 1/8 solid core products, assemble the bonding according to the square mode with eight products that adopt injection mold to produce in order to replace the six same cavity square product of whole injection molding production.

The beneficial effect after adopting above-mentioned technical scheme is: the utility model provides a six same hollow cube product mold design method, through this technical scheme, divide into the same 1/8 solid core products of shape with six same hollow cube products, make six same hollow cube products need not consider mold core draw-out device and technology in the mould again, can directly adopt solid core product to mould plastics, the eight products that adopt injection mold production are assembled according to the cube mode and are bonded in order to replace the same hollow cube product of six of whole injection molding production after moulding plastics, greatly reduced the complexity of mould and technology, effectual manufacturing cost that has reduced.

Detailed Description

Specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 1-6, the method for designing a six-sided identical hollow cube product mold according to the present invention arranges two vertical parallel planes 4 and vertical planes 5 orthogonal to each other and passing through a center point 2 of the six-sided identical hollow cube product 1 on the basis of a front plane 3 and the center point 2 of the six-sided identical hollow cube product 1, divides the six-sided identical hollow cube product 1 into 1/8 solid products 6 symmetrical about the center point 2 of the six-sided identical hollow cube product 1 by the vertical parallel planes 4 and the vertical planes 5, designs an injection mold according to 1/8 solid products 1, and assembles and bonds eight products produced by the injection mold in a cube manner to replace the six-sided identical hollow cube product 1 produced by integral injection molding.

The six-face same hollow cube product mold design method can also be applied to axisymmetric rectangular hollow products, and at the moment, two different 1/8 solid products 6 appear, so that two different 1/8 solid products 6 need to be respectively subjected to mold opening and combined and bonded according to the integral shape.

The hollow shape in six surfaces of the hollow cube product 1 with the same six surfaces can also be other shapes which accord with rotation symmetry.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention.
