Abstract
The invention discloses a kind of heat pressing process of the foamed products of shape structure with holes, include the following steps: that (1) produces through-hole by Milling Process on the corresponding position of foam material；(2) the hole plug for making respective diameters is mounted on the upper die tool of hot pressing die and pushes between mold, and hole plug is connected by spring with upper die tool；(3) foam material is placed on upper die tool and pushed between mold, hole plug is inserted in the through-hole that foam material is produced；(4) mold is heated to determined temperature, keeps upper die tool and pushes mold pressing pressure and keep pressing-in temp, meanwhile, hole plug carries out heat effect to the foam material at the hole wall of through-hole with temperature identical with pressing-in temp.The invention has the beneficial effects that: the problems such as increasing the Porous Characteristic of neat appearance for the product of high resiliency or flexible material, avoiding the destruction surface of following process.
Description
Technical field
The invention belongs to foamed products hot-pressing technique fields, and in particular to a kind of hot pressing of the foamed products of shape structure with holes
Technique and its hot-press equipment.
Background technique
It is existing by mold cold pressing or hot-forming product, can not directly make similar aperture or through-hole, Zhi Nengtong
Later continue machining, or expand aperture and suppressed by mold cores can make using processing technologys such as milling drillings after compacting
At interiors of products powdered material, differs too big with appearance material appearance, unsightly, does not bear dirty, and since material is flexible,
The aperture equidimension deformation drilled out is serious, and size is different；The hole bigger for diameter, such as diameter > 5cm through-hole, then do not have
There is the cutter of suitable major diameter to process.It can only be suppressed by the type core of mold can exist but due to the elasticity of material
Xing Xin corner generates brittleness, and the defects of Density inhomogeneity or adhesion, the inner surface that when depanning will also result in hole draws bad the problems such as.
Therefore, new technology is needed to improve the deficiencies in the prior art.
Summary of the invention
Goal of the invention: the purpose of the present invention is the shortcomings that overcoming above-mentioned technology, it is good to provide a kind of hot pressing effect, hot pressing
Shaped article quality is high, and the heat pressing process of the foamed products of the unrestricted shape structure with holes in aperture for the product processed and
Its hot-press equipment.
Technical solution: a kind of heat pressing process of the foam material of shape structure with holes includes the following steps:
(1) through-hole is produced by Milling Process on the corresponding position of foam material；
(2) the hole plug for making respective diameters is mounted on the upper die tool of hot pressing die and pushes between mold, and hole plug passes through
Spring is connected with upper die tool, keeps verticality and screen resilience；
(3) foam material is placed on upper die tool and pushed between mold, hole plug is inserted in the through-hole that foam material is produced
In；
(4) mold is heated to determined temperature, keeps upper die tool and pushes mold pressing pressure and keep pressing-in temp, upper die
Foam material is pressed into corresponding shape with pushing mold by tool, meanwhile, hole plug is with temperature identical with pressing-in temp to through-hole
Hole wall at foam material carry out heat effect.
A kind of hot-press equipment for realizing above-mentioned hot-press method, including press upper plate and press lower plate；The press upper plate
Lower part has equipped with upper die；The press lower plate top, which is equipped with, pushes mold；It is set in the middle part of the upper die tool lower surface
There is upper forming tank；The middle part of the pushing mould upper surface is equipped with lower forming tank；In the upper forming tank of the upper die tool
Equipped with groove；Hole plug is connected with by spring in the groove.
The invention has the beneficial effects that: the core-pulling die technique of Shooting Technique is introduced into foamed products by the present invention
In the hole core design of mold, the product for high resiliency or flexible material increases the features such as the hole of neat appearance, after avoiding
The problems such as destruction surface of continuous processing, thus the aperture for the product for expanding the scope of design of foam product, and processing not by
Limitation has product aesthetics height, strong flexibility, the beneficial effect improved production efficiency and product quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of hot-press equipment of the invention.
1 is press upper plate in figure, and 2 be groove, and 3 have for upper die, and 4 be spring, and 5 be hole plug, and 6 is push mold, and 7 are
Press lower plate, 8 be upper forming tank, and 9 be lower forming tank.
Specific embodiment
Technical scheme is described further below.
