Description

Technical Field

[0001] The present invention relates to the technical field of soft material forming technology, and more specifically, to a vertical cutting composite process method for forming air passages and ventilation holes inside a soft material, and a wind-controlled temperature mattress formed by the process method. Background Art

[0002] At present, the principle of the existing air temperature control mattress is to set an air supply channel inside the air temperature control mattress, and provide warm air through the air supply host to achieve air temperature control;

[0003] The existing wind-controlled temperature mattress includes an upper pad, a lower pad and an air supply main unit. A plurality of air supply channel grooves are provided under the upper pad, and a plurality of air holes penetrating the surface of the upper pad are provided on the air supply channel grooves. The lower side of the upper pad is covered on the upper side of the lower pad, so that an air supply channel is formed between the air supply channel grooves and the lower pad. A portion of the warm air blown out by the air supply main unit penetrates the pad body through the upper pad and the lower pad through the air supply channel, and most of it flows out of the pad body from the air holes, thereby effectively realizing the functions of heat transfer and circulation as well as dehumidification and drying of the pad body.

[0004] The air passages and ventilation holes inside the existing soft materials (wind-controlled temperature mattresses) are mainly formed through mold molding. The process is to inject liquid raw materials into the mold and foam them. The molding time is 6-7 minutes. After molding, an upper pad with air supply channel grooves and air holes will be directly formed. However, in order to meet the demolding requirements, there are requirements on the density of the raw materials (otherwise it is difficult to demold), and it is impossible to mold the upper pad of the required density according to the demand; on the other hand, the cost of mold molding is relatively high.

[0005] For example, Chinese patent document: CN111791428A, publication date: 2020.10.20, discloses a method for forming a mold for a magnetic therapy mattress, which method includes the following steps: first, prepare the mold, first make the specifications of the mold according to the size specifications and area of ​​the magnetic therapy sheet, and then determine the membrane flow, temperature, mold positioning and quality inspection of the mold cavity, and then conduct a trial mold and record it. After the test film product is qualified, the prepared magnetic therapy mattress mold is obtained; the method for forming the mold of the magnetic therapy mattress described in the present invention, through the steps of preparing the mold, preparing the mattress raw materials, mixed foaming, injection molding and curing, the prepared magnetic therapy mattress can be formed in one step through the mold, and the magnet and the foam become one during injection molding, so that the magnet will not move during long-term use, so that the service life of the prepared magnetic therapy mattress is increased, the operation is simple, and it is easy to use, and it has good prospects for use.

[0006] However, in this technical solution, in order to smoothly demold the formed mattress, a relatively high density of the raw materials is required; for example, 45 parts of natural latex, 12 parts of toluene diisocyanate, 30 parts of polyolefin, 1.5 parts of foaming agent, 3 parts of carbon fiber, 1 part of foaming agent, 0.5 parts of catalyst, 1 part of surfactant, and 1.5 parts of graphene are required in the article; it is impossible to form soft materials of the required density according to demand.
