Foaming silica gel mold production equipment

Abstract

The invention relates to the field of silica gel mold production, in particular to foamed silica gel mold production equipment which comprises an upper mold cavity and a lower mold cavity, the lower mold cavity is installed at the bottom of the upper mold cavity, a protruding layer is arranged at the bottom of the upper mold cavity, a concave layer matched with the protruding layer is formed in the upper end face of the lower mold cavity, and convex cambered surfaces matched with the concave layer are symmetrically arranged on the left side and the right side of the concave layer. According to the invention, a sealing mode that the convex cambered surface is embedded into the concave cambered surface is adopted, and compared with a traditional mode that the concave layer and the convex layer are attached for edge sealing, the structure contact is less, the pressure is more concentrated, and the edge sealing effect is better.

Description

Technical Field

[0001] The invention relates to the field of silicone mold production, and in particular to a foaming silicone mold production device. Background Art

[0002] Bra cups are important daily necessities for women. The bra cups on the market are generally made of sponges. However, the main raw material of sponges, TDI (toluene diisocyanate), is a toxic chemical. Long-term contact will harm health. And because the molecular structure of sponges is unstable, it is very easy to turn yellow. And because sponges are not breathable, they are easy to hide dirt. In order to solve the above defects of sponge cups, many manufacturers in the industry try to use foamed silicone cups instead of sponge cups.

[0003] The existing mold for producing foamed silicone cups is to directly fit the upper mold cavity with the lower mold cavity to perform edge sealing, which has a large contact area and dispersed pressure, resulting in poor edge sealing effect. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a foamed silicone mold production equipment, including an upper mold cavity and a lower mold cavity, the lower mold cavity is installed at the bottom of the upper mold cavity, a convex layer is arranged at the bottom of the upper mold cavity, and a concave layer is opened on the upper end surface of the lower mold cavity to match it, and the concave layer is symmetrically arranged with convex arc surfaces to match it, and the concave layer is symmetrically opened with concave arc surfaces to match it.

[0005] Preferably, the upper end surface of the lower mold cavity is symmetrically provided with positioning columns, and the bottom of the upper mold cavity is symmetrically provided with positioning slots matching with the positioning columns.

[0006] The present invention adopts a sealing method of embedding a convex arc surface into a concave arc surface. Compared with the traditional edge sealing of a concave layer and a convex layer, the structure has less contact, the pressure is more concentrated, and the edge sealing effect is better.

[0011] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the invention, and to enable those of ordinary skill in the art to understand the invention and design various inventions with various modifications suitable for specific uses.

[0012] See also Figures 1 to 3 In the present invention, a foamed silicone mold production equipment is provided, including an upper mold cavity 1 and a lower mold cavity 2, the lower mold cavity 2 is installed at the bottom of the upper mold cavity 1, a convex layer 11 is arranged at the bottom of the upper mold cavity 1, and a recessed layer 12 is provided on the upper end surface of the lower mold cavity 2 to match it, and the recessed layer 12 is symmetrically arranged with convex arc surfaces 13 to match it, and the recessed layer 12 is symmetrically provided with concave arc surfaces to match it. During operation, when the upper mold cavity 1 and the lower mold cavity 2 are fitted together, the convex arc surface 13 is embedded in the concave arc surface. Compared with the traditional edge sealing in which the recessed layer 12 and the convex layer 11 are fitted together, the structure has less contact, the pressure is more concentrated, and the edge sealing effect is better.

[0013] The upper end surface of the lower mold cavity 2 is symmetrically installed with positioning columns 14, and the bottom of the upper mold cavity 1 is symmetrically provided with positioning slots that match it. During operation, the positioning columns 14 are inserted into the positioning slots to ensure that the upper mold cavity 1 and the lower mold cavity 2 are correctly aligned to avoid positional deviation.

[0014] Obviously, the invention described is only a part of the invention of the present invention, not the whole invention. Based on the invention of the present invention, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
