AI Technical Summary
Existing molds used for producing foamed silicone cups have poor edge sealing effects, mainly due to the large contact area of the mold and the dispersion of pressure.
The design employs an upper mold cavity and a lower mold cavity. The bottom of the upper mold cavity is provided with a raised layer, and the upper end face of the lower mold cavity is provided with a recessed layer. The convex arc surface is embedded into the concave arc surface for sealing, which reduces contact points and improves pressure concentration.
It achieves better edge sealing effect, ensures more concentrated pressure during the mold edge sealing process, and improves edge sealing quality.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of silica gel mould production, concretely relates to a foamed silica gel mould production equipment. BACKGROUND
[0002] The cup is an important female daily necessities, and the cups on the market are generally made of sponge, but the main raw material TDI (toluene diisocyanate) in the sponge is a toxic chemical, and long-term contact can harm health. And due to the instability of the molecular structure of the sponge, it is easy to turn yellow, and due to the poor air permeability of the sponge, dirt is easy to hide, in order to solve the above defects of the sponge cup, many manufacturers in the industry try to use foamed silica gel cups to replace the sponge cups.
[0003] The existing foamed silica gel cup production mold directly matches the upper mold cavity and the lower mold cavity to perform edge sealing treatment, the contact area is large, the pressure is dispersed, and the edge sealing effect is poor. UTILITARY MODEL CONTENTS
[0004] In order to solve the above technical problems, the utility model provides a foamed silica gel mould production equipment, including upper mold cavity and lower mold cavity, the lower mold cavity is installed in the upper mold cavity bottom, the upper mold cavity bottom is arranged with the convex layer, the lower mold cavity upper end face is provided with the recess layer matched therewith, the recess layer is arranged with the convex arc surface matched therewith left and right symmetrical, the recess layer is provided with the concave arc surface matched therewith left and right symmetrical.
[0005] Preferably, the lower mold cavity upper end face is installed with the positioning column left and right symmetrical, and the upper mold cavity bottom is provided with the positioning slot matched therewith left and right symmetrical.
[0006] In the utility model, the convex arc surface is embedded into the concave arc surface sealing mode, compared with the traditional recess layer and convex layer edge sealing, the structure contact is less, the pressure is more concentrated, and the edge sealing effect is better.

[0011] The embodiments of the present application are presented by way of example and description, and are not exhaustive or limit the present application to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application in order to design various embodiments with various modifications for specific use cases.
[0012] Please refer to Figs. 1-3 In the embodiment, a foamed silica gel mold production equipment is provided, comprising 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, the upper mold cavity 1 is arranged with a convex layer 11 at the bottom, the upper end surface of the lower mold cavity 2 is provided with a concave layer 12 matched therewith, the concave layer 12 is arranged with a convex arc surface 13 matched therewith in symmetry, and the concave layer 12 is provided with a concave arc surface matched therewith in symmetry. When the upper mold cavity 1 is combined with the lower mold cavity 2, the convex arc surface 13 is embedded into the concave arc surface, compared with the traditional combination of the concave layer 12 and the convex layer 11, the structure has less contact, the pressure is more concentrated, and the sealing effect is better.
[0013] The upper end surface of the lower mold cavity 2 is installed with a positioning column 14 in symmetry, and the bottom of the upper mold cavity 1 is provided with a positioning slot matched therewith in symmetry. When working, the positioning column 14 is inserted into the positioning slot, so as to ensure that the upper mold cavity 1 and the lower mold cavity 2 are correctly positioned, and the positional deviation is avoided.
[0014] Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art and related fields without creative labor should belong to the scope of protection of the present application. The structures, devices and operation methods not specifically described and explained in the present application, if not specially described and limited, are implemented according to the conventional means in the art.
