Detailed Description

The invention is further explained below with reference to the drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

The first embodiment is as follows: as shown in fig. 1, 2 and 3, the split type silica gel forming mold comprises at least two thin-wall split molds 1 which can enclose a forming cavity 4 together, and the mold in a thin-wall form has better ductility and heat dissipation compared with a structure of slotting on an entity mold base in the prior art. Preferably, the wall thickness of the thin-wall split mold 1 at the molding cavity 4 is equal, so that the material in the molding cavity 4 can form uniform heat dissipation in all directions, and the solidification efficiency can be improved.

And a mold closing plane 5 which can be mutually pressed is respectively arranged between two adjacent thin-wall mold halves 1, and a mold opening seam is formed at the position of the two mold closing planes 5 which are mutually pressed.

Pressing fins 6 are integrally arranged on the thin-wall split dies 1 at the die assembly plane 5, and the pressing fins 6 on the thin-wall split dies 1 are respectively connected with a pressing frame 7. In the embodiment, the mode that the prior art directly presses the die holder to the forming cavity 4 is changed into the mode that indirect pressing is formed by the pressing fins 6 from the outside of the die opening seam, so that the pressure in the forming cavity 4 can be obviously reduced, the material is not extruded outwards to the die opening seam due to overlarge pressure in the forming process, obvious burrs are not generated after the material is solidified and formed, and the appearance is more attractive.

Preferably, the mold closing plane 5 on which two adjacent thin-wall parting molds 1 can be pressed together is respectively and correspondingly provided with a male seam allowance 8 and a female seam allowance 9. The arrangement of the convex spigot 8 and the concave spigot 9 can prolong the cross section length of the die opening seam and enable the shape of the die opening seam to be more zigzag, and can further reduce the extrusion of materials to the outside of the die opening seam, thereby further improving the appearance attractiveness of a finished product 10.

In the present embodiment, the two thin-wall split dies 1 jointly enclose the forming cavity 4, so that each forming cavity 4 has only one die closing plane 5, and the pressing fin 6 located at the die closing plane 5 is also in a flat closed ring shape. Correspondingly, the pressing frame 7 of the present embodiment may be configured to be a flat closed-loop plate. The pressing frame 7 is a rigid structure and can be pressed on the pressing fins 6 through external force, so that the two adjacent pressing fins 6 can form extrusion, the extrusion force can be indirectly transmitted to the thin-wall die 1, and the material can be kept in the forming cavity 4 until forming.

In the present embodiment, because of the arrangement of the thin-wall split dies 1, the present embodiment can use a molten liquid material with high fluidity, which can be injected into the forming cavity 4 through a tubular apparatus, and then the two thin-wall split dies 1 are closed through the pressing frame 7, unlike the prior art that uses a semi-solidified material. The pressing force indirectly acts in the forming cavity 4, the liquid material in the forming cavity 4 is pressed less, meanwhile, due to the thin wall arrangement of the thin wall die 1, the better ductility can further buffer the pressure in the forming cavity 4, the liquid material in the forming cavity 4 cannot be extruded outwards towards the die opening seam, and the outward protruding of the material due to the existence of the die opening seam is not easy to occur, so that after the material is solidified into a finished product 10, the surface of the finished product 10 is smooth and has no burrs, and the attractiveness is improved. In the present embodiment, the molding cavity 4 may not be filled when in use, and certainly, when the volume of the required liquid material is smaller than the capacity of the cavity on any one of the thin-wall split molds 1, the liquid material may be directly placed on the thin-wall split mold 1 without adopting a material injection manner, and then the other thin-wall split mold 1 is pressed. After the material is not filled and pressed, the pressing frame 7 can be clamped on relevant equipment and then rotates in multiple directions, the liquid material can be slowly solidified along the wall in the forming cavity 4, and finally a hollow finished product 10 can be formed.

Therefore, the present embodiment can better adapt to the molding of other complex three-dimensional shapes through simple structural changes, improve the beauty of the finished product 10, facilitate the manufacture of the hollow finished product 10, and have high popularization value.

In this way, the pressing frame 7 corresponding to the main parting die 2 is in a flat closed-loop plate shape, and the pressing frame 7 corresponding to the auxiliary parting die 3 is in a 7-shaped bent closed-loop shape.

In this embodiment, more thin-wall split molds 1 are used, so that the forming of more complex three-dimensional shapes can be adapted, for example, if animal-shaped objects with four convex feet are obvious, most of the body can be arranged in the cavity of the main split mold 2, and the two front legs and the two rear leg parts can be respectively arranged in the cavities of the two sub-split molds 3.

The basic principles, main features and advantages of the present invention have been shown and described above.
