Description
Technical Field
The application relates to the technical field of molding, in particular to a mold.
Background
In the process of forming the shell by the plate, the plate needs to be subjected to a plurality of processes, specifically, 4-5 printing inks need to be printed on the bottom cover, so that the problems of point offset printing, top printing appearance defects and monomer auxiliary material printing through surface appearance defects still easily occur on the front surface of the shell after forming, and the mode of printing the printing inks is not beneficial to environmental protection.
SUMMERY OF THE UTILITY MODEL
The utility model provides a mould is provided with the silica gel layer through the mold core surface at the lower mould, makes panel when the shaping is the casing, makes the surface of casing defect can not appear.
In order to achieve the above object, the present invention provides the following technical solutions:
the application provides a mold, including: an upper die and at least one lower die;
the upper die is arranged opposite to at least one lower die, and the upper die can move to the position of the lower die;
the lower die comprises a die core and a silica gel layer, wherein a bulge is arranged on one side of the die core, which faces the upper die, the silica gel layer is arranged on the surface of the bulge, and the shape of the silica gel layer is the same as that of the bulge; go up the mould orientation one side of lower mould be equipped with protruding complex depressed part, the depressed part with protruding cooperation is in order to be used for shaping panel.
The mold comprises an upper mold and at least one lower mold, wherein the lower mold comprises a mold core, a protrusion is arranged on one side, facing the upper mold, of the mold core, a concave part matched with the protrusion is arranged on the upper mold, when the plate body is molded, the plate body is located between the protrusion and the concave part, and the concave part moves to the position of the protrusion, so that the molding of the plate body is completed; because, the bellied surface is equipped with the silica gel layer, and the silica gel layer closely contacts with the silica gel face when high pressure blow forming or last mould extrusion have the buffering and exhaust effect better than the steel mould, can solve the negative and positive impression problem and the not problem of fold bump of pad pasting high pressure forming.
Preferably, the silica gel layer is poured into a whole on the mold core.
Preferably, the thickness of the silica gel layer is 0.4mm-0.6 mm.
Preferably, the PC film is used for being attached to the plate.
Preferably, the PC film has a black material therein.
Preferably, the PC film is adhered to a plate.
Drawings
Fig. 1 is a schematic structural diagram of a mold according to an embodiment of the present application.
Icon: 10-a mold core; 20-bulge; 30-silica gel layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a mold, including: an upper die and at least one lower die;
the upper die is arranged opposite to at least one lower die, and the upper die can move to the position of the lower die;
the lower die comprises a die core 10 and a silica gel layer 30, wherein a protrusion 20 is arranged on one side, facing the upper die, of the die core 10, the silica gel layer 30 is arranged on the surface of the protrusion 20, and the shape of the silica gel layer 30 is the same as that of the protrusion 20; go up the mould orientation one side of lower mould be equipped with protruding 20 complex depressed part, the depressed part with protruding 20 cooperation is used for shaping panel.
The mold comprises an upper mold and at least one lower mold, specifically, the lower mold comprises a mold core 10, a protrusion 20 is arranged on one side, facing the upper mold, of the mold core 10, a concave part matched with the protrusion 20 is arranged on the upper mold, when the plate body is molded, the plate body is located between the protrusion 20 and the concave part, and the concave part moves to the position of the protrusion 20, so that the molding of the plate body is completed; because the surface of the bulge 20 is provided with the silica gel layer 30, the silica gel layer 30 is in close contact with the silica gel surface during high-pressure air blowing forming or upper die extrusion forming, and the air exhaust effect is better than that of a steel die, so that the problems of negative and positive marks and wrinkle salient points of film pasting high-pressure forming can be solved.
As an optional way, in order to improve the stability of the connection between the silica gel layer 30 and the mold core 10, the silica gel layer 30 is cast integrally with the mold core 10.
As an alternative, the thickness of the silica gel layer 30 is 0.4mm to 0.6 mm. Thus, the silica gel layer 30 can not generate marks during high-pressure molding, and the silica gel layer 30 is not too thick, so that the material is wasted. Preferably, the thickness of the silicone gel layer 30 may be 0.5 mm.
As an alternative, a PC film for attaching to the panel is also included. And the PC film has a black material therein. In the specific implementation, the plate is subjected to high-pressure forming after being subjected to printing of a logo-offset printing-UV transfer printing-electroplating-bonding PC film. The problems of glue dispensing, top impression and monomer auxiliary material printing after the whole machine is assembled can be solved. In addition, the plate is firstly attached with the PC film, and the plate is not limited by the radian depth and the structure during forming, so that the common battery cover structure and the 3.5D (4D) structure effect of the radian depth of the plate can be met; the mode also replaces printing ink, so that the production process is more environment-friendly.
It will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments of the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
