The utility model aims to solve the technical problem that a die casting die for gold and silver goods is provided, simple structure has reduced the material quantity when making the outward appearance of gold (silver) strip (coin, chapter) goods keep relief (sculpture) visual effect, the cost is reduced.
In order to solve the technical problem, the utility model discloses the technical scheme who takes is: the die-casting die for gold and silver products is characterized by comprising an upper die, wherein the lower surface of the upper die is provided with at least two positioning columns, and the lower surface of the upper die is provided with a male surface relief;
the die comprises a die frame, wherein the upper surface of the die frame is provided with a positioning hole corresponding to a positioning column, the die frame is provided with an accommodating hole along the axis, a lower die is arranged in the accommodating hole, a rough blank is arranged between the upper die and the lower die in the accommodating hole, and a groove is formed in the contact surface of the rough blank and the upper die;
preferably, the positive relief shape is a figure required to be engraved and formed by the gold and silver product.
Further preferably, the shape and size of the groove are adapted to the male relief.
Still further preferably, the grooves are reverse female-faced engravings with draft greater than or equal to 5 °.
Preferably, the draft angle of the male relief is greater than or equal to 5 °.
Preferably, a spherical engraving tool with the diameter of 0.1mm is used for carrying out the last engraving process when the male surface relief is engraved.
Preferably, the contact surface of the lower die and the rough blank is a plane.
Adopt the produced beneficial effect of above-mentioned technical scheme to lie in: the utility model discloses an go up the mould and be equipped with the positive relief (sculpture), the rough blank of use have with the recess of positive relief (sculpture) looks adaptation, the lower mould is the plane with the contact surface of rough blank, when making finished product have with the same or better visual effect of positive relief (sculpture), has reduced the use material of rough blank, the cost is reduced.
Drawings
FIG. 1 is an exploded view of the overall structure of the present invention;
FIG. 2 is a schematic view of a reverse negative relief state;
FIG. 3 is a schematic view of the male relief state;
in the figure: 1. the die comprises a male surface relief 2, an upper die 3, a positioning column 4, a groove 5, a positioning hole 6, a die frame 7, a lower die 8, a rough blank 9 and a containing hole.
Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1 and 3, a die casting die for gold and silver goods comprises an upper die 2, wherein a male surface relief 1 is arranged on the lower surface of the upper die 2, the shape of the male surface relief 1 is a figure required to be carved and formed by the gold and silver goods, the male surface relief 1 in the embodiment is the head of a mouse, the head of the mouse protrudes out of the lower surface of the upper die 2, the pattern drawing inclination of the mouse is greater than or equal to 5 degrees when the head of the mouse is carved, 7 degrees are taken, and the last carving process is carried out by a spherical carving tool with the diameter of 0.1mm so as to optimize the fineness degree of the relief of the head. The lower surface of the upper die 2 is provided with two positioning columns 3, and when the die is used, the positioning columns 3 are inserted into positioning holes 5 in the upper surface of a die frame 6 to limit the position of the upper die 2;
as shown in fig. 1 and 2, a containing hole 9 is formed in the mold frame 6 along the axis, the lower mold 7 is arranged in the containing hole 9, a circle of bosses can be arranged in the containing hole 9, and the lower mold 7 is placed on the bosses. The contact surface of the rough blank 8 and the upper die 2 is provided with a groove 4, the groove 4 is carved by a reverse negative surface, the draft angle is greater than or equal to 5 degrees, the angle is 7 degrees, and the shape and the size of the groove 4 are matched with the head of a mouse on the upper die 2. The size calculation of the groove 4 is the same as the conventional method for calculating the groove reserved by the upper die during the production of the male relief product, the rough blank 8 is manufactured in a casting mode, and the groove 4 is directly cast.
The process for making the blank 8 is as follows: 1. firstly, manufacturing a female die of a rough blank 8: a. manufacturing a wax piece in a reverse negative relief mode; b. putting the manufactured wax piece into the gypsum slurry, and reserving wax hole positions; c. heating and curing the gypsum slurry to form gypsum parts, and simultaneously melting and reserving the wax parts to form an inner cavity gypsum female die with a negative relief; 2. casting a rough blank 8: d. pouring molten gold or molten silver into the wax holes of the gypsum master model; e. cooling to form a gold or silver green cake; f. putting the gypsum part with the gold or silver blank cake into water to dissolve the external gypsum, and taking out the gold or silver blank cake; g. and removing the redundant part of the gold or silver blank cake, simply polishing, and finishing the rough blank 8.
The die frame 6 all is connected with the die casting machine with last mould 2, when carrying out the die-casting to rough blank 8, at first puts rough blank 8 on lower mould 7, and rough blank 8 just in time blocks into the holding hole 9 on the die frame 6, starts the die casting machine, goes up mould 2 and pushes down, goes up mould 2 positive relief (sculpture) 1 just in time and impresses in the recess of rough blank 8, and lower mould 7 is the plane with the contact surface of rough blank 8, forms the reverse negative relief (sculpture) of the head of mouse in the recess of rough blank 8.
The gold (silver) strip (coin, chapter) that utilizes this mould preparation has the visual effect of the three-dimensional relief (sculpture) of conventional positive face when its rotation is rocked, still can produce the visual illusion that the relief (sculpture) is drawing the sight motion, thereby can reduce gold (silver) material weight reduce cost in a large number again, thereby the whole cost is expected to have reduced about 50%, reverse negative relief (sculpture) is darker, the area is more economized the cost more greatly, thereby can reduce market retail price, drive more consumers and purchase.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
