On be provided with upper mold boss 11 and support portion 12, upper mold boss 11 is set on 10 bottom surface of upper mold, the mold can be saved
Production cost, support portion 12 is looped around around upper mold boss 11, and lower die groove 21 and lower die ball are provided in lower die 20
Slot 22, lower die groove 21 is to place glass raw material to be processed, and lower die ball grooves 22 are for placing ball 30, lower die ball grooves
22 are surrounded on lower die groove 21, and multiple balls 30 are installed in lower die ball grooves 22, and upper mold boss 11 is inserted in lower die groove 21,
Support portion 12 is connected to ball 30 so that upper mold boss 11 and the bottom surface of lower die groove 21 are mutually parallel before molding, avoid
Lead to glass raw material fragmentation due to placing uneven between upper mold boss 11 and lower die groove 21.
In the present embodiment, upper mold boss 11 is equipped with molding boss 111, is molded position and the lower die groove 21 of boss 111
Position it is corresponding, be molded between boss 111 and the bottom surface of lower die groove 21 and constitute a product cavity, glass raw material is being molded
Boss 111 is suppressed to form preset shape of product under 21 collective effect of lower die groove in product type intracavitary.
Since the mold is mainly used for the cell phone rear cover of pressure zone camera, position of the rear cover with camera be it is raised,
The more difficult pressure of position height, often occur in compacting pressure it is uneven or stretch phenomenon than it is more serious the problems such as, therefore in the present embodiment, at
It is provided with phase head boss 1111 on type boss 111, it is corresponding in lower die groove 21 to be provided with phase head groove 211, phase head
It is inserted in phase head groove 211 with boss 1111, until phase head boss 1111 and phase head groove 211 abut against, is being suppressed
When processing glass raw material, relative to through-hole is formed at phase head 1111 position of boss, which takes the photograph glass raw material for mobile phone
It being used when being installed as head, phase head boss 1111 is located at the upper side of molding boss 111, in the present embodiment, phase head boss
1111 are located at 111 upper left side of molding boss.
As preferred embodiment, lower die ball grooves 22 include multiple lower die ball grooves 221, and multiple lower die balls are recessed
Slot 221, which is respectively separated, to be arranged on support portion 12, and multiple lower die ball grooves 221 are surrounded on around lower die groove 21, specifically
Say, the lower die ball groove 221 in the present embodiment be six, be respectively arranged at 21 both sides of lower die groove, be uniformly distributed in branch
On support part 12.
As preferred embodiment, lower die ball positioning groove 2211 is provided in lower die ball groove 221, ball 30 is pacified
Loaded on lower die ball positioning groove 2211, the effect of lower die ball positioning groove 2211 is to prevent ball 30 in lower die ball groove
It is shaken in 221, influences glass raw material processing.
As preferred embodiment, upper mold ball corresponding with lower die ball groove 221 is provided on support portion 12
Groove 121, upper mold ball groove 121 are connected to ball 30, and the effect of upper mold ball groove 121 is to realize upper mold 10 relative to rolling
Primary Location on pearl 30, in order to be processed to glass raw material.
As preferred embodiment, upper mold ball positioning groove 1211, upper mold ball are provided in upper mold ball groove 121
Locating slot 1211 is connected to ball 30, and the effect of upper mold ball positioning groove 1211 is to prevent ball 30 in upper mold ball groove 121
Interior shaking influences glass raw material processing.
As preferred embodiment, ball 30 is bead, and the fusing point of glass is low, bead manufacturing cost is low, is suitble to
It is a wide range of to use.
Glass raw material is placed into lower die groove 21, passes through when carrying out press process on bending shaping machine by the mold
The bead for supporting upper mold 10 is placed on lower die ball groove 221, upper mold 10 carries out press process with the molding of lower die 20
Before, bead can support upper mold 10, and upper mold boss 11 and the bottom surface of lower die groove 21 is made to be mutually parallel before molding, upper mold 10,
Lower die 20 and glass raw material can gradually heat up under the heat effect of bending shaping machine, and glass raw material is by thermal softening, and glass
Pearl also can be carried out press process, glass under the heat effect of bending shaping machine by thermal softening, at this moment upper mold 10 and the molding of lower die 20
Glass pearl softens fragmentation under the effect of the pressure of upper mold 10 and lower die 20 so that upper mold 10 is moved to the bottom of lower die 20, glass
Embryo material can also deform under the promotion of upper mold 10 and under high temperature, finally in the effect of molding boss 111 and phase head boss 1111
Under be pressed into predetermined shape, form final products.
For fool proof, ensures that upper mold 10 is accurately molded with lower die 20, have in four chamferings of the upper mold 10 of the present embodiment
One is fillet, remaining is right angle；Corresponding in four chamferings of lower die 20 there are one being fillet, remaining is right angle, molding
When, so that the fillet of upper mold 10 is directed at the fillet of lower die 20, so that it may ensure accurate molding.
The material of upper mold 10 and lower die 20 in the present embodiment is isostatic pressing formed graphite.
By using the mold of above structure, upper mold boss 11 is set on 10 bottom surface of upper mold, and upper mold boss 11 is inserted in
Lower die groove 21,30 one end of ball are connected on lower die ball grooves 22, and 30 other end of ball is connected to support portion 12 so that the mould
The upper mold boss 11 of tool is mutually parallel with the bottom surface of lower die groove 21 before molding, avoids upper mold boss 11 and lower die groove 21
Between the phenomenon that injustice leads to glass raw material fragmentation placed due to the two occur, and then reduce spillage of material, also reduce plus
Work cost.
The above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model range claimed.
