Abstract
The utility relates to a microphone stamping die comprising an upper die, a lower die, an upper die set, a lower die set, a guide pillar, a punch needle and a blanking hole, wherein the punch needle is arranged in a die cavity of the upper die; the upper die is arranged on the upper die set; the blanking hole is arranged on the lower die; the lower die is arranged on the lower die set; the guide pillar is arranged between the upper die and the lower die so that the punch needle is right opposite to the blanking hole; the punch needle is circular; and a dodge hole is arranged at the bottom of the punch needle. In the microphone stamping die, as the dodge hole is arranged at the bottom of the punch pin, the punch needle can keep away from a microphone when punching downwards to avoid damaging a bonding chip. Therefore, the microphone stamping die can achieve the function of rapidly punching the microphone off, and greatly improve the production efficiency.
Description
Technical field
The utility model relates to a kind of miaow primary drying pressing mold tool, and particularly a kind of miaow primary drying pressing mold tool that can improve the first-born product efficient of miaow belongs to the mould molding technical field.
Background technology
In the prior art, the miaow head of electroacoustic series products, it is circular that this type of product design mostly is, and diameter has 3.7mm, 5.5mm etc.; Described miaow head base material generally is with PC B plate; The common processing method of this series products is the subpunch circular PCB base material that falls, and then, client's paster on every PCB base material is made the miaow head, and efficient is very low; By the diel (as shown in Figure 1) that described method is provided with, comprise upper die and lower die, top mold frame, down mould bases, guide pillar, towards pin, material-dropping hole; In the described die cavity that is arranged on patrix towards pin; Described patrix is arranged on the top mold frame; Described material-dropping hole is arranged on the counterdie; Described counterdie is arranged on down on the mould bases; Be provided with guide pillar between described upper die and lower die, just make and dash at material-dropping hole; Described is circular towards pin; Described PC B plate is passed by from the counterdie upper surface, under the pin towards circular miaow head base material.
The utility model content
The utility model purpose is to have proposed a kind of miaow primary drying pressing mold tool that can improve the first-born product efficient of miaow in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of miaow primary drying pressing mold tool, comprise upper die and lower die, top mold frame, down mould bases, guide pillar, towards pin, material-dropping hole; In the described die cavity that is arranged on patrix towards pin; Described patrix is arranged on the top mold frame; Described material-dropping hole is arranged on the counterdie; Described counterdie is arranged on down on the mould bases; Be provided with guide pillar between described upper die and lower die, just make and dash at material-dropping hole; Described is circular towards pin; Described bottom towards pin is provided with dodges the hole.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Miaow primary drying pressing mold tool of the present utility model can be provided with towards the bottom of pin and dodge the hole, can under pin towards the time, avoid the miaow head, so as not to the injury paster; So just can realize the function of dashing the miaow head fast providing production efficiency widely.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1 is the partial sectional view of the miaow primary drying pressing mold tool of prior art;
Fig. 2 is the partial sectional view of miaow primary drying pressing mold tool of the present utility model;
Wherein: 1, patrix; 2, counterdie; 3, top mold frame; 4, following mould bases; 5, guide pillar; 6, towards pin; 7, material-dropping hole; 8, pcb board; 11, patrix; 12, counterdie; 13, top mold frame; 14, following mould bases; 15, guide pillar; 16, towards pin; 17, material-dropping hole; 18, pcb board; 19, dodge the hole; 20, paster.
The specific embodiment
Be illustrated in figure 2 as a kind of miaow primary drying pressing mold tool described in the utility model, comprise patrix 11, counterdie 12, top mold frame 13, down mould bases 14, guide pillar 15, towards pin 16, material-dropping hole 17; In the described die cavity that is arranged on patrix 11 towards pin 16; Described patrix 11 is arranged on the top mold frame 13; Described material-dropping hole 17 is arranged on the counterdie 12; Described counterdie 12 is arranged on down on the mould bases 14; 12 of described patrix 11 and counterdies are provided with guide pillar 15, just make towards pin 16 facing to material-dropping hole 17; Described is circular towards pin 15; Described bottom towards pin 15 is provided with dodges hole 19; Have paster 20 to pass by on the described pcb board 18 from the counterdie upper surface, towards pin 16 times towards circular miaow head; Paster just can be avoided in the described hole 19 of dodging, to avoid damaging paster 20.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Miaow primary drying pressing mold tool of the present utility model can be provided with towards the bottom of pin and dodge the hole, can under pin towards the time, avoid the miaow head, so as not to the injury paster; So just can realize the function of dashing the miaow head fast providing production efficiency widely.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
