Description

In-mould injection is placed the nut tool

Technical field

The utility model relates to a kind of tool that is used to place nut when being used for in-mould injection, particularly relates to the tool that is used for placing simultaneously a plurality of small-sized nuts.

Background technology

Along with science and technology develops rapidly, more and more electronic products develop towards accurate and small and exquisite direction, this just makes various spare and accessory parts, particularly casing to develop towards miniaturization, and small-sized electronic product mechanization High-efficient Production is the big problem that people need pay close attention to always.Production as most typical phone housing, a plurality of small-sized nuts need be installed on shell, provide connector when assembling, and in-mould injection section injection moulding nut all is pure manual the placement at present, because the size of small-sized nut is little with mobile phone, and mould also has other structure around putting nut, cause placement speed slow, the position of placement is also not accurate enough, and production efficiency is low, the phenomenon of being scalded appears in operational hazards, operating personnel's hand easily.

Summary of the invention

In sum, the purpose of this utility model is that the in-mould injection that proposes in a kind of nut die cavity that a plurality of nuts can be placed on fast injection mould is simultaneously placed the nut tool.

For achieving the above object, the technical solution adopted in the utility model is: the utility model comprises movable floor, fixed head, handle plate, connecting rod, nut loop bar, and described movable floor is fixedly connected on the bottom of connecting rod; Described handle plate is fixedly connected on the connecting rod top; Described fixed head is provided with the connecting rod through hole, and fixed head is actively socketed on the connecting rod by the connecting rod through hole; Described nut loop bar has one at least, and the top of nut loop bar is fixedly connected on the fixed head, and described movable floor is provided with the nut sleeve pole pair answers nut to eject sleeve pipe, and nut ejects sleeve pipe and is actively socketed on the nut loop bar; Also be provided with reference column on the described fixed head.

As the technical scheme that the utility model is further improved be: the described connecting rod that is between handle plate and fixed head is provided with spring part.

Described and nut loop bar is a hollow stem, is provided with pilot pin in the bar, and an end of pilot pin places outside the nut loop bar bottom, and the other end is connected on the fixed head by spring.

Be provided with stoping block between described movable floor and fixed head.

Described movable floor is provided with the reference column through hole, and the bottom of reference column places the bottom of movable floor through the reference column through hole.

The beneficial effects of the utility model are: nut is placed on the nut sleeve bar, after pilot pin is accurately located, after pressing handle plate, nut on each nut loop bar just can be ejected sleeve pipe by nut simultaneously and eject, be placed in the nut die cavity of injection mould, easy to operate, improved operating efficiency and output, the adversary does not have scald, high safety.

The specific embodiment

Below in conjunction with the drawings and specific embodiments structure of the present utility model is further described:

Shown in Fig. 1,2,3, comprise movable floor 1, fixed head 2, handle plate 3, connecting rod 4, nut loop bar 5.Movable floor 1, fixed head 2 and handle plate 3 stack from top to bottom successively, fixed head 2 is provided with connecting through hole 21, described connecting rod 4 is through connecting through hole 21, two ends are connected on movable floor 1 and the handle plate 3, and fixed head 2 can be free up and down between movable floor 1 and handle plate 3 along connecting rod 4.The four jiaos of reference columns 22 that respectively are provided with an equal height in the bottom surface of described fixed head 1, pass the bottom that reference column through hole 13 places movable floor 1 respectively and on movable floor 1, be provided with four 13, four reference columns 22 of reference column through hole corresponding with four reference columns 22.

Quantity and placement location that nut is placed according to need in the quantity of described nut loop bar 5 and the position of distribution are decided, the top of nut loop bar 5 is fixedly connected on the bottom of fixed head 2, eject sleeve pipe 11 and also be provided with on the movable floor 1 with nut loop bar 5 corresponding nuts, nut loop bar 5 bottoms can be passed nut and eject the bottom that sleeve pipe 11 arrives movable floor 1.During use, with nut sleeve on the nut loop bar 5 that passes from movable floor 1 bottom, when when handle plate 3 applies downward pressure, since the connecting rod 4 fixedly connected handle plate 3 and the association's base plate 1 of living, movable floor 1 will move down, again because nut ejects fixedly movable floor 1 of sleeve pipe 11, be socketed on the nut loop bar 5, and be in the nut top, nut will be ejected sleeve pipe 11 by nut and eject downwards, realizes once placing in the nut die cavity of injection mould the operation of nut.

For standard more places nut definitely, shown in Fig. 4, nut loop bar 5 is a hollow stem, be located at the pilot pin 51 of stretching out on the bottom, the inside, top of pilot pin 51 other ends and nut loop bar 5 is provided with spring 52, when the end that pilot pin 51 is stretched out is subjected to stoping power, to the 5 inner withdrawals of nut loop bar.

Shown in Fig. 1, the utility model resets after having placed nut for convenience, is provided with spring part 41 on the connecting rod 4 of 2 of handle plate 3 and fixed heads; In addition, excessive for fear of spring part 41 elastic force, movable floor 1 moved with fixed head 2 to fitting together, it is bad that nut loop bar 5 and reference column 22 lose the stressed folding of support force, and two stoping blocks 12 equably distribute on movable floor 1 upper surface.
