Abstract

The utility model relates to a screw mould, wherein wing blocks, each two of which are opposite to each other, are arranged on a punch; every two opposite wing blocks are respectively extended and provided with a rib block. The height ratio of the rib block to the punch is between 1:4 and 2:3, which is convenient to form a hole groove as well as a transverse bar shape plow groove on the head part of a screw punched by the screw mould, so as to make the screw applicable to various tools.

Description

Screw mold

Technical field

The utility model relates to a kind of mould design, but particularly relates to the screw mold that the screw that is suitable for multiple instrument use is made in a kind of punching press.

Background technology

The structure of general screw mold roughly as shown in Figure 1, it has a body 11, and these body 11 ends 12 are provided with a groove 13, convex with a drift 14 in this groove 13 in addition, and make this drift 14 peripheries extension be provided with wing piece 141 facing each other, and these wing pieces 141 are more by the supreme heeling condition that is convergent in drift 14 bottoms.

As shown in Figure 2, screw mold 1 after this moulding, but its punching press screw 2 heads 21, moulding corresponds to the drift 14 of screw mold 1, the hole slot 22 of wing piece 141 so that screw 2 heads 21 can be stamped, and this hole slot 22 can be stretched for cross bottle opener and four angle head type bottle openers instruments such as (figure do not show) and put, so that this screw 2 can supply instrument utilizations such as cross bottle opener or four angle head type bottle openers, and then reach the effect that screw 2 rotations can be locked on the working substance.

Though the drift 14 and the wing piece 141 of general screw mold 1 end, though can on screw 2 heads 21, stamp out hole slot 22, so that can utilize instrument to reach the effect that is locked on the working substance on actual the use, but this hole slot 22 can only be stretched for two kinds of instruments such as four angle head type bottle openers or cross bottle openers and put, yet existing instrument commonly used such as yi word pattern bottle opener, then can't be applicable to this screw 2, so, when user's desire during sealed or dismounting screw 2, the user just must change multiple instrument, can reach the sealed or dismounting of screw 2, so, user's activity duration is subject to the replacing of instrument and causes postponing, and then reduction operating efficiency, in addition, more may or leave behind the worker, cause the inconvenience in user's operation because of the searching of instrument.

Summary of the invention

The purpose of this utility model, but be to provide a kind of punching press to make the screw mold of the screw of suitable multiple instrument use.

According to above-mentioned purpose, screw mold of the present utility model is to have a body, and be provided with a groove in this body end, and and in this groove, convex with a drift, and the periphery that makes this drift tilts and is extended with most wing pieces facing each other, and these wing pieces are a heeling condition, in addition, this two corresponding wing piece is provided with a rib piece to extending respectively between groove periphery wall, and make the both sides of the chest piece form yi word pattern, simultaneously, the height of this rib piece is lower than drift, and the height of this rib piece and drift is to be 1: 4 to 2: 3 ratio, by this screw mold punching press screw head, screw head can be stamped out correspond to the drift on the screw mold, wing piece, and the hole slot of rib piece, put so that this screw can be stretched for multiple instrument, and give sealed, all can the multiple current tools of fit applications with the screw head that reaches this screw mold institute punching press, and the convenience that uses with the increase instrument.

Description of drawings

Below by most preferred embodiment and accompanying drawing screw mold of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is the schematic perspective view of general screw mold;

Fig. 2 is the user mode schematic diagram of general screw mold;

Fig. 3 is the schematic perspective view of the utility model one preferred embodiment;

Fig. 4 is the user mode schematic diagram of the utility model one preferred embodiment.

The specific embodiment

As shown in Figure 3, the shown screw mold 3 of present embodiment mainly is to have a body, and this body end 32 is provided with a groove 33, convex with a drift 34 in the groove 33, and make extending again on the periphery of this drift 34 and be provided with most wing pieces 341 facing each other, these wing pieces 341 are by the supreme heeling condition that is convergent in drift 34 bottoms, in addition, this two corresponding wing piece 341 is provided with a rib piece 342 to extending respectively between groove 33 periphery walls, and make both sides of the chest piece 342 form the form of yi word pattern, the height of rib piece 342 is lower than drift 34 simultaneously, and the aspect ratio of rib piece 342 and drift 34 is between 1: 4 to 2: 3, when the height that is to say rib piece 342 is 0.008～0.161mm, the height 0.032～0.260mm of drift 34 then.

As shown in Figure 4, this screw mold 3 utilizes drift 34 in its body recess 33, is formed at the wing piece 341 facing each other of drift 34 peripheries, and extend this two corresponding wing piece 341 respectively to the rib piece 342 between groove 33 periphery walls, and then the head 41 of punching press one screw 4, so that the hole slot 42 that screw 4 heads 41 can be stamped out and correspond to this screw mold 3.

From the above mentioned, present embodiment mainly is to utilize drift set on the screw mold 3 34, wing piece 341, and rib piece 342, when its punching press screw 4 heads 41, make screw 4 heads 41 can corresponding these screw mold 3 ends 32 and be formed with hole slot 42 and yi word pattern groove, so that these hole slots 42 can supply cross bottle opener, four angle head bottle openers, and instrument such as yi word pattern bottle opener is stretched and is put and sealed, more make screw 4 so that multiple instrument carries out sealed action, because the more general screw mold more than 1 of present embodiment is provided with a rib piece 342, though this kind screw mold 3 existing many dealers develop manufacturing, only be subject to the drift 34 of the screw mold of its manufacturing, wing piece 341 and rib piece 342, the intensity of the metal material when moulding in it can't reach optimization because of the cause of many rib pieces 342, and then screw mold is usually damaged, so this screw mold can't make screw mold have best intensity on forming technique, therefore the utility model is after considering in many ways factor, the aspect ratio that just must produce rib piece 342 and drift 34 is the screw mold 3 between 1: 4 to 2: 3, gives the screw head design that multiple instrument use is provided in moulding so that the rib piece 342 of this screw mold 3 can have maximum intensity with drift 34.

Claims

1. screw mold, it has a body, and this body end is provided with a groove, and convex with a drift in this groove, the circumferential surface of this drift tilts to be extended with several corresponding wing pieces, it is characterized in that: wantonly two corresponding wing pieces are provided with a rib piece to extending respectively between groove periphery wall, and make the both sides of the chest piece form yi word pattern, the height of these rib pieces is lower than the top edge of drift, and the aspect ratio of this rib piece and drift is 1: 4 to 2: 3.
