Description

A kind of mold doing thin head screw head

Technical field

The utility model belongs to technical field of mold, and in particular to a kind of mold doing thin head screw head.

Background technology

Currently, in the production process of thin head screw, very thin for the matrix that does thin head screw head, some thickness is only For 0.8mm or so, the matrix of this thickness, according to being produced after being conventionally loaded into formwork, a upsetting just will appear rupture, and hold very much It is easily pulled out from formwork oral area, formwork is caused to damage.Therefore, it is necessary to design a kind of novel mold to solve the above problems.

Invention content

To overcome above-mentioned deficiency in the prior art, the utility model aim, which is to provide, a kind of doing thin head screw head Mold.

In order to achieve the above objects and other related objects, technical solution provided by the utility model is：One kind doing thin head spiral shell The mold on silk head, including thick matrix, the thickness matrix is a round platform, and the busbar of the round platform and high angle are 5 °, described Thick matrix upper end is provided with die hole, and the depth of the die hole is corresponding with the thin thickness on head screw head, the thickness matrix Lower end is provided with the mounting hole more than the die hole aperture, and convex internal model, the convex internal model are provided with below the mounting hole Middle part is provided with vertical through hole, and formwork is provided on the outside of the convex internal model, thick matrix.

Preferably technical solution is：The die cap for locking convex internal model is provided on the inside of the formwork lower end.

Preferably technical solution is：The formwork is connected through a screw thread with the die cap.

Since above-mentioned technical proposal is used, the utility model this have the advantage that compared with prior art：

The utility model avoids matrix because excessively thin and burst by increasing the thickness of matrix, while increasing matrix and mould The contact surface of shell, pulls out so as to avoid matrix from formwork easily, and clever structure is at low cost, and practicability is high.

Description of the drawings

Fig. 1 is utility model diagram.

Fig. 2 is thick matrix schematic diagram.

In the figures above, thick matrix 1, die hole 2, mounting hole 3, convex internal model 4, through hole 5, formwork 6, die cap 7.

Specific implementation mode

Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below Content disclosed by specification understands other advantages and effect of the utility model easily.

Please refer to Fig.1 ~ Fig. 2.It should be clear that structure, ratio, size etc. depicted in this specification institute accompanying drawings, only to Coordinate the revealed content of specification, so that those skilled in the art understands and reads, is not limited to the utility model Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size Adjustment, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model Revealed technology contents obtain in the range of capable of covering.Meanwhile in this specification it is cited as "upper", "lower", " left side ", The term on " right side ", " centre " and " one " etc. is merely convenient to being illustrated for narration, rather than enforceable to limit the utility model Range, relativeness are altered or modified, enforceable when being also considered as the utility model in the case where changing technology contents without essence Scope.

As shown in Fig. 1 ~ Fig. 2, a kind of mold doing thin head screw head, including thick matrix 1, thick matrix 1 are a round platform, The busbar of round platform and high angle are 5 °, and 1 upper end of thick matrix is provided with die hole 2, the thickness of the depth of die hole 2 and thin head screw head To spend corresponding, 1 lower end of thick matrix is provided with the mounting hole 3 more than 2 aperture of die hole, and 3 lower section of mounting hole is provided with convex internal model 4, 4 middle part of convex internal model is provided with vertical through hole 5, and convex internal model 4,1 outside of thick matrix are provided with formwork 6.

Note：The depth of die hole 2 is corresponding with the thin thickness on head screw head not to be implied that equal, for example does head thickness The screw of 1mm, it is desirable that the matrix of 0.8mm, other specific sizes correspond to the relevant technological parameter of the technical field and come really It is fixed.

Preferred embodiment is：As shown in Figure 1, being provided with the mould for locking convex internal model 4 on the inside of 6 lower end of formwork Lid 7.Convex internal model 4 is locked, ensures product quality.

Preferred embodiment is：As shown in Figure 1, formwork 6 is connected through a screw thread with die cap 7.Screw thread process is convenient, connection Securely, it is conveniently operated.

Example：Using the thick matrix 1 of 4mm, then vehicle makes mounting hole 3 and die hole 2, the height of mounting hole 3 in thick matrix 1 For 3.2mm, while the convex internal model 4 that vehicle system is matched, after working good, then it is pressed into together along angle in the formwork 6 made, Cold upsetting production, matrix thickness is gone to increase again, the contact surface of matrix and formwork 6 also increases, and matrix will not be drawn from 6 oral area of formwork easily Out.

The utility model avoids matrix because excessively thin and burst by increasing the thickness of matrix, while increasing matrix and mould The contact surface of shell, pulls out so as to avoid matrix from formwork easily, and clever structure is at low cost, and practicability is high.

The above embodiments are only illustrative of the principle and efficacy of the utility model, new not for this practicality is limited Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model All equivalent modifications completed under refreshing and technological thought or change, should be covered by the claim of the utility model.
