Description

Tape measure button mould

Technical Field

The utility model relates to the field of molds, especially, relate to a tape measure button mould.

Background

The tape measure button mould in the prior art comprises an upper mould plate, a cavity plate, a lower mould plate and other auxiliary components, wherein the upper surface of the lower mould plate is carved with a mould cavity for injection molding of a tape measure button. The tape measure button mould in the prior art has the defects that: 1. the matching of the die cavity and the die cavity plate generated by engraving is easy to lose efficacy gradually along with the increase of the service time, so that the quantity of qualified products produced by the die is reduced, and a tape measure button with flash is easy to appear in the later period; 2. the upper template and the cavity plate are of an integrated structure, so that later maintenance is not facilitated; 3. the needle return plate is easily deformed in long-term use.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that prior art's tape measure button mould life is not enough, and the later stage makes the tape measure button of moulding plastics out easily have the overlap.

In order to solve the technical problem, the utility model discloses a technical scheme does: a tape measure button mould comprises an upper mould plate, a cavity plate, a lower mould plate, a back needle plate, mould feet and a base which are arranged from top to bottom;

the lower template falls on the die legs, the needle return plate is positioned between the two die legs, and the needle return plate is used for mounting a reset rod;

the upper template and the cavity plate are split, and the design is beneficial to a user to separately maintain and maintain the upper template and the cavity plate after the mould is used for a period of time; the cavity plate and the lower die plate are processed by a linear cutting process, the cavity plate and the lower die plate are combined to form a die cavity in the middle, and the linear cutting process belongs to one-step forming, so that all contact surfaces of the cavity plate and the lower die plate have good consistency, all contact surfaces of the cavity plate and the lower die plate can be well attached after die assembly, and the phenomenon that plastic overflows to cause flash of a tape button in the injection molding process is avoided.

Furthermore, the needle returning plate comprises an upper needle returning plate and a lower needle returning plate, and the thickness of the upper needle returning plate is smaller than that of the lower needle returning plate; the traditional design that returns needle board and lower needle board isopachous does not accord with the atress condition of going up needle board and lower needle board in practical application, carries out the design that the thickness is different with last needle board and lower needle board and can show the holistic deformation that reduces the needle board that returns.

Further, a base plate is arranged below the lower die plate, falls on the die feet, and can reduce deformation of the lower die plate.

Furthermore, the mould foot and the base are fixed through bolts, and when the mould foot and the injection molding machine plate are installed, the mould foot and the injection molding machine plate are close to each other, so that the stability of the base and the whole mould is kept.

Has the advantages that: (1) the utility model discloses a tape measure button mould uses wire-electrode cutting technology processing die cavity board and lower bolster for all contact surfaces of die cavity board and lower bolster have good uniformity, and the die cavity board is laminated well with all contact surfaces homoenergetic of lower bolster after the compound die, avoids the process of moulding plastics to produce plastics and spills over the overlap that leads to the tape measure button. (2) The utility model discloses a tape measure button mould is split type structure with cope match-plate pattern and die cavity board design, is favorable to the user later stage to separately maintain cope match-plate pattern and die cavity board. (3) The utility model discloses a tape measure button mould sets up the backing plate under the lower bolster, reduces the deformation of lower bolster. (4) The utility model discloses a tape measure button mould will go up the return board and return the form that the needle board design is the difference of thickness down for go up return board and return the thickness of needle board and match with actual atress down, reduce the deformation of whole return board.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

As shown in fig. 1, the tape measure button mold of the present embodiment includes an upper mold plate 100, a cavity plate 200, a lower mold plate 300, a backing plate 400, a needle returning plate 500, a mold foot 600 and a base 700 arranged from top to bottom;

a backing plate 400 is arranged below the lower template 300, the backing plate 400 is dropped on the mold foot 600, and the mold foot 600 and the base 700 are fixed through bolts; the needle returning plate 500 is positioned between the two mold feet 600, and the needle returning plate 500 is used for installing the reset rod 800; the needle returning plate 500 comprises an upper needle returning plate 510 and a lower needle returning plate 520, wherein the thickness of the upper needle returning plate 510 is smaller than that of the lower needle returning plate 520;

the upper template 100 and the cavity plate 200 are split, and the design is beneficial for a user to separately maintain and maintain the upper template 100 and the cavity plate 200 after the mold is used for a period of time; the cavity plate 200 and the lower die plate 300 are processed by a linear cutting process, a die cavity is formed in the middle of the cavity plate 200 and the lower die plate 300 after being combined, and the linear cutting process belongs to one-step forming, so that all contact surfaces of the cavity plate 200 and the lower die plate 300 have good consistency, all contact surfaces of the cavity plate 200 and the lower die plate 300 can be well attached after die assembly, and therefore the phenomenon that plastic overflows in the injection molding process to cause flash of the tape button 900 can be avoided, and the production speed of the tape button 900 can also be improved.

When the tape measure button mould of the embodiment is installed, the mould foot 600 is tightly leaned against the plate of the injection moulding machine, and the whole mould is kept stable by utilizing the fixed connection relationship between the mould foot 600 and the base 700.

Although the embodiments of the present invention have been described in the specification, these embodiments are only for the purpose of presentation and should not be construed as limiting the scope of the present invention. Various omissions, substitutions, and changes may be made without departing from the spirit and scope of the invention.
