Description

Date stamp

【Technical field】

The present invention relates to a kind of date stamps, and in particular to a kind of date stamp in mold.

【Background technology】

At present, for managing for stringent enterprise, each important plastic parts will labeling production date, after determining Phase repairs or date of retirement.If Fig. 1 is schematically shown as the structure sectional view of prior art mold date stamp, number 11 and pointer 12 are done For overall applicability in a mold, however, the die date stamp rotational time has been grown and will have been slided, the date for causing locking is unstable It is fixed, so cause product in volume production can not management and control, production efficiency will be substantially reduced.In addition, for some with design requirement Plastic cement products, when especially needing the plastic cement products material to add the design of glass 50% or so, the mold temperature generally required compares Height, as soon as when mould temperature raises, date stamp is easily stuck, thus it is easy to slip teeth when adjusting date stamp, mold is caused to need to dismantle again Repair.

In view of this, when being caused it is really necessary to provide a kind of date stamp with solving the above-mentioned easy slip of date stamp usage time length Between it is inaccurate and apply the problem of frequent detachable maintaining is needed in die material.

【The content of the invention】

It is asked it is therefore an object of the present invention to provide a kind of date stamp with solving above-mentioned existing date stamp to what production was brought Topic.

In order to achieve the above object, date stamp provided by the invention, be applied to mold in, the mold include male template, Number is carved in caster, male die core, mother module core, upper plate and lower roof plate, the upper end of the male die core, which includes：

Thimble is arranged in the male template and male die core, which opens up an aperture, the lower end of the thimble In the upper plate, pointer is carved in the upper end of the thimble, which coordinates to specify the day of the date stamp with the number Phase.

Preferably, the date stamp further includes a regulating rod, which is in cylindrical type, and in die sinking, which inserts Enter the aperture and adjust the direction of pointer to rotate the thimble.

Preferably, the aperture is located in the male die core.

Preferably, the thimble and the male die core close-fitting, the thimble and the male template empty avoiding.

Preferably, the distance that the thimble ejects upwards is more than the aperture to the distance of the thimble upper end.

Preferably, the digital and thimble upper end pointer of the male die core upper end is convex quarter or is intaglio.

Preferably, the lower end of the thimble by countersunk head be arranged on the upper plate in, the countersunk head of the thimble with it is described on Sealing ring is equipped between top plate.

Preferably, the distance of the aperture to the thimble upper end is more than 10mm.

Preferably, a diameter of 1.5mm of the aperture, a diameter of 1mm of the regulating rod.

Compared to the prior art, date stamp of the present invention is by the number that is engraved on the male die core and is engraved on the thimble Pointer is formed, and when needing to adjust pointer, injection molding machine mandril is ejected the thimble by the upper plate and lower roof plate, uses institute The aperture for stating the regulating rod insertion thimble gently rotates the thimble, and pointer is directed toward required number and completes the date stamp The adjusting on date.Date stamp of simple structure and strong practicability of the present invention, long lifespan are hardly damaged, under the high temperature conditions use when without Mold need to be dismantled to carry out maintenance.

【Description of the drawings】

Fig. 1 is schematically shown as the structure sectional view of prior art mold date stamp.

Fig. 2 is schematically shown as the structure sectional view of date stamp of the present invention.

Fig. 3 is schematically shown as date stamp of the present invention in the structure diagram of mold clamping state.

Fig. 4 is schematically shown as date stamp of the present invention in the structure diagram of mold die opening state.

【Specific embodiment】

The specific embodiment of the present invention is described in further detail below in conjunction with attached drawing.

It refers to Fig. 2 and Fig. 3 is illustrated, date stamp provided by the invention is applied in mold, which includes male template 200th, caster 300, male die core 210, mother module core 310, upper plate 400 and lower roof plate 500, the upper end of the male die core 210 are carved with Number 211, which includes：

Thimble 100 is arranged in the male template 200 and male die core 210, which opens up an aperture 110, the lower end of the thimble 100 is arranged in the upper plate 400, and pointer 111 is carved in the upper end of the thimble 100, the pointer 111 with Digital 211 cooperation is with the date of the specified date stamp.

Wherein, the date stamp further includes a regulating rod（It is not shown in figure）, the regulating rod（It is not shown in figure）In cylinder Type, in die sinking, the regulating rod（It is not shown in figure）It is inserted into the aperture 110 and adjusts pointer to rotate the thimble 100 111 direction.

Wherein, the aperture 110 is located in the male die core 210.

Wherein, the thimble 100 and 210 close-fitting of male die core, the thimble 100 and 200 empty avoiding of male template.

Wherein, the distance S1 that the thimble 100 ejects upwards be more than the aperture 110 to 100 upper end of thimble away from From S2, and S2 is more than 10mm.

Wherein, the pointer 111 of the number 211 of 210 upper end of male die core and 100 upper end of thimble be convex quarter or It is intaglio.

Wherein, the lower end of the thimble 100 is arranged on by countersunk head 120 in the upper plate 400, and the thimble 100 sinks Sealing ring 600 is equipped between first 120 and the upper plate 400.

Wherein, a diameter of 1.5mm of the aperture 110, a diameter of 1mm of the regulating rod.

In this present embodiment, the pointer 111 of date stamp and number 211 are engraved in respectively on thimble 100 and male die core 210, institute The pointer 111 stated and number 211 is convex respectively is engraved on the thimble 100 and male die core 210, in forming plastic cement product, pointer 111 and digital 211 coordinate the date of manufacture for specifying plastic cement products, if necessary to adjust the date of date stamp, refer to Fig. 4 and paint Show, after the thimble 100 is ejected by the upper plate 400 and lower roof plate 500 by the mandril of injection molding machine, inserted using regulating rod Into the rotation gently of aperture 110 of thimble 100, days of needs is assigned to so as to which the pointer 111 on thimble 100 be driven to be rotated up Phase.

The date stamp of the present invention avoids date stamp for a long time using easy to slip teeth by the fastening effect of sealing ring 600 Problem.Especially date stamp of the present invention easily occurs stuck without revolvable phenomenon under the high temperature conditions, and the present invention is by by the date Chapter makes two parts so as to avoid that need to dismantle the problem of mold could carry out maintenance date stamp respectively, meanwhile, the present invention The of simple structure and strong practicability of date stamp, long lifespan are hardly damaged.

It is noted that the invention is not restricted to the above embodiment, any person skilled in the art is based on this hair Any simple modification, equivalent change and modification that bright technical solution makees above-described embodiment both falls within the protection model of the present invention In enclosing.
