Definitions

  • the invention relates to an inkpad holder for arrangement in an insertion compartment of a self-inking stamp, having a bottom and walls projecting therefrom which delimit a receiving space for receiving an inkpad, at least one wall of the inkpad holder comprising a retaining web protruding into the receiving space in order to retain the inkpad.
  • the invention relates to a device for injection moulding such an inkpad holder, having an injection mould tool comprising a first and a second tool part, which injection mould tool encloses a mould cavity in a closing position, the first and second tool parts being movably supported relative to one another in an opening or closing direction.
  • the invention relates to a method for producing such an inkpad holder in an injection moulding process.
  • a self-inking stamp in which an inkpad holder is inserted like a drawer in an insertion compartment of the stamp housing is known e.g. from EP 1 603 755 B1.
  • the inkpad container can be removed from the insertion compartment and replaced by a new inkpad container or the original inkpad container with refilled inkpad.
  • the insertion compartment comprises a freely accessible insertion opening on at least one side.
  • the inkpad is glued into the inkpad holder.
  • this may result in the formation of threads in the corners.
  • a self-inking stamp in which a replaceable inkpad container comprises inwardly protruding ledge projections on the bottom side.
  • an inkpad holder of the above given type is to be provided, by which the inkpad is reliably held in the intended position within the receiving space.
  • a simplified method and a device for the manufacture of such an inkpad holder shall be indicated.
  • the inkpad holder of the above given kind is characterized in that the retaining web extends over the entire length of the wall.
  • This design has the advantage that the retaining web extends into the corner zones of the inkpad holder. Thus, it may be ensured in a reliable manner that any formation of threads or any bulging of the inkpad does not lead to any protrusion of the inkpad on the upper side of the inkpad holder.
  • the retaining web is provided on an edge portion of the wall, the edge portion facing away from the bottom. During assembly, the inkpad is pressed below the retaining web projecting to the inside on the upper edge portion of the wall, the inkpad being fixed thereby in the receiving space.
  • the inkpad holder can advantageously have the same overall height as conventional embodiments without any retaining web. In addition, this may ensure a safer hold of the inkpad in the receiving space.
  • the wall is provided with the retaining web on a longitudinal side of the inkpad holder.
  • the inkpad holder therefore comprises longitudinal sides and narrow sides, the retaining web being provided on one of the longitudinal sides.
  • the inkpad holder preferably comprises an essentially rectangular bottom, on the longitudinal or transverse edges of which the walls are angled. Adapting the retaining web on a longitudinal side of the inkpad holder ensures that the inkpad is sufficiently pressed toward the bottom of the inkpad holder in order to hold the inkpad in the intended position.
  • the fixation of the inkpad in the inkpad holder may further be reinforced if at least two walls comprise retaining webs preferably on the longitudinal sides.
  • the inkpad holder only comprises retaining webs on the two longitudinal sides but not on the narrow sides.
  • the inkpad holder comprises retaining webs on both the longitudinal and the narrow sides.
  • the retaining web is 0.8 to 2.5 mm, in particular 0.9 to 1.3 mm, preferably substantially 1 mm in width.
  • the width relates to the extension of the retaining web away from the pertinent wall of the inkpad holder.
  • the retaining web be integral with the wall.
  • the bottom, the walls and the at least one retaining web are designed integrally, in particular as injection moulding part.
  • the object of the invention is obtained by a device of the above mentioned kind, in which the injection mould tool comprises at least one slide part extending over the entire length of the mould cavity, which slide part is movably arranged between an injection position engaging behind the retaining web of the inkpad holder and a separating position releasing the retaining web in a direction deviating from the opening or closing direction of the tool parts.
  • the injection mould tool is arranged in the closing position, in which the shape of the inkpad holder is formed by the mould cavity.
  • the slide part is arranged in the injection position, in which the slide part is arranged in portions below an area of the mould cavity forming the retaining web.
  • the slide part is preferably arranged in the injection position such that the slide part leaves an area of the mould cavity blank, the area being essentially U-shaped in cross-section, to form the wall with the retaining web and the edge portion of the bottom.
  • the slide part By transferring the slide part transverse to the closing or opening direction of the injection mould tool and away from the wall of the inkpad holder, which comprises the retaining web, to the separating position the slide part can be detached from the engagement with the retaining web, so that upon termination of the injection moulding process the injection mould tool can be opened in an opening direction to remove the finished inkpad holder from the injection mould tool.
  • the slide part is movable at least over the width of the retaining web in order to be transferred into the separating position, a safety distance exceeding the width of the retaining web being preferably covered in order to reliably prevent the injection mould tool from being blocked by the slide part when separating the tool parts in the opening direction.
  • At least one ejector for removing the inkpad holder from the mould cavity is provided on one of the tool parts, the at least one slide part being different from the ejector. Accordingly, separate components are provided as slide part and ejector, so that movement of the slide part for the release of the retaining web of the inkpad holder can be effected independently of removing the inkpad holder from the mould cavity.
  • Said embodiment has the advantage of that the inkpad holder is present in the mould cavity in a fixed manner, if the at least one slide part is moved away from the longitudinal side of the mould cavity for the demoulding process. Thus, it is prevented that he inkpad holder sticks to one of the slide parts and is carried along by this slide part.
  • the two slide parts are movable in opposite directions for releasing the retaining webs, with the movement of the one slide part preferably being coupled to that of the other slide part.
  • the first tool part and the second tool part are jointly slidable between the injection position and the separating position by a predetermined distance in the opening or closing direction, the injection mould tool comprising corresponding guide means, by which the joint shifting of the tool parts in the opening or closing direction can be converted into the movement of the slide part between the injection position and separating position. Accordingly, shifting the tool parts along the predetermined distance in the opening direction is coupled to the movement of the slide part into the separating position.
  • the guide means comprise guide surfaces arranged diagonally to the opening or closing direction, in particular at an angle between 6° and 20°.
  • the inclination of the guide surfaces can determine the translation between the shift of the tool parts and the movement of the slide part.
  • the one guide surface is provided on the slide part and the other guide surface is preferably formed on the front end of an injection nozzle.
  • the front end of the injection nozzle preferably converges in a conical manner. In the transfer between the injection position and the separating position the guide surfaces of the slide part and the injection nozzle slide alongside each other.
  • the guide means comprise a spring or traction force element causing the slide part to be moved into the separating position.
  • spring elements or core pullers may be provided to shift the slide part into the separating position.
  • the injection mould tool comprises a stop for limiting the shift of the first tool part in the opening direction, in which context the second tool part for separating the tool parts is movable relative to the first tool part which has been shifted into the stop position. Accordingly, the injection mould tool can be moved from the closing position for injection moulding of the inkpad holder in the opening direction via the stop position of the first tool part, which corresponds to the separating or releasing position of the slide part, into the open position for the removal of the inkpad holder.
  • demoulding can be achieved thereby in a single movement process.
  • the first tool part is connected to a spring element, which biases the first tool part in the direction of the stop position corresponding to the separating position. Having reached the stop position of the first tool part, the second tool part can be shifted into the open position, with the first tool part being stationary.
  • the second tool part is connected to a drive, in particular a hydraulic drive.
  • the object on which the present invention is based is obtained by a method in which the retaining web is engaged behind in an injection position by a slide part extending over the entire length of the wall, which slide part is then shifted to a separating position releasing the retaining web.
  • FIG. 1 shows as sectional view of a self-inking stamp, in which a conventional inkpad holder is arranged in an insertion compartment;
  • FIG. 2 a shows a view of an inkpad holder, in which support projections are provided on the longitudinal sides, which however do not extend up to the corner zones;

  • FIG. 1 shows a conventional self-inking stamp 1 comprising a frame-shaped stamp housing 2 (hereinafter called housing 2 ).
  • the housing 2 comprises an insertion compartment 3 for an inkpad holder 4 arranged therein for replacement, in which an inkpad 5 is received.
  • a paper clip 16 is used for the replacement of the inkpad holder 4 , which paper clip engages with a recess 15 of the inkpad holder 4 .
  • the insertion compartment 3 may be open to both sides, so that the inkpad holder 4 can be pressed out of the insertion compartment 3 without any recess 15 .
  • a stamp unit 6 is arranged inside the housing 2 , which comprises a stamp plate 7 which includes stamp types and is arranged on a stamp plate carrier 7 ′.
  • the stamp unit 6 is shown in an inking position adjacent to the inkpad 5 .
  • an actuating arm 8 is provided, which is placed on the housing 2 like a hood in the shown example.
  • the actuating arm 8 comprises legs (not shown) on the narrow sides, which are inserted in suitable guides on the narrow side walls of the housing 2 and guided therein in a slidable manner.
  • a spring 11 acts between the actuating arm 8 and the housing 2 , which holds the actuating arm 8 in its upper position shown and thus the stamp unit 6 in the inking position.
  • the shift of the actuating arm 8 into its lower end or actuating position is transmitted via a turning mechanism 12 in a manner known per se, which mechanism causes the stamp unit 6 to be swivelled from the shown inking position and into a printing position provided for printing a printing surface as well as at the same time a descending movement.
  • the stamp plate 7 projects with the stamp types through a bottom aperture 13 of the housing 2 , so that a printing can be made on a printing surface.
  • the turning mechanism 12 comprises a curve control or slot guidance known in the prior art, so as to turn the stamp unit 6 into the printing position by 180° upon actuation of the actuating arm 8 .
  • the inkpad 5 is held by means of an adhesive joint in the inkpad holder 4 .
  • an inkpad holder 4 according to FIG. 2 a has been known, in which support projections 14 ′ are provided on the longitudinal sides, by means of which the inkpad 5 should be fixed in the inkpad holder 4 .
  • the support projections 14 ′ do not extend into the corner zones of the inkpad holder 4 .
  • FIGS. 2 b to 2 d schematically illustrate the production of the known inkpad holder 4 in an injection mould tool 100 comprising a first tool part 101 and a second tool part 102 .
  • the injection mould tool is arranged in a closing position enclosing a mould cavity, in which closing position the inkpad holder 4 is produced by injection moulding.
  • the second tool part 102 of the injection mould tool 100 comprises two ejectors 103 whose front ends engage behind the free spaces for the support projections 14 ′ during the injection moulding process.
  • the second tool part 102 is moved away from the first tool part 101 in the opening direction 104 (cf. FIG. 2 c ).
  • the ejectors 103 are shifted into the opening direction (cf. FIG. 2 d ). Due to the transverse position of the ejectors 103 relative to the opening direction 104 the front ends of the ejectors 103 are shifted to the inside upon opening of the injection mould tool 100 , thus releasing the support projections 14 ′. Accordingly, demoulding takes place only upon the ejection of the inkpad holder 4 . On the one hand, this method is complex. On the other hand, it is absolutely necessary that the support projections 14 ′ leave the corner zones of the inkpad holder 4 blank, since these fixed corners center the inkpad during demoulding and prevent shifting up to one of the two ejectors 103 . If in such an embodiment such corners were omitted, the pad holder might stick to one of the two opposed ejectors 103 and consequently demoulding could fail.
  • FIG. 3 shows an inkpad holder 4 which, just like the known embodiment according to FIG. 2 , comprises a bottom 15 including walls 16 and 17 protruding therefrom on the longitudinal or narrow sides. According to FIG. 3 two retaining webs 14 extend over the entire length of the opposite longitudinal walls 16 of the inkpad holder 4 .
