Definitions

  • the invention relates to an arrangement with a first component and with a second component, which is arranged slidingly movable in a receptacle of the first component, wherein the first component is produced by prototyping, in particular by injection molding, wherein the receptacle widening in the extension direction of the first component Entformungsabites has and a first guide portion in which the second component is guided along a guide axis.

  • a housing At least the first component, that is, for example, the housing is urgeformt and in particular by injection molding, further produced in particular by plastic injection molding.
  • the second component arranged so as to be slidably movable in the receptacle of the first component is guided as precisely as possible. This is especially true if several Components are provided, which are arranged so as to move in appropriate receptacles of the first component and adjacent to each other.
  • a guide section is provided according to the prior art, which serves to guide the first component. Furthermore, the known recording on a widening in the extension direction of the first component demolding section. Such a section can also be referred to as a draft angle.
  • Such a demolding section is necessary in order to be able to remove the first component produced by primary forming from the corresponding primary forming tool.
  • the inclination of these Entformungsabitese relative to the guide axis of the second component is relatively low. Nevertheless, even a slight inclination with a corresponding component length of the second component means that this can not be performed as precisely within the receptacle of the first component, as desired.
  • the object of the present invention is to refine an arrangement according to the prior art such that the most precise possible guidance of the first component in the second component is made possible.
  • This object is achieved in that the receptacle for guiding the second component has a second guide section spaced from the first guide section, wherein the demolding section is arranged between the first guide section and the second guide section.
  • the second component is guided not only at one end of the demolding section and freely movable at its other end, but also guided at this other end relative to the first component.
  • two bearings can be created in a simple manner along the guide axis. Since these bearings along the guide axis can be comparatively short, it is still possible to provide the demolding sections or bevels described above, so that a problem-free demolding of the first component in an injection molding process is possible.
  • At least one guide section can be polygonal in cross section. This means that the guide portion is suitable for second components, which are also polygonal on the cross-sectionally polygonal guide portion, for example. Square or rectangular.
  • At least one guide section is round in cross-section, in particular circular.
  • complementary sections of the second component which are round or circular in cross-section, be included within the lead section.
  • At least one guide section extends parallel or concentrically with the guide axis. It is advantageous if the two guide sections are parallel or concentric with each other. This allows the best possible guidance of the first component within the second component.
  • the demolding section along the guide axis is longer than one of the guide sections.
  • the longer the demoulding section the easier it is to demould the first component during production by prototyping.
  • the proportions are chosen so that the demolding section along the guide axis is longer than both guide sections together.
  • the guide sections themselves can be comparatively short, for example between one and five millimeters, while the demoulding section is comparatively long, for example between five and twenty-five millimeters.
  • the second component has surface sections complementary to the guide sections, wherein a step is formed between the surface sections, so that in the region of the demolding section of the receptacle between the first component and the second component creates a free space. Due to the free space, it is possible that the first component is guided along a lengthy displacement path precisely within the first component.
  • the invention further relates to a primary mold, in particular an injection mold, further in particular for producing a first component described above, with a cavity formed by the primary mold and with a slide which remains in the cavity during the primary molding to a cavity in the component to be manufactured and which is displaceable out of the cavity along a sliding axis after completion of the molding process, wherein the slider has a first slide portion which extends parallel or concentric with the slide axis, and to which a demolding section which expands in the extension direction of the slide adjoins.
  • Such a forming tool is, as already explained above, needed to be able to remove a manufactured using such a forming tool component in the field of recording.
  • the primary forming tool according to the invention provides that adjoining the demoulding section is a second slide section which extends parallel or concentrically with the slide axis.
  • This slider section causes a receptacle to be formed in the component, which forms a second guide portion which is adjacent to the demolding portion of the receptacle of the component.
  • Said slide can be connected to the cavity with a forming tool half or formed integrally therewith.
  • the slider is moved during demolding perpendicular to the parting plane of the master mold.
  • the slider is displaceable relative to the forming tool, it is also possible to demould components, for example housings, whose seats lie in undercut areas and thus can not be removed by merely separating the mold halves of the forming tool.

  • the first component 4 has a receptacle, generally designated by the reference numeral 8, which has an annular first guide section 10 at one end. Adjoining this guide section 10 is a demolding section 12, which widens in the direction of extension of the component 6 denoted by 14.

  • the inventive arrangement 2 illustrated in FIG. 2 also has a first component 4 and a second component 6 with a receptacle 8.
  • the guide portion 10 is not only annular, but cylindrical, so that a larger contact surface for the component 6 is created.

  • the component 6 has, adjacent to the first guide section 10, a first surface section 24, which is designed to be complementary to the first guide section 10. This means that for the described embodiment of the first surface portion is circular in cross section. The same applies to a second surface section 26, which is formed complementary to the second guide section 22. Thus, only a small clearance 18 or 28 occurs both in the region of the first guide section 10 and in the region of the second guide section 22. As a result, the guide is substantially improved over the arrangement known from the prior art.
  • This step creates a clearance 34 between the demolding section 12 of the receptacle 8 of the component 4 and the component 6 in the region of the demolding section 12.
