Abstract
Description
- 1. Technical Field
- The present disclosure relates to a housing, especially to a housing with a gradually varying thickness.
- 2. Description of Related Art
- Many electronic devices or plastic products often include a plastic housing with an opening. For example, a rectangular
plastic housing 10 of a Minus-Ion Air Purification Apparatus is shown inFIGS. 3 and 4 (related art). Thehousing 10 includes atop wall 104, foursidewalls 103 extending from thetop wall 104 and thefree ends 102 of the foursidewalls 103 forming an opening 101 opposite to thetop wall 104. The thickness of the foursidewalls 103 and thetop wall 104 is equal. - The
housing 10 is formed via Plastic Injection Molding Processing. The sprue gate (not shown) of the mold (not shown) is defined beside thetop wall 104, molten plastic is injected into the mold via the sprue gate and fill a rectangular cavity to form thehousing 10. The molten plastic runs from where thetop wall 104 is formed to where thesidewalls 103 are formed and is blocked at where thefree ends 102 of thesidewalls 103 is formed, namely where thefree end 102 of the eachsidewall 103 is formed is a filling-end. Because of the long filling route to form thesidewalls 103, pressure reduced at where thefree end 102 of thesidewalls 103 is formed is much greater than the another end near where thetop wall 104 is formed. The more pressure reduced, the more shrinkage, so the shrinkage deformation of thefree end 102 of thesidewall 103 is much greater than the end near thetop wall 104. Uneven shrinkage deformation of thesidewalls 103 leads to warping of thehousing 10. The warping of thehousing 10 will affect the assembly. - Therefore, what is needed is a housing with a gradually varying thickness to overcome the above mentioned limitations.
- Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is a schematic view of a housing with a gradually varying thickness in accordance with an exemplary embodiment. -
FIG. 2 is a cross-sectional view of the housing with a gradually varying thickness ofFIG. 1 , taken along line II-II. -
FIG. 3 is a schematic view of a housing in prior art. -
FIG. 4 is cross-sectional view of the housing ofFIG. 3 , taken along line IV-IV. - The disclosure including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
-
FIGS. 1 and 2 shows aplastic housing 100 of the disclosure. Theplastic housing 100 is formed via Plastic Injection Molding Processing. Thehousing 100 includes atop wall 11 and a plurality ofsidewalls 13 extending from thetop wall 11, eachsidewall 13 has afirst end 14 adjoining to thetop wall 11 and an oppositesecond end 15, thesidewalls 13 cooperatively define anopening 12 at thesecond ends 15 thereof. The distance between thetop wall 11 and theopening 12 is greater than the thickness of thesidewalls 13, namely the height of thehousing 100 is greater than the thickness of thesidewalls 13. - The
top wall 11 has a uniform thickness, and a thickness of eachsidewall 13 gradually decreases from thefirst end 14 to thesecond end 15. Eachsidewall 13 has a maximum thickness at thefirst end 14 thereof. - In this embodiment, the
top wall 11 of the housing is rectangular, and the number of thesidewalls 13 is four. The foursidewalls 13 have a same maximum thickness, minimum thickness and a same gradient rate of thickness from thefirst end 14 to thesecond end 15. - In other embodiment, the
sidewall 13 of thehousing 100 can also be cylindrical-shaped to form acylinder housing 100. Thehousing 100 includes around top wall 11 and acylindrical sidewall 13 extending from thetop wall 11, thesidewall 13 having afirst end 14 adjoining thetop wall 11 and an oppositesecond end 12, thesidewall 13 defining anopening 12 at thesecond end 15 thereof; thetop wall 11 has a uniform thickness, and a thickness of thesidewall 13 gradually decreases from thefirst end 14 to thesecond end 15. - Because of the long filling route to form the
sidewalls 13 in a plastic injection molding Process, pressure reduced at where thesecond end 15 of thesidewalls 13 is formed is much greater than thefirst end 14 of thesidewalls 13. The more pressure reduced, the more shrinkage rate, so the shrinkage rate of thesecond ends 15 of thesidewalls 13 is much greater than thefirst ends 14 of thesidewalls 13. The thickness of eachsidewall 13 is decreasing from thefirst end 14 to thesecond end 15, therefore, the shrinkage deformation of thesidewalls 13 can be even with the gradient thickness. The warping of the sidewalls is alleviated or is avoided. - It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the present disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
