  Therefore, the grooves 141uL, 142uL, 141dL, 142dL, 141uR, 142uR, 141dR and 142dR do not intersect with each other.

  An embodiment in which all or part of the grooves 141uL, 142uL, 141dL, 142dL, 141uR, 142uR, 141dR and 142dR intersect each other is also conceivable.

  Since the grooves 141uL, 142uL, 141dL, 142dL, 141uR, 142uR, 141dR and 142dR disperse the load force caused by the weight of the air conditioning outdoor unit 1 also in a direction other than the vertical direction, It has the effect of improving the strength.

  Such an effect is remarkable in the configuration in which the weight of the outdoor unit stand for the air conditioning is suppressed as described above by making the thickness of the constituent elements and the like smaller in consideration of the lightness, and the strength is improved. An ideal outdoor unit stand 100 for air conditioning is realized that is less likely to be sacrificed.

  6A is a front view of the core mold 1100 used for manufacturing the outdoor unit stand 100 for air conditioning of the embodiment of the present invention, and FIG. 6B is a front view of the present invention. FIG. 6C is a bottom view of a core mold 1100 used for manufacturing the air conditioning outdoor unit stand 100, and FIG. 6C is a manufacturing view of the air conditioning outdoor unit stand 100 according to the embodiment of the present invention. FIG. 3 is a right side view of a core mold 1100 used for the above.

  A mold surface corresponding to the shape of the inner wall of the air conditioner outdoor unit stand 100 provided with the uneven structure 140 is formed on the outer wall of the core mold 1100.

  A more specific description is as follows.

  The core mold surface 1150 is a core mold surface corresponding to the shape of the lower wall portion of the hem portion 150.

  The core die surface 1160 is a core die surface corresponding to the shape of the inner wall portion of the transition portion 160.

  The core die surfaces 1110L and 1110R are core die surfaces corresponding to the shapes of the inner wall portions of the upper surfaces 110L and 110R, respectively.

  The core mold surfaces 1121L, 1122L, 1123L, 1121R, 1122R and 1123R are core mold surfaces corresponding to the shapes of the inner wall portions of the side surfaces 121L, 122L, 123L, 121R, 122R and 123R, respectively.

  By using such a core mold 1100, the shape of the inner wall portion of the air conditioner outdoor unit stand 100 provided with the uneven structure 140 can be formed with high accuracy.

  Similarly, the concavo-convex structure 130 is provided by using a cavity mold in which a mold surface corresponding to the shape of the outer wall of the air conditioner outdoor unit stand 100 provided with the concavo-convex structure 130 is formed on the inner wall. The shape of the inner wall portion of the existing outdoor unit stand 100 for air conditioning can be formed with high accuracy.

  As will be apparent from the description below, the presence of the concavo-convex structure 140 may cause the mold release defect of the core mold 1100, and the concavo-convex structure 130 may cause the mold release defect of the cavity mold. ,rare.

  Here, referring mainly to FIG. 5, a specific description will be given of the triangular shape of the ridges 131uL, 132uL, 133uL, 131dL, 132dL, 133dL, 131uR, 132uR, 133uR, 131dR, 132dR, and 133dR having a vertical cross section. Explained.

  At the same time, the fact that the presence of the concavo-convex structure 130 hardly causes the mold release failure of the cavity mold will be specifically described.

  Now, the length a of the upper side of the triangle is larger than the length b of the lower side of the triangle.

  The height h of the ridges 131uL, 132uL, 133uL, 131dL, 132dL, 133dL, 131uR, 132uR, 133uR, 131dR, 132dR, and 133dR based on the side surfaces 121L, 122L, 123L, 121R, 122R, and 123R is a predetermined value. It does not exceed the value h0. The predetermined value h0 is, for example, about 0.2 mm, which enables good die molding.

  The significance of such dimensional design is as follows.

  That is, when the cavity mold is released in the direction of the arrow X, the interference with the cavity mold cannot occur on the upper side of the triangle, but the interference with the cavity mold can occur on the lower side of the triangle. There is.

  However, since the mold release of the cavity mold is performed when the temperature of the thermoplastic resin is relatively high, the concavo-convex structure 130 has some elasticity.

  Since the length a of the upper side of the triangle is larger than the length b of the lower side of the triangle, the length b is not so large and the height h does not exceed the predetermined value h0.

  Therefore, interference with the cavity mold may occur on the lower side of the triangle, but since the adverse effect of such interference is extremely small, there is almost no risk of defective release of the cavity mold.

  By the way, in the embodiments described above, the outer wall portions of the side surfaces 121L, 122L, 123L, 121R, 122R, and 123R have projections that extend in the lateral direction of the side surfaces 121L, 122L, 123L, 121R, 122R, and 123R. The uneven structure having the shape of was provided.

  However, the present invention is not limited to this, and an uneven structure having a groove shape extending in the lateral direction of the side surfaces 121L, 122L, 123L, 121R, 122R, and 123R is formed on the outer wall portions of the side surfaces 121L, 122L, 123L, 121R, 122R, and 123R. It may be provided.

  Therefore, with reference mainly to FIG. 7, an air conditioning outdoor unit stand 100 of such another embodiment will be specifically described.

  FIG. 7 is a schematic vertical partial cross-sectional view of the outdoor unit for air-conditioning unit 100 according to another embodiment of the present invention.

  FIG. 7 shows a partial cross section in the vicinity of the side surface 121L in which the cross-section normal direction is the left-right direction.

  In FIG. 7, in order to make it easier to understand the configuration of such a partial cross section, the illustration of details is simplified. For example, the illustration of the chamfered structure at the ridgeline portion of the uneven structure 230 is omitted.

  On the outer wall portion of the side surface 121L, an uneven structure 230 having the shapes of grooves 231uL and 231dL extending in the lateral direction of the side surface 121L is provided. The concavo-convex structure 230 is an example of the concavo-convex structure of the present invention, which is provided on at least one outer wall portion of the plurality of side surfaces and has the shape of a ridge or a groove extending in the lateral direction of the side surfaces.

  The longitudinal cross section of each of the grooves 231uL and 231dL has a triangular shape.

  The triangular shapes of the cross sections of the grooves 231uL and 231dL in the vertical direction will be described in detail later.

  The groove 231uL is provided in a band shape in the central portion in the up-down direction in the upper half portion of the outer wall portion of the side surface 121L. The groove 231dL is provided in a band shape in the vertical center of the lower half of the outer wall of the side surface 121L.

  The inner wall portion of the side surface 121L is also provided with the uneven structure 240 having the shapes of the ridges 241uL and 241dL so that the thickness t of the side surface 121L is constant, corresponding to the uneven structure 230 provided on the outer wall portion. ing. The concavo-convex structure 240 is provided on at least one inner wall portion of the plurality of side surfaces so as to have a constant side surface thickness corresponding to the concavo-convex structure provided on the outer wall portion. It is an example of another uneven structure of the present invention having a shape.

  The ridge 241uL is provided in a band shape in the central portion in the up-down direction in the upper half portion of the inner wall portion of the side surface 121L. The ridge 241dL is provided in a strip shape in the vertical center of the lower half of the inner wall of the side surface 121L.

  Now, the length α of the upper side of the triangle is smaller than the length β of the lower side of the triangle.

  The depth δ of the grooves 231uL and 231dL based on the side surface 121L does not exceed the predetermined value δ0. The predetermined value δ0 is, for example, about 0.2 mm, which enables good die molding.

  The significance of such dimensional design is as follows.

  That is, when the cavity mold is released in the direction of the arrow X, the interference with the cavity mold is unlikely to occur on the lower side of the triangle, but the interference with the cavity mold is likely to occur on the upper side of the triangle. There is.

  However, since the mold release of the cavity mold is performed when the temperature of the thermoplastic resin is relatively high, the concavo-convex structure 230 has some elasticity.

  Since the length α of the upper side of the triangle is smaller than the length β of the lower side of the triangle, the length α is not so large and the depth δ does not exceed the predetermined value δ0.

  Therefore, interference with the cavity mold may occur on the upper side of the triangle, but since the adverse effect of such interference is extremely small, there is almost no risk of defective release of the cavity mold.

  In order to confirm that the air conditioner outdoor unit stand 100 described in detail so far has excellent strength, a product compression test was performed.

  The test method of the compression test is as follows.

  A compression jig having 40 mm × 40 mm number of compression surfaces and a compression surface center-to-center distance of 250 mm is used, and compression is performed until the sample breaks or the load reaches 5 kilonewtons. And the amount of deflection when a load of 0.98 to 4.90 kilonewtons was applied was measured.

  Regarding the details of the sample and the test piece, the shape of the test piece is a product, and the number of test pieces is 2.

  Regarding the details of the test, the test speed is 10 mm / min, the test temperature is 23 degrees Celsius, the test device is a precision universal tester Autograph AG-100kND manufactured by Shimadzu Corporation, and the tester capacity is Is a load cell type 100 kilonewton.

  The test results of the compression test are as follows.

  When the applied load is 0.98 kilonewton, that is, 100 kilogram weight, the deflection amount of the first test piece is 2.78 millimeters, and the deflection amount of the second test piece is 2.83 millimeters. The value was 2.81 millimeters.

  When the applied load is 1.96 kilonewtons, that is, 200 kilogram weight, the deflection amount of the first test piece is 7.02 millimeters, the deflection amount of the second test piece is 7.06 millimeters, and the average of these is The value was 7.04 millimeters.

  When the applied load was 2.94 kilonewtons, that is, 300 kilogram weight, sample breakage occurred and the amount of deflection could not be measured.

  When the applied load was 3.92 kilonewtons, that is, 400 kilogram weight, sample breakage occurred and the amount of deflection could not be measured.

  When the applied load was 4.90 kilonewtons, that is, 500 kilogram weight, sample breakage occurred and the amount of deflection could not be measured.

  For the first test piece, the maximum load applied until the sample fracture occurred was 2.73 kilonewtons.

  For the second test piece, the maximum load applied until the sample fracture occurred was 2.66 kilonewtons.

  Thus, it was confirmed that the outdoor unit stand 100 for air conditioning has excellent strength that passes the load resistance test of 250 kg.

  The outdoor unit stand for air conditioning in the present invention can reduce the risk that strength is sacrificed due to importance placed on lightness, and an outdoor unit for air conditioning such as an air conditioner or a heater is placed. It is useful for the purpose of using it as an outdoor unit stand for air conditioning.
