For the convenience of explaining the reason for the reduction of the flow lines of the cover plate body 203, the knob cover plate mold 2 according to the embodiment of the present invention is described below, and the reason for the reduction of the flow lines of the appearance surface of the cover plate body 203 is explained in principle in conjunction with the structure of the knob cover plate mold 2.
As shown in fig. 4 to 5, a knob cover plate mold 2 for molding a knob cover plate 20 of a laundry treating apparatus according to an embodiment of the present invention includes: the knob covers the core 21.
The knob cover plate mold insert 21 has a knob cover plate cavity, the knob cover plate includes a cover plate body cavity 213 and a plurality of cover plate connecting rib cavities 214, a side wall surface of the thickness direction of the cover plate body cavity 213 is used for forming an appearance surface of the cover plate body 203, and the cover plate connecting rib cavities 214 are located at the other side wall surface of the thickness direction of the cover plate body cavity 213 and are communicated with the cover plate body cavity 213. The knob cover plate mold insert 21 has a cover plate gate located at the peripheral wall of the cover plate body cavity 213, and/or the knob cover plate mold insert 21 has a cover plate gate located at the center of the other side wall surface in the thickness direction of the cover plate body cavity 213.
In a plane parallel to the cover plate body cavity 213, a connecting line of a projection of the center of the cover plate gate and a projection of the center of the cover plate connecting rib cavity 214 is L1 ', the width direction of the cover plate connecting rib cavity 214 is L2', and an included angle between L1 'and L2' ranges from 80 degrees to 100 degrees. For example, the included angle of L1 'and L2' is 81 °, 82 °, 83 °, 84 °, 85 °, 86 °, 87 °, 88 °, 89, ° 90 °, 91 °, 92 °, 93 °, 94 °, 95 °, 96 °, 97 °, 98 °, or 99 °.
Specifically, during injection molding, in the material flowing process, hotter melt material enters the knob cover plate mold 2 through the cover plate gate, and contacts with the wall surface of the relatively cold knob cover plate cavity in the flowing process, so that the material can be rapidly frozen on the surface of the wall surface of the knob cover plate cavity to form a relatively thin solidified layer. The flow direction of the metal particles in the solidified layer determines the quality of the appearance of the spray-free product, and stable flow can form consistent metal particle orientation to obtain better appearance. However, when the cover plate body cavity 213 is communicated with the cover plate connecting rib cavity 214, when a material flows through the communicating position between the cover plate connecting rib cavity 214 and the cover plate body cavity 213, the material flow direction is divided into two parts, one part of the material continuously flows in the cover plate body cavity 213 along the original flow direction, the other part of the material flows to the cover plate connecting rib cavity 214, the material flowing into the cover plate connecting rib cavity 214 flows back into the cover plate body cavity 213 from the cover plate connecting rib cavity 214, an unstable flow field is formed near the root of the cover plate connecting rib cavity 214 under the continuous flow of the subsequent melt material, and under the continuous action of the fluid pressure, the solidified layer of the appearance surface at the corresponding position of the cover plate body cavity 213 to the cover plate connecting rib cavity 214 is damaged, so that the orientation of the metal particles in the solidified layer in the area is disordered, and the solidified layer is a flow mark when the appearance surface is shown.
In particular, in a manner that the material flow direction is substantially the same as the width direction of the cover plate bead cavities 214, since the width of the cover web cavity 214 is greater than the thickness of the cover web cavity 214, in the width direction of the cover plate connecting rib cavity 214, the material enters the cover plate connecting rib cavity 214 and flows back to the cover plate body cavity 213 from the cover plate connecting rib 204 under the condition that the cover plate connecting rib cavity 214 is not filled, while the material in the rest position of the cover plate body cavity 213 may enter the cover plate connecting rib cavity 214 again and then flow back again, in other words, when the material flows along the width direction of the cover plate connecting rib cavity 214, there is a case where the material flows back from the cover plate bead cavity 214 to the cover plate body cavity 213 many times, the solidified layer at the communication position of the cover plate connecting rib cavity 214 and the cover plate body cavity 203 is seriously damaged, and then the flow lines at the position of the cover plate body 203 corresponding to the cover plate connecting rib 204 are serious.
In the present application, because a connection line between the projection of the center of the cover plate gate and the projection of the center of the cover plate connecting rib cavity 214 in a plane parallel to the cover plate body cavity 213 is L1 ', the width direction of the cover plate connecting rib cavity 214 is L2', and the included angle between L1 'and L2' ranges from 80 ° to 100 °, the material flows in a diverging manner after flowing out from the cover plate gate, which is beneficial to the material flowing along the thickness direction of the cover plate connecting rib cavity 214, thereby reducing the number of times that the material flows back from the cover plate connecting rib cavity 214 to the cover plate body cavity 213, reducing the flow lines on the cover plate body 203 at least to a certain extent, improving the yield of the cover plate body 203 at least to a certain extent, reducing the cost, and meeting the use requirements of users.
According to the knob cover mold 2 for molding the knob cover 20 of the laundry treating apparatus of the embodiment of the present invention, because the connecting line of the projection of the center of the cover plate gate and the projection of the center of the cover plate connecting rib cavity 214 in the plane parallel to the cover plate body cavity 213 is L1 ', the width direction of the cover plate connecting rib cavity 214 is L2', the included angle between L1 'and L2' ranges from 80 degrees to 100 degrees, since the material flows in a diverging manner after flowing out of the cover plate gate, the material is facilitated to flow along the thickness direction of the cover plate connecting rib cavities 214, thereby helping to reduce the number of times that the material flows back from the cover plate connecting rib cavity 214 to the cover plate body cavity 213, thereby be favorable to reducing the flow line on the apron body 203 to a certain extent at least, improve the yield of apron body 203 to a certain extent at least, reduce cost satisfies user's user demand.
According to the utility model discloses clothing treatment facility's knob apron 20, in the plane that is on a parallel with apron body 203, the line of the projection at the center of apron runner molding area 2031 and the projection at the center of apron splice bar 204 is L1, the width direction of apron splice bar 204 is L2, the value range of the contained angle of L1 and L2 is 80 ~ 100, be favorable to reducing the flow line on the apron body 203 at least to a certain extent, improve the yield of apron body 203 to a certain extent at least, and therefore, the cost is reduced, and the user demand is met.
In some embodiments of the present invention, as shown in fig. 3, the cover connection rib 204 includes: the cover plate connecting rib body 2041 and the cover plate connecting portion 2042, the cover plate connecting portion 2042 is connected between the cover plate connecting rib body 2041 and the cover plate body 203. Specifically, in the knob cover plate mold 2, as shown in fig. 5 to 6, the cover plate connecting rib cavity 214 includes a cover plate connecting rib body cavity 2141 and a cover plate connecting portion cavity 2142, and the cover plate connecting portion cavity 2142 is communicated between the cover plate connecting rib body cavity 2141 and the cover plate body cavity 213. Thus, the structure is simple.
Alternatively, as shown in fig. 3, the thickness of the cover connecting portion 2042 is smaller than that of the end of the cover connecting rib body 2041 connected to the cover connecting portion 2042. Specifically, in the knob cover plate mold 2, as shown in fig. 5, the thickness of the cover plate connecting portion cavity 2142 is smaller than the thickness of the end of the cover plate connecting rib body cavity 2141, which is communicated with the cover plate connecting portion cavity 2142, when injection molding is performed, since the wall surface of the cover plate connecting rib cavity 214 does not have a cover plate gate, when a material flows in the cavity, the material may first flow through the cover plate body cavity 213 and flow through the cover plate body cavity 213 to the cover plate connecting rib cavity 214, and by making the thickness of the cover plate connecting portion cavity 2142 smaller than the thickness of the cover plate connecting rib body cavity 2141, the flow area and the number of times of backflow of the material from the cover plate connecting rib cavity 214 to the cover plate body cavity 213 may be reduced, thereby further preventing an unstable flow field from being formed at the communication position between the cover plate connecting rib cavity 214 and the cover plate body cavity 213, and further preventing the material of the cover plate connecting rib body cavity 2141 from flowing back through the cover plate connecting portion cavity 2142 to the body cavity 213 and causing material intersection Thereby avoiding the flow pattern problem generated at the connection part of the cover body 203 and the cover connection rib 204.
Optionally, the thickness of the cover connecting portion 2042 is smaller than the thickness of the cover connecting rib body 2041. From this, can reduce the flow area and the backward flow number of times that the material flows back to apron body cavity 213 from apron splice bar cavity 214, can further avoid forming unstable flow field in the intercommunication department of apron splice bar cavity 214 and apron body cavity 213, further avoid the material of apron splice bar body cavity 2141 to flow back to apron body cavity 213 and the material that leads to intersects through apron splice bar cavity 2142, thereby avoid the flow line problem that produces in the department of connecting with apron splice bar 204 of apron body 203.
Alternatively, a part of the surface of the cover connecting portion 2042 facing the cover body 203 is recessed toward a direction away from the cover body 203 to form a cover penetration hole that penetrates the cover connecting portion 2042 in the thickness direction of the cover connecting portion 2042. Specifically, when corresponding to the knob cover plate mold 2, the cover plate connecting portion cavity 2142 is provided with a cover plate pillar structure for molding the cover plate through hole, and the cover plate pillar structure extends in the entire thickness direction of the cover plate connecting portion cavity 2142. Like this, because apron splice bar die cavity 214 does not have the apron runner, when the material flows in the die cavity of knob apron mould 2, can at first flow through apron body die cavity 213, flow to apron splice bar die cavity 214 behind apron body die cavity 213, and through setting up the apron stand structure, the circulation area that the material flows back to apron body die cavity 213 from apron splice bar die cavity 214 can be reduced to the lid stand structure, can further avoid forming unstable flow field at the intercommunication department of apron splice bar die cavity 214 with apron body die cavity 213, further avoid the material intersection that the material of apron splice bar body die cavity 2141 flows back to apron body die cavity 213 and leads to through apron splice bar die cavity 2142, thereby avoid the flow line problem that produces at the department of apron body 203 that links to each other with apron splice bar 204.
