Generally, appearance parts of home appliances such as a drum washing machine, for example, parts such as a control panel, a dispenser handle, etc., have both requirements of function and appearance.
Generally, most of appearance part manufacturing processes are injection molding and spraying processes, the sprayed appearance parts have gorgeous metal appearance effects, but the spraying processes have the defects of high pollution, high cost, low qualification rate, unrecyclable appearance parts after scrapping and the like, seriously affect the environment and the health of production personnel, and are not in accordance with the concept of green manufacturing. In order to overcome the defects of the spraying process, the spraying-free thermoplastic engineering material is produced at the right moment, and the spraying-free injection molding can give the metal appearance effect to the product, so that the spraying process is cancelled, the aim of reducing the production cost is fulfilled, and meanwhile, the emission of pollutants in the spraying process is avoided.
Whether the appearance part is manufactured by adopting the spraying-free material or the appearance part is manufactured by adopting the injection molding and spraying processes, for the material with poor flowability, particularly the spraying-free material containing metal particles, due to the fact that the spraying-free material contains the metal particles and other substances, the metal particles are unevenly distributed when the material is obstructed in the flowing process in the injection molding process, so that light scattering occurs under the irradiation of light when the product is injected, flow marks are formed on the product visually, the flow mark defect occurs on the product, and when the flow marks occur on the appearance surface of the product, the qualification rate of the product is low, and the use requirement of a user cannot be met. In the following description, a spray-free material containing metal particles is taken as an example, that is, the appearance member may be a spray-free member including a resin matrix and metal particles distributed in the resin matrix. Optionally, the metal particles are copper, aluminum or silver.
The exterior member, the home appliance, and the mold for molding the exterior member according to the embodiment of the present invention are described below. From this, the appearance part is the integrative injection moulding piece, and from this, the structure of an organic whole piece not only can guarantee the structure, the stability of performance of appearance part to convenient shaping, manufacturing are simple, have saved unnecessary assembly part and connection process moreover, guarantee the reliability that the appearance part is connected, and in addition, the bulk strength and the stability of the structure of integrative formation are higher, and it is more convenient to assemble, and the life-span is longer.
An exterior member according to an embodiment of the present invention includes: connecting plate and appearance board.
The surface of the connection plate is a non-exterior surface, that is, the surface of the connection plate is not exposed when the exterior member is used in the home appliance.
The appearance board extends along the circumference of connecting plate, and the one end of the width direction of appearance board links to each other with the periphery wall of connecting plate, and the one side surface in the thickness direction of appearance board is the outward appearance face. Here, one end of the appearance board in the width direction is an end connected to the connection board, and the other end of the appearance board in the width direction is an end distant from the connection board.
In some embodiments, a side surface in a thickness direction of the connecting plate is provided with at least one gate forming region adapted to correspond to a gate of the mold, the at least one gate forming region is provided adjacent to the appearance plate, and a wall thickness of the other end in a width direction of the appearance plate is smallest. Like this, can reduce the flow line of outward appearance board at least to a certain extent, prevent at least to a certain extent that the flow line from appearing in the outward appearance face of outward appearance board, improve the qualification rate of outward appearance part at least to a certain extent, reduce cost satisfies user's user demand.
In some embodiments, one end of the side surface of the appearance plate opposite to the appearance surface is provided with at least one gate forming area adjacent to the connecting plate, the gate forming area is suitable for corresponding to a gate of a mold, and the wall thickness of the other end of the appearance plate in the width direction is the smallest. Like this, can reduce the flow line of outward appearance board at least to a certain extent, prevent at least to a certain extent that the flow line from appearing in the outward appearance face of outward appearance board, improve the qualification rate of outward appearance part at least to a certain extent, reduce cost satisfies user's user demand.
Specifically, after the appearance part blank is injection-molded by the mold and is demoulded from the mold, a part of material at a gate of the mold is left on the appearance part blank and forms a gate forming part, and the gate forming area of the appearance part is the area where the gate forming part is located. It should be understood that the gate forming portion may be cut or partially cut off by reprocessing the appearance component blank, or the gate forming portion of the appearance component blank may not be processed, that is, the gate forming portion is retained on the appearance component, which is not particularly limited, and may be set according to actual needs of production.
In order to facilitate explanation of the reason for reduction of the flow lines of the exterior panel, the mold according to the embodiment of the present invention is described below, and explanation is made on the reason for reduction of the flow lines of the exterior surface of the exterior panel in principle in conjunction with the structure of the mold.
The mold for molding the exterior part of the home appliance according to the embodiment of the present invention includes: and a mold core. The mold core is provided with a mold cavity.
The die cavity comprises a connecting plate die cavity and an appearance plate die cavity, wherein the connecting plate die cavity is used for forming the connecting plate, and the appearance plate die cavity is used for forming the appearance plate. The appearance board die cavity extends along the circumference of the connecting plate die cavity, one end of the width direction of the appearance board die cavity is communicated with the periphery of the connecting plate die cavity, the thickness of the other end of the width direction of the appearance board die cavity is minimum, and one side wall surface of the appearance board die cavity in the thickness direction is used for forming the appearance surface of the appearance board. Here, it is understood that one end in the width direction of the appearance plate cavity is an end communicating with the connection plate cavity, and the other end in the width direction of the appearance plate cavity is an end away from the outer periphery of the connection plate cavity.
In some embodiments, the mold core has at least one gate located on a sidewall surface of the connecting plate cavity in a thickness direction, and the at least one gate is disposed adjacent to the appearance plate cavity.
In some embodiments, the mold core has another sidewall surface (i.e., a sidewall surface opposite to the appearance surface for molding the appearance plate) in the thickness direction of the appearance plate cavity and adjacent to the at least one gate of the connecting plate cavity.
The reason for the reduction of flow lines will be described below by taking the gate in the cavity of the connecting plate as an example. The reason for the reduction of flow marks when the gate is in the cavity of the appearance plate will be apparent to those skilled in the art after reading the following description.
Specifically, during injection molding, in the material flowing process, hotter material melt enters the cavity through the pouring gate and contacts with the colder inner wall of the cavity in the flowing process, and the material can be quickly frozen on the inner wall of the cavity to form a thin solidified layer. The arrangement of the metal particles in the solidified layer determines the appearance quality of the spray-free product, and stable flow can form consistent metal particle orientation to obtain better appearance. In this application, at least one runner of mould is located a lateral wall face department of the thickness direction of connecting plate die cavity, and at least one runner of mould is close to the appearance board die cavity, like this when the material flows from the runner of mould, some material can direct flow to appearance board die cavity, thereby can shorten the route that the material flowed to appearance board type cavity from this runner, be favorable to guaranteeing the material by the stable flow of connecting plate die cavity to appearance board type cavity, thereby reduce the flow line of appearance board department, improve the yield of outward appearance part product at least to a certain extent, satisfy user's user demand.
And because the wall thickness of the other end of the width direction of the appearance board die cavity is the minimum, namely along the width direction of the appearance board die cavity, the thickness of the part (called large thickness part) of the appearance board die cavity, which is adjacent to the connecting plate die cavity and is directly communicated with the other end of the width direction of the appearance board die cavity, is inevitably greater than that of the other end of the width direction of the appearance board die cavity (called small thickness part), therefore, when the material flows along the appearance board die cavity in the circumferential direction of the connecting plate die cavity, because the thickness of the large thickness part is greater than that of the small thickness part, the material flows more easily at the large thickness part, the flow speed is faster, the material has a forward convex trend at the large thickness part, obvious forward flow exists at the large thickness part, the actual flow direction of the material at each point of the forward surface is along the outward direction vertical to the tangent line of the forward surface, therefore, the flow direction of each point of the forward surface is divergent, can not intersect to just can not take place to curl and the upset, be favorable to avoiding the material of heavy gauge portion department and the material of light gauge portion department to curl and the upset appearing in the position of leading edge to a certain extent, further guarantee the stability that the material flows, thereby reduce the flow line in the position department that corresponds with heavy gauge portion and light gauge portion of appearance board, improve the yield of outward appearance part product at least to a certain extent, satisfy user's user demand.
There may be several ways to relate the wall thickness variation of the appearance board:
the first method comprises the following steps: the thickness of the exterior panel is gradually reduced in a direction from one end of the exterior panel in the width direction to the other end of the exterior panel in the width direction. Specifically, in the mold, in the direction from one end of the appearance plate type cavity close to the connecting plate cavity in the width direction to the other end of the appearance plate type cavity far away from the connecting plate cavity in the width direction, the thickness of the appearance plate type cavity is gradually reduced, so that when the material flows in the appearance plate type cavity in the circumferential direction of the connecting plate cavity, the material flows more easily at a position with larger thickness and has smaller flow resistance based on the thickness change of the appearance plate type cavity, so that a slope manner is presented on the front edge surface of the material flow as shown in fig. 12, the actual flow direction of the material at each point of the front edge surface is in an outward direction perpendicular to the tangent line of the front edge surface, therefore, the flow directions of each point of the front edge surface are divergent and do not meet, so that curling and overturning do not occur between the materials at the front edge, and the flow of the material is more stable, therefore, the flow lines of the appearance board can be further reduced, the flow lines are further prevented from appearing on the appearance surface of the appearance board, the qualification rate of appearance parts is further improved, the cost is reduced, and the use requirements of users are met.
And the second method comprises the following steps: the thickness of the exterior panel is first kept constant and then gradually decreased in a direction from one end of the exterior panel in the width direction to the other end of the exterior panel in the width direction. Specifically, in the mold, in the direction from one end of the appearance plate type cavity close to the connecting plate cavity in the width direction to the other end of the appearance plate type cavity far away from the connecting plate cavity in the width direction, the thickness of the appearance plate cavity is kept constant and then gradually reduced, so that when the material flows along the appearance plate cavity in the circumferential direction of the connecting plate cavity, the material flows more easily at a position with a larger thickness and has smaller flow resistance based on the thickness change of the appearance plate cavity, so that a surface which is substantially parallel to the width direction of the appearance plate cavity at the position with the same thickness is presented on the front surface where the material flows as shown in fig. 14, a surface which is inclined toward the upstream of the material flow appears at a position with gradually reduced thickness, and the actual flow direction of the material at each point of the front surface is in the outward direction perpendicular to the tangent of the front surface, therefore, each point flow direction on the front edge surface is divergent and can not be intersected, so that the materials at the front edge can not be curled or overturned, and the flow of the materials is more stable, so that the flow lines of the appearance board can be further reduced, the appearance surface of the appearance board is further prevented from being appeared by the flow lines, the qualification rate of appearance parts is further improved, the cost is reduced, and the use requirements of users are met.
Third, the wall thickness of the exterior panel is gradually increased and then gradually decreased in a direction from one end of the exterior panel in the width direction to the other end of the exterior panel in the width direction. Specifically, in the mold, in the direction from one end of the appearance plate type cavity in the width direction to the other end of the appearance plate type cavity in the width direction, the thickness of the appearance plate type cavity is gradually increased and then gradually decreased, so that when the material flows along the length direction of the appearance plate type cavity in the circumferential direction of the connecting plate type cavity, the material flows more easily at a position with a larger thickness and the flow resistance is smaller based on the thickness change of the appearance plate type cavity, so that the front edge surface of the material flow can present a front convex type as shown in fig. 13, the actual flow direction of each point of the front edge surface of the material is the direction perpendicular to the tangent line of the front edge surface, therefore, the flow directions of each point of the front edge surface are divergent and do not meet, the materials at the front edge do not curl and turn over each other, the flow of the material is more stable, and thus, the flow lines of the appearance plate can be further decreased, the flow lines are further prevented from appearing on the appearance surface of the appearance board, the qualification rate of appearance parts is further improved, the cost is reduced, and the use requirements of users are met.
Fourth, the wall thickness of the exterior panel is gradually increased, then maintained, and then gradually decreased in a direction from one end of the exterior panel in the width direction to the other end of the exterior panel in the width direction. Specifically, in the mold, in the direction from one end of the appearance plate type cavity in the width direction to the other end of the appearance plate type cavity in the width direction, the thickness of the appearance plate type cavity is gradually increased, then kept unchanged and then gradually reduced, so that when the material flows along the length direction of the appearance plate type cavity in the circumferential direction of the connecting plate type cavity, the material flows more easily at a position with larger thickness and has smaller flow resistance based on the change of the thickness of the appearance plate type cavity, so that the front edge surface of the material flowing presents a front convex type as shown in fig. 15, the actual flowing direction of the material at each point of the front edge surface is the outward direction perpendicular to the tangent line of the front edge surface, therefore, the flowing directions of each point of the front edge surface are divergent and do not intersect, the materials at the front edge do not curl and turn over mutually, and the flowing of the material is more stable, therefore, the flow lines of the appearance board can be further reduced, the flow lines are further prevented from appearing on the appearance surface of the appearance board, the qualification rate of appearance parts is further improved, the cost is reduced, and the use requirements of users are met.
Therefore, compared to the prior art in which the front surface is concave as shown in fig. 16, the above-mentioned embodiment of the present application is more beneficial to reducing the flow lines of the appearance board.
The greater the wall thickness, the faster the flow rate of the material will be described.
When the material is injected into the mold under a certain condition, the temperature of the material contacting with the cold wall surface of the cavity is sharply reduced, a solidified layer is generated, the flow area of the cavity is reduced along with the increase of the thickness of the solidified layer, and therefore the thickness of the solidified layer has an important influence on the flow resistance. The relation between the fluidity s and the thickness h of the cavity is a formula I:
Figure BDA0002809396300000081
wherein eta isrepIs the viscosity of the material.
From the flowability formula, the flowability s is proportional to the cube of the thickness h, for example, a fifty percent reduction in thickness reduces the flowability by one eighth, which equates to an eight-fold increase in flow resistance. Thus, the greater the thickness of the cavity and thus the lower the flow resistance, the better the flow and the faster the flow rate.

The surface of the panel connection plate 101 is a non-exterior surface, that is, the surface of the panel connection plate 101 is not exposed when the control panel 10 is used in the laundry treating apparatus.
The panel side plate 102 extends along the circumferential direction of the panel connecting plate 101, one end of the panel side plate 102 in the width direction is connected to the outer circumferential wall of the panel connecting plate 101, and the surface of the panel side plate 102 facing away from the panel connecting plate 101 in the thickness direction is an appearance surface. Here, one end of the panel side plate 102 in the width direction is connected to the panel connecting plate 101, and the other end of the panel side plate 102 in the width direction is distant from the panel connecting plate 101.

Therefore, the flow lines of the panel side plate 102 can be reduced at least to a certain extent, the flow lines are prevented from appearing on the appearance surface of the panel side plate 102 at least to a certain extent, the qualification rate of the control panel 10 is improved at least to a certain extent, the cost is reduced, and the use requirements of users are met.
Specifically, after the control panel blank is injection molded by the panel mold 1 and is ejected from the panel mold 1, a part of the material at the panel gate 1111 of the panel mold 1 is left on the control panel blank and forms a panel gate forming portion, and the panel gate forming area 1011 of the control panel 10 is the area where the panel gate forming portion is located. It should be understood that the control panel blank may be reprocessed to cut or partially cut the panel gate forming portion, and certainly, the panel gate forming portion of the control panel blank may not be processed, that is, the panel gate forming portion is retained on the control panel 10, which is not specifically limited to this, and may be set according to actual needs of production.
For the sake of convenience in explaining the reason for the reduction of the flow lines of the panel side panel 102, the following describes the panel mold 1 according to the embodiment of the present invention, and the reason for the reduction of the flow lines of the appearance surface of the panel side panel 102 is explained in principle by combining the structure of the panel mold 1.
As shown in fig. 7, the panel mold 1 for molding the control panel 10 of the laundry treating apparatus according to the embodiment of the present invention includes: a panel core 11. The panel core 11 has a panel cavity.
As shown in fig. 8 to 9, the panel cavities include a panel connecting plate cavity 111 and a panel side plate cavity 112, wherein the panel connecting plate cavity 111 is used for forming the panel connecting plate 101, and the panel side plate cavity 112 is used for forming the panel side plate 102. The panel side plate cavity 112 extends along the circumferential direction of the panel connecting plate cavity 111, one end of the panel side plate cavity 112 in the width direction is communicated with the periphery of the panel connecting plate cavity 111, the thickness of the other end of the panel side plate cavity 112 in the width direction is minimum, and one side wall surface of the panel side plate cavity 112 in the thickness direction, which is far away from the panel connecting plate cavity 111, is used for forming the appearance surface of the panel side plate 102. Here, it is understood that one end in the width direction of the panel-side-plate cavity 112 is an end communicating with the panel-connection-plate cavity 111, and the other end in the width direction of the panel-side-plate cavity 112 is an end away from the outer periphery of the panel-connection-plate cavity 111.
In some embodiments, as shown in fig. 9, the panel core 11 has at least one panel gate 1111 located on a sidewall surface of the panel connecting plate cavity 111 in the thickness direction, and the at least one panel gate 1111 is disposed adjacent to the panel side plate cavity 112.
In some embodiments, the panel mold core 11 has at least one panel gate 1111 located at the other side wall surface in the thickness direction of the panel side plate cavity 112 (i.e., a side wall surface opposite to the external surface for molding the panel side plate 102) and adjacent to the panel connecting plate cavity 111.
The reason for the reduction of the flow pattern will be described below by taking the panel gate 1111 in the panel connecting plate cavity 111 as an example. The reason for the reduction of flow lines when panel gate 111 is in panel side plate cavity 112 will be apparent to those skilled in the art after reading the following description.
Specifically, during injection molding, in the material flowing process, hotter material melt enters the panel cavity through the panel gate 1111 and then contacts with the inner wall of the panel cavity which is cooler in the flowing process, and the material can be rapidly frozen on the inner wall of the panel cavity to form a thin solidified layer. The arrangement of the metal particles in the solidified layer determines the appearance quality of the spray-free product, and stable flow can form consistent metal particle orientation to obtain better appearance. In this application, at least one panel runner 1111 of panel mould 1 is located a lateral wall face of the thickness direction of panel connecting plate die cavity 111, and at least one neighbouring panel curb plate die cavity 112 in panel runner 1111 of panel mould 1, when the material flows out from panel runner 1111 of panel mould 1, partly material can direct flow to panel curb plate die cavity 112, thereby can shorten the route that the material flows to panel curb plate die cavity 112 from this panel runner 1111, be favorable to guaranteeing that the material is by the stable flow of panel connecting plate die cavity 111 to panel curb plate die cavity 112, thereby reduce the flow line of panel curb plate 102 department, improve the yield of control panel 10 product at least to a certain extent, satisfy user's user demand.
And since the wall thickness of the other end of the panel side plate cavity 112 in the width direction is the smallest, that is, along the width direction of the panel side plate cavity 112, the thickness of the portion (called large thickness portion) of the panel side plate cavity 112 adjacent to the panel connecting plate cavity 111 and directly communicated with the other end of the panel side plate cavity 112 in the width direction is inevitably greater than the thickness of the other end of the panel side plate cavity 112 in the width direction (called small thickness portion), so that when the material flows along the panel side plate cavity 112 in the circumferential direction of the panel connecting plate cavity 111, the material flows more easily at the large thickness portion and flows faster because the thickness of the large thickness portion is greater than that of the small thickness portion, the material tends to be convex forward at the large thickness portion, there is a significant forward flow at the large thickness portion, the actual flow direction of the material at each point on the forward surface is an outward direction perpendicular to the forward surface tangent line, therefore, each point flow direction of the front edge surface is divergent and can not intersect, thereby curling and overturning can not occur, the material and the material of the small thickness part at the position of the front edge part can be prevented from curling and overturning to a certain extent, the stability of material flow is further ensured, and therefore flow lines at the position of the panel side plate 102 corresponding to the large thickness part and the small thickness part are reduced, the yield of the control panel 10 product is improved at least to a certain extent, and the use requirement of a user is met.
There may be several ways to relate the wall thickness variation of the panel side panel 102:
the first method comprises the following steps: the wall thickness of the panel side plate 102 gradually decreases in a direction from one end of the panel side plate 102 in the width direction to the other end of the panel side plate 102 in the width direction. Specifically, in the panel mold 1, the thickness of the panel side plate cavity 112 is gradually reduced in the direction from one end in the width direction of the panel side plate cavity 112 to the other end in the width direction of the panel side plate cavity 112, so that when the material flows in the panel side plate cavity 112 in the circumferential direction of the panel connecting plate cavity 111, the material flows more easily at a position having a larger thickness and the flow resistance is smaller based on the thickness change of the panel side plate cavity 112, and in such a manner that the front edge surface of the material flow may exhibit a slope as shown in fig. 12, the actual flow direction of the material at each point of the front edge surface is the direction outward along the tangent line perpendicular to the front edge surface, so that the flow directions of each point of the front edge surface are divergent and do not meet, and thus curling and turning do not occur between the materials at the front edge each other, and the flow of the material is more stable, thus, the flow lines of the panel side plate 102 can be further reduced, the flow lines can be further prevented from appearing on the appearance surface of the panel side plate 102, the yield of the control panel 10 can be further improved, the cost can be reduced, and the use requirements of users can be met.
And the second method comprises the following steps: the wall thickness of the panel side plate 102 is first kept constant and then gradually reduced in a direction from one end of the panel side plate 102 in the width direction to the other end of the panel side plate 102 in the width direction. Specifically, in the panel mold 1, in the direction from one end in the width direction of the panel side plate cavity 112 to the other end in the width direction of the panel side plate cavity 112, the thickness of the panel side plate cavity 112 is kept constant and then gradually decreased, so that when the material flows along the length direction of the panel side plate cavity 112 in the circumferential direction of the panel connecting plate cavity 111, the material flows more easily at a position where the thickness is larger and the flow resistance is smaller, based on the change in the thickness of the panel side plate cavity 112, so that the material will present a surface that is substantially parallel to the width direction of the panel side plate cavity 112 at the position where the thickness is the same as shown in fig. 14, a surface that is inclined toward the upstream of the material flow will appear at a position where the thickness is gradually decreased, and the actual flow direction of the material at each point of the leading surface is in the outward direction perpendicular to the tangent to the leading surface, therefore, the flowing directions of the points on the front edge surface are divergent and can not be intersected, so that the materials at the front edge can not be curled or overturned, and the flowing of the materials is more stable, so that the flow lines of the panel side plate 102 can be further reduced, the appearance surface of the panel side plate 102 is further prevented from being appeared, the qualification rate of the control panel 10 is further improved, the cost is reduced, and the use requirements of users are met.
Third, the wall thickness of the panel side plate 102 is gradually increased and then gradually decreased in a direction from one end of the panel side plate 102 in the width direction to the other end of the panel side plate 102 in the width direction. Specifically, in the panel mold 1, in the direction from one end of the width direction of the panel side plate cavity 112 to the other end of the width direction of the panel side plate cavity 112, the thickness of the panel side plate cavity 112 is gradually increased and then gradually decreased, so that in the circumferential direction of the panel connecting plate cavity 111, when the material flows along the length direction of the panel side plate cavity 112, the material flows more easily at a position with a larger thickness and the flow resistance is smaller based on the thickness change of the panel side plate cavity 112, so that the front convex type shown in fig. 13 is presented on the front edge surface where the material flows, the actual flow direction of the material at each point of the front edge surface is the outward direction perpendicular to the tangent of the front edge surface, and therefore, the flow directions of each point of the front edge surface are divergent and do not meet, and the materials at the front edge do not curl and turn over each other, the material flow is more stable, so that the flow lines of the panel side plate 102 can be further reduced, the flow lines are further prevented from appearing on the appearance surface of the panel side plate 102, the qualification rate of the control panel 10 is further improved, the cost is reduced, and the use requirements of users are met.
Fourth, the wall thickness of the panel side plate 102 is gradually increased, then maintained, and then gradually decreased in a direction from one end of the panel side plate 102 in the width direction to the other end of the panel side plate 102 in the width direction. Specifically, in the panel mold 1, in the direction from one end of the width direction of the panel side plate cavity 112 to the other end of the width direction of the panel side plate cavity 112, the thickness of the panel side plate cavity 112 is gradually increased, then kept constant, and then gradually decreased, so that when the material flows along the length direction of the panel side plate cavity 112 in the circumferential direction of the panel connecting plate cavity 111, the material flows more easily at a position with a larger thickness and has smaller flow resistance based on the change in the thickness of the panel side plate cavity 112, so that the front edge surface of the material flow exhibits a forward convex form as shown in fig. 15, the actual flow direction of the material at each point of the front edge surface is in an outward direction perpendicular to the tangent of the front edge surface, and therefore, the flow directions of each point of the front edge surface are divergent and do not meet, and the material at each front edge does not curl or turn over, the material flow is more stable, so that the flow lines of the panel side plate 102 can be further reduced, the flow lines are further prevented from appearing on the appearance surface of the panel side plate 102, the qualification rate of the control panel 10 is further improved, the cost is reduced, and the use requirements of users are met.
Therefore, the foregoing embodiment of the present application is more advantageous to reduce the flow lines of the panel side plate 102 than the prior art in which the front surface is concave as shown in fig. 16.
The greater the wall thickness, the faster the flow rate of the material will be described.
When the material is injected into the panel mold 1 under a certain condition, the temperature of the cold wall surface of the panel cavity contacted by the material is sharply reduced, a solidified layer is generated, the flow area of the panel cavity is reduced along with the increase of the thickness of the solidified layer, and therefore the thickness of the solidified layer has an important influence on the flow resistance. The relation between the fluidity s and the thickness h of the panel cavity is a formula I:
Figure BDA0002809396300000151
wherein eta isrepIs the viscosity of the material.
From the flowability formula, the flowability s is proportional to the cube of the thickness h, for example, a fifty percent reduction in thickness reduces the flowability by one eighth, which equates to an eight-fold increase in flow resistance. Thus, the greater the thickness of the panel cavity and thus the lower the flow resistance, the better the flow and the faster the flow rate.
In summary, the panel mold 1 for molding the control panel 10 of the laundry treating apparatus according to the embodiment of the present invention is configured to minimize the thickness of the other end of the panel side plate cavity 112 in the width direction. Therefore, the flow lines of the panel side plate 102 can be reduced at least to a certain extent, the flow lines are prevented from appearing on the appearance surface of the panel side plate 102 at least to a certain extent, the qualification rate of the control panel 10 is improved at least to a certain extent, the cost is reduced, and the use requirements of users are met.
