Detailed Description

Embodiments of the present application are described in further detail below with reference to the accompanying drawings and examples. The following examples are illustrative of the present application but are not intended to limit the scope of the present application.

In this application, mm is the international unit millimeter. The present application will now be described in further detail with reference to the accompanying drawings and specific examples.

In order to improve the visual appearance of the product, the appearance of a part of plastic parts of the product is required to have a gorgeous metal appearance effect, and in order to enable the plastic parts to have a gorgeous metal appearance effect, in the related art, the manufacturing process of the plastic parts is mainly injection molding and spraying processes, namely, metal powder is sprayed on the outer surface of an injection molding blank formed by injection molding, and the sprayed plastic parts have a gorgeous metal appearance effect, but the spraying processes have the defects of large pollution, high cost, low qualification rate, unrecyclability after scrapping and the like.

In order to solve the defects of the spraying process, the spraying-free thermoplastic engineering plastic is generated, and the spraying-free injection molding is adopted to give the metal appearance effect to the product, so that the spraying process is canceled, and the emission of pollutants in the spraying process is avoided. However, flow marks are easily generated in both the spray injection molding process and the spray-free injection molding process. Because the melt of the spraying-free thermoplastic engineering plastic contains metal powder, the melt is easy to cause uneven distribution of the metal powder in the flowing process of the melt in the cavity of the die in the injection molding process, the produced spraying-free door ring product has uneven light scattering under the irradiation of light, some parts have dark colors, flow marks are formed visually, the product has flow mark defects, the appearance quality of the spraying-free door ring can not meet the appearance requirement of the product, the yield is low, the material is wasted, and the production cost is high. Therefore, it is difficult to use a spray-free injection molding process for existing plastic parts having high quality appearance requirements.

Referring to fig. 2 to 5, an embodiment of a door ring 100 is provided, and the door ring 100 is an integral injection molding, for example, a spraying-free integral injection molding. For example, the door ring 100 of the present embodiment is formed by injection molding a melt of a metal powder-containing matrix. That is, the material of the door ring 100 includes a base and metal powder distributed in the base. The door ring 100 formed by the matrix containing the metal powder has a metallic appearance, and no additional metal coating is required, i.e. the plastic part is a spraying-free plastic part.

For convenience of description, a melt of a metal powder-containing matrix is described below as forming the door ring 100 by injection molding.

The type of metal powder is not limited, and exemplary metal powders include, but are not limited to, copper, silver, and/or aluminum, among others.

The metal powder refers to a form of a metal in a granular form. The size of the particles is not limited in this application.

The type of matrix is not limited, and exemplary matrices include, but are not limited to, resins and the like.

The door ring 100 includes a reinforcing rib and an annular plate body 100'. The panel body 100' serves as a body structure of the door ring 100.

Referring to fig. 2 and 3, the plate body 100' includes a connection plate 2 and an inner ring plate 3, wherein the connection plate 2 surrounds the inner ring plate 3 in the circumferential direction. The profile of the connection plate 2 is substantially circular.

Referring to fig. 8, the surface of the first side of the inner ring plate 3 in the thickness direction is an exterior surface 31.

The surface of the connection plate 2 is a non-exterior surface, that is, any surface of the connection plate 2 is a non-exterior surface.

The non-exterior surface is not exposed outside the clothes treating apparatus, and the exterior surface is exposed outside the clothes treating apparatus, and the non-exterior surface is not visible to the user but is visible to the user during normal use of the clothes treating apparatus.

Referring to fig. 2 to 5, the connecting plate 2 is provided with a gate forming portion 21, and the gate forming portion 21 is adapted to correspond to a gate of a mold.

The reinforcing ribs are provided on the surface of the second side of the inner ring plate 3 in the thickness direction, and the reinforcing ribs are not parallel to the circumferential track defined by the connecting plate 2. Specifically, the circumferential track refers to a series of concentric circles centered on the center of the connection plate 2, and the shape of the reinforcing rib does not coincide with any one of the concentric circles.

Illustratively, the inner ring plate 3 has a size, in the radial direction of the plate body 100', which is much larger than the size of the connection plate 2, for example, 3 to 6 times the connection plate 2.

The plate body 100' is integrally a thin-walled injection molded part, and the reinforcing ribs can play a role in reinforcing the structural strength of the inner ring plate 3.

In order to clearly illustrate the door ring 100 provided in the embodiments of the present application, a mold provided in the embodiments of the present application is described first, and the mold is used for injection molding the door ring 100 in the embodiments of the present application.

The embodiment of the application provides a mold, which is provided with a cavity and a gate. During injection molding, melt enters the cavity from the gate, fills the cavity, and after being molded and cooled, opens the mold to obtain the door ring 100.

The cavity comprises an inner ring plate cavity for forming the inner ring plate 3, a connecting plate cavity for forming the connecting plate 2 and a rib cavity for forming the reinforcing ribs, the connecting plate cavity surrounds the periphery of the inner ring plate cavity, and the pouring gate is arranged on one side of the connecting plate cavity along the thickness direction.

The wall surface of one side of the inner ring plate cavity along the thickness direction is used for forming the appearance surface of the connecting plate 2, the rib cavity is arranged on the second side of the inner ring plate cavity along the thickness direction, and the length direction of the rib cavity is not parallel to the circumferential track defined by the connecting plate cavity.

The specific analysis for the cause of flow mark generation is described as follows:

referring to fig. 1, during the melt flow process, the hotter melt contacts the cooler mold during the flow process, and the hotter melt rapidly freezes on the cavity walls of the cavity to form a thinner solidified layer. The orientation of the metal powder in the solidified layer determines the appearance of the injection molding piece, and the stably flowing metal powder can form consistent metal powder orientation to obtain better appearance. When the melt in the appearance cavity 1000 flows through the rib-level cavity 2000, the flow direction of the melt in the appearance cavity 1000 is divided into two, one part of the melt continues to flow along the original flow direction, the other part of the melt flows to the rib-level cavity 2000, if the rib-level cavity 2000 is parallel to the whole flow direction of the melt in the appearance cavity 1000, the melt in the appearance cavity 1000 continuously enters the rib-level cavity 2000, and the melt in the rib-level cavity 2000 easily flows back to the appearance cavity 1000, so that frequent impact on the appearance surface is caused by the melt flowing back from the rib-level cavity 2000 to the appearance cavity 1000, an unstable flow field is easily formed in the area where the appearance cavity 1000 is located in the rib-level structure under the continuous flow of the melt, and the solidification layer of the appearance surface of the appearance cavity 1000 is destroyed under the continuous action of the fluid pressure, so that the solidification layer metal powder of the appearance surface is disturbed and appears as flow marks. That is, the rib structure parallel to the melt flow direction easily causes flow marks on the appearance surface.

The exterior cavity 1000 is a cavity for forming a structure having an exterior surface, and is, for example, the above-described inner ring plate cavity, and the exterior plate cavity described below. Rib cavity 2000 refers to a cavity for molding a rib structure, such as a rib cavity of the present application.

The principle of reducing flow marks in the embodiment of the application is specifically described as follows:

in this embodiment, when the fuse-element flows in the connecting plate die cavity, roughly along the circumference flow of connecting plate die cavity, when the flow direction of fuse-element in rib die cavity and the interior annular plate die cavity is nonparallel, that is to say, when the extending direction of strengthening rib is nonparallel with the melt flow direction, the fuse-element in the interior annular plate die cavity can flow through the rib die cavity fast, get into the fuse-element in the rib die cavity and be difficult for flowing from the rib die cavity, avoid the fuse-element backward flow in the rib die cavity to the interior annular plate die cavity to a certain extent to reduce the flow mark on the outward appearance face of the interior annular plate 3 of shaping.

According to the door ring 100 disclosed by the embodiment of the application, the reinforcing ribs are used for increasing the structural strength of the inner annular plate 3, and because the circumferential tracks defined by the reinforcing ribs and the connecting plate 2 are not parallel, the appearance surface of the inner annular plate 3 can be prevented from being frequently impacted due to the backflow of a melt forming the reinforcing ribs to a certain extent during injection molding, the stability of a flow field at the intersection of the appearance surface and the reinforcing ribs is ensured, and therefore the flow mark of the appearance surface is improved.

Illustratively, the angle between the rib and the circumferential track defined by the web 2 is greater than 30 °, which angle range enables more effective suppression of melt backflow in the rib cavity during injection molding, further improving flow mark phenomena. For example, in some embodiments, the ribs extend in a direction approximately perpendicular to the circumferential track defined by the web 2.

As an example, referring to fig. 4, 5 and 6, the number of the reinforcing ribs is plural, wherein a part of the reinforcing ribs are longitudinal reinforcing ribs 51 and another part of the reinforcing ribs are diagonal reinforcing ribs 52, that is, the types of the reinforcing ribs are at least divided into two types, one of which is longitudinal reinforcing ribs 51 and the other is diagonal reinforcing ribs 52. The number of the vertical reinforcement ribs 51 is plural. Each longitudinal reinforcement rib 51 is radially distributed, and both ends of the diagonal brace rib 52 are connected to the longitudinal reinforcement rib 51.

In this embodiment, the diagonal brace bars 52 function to strengthen the structural strength of the vertical reinforcement bars 51 to better strengthen the structural strength of the inner ring plate 3.

Illustratively, the longitudinal reinforcement ribs 51 form an angle of no more than 10 ° with the radial direction defined by the web 2. That is, the longitudinal ribs 51 extend in the radial direction or the approximate radial direction, and thus, the longitudinal ribs 51 are perpendicular or approximately perpendicular to the circumferential direction of the circular locus defined by the connection plate 2.

For example, referring to fig. 6, the included angle β between the longitudinal reinforcement ribs 51 and the diagonal brace ribs 52 is 30 ° to 60 °, for example, 30 °, 35 °, 40 °, 43 °, 50 °, 56 °, 60 °, and the like. The included angle range can play a role in better structural strength and improve the phenomenon of flow marks.

Illustratively, the thickness of the inner ring plate 3 is greater than the thickness of the connecting plate 2.

For the mold, the thickness of the inner ring plate cavity is greater than the thickness of the web cavity.

When the melt is injected into the mold, the melt contacts the cooler cavity wall surface of the cavity, the temperature is reduced, a solidified layer is generated on the cavity wall surface, the flow area of the cavity is reduced along with the thickness of the solidified layer, and the fluidity is proportional to the cube of the thickness, so that the larger the thickness of the cavity is, the smaller the flow resistance is, the better the fluidity is, and the faster the flow velocity is.

During pouring, fluid flows from the periphery of the pouring gate to the connecting plate cavity and the inner annular plate cavity, and because the flow speed of the melt in the inner annular plate cavity is greater than that in the connecting plate cavity, the inner annular plate cavity can be filled with the melt quickly, the inner annular plate cavity is filled with the melt earlier than the connecting plate cavity, the melt is more prone to flow from the inner annular plate cavity to the connecting plate cavity at the junction of the inner annular plate cavity and the connecting plate cavity, the probability that the melt in the connecting plate cavity flows to the inner annular plate cavity is smaller, so that the phenomenon that the melt in the connecting plate cavity continuously impacts a solidification layer in the inner annular plate cavity is reduced, the probability that flow marks appear on the appearance surface of the inner annular plate 3 is reduced or avoided, and the yield of the gate ring 100 is improved.

Illustratively, the thickness of the inner ring plate 3 is 2mm to 3mm, e.g., 2mm, 2.3mm, 2.5mm, 2.7mm, 2.9mm, 3mm, etc.

The thickness of the inner ring plate cavity is 2mm to 3mm, for example, 2mm, 2.3mm, 2.5mm, 2.7mm, 2.9mm, 3mm, etc. for the mold.

For example, referring to fig. 3 and 8, the plate body 100 'includes an exterior plate 1, the exterior plate 1 is circumferentially surrounded by a connection plate 2, that is, the exterior plate 1, the connection plate 2, and an inner ring plate 3 are sequentially disposed along a direction from a radially outer end to a radially inner end of the plate body 100'.

Referring to fig. 8, the surface of one side of the appearance board 1 in the thickness direction is an appearance surface 11, and the thickness of one end of the appearance board 1 near the connecting board 2 is greater than the thickness of the connecting board 2.

For the mold, the cavity comprises an appearance plate cavity for forming the appearance plate 1, the appearance plate cavity surrounds the circumference of the connecting plate cavity, the wall surface of one side of the appearance plate cavity along the thickness direction is used for forming the appearance surface of the appearance plate 1, and the thickness of one end, close to the connecting plate cavity, of the appearance plate cavity is larger than that of the connecting plate cavity.

During pouring, fluid flows from the periphery of the pouring gate to the connecting plate cavity, the inner annular plate cavity and the appearance plate cavity, the flow speed of melt in the appearance plate cavity is higher than that in the connecting plate cavity, so that the appearance plate cavity can be quickly filled with the melt, the appearance plate cavity is filled with the melt earlier than the connecting plate cavity, and at the junction of the appearance plate cavity and the connecting plate cavity, the thickness of the connecting plate cavity is smaller, so that a certain flow blocking effect is achieved, the probability that the melt in the connecting plate cavity flows to the appearance plate cavity is reduced, the probability that the melt in the connecting plate cavity impacts the appearance surface of the appearance plate cavity is reduced, a stable flow field is easier to form in the formation of the appearance plate 1, the probability of flow marks is reduced, and the yield of the door ring 100 is improved.

It should be noted that, because the flow velocity of the melt in the appearance plate cavity is greater than the flow velocity in the connecting plate cavity, therefore, at the juncture of the connecting plate cavity in the appearance plate cavity, the melt in the appearance plate cavity is easy to curl and turn over towards one side of the connecting plate cavity, however, because the part molded by the connecting plate cavity is the connecting plate 2, the surface of the connecting plate 2 is a non-appearance surface, even if flaws such as marks appear, the appearance of the door ring 100 is not affected, therefore, the connecting plate 2 does not require the flaws, and some possible flaws and some unavoidable flaws can be put on the connecting plate 2.

Illustratively, the appearance surface of the appearance plate 1 is a main appearance surface, the appearance surface of the inner ring plate 3 is a secondary appearance surface, and the thickness of one end of the inner ring plate 3 close to the connecting plate 2 is smaller than the thickness of one end of the appearance plate 1 close to the connecting plate 2.

The main appearance surface is an important appearance surface of the product, and a user can feel and see the product. The inner ring plate 3 is the secondary appearance plate 1, the secondary appearance surface of the inner ring plate 3 is also an appearance surface which can be seen by a user, but the importance degree is lower than that of the main appearance surface, for example, a light-transmitting plate is arranged on the outer side of the secondary appearance surface of the inner ring plate 3, the user can see the secondary appearance surface of the inner ring plate 3, but the user cannot touch the light-transmitting plate, the light-transmitting plate can play a certain light blocking effect to a certain extent, and the sensitivity of the user to flaws on the main appearance surface is higher than that of flaws on the secondary appearance surface of the inner ring plate 3.

For example, referring to fig. 2, 3, 7, 8 and 9, the connecting plate 2 is provided with a material blocking portion 22, the material blocking portion 22 is surrounded on opposite sides and radially inner sides of the gate forming portion 21 along the circumferential direction of the connecting plate 2, and the thickness of the material blocking portion 22 is smaller than the thickness of the connecting plate 2.

That is, the blocking portion 22 is not provided on the side of the gate forming portion 21 close to the exterior panel 1, the thinning process is not performed on the side of the gate forming portion 21 connected to the exterior panel 1, and the thinning process is performed on the remaining peripheral portion of the gate forming portion 21.

The material blocking portion 22 is thinned, and in view of the outside of the door ring 100, the material blocking portion 22 may have a groove structure formed on one side of the door ring 100 in the thickness direction, or may have a groove structure formed on both sides of the door ring 100 in the thickness direction.

For the mold, the cavity includes a material blocking cavity for forming the material blocking portion 22, the material blocking cavity is surrounded on opposite sides and a radial inner side of the gate along the circumferential direction of the connecting plate 2, and the thickness of the material blocking cavity is smaller than that of the connecting plate cavity.

According to the embodiment of the application, during pouring, a melt enters a gate cavity from the gate, one part of the melt directly flows to an appearance plate cavity from the gate cavity, the other part of the melt directly flows to a blocking cavity from the gate cavity, and then flows to a connecting plate cavity and an inner ring plate cavity from the blocking cavity. The thickness of the material blocking cavity is smaller than that of the gate cavity and smaller than that of the connecting part of the appearance plate cavity and the gate cavity, so that the resistance of the melt flowing from the gate to the appearance plate cavity is smaller than that flowing through the material blocking cavity, and the speed and the flow rate of the melt flowing to the appearance plate cavity are higher than those of the melt flowing to the connecting plate cavity and the inner ring plate cavity through the material blocking cavity, namely, due to the thinning design of the material blocking cavity, a certain flow blocking effect is achieved on the melt, and the speed and the flow rate of the melt flowing to the connecting plate cavity and the inner ring plate cavity are reduced.

It should be noted that, since the material blocking cavity does not completely block the flow path between the gate and the connecting plate cavity, nor does it completely block the flow path between the gate and the inner annular plate cavity, the melt flows to the connecting plate cavity and the inner annular plate cavity through the material blocking cavity at the same time when the melt flows to the appearance plate cavity, but the flow rate and the flow rate are smaller than those in the appearance plate cavity.

The design of material blocking die cavity makes the appearance board die cavity be full of the fuse-element fast, the fuse-element is full of the time difference that has a small margin between appearance board die cavity and the connecting plate die cavity that is full of, in the juncture of appearance board die cavity and connecting plate die cavity, the fuse-element more tends to flow from appearance board type chamber to connecting plate die cavity, the probability that the fuse-element flow in the connecting plate die cavity flows to appearance board die cavity is less, so, the fuse-element in the reducing connecting plate die cavity continuously strikes the probability of solidifying layer in the appearance board die cavity, the probability of appearing the flow mark of appearance board 1 of appearance board shaping that reduces or avoids, promote the yield of door circle 100.

The material blocking portion 22 extends substantially along the periphery of the gate forming portion 21, and it is understood that the material blocking portion 22 may be entirely continuous along the extending direction or may be discontinuous in a locally narrow range.

For example, referring to fig. 2 and 9, the material blocking portion 22 is continuously provided around the periphery of the gate forming portion 21 other than the connection portion with the exterior panel 1 to provide a better material blocking effect.

For example, referring to fig. 9, the width H of the dam portion 22 in the direction away from the gate forming portion 21 is 5mm to 15mm. For example, 5mm, 5.5mm, 6mm, 6.3mm, 7mm, 7.6mm, 8mm, 9mm, 10mm, 10.4mm, 11mm, 12mm, 12.7mm, 13mm, 14mm, 15mm, etc. That is, the length of the flow path of the melt in the dam 22 is not less than the above-described width of the dam 22.

For the mold, the width of the resist cavity from the direction close to the gate cavity to the direction away from the gate cavity is 5mm to 15mm, for example, 5mm, 5.5mm, 6mm, 6.3mm, 7mm, 7.6mm, 8mm, 9mm, 10mm, 10.4mm, 11mm, 12mm, 12.7mm, 13mm, 14mm, 15mm, and the like.

The width range ensures that the material blocking cavity can play a good flow blocking effect in the casting process, and the thinning treatment of the material blocking part 22 does not obviously influence the structural strength.

It should be noted that, if the width of the material blocking portion 22 is too large, the size of the material blocking portion 22 due to the thinning process may affect the overall structural strength of the door ring 100, and if the size of the material blocking portion 22 is too narrow, the flow blocking effect is not ideal, so the width of the material blocking portion 22 is controlled in the above range in the embodiment of the present application, and the effect of the overall structural strength of the flow blocking and the door ring 100 can be satisfied.

Illustratively, the thickness of the material blocking portion 22 is 0.3mm to 1.8mm, for example, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, and the like.

For the mold, the thickness of the resist cavity is 0.3mm to 1.8mm, for example, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, and the like.

In this embodiment, the thickness ranges of the material blocking portion 22 and the material blocking cavity can better control the proper flow rate and flow rate of the melt flowing through the material blocking cavity.

Illustratively, the thickness of the exterior panel 1 is 2.5mm to 3.5mm, for example, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, and the like.

The thickness of the appearance plate cavity is 2.5mm to 3.5mm, for example, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, etc. for the mold.

In the embodiment, the thickness ranges of the appearance plate 1 and the appearance cavity can ensure that the melt has better flowing speed in the appearance cavity, and the appearance plate 1 can also have structural strength and material cost.

The design plate 1 may be of an equal thickness design or an unequal thickness design, and is not limited thereto.

Illustratively, the thickness of the web 2 is 1.5mm to 2.5mm, e.g., 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, etc.

For the die, the thickness of the connecting plate cavity is 1.5 mm-2.5 mm. For example, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, etc.

Under the condition that the thickness of the connecting plate 2 is smaller than that of the appearance plate 1, the connecting plate 2 has a proper thickness range, and the structural strength and the material cost of the connecting plate 2 are guaranteed.

Illustratively, the thickness of the gate forming portion 21 is 1.5mm to 4mm, for example, 1.5mm, 1.8mm, 2.0mm, 2.3mm, 2.7mm, 3mm, 3.4mm, 3.6mm, 3.8mm, 4mm, and the like.

The thickness of the gate cavity is 1.5 to 4mm for the mold, for example, 1.5mm, 1.8mm, 2.0mm, 2.3mm, 2.7mm, 3mm, 3.4mm, 3.6mm, 3.8mm, 4mm, and the like.

In this embodiment, the thickness ranges of the gate forming portion 21 and the gate cavity facilitate the flow of the melt around the gate cavity with a large flow rate in the gate cavity, and the injection efficiency is improved.

In the above-described thickness range, the value is required to be obtained on the premise that the relative thickness relationship is satisfied.

For example, the thickness of the material blocking portion 22 is smaller than the thickness of the gate forming portion 21, and when the thickness of the material blocking portion 22 is 1.8mm, the thickness of the gate forming portion 21 needs to be taken within a range of more than 1.8mm and not more than 4 mm. When the thickness of the material blocking portion 22 is 0.3mm, the thickness of the gate forming portion 21 may be arbitrarily set within a range of 1.5mm to 4 mm.

Illustratively, the thickness of the portion of the dam 22 located radially inward of the gate forming portion 21 is greater than the thickness of the portion of the dam 22 located on either side of the gate forming portion 21 in the circumferential direction.

In this embodiment, the flow rate and the speed of the melt flowing from the material blocking cavity to the inner annular plate cavity are not smaller than the flow rate and the speed flowing to the connecting plate cavity, and in addition, the thickness of the inner annular plate cavity is larger than the thickness of the connecting plate cavity, so that the flow rate of the melt is larger than the flow rate in the connecting plate cavity, the melt is filled with the inner annular plate cavity and the connecting plate cavity, a small time difference exists between the inner annular plate cavity and the connecting plate cavity, and at the junction of the appearance plate cavity and the connecting plate cavity, the melt is more prone to flow from the appearance plate cavity to the connecting plate cavity, the probability that the melt in the connecting plate cavity continuously impacts a solidified layer in the appearance plate cavity is smaller, the probability that flow marks appear on the appearance surface of the appearance plate 1 formed by the appearance plate cavity is reduced or avoided, and the yield of the door ring 100 is improved.

For example, the thickness of the portion of the dam cavity connected between the inner annular plate cavity and the gate cavity is 0.1mm to 0.2mm greater than the thickness of the portion of the dam cavity connected between the gate cavity and the web cavity.

The number of gate forming portions 21 may be one or a plurality. Accordingly, the number of gates of the mold may be one or more.

Illustratively, the number of gate forming portions 21 is plural, and the plural gate forming portions 21 are arranged at intervals in the circumferential direction of the connecting plate 2.

Illustratively, the plurality of gates are sequentially opened in the circumferential direction at preset time intervals. That is, the plurality of gates do not open the injection at the same time, but there is a sequence. On the one hand, a plurality of pouring gates are adopted, so that the problem that a single pouring gate is difficult to fill a cavity rapidly is avoided. On the other hand, the multiple gates are sequentially opened according to the preset time interval, so that one-way flow of the melt can be ensured, a continuous leading flow front is formed, and the probability of an unstable flow field is reduced.

It should be noted that, the specific duration of the preset time interval may be set according to the actual production requirement, which is not limited in this application.

For example, referring to fig. 2, the plate body 100' includes a longitudinal ring plate 4, the longitudinal ring plate 4 extending from a radially inner end of the inner ring plate 3 toward a side of the inner ring plate 3 in a thickness direction and facing away from the outer surface, wherein a thickness of the longitudinal ring plate 4 is smaller than a thickness of the inner ring plate 3.

For the mold, the cavity of the mold comprises a longitudinal ring plate cavity, the longitudinal ring plate cavity is used for forming the longitudinal ring plate 4, and the thickness of the longitudinal ring plate cavity is larger than that of the longitudinal ring plate cavity.

In the injection molding process, the melt flows from the inner annular plate cavity to the longitudinal annular plate cavity, so that a stable flow field is formed, the flow mark phenomenon of the appearance surface of the inner annular plate 3 is improved, and the yield of the door ring 100 is improved.

The end surface of the radially inner end of the vertical ring plate 4 is also a minor outer surface.

Illustratively, the longitudinal ring plate 4 has a thickness of 1.5mm to 2.5mm, for example, 1.5mm, 1.7mm, 1.9mm, 2.mm, 2.3mm, 2.4mm, 2.5mm, etc.

The thickness of the longitudinal ring plate cavity is 1.5mm to 2.5mm, for example, 1.5mm, 1.7mm, 1.9mm, 2.mm, 2.3mm, 2.4mm, 2.5mm, etc. for the mold.

Illustratively, longitudinal stiffening ribs 51 extend from the radially outer surface of the longitudinal ring plate 4 to the connecting plate 2. In this way, the vertical reinforcement ribs 51 can reinforce the structural strength of the junction of the vertical ring plate 4 and the inner ring plate 3.

The inner ring plate 3 may be of an equal thickness or a non-equal thickness along the radial direction of the inner ring plate 3. For example, the thickness of the inner ring plate 3 decreases in turn or increases in turn in a radially inward direction.

Along the radial direction of the connecting plate 2, the connecting plate 2 can be of an equal thickness design or a non-equal thickness design. For example, in a radially inward direction, the thickness of the connection plate 2 decreases in turn or increases in turn.

The appearance plate 1 may be designed to have a uniform thickness or a non-uniform thickness along the substantially radial direction of the appearance plate 1. For example, the thickness of the exterior panel 1 decreases in order or increases in order in the radially inward direction.

For example, referring to fig. 5, the connection plate 2 has a mounting region 23 for mounting the hinge, for example, a mounting hole 23a is provided in the mounting region 23, and a fastener passes through the mounting hole 23a and connects the hinge and the door ring 100.

Specifically, the door body in which the door gasket 100 is located is connected to the cabinet of the laundry treating apparatus by a hinge, and the installation area 23 needs to withstand a relatively large force, which requires a high structural strength. Thus, in the embodiment of the present application, diagonal braces 52 are provided on one side of the inner ring plate 3 in the arc range of the mounting area 23 to further strengthen the structural strength of the area.
