Generally, a door 1 for a laundry treatment apparatus, such as a drum washing machine, is used to implement a component for putting and taking laundry in and out of the washing machine, and has dual requirements of function and appearance.

Most of the manufacturing processes of the door ring 1 are injection molding and spraying processes, the sprayed door ring 1 has gorgeous metal appearance effects, but the spraying processes have the defects of high pollution, high cost, low qualification rate, incapability of recycling after scrapping and the like, seriously affect the health of the environment and 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.

No matter the door ring 1 is manufactured by adopting the spraying-free material or the door ring 1 is manufactured by adopting the injection molding and spraying processes, for the material with poor fluidity, especially the spraying-free material containing metal particles, because the spraying-free material contains the metal particles and other substances, the metal particles are unevenly distributed when the material encounters obstacles 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 111 of the product, the qualified rate of the product is low, and the use requirement of a user cannot be met. In the following description, a coating-free material containing metal particles is taken as an example, that is, the door ring 1 may be a coating-free member including a resin matrix and metal particles distributed in the resin matrix. Optionally, the metal particles are copper, aluminum or silver.

A door ring 1, a laundry treating apparatus, and a mold 2 of the laundry treating apparatus according to an embodiment of the present invention are described below with reference to the accompanying drawings. Optionally, the laundry treating apparatus is a washing machine, a dryer or a washer-dryer.

Particularly, door circle 1 is the integrative injection moulding spare, and mould 2 can be used for shaping door circle 1, and from this, 1 structure of door circle, the stability of performance can not only be guaranteed to the structure of an organic whole to convenient shaping, manufacturing are simple, have saved unnecessary assembly part and connection process moreover, guarantee the reliability that door circle 1 connects, and in addition, the bulk strength and the stability of the structure of an organic whole formation are higher, and it is more convenient to assemble, and the life-span is longer.

As shown in fig. 1, 2, 4 and 6A, the door ring 1 of the clothes treating apparatus according to the embodiment of the present invention includes an appearance plate 11 and a fixing plate 12, the appearance plate 11 is formed in a ring shape, the fixing plate 12 is formed in a ring shape, and the fixing plate 12 includes a ring-shaped main body portion 121 and a ring-shaped connecting portion 122. As shown in fig. 3 and 5, the width direction of the appearance plate 11 (the a1 direction shown in fig. 3) may extend along the axial direction of the appearance plate 11, and of course, the width direction of the appearance plate 11 may have an angle with the axial direction of the appearance plate 11. The inner peripheral wall of the connecting portion 122 is connected to the outer peripheral wall of the main body portion 121, the outer peripheral wall of the connecting portion 122 is connected to the inner peripheral wall of the exterior plate 11, and at least one gate forming region adapted to correspond to the gate 2127 of the mold 2 is provided on the connecting portion 122.

Specifically, after the door ring 1 is injection molded by using the mold 2 and the door ring 1 is removed from the mold 2, a part of the material at the gate 2127 of the mold 2 is left on the door ring 1 and forms a gate forming portion 1224 of the door ring 1, and the gate forming region is the region where the gate forming portion 1224 of the door ring 1 is located. It should be understood that the gate forming portion 1224 of the gate ring 1 may be cut or partially cut by reprocessing the gate ring 1, and of course, the gate forming portion 1224 of the gate ring 1 may not be processed, that is, the gate forming portion 1224 of the gate ring 1 is remained on the gate ring 1, as shown in fig. 3, which is not particularly limited to this, and may be set according to actual needs of production.

The outer circumferential wall of the appearance plate 11 is formed as an appearance face 111, and the remaining surface of the appearance plate 11 and all surfaces of the fixing plate 12 may be non-appearance faces, which are exposed when used in the laundry treating apparatus. The non-exterior surface means that the surface is not exposed when used in the laundry treating apparatus.

As shown in fig. 3 and 5, the thickness of the exterior panel 11 (the thickness in the a2 direction shown in fig. 3) is larger than the thickness of the connecting portion 122 (the thickness in the direction perpendicular to the extending direction of the connecting portion 122). Therefore, the flow lines of the appearance board 11 can be reduced at least to a certain extent, the flow lines are prevented from appearing on the appearance surface 111 of the appearance board 11 at least to a certain extent, the qualification rate of the appearance board 11 is improved at least to a certain extent, the cost is reduced, and the use requirements of users are met.

In order to facilitate the explanation of the reason for reducing the flow lines on the appearance surface 111 of the appearance board 11, the mold 2 according to the embodiment of the present invention is described below, and the mold 2 may be used to mold the door jamb 1, and the reason for reducing the flow lines on the appearance surface 111 of the appearance board 11 is described in principle in combination with the structure of the mold 2.

As shown in fig. 7-13, the mold 2 according to the embodiment of the present invention includes a mold core 21, and the mold core 21 has a cavity.

Specifically, as shown in fig. 8, 10 and 12, the cavities include an appearance plate cavity 211 and a fixing plate cavity 212, the appearance plate cavity 211 being used to mold the appearance plate 11, and the fixing plate cavity 212 being used to mold the fixing plate 12. Fixing plate pocket 212 further includes a connecting portion pocket 2121 and a body portion pocket 2126, connecting portion pocket 2121 being for molding connecting portion 122, and body portion pocket 2126 being for molding body portion 121.

The main body part cavity 2126, the connecting part cavity 2121 and the appearance plate cavity 211 are all formed in a ring shape, the connecting part cavity 2121 is communicated with the periphery of the main body part cavity 2126, the appearance plate cavity 211 is communicated with the periphery of the connecting part cavity 2121, the mold core 21 is provided with a sprue 2127 positioned at one axial end of the connecting part cavity 2121, the thickness of the appearance plate cavity 211 (the thickness in the direction B1 shown in fig. 9) is greater than the thickness of the connecting part cavity 2121 (the thickness in the direction perpendicular to the extending direction of the connecting part cavity 2121), and one side surface of the appearance plate cavity 211, which is far away from the connecting part cavity 2121, is used for molding the appearance surface 111 of the appearance plate 11.

Specifically, during injection molding, in the process of material flowing, a hotter material melt enters the connecting portion cavity 2121 through the gate 2127 and then contacts with the inner wall of the cooler connecting portion cavity 2121 during flowing, and the material is rapidly frozen on the inner wall of the connecting portion cavity 2121 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, since the gate 2127 is located at the connecting part cavity 2121, when the material flows out from the gate 2127 of the mold 2, the material can flow to both sides of the main body cavity 2126 and the exterior plate type cavity 211 and gradually fill the connecting part cavity 2121, the exterior plate type cavity 211 and the main body cavity 2126. Because the thickness of outward appearance board die cavity 211 is greater than the thickness of connecting portion die cavity 2121, when the material flows, the material flows more easily in big thickness portion department, the velocity of flow is faster, the material is towards outward appearance board die cavity 211 flow resistance little, the material can be very fast flow outward appearance board die cavity 211 and be full of outward appearance board die cavity 211 and the shaping of outward appearance board die cavity 211, it is full of the back again to continue to flow to outward appearance die cavity to avoid other positions, reduce the condition that the outward appearance face 111 at outward appearance board 11 forms the flow line, improve the yield of product at least to a certain extent, satisfy user's user demand.

It is to be understood that the thickness of the appearance board 11 being greater than the thickness of the connection portion 122 means that the thickness of any position of the appearance board 11 is greater than the thickness of any position of the connection portion 122, that is, the minimum thickness of the appearance board 11 is greater than the maximum thickness of the connection portion 122, and correspondingly, the thickness of the appearance board cavity 211 being greater than the thickness of the connection portion cavity 2121 means that the thickness of any position of the appearance board cavity 211 is greater than the thickness of any position of the connection portion cavity 2121, that is, the minimum thickness of the appearance board cavity 211 is greater than the maximum thickness of the connection portion cavity 2121.

The greater the wall thickness, the faster the flow rate of the material will be described.

When the material is injected into the mold 2 under a certain condition, the temperature of the cold wall surface of the material contacting the connecting part cavity 2121 is sharply reduced, and a solidified layer is generated, and the flow area of the connecting part cavity 2121 is reduced along with the increase of the thickness of the solidified layer, so that the thickness of the solidified layer has an important influence on the flow resistance. The relationship between the fluidity s and the thickness h of the connecting part cavity 2121 is formula one:

wherein eta rep is 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.

In short, according to the utility model discloses mould 2, because runner 2127 and connecting portion die cavity 2121 communicate to the thickness of outward appearance board die cavity 211 is greater than connecting portion die cavity 2121's thickness, thereby is favorable to guaranteeing the stability that the material flows at outward appearance board die cavity 211, thereby reduces the possibility that produces the flow line at outward appearance board 11 outward appearance face 111, improves the yield of product at least to a certain extent, satisfies user's user demand.
