[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0036] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the molding die 1 provided in the embodiment of the present application. Figure 2 An exploded schematic diagram of the molding die 1 provided in an embodiment of the present application.

[0037] An embodiment of the present application provides a molding mold 1 for molding a barrel body of a washing machine (not shown). The barrel body of the washing machine, such as an outer barrel, may include a rear outer barrel and a front outer barrel, wherein the rear outer barrel is a portion provided with a barrel bottom, and the front outer barrel is a portion provided with a barrel mouth. This specification takes a molding mold for molding a rear outer barrel as an example. Those skilled in the art can understand that the molding mold for molding a front outer barrel has the same implementation principle as the molding mold for molding the rear outer barrel. Therefore, the description of the molding mold for the rear outer barrel in the specification of this application is also applicable to the molding mold for molding the front outer barrel.

[0038] The molding die 1 provided in the embodiment of the present application can be used to mold a washing machine barrel body of at least one structural strength. Specifically, the molding die 1 includes a fixed die 10 and a movable die 20.

The movable die 20 is arranged opposite to the fixed die 10, and the movable die 20 can move close to or away from the fixed die 10. The movable die 20 includes a movable die frame 21 and a plurality of sets of insert modules, each set of insert modules includes a movable die insert 222 and a side die insert 232, the side die insert 232 surrounds the movable die insert 222, the movable die insert 222 is arranged on the movable die frame 21 for molding the inner cavity of the barrel body, and the side die insert 232 is arranged on the movable die frame 21 and can move relative to the movable die frame 21 for molding the outer wall of the barrel body. Among them, multiple sets of insert modules are selectively installed on the movable mold frame 21 for forming the barrel body, and different insert modules are used to form different barrel bodies. The molding mold of the present application is provided with multiple sets of insert modules, and multiple sets of insert modules are selectively installed on the movable mold frame 21 for forming the barrel body, and different insert modules are used to form different barrel bodies. Therefore, the molding mold 1 can form different washing machine barrel bodies by only replacing different insert modules, so as to meet the fine-tuning and matching of the structural features such as size and shape of the washing machine barrel bodies with different strength requirements. Such a design can greatly reduce the manufacturing cost and shorten the manufacturing cycle.

[0039] In order to better understand the implementation scheme of the embodiment of the present application, the molding mold provided by the embodiment of the present application is further introduced below. For the convenience of description, this specification schematically describes an embodiment in which the molding mold has two insert modules (that is, two movable mold inserts 222 and two side mold inserts 232). Those skilled in the art can understand that the implementation principle of the embodiment with other numbers of insert modules is the same as that with two insert modules, so the description of this specification is also applicable to the case with more insert modules.

[0040] See also Figure 1 and Figure 2The movable mold 20 may further include a movable mold core 22, which is used for forming the inner cavity structure of the outer barrel after molding. Specifically, the movable mold core 22 includes a movable insert seat 221 and the multiple sets of movable mold inserts 222. The movable mold frame 21 is provided with a cavity 200 on one side facing the fixed mold 10. The movable insert seat 221 is assembled in the cavity 200. The movable insert seat 221 is provided with a movable insert position. One of the multiple sets of movable mold inserts 222 in the multiple sets of insert modules is selected and embedded in the movable insert position. The movable mold 20 may further include a side mold 23 (also referred to as a slider in some embodiments), and the side inlay is used to form the outer surface of the barrel wall of the outer barrel. Specifically, the side mold 23 may include a side inlay seat 231 (also referred to as a slider in some embodiments), and the multiple sets of side mold inserts 232. The movable mold frame 21 is provided with a slide groove 210 extending toward the movable mold insert 222 on one side of the fixed mold 10. The side inlay seat 231 is assembled in the slide groove 210. The side inlay seat 231 is provided with a side inlay position. One of the multiple sets of side mold inserts 232 in the multiple sets of insert modules is selected and embedded in the side inlay position.

[0042] Specifically, the movable mold core 22 is constructed to have a shape that is compatible with the desired inner cavity structure of the rear outer barrel. For example, the movable mold core 22 can have an inner cavity diameter, inner cavity axial diameter, and side curvature that are compatible with the inner cavity of the rear outer barrel, as well as a concave-convex structure with holes, grooves, ribs and other features corresponding to the inner cavity of the rear outer barrel. The movable mold core 22 may include a movable insert 221, which is detachably assembled in the mold cavity 200. The movable insert 221 is provided with a movable insert position, and a first movable mold insert 2221 and a second movable mold insert (not shown) are selectively embedded in the movable insert position, wherein the first movable mold insert 2221 can be used to form an inner cavity structure of the rear outer barrel that meets one strength requirement when it cooperates with the movable insert 221, and the second movable mold insert can be used to form an inner cavity structure of the rear outer barrel that meets another strength requirement when it cooperates with the movable insert 221. The side mold 23 is constructed to have a shape that matches the desired outer side structure of the rear outer barrel. For example, the side mold 23 may have a side curvature that matches the outer side of the rear outer barrel, and a concave-convex structure having holes, grooves, ribs and other features corresponding to the outer side of the rear outer barrel. The side mold 23 may include a side insert seat 231 (also called a slide seat in some embodiments), and the side insert seat 231 is slidably assembled in the slide groove 210 so that the side mold 23 can move closer to or away from the movable mold core 22. The side insert seat 231 is provided with a side insert position, and a first side mold insert 2311 and a second side mold insert 2312 (not shown in the figure) are selectively embedded in the side insert position, wherein the first side mold insert 2311 can be used to form an outer side structure of the rear outer barrel that meets one strength requirement when it cooperates with the side insert seat 231, and the second side mold insert 2312 can be used to form an outer side structure of the rear outer barrel that meets another strength requirement when it cooperates with the side insert seat 231.

[0043] In the specific operation, when a rear outer barrel needs to be formed, the first movable mold insert 2221 can be selected to be embedded in the movable insert position of the movable insert seat 221, and then the movable insert seat 221 embedded with the first movable mold insert 2221 is assembled to the mold cavity 200 of the movable mold frame 21, and then the first side mold insert 2311 is selected to be embedded in the side insert position of the side insert seat 231, and finally the side insert seat 231 embedded with the first side mold insert 2311 is assembled to the movable mold frame 21. When another type of rear outer barrel is to be formed, the second movable mold insert can be embedded in the movable embedding position of the movable embedding seat 221, and then the movable embedding seat 221 embedded with the second movable mold insert can be assembled in the cavity 200 of the movable mold frame 21, and then the second side mold insert 2312 can be embedded in the side embedding position of the side embedding seat 231, and finally the side embedding seat 231 embedded with the second side mold insert 2312 can be assembled in the groove 210 of the movable mold frame 21.

[0044] See also Figures 3 to 5 , Figure 3 This is a schematic diagram of the structure of the first movable mold core 22 provided in the embodiment of the present application. Figure 4 This is an exploded schematic diagram of the first movable mold core 22 provided in the embodiment of the present application. Figure 5 A schematic structural diagram of a second movable mold core 22 provided in an embodiment of the present application.

[0045] In some embodiments, the molding mold may include multiple movable inserts, one of which is selectively assembled in the mold cavity 200, and different types of movable inserts are correspondingly assembled with movable mold inserts 222 in different sets of insert modules. The side mold 23 may also include multiple side inserts, one of which is selectively assembled in the slide groove 210, and different types of side inserts are correspondingly assembled with side mold inserts 232 in different sets of insert modules.

[0046] Exemplarily, the movable insert seat may include a first movable insert seat 223 and a second movable insert seat 224, wherein the first movable insert seat 223 is provided with a first movable insert position 2231, and the first movable mold insert 2221 is embedded in the first movable insert position 2231, and the second movable insert seat 224 is provided with a second movable insert position, and the second movable mold insert 2222 is embedded in the second movable insert position. In other words, the first movable insert seat 223 and the second movable insert seat 224 are two independent movable insert seats, and in order to adapt to the structure of the first movable mold insert 2221, the first movable insert seat 223 may be provided with a first movable insert position 2231 corresponding to the first movable mold insert 2221, and the first movable mold insert 2221 is embedded in the first movable insert position 2231, and similarly, in order to adapt to the structure of the second movable mold insert 2222, the second movable insert seat 224 may be provided with a second movable insert position corresponding to the second movable mold insert 2222, and the second movable mold insert 2222 is embedded in the second movable insert position.

[0047] In the embodiment of the present application, by designing a first movable insert 223 for embedding the first movable mold insert 2221, and a second movable insert 224 for embedding the second movable mold insert 2222, when it is necessary to form a rear outer barrel of one strength, it is only necessary to assemble the first movable insert 223 pre-embedded with the first movable mold insert 2221 into the cavity 200 of the movable mold frame 21; when it is necessary to form a rear outer barrel of another strength, it is only necessary to assemble the second movable insert 224 pre-embedded with the second movable mold insert 2222 into the cavity 200 of the movable mold frame 21. Compared with the implementation method in which the first movable mold insert 2221 and the second movable mold insert 2222 share a movable mold seat 221, the cavity 200 assembled on the movable mold frame 21 reduces the operating steps of removing the first movable mold insert 2221 from the movable mold seat 221 before assembling the second movable mold insert 2222, or removing the second movable mold insert 2222 from the movable mold seat 221 before assembling the first movable mold insert 2221, which is beneficial to saving assembly steps and improving mold upper efficiency.

[0048] It should be noted that the first movable mold insert 2221 and the second movable mold insert 2222 can be configured to be used for molding a portion of the rear outer barrel whose size is frequently replaced or changed. It can be understood that in order to facilitate the molding of the inner cavity structure of the rear outer barrel, the first movable mold insert 2221 may include a plurality of first movable mold blocks 22211, and the structure, size, combination and distribution of the plurality of first movable mold blocks 22211 may depend on but not limited to the desired inner cavity structure of one of the rear outer barrels and the characteristics of the injection molding material. Similarly, the second movable mold insert 2222 may include a plurality of second movable mold blocks 22221, and the structure, size, combination and distribution of the plurality of second movable mold blocks 22221 may depend on but not limited to the desired inner cavity structure of another rear outer barrel and the characteristics of the injection molding material, thereby facilitating the maintenance and care of the inserts, and adapting to the structural adjustments made to the rear outer barrel due to strength requirements or functional upgrades of the washing machine.

Figure 7 An exploded schematic diagram of the first sub-side mold provided in an embodiment of the present application, Figure 8 A schematic structural diagram of the second side mold 23 provided in an embodiment of the present application.

[0050] Exemplarily, the side mold 23 may include a first side insert seat 233 and a second side insert seat 234, wherein the first side insert seat 233 is provided with a first side insert position 2331, and the first side mold insert 2311 is embedded in the first side insert position 2331, and the second side insert seat 234 is provided with a second side insert position, and the second side mold insert 2312 is embedded in the second side insert position. In other words, the first side insert seat 233 and the second side insert seat 234 are two independent side insert seats, and in order to adapt to the structure of the first side mold insert 2311, the first side insert seat 233 may be provided with a first side insert position 2331 corresponding to the first side mold insert 2311, and the first side mold insert 2311 is embedded in the first side insert position 2331, and similarly, in order to adapt to the structure of the second side mold insert 2312, the second side insert seat 234 may be provided with a second side insert position corresponding to the second side mold insert 2312, and the second side mold insert 2312 is embedded in the second side insert position.

[0051] The embodiment of the present application designs a first side insert seat 233 for embedding the first side mold insert 2311 and a second side insert seat 234 for embedding the second side mold insert 2312. When a rear outer barrel of one strength needs to be formed, it is only necessary to assemble the first side insert seat 233 pre-embedded with the first side mold insert 2311 to the slide groove 210 of the movable mold frame 21. When a rear outer barrel of another strength needs to be formed, it is only necessary to assemble the second side insert seat 234 pre-embedded with the second side mold insert 2312 to the slide groove 210 of the movable mold frame 21. Compared with the implementation method in which the first side mold insert 2311 and the second side mold insert 2312 share a side insert seat 231, the slide groove 210 assembled on the movable mold frame 21 reduces the operating steps of removing the first side mold insert 2311 from the side insert seat 231 before assembling the second side mold insert 2312, or removing the second side mold insert 2312 from the side insert seat 231 before assembling the first side mold insert 2311, which is beneficial to saving assembly steps and improving mold upper efficiency.

[0052] It should be noted that the first side mold insert 2311 and the second side mold insert 2312 can be configured to be used for molding a portion of the rear outer barrel whose size is frequently replaced or changed. It can be understood that in order to facilitate the molding of the outer side structure of the rear outer barrel, the first side mold insert 2311 may include a plurality of first side mold blocks 23111, and the structure, size, combination and distribution of the plurality of first side mold blocks 23111 may depend on but not limited to one of the desired outer side structures of the rear outer barrel and the characteristics of the injection molding material. Similarly, the second side mold insert 2312 may include a plurality of second side mold blocks 23121, and the structure, size, combination and distribution of the plurality of second side mold blocks 23121 may depend on but not limited to another desired outer side structure of the rear outer barrel and the characteristics of the injection molding material, thereby facilitating the maintenance and care of the inserts and better adapting to the structural adjustments made to the rear outer barrel due to strength requirements or functional upgrades of the washing machine.

[0053] See also Figure 1 and Fig. 9 , Fig. 9The schematic diagram of the installation of the driving mechanism 40 provided in the embodiment of the present application. The molding die 1 also includes a driving mechanism 40, which is arranged on the fixed mold 10 or the movable mold 20, and the driving mechanism 40 is configured as follows: when the movable mold 20 is close to the fixed mold 10 (in some embodiments, this process is also called "mold closing"), the driving mechanism 40 drives the side mold 23 to slide in the direction of the movable mold core 22; when the movable mold 20 is away from the fixed mold 10 (in some embodiments, this process is also called "mold opening"), the driving mechanism 40 drives the side mold 23 to slide in the direction away from the movable mold core 22. Such a design can make the side mold 23 close to the movable mold core 22 during the mold closing process, so that the side mold 23 can cooperate with the fixed mold 10 and the movable mold 20 to form the rear outer barrel, and make the side mold 23 away from the movable mold core 22 during the mold opening process to facilitate the demolding of the rear outer barrel.

[0054] Exemplarily, the driving mechanism 40 may include a hydraulic cylinder 41 or a pneumatic cylinder (not shown), which is fixed to the movable mold frame 21 and connected to the side mold 23 to drive the side mold 23 to slide. The hydraulic cylinder 41 is a hydraulic actuator that converts hydraulic energy into mechanical energy and can perform linear reciprocating motion, and the pneumatic cylinder is a pneumatic actuator that converts pneumatic energy into mechanical energy and can perform linear reciprocating motion. When the molding mold 1 is closed, the hydraulic cylinder 41 or the pneumatic cylinder performs linear motion toward the movable mold core 22 to drive the side mold 23 to approach the movable mold core 22. When the molding mold 1 is opened, the hydraulic cylinder 41 or the pneumatic cylinder performs linear motion away from the movable mold core 22 to drive the side mold 23 away from the movable mold core 22. In order to enable the side mold 23 to automatically stop at the end of the slide groove 210 when performing linear motion driven by the hydraulic cylinder 41 or the pneumatic cylinder, so as to prevent the side mold 23 from hitting the movable mold core 22 when closing the mold or sliding out of the slide groove 210 when opening the mold, the driving mechanism 40 can also include a first stroke switch 42 and a second stroke switch 43, wherein the first stroke switch 42 can be arranged at one end in the sliding direction of the side mold 23, and the second stroke switch 43 can be arranged at the other end in the sliding direction of the side mold 23, thereby enabling the first stroke switch 42 and the second stroke switch 43 to respectively limit the movement of the side mold 23 at both ends of the sliding direction of the side mold 23, thereby providing better protection for the movable mold core 22, the molded product and the side mold 23.

[0055] Typically, the drive mechanism 40 is also provided with a control system, which can be any suitable existing control system, and the embodiment of the present application does not specifically limit it. The first stroke switch 42 and the second stroke switch 43 are connected to the control system. For example, when the molding mold 1 is closed, the hydraulic cylinder 41 or the pneumatic cylinder drives the side mold 23 to move toward the movable mold core 22 under the control of the control system until the side mold 23 abuts the first stroke switch 42. At this time, the first stroke switch 42 is triggered and feeds back a first electrical signal to the control system. The control system receives the first electrical signal and controls the hydraulic cylinder 4 according to the first electrical signal. 1 or the pneumatic cylinder stops driving the side mold 23 to move, and makes the hydraulic cylinder 41 or the pneumatic cylinder maintain the first response of the pressure holding state. When the molding mold 1 is opened, the hydraulic cylinder 41 or the pneumatic cylinder drives the side mold 23 to move in the direction away from the movable mold core 22 under the control of the control system until the side mold 23 abuts the second stroke switch 43. At this time, the second stroke switch 43 is triggered and feeds back a second electrical signal to the control system. The control system receives the second electrical signal and makes a second response according to the second electrical signal to control the hydraulic cylinder 41 or the pneumatic cylinder to stop driving the side mold 23 to move, and makes the hydraulic cylinder 41 or the pneumatic cylinder maintain the second response of the pressure holding state.

[0056] As one of the alternative embodiments, the driving mechanism 40 may include an inclined guide column (not shown) and an inclined guide hole (not shown), wherein the inclined guide column is fixed to the fixed mold 10, the inclined guide hole is provided in the side mold 23, and the inclined guide column at least partially extends into the inclined guide hole, so that when the inclined guide column and the inclined guide hole slide relative to each other, the inclined guide column can drive the side mold 23 to slide. Usually, the fixed mold 10 includes a fixed mold frame, one end of the inclined guide column is fixed to the fixed mold frame, and the other end is inclined in a direction away from the movable mold core 22, the inclined guide hole is provided in the side insert seat 231, and the axial direction of the inclined guide hole is the same as the axial direction of the inclined guide column. Under normal conditions, the end of the inclined guide column away from the fixed mold frame is at least partially in a state of extending into the inclined guide hole, so that when the molding mold 1 is in the process of mold closing or mold opening, the side insert seat 231 can move along the slide groove 210 toward or away from the movable mold core 22 under the interference of the inclined guide column, thereby cooperating with the movable mold core 22 to form the barrel wall of the rear outer barrel.

[0057] See also Figure 1 and Figure 2In some embodiments, the side mold 23 may include a first sub-side mold 2310, a second sub-side mold 2320, a third sub-side mold 2330 and a fourth sub-side mold 2340 surrounding the movable mold core 22, wherein the first sub-side mold 2310 is arranged opposite to the third sub-side mold 2330, and the second sub-side mold 2320 and the fourth sub-side mold 2340 are arranged opposite to each other. Corresponding to the first sub-side mold 2310, the second sub-side mold 2320, the third sub-side mold 2330 and the fourth sub-side mold 2340, the movable mold frame 21 can be provided with a first slide groove 211, a second slide groove 212, a third slide groove 213 and a fourth slide groove 214. The first sub-side mold 2310 is slidably assembled in the first slide groove 211, the second sub-side mold 2320 is slidably assembled in the second slide groove 212, the third sub-side mold 2330 is slidably assembled in the third slide groove 213, and the fourth sub-side mold 2340 is slidably assembled in the fourth slide groove 214. When the molding mold 1 is closed, the first sub-side mold 2310, the second sub-side mold 2320, the third sub-side mold 2330 and the fourth sub-side mold 2340 can move closer to each other under the action of the driving mechanism 40. When the molding mold 1 is opened, the first sub-side mold 2310, the second sub-side mold 2320, the third sub-side mold 2330 and the fourth sub-side mold 2340 can move away from each other under the action of the driving mechanism 40. This method of dividing the side mold 23 with a larger molding surface into a plurality of sub-side molds with smaller molding surfaces is conducive to reducing the defects caused by the adhesion of the side mold 23 to the barrel wall of the rear outer barrel when the molding mold 1 is opened, thereby reducing the defect rate. It is understandable that the side mold 23 can also include two sub-side molds, which surround the movable mold core 22 and are arranged relatively. Of course, it can also include three sub-side molds or even more sub-side molds. The embodiment of the present application does not specifically limit the number of sub-side molds. The specific number is preferably based on the barrel body being easy to demold and having fewer defects after molding.

[0058] In summary, the beneficial effects of the molding mold provided by the present application are: first, a plurality of insert modules are selectively arranged on the movable mold frame for molding the barrel body, and different insert modules are used to mold different barrel bodies. Therefore, the molding mold can form different washing machine barrel bodies separately by only replacing different insert modules, so as to meet the fine-tuning and matching of the size, shape and other structural characteristics of the outer barrel with different strength requirements. Such a design can greatly reduce the manufacturing cost and shorten the manufacturing cycle; second, the side mold with a larger molding surface is subdivided into a plurality of sub-side molds with smaller molding surfaces, which is conducive to reducing the product defects caused by the adhesion of the side mold to the barrel wall when the molding mold is opened, thereby reducing the defective rate.
