[0002] Injection molds are tools used to produce plastic products for the outer shells of small household appliances; they are also tools that give plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and molten plastic into the mold cavity under high pressure by an injection molding machine, and obtaining the molded product after cooling and solidification.

[0003] Existing injection molding molds for home appliance casings are mostly installed and fixed with multiple fixing bolts. When the mold is damaged and needs to be disassembled and repaired, it is not convenient and quick to disassemble and install. The disassembly and installation process is cumbersome and seriously affects the repair efficiency. Utility Model Content

The upper end face of the base and the lower end face of the top plate are respectively provided with a matching lower mold and an upper mold. An installation mechanism is provided between the base and the lower mold and between the top plate and the upper mold.

[0006] The installation mechanism includes cavities formed inside the base and the top plate. The upper end face of the base and the lower end face of the top plate are each provided with multiple evenly distributed through holes. Multiple symmetrically distributed limit blocks in an n-shaped structure are slidably connected to the inner side walls of opposite sides of the two cavities. Multiple evenly distributed pins that match the multiple through holes are fixedly connected to the lower end face of the lower mold and the upper end face of the upper mold. The multiple pins pass through the multiple through holes and extend into the interior of the two cavities. The outer wall of the pins is provided with two symmetrically distributed slots that match the limit blocks. The lower end face of the limit blocks and the lower inner end of the slots are both set as mutually matching inclined structures.

[0007] As a preferred embodiment of the injection molding mold for a household appliance casing according to this utility model, the installation mechanism further includes a screw rotatably connected inside the cavity, a movable plate threadedly connected to the outer wall of the screw, and a connecting rod rotatably connected to the movable plate and multiple limiting blocks via hinge seats.

[0008] As a preferred embodiment of the injection molding mold for a household appliance casing according to this utility model, the lower end face of the base and the upper end face of the top plate are both fixedly connected to mounting boxes. One end of each of the two screws extends into the interior of the two mounting boxes and is fixedly connected to a worm gear. The interior of each of the two mounting boxes is rotatably connected to a worm gear that meshes with the worm gear.

[0009] As a preferred embodiment of the injection molding mold for a household appliance casing according to this utility model, a plurality of evenly distributed electric telescopic rods are installed between the base and the top plate.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-5 An injection molding mold for a household appliance casing includes a base 1 and a top plate 2 distributed vertically. The upper end face of the base 1 and the lower end face of the top plate 2 are respectively provided with a matching lower mold 3 and an upper mold 4. An installation mechanism is provided between the base 1 and the lower mold 3 and between the top plate 2 and the upper mold 4.

[0024] The mounting mechanism includes cavities 5 formed inside the base 1 and the top plate 2. Multiple evenly distributed through holes 6 are formed through the upper end face of the base 1 and the lower end face of the top plate 2. Multiple symmetrically distributed limit blocks 7 with an n-shaped structure are slidably connected to the inner side walls of opposite sides of the two cavities 5. Multiple evenly distributed pins 8 that match the multiple through holes 6 are fixedly connected to the lower end face of the lower mold 3 and the upper end face of the upper mold 4. The multiple pins 8 pass through the multiple through holes 6 and extend into the interior of the two cavities 5. Two symmetrically distributed slots 9 that match the limit blocks 7 are formed on the outer wall of the pins 8. The lower end face of the limit blocks 7 and the lower end of the slots 9 are both set as mutually matching inclined structures.

[0025] In this embodiment: when disassembling the lower mold 3 and the upper mold 4, the fixing state of the installation mechanism on the lower mold 3 and the upper mold 4 is released. Specifically, multiple limiting blocks 7 move in opposite directions, so that the multiple limiting blocks 7 are moved out of the multiple slots 9 respectively, thereby releasing the limiting and fixing state of the multiple limiting blocks 7 on the multiple pins 8. Then, the lower mold 3 and the upper mold 4 are pulled, and the multiple pins 8 are moved out of the multiple through holes 6 respectively through the lower mold 3 and the upper mold 4, thereby completing the disassembly operation of the lower mold 3 and the upper mold 4.

[0026] When installing the lower mold 3 and the upper mold 4, multiple pins 8 are inserted into multiple through holes 6 through the lower mold 3 and the upper mold 4 respectively. Then, multiple limiting blocks 7 move in opposite directions, so that the multiple limiting blocks 7 enter multiple slots 9 respectively. Since the lower end face of the limiting block 7 and the lower end of the slot 9 are both set as matching inclined structures, when the limiting block 7 moves in the slot 9, the characteristics of the inclined structure can push the pins 8 to move, so that the multiple pins 8 drive the lower mold 3 to the base 1 and the upper mold 4 to the top plate 2 to fit tightly. This securely installs and fixes the lower mold 3 and the upper mold 4, thus completing the installation operation of the lower mold 3 and the upper mold 4. This makes it convenient and quick to disassemble and install the lower mold 3 and the upper mold 4. The disassembly and installation process is simple and avoids affecting maintenance efficiency.

[0027] As a technical optimization of this utility model, the installation mechanism also includes a screw 10 rotatably connected inside the cavity 5, a movable plate 11 threadedly connected to the outer wall of the screw 10, and a connecting rod 12 rotatably connected to the movable plate 11 and multiple limit blocks 7 through hinge seats.

[0028] In this embodiment: the screw 10 rotates, the screw 10 drives the moving plate 11 to move, and the moving plate 11, together with multiple connecting rods 12, drives multiple limit blocks 7 to move in opposite directions.

[0029] As a technical optimization of this utility model, the lower end face of the base 1 and the upper end face of the top plate 2 are both fixedly connected to the mounting box 13. One end of each of the two screws 10 extends into the interior of the two mounting boxes 13 and is fixedly connected to the worm gear 14. The interior of each of the two mounting boxes 13 is rotatably connected to the worm 15, which meshes with the worm gear 14.

[0030] In this embodiment: the worm gear 15 rotates, the worm gear 15 drives the worm wheel 14 to rotate, and the worm wheel 14 drives the screw 10 to rotate.

[0031] As a technical optimization of this utility model, a plurality of evenly distributed electric telescopic rods 16 are installed between the base 1 and the top plate 2.

[0032] In this embodiment, multiple electric telescopic rods 16 can drive the top plate 2 and the upper mold 4 to move.

[0033] As a technical optimization of this utility model, a drive motor 17 is installed on the front end face of each of the two mounting boxes 13, and the output ends of the two drive motors 17 are respectively fixedly connected to the two worm gears 15.

[0034] In this embodiment, the worm gear 15 can be rotated by the drive motor 17.

[0035] As a technical optimization of this utility model, the cavity 5 is fixedly connected with two sliding rods 18 that are distributed front and back and slidably connected to the moving plate 11.

[0036] In this embodiment, the two sliding rods 18 can limit the movement of the moving plate 11, so that the moving plate 11 can move smoothly.

[0037] As a technical optimization of this utility model, the limiting block 7 and the cavity 5 are slidably connected by a limiting slider and a limiting groove.

[0038] In this embodiment, the limiting block 7 can be limited by the limiting slider and the limiting groove, so that the limiting block 7 can move smoothly.

[0039] The working principle and usage process of this utility model are as follows: When in use, multiple electric telescopic rods 16 retract, and the top plate 2 and the upper mold 4 move downward through the multiple electric telescopic rods 16, so that the upper mold 4 and the lower mold 3 come into contact. Then, injection molding is performed between the upper mold 4 and the lower mold 3 through the injection pipe on the lower mold 3, thereby completing the injection molding process of the appliance shell.

[0040] When disassembling the lower mold 3 and the upper mold 4, the fixing state of the installation mechanism on the lower mold 3 and the upper mold 4 is released. Specifically, the two drive motors 17 drive the two worm gears 15 to rotate, the two worm gears 15 cooperate with the two worm wheels 14 to drive the two screws 10 to rotate, the two screws 10 drive the two moving plates 11 to move, the two moving plates 11 cooperate with the multiple connecting rods 12 to drive the multiple limit blocks 7 to move in opposite directions, so that the multiple limit blocks 7 are moved out of the multiple slots 9, thereby releasing the limiting and fixing state of the multiple limit blocks 7 on the multiple pins 8. Then, the lower mold 3 and the upper mold 4 are pulled, and the multiple pins 8 are moved out of the multiple through holes 6 through the lower mold 3 and the upper mold 4, thereby completing the disassembly operation of the lower mold 3 and the upper mold 4.

[0041] When installing the lower mold 3 and the upper mold 4, multiple pins 8 are inserted into multiple through holes 6 through the lower mold 3 and the upper mold 4 respectively. Then, the above steps are reversed to move multiple limit blocks 7 in opposite directions, so that the multiple limit blocks 7 enter multiple slots 9 respectively, thereby completing the installation operation of the lower mold 3 and the upper mold 4.
