AI Technical Summary
During the tripping process, the cover injection molds of existing washing and mopping integrated machines are prone to fail to trip normally due to the wrapping force of the arc-shaped cover plate and the adsorption force of the flat cover plate, and may cause damage to the cover and reduce the injection molding yield.
A washing and drag integrated machine washing and drag head cover injection mold with an inclined top inner ejection structure is designed. By setting an oblique slide groove and groove on the upper mold core, the sliding block, the elastic member and the protrusion are used to cooperate, so that the oblique top can be matched by the steps, sliding block and elastic member during the ejection process, so that the protrusions are removed from the cover later than the forming mold and are easy to trip.
This design effectively avoids damage caused by wrapping and adsorption during the tripping process, improves the injection molding yield, and makes mold tripping more stable and efficient.

[0001] The utility model relates to the technical field of injection molding, in particular to an injection mold for a mopping and washing head cover of a mopping and washing integrated machine with an inclined ejector inner ejection structure. Background Art
[0002] A mopping and washing integrated machine is a household appliance with mopping and washing functions. The mopping and washing integrated machines on the market usually include a handle, components such as a water tank, a water pump, and a controller provided on the handle, and a mopping and washing head provided at the bottom of the handle. To improve the mopping and washing effect, most mopping and washing heads have rotatable mopping and washing rollers and a cover covering the mopping and washing rollers. Such covers are generally injection molded parts. As shown in Figure 1 and Figure 2 , it has an arc-shaped cover plate 2 and flat cover plates 3 vertically connected to both ends of the arc-shaped cover plate. The cross-section of the inner wall of the arc-shaped cover plate 2 is mostly a minor arc or a semi-circle. During injection molding, the mold for forming the part where the inner wall of the arc-shaped cover plate 2 is vertically connected to the flat cover plate 3 can only be withdrawn inward along the horizontally extending direction of the arc-shaped cover plate 2. However, during this process, affected by the wrapping force of the arc-shaped cover plate 2 and the adsorption force of the flat cover plate 3, the cover 1 is extremely likely to move along with the mold, resulting in failure to be withdrawn. Seriously, it will also cause damage to the cover 1, resulting in a low injection molding yield. Summary of the Utility Model

[0029] Such as Figures 3 to 12As shown in the figure, the injection mold for the mop-washing head cover of the integrated mop-washing machine with an inclined ejector inner ejection structure provided by the present utility model includes an upper template 10 and an inclined ejector 20. Among them, an upper mold core 11 for forming the middle part of the inner wall surface of the cover 1 is embedded in the middle of the upper surface of the upper template 10; the inclined ejector 20 is slidably inserted into an inclined chute 111 opened on the upper mold core 11. The upper end of the inclined ejector 20 is an inclined ejector inner ejection structure 21, and the inclined ejector inner ejection structure 21 is used for forming the left end of the inner wall surface of the cover 1. Specifically, the inclined ejector inner ejection structure 21 includes a forming die 211, a sliding block 212, and an elastic member 213. The forming die 211 is integrally formed with the middle and lower parts of the inclined ejector 20. A groove 214 is provided on the side wall (right side wall) of the forming die 211 facing the upper mold core 11. A through hole 215 penetrating the forming die 211 in the horizontal direction (left and right direction) is opened on the bottom wall of the groove 214. The sliding block 212 is slidably inserted into the groove 214 in a direction close to or away from the upper mold core 11 (left and right direction). A protrusion 216 is provided at the end (left end) of the sliding block 212 away from the upper mold core 11. The protrusion 216 is inserted into the through hole 215. The elastic member 213 is clamped between the bottom wall of the groove 214 and the sliding block 212. A notch extending downward is provided at the upper end of the inclined chute 111, and a step 113 with a vertical surface 112 is formed on the inclined chute 111. The sliding block 212 has a first working position and a second working position. When the sliding block 212 is in the first working position, the end (right end) of the sliding block 212 facing the upper mold core 11 abuts against the vertical surface 112 of the step 113, so that the protrusion 216 protrudes from or is flush with the edge of the through hole 215. When the sliding block 212 is in the second working position, the sliding block 212 disengages from the vertical surface 112 of the step 113, and the elastic member 213 pushes the sliding block 212 to slide in a direction close to the upper mold core 11 (right), so that the protrusion 216 retracts into the through hole 215.

[0032] For the convenience of adjustment and processing, in this embodiment, a thimble rod 217 is inserted through the sliding block 212, and the end of the thimble rod 217 constitutes the protrusion 216. Further, a socket head cap screw 218 for locking the thimble rod 217 is also threadedly connected to the sliding block 212.
[0033] In this embodiment, the elastic member 213 is a compression spring, and a receiving hole 219 for receiving the end of the compression spring is further provided on the end face (left end face) of the sliding block 212 away from the upper mold core 11.
[0034] For the convenience of alignment, further, two positioning grooves 220 are formed in the bottom wall of the groove 214. The positioning grooves 220 penetrate through the forming die 211 in the horizontal direction (left - right direction). A positioning post 221 matching the positioning groove 220 is provided at the end (left end) of the sliding block 212 away from the upper mold core 11, and the positioning post 221 is inserted into the positioning groove 220.
[0035] In this embodiment, the inner ejection structure 21 of the lifter also includes a pressing block 222 connected to the edge of the groove 214 through a locking bolt 224. A part of the pressing block 222 extends into a mating groove 223 provided at the end (right end) of the sliding block 212 facing the upper mold core 11 to prevent the sliding block 212 from disengaging from the groove 214 to the right.
[0036] In this embodiment, a movable groove 12 matching the inclined chute 111 is formed on the bottom surface of the upper template 10. A guiding block 121 is fixedly connected in the movable groove 12. The lifter 20 is slidably inserted through the guiding block 121 obliquely. Further, the bottom of the lifter 20 is rotatably connected to a lifter base 30. The lifter base 30 is fixed on a lifting plate 40. The lifting plate 40 is movably arranged below the upper template 10. When the lifting plate 40 moves upward to disengage the inner ejection structure 21 of the lifter from the cover 1, the upper end of the lifter base 30 extends into the movable groove 12, and a bottom plate 50 is further provided below the lifting plate 40.
