Description

Technical Field

[0001] The invention relates to a dishwasher inner tank processing device, in particular to a dishwasher inner tank slide plate type mold core. Background Art

[0002] The traditional dishwasher mold core is an integral mold for the top plate and the bottom plate. The two integral molds are installed on a bracket with a telescopic guide column. When the dishwasher inner tank needs to be bitten, the middle plate is first placed between the top and bottom plate molds. The suction cup adsorbs the middle plate for initial fixation, and then the top plate, bottom plate and middle plate are manually buckled together. The suction cups installed on the top and bottom plates adsorb the top and bottom plates to accurately locate the positions of the top, middle and bottom plates. After manual inspection of the buckling, the biting equipment is used to bite the edges. After the biting is completed, the top plate integral mold is retracted inward along the axis of the middle plate, and the gap between the top and bottom plate molds and the dishwasher inner tank is increased, so that the bitten inner tank can be easily demolded without scratches.

[0003] Traditional dishwasher liner mold cores require manual loading, which is high in labor costs, slow compared to robot loading, and easily scratched during demoulding. In order to improve product quality, increase production efficiency, and save costs, it is necessary to develop a skateboard-type mold core for the liner. The middle mold moves up and down to drive the two side molds to tilt. Both the top and bottom plates use skateboard-type molds, so that robots can be used for loading and unloading. This form does not require workers to load materials, does not require manual inspection of whether the loading is accurately positioned, and there is no scratching when unloading, which greatly improves production efficiency.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] For details, please refer to the new dishwasher liner mold core loading and unloading process Figure 1 (a) and (b) of .

[0028] When the slide-type mold core is in the working state of the dishwasher liner bite, the upper edges of the left mold, the right mold and the middle mold are flush, the joints are smooth and flat, and there is no indentation or misalignment when the dishwasher liner bites. When the mold core is in the state of loading and demoulding the dishwasher liner, the middle slide moves downward, and at the same time drives the slides on both sides to retract downward and inward. After the mold is retracted into place, the left and right sides and the upper side have a gap with the liner, and there is no scratch when loading and demoulding.

[0029] like Figures 2 to 7 As shown, in view of the new loading and unloading process, the present invention proposes a dishwasher inner tank skateboard mold core, which is composed of a suction cup telescopic component 101, a clamping mechanism 102, a skateboard mold component 103, a skateboard lifting and latching mechanism 104, an inner tank mold 105, a frame 106 and an electronic control system.

[0030] The suction cup extension assembly 101 is composed of two suction cup connecting plates 205 arranged symmetrically along the central plane of the bracket 203. Four suction cups 201 are installed on each side of the suction cup connecting plate 205. When the robot places the liner on the mold core, the suction cup 201 sucks the liner and the liner does not fall off. During loading, the cylinder 206 pushes the suction cup 201 to extend. The extended suction cup 201 is very close to the top plate and the bottom plate. The rubber on the suction cup 201 and the liner are vacuum-adsorbed and not separated. After biting, the suction cup 201 is pulled back by the action of the cylinder 206, and the suction cup 201 and the liner are separated, and demoulding is labor-saving and non-interference.

[0031] The clamping mechanism 102 of the mold core is mainly used for tightening and positioning the middle plate after the inner liner is placed on the bracket 203. The clamping cylinder 301 pushes the linear guide 305 forward to drive the pressure plate 306 and the adjustable pressure block 307 to move forward. The lower edge of the adjustable pressure block 307 presses the edge of the inner liner. The upper cylinder 309 pushes the upper copper block 308 to move upward. The edge of the inner liner is sandwiched between the upper copper block 308 and the adjustable pressure block 307, and the positioning is accurate. The pressure of the upper cylinder 309 can ensure that the middle plate does not slip or dislocate.

[0032] The skateboard mold assembly 103 is the key mechanism of the mold core. The tire frame 414 is a component that is machined after welding and annealing steel plates. Bolts are used to connect the pad 402 and the tire frame 414. The pad 402 is hard and wear-resistant, which can ensure the durability of the mold core. The pad 402 is provided with a vertical slide key 401 and an oblique slide key 404 installation groove, and the key is embedded in the pad 402. The middle slide 407 and the side slide 412 have key grooves on the back. The middle slide 407 and the side slide 412 can slide smoothly along the installation direction of the vertical slide key 401 and the oblique slide key 404. When moving up, the middle slide 407 pushes the two side slides 412 to move through the inclined surface, and when moving down, the middle slide 407 pulls the two side slides 412 back through the pull block. The small pressure cover 409 and the large pressure cover 406 are fixed to the pad 402 with bolts to ensure that the middle slide 407 and the side slide 412 do not fall off when sliding up and down and tilting.

[0033] The slide plate lifting and latch mechanism 104 is extended through the hydraulic cylinder 507 installed on the bracket, pushing the connecting shaft 505 and the connecting rod 504 to move up at the same time. The middle of the connecting rod 504 is connected to the connecting shaft 505 of the hydraulic cylinder, and the two sides are symmetrically connected to the lower part of the pull rod 502. The upper part of the pull rod 502 is connected to the middle slide plate 407. When the hydraulic cylinder 507 is extended, the middle slide plate 407 and the two side slide plates 412 are horizontal, and the latch 501 is extended under the thrust of the latch cylinder 503. After the hydraulic cylinder 507 is depressurized, the middle slide plate 407 will not slide downward, which can ensure that there is no indentation when biting. After the biting is completed, the latch cylinder 503 drives the latch 501 to retract, and the hydraulic cylinder 507 indirectly drives the middle slide plate 407 to move down. The inner liner that has been bitten can be demoulded, and the next inner liner can be loaded.

[0034] The inner liner mold 105 provides inner support for the inner liner. The inner mold is a slide plate type mold, which is fixed to the middle slide plate 407 and the side slide plate 412 by bolts.
