Through the structure of the dishwasher liner shown in Figures 1 to 7, specifically, what the pre-assembled mold provided by the embodiment of the present invention is to solve is the connection (riveting) between the middle plate, the top plate and the bottom plate Therefore, in the embodiment of the present invention, the middle plate, the top plate and the bottom plate are regarded as a flat plate structure of the base plate, and only the structural features of their joints are reserved for the convenience of description. Correspondingly, the positioning surface mentioned above specifically refers to a plane in space, specifically, the inner wall of the middle plate (the inner wall of the side plate of the first middle plate, the inner wall of the side plate of the second middle plate, the inner wall of the top plate of the middle plate) Inner wall) overlaps with the third positioning surface 193, the fourth positioning surface 194 and the fifth positioning surface 195 respectively; After the overlapping relationship between the above positioning surface and the corresponding inner wall, the relative position of the lower flange surface of the middle plate and the bottom flange surface of the bottom plate meets the pre-assembly requirements, and the upper flange surface of the middle plate and the top flange surface of the top plate meet the pre-assembly requirements.

Basically, the pre-assembled mold includes an adjustment device, a bottom plate mold assembly 103 and a top plate mold assembly 104;

The bottom plate mold assembly 103 is arranged on the mold support 101;

The adjustment device includes an adjustment driver 114, the body of the adjustment driver 114 is fixed on the mold support 101, and the top plate mold assembly 104 is arranged on the driving end of the adjustment driver 114;

The first positioning surface 191 is established based on the bottom plate mold assembly 103, the second positioning surface 192 is established based on the top plate mold assembly 104, and the distance between the second positioning surface 192 and the first positioning surface 191 The distance is adjusted via the drive end of the adjustment drive 114 .

Specifically, the impact of the middle plates of different heights (x-direction dimensions) on the pre-assembly of the dishwasher liner mainly affects the distance between the top plate and the bottom plate of the dishwasher liner during pre-assembly. The spacing between the bottom plates is controlled by the spacing between the first positioning surface 191 and the second positioning surface 192. Therefore, the pre-assembled mold provided by the embodiment of the present invention consists of the first positioning surface 191 in the bottom plate mold assembly 103 area, The second positioning surface 192 is established by the top plate mold assembly 104. Under the control of the adjusting device (essentially, the adjustment driver 114), the bottom plate mold assembly 103 is fixed relative to the mold support 101, and the top plate mold assembly 104 is driven relative to the adjustment driver 114. The ends are fixed, and the distance between the top plate mold assembly 104 and the bottom plate mold assembly 103 can be adjusted under the drive of the adjustment driving member 114, so as to achieve the purpose of adjusting the distance between the first positioning surface 191 and the second positioning surface 192.

Correspondingly, the driving end of the air cylinder generally has two positioning positions. Correspondingly, the pre-assembled mold using the air cylinder as the adjustment driving part 114 can be adapted to two heights of the middle plate, that is, to realize the adjustment of the two types of dishwasher inner tanks. pre-assembled. Specifically, by replacing the middle plate of two heights, the height of the dishwasher liner can be 775 mm and 815 mm.

Specifically, for the specific formation of the first positioning surface 191 and the second positioning surface 192, the base plate mold assembly 103 includes a base plate mold driving part 122 and a base plate suction cup device, and the body of the base plate mold driving part 122 is fixed on the On the mold support 101, the driving end of the bottom plate mold driving member 122 moves along the first axis direction, the bottom plate sucker device is arranged on the driving end of the bottom plate mold driving member 122, and on the bottom plate mold driving member 122 When the driving end moves to the end of the stroke in the positive direction of the first axis, the side of the bottom plate suction cup device away from the top plate mold assembly 104 establishes the first positioning surface 191;

Specifically, the bottom plate suction cup device and the top plate suction cup device of the embodiment of the present invention are driven to move in the x direction based on the corresponding mold driving member; since the dishwasher liner needs to be taken out after pre-assembly, in order to avoid the bottom plate suction cup device and the top plate suction cup device It affects the removal of the dishwasher liner. After the bottom plate suction cup device and the top plate suction cup device are positioned on the top plate and the bottom plate, the bottom plate suction cup device and the top plate suction cup device are returned to avoid contact between the bottom plate suction cup device and the bottom plate, and avoid The top plate sucker device is in contact with the top plate, thereby avoiding the impact of the pre-assembled mold on the removal of the dishwasher inner container.

Correspondingly, according to the description of the movement and functions of the bottom plate suction cup device and the top plate suction cup device, the bottom plate suction cup device and the top plate suction cup device only need two position states to meet the implementation requirements. Therefore, based on the implementation cost and implementation convenience In consideration of performance, in the embodiment of the present invention, the bottom plate mold driving part 122 is an air cylinder; and/or the top plate mold driving part 121 is an air cylinder.

In addition, the bottom plate suction cup device or the top plate suction cup device generally also includes corresponding connecting structural parts to meet the fixing and transmission requirements of the suction cups, which can be designed according to actual needs in specific implementation.

It should be noted that the end of the suction cup is generally made of soft material. When the suction cup is working, the end of the suction cup will produce a certain deformation to attach to the object to be adsorbed. It is the working surface of the suction cup.
