Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] Refrigerators are indispensable equipment in modern homes, and the quality of door liners directly affects the overall performance and service life of refrigerators. Traditional refrigerator door liner production equipment usually adopts supported mold forming technology, which provides support through auxiliary molds to ensure accurate filling and shape retention of plastic materials during the molding process.
[0041] Embodiment 1:
[0042] Inaccurate marking may lead to loose fit between the inner tank and the door frame, thus affecting the sealing of the refrigerator, increasing cold air leakage and reducing energy efficiency. In order to solve the above problems, combined with Figure 1-Figure 4 As shown, the present invention provides a refrigerator door liner production equipment, including a door liner rapid prototyping machine 1, a CNC fully automatic trimming machine 3, a material unloading manipulator 4, a material unloading belt line 5, a waste collection component 6 and a door liner non-supporting mold forming mold 2 for sheet forming;
[0043] In the production process, inaccurate marking will cause difficulties in assembly, and may require additional adjustments or trimming, increasing the production cycle and cost. In order to solve the above problems, the door liner rapid prototyping machine 1 includes a frame 11, in which a loading assembly 12 and a conveying mechanism 13 are installed, and a molding mold table assembly 15 is also installed;
[0044] The manufacturing and maintenance costs of the supporting mold forming mold are high, which may increase the overall production cost. In order to solve the above problem, the door liner non-supporting mold forming mold 2 includes a base 21 installed on the forming mold table assembly 15, and a forming assembly 22 is fixed to the base 21;
[0045] The molding component 22 is composed of a water-gas interface, a molding body, a core-pulling mechanism, and an omega molding sliding mechanism. The door liner non-supporting mold forming mold 2 mainly relies on the finger cylinder to complete the molding of the omega groove, thereby achieving the goal of not adding a supporting mold mechanism, thereby reducing the mold manufacturing cost and the molding equipment cost, and preventing the supporting mold from scratching the molding body to avoid quality damage.

[0049] According to the embodiment, the door liner rapid prototyping machine 1 is equipped with a full-service motor, and the main drive service drives the toothed chain to drag the coil to the heating area, the forming area, and the cutting area according to the length requirements of different products. All service motor parameters are set in advance according to different products, so that one-click change of shape can be achieved, which saves a lot of manpower and material resources, is convenient and fast, and improves work efficiency.
[0050] Embodiment 2:
[0051] After the existing trimming mechanism is molded, there may be a certain error between the mold and the standard part. This error may cause the size of the corners to be inconsistent, that is, the size of some positions may be too large, while the size of other positions may be too small. In this case, if the cutting path of the trimming mechanism is not adjusted, the overall size of the door liner after trimming will be deviated, thereby affecting the quality of the final product. In order to solve the above problems, combined with Figure 4 and Figure 5 As shown, on the basis of embodiment 1, the unloading robot 4 includes a frame 41 arranged on the frame 11, a servo drive mechanism 42 is installed on the frame 41, and a suction cup assembly 43 is installed on the servo drive mechanism 42.

The reciprocating motion is fast and accurate, which improves the working efficiency and saves a lot of manpower.
[0052] During the mold forming process, factors such as material deformation, cooling, and unevenness may cause differences in tolerance from standard parts. In order to solve the above problems, the CNC fully automatic trimming machine 3 includes a lateral moving component 31 installed in the frame 11, and a longitudinal moving component 32 is installed on the lateral moving component 31, and a trimming head assembly 33 is installed on the longitudinal moving component 32.

It can realize arbitrary adjustments under normal cutting conditions, and make online adjustments and compensations according to the real-time status of the product; it can achieve automatic adjustment of the running status of each service according to the data adjusted by the human-machine interface, and realize fully automated production. The equipment has a friendly human-machine interface, simple operation, high degree of automation, and one-key change of type, which saves a lot of manpower and material resources, is convenient and fast, and improves work efficiency.

[0056] Specifically, the waste collection assembly 6 includes a waste box 61 disposed in the frame 11 , and a roller 62 is installed at the bottom of the waste box 61 .
[0057] It can be known from the above embodiments that the coiled material is loaded, and after passing through the heating area of the rapid prototyping machine, the sheet is transported to the molding area, and the sheet is molded after the non-supported molding die rises. When the rapid machine cools the molded door liner, the CNC fully automatic trimming machine 3 trims the door liner along the blade path of the non-supported molding die. The manipulator takes the trimmed door liner out of the equipment and places it on the unloading belt line 5. The door liner is transported to the safe area along the belt line, and the waste edge is transported to the exit along the rapid machine, cut off by the cutting device and collected in the waste box 61. This set of CNC fully automatic trimming process reduces the use of personnel, realizes automated production, and improves production efficiency; the relative size of the door liner omega groove to the edge is completely carried out, which is flexible, saves a lot of manpower and material resources, is convenient and fast, improves operating efficiency and optimizes the qualified rate of the door liner.

When the rapid machine cools the molded door liner, the CNC fully automatic trimming machine 3 trims the door liner along the blade path of the non-supporting molding die. This set of CNC fully automatic trimming technology reduces the use of personnel, realizes automated production, and improves production efficiency; the relative size of the door liner omega groove to the edge is completely mobile, which is flexible, saves a lot of manpower and material resources, is convenient and fast, improves operating efficiency and optimizes the pass rate of the door liner.
