DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1

[0022] A refrigerator door seal automatic positioning pressing and moulding device, such as Figures 1 to 3 As shown, it includes a bracket 11, on which a door seal guide positioning device, a door seal pressing device, a mold penetration device and a magnetic strip positioning device are provided, wherein:

[0023] The door seal guide positioning device comprises a door seal positioning groove 101. The refrigerator door seal is introduced into the door seal positioning groove 101 through a conveying device. The door seal can move in the door seal positioning groove 101 along the mold penetration direction.

[0024] The door seal clamping device includes a movable pressure block 31, a fixed pressure block 32, a movable pressure block claw 33, a pin 34, a clamping device bracket 36, a reset spring 37 and a rotary clamping cylinder 38. The movable pressure block claw 33 is fixed to the top of the cylinder shaft 35 of the rotary clamping cylinder 38. The movable pressure block 31 is sleeved outside the cylinder shaft 35 of the rotary clamping cylinder 38. The pin 34 is inserted into the pin hole at one end of the movable pressure block 31. The movable pressure block claw 33 moves the movable pressure block 31 through the pin 34. The movable pressure block 31 has two claws. When the movable pressure block 31 moves downward, the claws of the movable pressure block 31 cooperate with the fixed pressure block 32 to clamp the door seal in the door seal positioning groove 101. The fixed pressure block 32 is located below the door seal positioning groove 101, and the movable pressure block 31 is located above the door seal positioning groove 101. The clamping device bracket 36 described in the rotary clamping cylinder 38 is fixed.

[0025] The mold-piercing device inserts the door seal strip after positioning and clamping into the welding mold. The mold-piercing device includes a guide rail 41, a slider 42 and a mold-piercing cylinder 43. The guide rail 41 and the slider 42 form a guiding mechanism. The mold-piercing cylinder 43 pushes the slider 42 to slide along the guide rail 41. The clamping device bracket 36 in the door seal strip clamping device is fixed to the slider 42.

[0026] The magnetic stripe positioning device is mainly used to determine the position of the magnetic stripe in the door seal. The magnetic stripe positioning device includes a door seal limit device and a yielding device. The door seal limit device includes a limit rod 51 and a magnetic stripe limit block 52. The magnetic stripe limit block 52 is located at the opening of the door seal positioning groove 101. The yielding device includes a connecting pressure rod 53, a pressure block 54, a force transmission rod 55, an oblique pressure block 56, a connecting pressure rod reset spring 57 and a spring fixing pin 58.

Figure 4 , a downward pressing portion is also provided outside the cylinder shaft 35 of the rotary clamping cylinder 38, and a pressing block 54 is located below the downward pressing portion. When the door seal moves to the limit rod 51, the magnetic limit block 52 ensures the position of the door seal. After the magnetic limit is completed, the door seal is pressed against the fixed pressure block 32 by the movable pressure block 31, and the door seal is inserted into the welding mold under the action of the mold insertion device. However, before the mold insertion, the limit rod 51 and the magnetic limit block 52 need to give up the mold insertion position. Figure 4 , Figure 5 As shown in the figure, the two ends of the force transmission rod 55 are respectively connected to the pressure block 54 and the inclined pressure block 56, the connecting pressure rod 53 is located below the inclined pressure block 56, and the bracket 11 is provided with a connecting pressure rod slide groove 102. The connecting pressure rod 53 moves along the connecting pressure rod slide groove 102 of the bracket, and the two ends of the connecting pressure rod reset spring 57 are respectively connected to the connecting pressure rod 53 and the spring fixing pin 58. This device adopts the same rotary clamping cylinder 38 to achieve the limiting and pressing of the door seal. When the rotary clamping cylinder 38 starts to work, the movable pressure block 31 first rotates to the pressing position under the action of the push pin 34, and at the same time, the cylinder shaft of the rotary clamping cylinder 38 rotates and descends, and the pressing part presses the pressure block 54, and the pressure block 54 drives the force transmission rod 55 and the inclined pressure block 56 to press down the connecting pressure rod 53, and the connecting pressure rod 5 moves along a fixed trajectory in the connecting pressure rod slide groove 102 of the bracket 11. The door seal limit block 51 moves backward and downward along a certain trajectory to make way for the door seal. After the rotary clamping cylinder 38 moves a certain distance axially downward, when the push pin 34 presses the movable pressure block 31, the movable pressure block 31 starts to descend and press the door seal.

[0027] In this embodiment, the door seal strip positioning groove includes an upper positioning groove and a lower positioning groove. A movable pressure block 31 is respectively provided above each upper positioning groove. The two movable pressure blocks 31 are fixedly connected by a sleeve. The sleeve is sleeved outside the cylinder shaft of the rotary clamping cylinder 38. A fixed pressure block 32 is respectively provided below each lower positioning groove, and the number of magnetic strip limit blocks 52 is also 2.

[0028] In this embodiment, the door seal strip positioning groove includes a front positioning block and a rear positioning block, a support strip 103 is provided on the bracket 11, the front positioning block and the rear positioning block are vertically arranged on the support strip 103, a plurality of bolt holes 104 are provided on the support strip 103, and the front positioning block, the rear positioning block and the support strip 103 are connected by bolts. The bolt holes 104 on different support strips 103 can be adjusted to connect with the front positioning block and the rear positioning block, so as to adapt to door seal strips of different widths.
