[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] like Figure 1As shown, an embodiment of this application provides a folding mold transfer arm, which includes two spaced-apart mold transfer arm assemblies 100. Each mold transfer arm assembly 100 includes a base 101. A first conveying arm 102 is hinged to the upper end of the base 101. One end of the first conveying arm 102 away from the base 101 is hinged to a middle support leg 105. A movable support leg 106 is spaced apart on one side of the middle support leg 105. A second conveying arm 103 is disposed between the middle support leg 105 and the movable support leg 106. One end of the second conveying arm 103... The first conveying arm 102 is hinged to the middle support leg 105, and the other end of the second conveying arm 103 is hinged to the movable support leg 106. A drive cylinder 104 is hinged between the end of the first conveying arm 102 near the base 101 and the lower end of the base 101. Several spaced-apart first-type connecting rods 107 connect the two first conveying arms 102, several spaced-apart second-type connecting rods 108 connect the two second conveying arms 103, a first-type crossbar 109 connects the two middle support legs 105, and a second-type crossbar 110 connects the two movable support legs 106. It also includes a first auxiliary linkage frame 111, one end of which is hinged to each of the two bases 101, and the other end of which is hinged to each of the two middle support legs 105. Similarly, it also includes a second auxiliary linkage 112, one end of which is hinged to two middle support legs 105, and the other end of which is hinged to two movable support legs 106.

[0034] Specifically, both the first conveying arm 102 and the second conveying arm 103 mentioned above are roller-type conveying arms, that is, they are equipped with multiple rollers.

[0035] Specifically, the aforementioned auxiliary linkage frame may include two longitudinal rods 1111 and two transverse rods 1112. When the folding mold-shifting arm is in the unfolded position, the end of the first auxiliary linkage frame 111 connected to the base 101 is higher than the end of the first auxiliary linkage frame 111 connected to the middle support leg 105, and the end of the second auxiliary linkage frame 112 connected to the movable support leg 106 is higher than the end of the second auxiliary linkage frame 112 connected to the middle support leg 105.

[0036] Specifically, such as Figure 1As shown, the lower end of the aforementioned drive cylinder 104 is hinged to the base 101, and the piston rod of the drive cylinder 104 is hinged to the first conveying arm 102 via a connecting piece. When the folding mold-moving arm is in the unfolded position, the first conveying arm 102 and the second conveying arm 103 remain horizontal, and the base 101, the middle support leg 105, and the movable support leg 106 are spaced a large distance apart. When it is necessary to fold and retract the folding mold-moving arm, the drive cylinder 104 pushes one end of the first conveying arm 102, causing the first conveying arm 102 to rotate. The end of the first conveying arm 102 away from the base 101 gradually rises, thereby causing the middle support leg 105 to rise and gradually reducing the distance between the middle support leg 105 and the base 101. At the same time, the end of the second conveying arm 103 adjacent to the first conveying arm 102 also gradually rises, and the distance between the movable support leg 106 and the middle support leg 105 gradually decreases. Finally, as shown... Figure 7 As shown, the folding mold-moving arm folds and retracts.

[0037] In one embodiment, the lower end of the middle support leg 105 is provided with a height adjustment component.

[0038] Specifically, there are various implementations of the height adjustment component. For example, the height adjustment component includes a threaded rod 118 threadedly connected to the middle support leg 105. A base 117 is provided at the lower end of the threaded rod 118, and a locking nut 119 is provided on the threaded rod 118. By rotating the threaded rod 118, the height of the base 117 can be adjusted so that when the folding mold-moving arm is in the unfolded posture, the base 117 is in contact with the ground. After the locking nut 119 is loosened, the threaded rod 118 can rotate relative to the middle support leg 105. After the locking nut 119 is tightened, the threaded rod 118 is fixed.

[0039] In one embodiment, the movable support leg 106 includes a main body and a walking component disposed at the bottom of the main body.

[0040] Based on the above, the walking assembly includes a support 121 and a plurality of walking wheels 122 disposed on the support 121.

[0041] By setting the walking wheels 122, the moving support legs 106 can move more smoothly, making it easier for the folding mold-moving arm to quickly unfold and retract.

[0042] In one embodiment, an extension platform 113 is provided on the upper end of the base 101, and a pin seat 114 is provided on the extension platform 113. A pin 116 is provided in the pin seat 114, and a pin cylinder 115 is connected to one side of the pin seat 114. The piston rod of the pin cylinder 115 is connected to the pin 116. A pin hole 1021 is provided on the first conveying arm 102, and the pin cylinder 115 is used to drive the pin 116 to be inserted into the pin hole 1021.

[0043] Specifically, when the folding transfer arm is folded and retracted, the pin hole 1021 on the first conveyor arm 102 rotates with the first conveyor arm 102 until it aligns with the pin 116. At this time, the pin cylinder 115 drives the pin 116 to extend and insert into the pin hole 1021, thus locking the first conveyor arm 102 and preventing it from moving. When the pin 116 is removed from the pin hole 1021, the first conveyor arm 102 can move. When the folding transfer arm is fully extended, the pin hole 1021 moves away from the pin 116, and the pin 116 cannot be inserted into the pin hole 1021.

[0044] In one embodiment, guide blocks 120 are provided on the outer side of the first conveying arm 102 and the outer side of the second conveying arm 103.

[0045] Specifically, the orientation of the mold can be corrected through the aforementioned guide block 120.

[0046] An embodiment of this application also provides a mold changing assembly, which includes a machine base 201, which may be a machine base 201 on a press. A support base 202 is provided on the machine base 201 for supporting the mold. It also includes the aforementioned folding mold-moving arm. The folding mold-moving arm is provided on one side of the machine base 201, and its base 101 is connected to one side wall of the machine base 201. A first chain track 206 and a second chain track 203 are respectively provided on both sides of the support base 202 on the table surface of the machine base 201. An auxiliary mold-moving arm 204 is provided on the outer side of 3. The auxiliary mold-moving arm 204 is used to dock with the folding mold-moving arm. A hook 207 is provided on the first chain track 206. A push-pull assembly 208 connected to the first chain track 206 is provided on one side of the hook 207. The push-pull assembly 208 is also connected to the hook 207. The push-pull assembly 208 is used to drive the hook 207 to move. An intermediate chain track 205 is also provided on the support base 202. The intermediate chain track 205 is used to dock with the first chain track 206 and the second chain track 203.

[0047] Specifically, the aforementioned push-pull assembly 208 is a prior art push-pull assembly 208, generally including a motor, transmission components, and chains. After the push-pull assembly 208 drives the hook 207 to pass sequentially through the first chain track 206, the intermediate chain track 205, and the second chain track 203, the hook 207 hooks onto the mold located on the folding mold-moving arm. Then, the push-pull assembly 208 drives the hook 207 to move in the opposite direction, pulling the mold onto the support base 202.

[0048] Specifically, when it is necessary to push the mold of the support base 202 onto the folding mold transfer arm, the push-pull assembly 208 drives the hook 207 to move and hook the mold. Then, the push-pull assembly 208 drives the hook 207 to move, and pushes the mold onto the folding mold transfer arm through the hook 207.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
