They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directions should not be interpreted as restrictive terms.

[0032] The present application embodiment discloses a clamping tool for a drop molding machine. Figure 1 and Figure 2 The clamping tool for the drop molding machine includes a base plate 1, which is arranged in a rectangular parallelepiped shape. The base plate 1 is horizontally installed on the machine platform, and a first positioning rod 2 and a second positioning rod 3 are fixed on the upper surface. The first positioning rod 2 and the second positioning rod 3 are perpendicular to each other, wherein the first positioning rod 2 is fixed to the upper edge of the base plate 1 and is arranged along the length direction of the base plate 1, and the second positioning rod 3 is fixed to the middle part of the base plate 1 and is arranged along the width direction of the base plate 1.

[0033] At the same time, a carrier frame 4 is placed on the substrate 1, and the carrier frame 4 is used to carry the mold. The carrier frame 4 includes a frame body 41 and a carrier plate 42. The carrier plate 42 is arranged on the frame body 41, and a placement groove 421 is opened on the upper surface of the carrier plate 42. The frame body 41 is arranged in a rectangular shape, and two adjacent side walls of the frame body 41 are respectively abutted and cooperated with the first positioning rod 2 and the second positioning rod 3.

[0034] Furthermore, a pressing assembly 5 is also provided on the base plate 1 , and the pressing assembly 5 applies a force on the supporting frame 4 toward the first positioning rod 2 and the second positioning rod 3 .

[0035] Therefore, the mold is placed on the carrier 4, and the two adjacent side walls of the carrier 4 are respectively abutted against the first positioning rod 2 and the second positioning rod 3, ensuring the correct positional relationship between the mold and the positioning rods when placed, avoiding the displacement or misalignment of the mold, and the clamping assembly 5 applies a force to the carrier 4 toward the first positioning rod 2 and the second positioning rod 3, so that the mold is more firmly positioned during the placement process, reducing the movement or shaking of the mold during operation.

[0036] Correspondingly, the clamping assembly 5 includes a clamping cylinder 51 and a push block 52. The clamping cylinder 51 is arranged on the substrate 1. The piston rod of the clamping cylinder 51 is inclined toward the angle formed by the first positioning rod 2 and the second positioning rod 3. The push block 52 is fixed to the end of the piston rod of the clamping cylinder 51. The push block 52 and the piston rod of the clamping cylinder 51 are perpendicular to each other. After the frame 41 is placed on the substrate 1, the side wall of the push block 52 abuts against the edge of the frame 41 away from the angle formed by the first positioning rod 2 and the second positioning rod 3.

[0037] Therefore, after the frame 41 is placed, the pressing cylinder 51 is started, and the piston rod of the pressing cylinder 51 moves, thereby driving the push block 52 to move toward the supporting frame 4, and then being able to apply a force to the frame 41 close to the first positioning rod 2 and the second positioning rod 3, thereby improving the stability of the placement of the frame 41.

[0038] Furthermore, an adjustment groove 511 is provided on the surface of the clamping cylinder 51, and the adjustment groove 511 is arranged along the length direction of the clamping cylinder 51.

The adjustment bolt 512 and the adjustment groove 511 slide relative to each other, and the adjustment bolt 512 is threadedly connected to the base plate 1, and the adjustment bolt 512 abuts against the side wall of the clamping cylinder 51.

[0039] Therefore, the operator rotates the adjusting bolt 512 to separate the adjusting bolt 512 from the clamping cylinder 51, and then can relatively adjust the position of the clamping cylinder 51. Specifically, the angle of the clamping cylinder 51 is rotated or the relative position of the adjusting bolt 512 in the adjusting groove 511 is changed, thereby changing the position of the push block 52 to adapt to different sizes of carrier frames 4 and improve applicability.

[0041] In addition, a plurality of diversion air holes 13 are provided on the upper surface of the substrate 1, and a main air hole (not shown in the figure) is provided on the side wall of the substrate 1. The plurality of diversion air holes 13 are connected to the main air hole, and the main air hole is externally connected to an air supply device. In the present embodiment, the air supply device adopts an air pump, and the main air hole is evacuated by the air pump so that the diversion air holes 13 provide a negative pressure, thereby adsorbing the carrier 4, and further providing stability for the placement of the carrier 4.

[0042] On the other hand, the frame 41 is arranged in a ring shape, that is, the upper and lower surfaces of the frame 41 are both opened, and a mounting frame 411 is fixed to the inner wall of the frame 41. The mounting frame 411 is composed of a plurality of rods. A sphere 412 is fixed to the middle of the mounting frame 411. Correspondingly, a groove (not shown in the figure) is opened on the lower surface of the supporting plate 42, and the groove corresponds to half covering the outer side of the sphere 412, and the sphere 412 can rotate relative to the groove, thereby realizing a spherical hinge between the supporting plate 42 and the frame 41.

[0043] At the same time, a limiting rod 413 is slidingly provided on the side wall of the frame 41, and the limiting rod 413 is horizontally arranged. A limiting groove 422 is provided on the side wall of the supporting plate 42, and the limiting rod 413 is plugged into and matched with the limiting groove 422. The supporting plate 42 is used to support the mold. Specifically, a positioning groove is provided on the upper surface of the supporting plate 42, and the shape and size of the positioning groove match the mold.

[0044] Therefore, after the plastic dripping is completed, the limiting rod 413 is pulled out from the limiting groove 422, and the operator controls the support plate 42 to rotate so that the plastic in the mold can flow more quickly and cover the mold, thereby indirectly improving the plastic dripping efficiency.

[0045] Furthermore, a guide surface is provided at the end of the limit rod 413, and the guide surface is specifically an arc surface. Accordingly, the guide surface design at the end of the limit rod 413 helps to ensure accurate positioning during the plug-in process, thereby improving the accuracy and stability of the limit rod 413 during plug-in and limit operation.

[0046] In addition, a gripping portion 423 is fixed to the upper surface of the supporting plate 42 , and the gripping portion 423 is vertically fixed to the upper surface of the supporting plate 42 . The operator can more conveniently control the rotation of the supporting plate 42 by gripping the gripping portion 423 , thereby improving the convenience of operation.
