Description

Technical Field

[0001] This utility model relates to the field of automated production, specifically a mold handling device. Background Technology

[0002] In modern industrial production, molds, as an important forming tool, are widely used in various processes such as injection molding, die casting, and food molding. During the production process, molds often need to be handled, such as opening the mold or hoisting the upper and lower molds together after closing them.

[0003] Currently, the above-mentioned handling operations are mostly carried out in the following way: first, the lifting ring is screwed into the threaded hole on the side wall of the mold, and then the lifting equipment such as a crane is connected by a chain or wire rope for transportation. However, when handling molds using this method, manual operation of hooking and unhooking is required, which is not only inefficient but also poses a high safety hazard. Secondly, the mold is prone to shaking during transportation, resulting in poor positioning accuracy, which is difficult to meet the requirements in situations where precise alignment is required. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a mold picking and placing device that enables automatic mold picking and placing, improves production efficiency, ensures operational safety, and guarantees the stability and accuracy of the picking and placing process.

[0005] To achieve the above objectives, the present invention employs a mold handling device, comprising a vertically movable lifting unit. The lower surface of the lifting unit is provided with two sets of opposing clamping mechanisms. Each set of clamping mechanisms includes at least one transverse drive mechanism and a sliding seat. Driven by the transverse drive mechanism, the sliding seat moves along the line connecting the two sets of clamping mechanisms. The side wall of the sliding seat is provided with a clamping part extending towards the other clamping mechanism. The clamping part is adapted to a groove on the mold side wall, with the opening of the groove facing its corresponding clamping mechanism. The lifting unit moves the clamping part to the height of the mold groove, and then the transverse drive mechanism pushes the sliding seat, causing the clamping part to horizontally insert into the groove on the mold side wall for gripping. Reverse movement releases the mold, thus automating the entire mold handling process. This not only significantly improves production efficiency and reduces the safety hazards of manual operation, but also effectively suppresses mold swaying during transport by utilizing the embedded load-bearing structure formed by the clamping part and the groove, providing a stable and reliable guarantee for precise alignment.

[0006] Furthermore, in order to drive the lifting part to move vertically, the upper surface of the lifting part is fixedly connected to the piston rod of the vertical drive mechanism, and the cylinder of the vertical drive mechanism is fixedly mounted on the support.

[0007] Furthermore, the clamping part has two hinged positioning parts at its two ends on the sidewall facing the mold, which can automatically reset. In the normal state, the positioning part and the clamping part form an angle, and the end of the positioning part extends out of the clamping part facing the mold. When the clamping part moves inward into the groove, the positioning part contacts the end face of the groove before the clamping part. Then, as the clamping part continues to move, the positioning part is squeezed and opens outward until it is flush with the clamping part. During the rotation of the positioning part, the outer end faces of the two positioning parts abut against the sidewalls on both sides of the groove, thereby fine-tuning and locking the lateral position of the mold before the clamping action is completed. This effectively reduces the positional deviation accumulated due to the pick-and-place operation and provides a more stable and reliable guarantee for the precise alignment of the mold between processes.

[0008] Furthermore, the clamping part has mounting grooves at both ends of its sidewall facing the mold for mounting the positioning part; the outer end face of the mounting groove and its side facing the mold are open, thereby providing space for the positioning part to swing, and limiting the extreme position of the positioning part's swing by the boundary of the mounting groove. The mounting groove not only provides the necessary space to accommodate the installation and resetting swing of the positioning part, but its groove wall also constitutes a mechanical limit on the rotation angle of the positioning part, ensuring that the positioning part can only open and reset stably and reliably within a preset safe stroke.

[0009] The beneficial effects of this utility model are as follows: The structure is simple. Through the coordinated cooperation of the lifting part and the horizontal drive mechanism, the entire process of mold picking and placing is automated, which not only significantly improves production efficiency but also reduces the safety hazards of manual operation. At the same time, the embedded load-bearing structure formed by the clamping part and the mold groove effectively suppresses mold shaking during the handling process, ensuring the stability and positioning accuracy of the handling, and providing a reliable guarantee for the precise alignment of subsequent processes. This makes it easy to integrate into automated production lines to improve the automation level and overall efficiency of the production process. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0021] Example 1, such as Figures 1 to 5 As shown, this embodiment provides a mold loading and unloading device, including a vertically movable lifting part 1. The upper surface of the lifting part 1 is fixedly connected to the piston rod of a vertical drive mechanism 6. The cylinder of the vertical drive mechanism 6 is fixedly mounted on a rigid support 7. The vertical drive mechanism 6 can be a hydraulic cylinder, an electric push rod, etc., and drives the lifting part 1 and its connected components to move up and down by the extension and retraction of the piston rod. The support 7 can be set on a mounting frame and move under the action of existing drive mechanisms such as linear modules. Guide posts 10 are spaced apart on the upper surface of the lifting part 1, and the guide posts 10 and the guide sleeves 11 on the support 7 form a sliding guide pair.

[0022] The lower surface of the lifting part 1 is provided with two sets of opposing clamping mechanisms. Each set of clamping mechanisms includes at least one transverse drive mechanism 2 and one sliding seat 3. In this embodiment, each set of clamping mechanisms specifically includes two transverse drive mechanisms 2 and two sliding seats 3. The two sliding seats 3 of the same set are arranged laterally at intervals and fixed on a mounting base 12. The mounting base forms a sliding guide pair with the slide rail 13 fixed on the lower surface of the lifting part 1 through the slider provided on its upper part. The mounting base is fixedly connected to the piston rod end of the transverse drive mechanism 2, so that the sliding seat 3 can move stably along the line connecting the two sets of clamping mechanisms under the drive of the transverse drive mechanism 2. The transverse drive mechanism 2 can be a linear drive element such as a hydraulic cylinder or an electric push rod. Each sliding seat 3 has a clamping part 4 fixedly provided on its side wall, which extends horizontally towards the other clamping mechanism. The clamping part 4 is a plate-shaped or block-shaped structure, and its shape is adapted to the groove 5 pre-processed on the side wall of the mold. The opening direction of the groove 5 is facing and towards its corresponding clamping mechanism.

[0023] The specific working process is as follows: When it is necessary to pick up or put down the mold, the vertical drive mechanism 6 operates, driving the lifting part 1 to descend, so that all the clamping parts 4 move to the same height as the groove 5 on the side wall of the mold. The initial position of the mold can be determined manually or by existing limiting structures such as blocking cylinders to ensure that the clamping parts 4 are aligned with the groove 5. Subsequently, the horizontal drive mechanisms 2 of the two sets of clamping mechanisms operate synchronously, driving their respective sliding seats 3 and clamping parts 4 to move towards each other. The outer diameter of the clamping part 4 is smaller than the inner diameter of the groove 5, so that the clamping part 4 is inserted horizontally into the groove 5 of the mold, thereby realizing the gripping and clamping of the mold. Then, the lifting part 1 rises, and the mold can be transferred to the target station. When releasing the mold, the process is reversed: after the lifting part 1 descends and is in place, the horizontal drive mechanism 2 drives the sliding seat 3 to move in the opposite direction, so that the clamping parts 4 are withdrawn from the groove 5, and the mold is released.

[0024] Example 2, as Figures 6 to 9 As shown, the other structures and working processes of this embodiment are the same as in Embodiment 1. However, in this embodiment, the two ends of the side wall facing the mold of the clamping part 4 are respectively hinged by pins or the like to positioning parts 8 that can automatically reset. The positioning parts 8 preferably achieve automatic reset by torsion springs or other reset elements. Under normal conditions without external force, the positioning parts 8 and the clamping part 4 form an obtuse angle on the side facing the mold, and the end of the positioning part 8 extends towards the mold and protrudes from the end of the clamping part 4 facing the mold. At this time, the distance between the ends of the two positioning parts 8 is less than the inner diameter length of the groove 5.

[0025] The clamping part 4 has mounting grooves 9 at both ends of its sidewall facing the mold for mounting the positioning part; the outer end face of the mounting groove 9 and its side facing the mold are open. The groove wall of the mounting groove 9 constitutes a mechanical limit on the opening angle of the positioning part 8.

[0026] In actual operation, in the initial state, when the transverse drive mechanism 2 drives the clamping part 4, causing it to move along... Figure 6 When the part moves into the mold groove 5 in the direction of the dashed arrow, the end of the positioning part 8 extending in front will contact the inner end face of the groove 5 before the clamping part 4. Under the continuous feeding force, the positioning part 8 is squeezed by the inner end face of the groove 5 and moves along... Figure 6 The solid arrow indicates rotation, causing it to open outwards and compress or twist its reset element. During rotation, the outer end faces of the two positioning parts 8 abut against the inner sidewall of the groove 5, thereby fine-tuning and locking the mold's position in the lateral direction. The fine-tuning method is as follows: Figures 8 to 9 As shown, Figure 8 and Figure 9 The dashed lines in the diagram indicate the standard placement position of the mold. Figure 8 The lateral position of the middle mold is biased to the right of the standard position. When the positioning part 8 opens, the end face of the positioning part 8 on the left side of the clamping part 4 will contact the end face of the groove 5 before the end face of the positioning part 8 on the right side, thereby pushing the mold to move to the left to achieve the purpose of fine adjustment of the mold position. Figure 9 The lateral position of the mold is biased to the left of the standard position. When the positioning part 8 opens, the end face of the positioning part 8 on the right side of the clamping part 4 will contact the end face of the groove 5 before the end face of the positioning part 8 on the left side, thereby pushing the mold to the right. After the clamping part 4 contacts the end face of the groove, the clamping of the mold is completed. If the mold needs to be released, the lateral drive mechanism 2 drives the clamping part 4 to retract, and the positioning part 8 automatically returns to the normal angle position under the elastic force of the reset element, preparing for the next pick-and-place operation.
