[0001] This application relates to the field of mold changing technology, and more specifically, to a quick changing and positioning device. Background Technology

[0002] Currently, in order to enrich their product offerings, manufacturers often develop products of the same type but different sizes. For example, they may develop multiple models of the same type of aluminum tube based on length. While this enriches the product range, the cost of making individual molds is high, and changing molds can affect the production efficiency of the production line. Furthermore, for larger products, larger mold operation machines may be required to complete the production and processing, which will further increase costs.

[0003] Therefore, this application proposes a quick-change positioning device to solve the above-mentioned problems. Utility Model Content

[0011] Furthermore, the support strip is also detachably equipped with a clip, the bottom of which is attached to the telescopic block.

[0012] Through the above technical solution, the clamps further secure the telescopic blocks, preventing them from shifting due to unexpected situations during operation, thus ensuring the stability of the device and improving processing accuracy and product quality. Simultaneously, the detachable design of the clamps facilitates installation, disassembly, and maintenance, making it more convenient to inspect or replace the telescopic blocks.

[0013] Furthermore, the mold base is provided with an ejection mechanism at the bottom of the B plate, the ejection mechanism is provided with a support bar, the support bar is located directly below the support bar, the support bar is provided with a push rod vertically, and the slot is provided with a plurality of through holes that match the push rod.

[0014] Through the above technical solution, the ejection mechanism, support bar, and ejector rod configuration allows for quick and convenient workpiece removal by ejecting the workpiece through the through-hole in the support slot when it needs to be removed, thus improving production efficiency. Furthermore, the design of the ejection mechanism located at the bottom of the mold base and B-plate makes efficient use of space and will not interfere with the normal operation of other components.

[0015] Furthermore, the support strip is also detachably provided with a support block, and there are two connection points between the support block and the support strip. The bottom of the top rod is connected to the support block and located between the two connection points.

[0016] Through the above technical solution, the support block set on the support bar provides a stable support point for the push rod, making the push rod more stable when ejecting the workpiece, ensuring a smooth ejection process, and further guaranteeing the quality and efficiency of workpiece removal; on the other hand, the design of the two connection points between the support block and the support bar, as well as the layout of the push rod between the two connection points, makes the entire structure more uniformly stressed and improves the durability of the device.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] (1) The quick-change positioning device, through its design of telescopic blocks and ejection mechanisms, facilitates the positioning and removal of workpieces, reduces time loss during mold changes and processing, and improves the overall production efficiency of the production line. Moreover, when changing molds for products of different sizes, it can complete the preparation work more quickly, reducing the impact on production efficiency;

[0019] (2) This device can, to some extent, avoid the need for frequent development of new molds or replacement of large mold operating machines due to changes in product size. The device can adapt to workpieces of various sizes, reducing the need for individual mold opening, thereby reducing mold costs and cost increases caused by mold-related issues. At the same time, the detachable design of some components in the device facilitates maintenance and replacement, reducing maintenance costs and equipment upgrade costs. Attached Figure Description

[0027] Example:

[0028] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.

[0029] This application discloses a quick-change positioning device, including:

[0030] Mold base 1, molds are respectively set on mold base 1, molds include B plate 2, rear mold core 3 is set on B plate 2, and slider insert 4 is engaged on rear mold core 3;

[0031] The B plate 2 is provided with the same number of support strips 5 as the slider insert 4. The support strip 5 is a semi-open structure and is provided with the same groove 6 as the workpiece 12. The end of the support strip 5 away from the B plate 2 is located in the groove 6 and is detachably provided with a telescopic block 7.

[0032] The telescopic block includes a main body 8, a compression spring 9 is provided inside the main body 8, a movable rod 10 is slidably provided inside the main body 8, the movable rod 10 passes through the main body 8 and the compression spring 9, and a support block 11 is provided on the side of the movable rod 10 facing the slider insert 4, and the support block 11 abuts against the compression spring 9 on the side facing the compression spring 9.

[0033] Workpiece 12 is located in the groove 6 of the support strip 5, and the two ends of workpiece 12 abut against the slider insert 4 and the support block 11 respectively.

[0034] See Figure 1 , Figure 2 and Figure 3 The support strip 5 is also detachably equipped with a clip 13, the bottom of which is attached to the telescopic block 7. The clip 13 further secures the telescopic block 7, preventing it from shifting during operation due to unforeseen circumstances, thus ensuring the stability of the device during operation and improving processing accuracy and product quality. At the same time, the detachable design of the clip 13 facilitates installation, disassembly, and maintenance, making it more convenient to inspect or replace the telescopic block 7.

[0035] See Figure 1 , Figure 2 and Figure 3 The mold base 1, located at the bottom of plate B 2, is equipped with an ejection mechanism. A support bar 14 is mounted on the ejection mechanism, positioned directly below the support bar 5. A push rod 15 is vertically mounted on the support bar 14. The tray 6 has several through holes 16 that match the push rod 15. The arrangement of the ejection mechanism, support bar 14, and push rod 15 allows for quick and convenient removal of the workpiece 12 by pushing it out through the through holes 16 of the tray 6 via the push rod 15, thus improving production efficiency. Furthermore, the design of the ejection mechanism, located at the bottom of the mold base 1 and plate B, makes efficient use of space and does not interfere with the normal operation of other components.

[0036] See Figure 1 , Figure 2 and Figure 3The support bar 5 is also detachably equipped with a support block 17. The support block 17 and the support bar 14 have two connection points. The bottom of the push rod 15 is connected to the support block 17 and located between the two connection points. The support block 17 on the support bar 5 provides a stable support point for the push rod 15, making the push rod 15 more stable when ejecting the workpiece 12, ensuring a smooth ejection process, and further guaranteeing the quality and efficiency of removing the workpiece 12. On the other hand, the design of the two connection points between the support block 17 and the support bar 14, as well as the layout of the push rod 15 between the two connection points, makes the entire structure more evenly stressed and improves the durability of the device.

[0037] The implementation principle of a quick-change positioning device according to an embodiment of this application is as follows:

[0038] When it is necessary to install workpiece 12, place workpiece 12 in the groove 6 of the support strip 5, with both ends of workpiece 12 abutting against the slider insert 4 and the support block 11 of the telescopic block 7, respectively. The compression spring 9 in the telescopic block 7 provides outward elastic force to the movable rod 10, so that the support block 11 stably abuts against workpiece 12; a clip 13 can be set on the support strip 5 to further fix the telescopic block 7.

[0039] When workpiece 12 needs to be removed, the ejection mechanism at the bottom of plate B on mold base 1 operates. The ejector rod 15 on the support bar 14 of the ejection mechanism pushes workpiece 12 upward through the through hole 16 of the slot 6, thus removing workpiece 12. The support block 17 on the support bar 5 provides stable support for the ejector rod 15, ensuring a smooth ejection process. The entire process enables rapid positioning and replacement of workpiece 12 in the mold, improving production efficiency and adaptability.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
