[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-5This utility model provides a technical solution: a mold frame for easy mold replacement, including an upper mold base 100 and a lower mold base 200 for mold installation and arranged in an upper and lower stacked manner. The lower mold base 200 includes a base plate 210 and a B plate 220. The B plate 220 is mounted parallel to the base plate 210 via two foot molds 230. Four guide pillars 240 arranged in a rectangular array are vertically installed on the B plate 220. The upper mold base 100 includes a top plate 110 and an A plate 12 fixedly installed on its bottom surface. 0. Four guide sleeves 130 are installed through the A plate 120 for the guide pillars 240 to fit through. The bottom surface of the A plate 120 and the top surface of the B plate 220 are both provided with recessed grooves for mold parting. The A plate 120 and the B plate 220 are both equipped with quick-release mechanisms 300 for easy mold parting and disassembly. The back of both molds is provided with actuating accessories 400 for positioning and ejection. The quick-release mechanism 300 includes a pad block 310 fixedly installed in the recessed groove for mold parting support and two symmetrically distributed... The system includes sliders 320 located on both sides of the pad 310, and two screws 330 for each slider 320. The two screws 330 are threaded through the two sliders 320 and rotatably connected to the pad 310. It also includes two fixed plates 340 fixedly connected to the side walls of plate A 120 or plate B 220, allowing the outer ends of the screws 330 to rotate. Handwheels 3310 are fixedly mounted on the outer ends of the screws 330. A first slope is provided on the outer surface of the inner side of each slider 320. The outer sides of the two sliders 320 are provided with locking blocks 3220. The action accessory 400 includes a limiting seat 410 located in the middle of the back of the mold parting and two symmetrically distributed slots 420 located on both sides of the limiting seat 410. The two sides of the limiting seat 410 are provided with two symmetrically distributed second slopes 4110. The two second slopes 4110 are parallel to the two first slopes 3210 respectively. The two slots 420 are respectively engaged and adapted to the two locking blocks 3220.

[0037] Based on the above structural design, this mold frame for easy mold replacement consists of an upper mold base 100 and a lower mold base 200. Both the A plate 120 of the upper mold base 100 and the B plate 220 of the lower mold base 200 are equipped with quick-release mechanisms 300 for mold parting, positioning, and ejection. The back of both molds is equipped with a matching actuating accessory 400 for the quick-release mechanism 300. Specifically, during operation, since the quick-release mechanisms 300 in the A plate 120 and the B plate 220 operate on the same principle, such as... Figure 3As shown, taking the quick-release mechanism 300 inside plate B 220 as an example, the quick-release mechanism 300 has two working states. When the mold is embedded in plate B 220, the operator can turn the two handwheels 3310 respectively, and with the help of the two screws 330, drive the two sliders 320 to move outward until the locking blocks 3220 on the outside of the two sliders 320 are respectively locked in the two slots 420. At this time, the two sliders 320 position the mold embedded in the recessed groove, and the quick-release mechanism 300 is in a fixed state. When the mold needs to be replaced, the operator can turn the two handwheels 3310 in the opposite direction, and with the help of the two screws 330, drive the two sliders 320 to move inward until the first slope surface 3210 on the inside of the two sliders 320 is in contact with the two second slope surfaces 4110 respectively. At this time, the outer sides of the two sliders 320 are locked inward. The locking blocks 3220 disengage from the two locking slots 420 respectively, and the mold parting mechanism is installed in the recessed groove. The operator continues to turn the two handwheels 3310, and the two sliders 320 continue to move closer to each other. With the help of the first slope 3210 and the second slope 4110 that are in contact with each other, the mold parting mechanism can be pushed out of the recessed groove. The quick release mechanism 300 is in the ejection state. This mold frame that facilitates mold replacement, by assembling the quick release mechanism 300 in the recessed groove of the A plate 120 or the B plate 220, and cooperating with the action accessory 400, replaces the traditional fastener connection with the external support locking method, which can realize the convenient assembly and disassembly of the mold in the mold frame. The operation is convenient. At the same time, with the help of the parallel first slope 3210 and the second slope 4110, it is easier to push out of the recessed groove when the mold parting mechanism is disassembled, which further increases the convenience of disassembly.

[0038] Furthermore, both sides of the outer surface of the pad 310 are provided with chamfered surfaces 3110, and the interior of the limiting seat 410 is provided with positioning grooves 4120 for the outer surface of the pad 310 to be adapted and accommodated.

[0039] Furthermore, it also includes a substrate 430 for integrally connecting the limiting seat 410 and the two card slots 420, the substrate 430 being attached to the back of the parting mold.

[0040] Furthermore, it also includes a positioning block 3410 located inside the fixing plate 340 and extending into the A plate 120 or the B plate 220, the positioning block 3410 being integrally connected to the fixing plate 340.

[0041] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
