Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, and in particular to a quick-assembly mold frame. Background Technology

[0002] The mold frame is a basic framework of the mold composed of metal parts such as templates, guide pillars, and guide sleeves. As the installation carrier of the core forming components of the mold, it provides structural support, precise positioning guidance, and motion coordination, ensuring that the mold works stably during the forming process and is compatible with the forming equipment. The purpose of assembling the mold frame is to enable the dispersed parts to work together and achieve precise fit, while verifying the rationality of the structure and adapting to the core components, so as to avoid mold failure due to part errors or fit problems.

[0003] The existing mold frame first precisely aligns each template with the guide pillars and positioning pins through positioning holes and pin holes on the template itself, ensuring accurate relative positions of the upper and lower templates. Then, bolts and screws are used to fasten the templates to the guide pillars, guide sleeves, and other components. In scenarios involving frequent assembly and disassembly, the drawbacks of bolt fixing in the existing mold frame structure are particularly prominent, resulting in low operational efficiency. Each disassembly requires loosening each bolt individually, and during assembly, the bolt holes must be realigned and tightened one by one. For mold frames with multiple bolt fixations, this consumes a significant amount of time and severely impacts the rhythm of mold replacement and maintenance.

[0004] Therefore, those skilled in the art have provided a quick-assembly mold to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-assembly mold frame that easily enables the fixing and disassembly of the upper and lower mold frames.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-assembly mold frame includes an upper mold frame, with a No. 1 support rod fixedly installed at the four corners of the lower end of the upper mold frame. Each of the four No. 1 support rods has a fixing device movably installed at its outer end. A lower mold frame is fixedly installed at the lower end of the four fixing devices. A slot is opened at the upper part of the outer end of each of the four No. 1 support rods.

[0008] The fixing device includes a base, with a first groove on both sides of the upper edge of the base. An arc-shaped baffle is fixedly installed on both sides of the upper edge of the base near the inner edge. A housing is rotatably installed on the upper end of the base. A second support rod is fixedly installed on both sides of the bottom end of the housing. The outer ends of the two second support rods are rotatably fitted with buckles. A spring is fixedly installed on the opposite end of the two buckles. A second groove is opened on both sides of the lower edge of the housing. A slide bar is slidably installed on the inner end of the two second grooves. A toggle plate is fixedly installed on the opposite end of the two slide bars.

[0009] Furthermore, the four outer shells are rotatably disposed at the outer ends of every two arc-shaped baffles, and the eight buckles are movably disposed at the inner ends of the four slots respectively.

[0010] Furthermore, the four bases are fixedly installed at the four corners of the upper end of the lower mold frame, and the opposite ends of each pair of springs are fixedly installed on both sides of the inner wall of the outer shell.

[0011] Furthermore, the eight latches are respectively movably disposed between every two arc-shaped baffles.

[0012] Furthermore, the eight toggle plates are movably disposed at the four outer ends of the housing and the four outer ends of the base.

[0013] Furthermore, the eight sliders are slidably disposed at the inner ends of the eight first-order slide grooves.

[0014] This utility model has the following beneficial effects:

[0015] This invention proposes a quick-assembly mold frame. The fixing of the upper and lower mold frames can be easily accomplished using four No. 1 support rods and four fixing devices, making the entire process convenient and efficient. When disassembly is required, simply rotate the inner shell of the fixing device 90 degrees counterclockwise. The latches will automatically retract, and then slide the side actuating plates downwards into the lower No. 1 groove. At this point, the No. 1 support rod can move freely inside the fixing device. During assembly, first insert the No. 1 support rod into the fixing device, then slide the side actuating plates upwards. Afterwards, whether rotating the outer shell 90 degrees clockwise or counterclockwise, the latches will precisely engage in the grooves, thus achieving a stable fixation of the upper and lower mold frames. The operation is smooth, the process convenient and efficient, greatly saving assembly time. Attached Figure Description

[0025] 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.

[0026] A quick-assembly mold frame includes an upper mold frame 1. A first support rod 2 is fixedly installed at the four corners of the lower end of the upper mold frame 1. A fixing device 3 is movably installed at the outer end of each of the four first support rods 2. A lower mold frame 4 is fixedly installed at the lower end of the four fixing devices 3. A slot 5 is opened at the upper part of the outer end of each of the four first support rods 2.

[0027] Specifically, the upper mold frame 1 serves as the upper main body of the mold frame, with a support rod 2 fixed at the four corners of its lower end. A slot 5 is provided at the upper outer end of the rod to cooperate with the fixing device 3 and provide an installation base for the upper part of the mold. The lower mold frame 4 serves as the lower main body, with a base 301 of the fixing device 3 fixed at the four corners of its upper end to provide an installation base for the lower part of the mold. The two are quickly connected and positioned through the fixing device 3 to form a stable mold frame system and ensure the stability of the mold during operation.

[0028] Reference Figures 3 to 7The fixing device 3 includes a base 301. A first groove 302 is opened on both sides of the upper edge of the base 301. An arc-shaped baffle 303 is fixedly installed on both sides of the upper edge of the base 301 near the inner edge. A housing 304 is rotatably installed on the upper end of the base 301. A second support rod 305 is fixedly installed on both sides of the bottom end of the housing 304. The outer ends of the two second support rods 305 are rotatably fitted with buckles 306. A spring 307 is fixedly installed on the opposite end of the two buckles 306. A second groove 308 is opened on both sides of the lower edge of the housing 304. A slide bar 309 is slidably installed on the inner end of the two second grooves 308. A toggle plate 310 is fixedly installed on the opposite end of the two slide bars 309.

[0029] Specifically, the arc-shaped baffle 303 is arc-shaped overall, with both ends also featuring an arc design, its curvature perfectly fitting the buckle 306. When the outer casing 304 is rotated, the second support rod 305 will cause the buckle 306 to rotate accordingly. At this time, the buckle 306 will retract towards the inner end of the outer casing 304, conforming to the arc shape on one side of the arc-shaped baffle 303. The end of the buckle 306 away from the second support rod 305 has a smooth arc surface. The main function of the slider 309 and the actuating plate 310 is to allow the slider 309 to enter the first sliding groove 302 when the buckle 306 retracts, thereby restricting the rotation of the outer casing 304. Since the buckle 306 is connected to the inner wall of the outer shell 304 by the spring 307, and the end of the buckle 306 away from the second support rod 305 is curved and relatively smooth, the spring 307 will be squeezed when the buckle 306 is retracted. At this time, the buckle 306 is in contact with the outer end of the arc-shaped baffle 303, and it is very easy to slide under the force of the spring 307. Therefore, it is necessary to add a structure that can fix the outer shell 304.

[0030] Reference Figures 1 to 7 Four outer shells 304 are rotatably mounted on the outer ends of every two arc-shaped baffles 303, eight buckles 306 are movably mounted on the inner ends of four slots 5, four bases 301 are fixedly mounted on the four corners of the upper end of the lower mold frame 4, two springs 307 are fixedly mounted on the inner walls of the outer shells 304 at opposite ends, eight buckles 306 are movably mounted between every two arc-shaped baffles 303, eight toggle plates 310 are movably mounted on the outer ends of the four outer shells 304 and the four bases 301, and eight slide bars 309 are slidably mounted on the inner ends of eight first slide grooves 302;

[0031] Specifically, the inner height of the slot 5 is consistent with the inner height of the outer shell 304, which is just enough to accommodate the height of the buckle 306. Furthermore, when the first support rod 2 is fully inserted into the fixing device 3, the height of the slot 5 remains level with the inner height of the outer shell 304. This design effectively prevents gaps between the upper mold frame 1 and the lower mold frame 4 due to loose fit between the buckle 306 and the slot 5, thus ensuring the tightness and stability of the overall mold frame connection. The size of the first slide groove 302 is just enough to accommodate the slide bar 309, allowing the slide bar 309 to slide smoothly at its inner end. When the upper mold frame 1 and the lower mold frame 4 are installed, the line connecting the two points of the two first slide grooves 302 of each fixing device 3 is perpendicular to the line connecting the two points of the two second slide grooves 308.

[0032] Working principle: During installation, first operate one of the fixing devices 3: rotate the outer shell 304 counterclockwise to 90 degrees. At this time, the two second support rods 305 inside the outer shell 304 will drive the outer end buckle 306 to enter between the arc-shaped baffle 303 and the outer shell 304 along the edge of one end of the arc-shaped baffle 303, while compressing the spring 307. At this time, the two first slide grooves 302 and the two second slide grooves 308 are aligned in the horizontal and vertical directions. Move the two actuating plates 310 on both sides to make the two slide bars 309 enter the inner end of the two first slide grooves 302, thereby fixing the outer shell 304 to ensure its stability. Repeat the above operation for the other fixing devices 3 to complete the retraction operation of the buckle 306. Subsequently, align the four No. 1 support rods 2 of the upper mold frame 1 with the four fixing devices 3 and insert them to the bottom. Then operate one of the fixing devices 3: move the two side actuating plates 310 to retract the two slide bars 309 into the No. 2 slide groove 308. Then rotate the outer shell 304 clockwise or counterclockwise by 90 degrees. At this time, the two No. 2 support rods 305 inside the outer shell 304 will drive the inner end buckles 306 to move between the two arc-shaped baffles 303. The two springs 307 will push the two buckles 306 into the inner end of the slot 5. Repeat the above operation for the other fixing devices 3 to complete the fixing. When disassembling, simply repeat the operation of retracting the buckles 306 to separate the upper mold frame 1 from the lower mold frame 4. The whole operation process is convenient and efficient, greatly saving assembly time.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
