[0002] The die frame is the support of the mold. For example, the part that combines and fixes the various parts of the mold according to a certain rule and position on the die-casting machine and enables the mold to be installed on the die-casting machine for work is called the die frame. It consists of an ejection mechanism, a guide mechanism, a pre-reset mechanism, a die foot pad, and a seat plate.

[0003] For example, in the patent publication number CN213614037U titled "A mold frame that is easy to disassemble and assemble", four guide pillars are installed between the mold frame bottom plate and the mold frame top plate, guide sleeves are installed on the outer walls of the four guide pillars, threaded mounting ends are provided at the lower ends of the guide pillars, and limited cover plates are provided at the upper ends of the guide sleeves. Four threaded mounting holes are provided inside the mold frame bottom plate, and the four threaded mounting holes are integrally formed with the mold frame bottom plate. The guide pillars are fixedly installed with the threaded mounting ends at the lower ends and the threaded mounting holes on the mold frame bottom plate, a sealing cavity is provided at the upper ends of the threaded mounting holes, and the sealing cavity is integrally formed with the mold frame bottom plate, a clamping cover plate is provided at the upper ends of the threaded mounting ends, and the clamping cover plate is integrally formed with the guide pillars, and the clamping cover plate is located inside the sealing cavity.

[0004] Since the mold frame is generally composed of multiple plates, and each plate needs to be fixed to ensure the stability of the internal structure of the mold cavity, but in the prior art, the plates are generally connected through threaded holes. When the two plates are not precisely connected, the direct connection of the screw threaded holes will cause deviation. Therefore, the existing template disassembly and assembly process is relatively complicated, which increases labor costs. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the plates in the prior art are generally connected by threaded holes. When the two plates are not accurately connected, the screw threaded holes directly connect and cause deviation. Therefore, the existing template disassembly and assembly process is relatively complicated, which increases the labor cost. A template frame that is easy to disassemble and assemble is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mold frame that is easy to disassemble and assemble, comprising a bottom plate, a side frame and a template, a split plate is installed between the side frame and the template, the inner side wall of the side frame is threadedly connected with a threaded nail, the inner side wall of the template and the split plate is provided with a circular cavity, and the inner top wall of the circular cavity of the template is fixedly connected with a cross seat, the outer side wall of the cross seat is slidably connected with a support plate, the outer side wall of the support plate is fixedly connected with a pin, side pin holes are provided inside the template and the split plate, the bottom surface of the cross seat is fixedly connected with a central axis, the outer side wall of the central axis is fixedly connected with a jacket, and a rotating rod is rotatably connected between the jacket and the support plate.

[0007] Preferably, one end of the threaded nail is fixedly connected to a ring seat, and the other end of the threaded nail is fixedly connected to a hexagonal nut.

[0008] Preferably, a spring is provided on the outer side wall of the central axis.

[0009] Preferably, one end of the spring is fixedly connected to the outer sleeve, and the other end of the spring is fixedly connected to a retaining ring.

[0010] Preferably, the inner side wall of the retaining ring is slidably connected to the outer side wall of the central shaft.

[0011] Preferably, one end of the ring seat overlaps the retaining ring.

[0012] Preferably, the outer side wall of the central axis is coated with lubricant.

[0013] Preferably, hexagonal grooves are provided at the four corners of the bottom surface of the bottom plate.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, by rotating the hexagonal nut, the top end of the threaded nail gradually approaches the retaining ring and squeezes it, so that the retaining ring drives the outer sleeve to move through the spring, and pushes the outer sleeve to the top cross seat position, thereby allowing the four support plates to be spread outward, and a pin is inserted into the side pin hole, and the mold frame is fixed as a whole by using the support plate and the pin. When the mold frame needs to be disassembled, the threaded nail is rotated in the opposite direction, and the outer sleeve can fall due to its own gravity, so that the pin is detached from the side pin hole, thereby realizing the effect of rapid disassembly of the mold frame.

[0016] 2. In the utility model, a retaining ring and a spring are provided at the bottom end of the central axis, and the outer jacket is supported by the retaining ring and the spring to prevent the outer jacket from being separated from the central axis. The downward elastic force of the spring when compressed is utilized to facilitate unscrewing the threaded nail from the side frame, thereby achieving a labor-saving effect during disassembly and assembly.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1-4 As shown, the utility model provides a mold frame which is easy to disassemble and assemble, including a bottom plate 1, a side frame 2 and a template 3, a dividing plate 4 is installed between the side frame 2 and the template 3, the inner side wall of the side frame 2 is threadedly connected with a threaded nail 8, the inner side wall of the template 3 and the dividing plate 4 is provided with a circular cavity, and the inner top wall of the circular cavity of the template 3 is fixedly connected with a cross seat 14, the outer side wall of the cross seat 14 is slidably connected with a support plate 11, the outer side wall of the support plate 11 is fixedly connected with a pin 13, side pin holes 5 are provided inside the template 3 and the dividing plate 4, the bottom surface of the cross seat 14 is fixedly connected with a central axis 6, the outer side wall of the central axis 6 is fixedly connected with a sleeve 7, and a rotating rod 12 is rotatably connected between the sleeve 7 and the support plate 11.

[0026] The following is a detailed description of the specific settings and functions of this embodiment. The mold installation cavity can be divided into an upper mold and a lower mold. The part where the upper mold and the lower mold contact each other is a template 3. A mold cavity is set inside the template 3, and the outside of the mold cavity is a mold frame. The mold frame is the skeleton of the outer layer of the mold cavity, wherein the side frame 2 is used to connect the template 3 and the bottom plate 1 to each other, generally playing a buffering role, and the split plate 4 has demoulding, cooling and other functions. When injecting materials, the template 3 and the split plate 4 need to be connected together. For quick disassembly and assembly, corresponding circular cavities are set at the four corners of the bottom plate 1, the side frame 2, the template 3 and the split plate 4, wherein a pin is set for fixing. The pin is divided into two parts, one of which is for fixing the cross seat 14 and the central axis 6 in the template 3, and the other is a threaded screw 8 that is inserted through. In the initial state, the ring seat 9 does not contact the retaining ring 16, and the four support plates 11 connected by the rotating rod 12 are all retracted to the innermost side. When it is necessary to start assembling the mold frame, the threaded nail 8 is installed on the threaded hole of the side frame 2, and then the hexagonal nut 10 is continuously rotated. The top of the threaded nail 8 gradually approaches the retaining ring 16 and squeezes the retaining ring 16, so that the retaining ring 16 drives the outer sleeve 7 to move through the spring 15, and pushes the outer sleeve 7 to the top of the cross seat 14, so that the four support plates 11 are spread outward, and a pin 13 is inserted into the side pin hole 5. The mold frame is fixed as a whole by the support plate 11 and the pin 13. When it is necessary to disassemble the mold frame, the threaded nail 8 is rotated in the opposite direction, and the outer sleeve 7 can fall due to its own gravity, so that the pin 13 is detached from the side pin hole 5, thereby realizing the effect of rapid disassembly of the mold frame.

[0027] Embodiment 2

[0028] like Figure 2 and Figure 4 As shown, one end of the threaded nail 8 is fixedly connected to the ring seat 9, and the other end of the threaded nail 8 is fixedly connected to the hexagonal nut 10. A spring 15 is provided on the outer wall of the central axis 6. One end of the spring 15 is fixedly connected to the outer sleeve 7, and the other end of the spring 15 is fixedly connected to the retaining ring 16. The inner wall of the retaining ring 16 is slidably connected to the outer wall of the central axis 6. One end of the ring seat 9 overlaps the retaining ring 16. The outer wall of the central axis 6 is coated with lubricant. Hexagonal grooves are provided at the four corners of the bottom surface of the base plate 1.

[0029] The effect achieved by the entire embodiment is that the spring 15 is installed between the outer sleeve 7 and the retaining ring 16. In the initial state, the spring 15 is in a naturally stretched state, the rotating rod 12 is fitted in the axial direction of the central axis 6, and the retaining ring 16 and the spring 15 are used to support the outer sleeve 7 to prevent the outer sleeve 7 from detaching from the central axis 6, thereby ensuring the stability of the overall structure. At the same time, the downward elastic force of the spring 15 when compressed is used to facilitate the screwing of the threaded nail 8 from the side frame 2, thereby achieving a labor-saving effect during disassembly and assembly.

[0030] The use method and working principle of the device: When splicing the mold frame, install the threaded nail 8 on the threaded hole of the side frame 2, and then continue to rotate the hexagonal nut 10, so that the top of the threaded nail 8 gradually approaches the retaining ring 16 and squeezes the retaining ring 16, so that the retaining ring 16 drives the outer sleeve 7 to move through the spring 15, and pushes the outer sleeve 7 to the top cross seat 14 position, so that the four support plates 11 are spread outward, and a pin 13 is inserted into the side pin hole 5, and the mold frame is fixed as a whole by using the support plate 11 and the pin 13, and the outer sleeve 7 is supported by the retaining ring 16 and the spring 15 to prevent the outer sleeve 7 from being separated from the central axis 6;

[0031] When disassembling the mold frame, the threaded nail 8 is rotated in the opposite direction, so that the outer sleeve 7 can fall due to its own gravity, so that the pin 13 is separated from the side pin hole 5. The downward elastic force of the spring 15 when compressed can facilitate the threaded nail 8 to be unscrewed from the side frame 2, thereby completing the disassembly and assembly of the mold frame.
