Description

Technical Field

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

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. They mainly shape raw materials into specific shapes and sizes by applying pressure to the material.

[0003] During the use of the mold, it needs to be installed on the mold base, which requires the use of multiple bolts to fix the mold, thus increasing the time and complexity of disassembling and assembling the mold.

[0004] Therefore, in the process of installing the mold on the mold base, multiple bolts are needed to fix the mold, which increases the time and complexity of mold assembly and disassembly. A convenient mold assembly and disassembly structure can be designed so that the mold can be assembled and disassembled in one step through the automatic snap-locking of the elastic locking component. Utility Model Content

[0005] To overcome the situation where multiple bolts are needed to install the mold onto the mold base during the mold installation process, which increases the time and complexity of mold assembly and disassembly.

[0006] The technical solution of this utility model is as follows: a convenient mold assembly and disassembly structure, including two sets of locking blocks; and also including oblique insertion corners. Each set of locking blocks is provided with four locking blocks. A spring guide rod is installed on the outer side of each locking block. An upper oblique groove is opened at the upper end of each locking block, and an oblique slot is opened in the upper oblique groove. A lower oblique groove is opened at the lower end of each locking block. An insertion rod is provided between the four locking blocks in the same set. A buckle is fixedly connected to the upper end of each insertion rod. An oblique insertion corner is slidably connected in the oblique slot. The upper ends of the four oblique insertion corners in the same set are fixedly connected to four-sided lifting plates. A threaded rod is threaded in the middle of the four-sided lifting plates.

[0007] Preferably, the buckle is inserted into the lower inclined groove and pressed upward to force the four locking blocks in the same group to move away from each other, allowing the buckle to pass between the four locking blocks. After the locking block enters the upper inclined groove, the spring guide rod resets the locking block to lock the insert rod and buckle together, thereby installing the mold body at the lower end of the insert rod at the lower end of the mold base. When it is necessary to disassemble the mold body, the rotation of the threaded rod causes the four-sided lifting plate and the inclined insertion angle to descend together, allowing the inclined insertion angle to insert into the inclined slot. As the inclined insertion angle continues to descend, it pushes the locking block in the inclined slot to reopen the closed locking blocks. When the four-sided lifting plate descends to the lowest position, the lower end of the four-sided lifting plate is blocked by the upper end of the locking block, and the buckle has been disengaged from the upper inclined groove. Therefore, the mold body can be pulled out together with the insert rod and buckle.

[0008] Preferably, the buckle is set in the upper inclined groove and the buckle is located at the lower end of the threaded bar. The spring guide rod consists of a guide rod and a spring set on the outside of the guide rod.

[0009] Preferably, two threaded rods are provided, and each threaded rod has a driven spur gear fixed to its upper end, with a driving spur gear meshing between the two driven spur gears.

[0010] Preferably, a driven bevel gear is fixedly connected to the lower end of the driving spur gear, a driving bevel gear is meshed with the lower end of the driven bevel gear, and a rotating shaft is fixedly connected to the driving bevel gear.

[0011] Preferably, an upper mold base is provided on the outer side of the four-sided lifting plate, and two four-sided lifting grooves are opened at the lower end of the upper mold base, and the four-sided lifting grooves are slidably connected to the four-sided lifting plate.

[0012] Preferably, the lower end of the upper mold base is fixedly connected to the lower mold base, the lower mold base has eight sliding holes, the lower end of the lower mold base has an insertion hole, the lower end of the insertion rod is fixedly connected to the mold body, and the mold body is located at the lower end of the insertion hole.

[0013] Preferably, the sliding holes are all slidably connected to the guide rod of the spring guide rod, and the threaded rod, driven bevel gear and rotating shaft are all rotatably connected to the upper mold base, with the rotating shaft passing through the front and rear ends of the upper mold base.

[0014] The beneficial effects of this utility model are:

[0015] By setting the locking blocks and the angled insertion, the cap can be inserted into the lower inclined groove and pressed upwards to force the four locking blocks in the same group to move away from each other, allowing the cap to pass through the four locking blocks. After the locking blocks enter the upper inclined groove, the spring guide rod resets the locking blocks to lock the insertion rod and the cap together, thereby installing the mold body at the lower end of the insertion rod at the lower end of the mold base. When it is necessary to disassemble the mold body, the rotation of the threaded rod causes the four-sided lifting plates and the angled insertion to descend together, allowing the angled insertion to insert into the inclined slot. As the angled insertion continues to descend, it pushes the locking blocks in the inclined slot to reopen the closed locking blocks. When the four-sided lifting plates descend to the lowest position, the lower end of the four-sided lifting plates will be abutted by the upper end of the locking blocks, and the cap has disengaged from the upper inclined groove. Therefore, the mold body can be pulled out together with the insertion rod and the cap. Thus, the automatic locking of the elastic locking fastener allows for one-step mold disassembly and assembly, reducing the time and complexity of mold disassembly and assembly.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1-10This utility model provides an embodiment of a convenient mold assembly and disassembly structure, including two sets of locking blocks 1; and also including inclined insertion angles 8. Each set of locking blocks 1 is provided with four locking blocks 1. A spring guide rod 2 is installed on the outer side of each locking block 1. An upper inclined groove 3 is opened at the upper end of each locking block 1, and an inclined slot 4 is opened in the upper inclined groove 3. A lower inclined groove 5 is opened at the lower end of each locking block 1. An insertion rod 6 is provided between the four locking blocks 1 in the same set. A buckle 7 is fixedly connected to the upper end of each insertion rod 6. An inclined insertion angle 8 is slidably connected in the inclined slot 4. The upper ends of the four inclined insertion angles 8 in the same set are jointly fixedly connected to a four-sided lifting plate 9. A threaded rod 10 is threaded in the middle of the four-sided lifting plate 9. The buckle 7 is inserted into the lower inclined groove 5 and pressed upward to force the four locking blocks 1 in the same set to move away from each other, so that the buckle 7 can be removed from the lower inclined groove 5. The four locking blocks 1 pass through each other. After the locking blocks 1 enter the upper inclined groove 3, the spring guide rod 2 resets the locking blocks 1 so that the insert rod 6 and the buckle 7 are locked together by the locking blocks 1, thereby installing the mold body 21 at the lower end of the insert rod 6 at the lower end of the mold base. When it is necessary to disassemble the mold body 21, the rotation of the threaded rod 10 causes the four-sided lifting plate 9 and the inclined insertion angle 8 to descend together, so that the inclined insertion angle 8 can be inserted into the inclined slot 4. The inclined insertion angle 8 will push the locking blocks 1 in the inclined slot 4 during the descent, so as to reopen the closed locking blocks 1. When the four-sided lifting plate 9 descends to the lowest position, the lower end of the four-sided lifting plate 9 will be abutted by the upper end of the locking block 1, and the buckle 7 has been disengaged from the upper inclined groove 3. Therefore, the mold body 21 can be pulled out together with the insert rod 6 and the buckle 7.

[0029] Please see Figures 1-2 and Figures 4-6 In this embodiment, the buckle 7 is disposed in the upper inclined groove 3 and is located at the lower end of the threaded rod 10. The spring guide rod 2 is composed of a guide rod and a spring disposed on the outside of the guide rod. There are two threaded rods 10, and the upper end of each threaded rod 10 is fixedly connected to a driven spur gear 11. The two driven spur gears 11 are meshed together with a driving spur gear 12 in the middle. The lower end of the driving spur gear 12 is fixedly connected to a driven bevel gear 13. The lower end of the driven bevel gear 13 is meshed with a driving bevel gear 14. A rotating shaft 15 is fixedly connected to the driving bevel gear 14. Shaking the rotating shaft 15 can cause the driven bevel gear 13 to rotate through the driving bevel gear 14. The driven bevel gear 13 then causes the driven spur gears 11 on both sides to rotate together through the driving spur gear 12, so that the threaded rods 10 on both sides can rotate together through the driven spur gears 11 on both sides.

[0030] Please see Figures 5-10In this embodiment, an upper mold base 16 is provided on the outer side of the four-sided lifting plate 9. Two four-sided lifting grooves 17 are opened at the lower end of the upper mold base 16, and the four-sided lifting grooves 17 are slidably connected to the four-sided lifting plate 9. The four-sided lifting grooves 17 are used to allow the four-sided lifting plate 9 to only lift and not rotate. A lower mold base 18 is fixedly connected to the lower end of the upper mold base 16. Eight sliding holes 19 are opened on the lower mold base 18. An insertion hole 20 is opened at the lower end of the lower mold base 18. The mold body 21 is fixedly connected to the lower end of the insertion rod 6, and the mold body 21 is located at the lower end of the insertion hole 20. The sliding hole 19 is used for the guide rod of the spring guide rod 2 to slide for reciprocating motion. The insertion hole 20 is used to insert the insertion rod 6 and the buckle 7. The sliding holes 19 are all slidably connected to the guide rod of the spring guide rod 2. The threaded rod 10, the driven bevel gear 13 and the rotating shaft 15 are all rotatably connected to the upper mold base 16, and the rotating shaft 15 passes through the front and rear ends of the upper mold base 16.

[0031] When in use, insert the buckle 7 into the lower inclined groove 5 and press it upward to force the four locking blocks 1 in the same group to move away from each other, so that the buckle 7 passes through the four locking blocks 1. After the locking blocks 1 enter the upper inclined groove 3, the spring guide rod 2 resets the locking blocks 1 so that the plug rod 6 and the buckle 7 are locked together by the locking blocks 1, thereby installing the mold body 21 at the lower end of the plug rod 6 at the lower end of the mold base.

[0032] When it is necessary to disassemble the mold body 21, the rotating shaft 15 can drive the bevel gear 14 to rotate the driven bevel gear 13. The driven bevel gear 13 then drives the spur gear 12 to rotate the driven spur gears 11 on both sides together. The driven spur gears 11 on both sides then rotate the threaded rods 10 on both sides together. The rotation of the threaded rods 10 causes the four-sided lifting plate 9 and the inclined insertion angle 8 to descend together, so that the inclined insertion angle 8 can be inserted into the inclined slot 4. As the inclined insertion angle 8 continues to descend, it pushes the locking block 1 in the inclined slot 4 to reopen the closed locking block 1. When the four-sided lifting plate 9 descends to the lowest position, the lower end face of the four-sided lifting plate 9 will be abutted by the upper end face of the locking block 1, and the buckle 7 has been disengaged from the upper inclined groove 3. Therefore, the mold body 21 can be pulled out together with the insertion rod 6 and the buckle 7.

[0033] Through the above steps, by setting the locking block 1 and the inclined insertion angle 8, the buckle 7 can be inserted into the lower inclined groove 5 and pressed upward to force the four locking blocks 1 in the same group to move away from each other, allowing the buckle 7 to pass between the four locking blocks 1. After the locking block 1 enters the upper inclined groove 3, the spring guide rod 2 resets the locking block 1 so that the insertion rod 6 and the buckle 7 are locked together by the locking block 1, thereby installing the mold body 21 at the lower end of the insertion rod 6 at the lower end of the mold base. When it is necessary to disassemble the mold body 21, the rotation of the threaded rod 10 causes the four-sided lifting plate 9 and the inclined insertion angle 8 to descend together. The angled insertion angle 8 is inserted into the angled slot 4, and the angled insertion angle 8 will push the locking block 1 in the angled slot 4 during the continued descent, so as to reopen the closed locking block 1. When the four-sided lifting plate 9 descends to the lowest position, the lower end face of the four-sided lifting plate 9 will be blocked by the upper end face of the locking block 1, and the buckle 7 has been disengaged from the upper inclined groove 3. Therefore, the mold body 21 can be pulled out together with the insertion rod 6 and the buckle 7. Thus, the mold can be disassembled and assembled in one step through the automatic buckling of the elastic locking fastener, so as to reduce the time consumption and operation complexity of disassembling and assembling the mold.
