Abstract
Description
Technical Field

[0002] Injection molding is a widely used manufacturing process that can quickly mass-produce parts with complex shapes. Injection molds are tools used for injection molding. They are the core equipment for producing plastic parts. The injection molding process involves heating the plastic raw material to a fluid state, then injecting it into the mold and cooling it to form.
[0003] During the injection molding process, in order to speed up the cooling and molding of the molten plastic, a circulation pipe is generally set in the lower mold, and cooling water is introduced into the pipe to cool the raw materials to achieve the purpose of rapid molding. Due to water quality problems, sediments, rust or dirt may accumulate in the cooling channel. These accumulations will cause channel blockage over time. Secondly, poor sealing at the pipe joints may cause leakage in the cooling channel. When the above problems occur, the staff is required to suspend production for maintenance. Only after the maintenance is completed can the injection molding operation be carried out again. This not only increases maintenance costs, but also leads to long-term interruptions in production and reduces production efficiency. Frequent maintenance and long-term production downtime have a negative impact on the economic benefits of the enterprise.

[0025] Reference Figure 1-6A rapid prototyping injection mold comprises a top plate 1, a bottom plate 2 and four support columns 3, the two ends of the support columns 3 are respectively fixed to the lower surface of the top plate 1 and the upper surface of the bottom plate 2, the lower surface of the top plate 1 is fixedly connected with a fixed mold 4, a movable mold 5 is arranged below the fixed mold 4, the support columns 3 penetrate the surface of the movable mold 5, and the support columns 3 are slidably connected to the movable mold 5, a cooling groove 6 is arranged at the bottom of the movable mold 5, two cooling boxes 7 are arranged below the movable mold 5, the cooling boxes 7 are adapted to the cooling groove 6, a replacement component is arranged on the two cooling boxes 7, and a connecting component for connecting with the cooling box 7 is arranged on the movable mold 5.
[0026] Reference Figure 3 and Figure 5 The replacement assembly includes a fixed frame 9 and a mounting plate 8. The support column 3 passes through the surface of the fixed frame 9, and the support column 3 is slidably connected to the fixed frame 9. The mounting plate 8 is rotatably connected to the inner side of the fixed frame 9. The upper and lower surfaces of the mounting plate 8 are provided with placement grooves 20. The bottoms of the two cooling boxes 7 are respectively located inside the two placement grooves 20, and the two cooling boxes 7 are symmetrically arranged. Two fixing parts are arranged in the placement grooves 20, and the two fixing parts are used to fix the cooling box 7 on the mounting plate 8. By setting two cooling boxes 7, when the cooling box 7 in the working state fails, the mounting plate 8 is rotated to make the spare cooling box 7 contact with the movable mold 5. In this way, there is no need to wait for the complete repair to be completed before performing the injection molding operation, especially under frequent maintenance conditions, which improves the overall efficiency of the injection molding operation and ensures the economic benefits to the enterprise.
[0027] Reference Figure 5 and Figure 6 The fixing part includes a control cavity 12 embedded in the cooling box 7, a slider 14 is slidably connected to the inside of the control cavity 12, a spring 13 is provided between the side wall of the slider 14 and the inner side of the control cavity 12, a clamping block 16 is fixedly connected to the side wall of the slider 14, a clamping groove 15 is provided on the inner side of the placement groove 20, the end of the clamping block 16 away from the slider 14 extends to the inside of the clamping groove 15, the size of the clamping block 16 and the clamping groove 15 are adapted, and a push-pull handle 17 is fixedly connected to the side wall of the slider 14, and the push-pull handle 17 extends to the outside of the cooling box 7 away from the slider 14. Under the action of the clamping block 16 and the clamping groove 15, the cooling box 7 can be quickly fixed to the mounting plate 8, which can improve the efficiency of repair and maintenance.
[0028] Reference Figure 1 , Figure 2 and Figure 3The connecting assembly includes two openings 10 arranged on the movable mold 5, and the openings 10 are connected to the cooling groove 6. Two fixed plates 11 are rotatably connected to the cooling box 7. The two fixed plates 11 are respectively arranged opposite to the two openings 10. The fixed plates 11 are adapted to the sizes of the openings 10. When the fixed plates 11 are rotated so that the shapes of the fixed plates 11 and the openings 10 correspond, the fixed plates 11 can pass through the openings 10, and the cooling box 7 can be moved down and separated from the movable mold 5. In this way, the cooling box 7 can be quickly replaced, which improves the efficiency of the injection molding operation, and the cooling box 7 can be separated from the movable mold 5, without the need for the staff to disassemble the entire movable mold 5, thereby ensuring the precise correspondence between the movable mold 5 and the fixed mold 4, and facilitating the maintenance operation of the staff.
[0029] Reference Figure 1 and Figure 2 Four airbags 18 are fixedly connected to the bottom of the fixed frame 9. The airbags 18 are sleeved on the support column 3. One end of the airbag 18 away from the fixed frame 9 is fixed to the upper surface of the bottom plate 2. The airbag 18 can buffer the downward movement of the cooling box 7, preventing the cooling box 7 from directly colliding with the bottom plate 2 to cause damage to the equipment, and also preventing such collision from causing safety hazards to the staff.

[0031] The specific working principle of the utility model is as follows:
[0032] When a fault occurs in the cooling box 7 in the working state and needs to be repaired, the staff rotates the two fixing plates 11 so that the fixing plates 11 correspond to the shape of the opening 10, and then under the action of the gravity of the cooling box 7, the cooling box 7, the mounting plate 8 and the fixing frame 9 will move downward. At this time, the cooling part of the device is separated from the movable mold 5, and then the screwing handle 19 is turned to make the two cooling boxes 7 flip over, the faulty cooling box 7 faces downward, and the spare cooling box 7 faces upward, and then the fixing frame 9 is moved upward so that the spare cooling box 7 can be inserted into the cooling groove 6, and the fixing plate 11 on the spare cooling box 7 can pass through the opening 10, and then the fixing plate 11 is rotated to make it The shape of the opening 10 is in a cross state, so that the entire spare cooling box 7 can be fixed on the movable mold 5. Since the cooling box 7 and the movable mold 5 are detachable, it is convenient for the staff to carry out maintenance without disassembling the entire movable mold 5. On the other hand, the cooling box 7 can be quickly replaced, which shortens the downtime and improves the efficiency of the injection molding operation. It is worth mentioning that an air bag 18 is provided at the bottom of the fixing frame 9. When the cooling box 7 moves downward after being separated from the movable mold 5, the air bag 18 can buffer the downward movement of the cooling box 7, preventing the cooling box 7 from directly colliding with the bottom plate 2 to cause damage to the equipment, and also preventing safety hazards to the staff;
[0033] Furthermore, the staff presses the two push-pull handles 17 to move the slider 14 and the block 16, and then the block 16 disengages from the slot 15, so that the cooling box 7 and the mounting plate 8 can be separated. In this way, the faulty cooling box 7 can be disassembled for maintenance, and the staff does not need to stop the machine for maintenance and then continue to work. This reduces the maintenance cost and improves production efficiency.
