Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an injection mold which is easy to clean. Background Art

[0002] At present, injection mold is a precision tool used to manufacture plastic products. It is usually made of metal materials such as steel or aluminum, designed with parts and cavities, used to inject molten plastic to form products of desired shapes. These molds are widely used in electronics, automobiles, medical, home furnishing and other industries, and are one of the important processing technologies in modern industry.

[0003] In the prior art, the authorization announcement number is CN218593526U, and the name is an injection mold that is easy to clean. The patent includes a lower mold, an injection cavity, a stepped through hole, a first drive shaft, a turntable, a spline shaft spline sleeve assembly, a spray hole, a connecting pipe, a corrugated rubber pipe, a water injection pipe, and a second and third drive shaft. The first drive shaft is driven to rotate by the turntable, and the second drive shaft is driven to rotate by the bevel gear pair to cooperate with the worm gear assembly to rotate the third drive shaft. This series of ingenious designs enables the third drive shaft to push the connecting pipe upward through the gear rack assembly. This process further promotes the upward movement of the tubular spline shaft of the spline shaft spline sleeve assembly until the spray hole accurately reaches the injection cavity. The water injection pipe is connected to the cleaning liquid holding device. By pressurizing, we can easily clean the injection cavity thoroughly, greatly shortening the cleaning time, thereby improving the overall production efficiency. This design is not only practical, but also greatly improves the maintenance convenience and service life of the injection mold.

[0004] However, this patent uses clean water to clean the mold. If the water cannot be wiped off in time after cleaning, it will affect the quality of subsequent injection molded products. The mold also has the risk of rust. In addition, this patent cannot adjust the balance and is not stable enough when used.

[0005] In the prior art, the authorization announcement number is CN211334344U, and the name is a plastic injection mold that is easy to clean up waste. The patent drives the screw to rotate through a motor, and the precise cooperation between the slide rod and the slide sleeve enables the screw sleeve to flexibly drive the bottom plate to move left and right, and easily separate the bottom plate from the lower mold. This design not only greatly facilitates the cleaning process, so that the water and waste after cleaning can flow smoothly into the collection box for centralized treatment, but also significantly improves the cleaning efficiency. The patent abandons the traditional manual cleaning method and adopts a combination of a motor, a screw, a lower mold, a bottom plate, an adjustment component and a spray gun to form a set of efficient and automated cleaning system. This method not only has a better cleaning effect, but also greatly reduces the intensity of manual labor and improves work efficiency. The patent also cleverly sets a collection box, a chute and a slider. The coordinated work of these components can effectively collect wastewater and waste generated during the cleaning process, prevent secondary pollution, and protect the environment.

[0006] However, this patent also uses clean water to clean the inside of the mold, and the water needs to be wiped dry after cleaning, which increases the workload. Utility Model Content

Through the arrangement of structures such as the rack plate 17 and the threaded sleeve 18, when the upper mold 4 and the lower mold 5 are separated, the rack plate 17 drives the gear 16 to rotate, the threaded sleeve 18 rotates accordingly and drives the linkage screw 15 to move, and the injection pipe 14 moves accordingly, and the air pump 12 is started, and the injection pipe 14 cleans the inside of the cavity.

[0032] See also Figure 2-4 The rack plate 17 is meshed with the gear 16, a rotation groove is provided inside the fixed block 19, and the threaded sleeve 18 is rotatably installed inside the rotation groove.

[0033] See also Figure 4 A transverse thread groove is provided inside the threaded sleeve 18, and the linkage screw 15 is threadedly connected inside the transverse thread groove.

[0034] See also Figure 5 A circular groove is provided inside the upper mold 4, and the guide rod 8 passes through the inside of the circular groove.

[0035] See also Figure 2-3 A plurality of symmetrically arranged sliding grooves are provided inside the lower mold 5, and a plurality of ejector rods 7 are slidably connected inside the plurality of sliding grooves respectively.

[0036] See also Figure 4 A through groove is provided inside the support block 20, and the air injection pipe 14 is slidably connected inside the through groove.

[0037] The specific implementation process of the utility model is as follows: when the upper mold 4 is separated from the lower mold 5, the rack plate 17 will drive the gear 16 to start rotating, and this action will further cause the threaded sleeve 18 to rotate, thereby driving the linkage screw 15 to move, and the jet pipe 14 moves with the movement of the linkage screw 15. When the jet pipe 14 reaches the specified position, the air pump 12 is started, and the jet pipe 14 will thoroughly clean the inside of the cavity.

Similarly, when the upper mold 4 and the lower mold 5 are closed, the outward movement of the jet pipe 14 will not affect the injection molding operation.

[0038] Example 2

[0039] See also Figure 1-5 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that four symmetrically arranged columns 9 are welded to the bottom of the base plate 1, and the inner parts of the four columns 9 are all threadedly installed with lifting screws 11, and the bottom of the lifting screws 11 is welded with an anti-sliding block 10. Through the arrangement of the lifting screws 11, the anti-sliding block 10 and other structures, according to the flatness of the ground where the base plate 1 is placed, the four lifting screws 11 are rotated respectively to adjust the distance between the anti-sliding block 10 and the base plate 1. When the base plate 1 is in a horizontal state, the lifting screws 11 are stopped from rotating, so that the base plate 1 can always remain horizontal and is more stable when used.

[0040] See also Figure 1-4 The four threaded sleeves 18 are provided with vertical thread grooves inside, and the four lifting screws 11 are respectively threadedly connected inside the four vertical thread grooves.

The specific steps are as follows: first, observe the flatness of the ground where the base plate 1 is placed. Then, by rotating the four lifting screws 11, flexibly adjust the distance between the anti-sliding plate 10 and the base plate 1. Once the base plate 1 remains horizontal, immediately stop rotating the lifting screws 11 to ensure that the base plate 1 is stable and balanced. This adjustment method can keep the base plate 1 level under different ground conditions, thereby ensuring stability during use.

[0042] In addition, the lower mold 5 is fixedly connected with a collecting net 3 by screws, and the broken materials blown out by the air jet pipe 14 will be collected by the collecting net 3, which is convenient for subsequent unified processing. There is no need to clean the surrounding ground additionally, which reduces the workload of the staff.
