Description

Technical Field

[0001] The invention relates to a plastic packaging mould cleaning unit and a supporting frame thereof, belonging to the technical field of plastic packaging mould cleaning. Background Art

[0002] During the production and use of plastic encapsulation molds, various stains, residual glue and particulate impurities often accumulate on the mold surface. These pollutants not only damage the appearance quality of the mold, but may also have a serious negative impact on the subsequent plastic encapsulation process. At present, conventional cleaning equipment mainly uses low-pressure cleaning, and its cleaning effect is often unsatisfactory for stubborn stains and residual glue attached to the mold surface.

[0003] On the other hand, if you try to use high-pressure water for cleaning, although it can enhance the cleaning effect, the splashing of high-pressure water can easily pollute the surrounding environment, which is not conducive to the maintenance of the production environment. More importantly, after the cleaning is completed, the water stains remaining on the surface of the plastic mold will directly affect its subsequent use, and it often takes a long time to wait to ensure that the mold is completely dry, which undoubtedly reduces production efficiency.

[0004] Therefore, developing a cleaning device that can efficiently clean stains and residual glue on the mold surface while avoiding high-pressure water splashing and reducing water stain residue is of great significance for improving the production efficiency and use effect of plastic packaging molds. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a plastic packaging mold cleaning unit and a supporting frame thereof, which can solve the problems of poor cleaning effect and splashing of cleaning liquid during the cleaning process of the plastic packaging mold.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a plastic encapsulation mold cleaning unit, the cleaning unit forms a cleaning area M and at least one high-pressure flushing area N on the surface of the plastic encapsulation mold, the cleaning unit comprises: a first outlet, the first outlet can form the cleaning area M on the mold surface along its outlet direction; the second outlet can form the high-pressure flushing area N on the mold surface along its outlet direction; the outlet direction of the first outlet is perpendicular to the surface of the plastic encapsulation mold, and the angle between the outlet direction of the second outlet and the surface of the plastic encapsulation mold is an acute angle; the cleaning area M and the high-pressure flushing area N partially overlap; the first outlet and the second outlet can both discharge cleaning liquid.

[0007] Preferably, both the first outlet and the second outlet can blow air toward the surface of the plastic packaging mold.

[0008] Preferably, the cleaning unit can form a drying area m on the surface of the encapsulation mold, and the drying area m is formed on the mold surface along the outlet direction of the first outlet, and the drying area m and the cleaning area M overlap.

[0009] Preferably, the air outlet direction of the second outlet can be changed.

[0010] Preferably, the number of the second outlets is two, and they are respectively arranged on both sides of the first outlet.

[0011] Preferably, the two second outlets can form two high-pressure flushing areas N, and the two high-pressure flushing areas N overlap with two side portions of the cleaning area M respectively.

[0012] Preferably, the second outlet is flat in shape.

[0013] A bracket includes a cleaning unit and a slide rail, which is horizontally arranged above a plastic packaging mold, and the cleaning unit is slidably installed on the slide rail along the length direction of the slide rail; a fixed frame, the slide rail can slide on the fixed frame, and its sliding direction is perpendicular to the sliding direction of the cleaning unit.

[0014] Beneficial effects:

[0015] The second outlet of the present invention can spray out high-pressure flushing liquid with a relatively high flow rate. This high-pressure flushing liquid has a strong impact force and can effectively blow away the stains and residues firmly attached to the mold. The outlet direction of the second outlet has a certain angle with the surface of the plastic packaging mold. This design enables the high-pressure flushing liquid to act more accurately on the stubborn stains on the mold surface, thereby improving the cleaning effect.

[0016] The first outlet and the second outlet of the present invention not only have the function of discharging liquid, but also can eject gas. When the gas passes through the plastic sealing mold, the liquid remaining on the mold surface can be effectively blown away quickly, achieving the purpose of quickly cleaning water stains, thereby greatly improving the cleaning efficiency and ensuring that the mold surface is dry and clean.

DETAILED DESCRIPTION

[0025] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0026] Embodiment 1

[0027] like Figure 1-Figure 3 As shown, in this embodiment, a plastic sealing mold cleaning unit is provided, the cleaning unit includes a body 1, and spray arms 2 are installed on both sides of the body 1. The cleaning unit forms a cleaning area M and at least one high-pressure flushing area N on the surface of the plastic sealing mold. The cleaning area M is formed by a water flow with a smaller impact force, which can clean the surface of the plastic sealing mold. The water flow will drive the impurities remaining on the surface of the plastic sealing mold to flow out of the mold, and the high-pressure flushing area N is formed by a water flow with a larger impact force, which can flush the impurities stuck on the surface of the plastic sealing mold through a larger impact force. The cleaning area M and the high-pressure flushing area N are both used to clean the surface of the plastic sealing mold. There are two high-pressure flushing areas N provided in this embodiment, which can expand the area of ​​the flushing area N. The cleaning unit includes The main body 1 includes a first outlet 4 and a second outlet 5, wherein the first outlet 4 is arranged at the bottom of the main body 1, and the outlet direction of the first outlet 4 is vertically downward and vertically points to the surface of the plastic encapsulation mold, and the second outlet 5 is arranged at the end of the injection wall. The main body 1 is provided with a first connecting pipe 10 and a second connecting pipe 11, wherein the first connecting pipe 10 is connected to the first outlet 4, and the second connecting pipe 11 is connected to the second outlet 5. The first outlet 4 can form a cleaning area M on the mold surface along its outlet direction; the second outlet 5 can form a high-pressure flushing area N on the mold surface along its outlet direction. The second outlet 5 is flat in shape, and the liquid and gas discharged from the second outlet 5 are wide, and the width of the formed high-pressure flushing area N is also large, the flushing area is increased, and the flushing speed can be increased.

[0028] The outlet direction of the first outlet 4 is perpendicular to the surface of the plastic packaging mold. Figure 1 and Figure 2The outlet direction of the first outlet 4 is perpendicular to the surface of the plastic encapsulation mold, and the angle between the outlet direction of the second outlet 5 and the surface of the plastic encapsulation mold is an acute angle. The high-pressure cleaning liquid is obliquely discharged from one side of the impurities, which can quickly remove the impurities attached to the surface of the plastic encapsulation mold; there are two second outlets 5, which are respectively arranged on both sides of the first outlet 4. The opening of the first outlet 4 is larger, and the cleaning liquid discharged from the first outlet 4 flows vertically downward, and the flow rate is lower and the impact force is smaller. The main function is to remove impurities from the mold surface through the flow of liquid. The opening of the second outlet 5 is smaller, and the liquid injection speed is fast, which can impact the mold surface and rinse the mold surface.

[0029] The cleaning area M and the high-pressure flushing area N partially overlap; the first outlet 4 and the second outlet 5 can both discharge cleaning liquid. When the cleaning liquid flows from the first outlet 4 to the cleaning area M, due to the height difference, an obvious water column will be formed at a high place. At the same time, the cleaning liquid discharged from the second outlet 5 directly enters the high-pressure flushing area N. At this time, its pressure is relatively high, and it will cause sputtering after impacting the surface of the plastic encapsulation mold. After these sputtered cleaning liquids contact the turning point of the plastic encapsulation mold, their direction will point to the previously formed water column. Since the flow rate of the cleaning liquid inside the water column is relatively slow, when the high-pressure flushing liquid contacts the water column, its impact force will be weakened to a certain extent, which will lead to a decrease in the flow rate of sputtering to the outside, thereby reducing the speed and distance of the sputtering. Such flow characteristics help to more effectively control the sputtering phenomenon during the cleaning process and improve the cleaning efficiency.

[0030] Embodiment 2

[0031] like Figure 4 As shown, based on the first embodiment, this embodiment can complete the drying work after cleaning, and the specific form is as follows.

[0032] Both the first outlet 4 and the second outlet 5 can blow air to the surface of the plastic encapsulation mold. After the cleaning work is completed, the gas blown out of the first outlet 4 and the second outlet 5 can blow away the residual moisture in the plastic encapsulation mold and speed up its drying speed. The first connecting pipe 10 and the second connecting pipe 11 are both connected to the flow conversion channel, and the flow conversion channel is also connected to the first connecting pipe 8 and the second connecting pipe 13 respectively. Inside the flow conversion channel, there is a rotatable flow conversion wheel 9. The function of this flow conversion wheel 9 is to control the connection state between the connecting pipe and the first connecting pipe 8 or the second connecting pipe 13. The first connecting pipe 8 and the second connecting pipe 13 are respectively used to connect with liquid or gas. Therefore, by rotating the flow conversion wheel 9, switching between different connection states can be achieved. Figure 4, a notch is provided on the commutator wheel 9, and the notch is always connected to the first connecting pipe 10 or the second connecting pipe 11. The commutator wheel 9 can be switched to be connected to the first connecting pipe 8 or the second connecting pipe 13 by rotating. The rotation of the commutator wheel 9 can be driven by a motor. The motor drive is a prior art and is not an innovation of the present invention, so the present invention will not be specifically explained. The cleaning unit can form a drying area m on the surface of the plastic encapsulation mold, and the drying area m is formed on the mold surface by the first outlet 4 along its outlet direction. The drying area m and the cleaning area M overlap. The gas blown out of the first outlet 4 is heated gas. The gas pipeline connected to the first connecting pipe 10 is heated by a heating device. The heating method is a prior art and is not an innovation of the present invention, so the present invention will not be specifically explained. Therefore, the drying area m can be formed, and the hot air can accelerate the drying speed of the plastic encapsulation mold.

[0033] Embodiment 3

[0034] like Figure 5-Figure 7 As shown, based on the second embodiment, this embodiment can remove impurities on the surface of the plastic packaging mold more quickly, and the specific form is as follows.

[0035] The first outlet 4 and the second outlet 5 can both blow air toward the surface of the plastic encapsulation mold. After the cleaning work is completed, the gas blown out of the first outlet 4 and the second outlet 5 can blow away the residual moisture in the plastic encapsulation mold, thereby accelerating its drying speed.

[0036] The air outlet direction of the second outlet 5 can be changed. The root of the spray arm 2 is inserted into the turntable 3 and sleeved on the second connecting pipe 11. The outside of the spray arm 2 is provided with a driving wheel 12. Figure 5 By driving the driving wheel 12 to rotate, the spray arms 2 can be driven to rotate, and the two spray arms 2 can rotate toward both sides to open. The rotation of the driving wheel 12 can be driven by a motor or the like. When the air outlet direction of the second outlet 5 changes, combined with Figure 5 , observed in the direction perpendicular to the surface of the plastic encapsulation mold, the air outlet angle of the second outlet 5 is arranged obliquely, and when the air outlet direction of the second outlet 5 changes, the gas blown out of the second outlet 5 is blown to the surface of the plastic encapsulation mold and then returns, and the overlapping area with the gas blown out of the first outlet 4 becomes smaller. This blowing direction can quickly blow away impurities on the plastic encapsulation mold.

[0037] Embodiment 4

[0038] like Figure 1-Figure 3 As shown, based on the first embodiment, this embodiment can increase the flushing area and improve the flushing speed, and the specific form is as follows.

[0039] The two second outlets 5 can form two high-pressure flushing areas N, and the two high-pressure flushing areas N respectively overlap with the two side parts of the cleaning area M. The two second outlets 5 can both discharge high-pressure cleaning liquid, and the high-pressure cleaning liquid on both sides contacts the two sides of the water column respectively. After being buffered by the water column, the impact force will be weakened to a certain extent, which will lead to a decrease in the flow rate of sputtering toward the outside, thereby reducing the speed and distance of the sputtering.

[0040] Embodiment 5

[0041] like Figure 7 As shown, based on any of the above embodiments, this embodiment provides a frame for supporting a cleaning unit in the following specific form.

[0042] It also includes a slide rail 6 and a fixed frame 7. The slide rail 6 is horizontally arranged above the plastic packaging mold, and the cleaning unit is slidably installed on the slide rail 6 along the length direction of the slide rail 6; the slide rail 6 can slide on the fixed frame 7, and its sliding direction is perpendicular to the sliding direction of the cleaning unit. There are two fixed frames 7, which are respectively arranged on both sides of the plastic packaging mold, and both ends of the slide rail 6 are respectively connected to the fixed frames 7. In this installation method, the cleaning unit can move along the X and Y directions on the surface of the plastic packaging mold, so that the cleaning area M and the high-pressure washing area N can cover the entire plastic packaging mold.
