Description

Technical Field

[0001] This utility model relates to the field of injection molding technology for sweeping robots, and in particular to an injection mold for processing sweeping robots. Background Technology

[0002] A robotic vacuum cleaner is a type of smart home appliance that can automatically clean floors in a room using a certain level of artificial intelligence. The outer shell of a robotic vacuum cleaner is injection molded.

[0003] The processing equipment corresponding to injection molds is a plastic injection molding machine. The plastic is first heated and melted in the heating barrel at the bottom of the injection machine. Then, driven by the screw or plunger of the injection machine, it enters the mold cavity through the injection nozzle and the mold's gating system. The plastic cools and hardens, and the product is obtained by demolding. Existing injection molds have some drawbacks. After injection molding, demolding is inconvenient. Most current solutions involve ejecting the product using ejector pins. However, the contact area between the ejector pins and the product is small, which can easily damage the product during ejection, causing deformation of the ejection area and affecting the product's precision. Therefore, we provide an injection mold for processing robotic vacuum cleaners to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an injection mold for processing sweeping robots.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an injection mold for processing a sweeping robot, including a lower fixed plate and an upper fixed plate. Two mold feet are installed on the upper end of the lower fixed plate, and a lower mold is provided on the upper end of the mold feet. An upper mold is connected to the lower end of the upper fixed plate. The upper mold and the lower mold are fitted together at corresponding ends. A mold groove is provided in the middle of the lower mold. Bottom grooves are provided at equal intervals at the lower end of the lower mold. A top groove is provided at the top of the inner cavity of the bottom groove. A stripping mechanism is provided in the inner cavity of the bottom groove. The top of the stripping mechanism passes through the top groove and is inserted into the mold groove.

[0007] The stripping mechanism includes a top column that is inserted into the mold groove. A fixing plate is installed on the outer side of the top column. A second spring is connected to the lower end of the fixing plate. A mounting plate is connected to the lower end of the second spring. The mounting plate is screwed to the bottom groove. A pushing component connected to the bottom groove is provided at the lower middle part of the lower mold.

[0008] Preferably, the pushing assembly includes an air pipe connector installed in the middle of the lower end of the lower mold, with an air pipe connected to the lower end of the air pipe connector. A central hole is provided in the middle of the lower end of the lower mold, and air holes are connected to the central hole and multiple bottom grooves. The position of the air holes is higher than the position of the fixed plate, and the inner diameter of the bottom groove is larger than the inner diameter of the top groove.

[0009] Preferably, the inner wall of the central hole is equidistantly connected with flow dividers, and the flow dividers are designed to be integrated.

[0010] Preferably, the upper end of the lower mold is provided with a second positioning hole around its perimeter, and the upper end of the upper mold is provided with a first positioning hole corresponding to the position around its perimeter. A positioning pin is inserted into the inner cavity of the first positioning hole and the second positioning hole corresponding to each position. A support column is movably sleeved in the inner cavity of the positioning pin. A first spring is connected to the lower end of the positioning pin. The lower ends of the support column and the first spring are both installed on the upper end of the mold foot.

[0011] Preferably, the upper end of the lower mold is symmetrically provided with positioning grooves, and the lower end of the upper mold is symmetrically connected with positioning blocks that engage with it.

[0012] Preferably, the lower fixing plate has a through hole in the middle, and the lower end of the lower fixing plate has a central groove that communicates with the through hole. The lower end of the air pipe passes through the through hole and extends into the inner cavity of the central groove.

[0013] The injection mold for processing a sweeping robot proposed in this utility model has the following advantages:

[0014] 1. High-pressure gas, after being evenly distributed, enters the bottom and top slots. The high-pressure air cannot be discharged from the top slot, thus compressing the fixed plate downwards. This causes the fixed plate to press down on the second spring and move the ejector pin downwards. Subsequently, more high-pressure air is discharged upwards to impact the sprue at the bottom of the product. This facilitates demolding of the product through the impact of the high-pressure air. When the high-pressure air impacts and demolds the product, it creates a small gap between the bottom of the product and the mold slot, allowing more high-pressure air to enter the gap. This results in a larger ejection area, avoiding the damage to the product caused by the small contact area between the ejector pin and the product during traditional ejection pin ejection. This effectively prevents deformation of the ejection part from affecting the product's precision, thus effectively improving the demolding effect.

[0015] 2. When the upper mold moves downward, the positioning pin passes through the first positioning hole and presses against the upper fixed plate. The upper fixed plate then presses down on the positioning pin, which in turn presses down on the support column and the first spring. This effectively buffers the mold during closing, reduces the impact caused by the downward movement of the upper mold and the lower mold, and protects the mold. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-2 As shown, an injection mold for processing a sweeping robot includes a lower fixed plate 1 and an upper fixed plate 5. Two mold feet 2 are installed on the upper end of the lower fixed plate 1. A lower mold 3 is provided on the upper end of the mold feet 2. An upper mold 4 is connected to the lower end of the upper fixed plate 5. The upper mold 4 and the lower mold 3 are fitted together at their corresponding ends. The upper end of the lower mold 3 is provided with second positioning holes 9 around its upper periphery. The upper end of the upper mold 4 is provided with first positioning holes 7 corresponding to the positions. Positioning pins 10 are inserted into the inner cavities of the first positioning holes 7 and the second positioning holes 9 corresponding to each position. Support columns 11 are movably sleeved in the inner cavity of the positioning pins 10. A first spring 12 is connected to the lower end of the positioning pins 10. The lower ends of the support columns 11 and the first spring 12 are both installed on the upper end of the mold feet 2. Positioning grooves 13 are symmetrically provided on the upper end of the lower mold 3. Positioning blocks 8 that are engaged with the lower end of the upper mold 4 are symmetrically connected to the lower end of the lower mold 4.

[0023] When this mold is in use, the lower mold 3 is placed on the upper end of the mold foot 2, and the second positioning hole 9 at the upper end of the lower mold 3 is inserted into the positioning pin 10 to limit the installation of the lower mold 3. Then, when the mold is closed, the upper mold 4 moves down and fits into the lower mold 3. The first positioning hole 7 at the upper end of the upper mold 4 is also inserted into the positioning pin 10 to accurately position the mold closing operation. Subsequently, the positioning block 8 at the lower end of the upper mold 4 is engaged in the positioning groove 13 at the upper end of the lower mold 3, which further improves the accurate positioning effect of the mold closing. When the upper mold 4 moves down, the positioning pin 10 passes through the first positioning hole 7 and abuts against the upper fixed plate 5. Then, the upper fixed plate 5 presses down the positioning pin 10, which in turn presses down the support column 11 and the first spring 12, which effectively provides a buffering effect during mold closing and reduces the impact effect caused by the downward movement of the upper mold 4 and the lower mold 3, thus protecting the mold.

[0024] Reference Figure 2-4 As shown, a mold groove is provided in the middle of the lower mold 3, and bottom grooves 15 are provided at equal intervals at the lower end of the lower mold 3. A top groove 14 is provided at the top of the inner cavity of the bottom groove 15. A stripping mechanism 6 is provided in the inner cavity of the bottom groove 15. The top of the stripping mechanism 6 passes through the top groove 14 and is inserted into the mold groove. The stripping mechanism 6 includes a top post 19 that is inserted into the mold groove. A fixing plate 18 is installed on the outer side of the top post 19. A second spring 17 is connected to the lower end of the fixing plate 18. A mounting plate 16 is connected to the lower end of the second spring 17. 16 is screwed to the bottom groove 15. The lower mold 3 is provided with a pushing component connected to the bottom groove 15 at the middle of its lower end. The pushing component includes an air pipe connector 22 installed at the middle of the lower end of the lower mold 3. An air pipe 23 is connected to the lower end of the air pipe connector 22. A center hole 21 is provided at the middle of the lower end of the lower mold 3. An air hole 20 is connected to multiple bottom grooves 15. The position of the air hole 20 is higher than the position of the fixed plate 18. The inner diameter of the bottom groove 15 is larger than the inner diameter of the top groove 14.

[0025] After the injection molding is completed and the mold is demolded, the air pipe is connected to an external gas delivery device to deliver high-pressure air. The high-pressure air then passes through the air pipe connector 22 and enters multiple air holes 20, and then enters the bottom groove 15 and the top groove 14. Since the ejector pin 19 is tightly inserted into the mold groove and is in close contact with the sprue at the bottom of the product, the high-pressure air cannot be discharged from the top groove 14. This causes the fixed plate 18 to be compressed downward, which in turn presses down the second spring 17 and drives the ejector pin 19 to move downward. Subsequently, more high-pressure air is discharged upward to impact the sprue at the bottom of the product, which facilitates the demolding of the product through the impact of the high-pressure air. When the high-pressure air impacts the demolded product, it creates a small gap between the bottom of the product and the mold groove, which allows more high-pressure air to enter the gap. This results in a larger ejection area and avoids the damage to the product caused by the small contact area between the ejector pin and the product when ejecting products with traditional ejector pins.

[0026] The inner wall of the central hole 21 is equidistantly connected with flow dividers 24. The flow dividers 24 are integrated and connected in an effective manner to uniformly cut and divide the conveyed gas through multiple flow dividers 24, so that the gas is uniformly conveyed to multiple sets of air holes 20. This effectively improves the uniformity of gas delivery, thereby increasing the uniformity of ejection force at different positions at the bottom of the product, improving the uniformity of demolding thrust, and improving the stability of demolding.

[0027] The lower fixing plate 1 has a through hole 25 in the middle and a central groove 26 connected to the through hole 25 at the lower end. The lower end of the air pipe 23 passes through the through hole 25 and extends into the inner cavity of the central groove 26, so that the air pipe 23 can pass through the through hole 25 and be discharged along the central groove 26 when in use, and can be connected to an external gas delivery device for easy use.

[0028] Working Principle: When the mold is demolded after injection molding, this utility model connects to an external gas delivery device via an air pipe, thereby delivering high-pressure air. The high-pressure air then passes through the air pipe connector 22 and enters the central hole 21. The gas is evenly cut and distributed by the multi-component flow plate 24 in the central hole 21, facilitating the uniform delivery of gas to multiple sets of air holes 20. This effectively improves the uniformity of gas delivery. Subsequently, the gas enters the bottom groove 15 and the top groove 14. The high-pressure air cannot be discharged from the top groove 14, thus compressing the fixed plate 18 downward. The fixed plate 18 then presses down the second spring 17 and drives the ejector pin 19 to move downward. Subsequently, more high-pressure air is discharged upward to impact the sprue at the bottom of the product, facilitating demolding through the impact of the high-pressure air. When the high-pressure air impacts the demolded product, it creates a small gap between the bottom of the product and the mold groove, allowing more high-pressure air to enter the gap. This results in a larger ejection area, avoiding the damage to the product caused by the small contact area between the ejector pin and the product during traditional ejection pin ejection.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
