Description

Technical Field

[0001] This invention belongs to the field of injection molding technology, specifically a fully automatic injection molding device for the shell of a sweeping robot. Background Technology

[0002] With the popularization of smart homes, robotic vacuum cleaners are developing towards higher performance, more exquisite appearance and more compact structure. They integrate deep cavities (for storing dust boxes, water tanks and batteries), dense reinforcing ribs and columns (for enhancing structural strength and installing internal components), as well as complex curved surfaces and snap-fit ​​structures. When traditional injection molding equipment uses a single central gate or a few side gates, the pressure and temperature loss of the plastic melt at the end of the deep cavity is severe, which can easily lead to insufficient filling. Furthermore, at the intersection of reinforcing ribs or in areas with thick walls, the filling is not smooth during cooling and shrinkage, which can easily form internal shrinkage cavities, seriously affecting the structural strength and surface smoothness.

[0003] In addition, due to factors such as uneven distribution of mold filling pressure and different cooling rates, residual stress will be generated inside the product. After demolding or in the use environment, it will be released, causing the shell to warp and twist, affecting the assembly accuracy and product flatness.

[0011] Furthermore, as a preferred embodiment, each of the cut-off pipes is fitted with a compression spring, one end of which is connected to the connecting plate; The outer wall of the intercepting pipe is provided with annular flanges.

[0017] Please see Figures 1-8 In this embodiment of the invention, a fully automatic injection molding device for the shell of a sweeping robot includes: The upper surface of the machine body 1 has an injection area on one side and a mold closing and forming area on the other side. An injection seat 11 is set in the injection area and fixed to the machine body 1. A machine cylinder 12 is horizontally arranged inside the injection seat 11. A material cylinder 13 is vertically connected to the upper end face of the machine cylinder 12. The injection plastic in the material cylinder 13 can flow downward into the machine cylinder 12. A spiral conveying rod is set inside the machine cylinder 12 to realize the spiral extrusion conveying of the injection plastic. The fixed template 2 is vertically fixed to the upper end face of the machine body 1. The fixed template 2 is sealed and connected to the end of the barrel 12 so that the injection plastic in the barrel 12 flows into the fixed template 2. The middle part of the fixed template 2 is set as the main injection channel. The mold closing device 14 is located in the mold closing and forming area and is fixed to the machine body 1; The movable template 3 is vertically arranged and slides horizontally on the upper surface of the machine body 1. The movable template 3 is fixed to the output end of the mold closing device 14, so that the mold closing device 14 can push the movable template 3 to seal with the fixed template 2. The fixed template 2 is also provided with a demolding mechanism. The positioning guide post 15 has one end vertically fixed at the four corners of the fixed template 2, and the moving template 3 has a plurality of positioning holes corresponding to it. The other end of the positioning guide post 15 is slidably connected in the positioning holes.

[0018] In this embodiment, the fixed template 2 includes: The outer protective plate 21 has one side connected to the center of the end of the barrel 12; Connecting plate 22 is fixed on the other side of outer protective plate 21; The concave template 23 is fixed to the end face of the connecting plate 22 away from the outer protective plate 21. A plurality of locking shafts 25 are vertically connected to the outer protective plate 21. Each locking shaft 25 passes through the connecting plate 22 and is connected to the concave template 23. The cooling plate 24 is fixed to the end face of the concave template 23 away from the connecting plate 22, while the outer protective plate 21, the connecting plate 22, the concave template 23 and the cooling plate 24 are all in close contact and fixed.

[0019] In a preferred embodiment, a cooling channel is provided in the cooling plate 24, and multiple connectors 26 are provided on the upper and lower end faces of the cooling plate 24, with each connector 26 connected to both ends of the cooling channel. The connector 26 is connected to an inlet pipe and an outlet pipe respectively. When the coolant enters the cooling channel through the inlet pipe, it can carry away the huge amount of heat from the injection cavity (especially the area near the gate or thick wall) with the shortest path and the largest contact area. Compared with the traditional simple water channel with holes drilled in the mold, the heat exchange efficiency and controllability of the special cooling plate 24 are higher. The arrangement of the cooling channels can be parallel, series-parallel combination, conformal cooling, etc., to ensure that the temperature distribution of the entire cooling plate and even the entire cavity area of ​​the mold 2 is highly uniform.

[0020] In this embodiment, an inner conduit 4 is slidably and sealed within the center of the outer protective plate 21. One end of the inner conduit 4 is deeply connected to the concave template 23, which has a main injection channel. The inner conduit 4 delivers the injection plastic into the concave template 23 through the main injection channel. An annular cavity 41 is formed in the center of the connecting plate 22. Multiple through holes 42 are distributed around the inner wall of the annular cavity 41. Multiple guide holes 44 corresponding to the through holes 42 are formed on the circumferential side wall of the inner conduit 4. In this way, the injection plastic entering the inner conduit 4 can flow into the through holes 42 through the guide holes 44, and then enter the annular cavity 41 through each through hole 42. The connecting plate 22 has multiple auxiliary channels 43, each of which is connected to the annular cavity 41. The concave template 23 has multiple injection micro-holes 5, and the auxiliary channels 43 are connected to the injection micro-holes 5 respectively. Among them, the injection micro-holes 5 are mainly distributed at the bottom of the deep cavity (which can be the bottom or steep sidewall of the deep cavity structure such as the dust box storage compartment, water tank, battery compartment of the robot vacuum cleaner shell), the dense network of reinforcing ribs (rib plates), the root or side of the BOSS column (screw column, buckle column) or the position of complex curved surface, even the corner farthest from the main gate, or the transition area where the wall thickness suddenly becomes thinner. This can ensure the synchronization and integrity of the overall filling, reduce surface flow marks or cold material caused by stagnation, and ensure its shape integrity and strength.

[0021] In this embodiment, an inner spring (not shown in the figure) is connected between the inner guide tube 4 and the outer protective plate 21. The inner spring causes the inner guide tube 4 to slide away from the concave template 23 through its elastic force. At this time, the guide holes 44 and the through holes 42 on the inner guide tube 4 are slidably offset. In this way, the injection plastic in the inner guide tube 4 flows into the concave template 23 through the end of the inner guide tube 4. The inner guide tube 4 is provided with a sealing shaft 45. The sealing shaft 45 is sealed to the end of the inner guide tube 4. A support spring is connected between the sealing shaft 45 and the inner guide tube 4. When the extrusion injection pressure of the injection plastic is higher than 80 MPa, the sealing shaft 45 is in sealing contact with the end of the inner guide tube 4 under the push of the injection plastic. The support spring is fully compressed. At this time, the inner guide tube 4 can slide axially under the push of the injection plastic. At this time, the guide holes 44 and the through holes 42 slide and connect. The injection plastic enters the auxiliary channel 43 through the through holes 42 and finally enters the concave template 23 through the injection micro-holes 5. Therefore, in the injection molding operation, the initial injection pressure can be high (pressure contact 120MP). At this time, the injection plastic enters each auxiliary channel 43 through the annular cavity 41, and finally enters the concave mold 23 through the injection micro-hole 5. After the bottom of the deep cavity and the complex curved surface of the concave mold 23 are initially filled, the injection pressure turns to low pressure. At this time, the support spring and the inner spring elastically reset, the guide hole 44 and the through hole 42 slide and are offset, and the injection plastic enters the main injection channel of the concave mold 23 through the inner guide tube 4. The injection plastic diffuses from the middle of the concave mold 23 and fuses with the initial injection plastic. This process does not require external sensors or program intervention, has a rapid response and high reliability, and greatly improves the melt fusion quality.

[0022] In this embodiment, a plurality of intercepting pipes 51 are sealed and slidably connected inside the connecting plate 22. One end of each intercepting pipe 51 is sealed and slidably connected inside the injection micro-hole 5. A bypass hole 52 is provided on the outer wall of each intercepting pipe 51. The bypass hole 52 is slidably connected to the auxiliary channel 43 one by one. In this way, the injection plastic in the auxiliary channel 43 can enter the intercepting pipe 51 through the bypass hole 52. Multiple hinge rods 53 are distributed around the inner circumference of the injection micro-hole 5. The hinge rods 53 are rotatably connected to the inner wall of the concave template 23. The wall of the intercepting pipe 51 is provided with an oblique guide. One end of each hinge rod 53 is obliquely inserted into the oblique guide. The end of each hinge rod 53 is provided with an intercepting frame 54. When the intercepting pipe 51 is at the leftmost position in the connecting plate 22, the bypass hole 52 and the auxiliary channel 43 are slidably offset, and each intercepting frame 54 contacts and cooperates with each other, thereby cutting off the injection plastic conveyed in the intercepting pipe 51.

[0023] In a preferred embodiment, each of the cut-off pipes 51 is fitted with a compression spring, one end of which is connected to the connecting plate 22. The compression spring can make the cut-off pipe 51 located on the leftmost side of the connecting plate 22 through the elastic force of the compression spring. The outer wall of each intercepting pipe 51 is provided with annular flanges 55. Each annular flange 55 is slidably connected to the connecting plate 22 by a rubber ring. The bypass hole 52 and the auxiliary channel 43 are slidably offset by the elastic force of the compression spring. When the injection pressure in the auxiliary channel 43 is greater than the elastic force of the compression spring, it can push the intercepting pipe 51 to slide axially. At this time, the bypass hole 52 and the auxiliary channel 43 gradually connect, and the injected plastic can flow into the intercepting pipe 51. Meanwhile, the intercepting frame 54 at the end of the intercepting pipe 51 separates, and the injected plastic can flow into the concave template 2. 3. Furthermore, different specifications of compression springs can be used on each cut-off tube 51, which can push the cut-off tube 51 to slide open after the injection pressure reaches a certain strength, thereby enabling the injection micro-holes 5 at corresponding positions in the concave template 23 to be injected with injection plastic in sequence. Traditional systems use multiple injection points to feed material at the same time, and the pressure is evenly distributed, which often leads to insufficient pressure in difficult-to-fill areas and excessive pressure in easy-to-fill areas. In this device, at the beginning of injection, the injection pressure is adjusted to ensure that the most difficult-to-fill area (such as the deepest cavity) receives high-pressure injection plastic first. As the pressure continues to rise, the remaining injection micro-holes 5 open in sequence, corresponding to the less difficult and easier-to-fill areas respectively.

[0024] In this embodiment, the moving template 3 includes: The transfer plate 31 is fixed to the mold closing device 14. Two limiting blocks 32 are symmetrically fixed on one side end face of the transfer plate 31, and two fixing rods are vertically fixed on each limiting block 32. The moving mold frame 33 is fixed to the limiting block 32 by a fixing rod; The convex template 34 is slidably installed in the moving mold frame 33, and the convex template 34 and the concave template 23 cooperate to form an injection cavity; The heat-conducting plate 35 is fixed on the side of the moving mold frame 33 away from the limiting block 32. The heat-conducting plate 35 has a heat flow channel. The heat-conducting plate 35 can preheat at high temperature before injection molding, thereby avoiding the phenomenon of material shortage in the injection cavity caused by solidification of the injection plastic.

[0025] In this embodiment, four pillars 36 are symmetrically fixed on one side of the transfer plate 31 and between two limiting blocks 32. A micro-vibration plate 37 is provided between the two limiting blocks 32. The micro-vibration plate 37 is slidably connected to each of the pillars 36. Multiple shafts 38 are distributed on one end face of the micro-vibration plate 37. The micro-vibration plate 37 is fixed to the convex template 34 through the shafts 38. In this way, the convex template 34 can vibrate synchronously with the micro-vibration plate 37, so as to fully compact the plastic injected into the injection cavity, effectively reduce the residual orientation stress "frozen" inside the plastic due to high-speed injection and rapid cooling, prevent product warping and deformation, and improve the overall mechanical strength of the robot vacuum cleaner shell to a certain extent. It should be noted that when the convex template 34 vibrates, the distance between it and the concave template 23 decreases, the compression effect is significant, but there will be no contact between the convex template 34 and the concave template 23, avoiding collision, crushing or wear of the cavity surface due to uncontrolled vibration, which would cause damage to the template.

[0026] In this embodiment, a guide shaft is fixed to the other end face of the micro-vibration plate 37. The guide shaft is slidably connected to the transfer plate 31. The mold closing device 14 is provided with a loading shaft 6. One end of the loading shaft 6 is coaxially connected to the guide shaft. Micro-vibrators 61 are distributed between the loading shaft 6 and the guide shaft. The loading shaft 6 can move and adjust the convex template 34 in axial sliding, thereby changing the distance between the convex template 34 and the concave template 23. The micro-vibrators 61 can provide axial vibration to the guide shaft so as to realize micro-vibration of the convex template 34 body.

[0027] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
