Description

[0002] At present, with the popularization of smart homes, sweeping robots are developing towards higher performance, more delicate appearance and more compact structure, and the sweeping robots integrate deep cavities (for accommodating dust boxes, water tanks and batteries), dense reinforcing ribs and columns (for enhancing structural strength and mounting internal components) and complex curved surfaces and buckle structures.

[0003] When the traditional injection molding equipment adopts a single central gate or a small number of side gates, the pressure and temperature loss of the plastic melt flowing to the deep cavity end is serious, which easily leads to insufficient filling, and when the reinforcing ribs intersect or the wall thickness area is cooled and shrinks, the filling is not smooth, and internal shrinkage holes are easily formed, which seriously affects the structural strength and surface flatness.

[0060] A plurality of auxiliary channels 43 are formed in the joint plate 22, each of the auxiliary channels 43 is communicated with the annular cavity 41, and a plurality of injection micro-holes 5 are formed in the recessed die plate 23, the auxiliary channels 43 are respectively communicated with the injection micro-holes 5, among which, the injection micro-holes 5 are mainly distributed at the bottom of the deep cavity (which can be the bottom of the dust box storage bin, water tank groove, battery compartment and other deep cavity structures of the robot cleaner shell or steep side wall), the dense rib (rib plate) network, the root or side or complex curved surface position of the BOSS column (screw column, buckle column), or even the corner farthest from the main gate, or the transition area where the wall thickness suddenly thins, so as to ensure the synchronization and integrity of the overall filling, reduce the surface flow marks or cold material caused by flow stagnation, and ensure the shape integrity and strength.

[0061] In the embodiment, an inner spring (not shown in the figure) is connected between the inner guide pipe 4 and the outer cover plate 21, and the inner spring makes the inner guide pipe 4 slide away from the recessed die plate 23 by elastic force, at this time, each flow guide hole 44 on the inner guide pipe 4 is slidingly misaligned with the through hole 42, so that the injection material in the inner guide pipe 4 flows into the recessed die plate 23 through the end of the inner guide pipe 4, and the inner guide pipe 4 is provided with a sealing shaft 45, the sealing shaft 45 is sealingly matched with the end of the inner guide pipe 4, and a supporting spring is connected between the sealing shaft 45 and the inner guide pipe 4, among which, when the extrusion injection pressure of the injection material is higher than 80MP, the sealing shaft 45 is in sealing contact with the end of the inner guide pipe 4 under the pushing of the injection material, and the supporting spring is completely compressed, at this time, the inner guide pipe 4 can slide axially under the pushing of the injection material, at this time, the flow guide hole 44 is slidably connected with the through hole 42, the injection material enters the auxiliary channel 43 through the through hole 42, and finally enters the recessed die plate 23 through the injection micro-hole 5;

[0062] Therefore, in the injection operation, the initial injection pressure can be high pressure (pressure contact 120MP), at this time, the injection material enters each auxiliary channel 43 through the annular cavity 41, and finally enters the recessed die plate 23 through the injection micro-hole 5, when the deep cavity bottom and complex curved surface of the recessed die plate 23 are preliminarily filled, the injection pressure is converted to low pressure, at this time, the supporting spring and the inner spring are elastically reset, the flow guide hole 44 is slidably misaligned with the through hole 42, the injection material enters the main injection channel of the recessed die plate 23 through the inner guide pipe 4, and the injection material diffuses from the middle of the recessed die plate 23 and is fused with the preliminary injection material, this process does not need external sensor or program intervention, the response is fast, the reliability is high, and the melt fusion quality is greatly improved.

[0063] In the embodiment, a plurality of cut-off pipes 51 are sealingly and slidably connected in the joint plate 22, one end of each of the cut-off pipes 51 is sealingly and slidably connected in the injection micro-hole 5, and bypass holes 52 are formed in the outer wall of each of the cut-off pipes 51, the bypass holes 52 are slidably and communicatively connected with the auxiliary channels 43 one by one, so that the injection material in the auxiliary channels 43 can enter the cut-off pipes 51 through the bypass holes 52;

[0065] As a preferred embodiment, a compression spring is sleeved on each of the cut-off pipes 51, one end of the compression spring is connected with the connecting plate 22, and the compression spring can make the cut-off pipe 51 located at the leftmost side in the connecting plate 22 by the elastic force of the compression spring;

Further, different specifications of compression springs can be used on each of the cut-off pipes 51, which can slide the cut-off pipe 51 to open after the injection molding pressure reaches a certain strength, so that the injection molding micro-holes 5 at the corresponding positions in the cavity plate 23 can be sequentially injected with injection molding material. In the traditional system, multiple injection points are used for feeding at the same time, and the pressure is evenly dispersed, which often leads to insufficient pressure in difficult-to-fill areas and excessive pressure in easy-to-fill areas. In the device, the corresponding most difficult-to-fill area (such as the deepest cavity) can be preferentially obtained by the high-pressure injection molding material through the injection molding pressure adjustment when the injection molding starts. With the continuous rise of the pressure, the remaining injection molding micro-holes 5 are sequentially opened, respectively corresponding to the second difficult-to-fill area and the easy-to-fill area.

A plurality of shaft columns 38 are distributed on one end surface of the micro-vibration plate 37, and the micro-vibration plate 37 is fixed with the male die plate 34 through the shaft columns 38. In this way, the male die plate 34 can vibrate synchronously with the micro-vibration plate 37, so as to realize sufficient compaction of the injection material in the injection cavity, effectively reduce the residual orientation stress frozen in the plastic due to high-speed injection and rapid cooling, and prevent product warping and deformation, thereby improving the overall mechanical strength of the outer shell of the robot in a certain extent. It should be noted that when the male die plate 34 vibrates, the distance between the male die plate 34 and the female die plate 23 is reduced, and the extrusion effect is remarkable, but the male die plate 34 and the female die plate 23 will not touch, so as to avoid the collision, pressure injury or wear of the cavity surface caused by uncontrolled vibration, and cause damage to the die plate.
