Description

Technical Field

[0001] The invention relates to the technical field of silica gel circulation, in particular to a silica gel circulation mold and a method for accurately controlling the silica gel flow rate. Background Art

[0002] Silicone has been widely used due to its good non-toxicity and chemical stability. Most silicone products are made by silicone molds, in which silicone flows into the mold cavity through silicone flow channels.

[0003] In the prior art, silicone passes through the main flow channel of the silicone flow channel, and then enters the mold cavity through multiple branch flow channels. In order to control the flow rate of silicone, two guide plates are added to the main flow channel, and guide holes are evenly opened on the two guide plates. The size of the guide holes between the two guide plates is controlled to achieve the control of the silicone flow rate per unit time.

[0004] Since the number and aperture of the guide holes are fixed, the flow rate adjustment range of silicone is small and the adjustment is inconvenient. In addition, during use, for the fixed silicone flow rate parameters, once the adjustment is completed, no further adjustment will be made during the process. In the actual working process, the silicone flow rate is often affected by many factors and it is difficult to always maintain near the predetermined silicone flow rate parameters. For example, the influence of silicone temperature. When the temperature rises, the interaction force between silicone molecular chains decreases, resulting in an increase in the flow rate of silicone. In addition, silicone molecular chains and cross-linked chains will break under high temperatures, thereby affecting its flow rate, that is, the silicone flow rate per unit time. These will affect the quality of silicone products, such as causing the silicone to not be evenly coated on the surface of the data cable. Summary of the invention

[0011] In a possible implementation, the silicone flow control mechanism includes a servo motor and a fixed plate and a circular adjustment plate arranged in parallel along the radial direction of the columnar silicone flow channel in the columnar silicone flow channel, wherein the servo motor is installed at one end of the housing close to the feed port, and the rotating shaft of the servo motor is coaxially connected with an adjustment shaft, and the adjustment shaft extends into the columnar silicone flow channel along the axial direction of the columnar silicone flow channel, and a transmission gear is fixedly sleeved thereon, wherein the circular adjustment plate is close to the feed port, and the circular adjustment plate is uniformly provided with a plurality of arc-shaped limiting spaces along the annular direction, and the fixed plate is fixedly installed in the columnar silicone flow channel and is uniformly provided with an arc-shaped limiting space along the annular direction. A plurality of linear limiting spaces are provided, and a plurality of fan-shaped baffle blades are arranged between the circular adjustment plate and the fixed plate. The plurality of fan-shaped baffle blades cooperate with each other to form a complete circle, and the tips of the plurality of fan-shaped baffle blades cooperate with each other to form the adjustment channel. The top and bottom surfaces of each fan-shaped baffle blade are respectively provided with columnar protrusions and strip protrusions corresponding to the arc-shaped limiting space and the corresponding linear limiting space. The outer circumference of the circular adjustment plate is provided with external teeth meshing with the transmission gear, so that when the servo motor drives the circular adjustment plate to rotate, the plurality of fan-shaped baffle blades can synchronously directional deflect and change the opening of the adjustment channel.

[0012] In a possible implementation, the circular adjustment plate and the fixed plate are provided with corresponding limited flow channels near the center.

[0016] Beneficial effects: Compared with the prior art, the silicone flow mold and the method for accurately controlling the silicone flow provided by the present application can accurately control the flow rate of silicone in the silicone mold within a unit time within a predetermined threshold range by real-time monitoring the flow rate of silicone in the shunt channel in the silicone mold and making real-time adjustments when the flow rate exceeds a predetermined threshold range, and the control accuracy is high, thereby effectively ensuring the quality of silicone products;

[0017] The flow rate of silica gel fed into the diversion channel is controlled by changing the opening size of the adjustment channel, which is convenient to adjust and has a large adjustment range.

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0027] Those skilled in the art should understand that, in the disclosure of the specification, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0028] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0029] A first aspect of an embodiment of the present application provides a method for accurately controlling the flow rate of silica gel, comprising the following steps:

[0030] During the process of silicone flowing through the silicone mold, the flow rate of silicone flowing through the diverter channel in the silicone mold is monitored in real time by a flow sensor. When the flow rate of silicone flowing through the diverter channel in the silicone mold exceeds a predetermined threshold range, the flow rate of silicone fed into the diverter channel is automatically adjusted accordingly to restore the flow rate of silicone flowing through the diverter channel in the silicone mold to within the predetermined threshold range, that is, the silicone flows out of the silicone mold at a flow rate within the predetermined threshold range. In this way, the real-time monitoring and adjustment method can be used to ensure that the circulation volume of silicone per unit time is always maintained within the predetermined threshold range, thereby effectively ensuring the output quality of silicone and the quality of silicone products.

[0031] Under different conditions, for example, for silicone products with different molding thicknesses, and for silicone with different formulas and ratios, the preset threshold range may be different. This difference is mainly reflected in two aspects. On the one hand, the middle value of the preset threshold range may be different, which may be 100g or 130g. On the other hand, the upper and lower deviations of the preset threshold range may be different, which may be ±5g or ±2g. These can be adjusted and precisely controlled according to actual conditions.

[0032] In one embodiment, the silicone mold is provided with a columnar silicone flow channel, and a silicone flow control mechanism and a diverter are sequentially arranged in the columnar silicone flow channel along the silicone flow direction, wherein the silicone flow control mechanism forms an adjustment channel with adjustable opening at the center of the columnar silicone flow channel, and the silicone flows into the diverter channel through the adjustment channel, and the amount of silicone flowing into the diverter channel per unit time is determined by the opening size of the adjustment channel. Compared with the method of pre-setting the size of the guide hole, the flow rate of silicone per unit time is easier to be flexibly controlled, wherein the end of the diverter close to the silicone flow control mechanism is conical, and the tip of the cone is facing the adjustment channel, and the diverter channel is evenly arranged on the periphery of the diverter and penetrates the diverter along the axial direction of the columnar silicone flow channel to ensure that the silicone can flow out evenly.

[0033] Further preferably, the flow rate of the silicone flowing through the diverter channel in the silicone mold is monitored in real time by a flow sensor arranged in the diverter channel, and the monitoring stability is good and the monitoring accuracy is high. At the same time, when the flow rate of the silicone flowing through the diverter channel in the silicone mold exceeds the predetermined threshold range, the flow sensor sends a signal to the controller, and then the controller controls the rotation angle of the rotating shaft of the servo motor to adjust the opening of the regulating channel. For example, when the flow rate of the silicone flowing through the diverter channel in the silicone mold is low, the opening of the regulating channel is increased by the servo motor, or when the flow rate of the silicone flowing through the diverter channel in the silicone mold is high, the opening of the regulating channel is reduced by the servo motor. Since the rotation angle of the servo motor can be precisely controlled, the opening of the regulating channel can also be precisely controlled accordingly, so that the flow rate of the silicone can be precisely controlled.

[0034] The second aspect of the embodiment of the present application provides a silicone circulation mold for realizing the method of accurately controlling the flow rate of silicone as described above, referring to Figures 1 to 6, wherein the silicone flow mold comprises a housing 10, the silicone flow control mechanism 20 and the flow divider 30, wherein the outer surface of the housing 10 is coated with a heat-insulating layer 11, which is used to ensure the temperature environment in the silicone flow mold so that the silicone can flow normally. The housing 10 has a columnar silicone flow channel 101 and a feed port 102 and a discharge port 103 formed at opposite ends of the columnar silicone flow channel 101, wherein silicone is injected into the columnar silicone flow channel 101 through the feed port 102, and after the silicone flows through the columnar silicone flow channel 101, it flows out from the discharge port 103. The silicone flow control mechanism 20 and the diverter 30 are sequentially arranged in the columnar silicone flow channel 101, and the diverter 30 is close to the discharge port 103. At the same time, a flow sensor is installed in the diverter channel 301 of the diverter 30, wherein the flow sensor is connected to the silicone flow control mechanism 20 through a controller electrical signal, so that when the flow rate of the silicone flowing through the diverter channel in the silicone mold exceeds a predetermined threshold range, the silicone flow control mechanism 20 automatically adjusts the flow rate of the silicone delivered into the diverter channel 301 per unit time accordingly, thereby ensuring that the unit flow rate of the silicone in the silicone circulation mold is always maintained within the predetermined threshold range through real-time precise adjustment, thereby effectively ensuring the quality of the silicone products.

[0035] In one embodiment, the silicone flow control mechanism 20 includes a servo motor 21 and a fixed plate 22 and a circular adjustment plate 23 which are arranged in parallel along the radial direction of the columnar silicone flow channel 101 in the columnar silicone flow channel 101, wherein the servo motor 21 is installed at one end of the housing 10 close to the feed port 102, and the rotating shaft of the servo motor 21 is coaxially connected with an adjustment shaft 24, and the adjustment shaft 24 extends into the columnar silicone flow channel 101 along the axial direction of the columnar silicone flow channel 101, and is fixedly sleeved with a transmission gear 25, wherein the circular adjustment plate 23 is close to the feed port 102, and the circular adjustment plate 23 is uniformly provided with a plurality of arc-shaped limiting spaces 201 along the annular direction, wherein the fixed plate 22 is fixedly installed in the columnar silicone flow channel 101, and is uniformly opened along the annular direction. A plurality of linear limiting spaces 202 are provided. In addition, a plurality of fan-shaped baffles 26 are provided between the circular adjustment plate 23 and the fixed plate 22, wherein the plurality of fan-shaped baffles 26 cooperate to form a complete circle, and the tips of the plurality of fan-shaped baffles 26 cooperate with each other to form the adjustment channel 104, and at the same time, the top surface and the bottom surface of each fan-shaped baffle 26 are respectively provided with a columnar protrusion 261 and a strip protrusion 262 corresponding to the corresponding arc-shaped limiting space 201 and the corresponding linear limiting space 202, that is, each fan-shaped baffle 26 corresponds to each arc-shaped limiting space 201 and each linear limiting space 202, and at the same time, each columnar protrusion 261 cooperates with the corresponding arc-shaped limiting space 201, and each strip protrusion 262 cooperates with the corresponding linear limiting space 202. The outer circumference of the circular adjustment plate 23 is provided with external teeth meshing with the transmission gear 24 , so that when the servo motor 21 drives the circular adjustment plate 23 to rotate, the plurality of fan-shaped baffles 26 can be synchronously directional and deflected to change the opening of the adjustment channel 104 .

[0036] Specifically, when the flow sensor detects that the flow of silicone flowing through the diversion channel 301 in the silicone mold exceeds a predetermined threshold range, the flow sensor sends a signal to the controller, and the controller sends a signal to the servo motor 21 in a wired or wireless manner to control the servo motor 21 to operate, and the circular adjustment plate 23 is driven to rotate in a directional manner through the adjustment shaft 24. When the columnar protrusion 261 and the strip protrusion 262 of the fan-shaped baffle 26 are respectively matched with the arc-shaped limit space 201 and the linear limit space 202, the circular adjustment plate 23 drives the fan-shaped baffle 26 to rotate in a directional manner. The outer end of the fan-shaped baffle 26 has a relatively large deflection amplitude and deflects along an arc, while the tip of the fan-shaped baffle 26 has a relatively small deflection amplitude and moves along a straight line, so that the tips of the fan-shaped baffle 26 can be relatively deflected closer or relatively deflected away from each other, thereby accurately adjusting the size of the adjustment channel 104, wherein there is a relatively accurate positive correlation between the deflection movement of the fan-shaped baffle 26 and the rotation angle of the servo motor 21, so that the opening of the adjustment channel 104 can be accurately controlled by the servo motor 21, thereby realizing real-time and accurate control of the silicone flow.

[0037] In one embodiment, the circular adjustment plate 23 and the fixed plate 22 are provided with corresponding limited flow channels 203 near the center position, so that a maximum channel for the columnar silicone flow channel 101 to flow to the diverter 30 can be formed through the limited flow channel 203, that is, an upper limit of the flow rate is formed, while the opening of the adjustment channel 104 is not hindered from being adjusted by the fan-shaped baffle 26.

[0038] In one embodiment, the arc-shaped limiting space 201 and the linear limiting space 202 are both through grooves.

[0039] In another embodiment, the circular adjustment plate 23 is located above the fixed plate 22 , and the arc-shaped limiting space 201 is a groove arranged at the bottom of the circular adjustment plate 23 , and the linear limiting space 202 is a groove arranged at the top of the fixed plate 22 .

[0040] In one embodiment, the columnar silicone flow channel 101 is connected to an annular mounting plate 12 at the outer edge of the bottom of the fixing plate 22 to facilitate the installation of the fixing plate 22. At the same time, the columnar silicone flow channel 101 is also provided with a limiting plate 13 on the top of the circular adjustment plate 23, and the limiting plate 13 and the circular adjustment plate 23 are slidably matched to limit the circular adjustment plate 23 at the top. At the same time, the bottom of the circular adjustment plate 23 is coaxially connected with a guide ring 231, wherein the guide ring 231 is located on the outside of the fan-shaped baffle 26, and the A limiting groove cooperating with the guide ring 231 is provided on the top of the fixed plate 22, which is used to ensure that the circular adjustment plate 23 does not deviate from its position when the servo motor 21 drives the circular adjustment plate 23 to rotate. In this way, the upper part of the circular adjustment plate 23 is limited by the limiting plate 13, and the lower part of the circular adjustment plate 23 is limited by the fan-shaped baffle 26 and the fixed plate 22, so that it can be limited in the height direction. At the same time, based on the matching relationship between the guide ring 231 and the limiting groove, it can also be limited in the horizontal direction, which can ensure the stability and accuracy of the rotation of the circular adjustment plate 23.
