TECHNICAL FIELD

[0002] The existing production equipment for a vehicle auxiliary handle cover plate mainly includes an injection molding machine and a matched mold, a gas-assisted forming equipment, a water chiller, a trimming machine, a visual inspection machine, and an automatic pry cover plate tool. For the injection mold of the existing production equipment for a vehicle auxiliary handle cover plate, it is usually composed of a fixed mold and a movable mold. The fixed mold side includes a fixed mold bottom plate, a hot runner plate, and a fixed mold plate. The movable mold side has a movable mold plate and a movable mold bottom plate. After the two are combined, a cavity matching the shape of the cover plate is formed. A plurality of cooling channels are provided in the mold, and the cooling channels are connected to the water chiller through inlet and outlet water pipelines to quickly cool the molded plastic parts.
[0003] In actual production, whether the mold cavity is full during the injection molding process depends mainly on the experience of the operator or the preset time. It is not convenient to monitor in real time, and the product may be short of material due to insufficient filling, or flash may be generated due to overfilling, which requires subsequent trimming processing to increase costs. Moreover, the existing cooling system usually starts cooling after the injection molding begins. If the mold is not full, the cooling liquid may cause the local plastic to solidify prematurely, affecting the molding quality and increasing energy consumption. In addition, during the cooling process, the end of the injection liquid at the conveying pipeline is prone to slight solidification due to the continuous action of the cooling system or the influence of the environmental temperature. When the injection is performed again, the solidified end will mix with the new molten plastic, causing defects such as impurities and bubbles in the product, further affecting the product quality.

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. EMBODIMENT
[0024] At present, there is a lack of real-time monitoring of the filling state of the mold cavity in the injection molding process, which leads to product material shortage or flash, a lack of linkage between the cooling system and the injection molding process, which leads to local solidification or high energy consumption, and the end of the injection liquid at the conveying pipeline 121 is prone to solidification, which affects the quality of subsequent products. Please refer to Figure 1 Figure 8 A vehicle auxiliary handle cover production equipment is shown in the drawing, which comprises a base 1, the top of the base 1 is provided with an extrusion device 12, the end of the extrusion device 12 is provided with an injection head 120, the top of the base 1 is provided with a guide assembly 13, the inside of the guide assembly 13 is provided with a conveying pipeline 121, and the conveying pipeline 121 and the injection head 120 are provided with a flow sensor 122; The inside of the guide assembly 13 is provided with a No. 1 cylinder 14, the end of the No. 1 cylinder 14 and the guide assembly 13 are provided with a compression molding assembly 15, the compression molding assembly 15 and the guide assembly 13 are provided with a mold assembly 16, the mold assembly 16 and the conveying pipeline 121 are provided with a blocking assembly 18, the end of the mold assembly 16 is provided with a pipe sleeve 17, the inside of the base 1 is provided with a cooler, and the pipe sleeve 17 and the cooler are provided with a corrugated pipe 170; The flow sensor 122 is used to judge the filling state in the mold assembly 16, when the mold assembly 16 is full, the flow sensor 122 is inducted to control the cooler and the blocking assembly 18 to work, and the extrusion device 12 is stopped to injection.
[0025] The base 1 provides support for the whole device, and after starting, the guide assembly 13 provides stable guidance for the movement of the compression molding assembly 15. The first cylinder 14 drives the compression molding assembly 15 to act, and the mold assembly 16 completes the mold closing. After the mold is closed, the extrusion device 12 transports the molten plastic to the mold assembly 16 through the injection head 120 at the end of the delivery pipeline 121. At this time, the flow sensor 122 between the delivery pipeline 121 and the injection head 120 monitors the plastic flow state in real time to determine the filling condition inside the mold assembly 16. When the mold assembly 16 is filled with plastic, the flow sensor 122 sends a sensing signal to control the extrusion device 12 to stop injection, and at the same time, trigger the blocking assembly 18 to act to block the communication between the delivery pipeline 121 and the mold assembly 16, and start the cooler inside the base 1. The cooling liquid is transported to the mold through the corrugated pipe 170 and the pipe sleeve 17 at the end of the mold assembly 16 for targeted cooling of the molded plastic parts. During the whole process, all components are linked through the signal of the flow sensor 122 to realize the automatic collaborative work from mold closing, injection, filling monitoring to stopping injection, blocking protection and cooling.
[0026] For the judgment of the flow sensor 122, according to the flow of the molten plastic pushed by the extrusion device 12 along the delivery pipeline 121 under the action of pressure at the beginning of injection, the flow sensor 122 can detect a stable flow signal, such as flow rate and flow value remaining in a certain range. This is because the mold cavity has not been filled, and the plastic continues to enter the cavity, and the medium always flows in the pipeline. When the mold cavity is completely filled, the plastic cannot continue to advance, and the plastic flow in the delivery pipeline 121 will stop or the flow rate will suddenly decrease. At this time, the flow sensor 122 senses the mutation of the flow signal, such as from a stable value to zero or a very small value, and converts this change into an electrical signal to the control system, thereby determining that the mold inside has been filled.
[0027] In implementation, referring to Figure 2 As shown in the figure, the guide assembly 13 includes a fixed mold plate 130 and a back mold plate 132. The fixed mold plate 130 and the back mold plate 132 are fixedly connected to the top of the base 1. The four corners of the fixed mold plate 130 and the back mold plate 132 are provided with guide columns 131. The back mold plate 132 is internally provided with a first cylinder 14. The outer walls of the four guide columns 131 and the end of the first cylinder 14 are provided with a compression molding assembly 15.
[0028] The fixed mold plate 130 and the back mold plate 132 serve as a fixed base, and the guide columns 131 between the four corners of the two form a stable guide frame. The first cylinder 14 inside the back mold plate 132 provides power for the compression molding assembly 15. When the first cylinder 14 is started, its output end pushes the compression molding assembly 15 to slide along the outer walls of the four guide columns 131. The guide columns 131 ensure that the movement of the compression molding assembly 15 is stable and avoids deviation, providing rigid support and directional constraint for the movement of the compression molding assembly 15.
[0029] Referring to Figure 5 As shown, the compression molding assembly 15 includes a movable mold plate 150 and a compression plate 152, both of which are movably connected between the four guide columns 131. The movable mold plate 150 is fixedly connected to the end of the first air cylinder 14. The movable mold plate 150 and the compression plate 152 are fixedly connected by a spring 151. The side of the movable mold plate 150 facing the compression plate 152 is provided with a plurality of pressure sensors 153.
[0030] When the first air cylinder 14 is started, the end thereof pushes the movable mold plate 150 to move. The movable mold plate 150 drives the compression plate 152 to move synchronously through the spring 151. The elastic force of the spring 151 makes the compression plate 152 drive the lower mold 161 and the upper mold 160 of the mold assembly 16 to be precisely pre-assembled, so as to avoid misalignment when the molds are closed. At this time, as the movable mold plate 150 continues to move, the spring 151 is gradually compressed, and the rebound force generated thereby promotes the compression plate 152 to apply a continuous and uniform extrusion force to the mold assembly 16, so as to ensure the sealing effect after the molds are closed. When the movable mold plate 150 moves to be in close contact with the compression plate 152, the pressure sensors 153 on the outer wall of the movable mold plate 150 are triggered. At this time, the pressure sensors 153 send signals, indicating that the mold assembly 16 has been tightly closed and is ready for use, so that the subsequent injection molding process can be started. In this way, the precision and sealing performance of the closed molds are ensured, and the mold state is accurately judged through the pressure sensors 153, thereby providing protection for the stable operation of the injection molding process.
[0031] Referring to Figure 6 As shown, the compression plate 152 and the fixed mold plate 130 are provided with the mold assembly 16 therebetween. The mold assembly 16 includes an upper mold 160 and a lower mold 161. The upper mold 160 and the lower mold 161 are provided with a car handle groove therebetween. The lower mold 161 is fixedly connected with a clamping rod 162 at the top thereof. The clamping rod 162 is movably clamped in the inner portion of the upper mold 160.
[0032] The upper mold 160 is arranged on the outer wall of the fixed mold plate 130, and the lower mold 161 is arranged on the outer wall of the compression plate 152. The outer walls of the upper mold 160 and the lower mold 161 are fixedly connected with a slide rod 163 and a support plate 164.
[0033] Figure 5 With Figure 7 The outer walls of the fixed mold plate 130 and the compression plate 152 are provided with a plurality of T-shaped sliding grooves and a plurality of holes. The slide rod 163 is T-shaped. The inner portion of the support plate 164 is provided with a plurality of long holes. The slide rod 163 of the upper mold 160 is slidably connected in the sliding groove of the fixed mold plate 130. The slide rod 163 of the lower mold 161 is slidably connected in the sliding groove of the compression plate 152. The long holes of the support plate 164 of the upper mold 160 are aligned with the holes of the fixed mold plate 130 and are fixed by screws. The long holes of the support plate 164 of the lower mold 161 are aligned with the holes of the compression plate 152 and are fixed by screws.
[0034] The T-shaped slide rod 163 of the outer wall of the upper die 160 and the lower die 161 is respectively slidably connected in the T-shaped slide groove of the fixed mold plate 130 and the pressing plate 152, and the position accuracy of the upper die 160 and the lower die 161 during installation is ensured through the guiding effect of the slide groove and the slide rod 163; after sliding into position, the long hole of the supporting plate 164 of the upper die 160 and the lower die 161 is respectively aligned with the hole of the fixed mold plate 130 and the pressing plate 152, and then fixed through a screw, thereby realizing stable installation of the mold assembly 16. The upper die 160 is fixed to the outer wall of the fixed mold plate 130, and the lower die 161 moves with the pressing plate 152, and when the two are combined, an automobile handle groove matched with the automobile auxiliary handle cover plate is formed; the clamping rod 162 at the top of the lower die 161 is movably clamped in the inside of the upper die 160, and when the mold is combined, precise positioning is realized through the cooperation of the clamping rod 162 and the clamping groove, thereby avoiding the dislocation of the cavity affecting the product forming.
[0035] Referring to Figure 7 As shown in the figure, the fixed mold plate 130 is internally provided with a blocking assembly 18, and the blocking assembly 18 comprises a baffle 180, and the bottom of the baffle 180 is fixedly connected with a No. 2 air cylinder 181.
[0036] The baffle 180 is located between the conveying pipeline 121 and the mold assembly 16, the baffle 180 is internally provided with a circular hole, and the baffle 180 is made of rock wool board material.
[0037] Before injection molding, the No. 2 air cylinder 181 drives the baffle 180 to be in an open state, at this time, the circular hole in the baffle 180 is aligned with the feeding port of the conveying pipeline 121 and the mold assembly 16, thereby ensuring that the molten plastic can smoothly flow from the conveying pipeline 121 into the cavity of the mold assembly 16; when the flow sensor 122 detects that the inside of the mold assembly 16 is full of plastic, the No. 2 air cylinder 181 will be triggered to move, and the No. 2 air cylinder 181 drives the baffle 180 to move, so that the circular hole deviates from the alignment position, thereby blocking the passage between the conveying pipeline 121 and the mold assembly 16.
[0038] Because the baffle 180 is made of rock wool board material, its good heat insulation performance can reduce the influence of the cooling effect of the mold assembly 16 on the plastic in the conveying pipeline 121, thereby avoiding the solidification of the end of the injection liquid in the conveying pipeline 121 due to temperature change; the timely blocking of the passage after the completion of injection molding is realized, thereby preventing the end from being solidified due to backflow or cooling of the plastic, and the stability of the plastic in the conveying pipeline 121 is ensured by the characteristics of the rock wool board, thereby laying a foundation for the subsequent injection molding process.
[0039] In addition, the corrugated pipe 170 is a telescopic structure, the corrugated pipe 170 is connected with the pipe sleeve 17 through threads, and the corrugated pipe 170 is fixedly connected with the water outlet of the cooler.
[0040] One end of the bellows 170 is fixedly connected with the water outlet of the cooler, and the other end is connected with the pipe sleeve 17 at the end of the mold assembly 16 through threads; when the mold assembly 16 is closed or opened, the movement of the lower mold 161 driven by the pressing plate 152 will change the position of the pipe sleeve 17, at this time the bellows 170 can adapt to the displacement of the pipe sleeve 17 through its own stretchable characteristics, ensuring that the cooling pipeline always remains connected without breaking or falling off; while ensuring the sealing performance between the bellows 170 and the pipe sleeve 17, the threaded connection facilitates the subsequent disassembly, maintenance and replacement of the bellows 170. After the cooler is started, the cooling liquid is smoothly transported from the cooler to the pipe sleeve 17 through the bellows 170, and then enters the inside of the mold assembly 16, providing timely cooling for the plastic parts after injection molding.
[0041] Referring to Figure 2 As shown, the base 1 is internally provided with a collection pool 11, which is located below the mold assembly 16, and the inner wall of the collection pool 11 is made of sponge material.
[0042] Since the mold assembly 16 is divided into an upper mold 160 and a lower mold 161, after injection molding, the lower mold 161 is moved away by the pressing plate 152, at this time the formed auxiliary handle cover plate for vehicles falls by gravity due to the loss of support of the lower mold 161 and directly falls into the collection pool 11 below; compared with the prior art which needs to rely on additional demolding mechanisms such as ejector pins or suction cups, this design of self-demolding by gravity simplifies the demolding process and reduces the risk of damage to the surface of the plastic parts caused by mechanical intervention; at the same time, the sponge material used for the inner wall of the collection pool 11 cushions the falling plastic parts, avoiding defects such as scratches and deformation caused by impact, and ensuring the appearance of the product.
[0043] Working principle: First, the upper mold 160 and the lower mold 161 are respectively slid into the sliding grooves of the fixed mold plate 130 and the pressing plate 152 through the T-shaped sliding rods 163, and are fixed after the support plates 164, thereby completing the assembly, and the clamping rod 162 at the top of the lower mold 161 is matched with the clamping groove of the upper mold 160, thereby providing a precise positioning basis for subsequent mold closing.
[0044] Subsequently, the movable mold plate 150 is driven to slide along the guide column 131 by the first air cylinder 14, the pressing plate 152 is synchronously moved by the spring 151, the lower mold 161 and the upper mold 160 are pre-assembled by the elastic force of the spring 151, thereby avoiding misalignment during mold closing; as the movable mold plate 150 continues to advance, the spring 151 is compressed to generate uniform and continuous extrusion force, thereby ensuring the sealing of the mold; when the movable mold plate 150 and the pressing plate 152 are attached to trigger the pressure sensor 153 on the movable mold plate 150, the mold closing is completed, and the equipment enters the injection-ready state.
[0045] Subsequently, the injection molding process is started, the extruding device 12 delivers the molten plastic through the delivery pipe 121 to the mold cavity via the injection head 120, at this time, the flow sensor 122 between the delivery pipe 121 and the injection head 120 monitors the plastic flow state in real time, and the plastic enters the mold through the round hole of the baffle 180 in the blocking assembly 18, fills the automobile handle groove formed by the upper mold 160 and the lower mold 161.
[0046] When the mold cavity is filled with plastic, the flow sensor 122 detects the change in the flow state and sends a signal, and the extruding device 12 immediately stops injection molding; at the same time, the No. 2 cylinder 181 of the blocking assembly 18 drives the baffle 180 to move, so that the round hole deviates from the channel, blocking the communication between the delivery pipe 121 and the mold, and the baffle 180 made of rock wool can reduce the influence of mold cooling on the plastic in the pipe and prevent the end from solidifying; at the same time, the cooler is started synchronously, and the cooling liquid enters the mold through the corrugated pipe 170 and the pipe sleeve 17 to cool the plastic part, and the expansion and contraction characteristics of the corrugated pipe 170 adapt to the movement of the mold to ensure that the cooling passage is unobstructed.
[0047] When the cooling is completed, the lower mold 161 is moved away by the pressing plate 152, and the formed plastic part falls by gravity due to the loss of support and falls into the collection pool 11 below; the sponge material on the inner wall of the collection pool 11 forms a buffer for the falling plastic part to avoid impact damage, and the entire production process is finally completed.
