Description

Technical field:

[0001] The invention relates to the technical field of automobile parts injection molding, in particular to an automobile parts injection molding mold with controllable flow. Background technology:

[0002] Injection molding is also called injection molding. It is a molding method that combines injection and molding. Injection molding is suitable for mass production and complex-shaped products. This method is suitable for mass production of complex-shaped parts and is one of the important processing methods. When making automotive parts, the raw materials are stirred under high temperature, and the molten plastic material is injected into the mold cavity under high pressure during the conveying process. After cooling and solidification, the molded product is obtained.

[0003] Since different auto parts are made in different sizes, it is necessary to control the amount of material when injecting the molten plastic material into the mold cavity. However, the top of the existing mold is directly connected to the discharge pipe, and there is no control device to control the flow of material into the mold cavity, which may cause too much material in the mold. When the residual material cools at the discharge pipe, it may block the discharge pipe, which will have an adverse effect on the quality of the injection molded product and cause material waste. Therefore, in order to solve the above problems, we need to design an auto parts injection mold with controllable flow. Summary of the invention:

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention optimizes an existing flow-controllable automobile parts injection mold. Since the amount of material cannot be controlled when adding material for the first time, when the staff adds the material required for injection molding to the feed port, the motor works in the forward direction, so that the stirring component can stir in the stirring drum. At the same time, the connecting component drives the lifting component to rotate through the driving component, so that the valve component can be controlled to open, so that the material in the stirring drum is discharged into the injection mold; when the motor works in the forward direction, the screw rod is driven to rotate, so that the lifting plate is lowered. The plug can be made to leave the through hole, so that the material moves from the through hole of the filter plate to the discharge box, and the material can be added to the injection mold. Furthermore, when the motor causes the lifting plate to descend, the motor stops working, which is convenient for adding material to the injection mold. After the injection mold is injected for the first time, excess material will accumulate in the discharge box. At this time, the scraper is driven upward by the floating tube in the movable component, so that the scraper can contact the trigger component, drive the control component to move in the valve component, so that the valve component can be The material is then closed, thereby preventing further addition of material; at this time, after the ultrasonic level meter detects that the material has stopped discharging, the motor is made to work in the forward direction, driving the screw rod to continue rotating, so that the lifting plate can rise, thereby causing the plug to contact the through hole, and then closing the discharge port to prevent further addition of material into the injection mold; further, when the lifting plate moves up to the highest point, the motor works in the reverse direction, and through the limit assembly, prevents the lifting assembly from continuing to work and affecting subsequent operations; when the motor works in the reverse direction, the driving assembly drives the rotating assembly to rotate, so that The extraction component is operated to facilitate the extraction of residual materials in the discharge box into the mixing drum, and the materials are stirred by the stirring component to mix them, thereby preventing the materials from cooling and affecting the injection molding work. Furthermore, when the materials are extracted from the discharge box back to the mixing drum, the materials will continue to move downward, thereby causing the movable component to move downward, driving the trigger component to move, so that the residual materials in the discharge box can be discharged into the discharge box for easy recycling. At the same time, when the floating tube moves downward, it drives the scraper to move downward, so that the scraper can clean the inner wall of the discharge box for easy recycling.

[0044] Example 1

[0045] See also Figure 1-Figure 16 , a flow controllable automobile parts injection mold shown in the figure includes a feeding mechanism 100, an injection mold 101, a discharge box 103 is fixedly connected to the top of the injection mold 101, a mixing drum 102 is arranged on the discharge box 103, a top plate 104 is fixedly connected to the top of the mixing drum 102, a motor assembly 110 is arranged on the top plate 104, a mixing drum 102 is arranged in a stirring assembly 120, a driving assembly 130 is arranged on the motor assembly 110, a limiting assembly 140 is arranged on one side of the driving assembly 130, a connecting assembly 150 is arranged on the limiting assembly 140, and a lifting assembly 160 is arranged on the connecting assembly 150; a control mechanism 200, including a valve assembly 210, the valve assembly 210 is located in the inner cavity of the discharge box 103, a movable assembly 220 is arranged in the discharge box 103, a trigger assembly 230 is arranged in the discharge box 103, and a control assembly 240 is arranged on the trigger assembly 230; a cleaning mechanism 300, including a first pipe 301, one side of the first pipe 301 is fixedly connected to the discharge box 103, the other side of the discharge box 103 is provided with an extraction assembly 320, the other side of the drive assembly 130 is provided with a rotating assembly 310, and a second pipe 302 is arranged on the mixing drum 102, and the other side of the second pipe 302 is fixedly connected to the other side of the extraction assembly 320.

[0046] In this embodiment, the specific use process is as follows: when the material is added to the mixing drum 102, the motor assembly 110 works in the forward direction to make the driving assembly 130 work, and the limit assembly 140 is used to make the connecting assembly 150 drive the lifting assembly 160 to work, so that the valve assembly 210 can be lifted and lowered, so that the valve assembly 120 can be controlled to open, so as to facilitate the injection of the material in the mixing drum 102 into the injection mold 101 through the discharge box 103; when the motor assembly 110 drives the lifting assembly 160 to work and makes the valve assembly 120 drop to the lowest point, the motor assembly 110 stops working, so that the device can inject the material into the injection mold 101;

[0047] Since the amount of material cannot be controlled when the device adds material for the first time, when the material is injected, there will be excessive material accumulated in the discharge box 103, which will drive the movable component 220 to move upward, so that the movable component 220 contacts the trigger component 230, and drive the control component 240 to move in the valve component 210, so that the valve component 210 can be initially closed to stop the material discharge and injection; at this time, the motor component 110 works forward, so that the lifting component 160 drives the valve component 210 to rise to the highest point, so that the valve component 210 is completely closed to prevent continuous discharge of materials;

[0048] When the lifting assembly 160 drives the valve assembly 210 to move upward, and the motor assembly 110 works in the reverse direction, the driving assembly 130 drives the rotating assembly 310 to rotate, so that the extraction assembly 320 can work, so that the residual material in the discharge box 103 can be recovered into the mixing drum 102. At this time, the limit assembly 140 can prevent the connection assembly 150 from driving the lifting assembly 160 to work, thereby avoiding the valve assembly 210 from lifting and lowering, which affects the recycling of materials. At the same time, the motor assembly 110 drives the stirring assembly 120 to rotate, so that the recycled materials can be stirred and mixed, and the recycled materials can be prevented from cooling and affecting the injection molding.

[0049] When the material moves downward in the discharge box 103, the movable component 220 will also move downward, so that the trigger component 230 can drive the control component 240 to move, so as to discharge the residual material in the valve component 210 for recycling. At the same time, by moving the movable component 220 downward, the side wall of the discharge box 103 can be cleaned to avoid residual material adhering to the side wall of the discharge box 103 and affecting material recovery; after the material is recovered, the discharge amount during the first material injection can be used to control the flow rate of the material to avoid too much material in the mold, resulting in too much residual material in the discharge box 103, which has an adverse effect on the injection molding of the device.

[0066] In this embodiment, when the material is needed to be injected into the injection mold 101, the motor 110a works in the forward direction, and through the first conveyor belt 130b, it can drive the first connecting roller 130d to rotate, so that the inner ratchet 130f rotates, so that the outer ratchet 140b can drive the second connecting roller 140g to rotate, so that the rotating shaft 150b rotates, and drives the third connecting roller 150f to rotate, and then the third conveyor belt 160b can drive the screw rod 160d to rotate, so that the lifting plate 210c can be lowered, and the plug 210d can be separated from the through hole 102d, so that the material moves from the through hole 102 to the discharge box 210a, and the material is discharged from the discharge trough 210f, so that the material is injected into the injection mold 101. When the lifting plate 210c moves down to the lowest point, the motor 110a stops working, which is convenient for the material to be discharged;

[0067] After injection molding, when residual materials are continuously accumulated in the discharge box 103, the scraper 220b is driven upward by the floating tube 220a, so that the scraper 220b contacts the trigger block 230a, and the trigger block 230a can be moved toward the inside of the trigger groove 103d, driving the second joint 230d to move, so that the second joint 230d can pull the pull block 240a to move, so that the movable rod 240d drives the blocking plate 240b to move, so that the channel on the blocking plate 240b contacts the plugging block 210e, so as to facilitate blocking the channel on the blocking plate 240b, and prevent the material from continuing to be discharged downward, affecting the injection molding;

[0068] When the material in the mixing drum 102 stops being discharged, the motor 110a works forward to drive the first connecting roller 130d to rotate, so that the inner ratchet 130f rotates, so that the outer ratchet 140b drives the second connecting roller 140g to rotate, so that the rotating shaft 150b rotates, drives the third connecting roller 150f to rotate, and then drives the screw rod 160d to rotate through the third conveyor belt 160b, so that the lifting plate 210c can move up, so that the plug 210d on the lifting plate 210c contacts the through hole 102d, and discharges part of the cooled material particles in the through hole 102d, so as to avoid the filter plate 102a being blocked during subsequent use, which affects the subsequent injection molding work. Furthermore, through the fitting of the plug 210d with the through hole 102d, some materials will remain in the discharge box 210a;

[0069] When the device draws the material back into the mixing drum 102 through the extraction component 320, the float tube 220a drives the scraper 220b to move downward, thereby cleaning the inner wall of the discharge box 103 through the scraper 220b to prevent residual material from cooling in the discharge box 103 and adversely affecting the injection molding work of the injection mold; further, when the float tube 220a drives the scraper 220b to move downward, leaving the trigger block 230a, the trigger block 230a can be returned to its original position through the action of the third spring 230b, and the buffer plate 240c can be driven back to its original position through the fourth spring 240e, so that the blocking plate 240b can be separated from the blocking block 210e, so as to facilitate the discharge of the material in the discharge box 210a and facilitate recycling.
