Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing technology, and in particular to an injection mold for an automotive mirror part. Background Technology

[0002] The vanity mirror on the sun visor of a car is mainly used inside the car. During the production process, the accessories around the vanity mirror need to be injection molded. After production, they are installed between the vanity mirror and the car interior.

[0003] After injection molding, existing injection molds for automotive mirror parts may experience issues when ejecting the material from the injection mold groove due to the external component structure of the product itself. This requires additional checks by staff and affects production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an injection mold for automotive mirror parts, which overcomes the deficiencies of existing technologies. It aims to solve the problem that, after injection molding, existing injection molds for automotive mirror parts may experience uneven material ejection from the injection mold due to the external component structure of the item itself, requiring additional inspection by staff and affecting production efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: an injection mold for automotive mirror parts, including a movable mold plate, the movable mold plate including a groove plate and a backing plate, a fixed mold plate provided on the front of the movable mold plate, a main mold frame provided on the back of the movable mold plate, a connecting plate provided between the main mold frame and the movable mold plate, two sets of movable mold grooves opened on one side of the groove plate, and a fixed mold groove corresponding to the movable mold grooves opened on one side of the fixed mold plate, both sets of movable mold grooves having circular holes inside, and a top mold mechanism provided inside each circular hole, the top mold mechanism including a threaded rod and two sets of ejector rods, one end of the threaded rod being rotatably connected to the inside of the groove plate, the other... The end of the rod passes through the pad, the connecting plate, and the main mold frame, and is threadedly connected to the connecting plate. Springs are provided on the outside of both sets of threaded rods. One end of each spring is fixedly connected to one side of the groove plate, and the other end passes through the pad and is fixedly connected to one side of the connecting plate. A pressing mechanism is provided on both sides of the groove plate and the fixed mold plate. The pressing mechanism includes a fixed plate. A transverse sliding groove and a pressing rod are provided inside the fixed plate. An upper inclined plate and a bottom inclined plate are slidably connected to the outside of the fixed plate. One side of the upper inclined plate passes through the transverse sliding groove and is fixedly connected to the fixed mold plate. A pressing rod is provided on one side of the bottom inclined plate through the longitudinal sliding groove.

[0006] By adopting the above technical solution and setting a moving mold plate, after injection molding is completed, the groove plate can be moved backward by rotating the threaded rod. During the movement, the ejector rod will push the injection-molded item out of the moving mold groove. As the groove plate and the fixed mold plate separate, the upper inclined plate will slide along the transverse groove on one side of the fixed plate. During the continuous movement, the bottom inclined plate will move downward, thereby moving the lower pressure rod downward, so that the lower pressure rod reaches between the groove plate and the fixed mold plate. This setting can prevent the material from getting stuck at one end of the ejector rod during ejection. The falling of the lower pressure rod will generate an upward force on the item, causing the item to fall from one end of the ejector rod. This can effectively prevent the material from accumulating between the moving mold plate and the fixed mold plate and affecting the next injection molding. Moreover, when the fixed mold plate and the groove plate approach and close together, the upper inclined plate will return to the bottom of the bottom inclined plate and raise the lower pressure rod again. No corresponding operation is required from the operator, which effectively improves work efficiency.

[0007] As a preferred technical solution of this application, the interior of the trough plate is provided with two sets of cooling water troughs and multiple sets of flow channels. The multiple sets of flow channels are arranged intersectingly and are located between the two sets of cooling water troughs. Both sets of cooling water troughs are interconnected with the multiple sets of flow channels. Multiple sets of water inlets and outlets are provided around the trough plate, and the multiple sets of water inlets and outlets are connected to the interior of the cooling water troughs or flow channels.

[0008] By adopting the above technical solution and setting up cooling water tanks and flow channels, heat dissipation of injection molded materials can be achieved quickly during use. Compared with simple heat pipe heat dissipation, the area is larger. The multiple sets of inlet and outlet ports allow operators to easily adjust the inlet and outlet of the coolant inside the tank plate according to the shape of the injection molded item, further improving practicality.

[0009] As a preferred technical solution of this application, each of the two sets of push rods is provided with a push head on one side, and the size of the two sets of push heads matches the size and dimensions of the circular hole.

[0010] By adopting the above technical solution and setting the ejector head, the contact area between the ejector rod and the material can be increased during use, thereby improving the ejection effect. At the same time, the size and dimensions of the 303 and the round hole are matched to make the connection tighter and improve the sealing of the mold.

[0011] As a preferred technical solution of this application, the pad is provided with multiple sets of stabilizing rods on the side near the connecting plate, and the other end of each set of stabilizing rods passes through the connecting plate and the main mold frame and is slidably connected to the connecting plate and the main mold frame.

[0012] By adopting the above technical solution and setting a stabilizing bar, the stability of the mold during movement can be improved, preventing deviation and enhancing the practicality of the device.

[0013] As a preferred technical solution of this application, a fitting groove is provided on one side of the groove plate, the fitting groove is located around the moving mold groove, and a fitting block corresponding to the fitting groove is provided on one side of the fixed mold plate.

[0014] By adopting the above technical solution and setting the interlocking block, the fitting effect between the moving mold groove and the fixed mold groove can be further improved during use, thereby further enhancing the sealing performance.

[0015] As a preferred technical solution of this application, both sets of fixed mold slots are provided with injection holes, the fixed mold plate is provided with a flow groove, and the flow groove is interconnected with the two sets of injection holes.

[0016] By adopting the above technical solution and setting up a flow channel, the plastic material can be quickly and evenly introduced into the two sets of fixed mold slots after entering the flow channel, thus achieving uniformity in injection molding between the two sets of fixed mold slots.

[0017] As a preferred technical solution of this application, the bottom of the groove plate is provided with two sets of stabilizing bars, and the other side of the two sets of stabilizing bars is slidably connected to the bottom of the fixed template.

[0018] By adopting the above technical solution and setting a stabilizing bar, the stability of the movement between the moving template and the fixed template can be further improved during use, and the offset phenomenon that may be caused by long-term use can be further reduced.

[0019] As a preferred technical solution of this application, the top of the moving template is provided with two sets of ventilation holes, and both sets of ventilation holes are interconnected with the moving template groove.

[0020] By adopting the above technical solution and setting vent holes, the top of the moving mold groove can be quickly vented. Located at the top of the groove plate, it can effectively reduce the burning phenomenon caused by air bubbles inside and reduce the probability of defects.

[0021] The beneficial effects of this application are:

[0022] 1. By setting a moving mold plate, after injection molding, the groove plate can be moved backward by rotating the threaded rod. During the movement, the ejector rod will push the molded item out of the moving mold groove. As the groove plate and the fixed mold plate separate, the upper inclined plate will slide along the transverse groove on one side of the fixed plate. During the continuous movement, the bottom inclined plate will move downward, which will cause the lower pressure rod to move downward, so that the lower pressure rod reaches between the groove plate and the fixed mold plate. This setting can prevent the material from getting stuck at one end of the ejector rod during ejection. The falling of the lower pressure rod will generate an upward force on the item, causing the item to fall from one end of the ejector rod. This can effectively prevent the material from accumulating between the moving mold plate and the fixed mold plate and affecting the next injection molding. When the fixed mold plate and the groove plate come close together and close, the upper inclined plate will return to the bottom of the bottom inclined plate and raise the lower pressure rod again. No manual operation is required, which can effectively improve work efficiency.

[0023] 2. By setting up cooling water tanks and flow channels, heat dissipation of injection molded materials can be completed quickly during use. Compared with simple heat pipe heat dissipation, the area is larger. The multiple sets of inlet and outlet ports allow operators to easily adjust the inlet and outlet of the coolant inside the tank plate according to the shape of the injection molded item, further improving practicality.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Reference Figures 1-5 An injection mold for an automotive mirror part includes a movable mold plate 1, which includes a groove plate 101 and a pad plate 102. A fixed mold plate 2 is provided on the front of the movable mold plate 1, and a main mold frame 4 is provided on the back of the movable mold plate 1. A connecting plate 401 is provided between the main mold frame 4 and the movable mold plate 1. Two sets of movable mold grooves 103 are opened on one side of the groove plate 101, and a fixed mold groove 201 corresponding to the movable mold grooves 103 is opened on one side of the fixed mold plate 2. Circular holes 104 are opened inside the two sets of movable mold grooves 103, and ejector mechanisms 3 are provided inside the circular holes 104. Ejector mechanisms 3 include threaded rods 301 and two sets of ejector rods 302. One end of the threaded rod 301 is rotatably connected to the inside of the groove plate 101, and the other end passes through the pad plate 102 and the connecting plate 4. The mold base 4 and the main mold frame 4 are threadedly connected to the connecting plate 401. Springs 304 are provided on the outside of both sets of threaded rods 301. One end of the spring 304 is fixedly connected to one side of the groove plate 101, and the other end passes through the pad plate 102 and is fixedly connected to one side of the connecting plate 401. A pressing mechanism 6 is provided on both sides of the groove plate 101 and the fixed template 2. The pressing mechanism 6 includes a fixed plate 601. A transverse sliding groove 602 and a pressing rod 606 are provided inside the fixed plate 601. An upper inclined plate 603 and a bottom inclined plate 604 are slidably connected to the outside of the fixed plate 601. One side of the upper inclined plate 603 passes through the transverse sliding groove 602 and is fixedly connected to the fixed template 2. One side of the bottom inclined plate 604 passes through the longitudinal sliding groove 605 and is provided with the pressing rod 606. A top head 303 is provided on one side of each set of top rods 302. The size of both top heads 303 matches the size and dimensions of the circular hole 104.

[0032] By setting the moving mold plate 1, during use, after injection molding, the threaded rod 301 can be rotated to move the groove plate 101 backward. During the movement, the ejector rod 302 will push the molded item out of the moving mold groove 103. As the groove plate 101 and the fixed mold plate 2 disengage, the upper inclined plate 603 will slide along the transverse slide groove 602 on one side of the fixed plate 601. During the continuous movement, the bottom inclined plate 604 will move downward, thereby causing the lower pressure rod 606 to move downward, so that the lower pressure rod 606 reaches the groove plate 101 and the fixed mold. The arrangement between plates 2 prevents material from getting caught on one end of the ejector rod 302 during ejection. The falling of the lower pressure rod 606 exerts a force from above on the material, causing it to fall from one end of the ejector rod 302. This effectively prevents material from accumulating between the moving mold plate 1 and the fixed mold plate 2, thus avoiding interference with subsequent injection molding. Furthermore, when the fixed mold plate 2 and the groove plate 101 subsequently close together, the upper inclined plate 603 returns to the bottom of the lower inclined plate 604, re-lifting the lower pressure rod 606 without requiring manual intervention, significantly improving work efficiency. The ejector head 303 increases the contact area between the ejector rod 302 and the material, enhancing the ejection effect. Simultaneously, the matching size and dimensions of 303 and the circular hole 104 ensure a tighter connection, improving the mold's sealing.

[0033] Reference Figure 1The trough plate 101 has two sets of cooling water troughs 106 and multiple sets of flow channels 107 inside. The multiple sets of flow channels 107 are arranged intersectingly and are located between the two sets of cooling water troughs 106. Both sets of cooling water troughs 106 are interconnected with the multiple sets of flow channels 107. Multiple sets of inlet and outlet water ports 108 are arranged around the trough plate 101, and the multiple sets of inlet and outlet water ports 108 are connected to the interior of the cooling water troughs 106 or the flow channels 107. The pad plate 102 has multiple sets of stabilizing rods 5 on the side near the connecting plate 401. The other end of the multiple sets of stabilizing rods 5 passes through the connecting plate 401 and the main mold frame 4 and is slidably connected to the connecting plate 401 and the main mold frame 4. The two sets of fixed mold slots 201 are provided with injection holes 202 inside. The fixed mold plate 2 is provided with a flow channel 204 inside. 204 is interconnected with the two sets of injection holes 202; by setting the cooling water tank 106 and the flow channel 107, the heat dissipation effect of the injection molded material can be quickly completed during use, and the heat dissipation area is larger than that of a simple heat pipe. The multiple sets of inlet and outlet ports 108 can make it convenient for the operator to adjust the inlet and outlet of the coolant inside the tank plate 101 according to the shape of the injection molded item, further improving the practicality; by setting the stabilizing rod 5, the stability of the mold during use can be improved, preventing the phenomenon of deviation, and improving the practicality of the device; by setting the flow channel 204, the plastic material can quickly and evenly enter the interior of the two sets of fixed mold slots 201 after entering the flow channel 204, realizing the uniformity of injection between the two sets of fixed mold slots 201.

[0034] Reference Figure 1 A fitting groove 105 is provided on one side of the groove plate 101. The fitting groove 105 is located around the moving mold groove 103, and a fitting block 203 corresponding to the fitting groove 105 is provided on one side of the fixed mold plate 2. By setting the fitting block 203, the fitting effect between the moving mold groove 103 and the fixed mold groove 201 can be further improved during use, and the sealing performance can be further improved. Two sets of stabilizing strips 7 are provided at the bottom of the groove plate 101, and the other side of the two sets of stabilizing strips 7 is slidably connected to the bottom of the fixed mold plate 2. By setting the stabilizing strips 7, the fitting effect between the moving mold groove 103 and the fixed mold groove 201 can be further improved, and the sealing performance can be further improved. The fixed strip 7, during use, can further improve the stability of the movement between the moving template 1 and the fixed template 2, and further reduce the deviation phenomenon that may be caused by long-term use; the top of the moving template 1 is provided with two sets of vent holes 109, both sets of vent holes 109 are interconnected with the moving mold groove 103; by providing vent holes 109, the top of the moving mold groove 103 can be quickly vented, located at the top of the groove plate 101, which can effectively reduce the burning phenomenon caused by air bubbles inside, and reduce the probability of defects.

[0035] Working principle: By setting the moving mold plate 1, after injection molding, the threaded rod 301 can be rotated to move the groove plate 101 backward. During the movement, the ejector rod 302 will push the molded item out of the moving mold groove 103. As the groove plate 101 and the fixed mold plate 2 disengage, the upper inclined plate 603 will slide along the transverse slide groove 602 on one side of the fixed plate 601. During the continuous movement, the bottom inclined plate 604 will move downward, thereby causing the lower pressure rod 606 to move downward, so that the lower pressure rod 606 reaches between the groove plate 101 and the fixed mold plate 2. This setting can prevent the material from getting caught on one end of the ejector rod 302 during ejection. The falling of the lower pressure rod 606 will generate an upward force on the item, causing the item to... The material falls from one end of the top rod 302, which can effectively prevent the material from accumulating between the moving mold plate 1 and the fixed mold plate 2 and affecting the next injection molding. When the fixed mold plate 2 and the groove plate 101 approach and close together, the upper inclined plate 603 will return to the bottom of the lower inclined plate 604 and raise the lower pressure rod 606 again. No corresponding operation is required from the operator, which effectively improves the work efficiency. By setting the cooling water tank 106 and the flow channel 107, the heat dissipation effect of the injection molded material can be completed quickly during use. Compared with the heat pipe heat dissipation, the area is larger. The multiple sets of inlet and outlet ports 108 can make it convenient for the operator to adjust the inlet and outlet of the coolant inside the groove plate 101 according to the shape of the injection molded item, further improving the practicality.

[0036] Among them, by setting the top head 303, the contact area between the top rod 302 and the material can be increased during use, thus improving the material ejection effect. At the same time, the size and dimensions of 303 and the round hole 104 match, making their connection tighter and improving the sealing of the mold. By setting the stabilizing rod 5, the stability of the mold during movement can be improved during use, preventing the phenomenon of displacement and improving the practicality of the device.

[0037] Meanwhile, by setting the fitting block 203, the fitting effect between the moving mold groove 103 and the fixed mold groove 201 can be further improved during use, and the sealing performance can be further improved.

[0038] In addition, by setting the flow channel 204, the plastic material can quickly and evenly enter the two sets of fixed mold grooves 201 after entering the flow channel 204, thus achieving uniformity in injection molding between the two sets of fixed mold grooves 201. By setting the stabilizing strip 7, the stability of the movement between the moving mold plate 1 and the fixed mold plate 2 can be further improved during use, and the deviation phenomenon that may be caused by long-term use can be further reduced. By setting the vent hole 109, the top of the moving mold groove 103 can be quickly vented. Located at the top of the groove plate 101, it can effectively reduce the burning phenomenon caused by air bubbles inside, and reduce the probability of defects.
