Description

Technical Field

[0001] The invention relates to the technical field of automobile lampshade injection molding production, in particular to an automobile lampshade injection molding device with a thickness adjustable function. Background Art

[0002] Car lampshades are mainly parts that protect and beautify the car lights in the car lighting mechanism. Car lampshades can play the role of waterproof, anti-collision, dustproof, etc., effectively extending the life of the car lights and ensuring driving safety. At present, car lampshades are usually produced by injection molding. Since the method of producing car lampshades by injection molding is convenient and fast, and the product quality is high, the injection molding production method is widely used in the production of car lampshades.

[0003] The existing automobile lampshade injection molding device does not have a thickness adjustment function when performing automobile lampshade injection molding, so that the injection molding device can only produce lampshades of a single specification. Injection molding devices of multiple specifications are required, which increases the production cost of the enterprise and affects the efficiency of the enterprise. Summary of the invention

[0004] The object of the present invention is to provide an automobile lampshade injection molding device with adjustable thickness to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an injection molding device for a lampshade of an automobile headlight with an adjustable thickness function, the injection molding device for a lampshade of an automobile headlight with an adjustable thickness function comprises a lower mold base and an upper mold base, two groups of mold guide rails are symmetrically installed on the upper mold base, slide seats are slidably installed on the two groups of the mold guide rails, the two groups of slide seats are connected by a linkage plate, a transmission rod is installed at the bottom of the linkage plate, a sliding cavity is provided in the upper mold base, a mold is slidably installed in the sliding cavity, and a sliding hole is opened at the top of the sliding cavity, the transmission rod passes through the sliding hole and is connected to the mold, when the injection molding thickness needs to be adjusted after the upper mold base and the lower mold base are molded, the mold guide rail is started so that the slide seat can move back and forth longitudinally along the mold guide rail, and the slide seat can drive the linkage plate to move longitudinally, so that the linkage plate can drive the mold to move back and forth longitudinally in the sliding cavity synchronously through the transmission rod, which is conducive to automatically adjusting the distance between the mold and the groove on the lower mold base, and conveniently adjusting the injection molding thickness automatically.

[0006] As a preferred technical solution, a cooling component and a cooling enhancement component are provided on the lower die base, the cooling component cooperates with the movement of the slide base, and the operation of the cooling component is utilized to provide operating driving force for the cooling enhancement component.

[0007] As a preferred technical solution, the cooling assembly includes a cooling chamber, a cooling water tank, a water pump, a water suction pipe, a water delivery pipe and a water return pipe;

[0008] A cooling chamber is provided in the lower mold base, and a cooling water tank is fixedly installed on the lower mold base, a refrigerator is installed in the cooling water tank, and a water pump is installed on the cooling water tank. The input end of the water pump is connected to the output end of the cooling water tank through a suction pipe, the output end of the water pump is connected to one side of the cooling chamber through a water delivery pipe, and the other side of the cooling chamber is connected to the input end of the cooling water tank through a return pipe. When the injection molding is completed and the cooling treatment is performed, the water pump is started so that the water pump can suck the cooling water flow in the cooling water tank through the suction pipe, and then the cooling water is delivered to the cooling chamber of the lower mold base through the water delivery pipe, so as to facilitate the cooling of the injection molded parts by the cooling water. At the same time, after the cooling water flow is injected into the cooling chamber, it can flow back to the cooling water tank through the return pipe, so as to facilitate the refrigerator in the cooling water tank to refrigerate the hot water flow, which is conducive to the recycling of the cooling water flow.

[0009] As a preferred technical solution, an adjusting knob is provided on the water pump, a linkage rod is installed on the linkage plate, and an adjusting tooth plate is installed on the linkage rod. When the upper mold base and the lower mold base are closed, the adjusting tooth plate is meshed with the adjusting knob. When the upper mold base and the lower mold base are closed, the adjusting knob can drive the adjusting tooth plate to keep the running speed of the water pump at the lowest state. When the linkage plate moves up to adjust the injection molding thickness, the linkage plate can drive the adjusting tooth plate to move up accordingly through the linkage rod, and the adjusting tooth plate can drive the adjusting knob to rotate accordingly, so that the adjusting knob can control the water pump to increase the corresponding operating speed.

[0010] As a preferred technical solution, the cooling enhancement component includes a negative pressure box, a piston, a negative pressure tube, a two-way one-way valve, a connecting rod, a perforation, a linkage block, a slide groove, a slider, a connecting spring, a transmission tooth plate and a push-pull plate;

[0011] A negative pressure box is installed on the lower mold base, a piston is slidably installed in the negative pressure box, and two-way one-way valves are arranged on the water supply pipe and the return pipe. The upper part of the negative pressure box is connected to the two-way one-way valve through the negative pressure pipe, and a connecting rod is installed on the piston. A through hole is opened on the top of the negative pressure box, and the connecting rod passes through the through hole and is slidably matched. A linkage block is installed on the upper end of the connecting rod. Two groups of slide grooves are symmetrically opened on the lower mold base, and sliders are slidably installed in the two groups of slide grooves. The sliders are connected to the slide grooves through connecting springs, and a transmission tooth plate is installed on the slider, and the transmission tooth plate is connected to the linkage block through a push-pull plate. When the cooling water flow in the water supply pipe and the return pipe is transported rapidly, a negative pressure effect can be formed in the negative pressure box through the negative pressure pipe, so that the piston can move upward under the action of negative pressure, and the piston can drive the linkage block to move upward synchronously through the connecting rod. Since the slider can move horizontally in the slide groove, at this time, the push-pull plate can push the transmission tooth plate to move horizontally synchronously through the upward movement of the linkage block.

[0012] As an optimal technical solution, the two ends of the push-pull plate are respectively hinged with the transmission gear plate and the linkage block, an electrically controlled pressure relief valve is installed at the bottom of the negative pressure box, and the water pump is electrically connected to the electrically controlled pressure relief valve. When the water pump is running, the electrically controlled pressure relief valve is closed, and when the water pump stops, the electrically controlled pressure relief valve is opened.

[0013] As a preferred technical solution, the cooling enhancement assembly further includes a fixed block, a transmission gear, a rotating column, a rotating plate, a connecting end and an air hole;

[0014] Fixed blocks are symmetrically installed on both sides of the lower mold base, and a rotating shaft is rotatably installed on the fixed block. A transmission gear is installed at one end of the rotating shaft, and the transmission gear is meshed with a transmission tooth plate. A rotating column is installed at the other end of the rotating shaft, and a rotating plate is installed on the rotating column. A connecting end is installed on the rotating plate. An air hole is opened on the upper part of the sliding cavity. When the transmission tooth plate moves laterally, the transmission tooth plate can drive the transmission gear to rotate through the meshing action of the transmission tooth plate and the transmission gear. The rotation of the transmission gear can drive the rotating plate to rotate synchronously through the rotating shaft and the rotating column, so that the connecting end on the rotating plate can be automatically embedded in the air hole.

[0015] As a preferred technical solution, the connecting end is connected to the two-way one-way valve through an air intake pipe. The air intake pipe is a one-way pipe. By utilizing the rapid flow of cooling water in the water supply pipe and the return pipe, a negative pressure can be formed in the sliding cavity through the air intake pipe, which is beneficial to the absorption of hot air flow, thereby accelerating the cooling of the injection molded parts.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] When the injection thickness needs to be adjusted after the upper mold base and the lower mold base are closed, the mold guide rail is started so that the slide can move back and forth longitudinally along the mold guide rail, and the slide can drive the linkage plate to move longitudinally, so that the linkage plate can drive the mold to move back and forth synchronously longitudinally in the slide cavity through the transmission rod, which is beneficial to automatically adjust the distance between the mold and the groove on the lower mold base, and facilitate automatic adjustment of the injection thickness.

[0018] When the injection molding is completed and the cooling process is performed, the water pump is started so that the water pump can suck the cooling water flow in the cooling water tank through the suction pipe, and then the cooling water is transported to the cooling cavity of the lower mold base through the water pipe, so that the cooling water can cool the injection molded parts. At the same time, after the cooling water flow is injected into the cooling cavity, it can flow back to the cooling water tank through the return pipe, so that the refrigerator in the cooling water tank can cool the hot water flow, which is conducive to the recycling of the cooling water flow.

[0019] The negative pressure in the negative pressure box can make the piston move upward, and the transmission tooth plate can be pushed to move horizontally synchronously through the linkage block and the push-pull plate. Through the meshing action of the transmission tooth plate and the transmission gear, the rotating plate can be driven to rotate through the rotating shaft and the rotating column, so that the connecting end on the rotating plate is automatically embedded in the air hole, which makes it convenient for the suction pipe to absorb the hot air flow under the action of negative pressure, thereby accelerating the cooling of the injection molded parts.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example: Figure 1-Figure 5 As shown, the present invention provides the following technical solutions: an automobile lampshade injection molding device with adjustable thickness, the automobile lampshade injection molding device with adjustable thickness comprises a lower mold base 1 and an upper mold base 2, two groups of mold guide rails 3 are symmetrically installed on the upper mold base 2, and slide seats 4 are slidably installed on the two groups of mold guide rails 3, and the two groups of slide seats 4 are connected by a linkage plate 5, and a transmission rod 6 is installed at the bottom of the linkage plate 5, and a sliding cavity 7 is provided in the upper mold base 2, and a mold 9 is slidably installed in the sliding cavity 7, and the sliding cavity 7 has a sliding cavity 7. A sliding hole 8 is provided on the top, and the transmission rod 6 passes through the sliding hole 8 and is connected to the mold 9. When the injection thickness needs to be adjusted after the upper mold base 2 and the lower mold base 1 are molded together, the mold guide rail 3 is started, so that the slide 4 can move back and forth longitudinally along the mold guide rail 3, and the slide 4 can drive the linkage plate 5 to move longitudinally, so that the linkage plate 5 can drive the mold 9 to move synchronously longitudinally in the sliding cavity 7 through the transmission rod 6, which is conducive to automatically adjusting the distance between the mold 9 and the groove on the lower mold base 1, and conveniently adjusting the injection thickness automatically.

[0033] The lower die base 1 is provided with a cooling assembly 10 and a cooling enhancement assembly 11 . The cooling assembly 10 cooperates with the movement of the slide base 4 , and the operation of the cooling assembly 10 provides an operating driving force for the cooling enhancement assembly 11 .

[0034] The cooling assembly 10 includes a cooling chamber 1001, a cooling water tank 1002, a water pump 1003, a water suction pipe 1004, a water delivery pipe 1005 and a water return pipe 1006;

[0035] A cooling cavity 1001 is provided in the lower die base 1, and a cooling water tank 1002 is fixedly installed on the lower die base 1, a refrigerator is installed in the cooling water tank 1002, a water pump 1003 is installed on the cooling water tank 1002, the input end of the water pump 1003 is connected to the output end of the cooling water tank 1002 through a water suction pipe 1004, the output end of the water pump 1003 is connected to one side of the cooling cavity 1001 through a water delivery pipe 1005, and the other side of the cooling cavity 1001 is connected to the input end of the cooling water tank 1002 through a return pipe 1006. When the injection molding is completed and the cooling process is performed, the water pump 1003 is started so that the water pump 1003 can suck the cooling water flow in the cooling water tank 1002 through the water suction pipe 1004, and then the cooling water is transported to the cooling cavity 1001 of the lower mold base 1 through the water delivery pipe 1005, so as to facilitate the cooling water to cool the injection molded parts. At the same time, after the cooling water flow is injected into the cooling cavity 1001, it can flow back to the cooling water tank 1002 through the return pipe 1006, so as to facilitate the refrigerator in the cooling water tank 1002 to cool the hot water flow, which is conducive to the recycling of the cooling water flow.

[0036] The water pump 1003 is provided with an adjusting knob 1007, and a linkage rod 1008 is installed on the linkage plate 5. An adjusting tooth plate 1009 is installed on the linkage rod 1008. When the upper mold base 2 and the lower mold base 1 are molded, the adjusting tooth plate 1009 is meshed with the adjusting knob 1007. After the upper mold base 2 and the lower mold base 1 are molded, the adjusting knob 1007 can drive the operating speed of the water pump 1003 to the lowest state under the drive of the adjusting tooth plate 1009. When the linkage plate 5 moves up to adjust the injection molding thickness, the linkage plate 5 can drive the adjusting tooth plate 1009 to move up accordingly through the linkage rod 1008, and can allow the adjusting tooth plate 1009 to drive the adjusting knob 1007 to rotate accordingly, so that the adjusting knob 1007 can control the water pump 1003 to increase the corresponding operating speed.

[0037] The cooling enhancement component 11 includes a negative pressure box 1101, a piston 1102, a negative pressure tube 1103, a two-way check valve 1104, a connecting rod 1105, a perforation 1106, a linkage block 1107, a slide groove 1108, a slider 1109, a connecting spring 1110, a transmission tooth plate 1111 and a push-pull plate 1112;

[0038] A negative pressure box 1101 is installed on the lower mold base 1, and a piston 1102 is slidably installed in the negative pressure box 1101. A two-way one-way valve 1104 is provided on the water supply pipe 1005 and the return pipe 1006. The upper part of the negative pressure box 1101 is connected to the two-way one-way valve 1104 through a negative pressure pipe 1103. A connecting rod 1105 is installed on the piston 1102. A through hole 1106 is opened on the top of the negative pressure box 1101. The connecting rod 1105 passes through the through hole 1106 and is slidably matched. A linkage block 1107 is installed on the upper end of the connecting rod 1105. Two groups of slide grooves 1108 are symmetrically opened on the lower mold base 1. Slide blocks 1109 are slidably installed in the two groups of slide grooves 1108. 9 is connected to the slide groove 1108 through the connecting spring 1110, and a transmission tooth plate 1111 is installed on the slider 1109. The transmission tooth plate 1111 is connected to the linkage block 1107 through the push-pull plate 1112. When the cooling water in the water supply pipe 1005 and the return pipe 1006 is transported quickly, a negative pressure effect can be formed in the negative pressure box 1101 through the negative pressure pipe 1103, so that the piston 1102 can move upward under the action of the negative pressure, and the piston 1102 can drive the linkage block 1107 to move upward synchronously through the connecting rod 1105. Since the slider 1109 can move horizontally in the slide groove 1108, at this time, the upward movement of the linkage block 1107 can make the push-pull plate 1112 push the transmission tooth plate 1111 to move horizontally synchronously.

[0039] The two ends of the push-pull plate 1112 are hinged to the transmission gear plate 1111 and the linkage block 1107 respectively. An electrically controlled pressure relief valve is installed at the bottom of the negative pressure box 1101. The water pump 1003 is electrically connected to the electrically controlled pressure relief valve. When the water pump 1003 is running, the electrically controlled pressure relief valve is closed. When the water pump 1003 stops running, the electrically controlled pressure relief valve is opened.

[0040] The cooling enhancement assembly 11 further includes a fixing block 1113, a transmission gear 1114, a rotating column 1115, a rotating plate 1116, a connecting end 1117 and an air hole 1118;

[0041] Fixed blocks 1113 are symmetrically installed on both sides of the lower mold base 1, and a rotating shaft is rotatably installed on the fixed block 1113. A transmission gear 1114 is installed at one end of the rotating shaft, and the transmission gear 1114 meshes with a transmission tooth plate 1111. A rotating column 1115 is installed at the other end of the rotating shaft, and a rotating plate 1116 is installed on the rotating column 1115. A connecting terminal 1117 is installed on the rotating plate 1116. An air hole 1118 is opened on the upper part of the sliding cavity 7. When the transmission tooth plate 1111 moves horizontally, the transmission tooth plate 1111 can drive the transmission gear 1114 to rotate through the meshing action of the transmission tooth plate 1111 and the transmission gear 1114. The rotation of the transmission gear 1114 can drive the rotating plate 1116 to rotate synchronously through the rotating shaft and the rotating column 1115, so that the connecting terminal 1117 on the rotating plate 1116 can automatically embed into the air hole 1118.

[0042] The connecting end 1117 is connected to the two-way one-way valve 1104 through the suction pipe 1119. The suction pipe 1119 is a one-way pipe. By utilizing the rapid flow of cooling water in the water supply pipe 1005 and the return pipe 1006, a negative pressure can be formed in the sliding cavity 7 through the suction pipe 1119, which is beneficial to the absorption of hot air flow, thereby accelerating the cooling of the injection molded parts.

[0043] Working principle of the present invention:

[0044] When the injection thickness needs to be adjusted after the upper mold base 2 and the lower mold base 1 are closed, the mold guide rail 3 is started so that the slide 4 can move back and forth longitudinally along the mold guide rail 3, and the slide 4 can drive the linkage plate 5 to move longitudinally, so that the linkage plate 5 can drive the mold 9 to move synchronously longitudinally in the slide cavity 7 through the transmission rod 6, which is conducive to automatically adjusting the distance between the mold 9 and the groove on the lower mold base 1, and conveniently adjusting the injection thickness.

[0045] When the injection molding is completed and the cooling process is performed, the water pump 1003 is started so that the water pump 1003 can suck the cooling water flow in the cooling water tank 1002 through the suction pipe 1004, and then the cooling water is transported to the cooling cavity 1001 of the lower mold base 1 through the water pipe 1005, so as to facilitate the cooling of the injection molded parts by the cooling water. At the same time, after the cooling water flow is injected into the cooling cavity 1001, it can flow back to the cooling water tank 1002 through the return pipe 1006, so as to facilitate the refrigerator in the cooling water tank 1002 to cool the hot water flow, which is conducive to the recycling of the cooling water flow.

[0046] When the upper mold base 2 and the lower mold base 1 are closed, the adjusting knob 1007 can drive the adjusting tooth plate 1009 to make the running speed of the water pump 1003 to the lowest state. When the linkage plate 5 moves up to adjust the injection thickness, the linkage plate 5 can drive the adjusting tooth plate 1009 to move up accordingly through the linkage rod 1008, so that the adjusting tooth plate 1009 can drive the adjusting knob 1007 to rotate accordingly, so that the adjusting knob 1007 can control the water pump 1003 to increase the corresponding running speed.

[0047] When the cooling water in the water supply pipe 1005 and the return pipe 1006 is transported quickly, a negative pressure effect can be formed in the negative pressure box 1101 through the negative pressure pipe 1103, so that the piston 1102 can move upward under the negative pressure, and the piston 1102 can drive the linkage block 1107 to move upward synchronously through the connecting rod 1105. Since the slider 1109 can move horizontally in the slide groove 1108, at this time, the upward movement of the linkage block 1107 can make the push-pull plate 1112 push the transmission gear plate 1111 to move horizontally synchronously. When the plate 1111 moves laterally, the meshing action of the transmission tooth plate 1111 and the transmission gear 1114 can make the transmission tooth plate 1111 drive the transmission gear 1114 to rotate, and the rotation of the transmission gear 1114 can drive the rotating plate 1116 to rotate synchronously through the rotating shaft and the rotating column 1115, so that the connecting end 1117 on the rotating plate 1116 can be automatically embedded in the air hole 1118, so that the suction pipe 1119 is conducive to absorbing the hot air flow under the action of negative pressure, thereby accelerating the cooling of the injection molded parts.
