Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to an injection mold for integrally forming an insert of a plastic liner of a cigarette lighter. Background Art

[0002] With the rapid development of the automobile industry, the quality and performance requirements of cigarette lighters, as a common component inside the car, are constantly improving. In modern manufacturing, the production of plastic liner of cigarette lighter mainly relies on injection molds. Injection molds have the advantages of high quality and high efficiency production. In injection molds, the insert-integrated injection mold can integrate the insert with the mold body, which can effectively improve production efficiency, product quality and mold life. Therefore, we propose an insert-integrated injection mold for the plastic liner of the cigarette lighter.

[0003] The prior art also has the following defects during use:

[0004] 1. When the plastic liner of the cigarette lighter is injected into the mold, the raw material will remain in the flow channel during the injection process. Therefore, the raw material after cooling and forming will solidify in the flow channel, which will lead to the need to cut the raw material formed in the flow channel at a later stage, thus reducing the practicality of the injection mold.

[0005] 2. In the prior art, when the plastic liner of the cigarette lighter is molded with an integrally formed insert, the traditional injection mold has poor pressure control during the injection molding process. As a result, when the injection mold is injecting material, the quality of the product produced may be reduced due to too little or too much pressure, thereby affecting the yield rate of the injection mold.

[0006] In view of this, we propose an integrally formed injection mold for the insert of the plastic liner of the cigarette lighter to solve the existing problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] like Figure 1 - Figure 8 As shown, the one-piece injection mold for inserts of the plastic liner of the cigarette lighter proposed by the present invention comprises a heat-conducting ring 1, a fixing plate 5 and an injection assembly 6. Four fixing bolts 504 are installed inside the fixing plate 5 through a threaded structure, and a sub-plate 503 is installed on the outer side of the fixing bolts 504 through a threaded structure. A mounting seat 505 is fixedly installed on the side of the sub-plate 503 close to the fixing plate 5, and four mounting rods 506 are fixedly installed on the side of the fixing plate 5 away from the sub-plate 503. The fixing plate 5 is used to provide a mounting position for surrounding components. The fixing bolts 504 are used to connect the fixing plate 5 and the sub-plate 503, and fix the device at a specified position to ensure the installation stability of the device. The sub-plate 503 can cooperate with the fixing plate 5 to provide a mounting position for surrounding components. The mounting seat 505 can provide a mounting position for the injection assembly 6 and ensure the stability of the installation of the injection assembly 6. The mounting rod 506 can provide a mounting position for the mounting plate 2.

[0036] The mounting seat 505 is internally fixed with an injection assembly 6, which can quantitatively inject the raw materials used for injection molding, and can prevent the raw materials from remaining inside the flow channel during the injection molding process, thereby reducing the steps of reprocessing the product later, and can also ensure that the pressure inside the mold is stable during the injection molding process, thereby ensuring the processing quality of the mold for the product;

[0037] A second mold base 4 is fixedly mounted on one side of the fixed plate 5 away from the auxiliary plate 503. The second mold base 4 can cooperate with the first mold base 3 to form an injection molding cavity, so that the raw material is condensed and formed in the cavity between the first mold base 3 and the second mold base 4, and then the injection molding process is completed to produce products of corresponding shapes and sizes;

[0038] A heat-conducting ring 1 is fixedly installed on the outer side of the second mold base 4, and heat-dissipating plates 101 are fixedly installed on both sides of the heat-conducting ring 1. The heat-dissipating plates 101 are rectangular mesh structures, and the heat-dissipating plates 101 are made of thermoelectric materials. The heat-conducting ring 1 can contact the second mold base 4, so as to absorb the heat inside the second mold base 4, so as to promote the rapid cooling of the second mold base 4, shorten the cooling time of the raw materials inside the second mold base 4, and improve the efficiency of injection mold processing. The heat-dissipating plates 101 can absorb the heat inside the heat-conducting ring 1 and expand the heat-dissipating area to improve the heat-dissipating efficiency. By energizing the heat-dissipating plates 101, a temperature difference is generated inside the heat-dissipating plates 101 made of thermoelectric materials, so as to quickly transfer the heat inside the second mold base 4, and improve the heat-dissipating efficiency of the heat-conducting ring 1 for the second mold base 4;

[0039] The mounting plate 2 is fixedly mounted on the outer side of the mounting rod 506, and the hydraulic telescopic rod 202 is fixedly mounted on the inner side of the mounting plate 2. The mounting plate 2 can provide a mounting position for the surrounding components, and the hydraulic telescopic rod 202 can be extended and retracted, thereby pushing the first mold base 3 to move, so that the first mold base 3 and the second mold base 4 are fitted together during the injection molding process, and then the product is injection molded. After the processing is completed, the first mold base 3 is pulled apart from the second mold base 4, so as to facilitate demoulding of the product after the injection molding process;

[0040] The first mold base 3 is fixedly installed on one end of the hydraulic telescopic rod 202 close to the second mold base 4, and an air pump 301 is fixedly installed on one side of the first mold base 3 close to the mounting plate 2, and an air suction pipe 302 is fixedly installed on the top of the air suction pump 301. One end of the air suction pipe 302 is fixedly connected to the top of the first mold base 3. The first mold base 3 can be cooperated with the second mold base 4 for injection molding. The air suction pump 301 adopts the KVP-300KD type. After the air suction pump 301 is powered on, it can suck the air inside the first mold base 3 through the air suction pipe 302, so that negative pressure is generated inside the first mold base 3, so as to suck out the product inside the second mold base 4, and then complete the demolding of the product after injection molding.

[0041] Furthermore, the injection assembly 6 includes an injection barrel 603, a discharge hole 610 is provided at the top of the injection barrel 603, a piston plate 608 is movably installed inside the injection barrel 603, the piston plate 608 is a disc-shaped structure, and a sealing ring is fixedly installed on the side of the piston plate 608, a through hole is provided inside the piston plate 608, and a one-way tube 609 is fixedly installed at the top of the piston plate 608 at the position of the through hole, and a plurality of support columns 607 are fixedly installed at the bottom of the injection barrel 603. The injection barrel 603 can provide an installation position for the surrounding components, and can cooperate with the surrounding components to quantitatively inject raw materials, and can inject air into the second mold base 4 to stabilize the air pressure value inside the second mold base 4 to ensure the processing quality and efficiency of the product. The discharge hole 610 can allow the raw material inside the injection barrel 603 to enter the injection tube 602, and then the raw material can enter the second mold base 4 from the injection barrel 603. The piston plate 608 can move inside the injection barrel 603, so as to facilitate quantitative extraction of the raw material in cooperation with the injection barrel 603, and can inject raw material or a proper amount of air into the second mold base 4 to ensure the processing quality of the device for the product. The one-way tube 609 can make the raw material and air on both sides of the piston plate 608 in a one-way flow, so as to prevent the raw material from flowing from the top of the piston plate 608 to the inside of the connecting air pipe 605. The support column 607 can limit the piston plate 608, so that the lowest position of the piston plate 608 is always located above the installation position of the connecting air pipe 605.

[0042] A connecting air pipe 605 is fixedly installed on one side of the injection barrel 603 near the bottom position, and a control air pump 604 is fixedly installed on one end of the connecting air pipe 605, and the control air pump 604 is fixedly connected to the sub-plate 503. A solenoid valve 606 is fixedly installed on one side of the injection barrel 603 near the top position, and a connecting pipe 601 is fixedly installed on one side of the solenoid valve 606. The connecting pipe 601 is externally connected to a plastic raw material injection device. An injection pipe 602 is fixedly installed on the top of the injection barrel 603, and a one-way valve is fixedly installed at the connection position between the injection pipe 602 and the injection barrel 603. The connecting air pipe 605 can be connected to the control air pump 604, so that the control air pump 604 injects air into or draws air from the inside of the injection barrel 603, thereby controlling the movement of the piston plate 608 inside the injection barrel 603 to control The air pump 604 is of ZK-290 type. After the air pump 604 is powered on, it can inject air into or suck air from the inside of the injection barrel 603, thereby adjusting the air pressure value of the cavity between the piston plate 608 and the injection barrel 603 to achieve the purpose of moving the piston plate 608. The solenoid valve 606 can control the switch of the connecting pipe 601, thereby preventing the raw material inside the injection barrel 603 from flowing to the connecting pipe 601 during the injection process. The connecting pipe 601 can be connected to the injection equipment of the plastic raw material or the container for storing the plastic raw material, thereby allowing the plastic raw material to enter the inside of the injection barrel 603. The injection pipe 602 can guide the raw material from the injection barrel 603 to flow into the second mold base 4, so as to fill the injection groove and the injection groove with raw materials, and then use the first mold base 3 and the second mold base 4 for injection molding.

[0043] Furthermore, a limit rod 203 is movably installed on one side of the interior of the mounting plate 2, and the limit rod 203 is fixedly connected to the first mold base 3. A hydraulic controller 201 is fixedly installed on one side of the mounting plate 2, and the hydraulic controller 201 is connected to the hydraulic telescopic rod 202. The limit rod 203 can move synchronously with the first mold base 3, so that the first mold base 3 remains stable during the movement, avoiding deviation when the hydraulic telescopic rod 202 pushes the first mold base 3. The hydraulic controller 201 can control the hydraulic telescopic rod 202, thereby adjusting the telescopic direction and telescopic length of the hydraulic telescopic rod 202.

[0044] Furthermore, two ventilation slots are provided inside the fixed plate 5, and a ventilation net 502 is fixedly installed on one side of the ventilation slots, and a heat dissipation fan 501 is fixedly installed on one side of the ventilation net 502. The ventilation slots and the ventilation net 502 can allow air to circulate inside the fixed plate 5, thereby allowing the heat dissipation fan 501 to cool the heat dissipation plate 101, thereby further improving the heat dissipation efficiency of the heat dissipation plate 101. The heat dissipation fan 501 adopts the FDL-4C type. After the heat dissipation fan 501 is powered on, it can drive the air flow, thereby cooling the heat dissipation plate 101, thereby improving the efficiency of product molding in the injection molding process.

[0045] Furthermore, a threaded hole is formed on one side of the mounting rod 506 , and the mounting rod 506 is fixedly connected to the mounting plate 2 by a bolt, and one end of the bolt extends into the inside of the threaded hole.

[0046] Furthermore, a limit cover is installed at one end of the mounting rod 506 away from the fixed plate 5 through a threaded structure, and the diameter of the limit cover is larger than the mounting rod 506. The limit cover can limit the mounting plate 2, thereby ensuring the installation stability of the mounting plate 2 on the mounting rod 506 and preventing the mounting plate 2 from falling off the mounting rod 506.

[0047] Furthermore, an air flow channel is opened inside the first mold base 3, and the air flow channel is connected to the exhaust pipe 302. A plurality of injection molding grooves are opened on the side of the first mold base 3 close to the second mold base 4. The air flow channel can connect the exhaust pipe 302 with the plurality of injection molding grooves, so that the exhaust pump 301 can evacuate the inside of the injection molding groove to generate negative pressure, and then use the negative pressure to apply suction to the product, so as to facilitate demolding of the product.

[0048] Furthermore, a flow guide is provided inside the second mold base 4, and the flow guide is connected to the connecting pipe 601. A plurality of injection grooves are provided inside the second mold base 4, and the injection grooves are connected to the flow guide. The flow guide can make the raw material flow evenly to the plurality of injection grooves, thereby allowing the raw material to be cooled and formed between the injection grooves and the injection molding groove.

[0049] Working principle: After the device is assembled and checked and confirmed to be correct, the air pump 604 is controlled to evacuate the injection barrel 603, so that the piston plate 608 moves downward, expanding the space above the piston plate 608, allowing the raw material to enter the interior of the injection barrel 603 through the connecting pipe 601, and the solenoid valve 606 is closed. The hydraulic controller 201 controls the hydraulic telescopic rod 202 to extend and retract, so that the first mold base 3 and the second mold base 4 are plugged and connected, and the air pump 604 is controlled to fill the interior of the injection barrel 603 with air through the connecting air pipe 605, so that the piston plate 608 moves upward and pushes the raw material from the injection pipe 602 into the cavity between the second mold base 4 and the first mold base 3. After the raw material enters several injection grooves and injection grooves through the injection pipe 602 and the injection groove, the several injection grooves and injection grooves are filled. After the raw material completely fills the injection grooves and injection grooves, the top of the piston plate 608 contacts the top of the inner wall of the injection barrel 603, and the air passes through The one-way tube 609 enters the injection tube 602 to allow air to fill the guide channel. When the air pressure values ​​on the upper and lower sides of the piston plate 608 are equal, the one-way tube 609 is closed, and the raw material is cooled and formed inside the injection groove and the injection groove. The heat inside the second mold base 4 is absorbed by the heat conductive ring 1 and transferred to the heat sink 101. After the heat sink 101 is energized, its local temperature drops to form a temperature difference, which accelerates the heat to enter the heat sink 101. After the heat dissipation fan 501 is energized, it blows air to the heat sink 101, so that the heat sink 101 is air-cooled and dissipated, thereby rapidly reducing the temperature of the second mold base 4, promoting the cooling and forming of the products inside the first mold base 3 and the second mold base 4. When the raw material is completely cooled to form a product, the hydraulic telescopic rod 202 retracts to pull the first mold base 3 and the second mold base 4 apart. At the same time, the vacuum pump 301 evacuates the interior of the first mold base 3 to generate negative pressure in the first mold base 3 and the injection groove, and the product is sucked out of the injection groove to complete demolding.
