Description

Technical Field

[0001] This invention relates to, but is not limited to, the technical field of split molds, and particularly to a split LED lamp mold opening device. Background Technology

[0002] LED lighting fixtures are lighting devices that use LEDs as the light source. Due to their energy-saving and long-life performance, they have been widely used. Most LED lighting fixtures are composed of components such as LED light sources, control circuit boards, and housings. The various components of LED lighting fixtures are processed through different manufacturing processes and then assembled through automated production lines.

[0003] The housing of the LED lamp is processed by injection molding equipment. The specific process is to inject flowing resin raw material into the mold. After cooling, once it is basically formed, the mold opening device is activated, the mold opens, and the pusher component pushes the housing off the mold to prevent the housing from sticking or getting stuck on the mold.

[0004] Patent publication number CN111318643B discloses a mold opening device for a split mold. The device is mounted on a split mold containing a sand core. It includes a base, a drive assembly, a transmission assembly, a top core plate, and several top core rods. The top core plate is positioned on one side of the mold in the opening / closing direction. Each top core rod is fixed perpendicularly to the top core plate at intervals and faces the mold. A through hole matching the top core rod is provided on the opening / closing side of the mold. The drive assembly is mounted on the opening / closing side of the mold. The transmission assembly is mounted on the top core plate. The drive assembly drives the transmission assembly to move, and the transmission assembly's movement causes the top core rods to pass through the mold through holes and move towards the sand core. The top core rods press against the sand core inside the mold, and the reaction force of the sand core acts on the first split mold, forcing it to move in the opposite direction and thus detach from the sand core. This design ensures smooth mold opening without damaging the sand core, improving efficiency and reducing costs.

[0005] The aforementioned patent has the following defects:

[0006] When the manufactured product has a certain degree of flexibility and a large diameter span, there may be large areas of sticking or jamming. Demolding is performed by pushing the pusher component, which forms one or more force points on the product. All the force exerted by the pusher component on the product diffuses outward through these force points until it reaches all sticking or jamming areas, thus completing the demolding. During this process, the force on the force points is relatively concentrated, and before the force at the force points diffuses outward, the product needs to undergo a large elastic deformation to release all of its own elastic buffer. At this time, the product has not been completely cooled, and the large elastic deformation may form a certain degree of permanent deformation, resulting in a decrease in product quality and affecting product function.

[0007] The ejector component pushes the product away after the mold opens. The specific process is as follows: the mold opens, the punch and die separate, and the product first separates from the mold with weaker binding force (i.e., the side where the product is more loosely attached to the mold). It then continues to attach to the mold with stronger binding force (i.e., the side where the product is more firmly attached to the mold). During this process, both the inner and outer sides of the product are subjected to tensile forces, and the force state is relatively balanced. Then, the ejector component pushes the product away from the mold (i.e., the side where the product is more firmly attached to the mold). At this time, the product is only subjected to force on one side, and the side where the attachment is stronger is subjected to greater force. These forces may also cause the product to deform. Summary of the Invention

[0008] In view of the fact that the existing technology has problems such as unbalanced force applied by the pushing component when the product is demolded, and unbalanced multiple external forces on the product, which leads to product deformation, reduced product quality and affected product function, a split-type LED lamp mold opening device is proposed.

[0009] One aspect of this application provides a mold opening device for split LED lamp molds, the purpose of which is to balance the force on the product and prevent product deformation.

[0010] The technical solution of the present invention is as follows: a mold opening device for split LED lamp mold, comprising two base plates, templates respectively disposed on the surfaces of the two base plates, a punch and a die disposed on opposite sides of the two templates, a guide groove and a guide rod disposed on opposite sides of the templates, and a fixed back plate and a track rod disposed on the side of the templates, and further comprising a demolding unit;

[0011] The track rod passes through the fixed back plate, and the punch and die form an injection space, in which the lamp housing is installed.

[0012] The demolding unit is disposed on the template and is used for demolding the lamp housing;

[0013] The demolding unit includes an installation groove on one side of the two templates facing away from each other, a sliding insertion hole on the surface of the punch and die, a rotating disk inside the installation groove, a boss on the side of the rotating disk near the inside of the installation groove, a sliding hole on the surface of the boss, a sliding groove on the inner wall of the sliding hole, a push rod inside the rotating disk, and a slider on the outside of the push rod.

[0014] The mounting groove corresponds to the distribution positions of the punch and die, and the punch and die are concentrically set with the mounting groove at the corresponding positions. The sliding insertion hole extends into the mounting groove. The sliding insertion hole is distributed in a ring array with the center of the mounting groove as the axis. The sliding hole passes through the rotating disk and the boss. One end of the push rod is flush with the opening of the sliding insertion hole, and the other end passes through the sliding hole. Both the boss and the sliding hole are arc-shaped, and the arc length is greater than the diameter of the push rod. The slider is slidably installed in the sliding groove.

[0015] The demolding unit also includes a drive assembly and a power assembly, which are interconnected.

[0016] The drive assembly is used to drive the rotating disk, and the power assembly is used to provide power for the operation of the drive assembly.

[0017] By employing the above scheme, ejector pins are installed on the surfaces of both the punch and the die. During mold opening, the power component is compressed, transmitting power to the rotating disk via the drive component. The rotating disk rotates and pushes the ejector pins out of the sliding insertion hole through the sliding groove. The ejector pins inside the punch and the die are pushed out simultaneously. In this way, the punch and the die retract to both sides, and the two sets of ejector pins retract to the middle. The arrayed ejector pins evenly apply the thrust to the lamp housing, preventing deformation. At the same time, the lamp housing separates from the punch and the die simultaneously. The inner and outer surfaces of the lamp housing are subjected to the tensile force of separation from the punch or the die, and the forces on both sides partially cancel each other out, making the force on the lamp housing more even. When the ejector pin pushes the lamp housing, both sides of the contact point between the ejector pin and the lamp housing are subjected to thrust, which can maintain a balanced state and further prevent the lamp housing from deforming due to external force during demolding.

[0018] Furthermore, the sliding groove is divided into two sections, one of which slopes downward and the other slopes upward.

[0019] By employing the above scheme, after the push rod pushes the lamp housing to separate from the punch and die using a sliding groove, the sliding groove controls the push rod to retract briefly. The push rods on both sides retract synchronously to separate from the lamp housing. The protrusion allows the lamp housing to separate from the mold in two stages (first from the punch and die, then from the push rod), dispersing the force that the lamp housing will bear during the demolding process, reducing the impact of this force on the shape of the lamp housing, and helping to ensure the integrity of the lamp housing. At the same time, during the separation process between the push rod and the lamp housing, the two sides of the lamp housing also generate tensile forces synchronously. The forces on both sides cancel each other out, making the lamp housing more evenly stressed.

[0020] Furthermore, the power assembly includes an air collection groove disposed on the side of the template near the base plate, a connecting slot disposed between the air collection groove and the connecting slot, a pressurized air hole disposed on the side of the base plate away from the template, an inner air cylinder disposed inside the pressurized air hole, a pressurized air hole extending from the end of the inner air cylinder away from the template, an outer sleeve disposed on the outside of the inner air cylinder, and an inner piston rod disposed on the inside of the outer sleeve.

[0021] The pressurized air hole penetrates the base plate and is connected to the air collection groove. The end of the outer sleeve away from the inner air cylinder touches the surface of the fixed back plate. The outer sleeve is slidably sleeved on the outside of the inner air cylinder, and the inner piston rod is slidably inserted into the inside of the inner air cylinder.

[0022] The drive assembly includes a fixing member disposed inside the mounting groove, an arc-shaped sleeve disposed inside the fixing member, an arc-shaped piston rod disposed inside the arc-shaped sleeve, a pusher disposed outside the rotating disk, the pusher being fixedly installed with the arc-shaped piston rod, and a connecting hose disposed between the arc-shaped sleeve and the connecting slot.

[0023] Both the arc-shaped sleeve and the arc-shaped piston rod are arc-shaped, and the arc is concentric with the rotating disk. The arc-shaped sleeve and the arc-shaped piston rod surround the outside of the rotating disk.

[0024] Using the above scheme, the power unit provides power to the rotating disk. When the base plate moves to open the mold, the outer sleeve squeezes and fixes the back plate. The inner piston rod slides in the inner air cylinder to convert air pressure into power. The ejector rod and the two base plates work together to make the process more stable. At the same time, the outer sleeve wraps around the inner piston rod to prevent the inner piston rod from being disturbed by external factors (dust, production waste, etc.).

[0025] Furthermore, the demolding unit also includes a connecting component, which is used to control the synchronous movement of the driving components on the two templates;

[0026] The connecting component includes an inner hole disposed inside the guide rod, a connecting channel disposed inside the template, and an outer hole disposed outside the guide rod.

[0027] The outer hole is connected to the inner hole, the left connecting channel connects the gas collecting groove and the inner hole, and the right connecting channel connects the gas collecting groove and the guide groove.

[0028] By adopting the above scheme, when the power component injects air into the air collection groove inside the punch, some air enters through the connecting slot and acts on the drive component, while some air enters the inner hole through the connecting channel and then enters the connecting channel inside the right template through the outer hole. The air flows into the air collection groove, which makes the ejector rod inside the template and the drive component inside the punch start synchronously, so that the ejector rods on both sides always move synchronously, ensuring the stability of the demolding process.

[0029] Furthermore, the inner diameter of the inner air cylinder is the same as the sum of the inner diameters of the arc-shaped sleeves in the two templates, and the inclination angle of the sliding groove is forty-five degrees.

[0030] Using the above scheme, the air discharged from the inner air cylinder is evenly distributed into the arc-shaped sleeves of the two templates. When the inner air cylinder moves two units, the push rods on both sides move one unit. During the demolding process, when one template moves, the push rods on both sides push out half the distance (the sum of the displacement distances of the push rods on both sides equals the movement distance of the template), so that the lamp housing is set in the middle position of the two templates, making the demolding process smoother.

[0031] Furthermore, an auxiliary peeling unit is provided inside the base plate to assist the top rod in removing the film from the lamp housing;

[0032] The auxiliary stripping unit includes a ventilation component for venting air into the injection space;

[0033] The ventilation assembly includes an air supply chamber disposed inside the base plate, a through hole disposed on the side of the base plate near the template, and an air supply hole disposed inside the top rod.

[0034] The through hole is connected to the air supply chamber, and the push rod extends through the through hole into the air supply chamber. The push rod extends from both ends of the air supply hole, and the air supply chamber is connected to an air blowing device.

[0035] By adopting the above scheme and setting up a ventilation component, when the mold is opened, the air blowing device fills the air supply cavity with air, and the ejector rod pushes forward, applying a thrust to the lamp housing. Since the lamp housing has a certain degree of flexibility, it will be pushed by the ejector rod to produce a slight deformation before the lamp housing is demolded. The movement of the ejector rod also exposes the air supply hole on its side, and the air in the air supply cavity flows out and diffuses from the ejector rod to the surroundings, assisting the demolding of the lamp housing and reducing the external force interference it receives during demolding.

[0036] Furthermore, the auxiliary stripping unit also includes a control component for controlling the air supply status of the ventilation component;

[0037] The control assembly includes a sealing groove disposed on the inner wall of the air supply chamber, a slot disposed on the inner wall of the sealing groove, a side plate disposed on the inner wall of the air supply chamber, a push spring and a connecting air pipe disposed inside the sealing groove, a side air hole and a control hole disposed on the surface of the connecting air pipe, a main rod disposed inside the control hole, a rotating rod disposed on one end of the main rod near the inner side of the connecting air pipe, a secondary spring disposed on the other end of the air supply chamber, a compression plate disposed on the outer side of the main rod, a main spring disposed between the compression plate and the inner wall of the control hole, and a locking rod disposed on the end of the secondary spring away from the main rod.

[0038] The side plate surrounds the opening of the closed groove, and the push rod is slidably inserted into the connecting air pipe. The bottom wall of the push rod is set as a conical surface, and the side air holes and control holes are distributed in a cross shape.

[0039] By adopting the above solution and setting up control components, when the top rod moves slightly, the locking rod, main rod, and rotating rod lose their restraints. The connecting air pipe is quickly reset under the push of the top spring, the side air hole exposes the closed groove, and the air supply hole is connected to the air supply chamber. The air in the air supply chamber can be discharged in large quantities and quickly, so that the air can quickly play an auxiliary role in peeling and reduce the impact of the top rod on the lamp housing.

[0040] Furthermore, the opening of the sliding insertion hole at one end of the injection space is set in the shape of a flared mouth, the end of the push rod near the injection space has the same shape as the opening of the sliding insertion hole, and the opening of the air supply hole is located on the mating surface of the push rod and the sliding insertion hole.

[0041] Using the above solution, a slight displacement of the top rod allows the air supply hole to be fully opened, enabling air to quickly play an auxiliary role in the stripping process and reducing the impact of the top rod on the lamp housing.

[0042] Furthermore, the present invention also provides a method for using the mold-opening device for split LED lamp molds, including the following steps:

[0043] Step 1: Start the equipment. The displacement device moves the base plates and templates on the left and right sides to close. The two templates fit together, and the punch and die cooperate to form an injection space. The injection equipment injects flowing resin raw material into the injection space through the injection channel and waits for it to cool and solidify.

[0044] Step 2: After the raw material is formed, the displacement device drives the left and right base plates and templates to separate. During the movement of the base plates, the extrusion power component is squeezed. The power component injects air into the drive component. The drive component pushes the rotating disk to rotate. During the rotation of the rotating disk, the ejector rod is driven to move into the injection space through the cooperation of the sliding groove and the slider. The ejector rods on the surfaces of the punch and the die extend synchronously.

[0045] Step 3: When the ejector rod initially enters the injection space, due to the flexibility of the lamp housing, the ejector rod will first undergo slight deformation due to the force during the process of pushing the lamp housing to move and separate. A gap will appear between the lamp housing around the ejector rod and the punch or die. The air in the side plate is injected into this gap through the air supply hole. The air diffuses from the gap to the surrounding area, gradually peeling the lamp housing from the punch and die.

[0046] Step 4: As the distance of the ejector pins increases, the ejector pins on both sides clamp the lamp housing and separate it from the punch and die. Then, guided by the sliding groove, the ejector pins retract a certain distance into the sliding insertion hole. At the same time, the ejector pins on both sides pull the lamp housing, causing the lamp housing to separate from the ejector pins, thus completing the demolding.

[0047] Furthermore, before starting the equipment in step one, the surfaces of the punch and die are cleaned.

[0048] The beneficial effects of this invention are:

[0049] 1. By setting ejector pins on the surfaces of both the punch and the die, during mold opening, the power component is compressed, transmitting power to the rotating disk through the drive component. The rotating disk rotates and pushes the ejector pins out of the sliding hole through the sliding groove. The ejector pins in the punch and the die are pushed out simultaneously. In this way, the punch and the die retract to both sides, and the two sets of ejector pins retract to the middle. The array of ejector pins evenly applies the thrust to the lamp housing, avoiding deformation. At the same time, the lamp housing separates from the punch and the die simultaneously. The inner and outer surfaces of the lamp housing are subjected to the pulling force of separating from the punch or the die, and the forces on both sides cancel each other out, making the force on the lamp housing more even. When the ejector pin pushes the lamp housing, both sides of the contact point between the ejector pin and the lamp housing are subjected to the thrust, which can maintain a balanced state and further prevent the lamp housing from deforming due to external force during demolding.

[0050] 2. By setting ejector pins on the surfaces of both the punch and the die, during mold opening, the power component is compressed, transmitting power to the rotating disk through the drive component. The rotating disk rotates and pushes the ejector pins out of the sliding insertion hole through the sliding groove. The ejector pins in the punch and the die are pushed out simultaneously. In this way, the punch and the die retract to both sides, and the two sets of ejector pins retract to the middle. The array of ejector pins evenly applies the thrust to the lamp housing, avoiding deformation. At the same time, the lamp housing separates from the punch and the die simultaneously. The inner and outer surfaces of the lamp housing are subjected to the pulling force of separating from the punch or the die, and the forces on both sides cancel each other out, making the force on the lamp housing more even. When the ejector pin pushes the lamp housing, both sides of the contact point between the ejector pin and the lamp housing are subjected to the thrust, which can maintain a balanced state and further prevent the lamp housing from deforming due to external force during demolding.

[0051] 3. By setting up a connecting component, when the power component injects air into the air collection groove inside the punch, some air enters through the connecting slot and acts on the drive component, while some air enters the inner hole through the connecting channel and then enters the connecting channel inside the right template through the outer hole. The air flows into the air collection groove, causing the ejector rod inside the template and the drive component inside the punch to start synchronously, ensuring that the ejector rods on both sides always move synchronously and guaranteeing the stability of the demolding process.

[0052] 4. By setting up a ventilation component, when the mold is opened, the air blowing device fills the air supply cavity with air, and the ejector rod pushes forward, applying a thrust to the lamp housing. Since the lamp housing has a certain degree of flexibility, it will be pushed by the ejector rod to produce a slight deformation before the lamp housing is demolded. The movement of the ejector rod also exposes the air supply holes on its side, and the air in the air supply cavity flows out and diffuses from the ejector rod to the surroundings, assisting the demolding of the lamp housing and reducing the external force interference it receives during demolding.

[0053] 5. By setting up control components, when the top rod moves slightly, the locking rod, main rod, and rotating rod lose their restraints. The connecting air pipe is quickly reset under the push of the top spring, the side air hole exposes the closed groove, and the air supply hole is connected to the air supply chamber. The air in the air supply chamber can be discharged in large quantities and quickly, so that the air can quickly play an auxiliary role in peeling and reduce the impact of the top rod on the lamp housing.

[0074] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0075] Example 1, referring to Figure 1-14 The first embodiment of the present invention provides a mold opening device for split LED lamp molds, including two base plates 1 on the left and right, templates 2 respectively disposed on the surfaces of the two base plates 1, a punch 3 and a die 4 disposed on opposite sides of the two templates 2, a guide groove 5 and a guide rod 6 disposed on opposite sides of the templates 2, and a fixed back plate 8 and a track rod 9 disposed on the side of the templates 2.

[0076] Specifically, the track rod 9 passes through the fixed back plate 8, the punch 3 and the die 4 form an injection space, the lamp housing is set in the injection space, and a demolding unit is also included. The base plate 1 and the template 2 are symmetrically arranged and fixed to each other by bolts. The guide rod 6 is correspondingly arranged with the guide groove 5, and the guide rod 6 can be slidably inserted into the guide groove 5.

[0077] The demolding unit is set on template 2 and is used for demolding the lamp housing;

[0078] The demolding unit includes a mounting groove 10 on one side of the two templates 2 facing away from each other, a sliding insertion hole 11 on the surface of the punch 3 and the die 4, a rotating disk 12 inside the mounting groove 10, a boss 13 on the side of the rotating disk 12 near the inside of the mounting groove 10, a sliding hole 14 on the surface of the boss 13, a sliding groove 15 on the inner wall of the sliding hole 14, a push rod 16 inside the rotating disk 12, and a slider 17 on the outside of the push rod 16.

[0079] Specifically, the mounting groove 10 corresponds to the distribution positions of the punch 3 and the die 4, and the punch 3 and the die 4 are concentrically set with the mounting groove 10 at the corresponding positions. The sliding insertion hole 11 extends into the mounting groove 10. The sliding insertion hole 11 is distributed in a ring array with the center of the mounting groove 10 as the axis. The sliding hole 14 passes through the rotating disk 12 and the boss 13. One end of the ejector rod 16 is flush with the opening of the sliding insertion hole 11, and the other end passes through the sliding hole 14. The boss 13 and the sliding hole 14 are both arc-shaped, and the arc length is greater than the diameter of the ejector rod 16. The slider 17 is slidably installed in the sliding groove 15, and the rotating disk 12 is rotatably connected to the mounting groove 10.

[0080] Referring to Figure 512, the demolding unit also includes a drive assembly 18 and a power assembly 19, which are interconnected.

[0081] The power unit 19 is used to drive the rotating disk 12 and to provide power for the operation of the drive unit 18.

[0082] By adopting the above scheme, ejector pins 16 are provided on the surfaces of both the punch 3 and the die 4. When the mold is opened, the power component 19 is squeezed and transmits power to the rotating disk 12 through the drive component 18. The rotating disk 12 rotates and pushes the ejector pins 16 outward through the sliding groove 15. The ejector pins 16 in the punch 3 and the die 4 are pushed out simultaneously. In this way, the punch 3 and the die 4 retract to both sides, and the two sets of ejector pins 16 retract to the middle. The array of ejector pins 16 evenly applies the pushing force to the lamp housing, avoiding deformation. At the same time, the lamp housing separates synchronously with the punch 3 and the die 4. The inner and outer surfaces of the lamp housing are subjected to the pulling force of separating from the punch 3 or the die 4. The forces on both sides cancel each other out, making the force on the lamp housing more even. When the ejector pins 16 push the lamp housing, both sides of the contact point between the ejector pins 16 and the lamp housing are subjected to the pushing force, which can maintain a balanced state and further prevent the lamp housing from deforming due to external force during demolding.

[0083] Specifically, the sliding groove 15 is divided into two sections, one of which is inclined downwards and the other is inclined upwards.

[0084] Using the above scheme, by utilizing the sliding groove 15, the ejector rod 16 pushes the lamp housing to separate from the punch 3 and the die 4. The sliding groove 15 controls the ejector rod 16 to retract briefly, and the ejector rods 16 on both sides retract synchronously to separate from the lamp housing. The protrusion allows the lamp housing to separate from the mold in two stages (first from the punch 3 and the die 4, and then from the ejector rod 16). This disperses the force that the lamp housing will bear during the demolding process, reduces the impact of this force on the shape of the lamp housing, and helps to ensure the integrity of the lamp housing. At the same time, during the separation process between the ejector rod 16 and the lamp housing, the two sides of the lamp housing also generate a pulling force synchronously. The forces on both sides cancel each other out, making the lamp housing more evenly stressed.

[0085] The power assembly 19 includes an air collection groove 21 disposed on the side of the template 2 near the base plate 1, a connecting slot 22 disposed between the air collection groove 21 and the connecting slot 22, a pressurized air hole 23 disposed on the side of the base plate 1 away from the template 2, an inner air cylinder 24 disposed inside the pressurized air hole 23, the end of the inner air cylinder 24 away from the template 2 extending out of the pressurized air hole 23, an outer sleeve 25 disposed on the outer side of the inner air cylinder 24, and an inner piston rod 26 disposed on the inner side of the outer sleeve 25.

[0086] Specifically, the air supply port 23 penetrates the base plate 1 and is connected to the air collection groove 21. The end of the outer sleeve 25 away from the inner air cylinder 24 touches the surface of the fixed back plate 8. The outer sleeve 25 is slidably sleeved on the outside of the inner air cylinder 24. The inner piston rod 26 is slidably inserted into the inside of the inner air cylinder 24. A return spring is provided between the outer sleeve 25 and the inner air cylinder 24.

[0087] The drive assembly 18 includes a fixing member 27 disposed inside the mounting groove 10, an arc-shaped sleeve 28 disposed inside the fixing member 27, an arc-shaped piston rod 29 disposed inside the arc-shaped sleeve 28, a pusher 30 disposed outside the rotating disk 12, the pusher 30 being fixedly installed with the arc-shaped piston rod 29, and a connecting hose 31 disposed between the arc-shaped sleeve 28 and the connecting slot 22;

[0088] Specifically, both the arc-shaped sleeve 28 and the arc-shaped piston rod 29 are arc-shaped, and the arc is concentric with the rotating disk 12. The arc-shaped sleeve 28 and the arc-shaped piston rod 29 surround the outside of the rotating disk 12.

[0089] Using the above scheme, the power component 19 provides power to the rotating disk 12. When the base plate 1 moves to open the mold, the outer sleeve 25 presses against the fixed back plate 8. The inner piston rod 26 slides in the inner air cylinder 24 to convert air pressure into power. The push rod 16 and the two base plates 1 work together to make the process more stable. At the same time, the outer sleeve 25 wraps the inner piston rod 26 to prevent the inner piston rod 26 from being disturbed by external factors (dust, production waste, etc.).

[0090] Reference Figure 13-14The demolding unit also includes a connecting component 20, which is used to control the synchronous movement of the driving components 18 on the two templates 2;

[0091] The connecting component 20 includes an inner hole 32 disposed inside the guide rod 6, a connecting channel 33 disposed inside the template 2, and an outer hole 34 disposed outside the guide rod 6.

[0092] Specifically, the outer hole 34 is connected to the inner hole 32, the left connecting channel 33 connects the gas collecting groove 21 and the inner hole 32, and the right connecting channel 33 connects the gas collecting groove 21 and the guide groove 5.

[0093] By adopting the above scheme, when the power component 19 injects air into the air collection groove 21 inside the punch 3 through the connecting slot 22, some air enters through the connecting slot 22 and acts on the drive component 18, and some air enters the inner hole 32 through the connecting channel 33, and then enters the connecting channel 33 inside the right template 2 through the outer hole 34. The air flows into the air collection groove 21, so that the ejector rod 16 inside the template 2 and the drive component 18 inside the punch 3 start synchronously, so that the ejector rods 16 on both sides always move synchronously, ensuring the stability of the demolding process.

[0094] The inner diameter of the inner air cylinder 24 is the same as the sum of the inner diameters of the arc-shaped sleeves 28 in the two templates 2, and the inclination angle of the sliding groove 15 is forty-five degrees.

[0095] Using the above scheme, the air discharged from the inner air cylinder 24 is evenly distributed into the arc-shaped sleeves 28 of the two templates 2. The inner air cylinder 24 moves a distance of two units, while the top rods 16 on both sides move a distance of one unit. During the demolding process, one template 2 moves, and the top rods 16 on both sides push out half the distance (the sum of the displacement distances of the top rods 16 on both sides equals the movement distance of the template 2), so that the lamp housing is set in the middle position of the two templates 2, making the demolding process smoother.

[0096] During use, the displacement device causes the left base plate 1 and template 2 to separate from the right base plate 1 and template 2. The left base plate 1 and template 2 move to reduce the distance between them and the fixed back plate 8. The outer sleeve 25 is squeezed and pushes the inner piston rod 26 deeper into the inner air cylinder 24. The air in the inner air cylinder 24 is pushed into the pressure supply hole 23 and then flows into the air collection groove 21. The air in the air collection groove 21 also enters the arc sleeve 28 directly through the connecting slot 22. The arc sleeve 28 is filled with air and pushes the arc piston rod 29 outward. The arc piston rod 29 rotates around the axis of the rotating disk 12. The rotation of the arc piston rod 29 pushes the rotating disk 12 to deflect through the pusher 30. The rotating disk 12 causes the position of the sliding hole 14 to change. The slider 17 slides in the upward inclined section of the sliding groove 15. During the sliding process, the slider 17 is pushed by the inclined surface and drives the push rod 16 to move outward of the sliding insertion hole 11. The push rod 16 on the surface of the punch 3 and the die 4 extends synchronously.

[0097] Guided by the sliding groove 15, the push rod 16 continues to push forward, pushing the lamp housing. The movement distance of the push rod 16 increases continuously. The push rods 16 on both sides clamp the lamp housing and separate it from the punch 3 and the die 4 (at this time, the push rod 16 reaches the maximum displacement distance). Then, guided by the downward inclined section of the sliding groove 15, the push rod 16 retracts a distance into the sliding insertion hole 11. The push rods 16 on both sides pull the lamp housing at the same time, so that the lamp housing separates from the push rod 16, and the demolding is completed.

[0098] Example 2, refer to Figure 15-16 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that an auxiliary peeling unit is provided in the base plate 1 to assist the top rod 16 in peeling the lamp housing.

[0099] The auxiliary stripping unit includes a ventilation assembly 35 for venting air into the injection space;

[0100] The ventilation assembly 35 includes an air supply chamber 37 disposed inside the base plate 1, a through hole 38 disposed on the side of the base plate 1 near the template 2, and an air supply hole 39 disposed inside the top rod 16.

[0101] Specifically, the through hole 38 is connected to the air supply chamber 37, the push rod 16 extends through the through hole 38 into the air supply chamber 37, the push rod 16 extends from both ends of the air supply hole 39, and the air supply chamber 37 is connected to an external air blowing device.

[0102] Using the above scheme, by setting the ventilation component 35, when the mold is opened, the air blowing device fills the air supply chamber 37 with air, and the ejector rod 16 pushes forward, applying a thrust to the lamp housing. Since the lamp housing has a certain degree of flexibility, it will be pushed by the ejector rod 16 to produce a slight deformation before the lamp housing is demolded. The movement of the ejector rod 16 also exposes the air supply hole 39 on its side, and the air in the air supply chamber 37 flows out and diffuses from the ejector rod 16 to the surrounding area, assisting the demolding of the lamp housing and reducing the external force interference it receives during demolding.

[0103] During use, air from the inner air cylinder 24 enters the air collection groove 21. Half of the air in the air collection groove 21 enters the arc-shaped sleeve 28 directly through the connecting slot 22, and the other half of the air enters the inner hole 32 through the connecting channel 33, and then enters the connecting channel 33 in the right template 2 through the outer hole 34. The air in the connecting channel 33 flows into the air collection groove 21, so that the drive components 18 in both templates 2 are powered synchronously, and the push rods 16 on both sides are pushed out synchronously.

[0104] The remaining structure is the same as that in Example 1.

[0105] Example 3, referring to Figure 14-18This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the auxiliary stripping unit further includes a control component 36 for controlling the air supply status of the ventilation component 35.

[0106] The control assembly 36 includes a closed groove 40 disposed on the inner wall of the air supply chamber 37, a slot 42 disposed on the inner wall of the closed groove 40, a side plate 41 disposed on the inner wall of the air supply chamber 37, a push spring 43 and a connecting air pipe 44 disposed inside the closed groove 40, a side air hole 45 and a control hole 46 disposed on the surface of the connecting air pipe 44, a main rod 47 disposed inside the control hole 46, a rotating rod 48 disposed on one end of the main rod 47 near the inner side of the connecting air pipe 44, a secondary spring 51 disposed on the other end of the air supply chamber 37, a compression plate 49 disposed on the outer side of the main rod 47, a main spring 50 disposed between the compression plate 49 and the inner wall of the control hole 46, and a locking rod 52 disposed on the end of the secondary spring 51 away from the main rod 47.

[0107] Specifically, the side plate 41 surrounds the opening of the closed groove 40. The distance between the inner wall of the side plate 41 and the connecting air pipe 44 is greater than the distance between the inside of the closed groove 40 and the connecting air pipe 44. The top rod 16 is slidably inserted into the inside of the connecting air pipe 44. The bottom wall of the top rod 16 is set as a conical surface. The side air hole 45 and the control hole 46 are arranged in a cross shape. A torsion spring is set between the rotating rod 48 and the compression plate 49. The force required to stretch the torsion spring is greater than the force required to compress the main spring 50, but less than the sum of the forces required to compress the main spring 50 and the auxiliary spring 51.

[0108] Using the above scheme, by setting the control component 36, when the top rod 16 is slightly displaced, the locking rod 52, the main rod 47, and the rotating rod 48 lose their restraints. The connecting air pipe 44 is quickly reset under the push of the push spring 43, the side air hole 45 exposes the closed groove 40, the air supply hole 39 is connected to the air supply chamber 37, and the air in the air supply chamber 37 can be discharged in large quantities and quickly, so that the air can quickly play an auxiliary peeling role and reduce the impact of the top rod 16 on the lamp housing.

[0109] Specifically, the opening of the sliding socket 11 at one end of the injection space is set in the shape of a flared mouth, the end of the ejector rod 16 near the injection space has the same shape as the opening of the sliding socket 11, and the opening of the air supply hole 39 is located on the mating surface of the ejector rod 16 and the sliding socket 11.

[0110] Using the above solution, the top rod 16 will shift slightly, and the air supply hole 39 can be fully opened, allowing air to quickly play an auxiliary role in peeling off and reducing the impact of the top rod 16 on the lamp housing.

[0111] The remaining structure is the same as that in Example 2.

[0112] Example 4, refer to Figure 1-18The fourth embodiment of the present invention provides a method for using a mold-opening device for split-type LED lamp molds, comprising the following steps:

[0113] Step 1: Clean the surfaces of the punch 3 and the die 4, start the equipment, and the displacement device will drive the base plates 1 and templates 2 on the left and right sides to close together. The two templates 2 will fit together, and the punch 3 and the die 4 will cooperate to form an injection space. The injection equipment will inject flowing resin raw material into the injection space through the injection channel 7 and wait for it to cool and solidify.

[0114] Step Two: After the raw material is formed, the displacement device causes the left base plate 1 and template 2 to separate from the right base plate 1 and template 2. The left base plate 1 and template 2 move, reducing the distance between them and the fixed back plate 8. The outer sleeve 25 is compressed, pushing the inner piston rod 26 deeper into the inner air cylinder 24. The air in the inner air cylinder 24 is pushed into the pressure supply hole 23 and then flows into the air collection groove 21. Half of the air in the air collection groove 21 enters the arc-shaped sleeve 28 directly through the connecting slot 22, and the other half enters the inner hole 32 through the connecting channel 33, and then enters the connecting channel 33 in the right template 2 through the outer hole 34. Air flows into the air collection groove 21, and the air in the air collection groove 21 also enters the arc-shaped sleeve 28 directly through the connecting slot 22. The arc-shaped sleeve 28 is filled with air, which pushes the arc-shaped piston rod 29 outward. The arc-shaped piston rod 29 rotates around the axis of the rotating disk 12. The rotation of the arc-shaped piston rod 29 pushes the rotating disk 12 to deflect through the pusher 30. The rotating disk 12 causes the position of the sliding hole 14 to change. The slider 17 slides in the upward inclined section of the sliding groove 15. During the sliding process, the slider 17 is pushed by the inclined surface, which drives the ejector rod 16 to move outward of the sliding insertion hole 11. The ejector rod 16 on the surface of the punch 3 and the die 4 extends synchronously.

[0115] Step 3; When the ejector pin 16 initially enters the injection space, due to the flexibility of the lamp housing, the ejector pin 16 will undergo slight deformation due to the force during the process of pushing the lamp housing to move and separate. A gap will appear between the lamp housing around the ejector pin 16 and the punch 3 or die 4. The movement of the ejector pin 16 will expose the air supply hole 39 on its side. Figure 10As shown, the movement of the push rod 16 simultaneously causes the rotating rod 48 to lose its restraint (previously, the push rod 16 squeezed and pushed the rotating rod 48, partially retracting into the control hole 46, and the main rod 47 was pushed by the rotating rod 48 to compress the main spring 50, which, through the auxiliary spring 51, pressed the locking rod 52 into the slot 42. Part of the locking rod 52 was located in the slot 42, and part was located in the control hole 46, locking the connecting air pipe 44 in the closed groove 40). The main spring 50 pushed the main rod 47 to reset, and the reset of the main rod 47 pushed the rotating rod 48 completely out of the control hole 46. At the same time, the auxiliary spring 51 carried the locking rod 52 away from the slot 42, and the connecting air pipe 44 lost its restraint. The compressed push spring 43 pushed the outside of the closed groove 40 away (during the movement of the connecting air pipe 44, the locking rod 52, the main rod 47, and the rotating rod 48 in the control hole 46 moved synchronously, and the rotating rod 48 contacted the push rod 16 again. At this time, the rotating rod 48... Completely located outside the control hole 46, the rotating rod 48 is squeezed by the push rod 16. At this time, one end of the auxiliary spring 51 is in contact with the inner wall of the connecting air pipe 44. The main rod 47 needs to compress the main spring 50 and the auxiliary spring 51 to move, but the required force is greater than the force of the rotating rod 48 deflection. Therefore, the rotating rod 48 will deflect to one side to avoid the push rod 16 and slide past it from the outside. In this way, the push rod 16 only has a slight displacement, and the connecting air pipe 44 quickly moves out of the closed groove 40. The control hole 46 also moves to the area covered by the side plate 41. The side air hole 45 is exposed in the air supply chamber 37. The air in the air supply chamber 37 enters the connecting air pipe 44 through the side air hole 45 and is then injected into the gap created by the push rod 16 through the air supply hole 39. The air diffuses from the gap to the surroundings. The thrust provided by the air peels the lamp housing from the punch 3 and the die 4 little by little. Guided by the sliding groove 15, the push rod 16 continues to push forward. The push rod 16 pushes the lamp housing.

[0116] Step 4: As the moving distance of the ejector rod 16 increases, the ejector rods 16 on both sides clamp the lamp housing and separate it from the punch 3 and the die 4 (at this time, the ejector rod 16 reaches the maximum displacement distance, and the ejector rod 16 moves again to the end of the rotating rod 48 near the opening of the connecting air pipe 44). Then, guided by the inclined section of the sliding groove 15, the ejector rod 16 retracts a distance into the sliding insertion hole 11. The ejector rods 16 on both sides pull the lamp housing at the same time, so that the lamp housing is separated from the ejector rod 16, and the demolding is completed.

[0117] Step 5: During the second processing, clean the surfaces of the punch 3 and die 4, start the equipment, and begin mold closing. The left base plate 1 and template 2 move, increasing the gap between them and the fixed back plate 8. The outer sleeve 25 loses pressure and begins to reset. The air in the air collection groove 21 is extracted through the inner air cylinder 24. The arc-shaped sleeves 28 in both templates 2 are simultaneously affected by negative pressure, causing the arc-shaped piston rod 29 to retract. The rotating disk 12 flips, driving the ejector rod 16 to reset. The ejector rod 16 retracts into the sliding insertion hole 11, and the ejector rod 16 presses against the rotating rod 48. At this time, the locking rod 52 is unrestricted, and the movement of the main rod 47 only requires compressing the main spring 50. Therefore, the rotating rod 48 cannot deflect, but pushes the main rod 47 to move. The rotating rod 48 partially moves into the control hole 46, locking... After rod 52 contacts side plate 41, it stops moving. Push rod 16 starts to push connecting air pipe 44 into the depth of closed groove 40 through rotating rod 48. Connecting air pipe 44 moves and compresses push spring 43. When locking rod 52 enters closed groove 40 from the area covered by side plate 41, locking rod 52 is pushed into control hole 46 by inner wall of closed groove 40. Sub-spring 51 is compressed. After push rod 16 is fully reset, sliding insertion hole 11 is blocked. The surfaces of punch 3 and die 4 remain flat. Control hole 46 also moves to be flush with slot 42. The compression force of sub-spring 51 is released, pushing locking rod 52 into slot 42. Locking rod 52 restricts connecting air pipe 44 in closed groove 40. Side air hole 45 is also located in closed groove 40 and is sealed.

[0118] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
