Description

Technical Field

[0001] This utility model is a mold with a waterproof lamp hole installation component, belonging to the field of mold technology. Background Technology

[0002] In the manufacturing of outdoor electronic devices such as automotive lights, LED lighting modules, and smart terminals, waterproof sealing of lamp holes is a core technological step. These products are exposed to humid and rainy environments for extended periods, necessitating reliable sealing of the lamp holes (light source mounting holes) to prevent moisture intrusion that could lead to short circuits, optical component failure, or a sudden reduction in lifespan. This requires a sealing process with high precision and consistency, and it must be compatible with automated production lines to improve efficiency.

[0003] Most current mainstream molds use vertical injection or post-bonding processes. Existing equipment lacks a rigid positioning mechanism for the sides of the lamp hole. When the workpiece is placed, the outer edge of the lamp hole is easily misaligned with the injection port, resulting in uneven distribution of the adhesive, forming micropores or gaps, which allow water to seep in along the sides of the lamp hole.

[0004] Furthermore, traditional glue injection components only support vertical injection and cannot directly cover the side wall of the lamp hole. After the glue cools, it is easy to form a weak area on the side, resulting in poor adhesion between the sealing sheet and the workpiece and failure to meet the waterproof rating. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mold with a waterproof installation component for lamp holes, so as to solve the problems of the existing technology.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A mold with a waterproof lamp hole installation component includes: an upper module, a lower module, a workpiece placed in the middle of the lower module, a plurality of lamp holes being provided on the side of the workpiece, a positioning baffle being vertically provided above the lower module, and a vertical positioning component and a side glue injection component being provided below the upper module.

[0008] The workpiece is placed above the lower module, and the positioning baffle is attached to the outer side of the lamp hole. The upper module is attached to the lower module, and transparent glue is injected into the lamp hole through the lateral glue injection assembly and cooled to form a sealing sheet to prevent external water intrusion.

[0009] As a further improvement, the vertical positioning component includes several vertical positioning holes disposed on the workpiece, and several vertical positioning rods are disposed below the upper module. Through the cooperation of the several vertical positioning holes and the vertical positioning rods, the side glue injection component is positioned to accurately align with the lamp hole.

[0010] As a further improvement, the lateral injection assembly includes a support plate that is vertically fixedly installed below the upper module. Several injection heads are arranged on the support plate corresponding to the lamp hole positions. The multiple injection heads are connected to form a conveying channel, which is connected to an external adhesive supply assembly.

[0011] As a further improvement, the pouring head is arc-shaped and protrudes outward, forming a groove on the inner side of the sealing sheet, which fits into the subsequently installed LED beads.

[0012] As a further improvement, several sets of slots are provided inside the lamp hole near the positioning baffle, and the depth of the slots gradually increases from the inside to the outside.

[0013] As a further improvement, the vertical positioning rod includes a main rod fixedly installed with the upper module, an inner hole provided inside the lower part of the main rod, a guide groove provided on the side of the inner hole, an auxiliary rod movably inserted into the inner hole, and a protrusion provided on the side of the auxiliary rod that matches the guide groove. By the cooperation of the protrusion and the guide groove, the movement of the auxiliary rod in the inner hole is controlled. By the cooperation of the auxiliary rod and the main rod, it can adapt to the vertical positioning holes of different depths.

[0014] As a further improvement, a first magnetic sheet is embedded and fixed at the bottom of the inner hole, and a second magnetic sheet is embedded and fixed at the top of the auxiliary rod, with the first magnetic sheet and the second magnetic sheet having the same surface facing each other.

[0015] As a further improvement, the upper module includes an upper template and a conveying channel disposed in the middle above the upper template. The conveying channel is connected to the glue injection assembly, and the vertical positioning rod is fixedly installed below the upper template.

[0016] As a further improvement, the lower module includes a lower template located directly below the upper template, a positioning baffle vertically welded above the lower template, and a release layer coated on the side of the positioning baffle facing the workpiece, the release layer being in contact with the outer surface of the lamp hole.

[0017] Beneficial effects:

[0018] This utility model uses a positioning baffle vertically set in the lower module to force the outer side of the workpiece lamp hole to rigidly fit, eliminating misalignment errors caused by manual placement and ensuring absolute alignment between the lamp hole and the glue injection path.

[0019] The side-injection assembly of the upper module directly injects transparent adhesive along the side wall of the lamp hole, avoiding the blind spots of traditional vertical injection. This achieves uniform penetration and seamless adhesion of the adhesive on the hole wall, completely eliminating weak lateral areas. During use, the operator places the workpiece in the middle of the lower module, with the outer side of the lamp hole tightly against the positioning baffle for precise positioning. The upper module then presses down to adhere, with the vertical positioning assembly assisting in locking. The side-injection assembly then injects adhesive towards the lamp hole. After cooling, a highly intact seal is formed. The entire process is automated and requires no manual intervention.

[0020] Through the synergistic effect of the positioning baffle and the side injection, the sealing sheet is ensured to be bonded to the lamp hole side wall with zero gap, and the waterproof rating is stably achieved to IP68. The process is formed in one step, eliminating the traditional secondary glue filling process, reducing the failure rate from more than 15% to less than 5%, increasing the yield rate to more than 98%, and shortening the cycle by 30%.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Reference Figure 1-7 As shown, a mold with a waterproof mounting assembly for a lamp hole 11 includes:

[0033] The upper module, the lower module, and the workpiece 1 placed in the middle of the lower module. The workpiece 1 has several lamp holes 11 on its side. A positioning baffle 31 is vertically arranged above the lower module. A vertical positioning component and a side glue injection component are arranged below the upper module.

[0034] The workpiece 1 is placed above the lower module, and the outer side of the lamp hole 11 is attached to the positioning baffle 31. The upper module is attached to the lower module, and transparent glue is injected into the lamp hole 11 through the lateral glue injection assembly and cooled to form a sealing sheet 12, which is used to seal the intrusion of external water flow.

[0035] By integrating the positioning baffle 31 with the side injection assembly, the problems of positioning deviation, injection path defects and process redundancy in existing molds are precisely solved.

[0036] Specifically, the positioning baffle 31, which is vertically set in the lower module, forces the outer side of the lamp hole 11 of the workpiece 1 to be rigidly attached, eliminating the misalignment error caused by manual placement and ensuring the absolute alignment of the lamp hole 11 with the glue injection path.

[0037] The side-injection assembly of the upper module directly injects transparent adhesive along the side wall of the lamp hole 11, avoiding the blind spots of traditional vertical injection. This achieves uniform penetration and seamless adhesion of the adhesive on the hole wall, completely eliminating weak lateral areas. In use, the operator places the workpiece 1 in the middle of the lower module, with the outer side of the lamp hole 11 tightly against the positioning baffle 31 for precise positioning. Then, the upper module is pressed down to fit, and the vertical positioning assembly assists in locking. The side-injection assembly then injects adhesive towards the lamp hole 11. After cooling, a high-integrity sealing sheet 12 is formed. The entire process is automated and requires no manual intervention.

[0038] Through the synergistic effect of the positioning baffle 31 and lateral glue injection, the sealing sheet 12 and the side wall of the lamp hole 11 are ensured to be bonded with zero gap, and the waterproof rating is stably maintained at IP68. The process is formed in one step, eliminating the traditional secondary glue application step, reducing the failure rate from more than 15% to less than 5%, increasing the yield rate to more than 98%, and shortening the cycle by 30%. Compared with the existing technology, this solution breaks through the limitations of vertical glue injection, achieving directional and precise sealing of the side of the lamp hole 11, which not only eliminates the pain point of water intrusion along the side wall.

[0039] Furthermore, through structural optimization, the positioning accuracy is controlled within ±0.05mm, meeting the stringent requirements of high-end outdoor electronic equipment for highly consistent sealing, and significantly reducing manufacturing costs and quality risks.

[0040] To address the issues of positioning deviation, demolding damage, and uneven glue injection in existing molds, the upper mold assembly includes an upper template 2 and a conveying channel 21 located in the middle of the upper template 2. The conveying channel 21 connects to the glue injection assembly, and the vertical positioning rod 23 is fixedly installed below the upper template 2.

[0041] The lower module includes a lower template 3, which is located directly below the upper template 2. The positioning baffle 31 is vertically welded above the lower template 3. The positioning baffle 31 is coated with a release layer 32 on the side facing the workpiece 1. The release layer 32 is attached to the outer surface of the lamp hole 11.

[0042] The delivery channel 21 set in the middle of the upper template 2 is directly connected to the glue injection component, ensuring that the glue is stably delivered to the side glue injection port under constant pressure, avoiding pressure attenuation and uneven distribution caused by excessively long path in traditional vertical glue injection, thereby eliminating the glue coverage blind spot on the side wall of the lamp hole 11.

[0043] The vertical positioning rod 23 is fixed below the upper template 2. When the modules are attached, it is precisely inserted into the mating hole of the lower module, providing rigid constraint in the vertical direction, completely preventing the upper module from shifting, and ensuring that the positioning accuracy is controlled within ±0.05mm.

[0044] The lower template 3 is positioned directly opposite the upper template 2. The positioning baffle 31, which is vertically welded above it, adopts a high-strength welding process to ensure that there is no loosening or deformation during long-term use, and forces the outer side of the lamp hole 11 of the workpiece 1 to fit precisely.

[0045] The side of the baffle facing the workpiece 1 is coated with a release layer 32, which directly contacts the outer surface of the lamp hole 11 to form a low-friction interface. This is because the material of the release layer 32 (such as a Teflon coating) significantly reduces the adhesion force of the colloid after cooling, thus avoiding the waterproof failure caused by the tearing or residue of the sealing sheet 12 in the traditional process.

[0046] During use, the operator places the workpiece 1 in the middle of the lower template 3, and the outer side of the lamp hole 11 is tightly attached to the release layer 32 to complete self-positioning. Then, the upper module is pressed down, and the vertical positioning rod 23 locks the position simultaneously to eliminate gaps. The conveying channel 21 guides the transparent colloid to be injected into the side wall of the lamp hole 11 through the lateral injection component. After cooling, the release layer 32 allows the workpiece 1 to separate without damage. This solves the problems of sealing gaps caused by loose positioning, micropore defects caused by demolding damage, and lateral weak areas caused by vertical injection in existing equipment. It achieves zero-gap bonding of the sealing sheet 12 of the lamp hole 11, a stable waterproof rating of IP68, a failure rate reduced to below 5%, and a 30% increase in demolding efficiency, ensuring the long-term reliability of high-end outdoor electronic equipment in harsh environments.

[0047] To eliminate the vertical displacement error of workpiece 1, the vertical positioning component includes a plurality of vertical positioning holes 22 disposed on the workpiece 1, and a plurality of vertical positioning rods 23 disposed below the upper module. Through the cooperation of the plurality of vertical positioning holes 22 and the vertical positioning rods 23, the side glue injection component is positioned to accurately align with the lamp hole 11.

[0048] The pre-set vertical positioning hole 22 on the workpiece 1 forms a high-precision engagement with the positioning rod below the upper module. This is because traditional molds lack vertical constraints, and the workpiece 1 is prone to micron-level displacement when it is under pressure, which causes the lamp hole 11 to be misaligned with the glue injection port, resulting in uneven glue distribution and sealing gaps.

[0049] The positioning accuracy is stably controlled within ±0.03mm to ensure that the lateral glue injection assembly is absolutely aligned with the lamp hole 11, and to avoid the glue forming a blind spot or weak area on the hole wall.

[0050] When in use, the operator places workpiece 1 in the lower module and aligns its positioning hole with the positioning rod of the upper module.

[0051] During mold closing, the positioning rod is precisely inserted into the hole, forcibly calibrating the position of workpiece 1, so that the lateral glue injection assembly is directly aligned with the inlet of lamp hole 11. This solves the glue injection deviation problem caused by the vertical offset of workpiece 1, completely eliminates micropore defects caused by misalignment, and ensures seamless fit between sealing plate 12 and the side wall of lamp hole 11.

[0052] The side-mounted adhesive assembly includes a support plate 24 that is vertically fixedly installed below the upper module. Several pouring heads 25 are arranged on the support plate 24 corresponding to the lamp hole 11. The multiple pouring heads 25 are connected to form a conveying channel 21, which is connected to an external adhesive supply assembly.

[0053] The pouring head 25 has an arc-shaped protrusion 26 facing outward, forming a groove 13 on the inner side of the sealing sheet 12, which fits into the subsequently installed lamp beads.

[0054] The vertical fixation of the support plate 24 ensures that the position of the pouring head 25 is absolutely stable. This is because the traditional side-injection assembly has a loose structure, which causes the lamp hole 11 to shift, resulting in uneven distribution of the adhesive and micropore defects.

[0055] The pouring head 25 is precisely positioned to correspond to the lamp hole 11 and connected to the external supply system through the delivery channel 21, enabling multi-point synchronous glue injection. This eliminates pressure fluctuations caused by path differences and ensures that the glue evenly penetrates the entire sidewall of the lamp hole 11. The arc-shaped protrusion 26 of the pouring head 25 facing outwards is designed to directly match the contour of the lamp bead, so that the inner side of the sealing sheet 12 naturally forms a groove 13 after cooling. This is because in the existing process, there is an assembly gap between the flat sealing sheet 12 and the lamp bead, which easily leads to moisture intrusion along the interface. The groove 13 structure provides mechanical locking force, significantly enhancing the bonding strength.

[0056] In this embodiment, six dispensing heads are provided. In other embodiments, the design is based on the needs of workpiece 1.

[0057] In use, the external colloid supply component delivers transparent colloid at constant pressure to each pouring head 25 through the delivery channel 21. After the operator closes the mold, the colloid is precisely injected into the side wall of the lamp hole 11 through the arc-shaped protrusion 26, and cools and solidifies to form a sealing sheet 12 with a groove 13. When installing the lamp beads, its outer edge is directly embedded in the groove 13 to achieve a seamless fit.

[0058] It solves the problem of lateral weak areas caused by incomplete coverage in traditional glue injection, improves the interface bonding force between the sealing sheet 12 and the LED bead by 40%, completely eliminates the risk of leakage caused by assembly gaps, reduces the waterproof failure rate to below 1%, and ensures that outdoor electronic devices maintain IP68 sealing performance for a long time under vibration or temperature change environment.

[0059] The lamp hole 11 has several sets of slots 27 on the side near the positioning baffle 31, and the depth of the slots 27 gradually increases from the inside to the outside.

[0060] The slot 27 inside the lamp hole 11, located near the positioning baffle 31, features a depth that gradually changes from the inside to the outside. This design aims to enhance the mechanical interlocking force between the sealing plate 12 and the workpiece 1. Traditional lamp holes 11 have a smooth inner wall, where the sealant relies solely on surface adhesion after injection. Over long-term use, this can lead to interface peeling due to thermal expansion and contraction or vibration, causing water leakage. The gradual depth design of the slot 27 creates a gradient-distributed anchoring structure during the filling process. The amount of sealant increases towards the outer edge, resulting in a gradually increasing stress-locking effect after cooling, significantly improving the shear and peel resistance of the sealing plate 12.

[0061] In use, workpiece 1 is placed on the lower module, and the positioning baffle 31 is attached to the outer side of the lamp hole 11 to complete the positioning. During the glue injection process, the glue is injected through the side pouring head 25, simultaneously filling the side wall of the lamp hole 11 and the internal slot 27. As the depth of the slot 27 increases outward, the glue forms a core with increased volume at the end of the flow. After cooling, it forms a multi-level inverted structure with the slot wall, effectively preventing moisture from penetrating along the inner wall of the lamp hole 11. This structure solves the problems of easy detachment and poor durability of the sealing sheet 12 in traditional processes, allowing the sealing layer to maintain its integrity under temperature change cycles from -40℃ to 120℃, and extending the waterproof life to more than 5 years. It is suitable for automotive lamps and outdoor lighting modules in high vibration and high humidity environments. Compared with the conventional straight hole structure, the interface bonding strength is increased by 50%, eliminating gradual leakage failure during long-term service.

[0062] To address the positioning failure caused by the thickness difference of workpiece 1, the vertical positioning rod 23 includes a main rod 231 fixedly installed with the upper module, an inner hole 232 inside the lower part of the main rod 231, a guide groove 233 on the side of the inner hole 232, an auxiliary rod 234 movably inserted into the inner hole 232, and a protrusion 237 on the side of the auxiliary rod 234 that matches the guide groove 233. By cooperating with the guide groove 233, the auxiliary rod 234 is controlled to move within the inner hole 232. By cooperating with the main rod 231, the auxiliary rod can adapt to the vertical positioning holes 22 of different depths.

[0063] A first magnetic sheet 235 is embedded and fixed at the bottom of the inner hole 232, and a second magnetic sheet 236 is embedded and fixed at the top of the auxiliary rod 234. The first magnetic sheet 235 and the second magnetic sheet 236 are arranged with their same surface facing each other.

[0064] Traditional fixed positioning rods cannot adapt to the varying depths of the vertical positioning holes 22 on different workpieces 1, which can easily lead to positioning deviations or mold damage.

[0065] The inner hole 232 of the main rod 231 is provided with a guide groove 233 that cooperates with the protrusion 237 of the auxiliary rod 234, forcing the auxiliary rod 234 to move only in a straight line along the axial direction, eliminating the risk of rotational offset, and stably controlling the positioning accuracy within ±0.02mm. Magnets of the same level (e.g., N pole to N pole) are embedded at the bottom of the inner hole 232 and the top of the auxiliary rod 234, generating a constant repulsive force. This is because the magnetic mechanism provides elastic buffering.

[0066] When the mold closes, the auxiliary rod 234 is pressed and moves smoothly down along the guide groove 233 to avoid deformation of the workpiece 1 or wear of the positioning hole caused by impact; after the mold opens, the auxiliary rod 234 is automatically reset by magnetic force to ensure rapid response and continuous production.

[0067] When in use, the operator places the workpiece 1 in the lower module, and the outer side of the lamp hole 11 is in close contact with the positioning baffle 31 to complete the initial positioning; during the pressing down of the upper module, the main rod 231 first contacts the surface of the workpiece 1, and the auxiliary rod 234 extends into the vertical positioning hole 22 simultaneously under the magnetic buffer, and the protrusion 237 slides along the guide groove 233 to calibrate the depth.

[0068] After the glue injection is completed and the mold is opened, the magnetic sheet repulsion force and its own gravity immediately push the auxiliary rod 234 back to the standby position. This solves the positioning misalignment problem caused by the thickness tolerance of workpiece 1, completely eliminates the micron-level gap caused by hard contact, and makes the alignment error between the side glue injection assembly and the lamp hole 11 approach zero.
