Description

Technical Field

[0001] The utility model relates to the technical field of machining, and more specifically, the utility model relates to a packaging mold with an angle. Background Art

[0002] The packaging mold is a key tool used in the process of electronic component packaging. Its main functions include: protecting electronic components: packaging can prevent electronic components from being damaged by the external environment, such as oxidation, corrosion, and physical damage; connecting and fixing: packaging fixes the electronic components in specific positions and connects them to other electronic components or circuit boards through pins, solder joints, etc.; heat dissipation and isolation: the packaging material usually has good thermal conductivity, which helps to dissipate the heat generated by the electronic components during operation, and at the same time isolates the electromagnetic interference between different electronic components.

[0003] The principle of packaging LED beads is mainly to isolate the LED chip from the external environment through the packaging material to protect the chip from adverse factors such as mechanical damage, chemical corrosion, and moisture. At the same time, the packaging material can also improve the heat dissipation performance of the LED beads to ensure that the chip will not be damaged due to overheating during high-power operation. In addition, the packaging process also involves optical design to ensure that the light emitted by the LED beads can propagate at a predetermined angle and direction, so as to achieve the best lighting effect.

[0004] There are three modes for the luminous angle of conventional packaged LED beads:

[0005] First, for through-hole LEDs, it is generally controlled by the combination of the mold bar and the bracket. Generally speaking, the deeper the bracket cup, the smaller the angle. The mold bar is also divided into a spotlight mold bar and a large-angle mold bar. For example, the angle of a 5mm bullet head mold bar is definitely smaller than that of a 5mm straw hat head.

[0006] Second, for power-type LEDs, this is generally determined by the bracket, lens, or injection mold.

[0007] Third, for surface-mount LEDs, the angle of surface-mount LEDs is relatively special. Generally, the angle is determined by the bracket. The angles of 3528 and 5050 are different, and there are not many places for adjustment. Whatever the angle is, it will be like that. Maybe only when dispensing glue can it be controlled. If the glue is less, the angle will be a little larger. If the glue is more, the angle will be a little smaller, but it is not obvious.

[0008] Currently, the above three modes will have certain impacts when used: among them, determining the angle by the depth or the mouth of the bracket cup, or determining the angle by the bracket results in fewer angle selections and higher costs. Moreover, the angle consistency will be poor due to the tolerance of the materials. Content of the Utility Model

[0009] A packaging mold with an angle provided by the present utility model aims to solve the following problems: In existing packaging molds, the angle is determined by the depth or the opening of the bracket cup, or by the bracket, resulting in few angle options, high costs, and poor angle consistency due to the tolerance of the materials.

[0010] To achieve the above object, the present utility model provides the following technical solutions: A packaging mold with an angle includes a base and a mold body. The base is used to carry the mold body, and a connecting member is provided between the base and the mold body. The connecting member is used to fix the mold body on the base. The connecting member includes positioning screw pipes. Two groups of positioning screw pipes are symmetrically arranged. The positioning screw pipes are fixedly installed in the inner cavity of the base. A positioning screw is threadedly connected inside the positioning screw pipe. The mold body is connected to the base through the positioning screw. The connecting member includes a cross plate. The cross plate is slidably connected to the base. A convex block is provided on the side of the cross plate. When the cross plate is parallel to the mold body, the convex block is clamped with the mold body, thereby fixing the mold body and the base.

[0011] In a preferred embodiment, the connecting member further includes cavities symmetrically opened on both sides of the base. The cross plate is slidably arranged inside the cavities. A plurality of holes are opened on the surface of the cross plate. The convex block is slidably arranged inside the holes. A spring is provided between the convex block and the holes. Corresponding clamping holes are opened on both side surfaces of the mold body for each convex block. The convex block is clamped with the clamping hole.

[0012] In a preferred embodiment, push plates corresponding to the cross plate are provided on both sides of the base. The push plates are fixedly connected to the cross plate. Connecting plates are provided above and below the push plates on both sides of the base. Magnetic attraction plates are provided on the opposite surfaces of the push plates and the connecting plates. The push plates and the connecting plates are magnetically attracted and connected through the magnetic attraction plates.

[0013] In a preferred embodiment, a support plate is fixedly provided on one side of the base. A pushing member is rotatably connected to the support plate. The pushing member is used to push on the mold body. The pushing member includes a rotating plate. The rotating plate is rotatably connected to the support plate. A long plate is provided on the side of the rotating plate close to the mold body. The size of the long plate is the same as the size of the mold body. A rotating rod is provided on the side of the rotating plate away from the mold body. An expansion rod is connected between the rotating rod and the long plate. The expansion rod is fixedly connected to the long plate.

[0014] In a preferred embodiment, upper grooves are provided on both sides of the mold body, and lower grooves matching the upper grooves are provided on the base.

[0015] In a preferred embodiment, the mold body includes a plurality of ball heads. The ball heads are of a structure with an open upper end and an arc-shaped lower end, and are located inside the base.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The utility model fixes the position of the push plate by setting a connecting piece to push the push plate to contact the connecting plate above and connecting through a magnetic attraction plate, making the cross plate parallel to the mold body. The elastic force of the spring is used to push the convex block into the clamping hole on the surface of the mold body to fix the mold body and the base. Moving the position of the cross plate to separate the convex block from the mold body can release the fixation of the mold body, facilitating the disassembly and fixation of the mold body.

[0018] 2. The utility model sets a pushing piece to make the rotating plate contact the mold body. Rotating the rotating rod drives the telescopic rod and the long plate to move, pushing the surface of the mold body, which can not only remove excess glue but also remove residues on the mold body, reducing the number of manual cleaning times.

[0019] 3. The utility model connects the mold body and the base, and pours glue into the mold body. The light-emitting angle of the lamp bead is changed by a hydraulic method. In terms of function: the consistency of the ball head angle can be controlled within ±3°, and the light-emitting shape can be well controlled. In terms of versatility: usually, only one conventional lens can be made at a time, but now it can be matched according to the number of mold bodies. For example, if there are 1000 PCS of mold bodies, it can be formed at one time, increasing the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Referring to the attached Figure 1 - Figure 5 , an encapsulation mold with an angle, including a base 1 and a mold body 2. The base 1 is used to carry the mold body 2, and a connecting member 3 is provided between the base 1 and the mold body 2. The connecting member 3 is used to fix the mold body 2 on the base 1; the connecting member 3 includes a positioning screw tube 310. Two groups of positioning screw tubes 310 are symmetrically arranged. The positioning screw tubes 310 are fixedly installed in the inner cavity of the base 1. A positioning screw is threadedly connected inside the positioning screw tube 310. The mold body 2 is connected to the base 1 through the positioning screw; the connecting member 3 includes a cross plate 320. The cross plate 320 is slidably connected to the base 1. A convex block 321 is provided on the side surface of the cross plate 320. When the cross plate 320 is parallel to the mold body 2, the convex block 321 is clamped with the mold body 2, thereby fixing the mold body 2 and the base 1.

[0028] It should be noted that there are two connection methods between the base 1 and the mold body 2. The base 1 is connected to the positioning screw tube 310 through a positioning screw; the mold body 2 is connected to the convex block 321 by moving the position of the cross plate 320.

[0029] Further, the connecting member 3 further includes cavities symmetrically opened on both sides of the base 1. The cross plate 320 is slidably arranged inside the cavities. A plurality of holes are opened on the surface of the cross plate 320. The convex block 321 is slidably arranged inside the holes. A spring 322 is provided between the convex block 321 and the holes; corresponding clamping holes are opened on both side surfaces of the mold body 2 that correspond to the convex blocks 321 one by one, and the convex blocks 321 are clamped with the clamping holes.

[0030] It should be noted that since the convex block 321 is a trapezoidal structure, when the cross plate 320 moves upward or downward, the convex block 321 retracts into the holes along the inner wall of the base 1, making the spring 322 in a contracted state. Therefore, when the cross plate 320 moves, the spring 322 can automatically contract without affecting the cross plate 320.

[0031] Further, push plates 323 corresponding to the cross plate 320 are provided on both sides of the base 1. The push plates 323 are fixedly connected to the cross plate 320. Connecting plates 324 are provided above and below the push plates 323 on both sides of the base 1. Magnetic attraction plates 325 are provided on the opposite surfaces of the push plates 323 and the connecting plates 324. The push plates 323 and the connecting plates 324 are magnetically connected through the magnetic attraction plates 325.

[0032] It should be noted that since the magnetic attraction force between the connecting plate 324 and the magnetic attraction plate 325 on the pushing plate 323 is greater than the weight of the pushing plate 323 and the cross plate 320, when the pushing plate 323 contacts the upper connecting plate 324, it is magnetically connected through the magnetic attraction plate 325, and the cross plate 320 is fixed parallel to the mold body 2, further increasing the stability of the cross plate 320.

[0033] Furthermore, referring to the attached drawings of the specification Figure 2 With Figure 5 , a support plate 4 is fixedly provided on one side of the base 1, and a pushing member 5 is rotatably connected to the support plate 4. The pushing member 5 is used to push on the mold body 2; the pushing member 5 includes a rotating plate 51, the rotating plate 51 is rotatably connected to the support plate 4, a long plate 52 is provided on the side of the rotating plate 51 close to the mold body 2, the size of the long plate 52 is the same as the size of the mold body 2, a rotating rod 53 is provided on the side of the rotating plate 51 away from the mold body 2, and a telescopic rod 54 is connected between the rotating rod 53 and the long plate 52, and the telescopic rod 54 is fixedly connected to the long plate 52.

[0034] It should be noted that by pushing the long plate 52 to rotate along the rotating plate 51 to make the long plate 52 contact the surface of the base 1, and rotating the rotating rod 53 to extend the telescopic rod 54 connected to the long plate 52, the long plate 52 is moved along the surface of the mold body 2. This can not only push the glue on the mold body 2 flat to discharge the excess glue, but also remove the residual solids after demolding, which is convenient for subsequent use and reduces manual cleaning; after use, the rotating plate 51 is rotated to a state perpendicular to the base 1, which will not affect the use of the mold body 2.

[0035] Furthermore, referring to the attached drawings of the specification Figure 1 With Figure 2 , upper grooves 6 are provided on both sides of the mold body 2, and lower grooves 7 matching the upper grooves 6 are provided on the base 1.

[0036] It should be noted that after placing the mold body 2 on the base 1, the upper grooves 6 and the lower grooves 7 are clamped to limit the mold body 2 and prevent the mold body 2 from shifting.

[0037] Furthermore, referring to the attached drawings of the specification Figure 1 , the mold body 2 includes ball heads 8. The ball heads 8 are provided in multiple groups. The ball heads 8 have a structure with an open upper end, and the lower ends of the ball heads 8 are arc-shaped structures and are located inside the base 1.

[0038] It should be noted that after pouring glue into the ball heads 8 on the base 1, the glue is formed into lamp beads by a hydraulic method to fit the shape of the ball heads 8, and the light-emitting angle of the lamp beads can be changed; since the angle consistency of the ball heads 8 can be controlled within ±3°, the light-emitting shape can be well controlled.

[0039] Working principle: First, place the mold body 2 on the base 1 so that the upper groove 6 on the mold body 2 engages with the lower groove 7 on the base 1 to limit the position of the mold body 2.

[0040] There are two methods to fix the mold body 2 and the base 1: (1) Place the positioning screw from the bottom of the base 1 inside the positioning screw tube 310 and thread it with the positioning screw tube 310 to connect the mold body 2 and the base 1.

[0041] (2) Move the push plate 323 to separate from the magnetic attraction plate 325 on the lower connecting plate 324, so that the cross plate 320 slides along the cavity on the base 1, and magnetically connect the push plate 323 with the magnetic attraction plate 325 on the upper connecting plate 324 to make the cross plate 320 flush with the mold body 2; when the cross plate 320 moves, the convex block 321 retracts inside the hole, the spring 322 is in a compressed state, and the end of the convex block 321 is in contact with the inner wall of the cavity. When the cross plate 320 is parallel to the mold body 2, the elasticity of the spring 322 pushes the convex block 321 to move, so that the convex block 321 is engaged with the clamping hole on the surface of the mold body 2 to connect the mold body 2 and the base 1.

[0042] Then, pour glue into the ball head 8 on the base 1, make lamp beads by hydraulic means. After demolding the lamp beads, contact the rotating plate 51 with the base 1 by rotation, and then rotate the rotating rod 53 to extend the telescopic rod 54, and push the long plate 52 along the mold body 2, so as to remove the residue on the mold body 2, which is convenient for subsequent use and reduces the number of manual cleaning times.

[0043] The utility model connects the convex block 321 with the mold body 2 by moving the position of the cross plate 320, connects the mold body 2 and the base 1, and then connects the push plate 323 and the connecting plate 324 through the magnetic attraction plate 325 to fix the cross plate 320 in a position parallel to the mold body 2, which can increase the connection stability between the convex block 321 and the mold body 2; by moving the position of the rotating plate 51 and then rotating the rotating rod 53 to drive the telescopic rod 54 to contact the long plate 52 with the mold body 2, the mold body 2 can be cleaned.

[0044] The above embodiments only represent several implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
