[0002] In the composition of lighting fixtures, lampshades are a very common auxiliary structure that can effectively concentrate and reflect the light of the lighting fixture, and also play a role in wrapping and protecting the lighting fixture. At present, lighting lampshades are mainly produced in the form of injection molding. Thanks to the injection molding process, lampshade production has become very convenient and quick.

[0003] During the injection molding process, the lampshade mold needs to be aligned with the discharge port of the extruder. In the conventional injection molding process, the injection mold of the lampshade is docked with the discharge port. In order to facilitate demoulding, half of the mold is often fixed to the discharge port, and the other half of the mold is movable. This results in residual burrs often appearing on the inside of the mold after demoulding during use of the lighting lampshade mold. At present, this situation is usually avoided by applying a release agent. However, both the current release agent application and demoulding require a certain amount of operation time, so the injection molding efficiency of the lampshade is low. In view of this, an in-depth study was conducted on the above-mentioned problem, which led to the creation of this case. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 The present invention provides an implementation scheme: In the modern lampshade production process, in order to facilitate the processing of the lampshade, injection molding is often used for processing. At present, the mold for the lampshade injection molding is mostly divided into two parts. Specifically, the movable mold 3 and the fixed mold can be closed, and the gap between the molds is used as the injection molding space of the lampshade. However, this injection molding method requires the release agent to be applied after the material is unloaded, which is cumbersome and inefficient.

[0021] According to the instruction manual Figure 1-3 It can be seen that in response to the above problems, the present application discloses a lighting lampshade injection molding device. In a specific implementation process, the device is connected to an injection molding machine through an injection molding outlet 1. The injection molding channel of the injection molding machine extrude plastic, and then a base mold 2 is connected to one side of the injection molding outlet 1 through a flange. A movable mold 3 is correspondingly provided on one side of the base mold 2. The base mold 2 and the movable mold 3 are arranged relative to each other. A mold sliding structure is connected between the movable mold 3 and the base mold 2. The mold sliding structure can drive the movable mold 3 to move forward, thereby driving the movable mold 3 to operate. By switching the workstations of the movable mold 3 and cooperating with a release agent coating device, the mold can be fully automatically demolded and coated with a release agent.

[0022] According to the instruction manual Figure 1-3 As can be seen, the mold sliding structure includes a rolling bracket 4, which is assembled on one side of the injection outlet 1. The rolling bracket 4 is provided with an indexing assembly 5. The driving end of the indexing assembly 5 is connected to an indexing turntable 6. The outer peripheral wall of the indexing turntable 6 is provided with a plurality of mounting positions 7, and the plurality of mounting positions 7 are respectively equipped with a plurality of retractable mold clamps 8;

[0023] In the specific implementation process, the rolling bracket 4 can support and limit the indexing turntable 6, and the indexing turntable 6 is driven by the indexing assembly 5 to rotate, so that the several mounting positions 7 on the indexing turntable 6 rotate. Several clamping devices 8 are provided at the several mounting positions 7 on the indexing turntable 6. The several clamping devices 8 can be used to adjust the several movable molds 3 to be telescopic, thereby realizing the buckling and opening of the movable mold 3 and the fixed mold. After the separation of the movable mold 3 is completed, rapid unloading and coating are carried out;

[0024] According to the instruction manual Figure 1-3It can be seen that the above-mentioned mold clamper 8 is connected to the movable mold 3, and a release agent coating tube 9 is provided on one side of the rolling bracket 4, and at least one coating nozzle 10 is provided on the end of the release agent coating tube 9. During the implementation process, the base mold 2 corresponds to one of the mounting positions 7. During injection molding, the base mold 2 corresponds to one of the mounting positions 7, and the movable mold 3 is pushed to press the base mold 2 through the mold clamper 8. After the injection molding is completed, the mold clamper 8 separates the movable mold 3 from the base mold 2. The coating nozzle 10 corresponds to the previous mounting position 7 of the base mold 2, and a discharge port 11 is provided on one side corresponding to the next mounting position 7 of the base mold 2. When the movable mold 3 is separated from the base mold 2, the injection molded part in the movable mold 3 is separated from the movable mold 3 at the discharge port 11 position, and then the movable mold 3 on the next mounting position 7 is coated with the release agent. The release agent coating utilizes the release agent coating tube 9 on the corresponding mounting position 7 to push the release agent to the coating nozzle 10, and then the coating nozzle 10 is used to coat the inside of the movable mold 3.

[0025] As a preferred solution, further, the indexing assembly 5 is driven by a indexing motor, and is connected to the driving end of the indexing motor with an intermittent groove wheel and a indexing turntable 6 that cooperates with the intermittent groove wheel. The indexing motor controls the rotation of the intermittent groove wheel, so that the intermittent groove wheel drives the indexing turntable 6 to rotate, and then the indexing turntable 6 drives the mounting position 7 thereon to rotate according to the indexing angle, so that the movable turntable on the mounting position 7 circulates between the coating nozzle 10, the base mold 2 and the discharge port 11, completing the release agent coating, molding and demolding operation steps of the injection molding process.

[0026] As a preferred solution, further, the number of the plurality of mounting positions 7 is at least three, and the number of the movable molds 3 and the mold clamps 8 corresponds to each other.

[0027] As a preferred solution, further, the rolling bracket 4 is a rectangular frame, and both ends of the indexing turntable 6 are movably assembled on the rolling bracket 4, which has a simple structure and is easy to produce.

[0028] As a preferred solution, further, a control valve 12 is provided on the release agent coating tube 9, and an angle adjuster 13 is provided on the coating nozzle 10. The angle adjuster 13 is used to adjust the angle of the coating nozzle 10.
