Technical Field

[0001] This utility model relates to the field of lighting mold technology, and in particular to a lampshade face ring mold structure. Background Technology

[0002] like Figure 1 and Figure 2 The image shows lampshade face rings of different sizes and structures. The overall structure is a rectangular ring, including a ring-shaped face frame plate. One side of the face frame plate has a ring-shaped raised edge plate. Multiple snap-fit ​​protrusions are spaced apart on the inner circumference of the raised edge plate. One or more snap-fit ​​cylinders with a rectangular cylindrical structure are provided on the two outer sides of the raised edge plate. A rectangular through hole is provided between the inner end of the snap-fit ​​outer wall and the surface of the face frame plate. Rectangular openings are provided on the snap-fit ​​outer wall at intervals from the through hole.

[0003] The aforementioned lampshade rings are typically manufactured using injection molding with different molds. However, the existing mold design has the following drawbacks: 1. It is inconvenient to use the same mold to injection mold lampshade rings of different structural sizes, resulting in different molds being required for lampshade rings of different sizes, which increases mold costs; 2. The design of the core-pulling part of the mold used to form the snap-fit ​​sleeve on the lampshade ring is not reasonable enough, resulting in a complex mold structure design and inconvenience in the layout of the core-pulling part on the side of the mold.

[0004] Therefore, how to design a lampshade face ring mold structure with a simpler and more reasonable structure that can better form lampshade face rings of different sizes, and with a simpler and more convenient layout design for the side core pulling part, has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design a lampshade face ring mold structure with a simpler and more reasonable structural design, which can better form lampshade face rings of different sizes, and with a simpler and more convenient layout design for the side core pulling part.

[0006] To achieve the above objectives, this utility model provides a lampshade face ring mold structure, including a moving mold part structure and a fixed mold part structure; the moving mold part structure includes a moving template, and the fixed mold part structure includes a fixed template, with a moving mold and a fixed mold respectively provided on the moving template and the fixed template; a face ring forming cavity is formed between the moving mold and the fixed mold for forming the face ring; characterized in that; the face ring forming cavity includes a first face ring forming cavity, a mating cavity is formed by an overall downward recess at the middle position of the inner side of the first face ring forming cavity on the surface of the fixed mold, and a mating core is formed by a protrusion on the moving mold at a position opposite to the mating cavity; the face ring forming cavity includes a second face ring forming cavity disposed between the bottom surface of the mating cavity and the surface of the mating core; and the first face ring forming cavity and the second face ring forming cavity are respectively used to form the first face ring and the second face ring, and the size of the first face ring is set to be larger than the size of the second face ring.

[0007] Thus, the lampshade ring mold structure described above includes a first ring forming cavity and a second ring forming cavity, enabling the formation of first and second rings of different sizes using the same mold, thereby reducing mold costs. The first and second ring forming cavities are located on different planes, facilitating easier processing and forming. The nested arrangement of the first and second ring forming cavities results in a more rational layout and a more compact overall structural design.

[0008] As an optimization, a side core-pulling drive slider is provided on the fixed template; a slider drive structure is provided on the moving template to drive the side core-pulling drive slider to move horizontally outward; a first forming core block is provided at each of the two inner ends of the side core-pulling drive slider, and the inner end of the first forming core block passes through the first clearance opening on the fixed mold and extends into the first annular forming cavity, so that the inner end of the first forming core block is used to form the through hole and opening structure on the first annular retaining cylinder; a second forming core block is provided at the middle position of the inner side of the side core-pulling drive slider, and the inner end of the second forming core block passes through the second clearance opening on the fixed mold and extends into the second annular forming cavity, so that the inner end of the second forming core block is used to form the through hole and opening structure on the second annular retaining cylinder.

The whole structure design is simpler, the layout design is more convenient, and components are saved.

[0010] As an optimization, a rectangular mating groove is provided on the fixed template, and the side core-pulling drive slider is provided in the mating groove. The lower sides of both ends of the side core-pulling drive slider protrude outward to form guide sliders, and the guide sliders are slidably fitted in the guide grooves on the inner ends of the two side walls of the mating groove.

[0011] This makes it easier to install and arrange the side core-pulling drive slider, and also allows for better guidance.

[0012] As an optimization, the side core-pulling drive slider includes a mounting block with a rectangular plate structure, a connecting hole on the mounting block, and the outer ends of the first and second molding core blocks are respectively inserted into the connecting hole. It also includes a fixing block that is attached to the outside of the mounting block, and the connecting block and the fixing block are fixed together by screws.

[0015] In this way, the slider drive structure adopts an inclined slider drive rod that cooperates with the side pull drive hole, making the overall structure design simpler and the side pull drive more stable and reliable.

[0016] Furthermore, the slider drive rods are arranged in pairs, and the corresponding side pull drive holes are also arranged in pairs.

[0017] As an optimization, the upper end face of the side core-pulling drive slider extends above the upper end face of the fixed mold; a rectangular insertion hole is provided on the moving mold plate and on the upper end of each corresponding side core-pulling drive slider; and a chamfered structure is provided on the outer side of the upper end of the side core-pulling drive slider to form a mating slope, and a driving slope is provided on the side wall of the insertion hole and on the corresponding mating slope.

[0018] In this way, the upper end of the side core-pulling drive slider is provided with a mating slope. When the mold is closed, the mating slope can cooperate with the driving slope on the moving platen, so that the side core-pulling drive slider can be better reset after the mold is closed and the positional accuracy is higher.

[0019] As an optimization, the fixed mold has a core hole and a forming core in the snap-fit ​​cylinder corresponding to the first and second rings, and the upper end of the forming core extends into the snap-fit ​​cylinder.

[0020] In this way, the snap-fit ​​sleeves on the first and second rings of the molding core make it easier to replace and reduce the cost of using the mold.

[0021] As an optimization, two annular forming cavities are provided in pairs between the moving mold and the fixed mold.

[0022] This configuration, which involves creating two parts per mold, improves molding efficiency.

[0023] As an optimization, rectangular blind holes are provided on both the fixed template and the moving template, and each hole is used to install the fixed template and the moving template.

[0024] This makes it easier to install and fix the moving mold and the fixed mold.

[0025] In summary, the above structure features a simpler and more reasonable structural design, better ability to form lampshade rings of different sizes, and a simpler and more convenient layout design for the side core-pulling part. Attached Figure Description
