Description

Technical Field

[0001] The utility model belongs to the technical field of lighting production, and particularly relates to a mold for producing lamp shades. Background Technique

[0002] A pulp lamp shade is a lamp shade made of pulp material. Pulp is made by soaking paper in water, then stirring it into a paste, and then through processes such as extrusion and drying. This material can be shaped into various shapes, including lamp shades. Pulp lamp shades usually have unique textures and qualities, and can add a touch of natural and warm atmosphere to the indoor space.

[0003] The outer mold of the existing pulp lamp shade mold is usually fixed on an iron plate and cannot be disassembled. When lamp shades of different sizes need to be produced, it is very cumbersome to customize corresponding mold equipment, which not only increases the funds required for lamp shade production, but also reduces the practicality of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a mold for producing lamp shades. By setting a replacement component, the device can customize lamp shades of different sizes by replacing different types of outer molds, solving the problem that the outer mold of the existing pulp lamp shade mold is usually fixed on an iron plate and cannot be disassembled. When lamp shades of different sizes need to be produced, it is very cumbersome to customize corresponding mold equipment, which not only increases the funds required for lamp shade production, but also reduces the practicality of the device.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a mold for producing lamp shades, including an iron plate. A first groove is opened at the top of the iron plate. A fixed seat is in contact with the inner wall of the first groove. An outer mold is fixedly connected to the top of the fixed seat. An injection product is in contact with the outer surface of the outer mold. An inner mold is fixedly connected to the inner wall of the outer mold. A fixed frame is fixedly connected to the bottom of the iron plate. A replacement component is arranged inside the iron plate. A demolding component is arranged at the bottom of the iron plate. The replacement component includes threaded rods. The number of threaded rods is two. A pulley is fixedly connected to the back of each of the two threaded rods. A belt is in transmission connection with the outer surfaces of the two pulleys. A turning handle is fixedly connected to the front of the threaded rod on the left. Two first square grooves are opened at the top of the iron plate. By setting the replacement component, the fixed seat and the outer mold can be removed and a new outer mold can be replaced, enabling the same mold equipment to produce lamp shades of different sizes and improving the practicality of the device.

[0007] Furthermore, the two square grooves 1 are symmetrically arranged with the center of the iron plate as the symmetry axis. The parts contained inside the two square grooves 1 are the same. A clamping block is slidably connected to the inner wall of the square groove 1. The number of the clamping blocks is two. By setting the clamping blocks, the staff can quickly and conveniently replace the outer mold.

[0008] A circular groove 1 is opened inside each of the two clamping blocks. The inner walls of the two circular grooves 1 are both threadedly connected to the outer surface of the threaded rod. One side of the two clamping blocks that is close to each other is in contact. The bottoms of the two clamping blocks are both in contact with the top of the fixed seat. By setting the fixed seat, the stability of the outer mold of the device during operation is improved.

[0009] Furthermore, the demoulding assembly includes a motor. The bottom of the fixed frame is fixedly connected to the top of the motor. The output end of the top of the motor is fixedly connected to a rotating rod. A circular groove 2 is opened at the bottom of the iron plate. The inner wall of the circular groove 2 is rotatably connected to the top of the rotating rod. By setting the demoulding assembly, the outer mold vibrates to quickly demould the solidified lampshade on the surface of the outer mold, reducing the tediousness of the staff during demoulding and improving the production efficiency of the device.

[0010] Furthermore, a rotating block is fixedly connected to the outer surface of the rotating rod. The top of the rotating block is in contact with the bottom of the iron plate. A rotating shaft is fixedly connected to the bottom of the iron plate. The number of the rotating shafts is two. By setting the rotating block, the vibration frequency of the device for the outer mold is increased.

[0011] Furthermore, vibration blocks are rotatably connected to the outer surfaces of the two rotating shafts. A spring is fixedly connected to one side of the two vibration blocks that is close to each other. By setting the spring, the two vibration blocks can return to their original positions when not subjected to the thrust of the rotating block.

[0012] Furthermore, one side of the two vibration blocks that is close to each other is in contact with the outer surface of the rotating block. Two square grooves 2 are opened inside the iron plate. The inner walls of the two square grooves 2 are both in contact with insertion plates. The tops of the two insertion plates are both fixedly connected to the bottom of the fixed seat. By setting the vibration blocks, the production efficiency of the device is improved.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting the replacement assembly, specifically, rotating the handle counterclockwise drives the threaded rod to rotate. When the two threaded rods rotate, they drive the two clamping blocks to move away from each other and no longer restrict the top of the fixed seat. Thus, the fixed seat and the outer mold can be removed and a new outer mold can be replaced, enabling the same mold device to produce lampshades of different sizes and improving the practicability of the device.

[0015] 2. The utility model is provided with a demoulding assembly. Specifically, the motor is turned on to drive the rotating block to rotate, so that the surface of the vibrating block insertion plate contacts and impacts to generate vibration. When the rotating block continues to rotate, the two vibrating blocks repeatedly move back and forth, causing the outer mold to vibrate and quickly demould the solidified lampshade on the surface of the outer mold, reducing the tediousness of the staff during demoulding and improving the production efficiency of the device.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1-7 As shown, this utility model is a mold for producing lamp shades, including an iron plate 1. A first groove is opened at the top of the iron plate 1. A fixed seat 2 is in contact with the inner wall of the first groove. An outer mold 5 is fixedly connected to the top of the fixed seat 2. An injection molded product 3 is in contact with the outer surface of the outer mold 5. An inner mold 6 is fixedly connected to the inner wall of the outer mold 5. A fixed frame 4 is fixedly connected to the bottom of the iron plate 1. A replacement component 11 is arranged inside the iron plate 1. A demolding component 22 is arranged at the bottom of the iron plate 1. The replacement component 11 includes threaded rods 111. The number of the threaded rods 111 is two. Belt pulleys 114 are fixedly connected to the backs of the two threaded rods 111. A belt 115 is in transmission connection with the outer surfaces of the two belt pulleys 114. A turning handle 112 is fixedly connected to the front of the threaded rod 111 on the left side. Square grooves 1 are opened at the top of the iron plate 1. The number of the square grooves 1 is two.

[0029] The two square grooves 1 are symmetrically arranged with the center of the iron plate 1 as the symmetry axis. The parts included in the two square grooves 1 are the same. Clamping blocks 113 are slidably connected to the inner walls of the square grooves 1. The number of the clamping blocks 113 is two.

[0030] Circular grooves 1 are opened inside the two clamping blocks 113. The inner walls of the two circular grooves 1 are both in threaded connection with the outer surfaces of the threaded rods 111. The sides of the two clamping blocks 113 close to each other are in contact. The bottoms of the two clamping blocks 113 are both in contact with the top of the fixed seat 2. By arranging the replacement component 11, specifically, the turning handle 112 is rotated counterclockwise to drive the threaded rod 111 to rotate, so that the two threaded rods 111 drive the two clamping blocks 113 to move away from each other during rotation without restricting the top of the fixed seat 2, so that the fixed seat 2 and the outer mold 5 can be removed and a new outer mold 5 can be replaced, enabling the same mold device to produce lamp shades of different sizes and improving the practicability of the device.

[0031] The demolding component 22 includes a motor 221. The bottom of the fixed frame 4 is fixedly connected to the top of the motor 221. A rotating rod 222 is fixedly connected to the top output end of the motor 221. A circular groove 2 is opened at the bottom of the iron plate 1. The inner wall of the circular groove 2 is rotatably connected to the top of the rotating rod 222.

[0032] A rotating block 223 is fixedly connected to the outer surface of the rotating rod 222. The top of the rotating block 223 is in contact with the bottom of the iron plate 1. The number of rotating shafts 225 fixedly connected to the bottom of the iron plate 1 is two.

[0033] Vibration blocks 224 are rotatably connected to the outer surfaces of both rotating shafts 225, and springs 226 are fixedly connected to the sides of the two vibration blocks 224 close to each other.

[0034] The sides of the two vibration blocks 224 close to each other are both in contact with the outer surface of the rotating block 223. Two square grooves II are formed inside the iron plate 1, and inserting plates 227 are in contact with the inner walls of the two square grooves II. The tops of the two inserting plates 227 are fixedly connected to the bottom of the fixed seat 2. By setting the demoulding assembly 22, specifically, the motor 221 is turned on to drive the rotating block 223 to rotate, so that the vibration blocks 224 contact and impact the surface of the inserting plates 227 to generate vibration. When the rotating block 223 continuously rotates, the two vibration blocks 224 repeatedly perform reciprocating motions, causing the outer mold 5 to vibrate and quickly demould the solidified lampshade on the surface of the outer mold 5, reducing the tediousness of the staff during demoulding and improving the production efficiency of the device.

[0035] A specific application of this embodiment is as follows: When the staff needs to produce lampshades of different sizes and types, the turning handle 112 is rotated counterclockwise to drive the threaded rod 111 to rotate in the inner wall of the circular groove I formed inside the iron plate 1. When the threaded rod 111 rotates, it will drive the pulley 114 to rotate. When the pulley 114 rotates, it will drive another pulley 114 to rotate through the belt 115 connected to it in transmission, enabling the staff to drive the two threaded rods 111 to rotate simultaneously when turning the turning handle 112. During the rotation of the two threaded rods 111, the two clamping blocks 113 threadedly connected to their surfaces will move away from each other. By moving the clamping blocks 113, the top of the fixed seat 2 is no longer restricted, so that the fixed seat 2 and the outer mold 5 can be removed and a new outer mold 5 can be replaced, enabling the same mold device to produce lampshades of different sizes and improving the practicality of the device. When the lampshade needs to be demoulded after solidification, the motor 221 is turned on to drive the rotating rod 222 to rotate. When the rotating rod 222 rotates, it will drive the rotating block 223 to rotate. During the rotation of the rotating block 223, it will push the vibration blocks 224 on the front and back to rotate and make them contact and impact the surface of the inserting plates 227. When the two vibration blocks 224 rotate, they will pull the springs 226, causing the springs 226 to deform. When the protruding sides of the rotating block 223 no longer contact the vibration blocks 224 during rotation, the deformed springs 226 will pull the two vibration blocks 224 back to their original positions through elastic force. When the rotating block 223 continuously rotates, the two vibration blocks 224 repeatedly perform reciprocating motions, causing the outer mold 5 to vibrate and quickly demould the solidified lampshade on the surface of the outer mold 5, reducing the tediousness of the staff during demoulding and improving the production efficiency of the device. When the outer mold is used to produce the lampshade, the outer mold is a stainless steel fine mesh, and the inner mold is an injection-molded perforated iron plate with a water filtering function.
