Problems solved by technology

[0003] At present, in the production process of glass fiber reinforced plastics, the three raw materials required for it are melted separately, and then melted and then added to the mold simultaneously for molding, which leads to the uneven mixing of the three raw materials after melting, resulting in The quality of the produced glass fiber reinforced plastics is degraded, which affects its use, and when melting the three raw materials, sometimes the three raw materials are placed for a long time, resulting in more moisture in the raw materials, but when melting It is carried out under sealed regulation, so that the water vapor generated during melting cannot be effectively removed, which will easily lead to pores on the surface of the produced glass fiber reinforced plastic, which will further affect its quality

Embodiment 1

[0029] refer to Figure 1-Figure 4 , a rapid prototyping device in the production process of glass fiber reinforced plastics, comprising a base 1, the upper end of the base 1 is fixedly connected with three melting cylinders 3 through a fixed rod 2, and the lower ends of the three melting cylinders 3 are jointly fixedly connected with a conveying block 4, and the conveying block 4 There is a mixing mechanism for mixing the raw materials. The mixing mechanism includes a chamber 5 set in the conveying block 4. The inner wall of the chamber 5 is rotatably connected with two rotating shafts 6, and the side wall of the rotating shaft 6 is fixedly connected with a plurality of stirring rods 7. A plurality of scraping teeth 8 are evenly distributed and fixedly connected to the side wall of the stirring rod 7 .

[0030] Further, when the two rotating shafts 6 rotate to drive a plurality of stirring rods 7 to rotate, the stirring rod 7 can stir and mix the three kinds of raw materials ...

Embodiment 2

[0041] refer to Figure 5-Figure 6 The difference from Example 1 is that the three melting cylinders 3 are all provided with a dehumidification mechanism for drying and dehumidifying the raw materials. The dehumidification mechanism includes a dehumidification cylinder 28 fixedly connected to the upper end of the melting cylinder 3, and the inner wall of the dehumidification cylinder 28 is sealed and slidably connected. The magnetic plate 29, the side wall of the magnetic plate 29 is elastically connected to the inner wall of the dehumidification cylinder 28 through the spring 30, and the inner wall of the dehumidification cylinder 28 is provided with a through hole close to the spring 30 to balance the pressure in the dehumidification cylinder 28 when the magnetic plate 29 slides back and forth. The inner wall of the conveying leaf 14 is embedded with a magnet 31 that is attracted to the magnetic plate 29, and the inner wall of the dehumidification cylinder 28 is fixedly conne...

Embodiment 3

[0045] refer to Figure 7-Figure 8 Different from Embodiment 2, a drying mechanism for drying silica gel particles is provided in the dehumidification cylinder 28. The drying mechanism includes a vertical plate 35 fixedly connected to the inner wall of the dehumidification cylinder 28, and the vertical plate 35 is fixed close to the side wall of the dehumidification bag 32. The first conductive plate 36 is connected, the side wall of the dehumidification bag 32 is fixedly connected with the second conductive plate 37 matching the first conductive plate 36, the dehumidification bag 32 is provided with a heating wire 38, the first conductive plate 36, the second conductive plate 37. The heating wire 38 is connected in series with the external power supply.

[0046] Furthermore, since the volume of the silica gel particles expands after absorbing moisture, and the volume expansion of the silica gel particles drives the expansion of the dehumidification bag 32 so that the first co...

Abstract

The invention discloses rapid molding equipment in a glass fiber reinforced plastic production process. The rapid forming equipment comprises a base, the upper end of the base is fixedly connected with three melting cylinders through fixing rods, the lower ends of the three melting cylinders are jointly and fixedly connected with a conveying block, the conveying block is provided with a mixing mechanism for mixing raw materials, and the mixing mechanism comprises a cavity formed in the conveying block. By arranging the mixing mechanism, a plurality of scraping teeth are driven to be in contact with raw materials when stirring rods rotate along the axis of rotating shafts, so that the three raw materials are stirred, separated and mixed uniformly, and the production quality of glass fiber reinforced plastics is improved; through arrangement of a conveying mechanism and a driving mechanism, the three melting cylinders can synchronously melt and convey the raw materials, and a third cross rod rotates to drive the two rotating shafts to rotate, so that the three raw materials are uniformly mixed, other driving equipment is not needed, and the whole device needs less power equipment and is low in energy consumption when in use.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic production, in particular to a rapid prototyping device in the production process of glass fiber reinforced plastic. Background technique [0002] Glass fiber reinforced plastic is a composite plastic based on glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin. [0003] At present, in the production process of glass fiber reinforced plastics, the three raw materials required for it are melted separately, and then melted and then added to the mold simultaneously for molding, which leads to the uneven mixing of the three raw materials after melting, resulting in The quality of the produced glass fiber reinforced plastics is degraded, which affects its use, and when melting the three raw materials, sometimes the three raw materials are placed for a long time, resulting in more moisture in the raw materials, but when melting It is carried out under sea...
