AI Technical Summary
When traditional molding molds are used to shape ABS plastic panels, the plastic panels bend irregularly on both sides as they move within the molding channels, resulting in uneven surfaces and inconsistent thickness.
The system uses a combination of front and rear molds. The front mold has a concave arc-shaped front shaping channel, while the rear mold has a straight rear shaping channel. After the ABS plastic panel is initially cooled in the front shaping channel, it enters the rear shaping channel for secondary cooling and shaping.
This effectively eliminates the problem of uneven stress in plastic panels, ensuring that the shaped panels are flat and have a uniform thickness.

Abstract
Description
Technical Field
[0001] This utility model relates to molding molds for plastic panels, and more particularly to a molding module specifically designed for ABS plastic panels. Background Technology
[0002] When the plastic panel emerges from the extruder die, it has not yet cooled and solidified. Therefore, it needs to be guided into a setting mold for cooling and solidification. Traditional setting molds use straight forming channels to shape flat plastic panels. However, for flat plastic panels made of ABS material, due to the material's properties, if straight forming channels are used, the plastic panel will irregularly bend downwards on both sides as it moves within the forming channels. This results in uneven stress distribution on the panel surface, leading to uneven thickness and a non-flat surface. Utility Model Content
[0003] The present invention aims to provide a molding module specifically for flat plastic panels made of ABS material, so as to eliminate the above-mentioned defects of traditional plastic panel molding molds.
[0004] Therefore, the present invention adopts the following technical solution:
[0005] The ABS plastic panel shaping module includes a front mold and a rear mold arranged at a distance from each other. The front mold has a front shaping channel that runs through the front and rear. The rear mold has a rear shaping channel that runs through the front and rear and connects to the front shaping channel. Both the front and rear shaping channels are horizontal flat holes, and their horizontal width, vertical height, and lowest point height are the same. The top and bottom surfaces of the front shaping channel are concave arc surfaces that curve upwards to the left and right, and the left and right sides are flat surfaces. The top and bottom surfaces, as well as the left and right sides of the rear shaping channel, are flat surfaces.
[0006] This invention features a front mold and a rear mold. The front mold has a recessed front shaping channel, and the rear mold has a straight rear shaping channel. The ABS plastic panel can be cooled and shaped by the front shaping channel to eliminate the effects of uneven stress and complete the initial cooling and shaping before entering the rear shaping channel for secondary cooling and shaping. This avoids unevenness and uneven thickness of the plastic panel after shaping. Attached Figure Description

[0013] To better understand this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] like Figure 1 and 4 The ABS plastic panel shaping module shown includes a base plate 30 and a front mold 10 and a rear mold 20 disposed at the top of the base plate 10 at a distance from each other. Both the front mold 10 and the rear mold 20 are rectangular blocks with equal length, width and height. The front mold 10 has a through front shaping channel 10.1, and the rear mold 20 has a through rear shaping channel 20.1 that connects to the front shaping channel 10.1. Both the front shaping channel 10.1 and the rear shaping channel 20.1 are horizontal flat holes with the same horizontal width, vertical height and lowest point height. The top and bottom surfaces of the front shaping channel 10.1 are concave arc surfaces that curve upwards to the left and right, and the left and right sides are flat surfaces. The top and bottom surfaces and the left and right sides of the rear shaping channel 20.1 are flat surfaces.
[0015] like Figure 2 and 5 As shown, the front mold 10 includes a front upper plate 11, a front lower plate 12, a front left support block 13, a front right support block 14, and a front top plate 15. The front upper plate 11 and the front lower plate 12 are vertically spaced apart, and the front left support block 13 and the front right support block 14 are horizontally spaced between the front upper plate 11 and the front lower plate 12. The front upper plate 11, the front lower plate 12, the front left support block 13, and the front right support block 14 are spaced apart to form a front shaping channel 10.1. The front top plate 15 is located on top of the front upper plate 11. The left sides of the front upper plate 11, the front lower plate 12, and the front top plate 15 are locked and fixed to the base plate 30 together with the front left support block 13 by a first bolt 16, and the right sides of the front upper plate 11, the front lower plate 12, and the front top plate 15 are locked and fixed to the base plate 30 together with the front right support block 14 by a second bolt 17. The front mold 10 has front air holes on both the left and right sides for connecting the front shaping channel 10.1 and the cooling device.
[0016] like Figure 3 and 6As shown, the rear mold 20 includes a rear upper plate 21, a rear lower plate 22, a rear left support block 23, a rear right support block 24, and a rear top plate 25. The rear upper plate 21 and the rear lower plate 22 are vertically spaced apart. The rear left support block 23 and the rear right support block 24 are horizontally spaced between the rear upper plate 21 and the rear lower plate 22. The rear upper plate 21, the rear lower plate 22, the rear left support block 23, and the rear right support block 24 are spaced apart to form a rear shaping channel 20.1. The rear top plate 25 is located on top of the rear upper plate 21. The left side of the rear upper plate 21, the rear lower plate 22, and the rear top plate 25 is locked and fixed to the rear left support block 23 on the base plate 30 by a third bolt 26. The right side of the rear upper plate 21, the rear lower plate 22, and the rear top plate 25 is locked and fixed to the rear right support block 24 on the base plate 30 by a fourth bolt 27. The left and right sides of the rear mold 20 are provided with rear air blowing holes for connecting the rear shaping channel 20.1 and the cooling device.
[0017] In use, the ABS plastic panel coming out of the extruder die is first guided into the front shaping channel 10.1 of the front mold 10, and then the ABS plastic panel coming out of the front mold 10 is guided into the rear shaping channel 20.1 of the rear mold 20. Since the bottom surface of the front shaping channel 10.1 is a concave arc surface, the left and right sides of the ABS plastic panel will not bend irregularly downward under the support of the front shaping channel 10.1, so that the stress of each part is uniform and does not deform. After the front mold 10 has been initially cooled and the ABS plastic panel has been initially shaped, it is not easy for each part to deform again. Therefore, the shaping can be completed by secondary cooling through the straight rear shaping channel 20.1.
