Problems solved by technology

For example: the sun visor in the car is one of the foam materials processed through different processes, and the sun visor in the car is the front windshield and rear windshield of the car. It is designed to avoid glare from the sun and can be moved back and forth. Therefore, the quality of the process in the production process of the sun visor directly affects the final quality of the product, but the current sun visor is used in the processing process Assembly line processing carries out the processing of each process, but in the processing process, each process needs to be equipped with an operator to operate, the production efficiency is low, the processing cost is high, and the human operation is definitely not as accurate as the mechanical operation, which will affect final quality

Embodiment 1

[0039] Such as figure 1 — Figure 8 As shown, an automatic molding device for a sun visor PU body provided in this embodiment includes a rotating mechanism 1, a controller 2, a release agent storage tank 3, a PU foaming automatic feeder 4 and a drying tunnel 5, The controller 2 controls the operation of the whole process, the release agent storage tank 3 is arranged on the front part of the PU foaming automatic feeder 4, and the described drying tunnel 5 is arranged on the PU foaming automatic feeder 4 The rear part of the rotating mechanism 1 includes a drive motor 1-1 and a circular track 1-2, and the output shaft of the drive motor 1-1 is connected with a drag chain 6 capable of circulating in the circular track 1-2 , a section of the annular track 1-2 is arranged in the drying tunnel 5, and more than one mold frame 7 moving circularly with the drag chain 6 is evenly distributed on the drag chain 6, and a mold 8 is arranged on each mold frame 7, The mold 8 includes a fixe...

Embodiment 2

[0056] Such as Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the general structure of the automatic forming device of a sun visor PU body provided in this embodiment is the same as that of Embodiment 1, the difference is that in order to realize automatic operation and reduce processing costs, on both sides of the circular track 1-2 The structure of the die frame 7 is completely symmetrical, and the fixed mold 8-1 is provided with two symmetrical locks 15, and the movable mold 8-2 is provided with a barb that cooperates with the locks 15 to make the mold 8 close. 16. On the annular track 1-2, relative to the rear of the first guide rod 14, there is a mold opening lever 17 that extends into the lock buckle 15 and molds the mold 8. The mold opening lever 17 is an inclined structure. The rear of bar 17 is provided with inclined second guide bar 18, and described second guide bar 18 comprises second inclined part 18-1 and second planar part 18-2, and described seco...

Embodiment 3

[0059] Such as Figure 13As shown, the general structure of the automatic forming device of a sun visor PU body provided in this embodiment is the same as that of Embodiment 1, the difference is that support rods 21 are provided on both sides of the mold frame 7 for ease of installation, so The crossbeam 13 is perpendicular to the support rods 21 on both sides respectively, and the chute 11 is respectively arranged on the inner wall of the support rods 21 on both sides, and penetrates with the end faces of the support rods 21, and any one of the support rods 21 is provided with There is a fixing plate 22 for fixing the rotating column 12 . During installation, one side of the rotating column 12 on both sides of the mold 8 is firstly inserted into the chute 11 on which the fixed plate 22 is installed, and then the rotating column 1 on the other side is inserted into the other chute 11 , so that under the action of the fixing plate 22, the mold 8 is positioned to prevent the mo...

Abstract

The invention discloses an automatic forming device and a production method of PU bodies of sun louvers. The automatic forming device comprises a rotating mechanism, a controller, a releasing agent storage tank, an automatic PU foaming feeding machine and a drying channel. An output shaft of a drive motor is connected to a drag chain, one section of an annular track is arranged in the drying channel, the drag chain is uniformly provided with a plurality of mold frames, each mold frame is provided with a mold, a releasing agent spraying gun on the releasing agent storage tank is located above the molds in the mold opening state, the molds are provided with guide wheels, the annular track is provided with a stop guide wheel in interference fit with the guide wheels after the mold closing process, a PU foaming nozzle of the automatic PU foaming feeding machine is located above the mold with a steel wire framework, inclined grooves are formed in the two sides of each mold frame, rotating columns matched with the inclined grooves are arranged on the two sides of each mold, each mold frame is provided with a cross beam, and a first guide rod is arranged at an outlet of the drying channel. According to the automatic forming device, the processing procedure is simpler, the labor force is saved, the production cost is lowered, the quality is improved, and automation is realized.

Description

technical field [0001] The invention relates to a production equipment and method for making products from foam materials, in particular to an automatic molding device for a PU body of a sun visor and a preparation method thereof. Background technique [0002] The most common foaming materials are soft foaming materials, which are mainly made of raw materials such as plastics (PE, EVA, etc.), rubber (SBR, CR, etc.), plus catalysts, foam stabilizers, foaming agents and other auxiliary materials. Physical foaming or cross-linking foaming causes a large number of fine foams to appear in plastics and rubbers, with increased volume and reduced density. Soft foamed materials are light in weight and soft, and have the functions of cushioning, sound absorption, shock absorption, heat preservation, and filtration. Widely used in electronics, home appliances, automobiles, sports and leisure industries. For example: the sun visor in the car is one of the foam materials processed throu...
