Description

Technical Field

[0001] This application relates to the technical field of injection molded parts production, and in particular to a drying device for injection molded parts production. Background Technology

[0002] Nylon (such as PA6 and PA66) is a crystalline thermoplastic material. Rapid cooling during injection molding can lead to uneven molecular chain orientation, creating internal stress. Boiling in water promotes molecular chain rearrangement and crystallization equilibrium through a high-temperature water environment, thereby reducing brittleness and preventing cracking.

[0003] like Figure 1 The nylon injection molded part 7 shown has pits on its surface. In the prior art, it is generally put directly into hot water to boil, and after boiling, it is taken out and placed in a transfer box. Because the injection molded part has pits on its surface and is cylindrical in shape, water will remain. During subsequent processing, the workers need to blow the water off each one. At the same time, the residual water can easily cause dust in the environment to adhere to the injection molded part, affecting the product quality.

[0004] Therefore, in order to improve production efficiency, it is necessary to air dry the product directly after boiling to avoid the problems of subsequent water blowing and dust adhesion. Utility Model Content

[0005] The purpose of this application is to provide a drying device for injection molded parts production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a drying device for injection molded parts production, employing the following technical solution:

[0007] A drying device for injection molded parts production includes a workpiece basket and a drying mechanism. The drying mechanism includes a drying trough, a support platform, a front water-cutting component, a rear water-cutting component, and baffles. The support platform is disposed inside the drying trough. The front water-cutting component and the rear water-cutting component are respectively disposed on both sides of the support platform. Baffles are symmetrically arranged on both sides inside the drying trough. The side of the workpiece basket can abut against the baffles. A drain pipe is connected to the side of the drying trough.

[0008] The workpiece basket includes a basket body and a top cover. The basket body is evenly provided with multiple slots for placing injection molded parts. The top cover is fixed to the basket body by studs, and the stud ends have hook connection parts.

[0009] Preferably, the baffle is fixed with slide blocks at both ends, and a slide groove is fixed on the side wall of the drying trough. The slide blocks are slidably connected in the slide groove. A cylinder is fixed on one side of the slide block and is fixed on the side wall of the drying trough. The cylinder is used to push the baffle to move back and forth.

[0010] By adopting the above technical solution, the workpiece basket can be flipped by the cylinder pushing the stop lever, which replaces the manual flipping of the workpiece basket and improves work efficiency.

[0011] Both the front-end water-cutting assembly and the rear-end water-cutting assembly include multiple water-cutting air knives arranged vertically side by side, and each water-cutting air knife is externally connected to a blower.

[0012] Preferably, to prevent water from accumulating on the surface of the support platform, the surface of the support platform is provided with several drainage grooves.

[0013] In summary, this application includes at least one of the following beneficial technical effects: the air drying device for injection molding production, by setting up a workpiece basket and an air drying mechanism, uses a baffle to push the workpiece basket back and forth from the top position, so that the water left on the surface of the injection molding part can be quickly flowed out, and then air dried by the front water cutting component and the rear water cutting component, which can ensure that the surface of the workpiece is dry, so as to facilitate subsequent processing and improve production efficiency. At the same time, it can also avoid dust adhesion and ensure product quality. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0020] This application discloses a drying device for injection molded parts production, referring to... Figure 2-4The device includes a workpiece basket 1 and a drying mechanism. The drying mechanism includes a drying trough 21, a support platform 22, a front water-cutting component 23, a rear water-cutting component 24, and a baffle 25. The support platform 22 is installed inside the drying trough 21. The front water-cutting component 23 and the rear water-cutting component 24 are respectively installed on both sides of the support platform 22. Baffles are symmetrically arranged on both sides inside the drying trough 21. The side of the workpiece basket 1 can abut against the baffle 25. A drain pipe 3 is connected to the side of the drying trough 21.

[0021] Both the front-end water-cutting component 23 and the rear-end water-cutting component 24 include multiple water-cutting air knives arranged vertically side by side, and the water-cutting air knives are connected to a blower.

[0022] Reference Figure 4 The workpiece basket 1 includes a basket body 11 and a top cover 12. The basket body 11 is evenly provided with multiple slots for placing injection molded parts. The top cover 12 is fixed to the basket body 11 by studs, and the stud ends have hook connection parts.

[0023] Reference Figure 3 The two ends of the stop lever 25 are fixed with slide blocks 4, and the side wall of the drying trough 21 is fixed with a slide groove 5. The slide blocks 4 are slidably connected in the slide groove 5. A cylinder 6 is fixed on one side of the slide block 4. The cylinder 6 is fixed on the side wall of the drying trough 21 and is used to push the stop lever 25 to move back and forth.

[0024] By using a cylinder 6 to push the stop lever 25 to move, the stop levers 25 on both sides can push the workpiece basket 1 to flip, replacing the manual flipping of the workpiece basket 1 and improving work efficiency.

[0025] Reference Figure 3 To prevent water from accumulating on the surface of the support platform 22, several drainage grooves 221 are provided on the surface of the support platform 22.

[0026] The implementation principle of the air drying device for injection molded parts production in this application embodiment is as follows:

[0027] In use, the staff places the injection molded parts into the workpiece basket 1 one by one, and then suspends the workpiece basket 1 in hot water for boiling. After boiling for a period of time, the workpiece basket 1 is lifted up and left at the top of the water tank for a while to allow excess water on the inner surface of the workpiece basket 1 to drip off quickly. Then it is suspended into the air drying tank 21 and placed on the support platform 22. Under the action of gravity, it can tilt against the baffle 25 on one side of the front water cutting component 23. At this time, it is left to stand still for a period of time to allow it to cool down naturally. After that, the water cutting air knife in the front water cutting component 23 air dries the workpiece basket 1 and the injection molded parts. After one side is dried, the cylinder 6 pushes the baffle 25 to adjust the rotation angle of the workpiece basket 1, so that the water remaining on the other side of the surface can flow out and be air dried by the rear water cutting component 24. This ensures that the surface of the workpiece is dry for subsequent processing, and at the same time, it can also prevent dust from adhering and ensure product quality.

[0028] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
