Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an automotive parts manufacturing apparatus. Background Technology

[0002] Vacuum forming is a plastic molding process that involves placing a heated and softened plastic sheet onto a specific mold. A vacuum is then created to force the sheet to adhere tightly to the mold surface, thus achieving the desired shape. After cooling and solidification, it becomes various automotive parts. Vacuum forming offers significant advantages in the automotive parts manufacturing industry. In terms of cost, the process is relatively simple, mold making costs are low, effectively reducing production investment. Furthermore, suitable plastic materials can be selected based on the needs of different parts, such as polyethylene with good toughness and polypropylene with high strength, ensuring part performance while controlling costs.

[0003] Vacuum forming is widely used in the production of automotive parts. For interior components, it's used to produce dashboard housings, center console trim panels, and door panels, resulting in smooth surfaces, aesthetically pleasing designs, and an enhanced overall feel. For exterior components, vacuum forming is also frequently employed for headlight covers and bumper liners to meet the diverse functional requirements of automotive parts.

[0004] To meet the requirements for the appearance, structure and installation of parts, the mold is equipped with undercuts. From the overall appearance of the mold, the undercuts are grooves recessed into the main body of the mold. The thermoplastic film is attached to the groove and gets stuck in the undercut after cooling and hardening, making it difficult to demold the product.

[0005] Therefore, it is necessary to provide an automotive parts manufacturing apparatus to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an automotive parts production device that can improve the demolding efficiency of parts.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An automotive parts production apparatus includes: a base plate, a mold provided at the upper end of the base plate, the mold having undercuts around its perimeter, and movable buckles horizontally hinged at the undercuts.

[0009] Preferably, the movable buckle extends horizontally outward to the outside of the undercut edge.

[0010] Preferably, the base plate is provided with a condenser pipe, and the two ends of the condenser pipe are provided with interfaces that can be connected to external water pipes.

[0011] Preferably, the condenser tubes are arranged horizontally in an S-shape.

[0012] Preferably, the interface at the end of the condenser tube is located at the lower end of the base plate and is perpendicular to the base plate.

[0013] Preferably, the interface is made of metal and is detachably connected to the condenser tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This utility model achieves the effect of assisting in the demolding of automotive parts by setting a movable buckle. Compared with the existing fixed movable buckle, it can improve the demolding efficiency of automotive parts.

[0016] (2) By setting a longer movable buckle, the present invention can further facilitate demolding. When the thermoplastic film is attached to the movable buckle and hardened, the thermoplastic film at the movable buckle is lifted by the movable buckle and its surface protrudes slightly. In this way, the top of the movable buckle extends into the other side of the thermoplastic film. When the automotive parts are demolded, the movable buckle presses against the inside of the automotive parts and rotates, reducing the friction between the automotive parts and the mold surface, thereby facilitating the demolding operation.

[0017] (3) The condenser tube of this utility model is arranged horizontally in an S-shape. The S-shaped arrangement increases the length of the condenser tube, which means that the coolant in the condenser tube has a longer flow time in the mold and the contact area between the coolant and the mold is larger, resulting in a better cooling effect of the coolant on the mold.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0024] First embodiment:

[0025] like Figures 1-2 As shown, the automotive parts production apparatus provided by this utility model includes: a base plate 10, and a mold 11 provided on the upper end of the base plate 10. In this embodiment, the automotive mold refers to a mold with a buckle 12 mechanism. A movable buckle 13 is horizontally hinged at the buckle 12, that is, the movable buckle 13 can be folded at the bottom of the buckle 12. During production, the thermoplastic film is attached to the mold 11, and a part of the thermoplastic film is attached to the upper end and side of the buckle 12. When the thermoplastic film cools and hardens, due to the effect of thermal expansion and contraction of the material, the thermoplastic film adheres more tightly to the mold 11 and the buckle 12. This is also a very important factor in the difficulty of demolding in the prior art. However, due to the addition of the movable buckle 13, when the product is demolded after hardening, the product is subjected to an upward pushing or pulling force from the outside. For example, when the worker or robot uses a suction cup to lift the product surface upward, the movable buckle 13 is subjected to the friction of the thermoplastic film on its side wall and folds upward, thereby getting rid of the adhesion at the buckle 12 after the part is formed.

[0026] By setting up the movable buckle 13, the effect of assisting in the demolding of automotive parts can be achieved. Compared with the existing fixed movable buckle 13, it can improve the demolding efficiency of automotive parts.

[0027] Second embodiment:

[0028] like Figure 1 The movable buckle 13 extends horizontally outward to the edge of the inverted buckle 12. That is to say, when the movable buckle 13 is in the initial horizontal state, its far edge extends out of the edge of the inverted buckle 12, and a part of the inverted buckle 12 is suspended.

[0029] By setting a longer movable buckle 13, demolding can be further facilitated. After the thermoplastic film is attached to the movable buckle 13 and hardened, the thermoplastic film at the movable buckle 13 is lifted by the movable buckle 13 and its surface protrudes slightly. In this way, the top of the movable buckle 13 extends into the other side of the thermoplastic film. When the car parts are demolded, the movable buckle 13 presses against the inside of the car parts and rotates, reducing the friction between the car parts and the surface of the mold 11, thereby facilitating the demolding operation.

[0030] Third embodiment:

[0031] like Figures 3-4As shown, in order to improve the curing speed of the thermoplastic film, a condenser pipe 20 is provided in the base plate 10. The condenser pipe 20 can be a reserved channel for processing the mold 11, for the flow of cold water, oil, etc. The two ends of the condenser pipe 20 are provided with interfaces 21, which can be connected to external water pipes. The coolant in the external water pipe enters from one end interface 21 and flows out from the other end interface 21. In this process, the heat in the mold 11 is conducted to the coolant, thereby achieving the effect of reducing the temperature of the mold 11. As the temperature of the mold 11 decreases, the thermoplastic film attached to it cures faster.

[0032] Fourth embodiment:

[0033] To further improve the cooling effect of the condenser tube 20 on the mold 11, the condenser tube 20 is arranged horizontally in an S-shape. The S-shaped arrangement increases the length of the condenser tube 20, which means that the coolant in the condenser tube 20 has a longer flow time in the mold 11, and the contact area between the coolant and the mold 11 is larger, resulting in a better cooling effect of the coolant on the mold 11.

[0034] Fifth embodiment:

[0035] like Figures 3-4 As shown, the interface 21 at the end of the condenser tube 20 is located at the lower end of the base plate 10 and is perpendicular to the base plate 10. The interface 21 is located at the lower end of the base plate 10 rather than on the side wall to reduce collision with other parts of the thermoforming device. The interface 21 is made of metal and has threads on the upper outer wall. The inner wall of the condenser tube 20 has threads that are compatible with the interface 21. Therefore, the interface 21 can be detachably installed on the condenser tube 20, which facilitates the maintenance of the interface 21 in the future.

[0036] Working principle: During production, the thermoplastic film is attached to the mold 11, with a portion of the thermoplastic film attached to the upper end and sides of the undercut 12. After the thermoplastic film cools and hardens, due to the effect of thermal expansion and contraction, the thermoplastic film adheres more tightly to the mold 11 and the undercut 12. This is a significant factor contributing to the difficulty in demolding in the prior art. However, due to the addition of the movable buckle 13, when the hardened product is demolded, it is subjected to an upward pushing or pulling force from the outside. For example, when a worker or robot uses a suction cup to lift the product upward, the movable buckle 13 is subjected to the frictional force of the thermoplastic film on its side wall, causing it to fold upward and thus break free from the adhesion of the part at the undercut 12 after molding.

[0037] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
