Description

Technical Field

[0001] The invention relates to a production device for a seat cushion of an electric bicycle, in particular to an automatic injection molding and blanking device for the seat cushion of an electric bicycle. Background Art

[0002] The seat cushion of an electric bicycle includes a seat cushion, an elastic layer arranged on the seat cushion, and leather arranged above the elastic layer. The seat cushion is an injection molded part, and the elastic layer is fixed to the seat cushion through the leather. The seat cushion is also provided with a rotating shaft and a locking hook. The rotating shaft is used to connect with the frame to open the seat cushion, so as to facilitate placing items in the storage slot in the frame. The locking hook is used to connect with the lock on the frame to lock the seat cushion. Some seat cushions are also provided with nuts and / or screws for connecting other parts.

[0003] In existing injection molding processes, inserts such as shafts, lock hooks, nuts and screws are manually inserted into the mold cavity, that is, the operator places the shaft into the corresponding cavity of the mold in the open mold state, and then closes the mold for injection molding. This method requires a short wait after the mold is opened before operation, because the temperature is high when the mold is just opened, which is easy to burn, resulting in low overall injection molding efficiency, high labor intensity for operators, and safety hazards.

[0004] In the existing injection molding process, after the injection molding is completed, the seat cushion is mainly demolded manually by workers, who remove the seat cushion from the mold and lay it flat, then cut off the sprue with diagonal pliers, and then place the seat cushion on the transfer device. This method results in a large workload for operators, and due to the high temperature of the mold and the product, burns are prone to occur. In order to avoid burns, the mold opening time needs to be extended to reduce the temperature of the mold and the product to a suitable temperature, which leads to a lower overall efficiency and the risk of pinching. Summary of the invention

[0005] In order to solve the above problems, the present invention provides an automatic injection molding and unloading device for a seat cushion of an electric bicycle, and the specific technical solution is as follows: An automatic injection molding and unloading device for a seat cushion of an electric bicycle comprises an injection molding machine and a mold arranged on the injection molding machine, and also comprises: an automatic insert feeding device, arranged on one side of the injection molding machine; a three-axis moving device, arranged on the injection molding machine; a demoulding device, arranged on the three-axis moving device; an insert feeding device, arranged on the three-axis moving device and / or the demoulding device; and a sprue cutting device, arranged on one side of the injection molding machine or the three-axis moving device; wherein the three-axis moving device is used to drive the insert feeding device to install the insert sent out by the automatic insert feeding device into the cavity of the mold and to drive the demoulding device to move the molded seat cushion to the outside of the injection molding machine and cut off the sprue through the sprue cutting device.

[0006] Compared with the prior art, the present invention has the following beneficial effects: The automatic injection molding and unloading device for an electric bicycle seat cushion provided by the present invention automatically checks the insert into the mold cavity through an insert automatic feeding device and an insert loading device in cooperation with a three-axis moving device, and realizes automatic unloading of the seat cushion and automatic cutting of the water outlet through a touch device and a water outlet shearing device in cooperation with the three-axis moving device, thereby shortening the mold opening time, eliminating the risk of scalding, effectively improving the efficiency of injection molding, reducing the labor intensity of operators, and improving safety.

The rotating shafts are first arranged in sequence by the first disc vibrating feeder 411 and then sent out through the first feeding trough 4112, and then the rotating shafts are moved in the first delivery trough 4131 to the end of the first delivery trough 4131 by the first vibrator 412, and are located in the second loading trough 4132.

[0016] In order to facilitate the processing of the first delivery groove 4131 , the automatic shaft feeding device 41 also includes a first material blocking plate 415 , which is fixed to the end of the first delivery groove 4131 by screws to block the shaft so that the shaft is located in the first delivery groove 4131 .

[0017] In order to avoid the first disc vibrating feeder 411 and the first vibrator 412 from working continuously and reduce energy consumption, the automatic shaft feeding device 41 also includes a first sensor 416.

The three-axis moving shaft drives the ejection substrate 43 and the rotating shaft loading cylinder 441 to move to the top of the first delivery guide rail 413 to continue grabbing the material, and prepares for the installation of the next rotating shaft. The rotating shaft can be installed after the cushion seat is taken out, thereby shortening the waiting time and improving the overall efficiency of injection molding.

[0019] The turning angle of the flip cylinder 42 is 90 degrees. When the flip cylinder 42 is in the initial position, the demoulding substrate 43 is in a vertical state. The demoulding substrate 43 is arranged opposite to the mold, and the rotating shaft can be inserted into the mold. After the flip cylinder 42 rotates 90 degrees, the demoulding substrate 43 is in a horizontal state. The rotating shaft loading seat 442 is above the first delivery slot 4131 and is arranged opposite to the second loading slot 4132, so as to grab the rotating shaft from the second loading slot 4132, avoid the interference between the grabbing and releasing device and the first delivery guide rail 413 when the demoulding substrate 43 is in a vertical state, and provide stability and reliability of loading. When loading the rotating shaft, the flip cylinder 42 can also be not started, and the rotating shaft can be grabbed from one side of the second loading slot 4132.

[0025] The rotating shaft feeding cylinder 441 and the locking hook feeding cylinder 451 are alternately placed on the demoulding base plate 43 without affecting each other's work, and are switched by the demoulding rotating cylinder 48 .

[0026] The structures of the automatic screw feeding device 56 and the automatic nut feeding device 57 are similar to those of the lock hook feeding device 45 and the rotating shaft feeding device 44, both of which include a disc vibrating feeder and a vibrator. They are existing mature products and will not be described in detail here.

[0027] like Fig.13 and Fig.14As shown, the screw feeding device 71 and the nut feeding device 72 have the same structure and are existing mature products, which will not be described in detail here.
