DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The utility model provides a technical solution: Figure 2 and Figure 3As shown, in this embodiment, an injection molding device for a router housing with automatic demolding includes a female mold 1 and a male mold 2, both of which are provided with a mold temperature regulating system, and are characterized in that: a demolding assembly 4 is installed in the female mold 1 and the male mold 2, and the demolding assembly 4 includes a plurality of ejector rods 401 slidably plugged in the female mold 1, and the plurality of ejector rods 401 are all in the molding position, and one end of the plurality of ejector rods 401 is fixedly connected to the same connecting frame 402, and a connecting column 403 is slidably plugged at both sides of the female mold 1, and one end of the two connecting columns 403 is fixedly connected to the outer wall of the connecting frame 402, and two springs 404 are fixedly connected between the connecting frame 402 and the female mold 1, and the two springs 404 are respectively sleeved on the outside of the two connecting columns 403.

[0026] A plurality of receiving grooves 405 are formed on the outer wall of one end of the concave mold 1 , and the other ends of the two connecting columns 403 and the plurality of ejector rods 401 can fit into the plurality of receiving grooves 405 , respectively.

[0027] The outer wall edges of the two connecting columns 403 and the multiple push rods 401 close to the die 1 are all provided with bevels 406, so that when the connecting columns 403 and the push rods 401 enter the receiving groove 405, they will not be unable to enter due to position offset.

[0028] The two connecting posts 403 are in contact with each other. When the punch 2 continues to move, the tension of the spring 404 is overcome and becomes longer until the die 1 and the punch 2 are completely overlapped, and the connecting post 403 also enters the corresponding receiving groove 405. The connecting post 403 can drive one end of multiple ejector pins 401 to enter the corresponding receiving groove 405 through the connecting frame 402, so that the internal shapes of the two molds form a whole. When the injection molding work is completed, the external driving device drives the punch 2 back to its original position. During this period, the pressure of the spring 404 decreases and gradually shortens. It drives the multiple ejector pins 401 to move out of the mold through the connecting frame 402. The finished product will be ejected no matter which mold it is in, and it will become convenient enough to take it out at this time.

[0029] like Figure 2 and Figure 4 As shown, the same reinforcement component 5 is installed between the die 1 and the punch 2. The reinforcement component 5 includes eight mounting blocks 501 fixedly connected at four corners of the die 1 and the punch 2. Each of the four mounting blocks 501 at one end is fixedly connected with an insertion rod 502, and each of the four mounting blocks 501 at the other end is fixedly connected with a limiting tube 503. The four insertion rods 502 are slidably inserted into the four limiting tubes 503 respectively.

[0030] A plurality of air outlet holes 504 are formed at one end of the circumferential outer wall of the four limiting tubes 503 , and the plurality of air outlet holes 504 are communicated with the inner space of the limiting tubes 503 .

[0031] When the punch 2 is moving, the punch 2 drives multiple insertion rods 502 to move synchronously through the mounting block 501. The insertion rods 502 are restricted by the limiting tube 503, which can ensure that the state of the punch 2 is sufficiently stable during the movement. When the insertion rods 502 are inserted into the limiting tube 503, excess air can be discharged to the outside through the air outlet 504, ensuring that the sliding process is not hindered.

[0032] like Figure 1 and Figure 2 As shown, a mounting frame 3 is fixedly connected to the outer wall of one end of the punch 2, and the mounting frame 3 surrounds the outside of the demoulding component 4. The mounting frame 3 can be used to connect the punch 2 and the external driving device.

[0033] like Figure 1 and Figure 2 As shown, an injection port 6 is provided on both sides of the top outer wall of the die 1 and the punch 2, and an exhaust port 7 is provided in the middle of the top outer wall of the die 1 and the punch 2. By setting four injection ports 6, it is possible to ensure that the injection is sufficiently complete and avoid defects in the finished product.

[0034] The utility model provides an injection molding device for a router housing capable of automatic demoulding, and the specific working principle is as follows:

[0035] When the device is working, the external driving device drives the punch 2 to approach the die 1, and then the two connecting pillars 403 contact each other. When the punch 2 continues to move, the tension of the spring 404 is overcome and becomes longer, until the die 1 and the punch 2 are completely overlapped, and the connecting pillar 403 also enters the corresponding receiving groove 405. The connecting pillar 403 can drive one end of the multiple ejector rods 401 to enter the corresponding receiving groove 405 through the connecting frame 402, so that the internal shapes of the two molds form a whole. When the injection molding work is completed, the external driving device drives the punch 2 back to its original position, and the spring 404 is pressed against the punch 2 to release the ejector rod 401. The pressure of 404 decreases and gradually shortens, and it drives multiple ejector rods 401 to move out of the mold through the connecting frame 402. The finished product will be ejected no matter which mold it is in, and it will be convenient to take it out. When the punch 2 is moving, the punch 2 drives multiple insertion rods 502 to move synchronously through the mounting block 501. The insertion rods 502 are restricted by the limiting tube 503 to ensure that the state of the punch 2 is more stable during the movement. When the insertion rods 502 are inserted into the limiting tube 503, the excess air can be discharged to the outside from the air outlet 504 to ensure that the sliding process is not hindered.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
