Detailed Description

The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.

The die-casting die with the automatic de-pouring channel as shown in the figures 1-3 has the same structure as the traditional three-die-casting die and comprises a fixed die 1, a middle plate 2 and a movable die 3 which are arranged oppositely in sequence. Wherein the middle plate 2 and the movable die 3 are provided with product cavities, and products can be taken out only from between the middle plate 2 and the movable die. A pouring channel is arranged between the fixed die 1 and the middle plate 2. In the invention, a fixed die insert 4 is arranged on a fixed die 1, and a plurality of runner grooves 5 for forming three cross runners are arranged on the fixed die insert 4. The three runner grooves 5 are long straight grooves and are arranged in parallel along the vertical direction. This runner groove 5 has the negative draft inclination, and the cross gate can't directly drop from the notch in runner groove 5 after the die-casting is accomplished promptly, and runner groove 5 extends to the ingate. The middle plate 2 is provided with a middle plate insert 6, the middle plate insert 6 is provided with a pouring cavity for forming a sprue and a material cake, the pouring cavity has a positive draft angle, and the material cake and the sprue can be left on the fixed die 1 during die opening. And a pouring channel ejector rod 7 is arranged right ahead of one side of the pouring channel 5 along the inner sprue, the pouring channel ejector rod 7 horizontally moves along the direction of the pouring channel 5 to eject the cross gate from the fixed die insert 4, and the pouring channel 5 is designed with a die drawing inclination along the ejection direction.

In order to ensure the continuous die opening process, four corners of the outer sides of the fixed die 1, the middle plate 2 and the movable die 3 are provided with die locking mechanisms. The mold locking mechanism comprises a mold locking hook 8 the middle part of which is hinged on the middle plate 2. The front portion that the mode locking colluded 8 has the couple, has the lock module 9 with couple cooperation locking on the movable mould 3 simultaneously, is provided with kicking block 10 on the cover half 1, and kicking block 10 front end portion can be tightly in the couple top of mode locking colluding 8 on lock module 9 during the compound die, can be so that medium plate 2 and movable mould 3 realize the mode locking from this. The tail part of the mode locking hook 8 is provided with a pin hole which is limited by a pin shaft of the fixed die 1, and the mode locking of the middle plate 2 and the fixed die 1 can be realized by inserting the pin shaft into the pin hole. In addition, the middle part of the top block 10 is provided with a contact 11 which is in an arc-shaped bulge, and when the mold is opened, the pin shaft is firstly taken out, so that the mold locking hook 8 is separated from the fixed mold 1 to realize the mold opening process of the middle plate 2 and the fixed mold 1. When the top block 10 retreats to a certain distance, the contact 11 touches the tilted tail part of the mold locking hook 8, so that the hook is separated from the lock module 9, the mold opening of the middle plate 2 and the movable mold 3 is realized, and manual intervention is not needed in the process.

As shown in fig. 2, in this embodiment, the three runner ejector rods 7 are further connected with sliders 13, the sliders 13 are slidably fitted on guide rails 14 on the fixed mold 1, and the fixed mold 1 is further provided with a runner ejection cylinder 15 for driving the sliders 13.

Further, a blanking sensor 16 is arranged on the fixed die 1 and right below the ejection direction of the cross pouring channel, and is used for sensing whether the pouring channel is ejected out automatically and falls off successfully.

The mold opening steps of the invention are as follows:

1. and (3) taking down the mold locking nail between the mold locking hook 8 and the fixed mold 1, retreating the movable mold for mold opening, retreating the movable mold together with the middle plate under the action of the mold locking mechanism, and directly breaking and separating the cross gate and the product due to the negative draft angle of the gate groove 5, wherein the cross gate is left on the fixed mold 1.

2. The movable mould moves backwards continuously, the mould locking hook 8 is separated from the locking module 9 under the action of the contact 11, and therefore the middle plate 2 and the movable mould are separated to achieve product taking.

3. When the step 2 is carried out, the punch head at the fixed die side moves forward to eject the material cake from the discharging barrel, and the pouring gate ejector rod 7 ejects the cross pouring gate from the pouring gate groove 5, so that the automatic blanking of the pouring gate is realized; the runner ejector rod is of a hollow structure, so that ventilation, water supply and runner spraying of a release agent can be realized.

4. And a blanking inductor 16 below the pouring gate induces whether blanking is successful or not and feeds back, and if blanking is not induced, an alarm is given.

The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the embodiments are only used to help understanding the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the present description should not be construed as a limitation to the present invention.
