Description
Technical Field
The embodiment of the disclosure belongs to the technical field of mold ejection equipment, and particularly relates to a mold and a mold ejection device.
Background
In the production process of the traditional solid silica gel mold, the multi-plate mold structure is opened after molding by adopting an ejection system of a vulcanizing machine, and ejection and mold opening actions are carried out through ejection holes formed under the mold. Because the cavity number of the silica gel mold is very large, in order to prevent bad phenomena such as air trapping, air packing, glue shortage and the like during vulcanization molding, a vacuum cover of a vulcanizing machine is required to be used for vacuum vulcanization during vulcanization molding, but because of the process characteristics, vacuum vulcanization cannot be carried out by vacuumizing if a traditional top rod is adopted for ejection.
In view of the above, the inventor designs an ejection device which can effectively ensure the vacuum state during vulcanization molding without arranging an ejection hole below a mold, and perform the mold ejection and mold opening actions after the vulcanization operation is completed, thereby effectively improving the vulcanization molding cycle and the service life of the mold.

As shown in fig. 1, a mold ejection device 1, wherein the mold comprises a mold bottom plate, a mold middle plate 2 and a mold upper plate 3 which are matched with each other, and the mold ejection device 1 comprises an ejection seat 4, an ejection cross rod 5 and an ejection block 6. The first end of the ejection cross bar 5 is fixed to the ejection seat 4, and the ejection seat 4 is fixed to an ejection frame (not shown) of the vulcanizing machine. The ejection block 6 is disposed on the side walls of the upper mold plate 3 and the middle mold plate 2. Wherein, when the mould moves to the demoulding position, the second end of the ejection cross rod 5 is contacted with the ejection block 6 so as to separate the parting surface of the mould under the action of the ejection frame. The following is an example of the preparation of a solid silica gel mold.
Specifically, as shown in fig. 1, in the production process of a solid silica gel mold, the silica gel mold is vacuum vulcanized by using a vacuum cover of a vulcanizing machine, so that the silica gel mold is kept in a vacuum state during vulcanization molding, and the silica gel mold is ejected and opened by a mold ejecting device 1 after the vulcanization operation is completed. Specifically, after the vulcanizing operation is completed, the silicone mold is moved to the demolding position by the vulcanizing machine, and at this time, the second end of the ejector rail 5 contacts with the corresponding ejector block 6, and as shown in fig. 1, the second end of the ejector rail 5 abuts against the lower end of the corresponding ejector block 6. Under the action of the ejector frame, the ejector seat 4 moves along with the ejector frame and drives the ejector cross rod 5 to move upwards together, and the ejector block 6 is ejected to move the die middle plate 2 and the die upper plate 3, so that the parting surface of the die is separated.
According to the mold ejection device disclosed by the embodiment of the disclosure, the ejector seat, the ejector cross rod and the ejector block are arranged, so that the mold can be kept in a vacuum state during vulcanization molding, and the mold is ejected and opened under the condition that the vacuum vulcanization function is not damaged, so that the vulcanization molding period, the production efficiency and the service life of the mold are effectively improved, and the quality of a mold product is ensured.
Illustratively, as shown in fig. 1, the ejector blocks 6 are symmetrically disposed on both sides of the mold upper plate 3 and the mold middle plate 2.
Specifically, as shown in fig. 1, the ejector blocks 6 are symmetrically disposed on both sides of the mold upper plate 3 and both sides of the mold middle plate 2. As a specific example, as shown in fig. 1, the mold upper plate 3 and the mold middle plate 2 are symmetrically provided with a first ejection block 61 and a second ejection block 62, respectively, on both sides thereof. Wherein, two first ejection blocks 61 are respectively arranged at intervals on two sides of the upper die plate 3, and two second ejection blocks 62 are respectively arranged at intervals on two sides of the middle die plate 2. That is, two first ejection blocks 61 are symmetrically arranged at intervals on either side of the upper die plate 3, and two first ejection blocks 61 are also symmetrically arranged at intervals on the other side. Two second ejection blocks 62 are symmetrically arranged at intervals on any one side of two sides of the middle plate 2 of the die, and two second ejection blocks 62 are symmetrically arranged on the other side of the middle plate.
Further, the ejection seats 4 are respectively arranged at two sides of the die. Wherein, the first ejection cross rod 51 corresponding to the first ejection block 61 and the second ejection cross rod 52 corresponding to the second ejection block 62 are disposed on the ejection seat 4 at either side of the mold.
Specifically, as shown in fig. 1, two first ejector rails 51 and two second ejector rails 52 are provided on the ejector seat 4 located on either side of the mold. Wherein the first ejection cross rod 51 corresponds to the first ejection blocks 61 on both sides of the upper mold plate 3, and the second ejection cross rod 52 corresponds to the second ejection blocks 62 on both sides of the middle mold plate 2. The ejector rack drives the ejector seat 4 to move, and the ejector seat 4 drives the corresponding first ejector cross rod 51 and second ejector cross rod 52 to respectively contact the first ejector block 61 and the second ejector block 62, so that the upper die plate 3 and the middle die plate 2 are ejected to separate the parting surfaces of the dies.
Further, as shown in fig. 1, the height of the ejector rail 5 corresponding to the ejector block 6 of the mold upper plate 3 is greater than the height of the ejector rail 5 corresponding to the ejector block 6 of the mold middle plate 2.
Specifically, as shown in fig. 1, since the mold upper plate 3 is located at the upper end of the mold middle plate 2, the first ejector blocks 61 on both sides of the mold upper plate 3 are also located at the upper ends of the second ejector blocks 62 on both sides of the mold middle plate 2. The height of the first ejection cross rod 51 corresponding to the first ejection blocks 61 on two sides of the upper die plate 3 is set to be larger than the height of the second ejection cross rod 52 corresponding to the second ejection blocks 62 on two sides of the middle die plate 2, so that the first ejection cross rod 51, the first ejection blocks 61 and the second ejection cross rod 52 are simultaneously contacted with the second ejection blocks 52 in the moving process of the ejection seat 4, and the upper die plate 3 and the middle die plate 2 are simultaneously ejected and opened.
According to the mold ejection device, the ejector blocks and the ejector cross bars are symmetrically arranged, so that the mold can be kept in a vacuum state during vulcanization molding, and the mold is ejected and opened under the condition that the vacuum vulcanization function is not damaged, so that the upper mold plate and the middle mold plate can be synchronously ejected, the vulcanization molding cycle, the production efficiency and the mold service life are effectively improved, and the quality of a mold product is ensured.
