Description

Linear circulation full vacuum rubber injection machine

The present invention relates to an injection machine, and more particularly to a linear circulation type full vacuum rubber injection machine.

As shown in FIG. 1 , a disc type rubber injection molding machine includes a disc that can be intermittently rotated, twelve molds 2 disposed at equal angular intervals on the disc 1 , and an injection machine 3 . When the molds 2 are rotated to correspond to the injection machine 3, the injection machine 3 can inject rubber material into the molds 2. At this time, all the molds 2 are stopped, and the disc 1 carries the During the intermittent rotation of the mold 2, the molds 2 can perform the vulcanization operation on the heating and pressurization of the inner rubber material. In actual manufacture, one of the molds 2 corresponding to the injection machine 3 is performing the shot. At the same time, another mold 2 located at the last station position of the injection machine 3 is performing a manual mold opening and retracting operation to take out the product.

This type of molding machine needs to use twelve molds 2 at a time for production. If the production capacity of the product is N per day, the single-die production efficiency is only N/12. For example, for example, a large quantity of products (8, 9, The rubber sole of the 10th) has a daily capacity of 240 pairs, and its single-die production efficiency is only 20 pairs/mode (240/12).

Further, such a molding machine cannot preheat the rubber material before the vulcanization operation of the internal rubber material by the molds 2. In addition, since the pressurizing oil passage for pressurizing the molds 2 of the molding machine is to be disposed via the swing mechanism (not shown) of the disc 1, the innate pressure resistance is poor, resulting in The mold clamping tonnage is also not large enough, so that once the injection machine 3 is damaged or stopped, the user cannot manually put the cold rubber material directly into the molds 2 to perform the production operation.

In addition, in order to improve the quality of the product, the conventional rubber injection molding machine directly vacuums the cavity inside the mold during the injection process of the rubber material. However, such a practice often causes the rubber material to block the vacuum line, resulting in a problem. In-mold vacuum failure, and such a method can not effectively exclude the air contained in the rubber material itself. In the case where the rubber material is a transparent material or a fluorescent material, the appearance of the product often still has a bad condition with small bubbles. The quality of the product cannot be guaranteed.

Therefore, the object of the present invention is to provide a linear circulation type full vacuum rubber injection machine which is efficient in production and can effectively improve the quality of the product.

The way the product in the lower mold 411 is taken out.

It is worth mentioning that if the user finds that the product still contains a bubble-containing defect after the product is taken out, the rear conveyance device 62 transports the loaded mold group 41 from the injection unit 10 to either one. During the process of the vulcanization module 31 (ie, moving from the third replacement position to the fourth replacement position), as shown in FIG. 26, the preheating platen driver 66 can be controlled to drive the preheating upper platen 64 to continuously elevate several times. To push the mold set The upper mold 412 of 41 is exhausted to extrude the air contained in the rubber material in the mold set 41 so as not to affect the molding quality of the product.

Through the above description, the advantages of the new model can be summarized as follows:

1. In actual manufacturing, the new model only needs to use eleven mold sets 41 for production. If the product has a daily capacity of N, the new single-mode production efficiency can reach N/11, for example, for example, The large-volume products (rubber soles of No. 8, 9, and 10) have a daily production capacity of 240 pairs, and the new single-mode production efficiency can reach 21.8 mod/modul (240/11), compared with conventional technology. The single-die production efficiency of each mold set 41 of the present invention is superior to the conventional technology, so that when a large amount of products are produced, the novel can effectively reduce the total number of molds required for the production line and reduce the input cost of the mold.

2. The vulcanization module 31 of the present invention adopts a fixed position design, and the platen driver 314 can be used to linearly drive the lower hot plate 313 to move toward the upper hot plate 312 to pressurize the die set 41.

Therefore, the present invention can be manually cold even if the injection unit 10 is damaged or stopped. The rubber material is placed directly into the mold sets 41 for production operations.

3. In the process of transporting the die set 41 of the strip from the injection unit 10 to any of the vulcanization modules 31, the preheating upper and lower press plates 64 and 65 can be used for the stripping. The mold set 41 is preheated to effectively shorten the time required for the mold set 41 of the strip to perform the vulcanization operation on the vulcanization module 31.

4. The vacuum feeding unit 20 of the present invention can cooperate with the gate module 22 by using the material preparation module 21, and the rubber material belt 200 is wound into the injection material tube 12 by the injection screw 14 under vacuum to store the material. In order to achieve the effect of vacuum feeding, compared with the prior art, the present invention can effectively exclude the air contained in the rubber material itself, and avoid the bad condition that the product contains bubbles, and the rubber material is transparent or fluorescent material. In this case, the yield and appearance quality of the product can still be ensured.

5. The injection unit 10 of the present invention can cover the mold set 41 by using the vacuum cover 17 to inject the stored rubber material into the mold set 41 located in the vacuum cover 17 under vacuum to achieve vacuum ejection. Compared with the prior art, the present invention does not cause the problem of vacuum failure in the mold caused by the rubber material blocking the vacuum line, and ensures that air entrainment does not occur between the cavity and the rubber material of the mold set 41, so that the rubber The material can be perfectly matched to the shape of the cavity to create a clear appearance and contour.

6. The time for the front and rear transporting devices 52, 62 of the present invention to be ejected by the ejecting unit 10 is cyclically transported along the linear transport direction X between the ejecting unit 10 and the vulcanization modules 31. The remaining mold set 41 of the shot is taken.

In summary, the linear recirculating full-vacuum rubber injection machine of the present invention not only has high production efficiency, but also can be applied to the production by using manual de-cooling materials, and can effectively improve the quality and yield of the product, so it can be achieved. The purpose of this new type.
