Description

Linear circulation rubber injection process

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

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.

Accordingly, it is an object of the present invention to provide a linear circulation type rubber injection process with high production efficiency.

Therefore, the linear circulation type rubber injection process of the present invention is suitable for injection molding a rubber material belt by a rubber injection machine, and the rubber injection machine can define an injection area along the line transportation direction and a number located downstream of the injection area. a vulcanization zone arranged in a straight line transport direction, the rubber injection machine and defining a manual reclaiming zone located in front of the injection zone, and a rear suction zone in the rear of the injection zone, the linear circulating rubber The injection process includes:

(A) preparing a plurality of mold sets, the number of the mold sets being equal to the total number of the injection zones plus the sulfur addition zones, such that the mold sets are respectively located in the injection zone, the post-shot pause zone, and one of Of the sulfur addition zones, one of the sulfur addition zones is temporarily vacant.

(B) when the mold set located in the shooting zone is performing the shot, synchronously transporting the mold set located in the other sulfur addition zone from the other sulfur addition zone to the manual take-up zone in the linear transport direction, And synchronously transporting the mold set located in the pause zone of the shot material from the post-projection pause zone to the vacant one of the sulphur zone in the linear transport direction.

The effect of the present invention is that the present invention can utilize the mold set located in the shooting zone to simultaneously transport the mold set located in another sulfur addition zone to the artificial reclaiming zone during the time of projecting, and will be located in the shot. The mold set in the pause zone after the material is transported to the vacant one of the sulphur zone to effectively utilize the shot time for the cyclic transport of the mold set.

In the present embodiment, as shown in FIGS. 13 and 14, the stock module 21 of the vacuum feeding unit 20 and the gate module 22 are matched with each other, and the rubber strip 200 is stored in the vacuum state. In the material tube 12, that is, in a state where the vacuum space 28 and the inside of the injection material tube 12 are both in a vacuum, the rubber material tape 200 is taken up by the injection screw 14 into the injection material tube 12 for storage. A rubber material (not shown) is formed in the injection tube 12.

Step 430: As shown in FIGS. 29 and 30, the rubber material formed by the rubber strip 200 after the stock is discharged is injected into the mold set 41 located in the shot-out area 310 in a vacuum state. In the present embodiment, as shown in FIG. 6, the vacuum cover 17 of the injection unit 10 is placed over the mold set 41 on the lower tray 15 of the injection unit 10 of the exit area 310 (see FIG. 30). The vacuum chamber 174 defined by the straight hood 17 of the injection unit 10 and the lower tray 15 can be used to store the rubber material (not shown) without air after the storage. The chamber 174 is evacuated to the mold set 41 located in the exit area 310 (see FIG. 30) and covered by the vacuum cover 17.

Step 440: As shown in FIGS. 29, 30, and 31, when the mold set 41 located in the shot-out area 310 is used to shoot the material by using the shot-out unit 10, the mold set 41 located in the sulfur-adding zone 320II is synchronously along the line.

In this embodiment, as shown in FIG. 19, the front mold-moving mechanism 55 of the front conveying device 52 can first transport the mold set 41 located on the vulcanization module 31 to the lower base 53, and then, for example, As shown in Figures 30 and 31, the front transfer device 52 can be moved from the first replacement position to the second replacement position. Thus, the mold set 41 located in the sulfur addition zone 320II can be used by the front transfer device 52. Transfer to the manual reclaiming area 330. Meanwhile, as shown in FIGS. 30 and 31, the rear conveying device 62 may first move from the third replacement position to the fourth replacement position, and then, as shown in FIG. 28, the rear mold-moving mechanism 67 of the rear conveying device 62. The mold set 41 located on the preheating lower platen 65 can be transported to the vulcanization module 31 located in the vulcanization zone 320I (see FIG. 31), and thus, as shown in FIGS. 30 and 31, the post-transportation is performed. The apparatus 62 can transport the mold set 41 located in the post-shot pause zone 340 to the vulcanization zone 320I, and, in the process, as shown in Fig. 26, the preheating of the rear transfer device 62 can be utilized. The upper platen 64 and the preheating lower platen 65 preheat the mold set 41 to the preheating temperature. Preferably, the preheating temperature is greater than each of the mold sets 41 in the respective sulfur addition zones 320I-320X (see Figure 31) shows the vulcanization temperature of the vulcanization operation on the vulcanization module 31 (see Figure 31). Thus, each mold set 41 can be effectively reduced in each vulcanization module 31 (see Figure 31). The time required to perform the vulcanization operation. It can be understood that, as shown in FIGS. 31 and 32, after the mold set 41 is transported by the rear conveyance device 62 to the vulcanization zone 320I, the rear conveyance device 62 moves from the fourth replacement position to the third replacement. The position is moved back to the pause zone 340 after the shot.

Step 450, as shown in 29, 32, 33, after the mold set 41 to be located in the shot-out area 310 completes the shot by the shot-out unit 10, the mold set 41 located in the shot-out area 310 is along the shot-out area 310. The lateral direction Y is transported to the shot stop zone 340.

Thus, as shown in FIGS. 32 and 33, the mold set 41 located in the shot discharge area 310 can be transported to the shot rear pause area 340 by the rear mold release mechanism 67 of the rear conveyance device 62.

Step 460, as shown at 29, 33, 34, transports the mold set 41 located in the manual take-up area 330 from the manual take-up area 330 to the exit area 310 in the transverse direction X. In the present embodiment, before the mold set 41 is moved to the shot-out area 310, as shown in FIG. 24, the mold mechanism 57 can cooperate with the vertical mold opening mechanism 56 to open the upper mold 412 of the mold set 41. In order to facilitate the user to take out the product in the lower mold 411 by manual retrieving, after the mold set 41 is again clamped, as shown in FIG. 21, the front mold-moving mechanism 55 of the front conveying device 52 can be The mold set 41 located on the lower base 53 is conveyed to the lower pallet 15 of the injection unit 10, and as shown in FIGS. 33 and 34, the front mold-moving mechanism 55 of the front conveyance device 52 can be used. The mold set 41 located in the manual take-up area 330 is transported to the shot area 310.

Therefore, when the injection unit 10 is used to project one of the mold sets 41, the front and rear conveying devices 52, 62 can be used to sequentially and the remaining mold sets 41 sequentially along the linear transport direction X. The injection unit 10 and the vulcanization module 31 are cyclically transported.

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 mold set 41 from the post-projection suspension zone 340 to the position. In the process of a sulfur addition zone 320I-320X, as shown in FIG. 26, the present invention can control the preheating platen driver 66 to drive the preheating upper platen 64 to continuously lift and lower several times to push the upper die 412 of the die set 41. Exhaust is performed 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 present invention can be further summarized as follows:

1. In the actual manufacturing of the rubber injection machine 100, the invention only needs to use eleven mold sets 41 for production. If the production capacity of the product is N per day, the single-die production efficiency of the invention reaches N/11. For example, for example, a large amount of products (the rubber soles of No. 8, 9, and 10) has a daily capacity of 240 pairs, and the single-mode production efficiency of the present invention can reach 21.8 dou/mo (240/11). According to the prior art, the single-die production efficiency produced by the rubber injection machine 100 of the present invention is superior to the prior art, so that the invention can effectively reduce the total use of the production line when the product is produced in a large amount. The number of molds reduces the cost of mold input.

2. The vulcanization module 31 of the rubber injection machine 100 used in the present invention adopts a fixed position design, and can be linearly driven by the platen driver 314 to move the lower hot plate 313 toward the upper hot plate 312. The mold group 41 is pressed. Compared with the prior art, the sulfurizing module 31 has better pressure resistance in the prior world, and can generate sufficient clamping tonnage. Therefore, the present invention can be used even if the injection unit 10 is damaged or stopped. The cold rubber material can also be manually placed into the mold set 41 to perform the production operation.

3. In the process of transporting the mold set 41 from the injection unit 10 to each of the vulcanization modules 31 by the post-transport device 62, the preheating upper and lower platens 64 of the rear transfer device 62 can be utilized. The mold set 41 is preheated, so that the present invention can effectively shorten the time required for the mold set 41 to perform the vulcanization operation on each of the vulcanization modules 31.

4. The present invention can utilize the stock module 21 of the vacuum feeding unit 20 and the gate module 22 to cooperate with each other, so that the rubber strip 200 is taken into the injection tube 12 by the injection screw 14 in a vacuum state for storage. The material can achieve the effect of vacuum feeding. Compared with the prior art, the 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 material or fluorescent material. In this case, the yield and appearance quality of the product can still be ensured.

5. The present invention can cover the mold set 41 by using the vacuum cover 17 of the injection unit 10, so that the mold set 41 is located in the vacuum chamber 174 defined by the vacuum cover 17 and the lower support 15 to allow storage. The rubber material after the material can be injected into the mold set 41 located in the vacuum chamber 174 under vacuum to achieve the effect of vacuum injection. Compared with the prior art, the present invention does not cause the rubber material to block the vacuum line and cause the mold. The problem of internal vacuum failure ensures that air entrainment does not occur between the cavity of the mold set 41 and the rubber material, so that the rubber material can be completely matched with the shape of the cavity to form a clear appearance texture and contour.

6. The present invention can utilize the time that the injection unit 10 shoots one of the mold sets 41, and the remaining mold sets 41 are sequentially placed in the linear transport direction X by the front and rear transporting devices 52, 62. The vulcanization zone 320I-320X, the manual reclaiming zone 330 and the post-projection suspension zone 340 are cyclically transported to effectively utilize the injection time of the injection unit 10 for the cyclic conveyance of the remaining die sets 41.

In summary, the linear circulation type rubber injection process of the present invention not only has high production efficiency, but also can effectively improve the quality and yield of the product, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
