Description

System for molding of rubber products

The present invention relates to a rubber product molding system, and more particularly, to systemize the injection machine and the press machine integrally so as to use only the advantages of the injection machine and the press machine to minimize the product loss in the process of forming the product. In addition, runner loss does not occur from the beginning, and any type of product can be continuously and automatically formed in a short time.

Generally, rubber products are used as parts of various devices and apparatuses, and molding has been generally recognized as using only an injection machine independently or a press machine alone.

Injection molding machine used for molding conventional rubber products, injection mold joining process of forming the injection mold assembly by contact bonding the lower mold for injection with the upper mold for injection, as is commonly known in the art, and ribboned rubber A rubber product forming process for supplying the rubber raw material as measured in the injection mold assembly while forming a proper amount of raw material and molding the rubber product in the shape of the injection mold assembly, and the injection mold assembly at a predetermined temperature. The heating process of baking a molded rubber product by holding it for a predetermined time and molding it into a rubber product of a perfect shape, and separating the molded rubber product baked and molded in the shape of the injection mold assembly by the heating process from the injection mold assembly. The rubber product separation process is performed sequentially to mold the rubber product.

Therefore, when the lower mold for injection moves upward and is combined with the upper mold for injection to form an injection mold assembly, the injection mold assembly is weighed by an appropriate amount by an improved means in which a raw material of ribbon rubber is integrally integrated into the injection mold assembly. Since the rubber product is supplied in the shape of the injection mold assembly, only the shape is provided and not baked.

Then, the lower heater in the lower mold for injection and the upper heater in the upper mold for injection are heated to maintain the temperature of the injection mold assembly at 150 to 180 ° C., which is a temperature sufficient for the rubber product to be completely molded, for a predetermined time. The moldable rubber product in the injection mold assembly is baked and completed to be molded into a rubber product of a perfect shape. The molded rubber products are numbered according to the mold groove arrangement state of the upper mold and the lower mold of the injection mold assembly and the shape thereof. It can be understood that the shape is also determined as is determined.

In this manner, after the rubber product is molded, the injection lower mold and the injection mold forming the injection mold assembly are separated, and then the user artificially takes out the molded rubber product.

On the other hand, the rubber product immediately after molding is integrated with the runner loss, which is a molded product in the passage for injecting the rubber raw material into the injection mold assembly, and the product loss, which is a molded part of the fine gap between the injection upper mold and the injection lower mold, as shown in FIG. Since the post-work to remove the runner loss and the product loss attached to the rubber product after it must be sealed.

However, such a conventional injection molding machine does not need to separately match the weight of the rubber raw material to be molded into the rubber product, and it is possible to mold even a rubber product with a structurally complicated shape or a large size, and has the advantage of low loss rate of the rubber raw material. It does not mold a lot of quantity at once, and also has the disadvantage that the price of the device is expensive.

In addition, in the process of supplying the rubber raw material into the injection mold for molding a rubber product, since the rubber raw material always remains in the pipeline for supplying the rubber raw material into the injection mold assembly, the rubber raw material supplied into the moving mold is baked and molded. When raw rubber remaining in the supply line is baked as it is formed, the runner loss can only be molded in the shape of the supply line. Therefore, after removing the molded rubber product, the product is removed separately from the product loss. As the runner loss must be performed, a large number of workers are required, as well as a long time to produce a rubber product in perfect condition, as well as a large drop in production.

The press machine used for molding a conventional rubber product, as is commonly known in the art, weighs the plate-shaped rubber raw material with a proper weight and puts the weighed rubber raw material on the lower mold for injection, and the titration. Rubber product pseudo-molding process of forming a rubber mold assembly while pressing the mold lower body for injection of the raw material into the weight, and forming a mold mold body in contact with the injection mold. The heating process for baking a molded rubber product by holding it at a temperature for a predetermined time to form a rubber product of a perfect shape, and the rubber product molded and baked in the shape of the press mold assembly by the heating process. The rubber product separating process is performed sequentially to form the rubber product have.

Therefore, the rubber raw material of the plate-shaped piece is first weighed as much as the quantity to be put into the rubber product to be molded and adjusted to an appropriate weight, and then the weighed plate-shaped rubber raw material piece is placed on the press die.

In this state, when the lower die for press moves upward and is brought into contact with the upper die for press, a mold assembly is formed, and a rubber product is molded in the shape of the press mold assembly.

Then, the lower heater in the lower die for press and the upper heater in the upper die for press are heated to maintain the temperature of the press mold assembly at 150 to 180 ° C., which is a temperature sufficient for the rubber product to be completely molded, for a predetermined time. As the molded rubber product in the press mold assembly is baked, the rubber product is molded into a complete shape. The molded rubber products are numbered according to the mold groove arrangement state of the upper mold and the lower mold of the injection mold assembly. It can be understood that the shape is also determined as is determined.

In this way, after the rubber product is molded, the press lower mold and the press upper mold forming the press mold assembly are separated, and the user artificially takes out the molded rubber product.

On the other hand, the rubber product immediately after the molding is completed, as shown in Fig. 2, the product loss, which is a molded part of the fine gap between the upper mold and the lower mold for press, is integrated, and then the product loss formed integrally with the rubber product is removed. After removal work should be done.

However, the press machine as described above has the advantage of being able to mold a large quantity at a time, and the price of the device is low, but on the contrary, the weight of the rubber raw material to be molded into the rubber product must be separately improved before the molding operation. It is difficult to mold rubber products that are structurally complex or large in size, and molds should be designed so that the product loose integrated in the molded rubber products has a thick thickness. Since the original dimensions are kept intact, the rubber raw material is required as much as the amount of the product loss, so that the rubber raw material has a high loss rate.

In addition, by combining the lower die for pressing, on which the weighed rubber raw material pieces on the plate are put into contact with the upper die for pressing, a plurality of rubber products are integrally molded and then press-molded when the molding is completed. Since the product loose, which is the part that does not actually enter the rubber product, is molded together between the rubber products, after removing the molded rubber product, be sure to use a product loss remover made separately from the injection molding machine and the press. By removing the product loss by means of separating the pure rubber products, only a large number of workers are required, as well as a long time to produce a rubber product in perfect condition, as well as the production amount There was also a problem falling significantly.

The present invention has been made in order to solve all the problems that are commonly used injection machine and press machine, by integrating the injection machine and the press machine system to reduce the raw material of the rubber while using only the advantages of the two devices as a rubber product The purpose is to reduce the time taken to complete the molding, and to minimize the number of workers as all the work is done automatically, so that the yield is greatly increased.

Considering that it is installed on the front side, the transporting horizontal movable table 23, along with the transporting vertical moving plate 25 and the mold clamping member 27, toward the press device in the left direction on the drawing as shown in Figs. To move horizontally, The mold clamping member is a state in which the movable mold (1) containing the rubber product in the moldable state is continuously clamped, so that the rubber molded product is finally transferred to the press apparatus by the movable mold. The moving mold 1 is in a state spaced apart above the vertical moving table for presses 15 constituting the press apparatus.

As the mold clamping member 27 for clamping the movable mold 1 containing the pseudo-molded rubber product, any one can be used as long as the movable mold 1 can be clamped. The clamping member 27 It is not a big problem to use a clamp, a vacuum pad, or anything else as the clamp 27a.

On the other hand, while the movable mold (1) containing the molded rubber product is horizontally moved from the injection device side to the press device, it is installed to be horizontally moved forward and backward on the press vertical movable base 15 constituting the press device. The horizontal press 16 for the press is attached to the latter half of the vertical press 15 for the press is moved horizontally forward by receiving the operating force of the horizontal cylinder 17 for the press operated according to the control signal of the control device (Fig. 11), the horizontal movement for the press 16 is moved horizontally forward, when the clamping force of the moving mold (1) moved to the press device in the process described later is released the pressing die horizontal It is intended to be seated while being supported by the belt 32.

11 and 12, when the vertical cylinder 24 for transporting the product transporter operates under the control signal of the control device to push the rod 24a downward, the vertical cylinder 24 for transporting Since the transfer vertical movement plate 25 connected to the rod 24a moves downward under the guidance of each transfer guide bar 26, the mold installed on the lower surface of the transfer movement plate 25 at any moment. The moving mold 1 clamped by the clamp 27a of the clamping member 27 is supported by the horizontal press 16 for the press forming the press apparatus, and at the same time the clamping of the mold clamping member 27 Since the force is released, the movable mold (1) containing the molded rubber product is completed to be seated on the horizontal movable base (16) for pressing as shown in FIG. 13, after which the transport is attached to the horizontal movable base (23). Vertical cylinder 24 controls the controller Since the vertical movement plate 25 is moved vertically as shown in FIG. 14 upward after receiving the arc, the vertical movement table 15 constituting the press apparatus in the subsequent process is moved vertically upward. There is no interference with the vertical conveying plate 25 for forming the apparatus and the mold clamping member 27 provided in the vertical conveying plate for conveying.

In the state as shown in FIG. 14 (the movable mold 1 containing the molded rubber product is seated on the horizontal press 16 for pressing), the press is attached to the latter half of the vertical press 15 for pressing. When the horizontal cylinder 17 is operated by the control signal of the control device and pulls the rod 17a, the horizontal press 16 for the press on which the movable mold 1 is seated is the vertical movable table 15 for the press. 15 is moved to the rear horizontally as shown in Figure 15, the horizontal mold for moving the press 16 in the state that the horizontal movement is completed in the rear movable mold containing a rubber product seated on the horizontal press for molding (1) ) And the center of the press die 18 is located on the same vertical line.

Subsequently, the main cylinder 12 for press fixed to the base 2 is operated by the control signal of the control device to push the rod 12a upward, and the vertical press table 15 for the press moves the main cylinder for the press. Considering that it is connected to the rod 12a of (12), the vertical press for the press 15 is moved vertically upward while being guided to the guide bar 13 for the press, the vertical press for the press 15 When moving vertically upward, the horizontal press 16 for press which is horizontally moved forward and backward on the vertical press for the press and the moving mold 1 seated on the upper surface of the horizontal press for the press together Moving upward is understandable.

On the other hand, the upper surface of the moving mold 1 and the lower surface of the pressing die 18 are hermetically contacted with each other at a moment when the vertical slide table 15 for pressing is moved upward by the main cylinder 12 for pressing. As the mold assembly for a press is formed as described above, from this time, the moldable rubber product contained in the moving mold (1) is pressed and starts to be formed in a complete form. In this case, a part of the raw material of the molded rubber product is pressed. There is no choice but to enter a small gap between the moving mold 1 and the press mold 18 forming the mold assembly for the mold. It is to be understood that is molded together, and the product loss portion is subsequently removed during the take-out.

Immediately after the press mold assembly is made in the above process, the lower heater (not shown) in the horizontal presser 16 for presses and the upper heater (not shown) in the press mold 18 operate to operate 150 to 180. Heated for a certain time (depending on the size and thickness of the rubber product to be molded) to ℃ ℃ the molded rubber product in the press mold assembly is hardened by baking, eventually the rubber product is completely in the shape of the press mold assembly. It will be finished molding.

Since the press main cylinder 12 is operated by the control signal of the control device to pull the rod 12a downwards, the vertical movement table 15 for the press that has been vertically moved upward is the guide bar 13 for the press. While being guided to the vertical movement with the press horizontal movable stage 16 again downwards, at this time, the moving mold (1) seated on the horizontal press for the press is separated from the press die 18 as shown in FIG. The moving mold 1, which is spaced apart from the press die, is filled with a rubber product that has been molded in the press die assembly.

In this state, when the press horizontal cylinder 17 attached to the rear half of the press vertical movable table 15 is operated by the control signal of the control device to push the rod 17a, the press horizontal cylinder 17 Considering that the rod 17a is connected to the horizontal press 16 for press, which is installed on the vertical press 15, the horizontal press for the press is installed on the vertical press 15 for the press. 18 is moved horizontally to the left side in the front view as shown in the figure, the horizontal mold for moving the press 16 is completed in the state that the horizontal mold is completed in the movable mold containing the rubber product is seated on the horizontal movement for the press ( 1) is completely out from the front side on the vertical line of the press die 18 when viewed in a plan view.

Subsequently, when the vertical cylinder 24 for transport attached to the horizontal transport platform 23 constituting the product transport device is operated by the control signal of the control device to push the rod 24a downward, the transport horizontal Below the moving table 23, a vertical moving plate 25 for transfer is installed in the state connected to the rod 24a of the vertical cylinder 24 for transfer, and a moving mold ( Considering that the mold clamping member 27 is installed to clamp 1), the mold clamping member 27 moves vertically downward along with the vertical transfer plate 25 for transporting. At a moment when the mold clamping member 27 moves downward with the 25, the clamp 27a of the mold clamping member is seated on the horizontal press 16 for pressing of the press apparatus as shown in FIG. While contacting the moving mold (1) containing The moving mold is clamped immediately, and after the clamp 27a of the mold clamping member 27 clamps the moving mold 1, the transfer vertical cylinder 24 is operated to pull the rod 24a. As a result, the moving mold 1 clamped to the mold clamping member 27 exits from the horizontal presser 16 for pressing, and is located above the vertical presser 15 for presses on which the horizontal presser for presses is installed. 20 and spaced apart as shown in FIG.

In the above-described operation, the transfer mold (1) containing the molded rubber product seated on the horizontal movable base (16) for press as the transfer vertical moving plate (25) moves downward by the transfer vertical cylinder (24). When the mold clamping member 27 is clamped, the vacuum force is transmitted to the vacuum space 28 formed inside the vertical moving plate 25 for conveying to form a rubber product takeout device. As a result, the inside of the vacuum space is in a vacuum state, and the vacuum force in the vacuum space 28 is blown out to the upper mold 29 for ejecting, which is mounted on the lower surface of the mold clamping member 27 and used for ejecting rubber products. Considering that the plurality of communication holes 30 are formed to act as upper mold grooves formed on the lower surface of the mold upper mold 29, the molded rubber product contained in the movable mold 1 is vacuumed. By suction Due to the landing, it is attached to the upper mold 29 for taking out rather than the moving mold.

Meanwhile, in the same state as in FIGS. 20 and 21, the lead screw 22 installed on the front surface of the fixing bracket 19 constituting the rubber product conveying device receives the reverse driving force of the motor 21 according to the control signal of the control device. When the rotation is reversed, a part is fitted to the guide rail 20 for transporting which is horizontally fixed to the front and the bottom of the fixing bracket 19, and a part is screwed to the lead screw 22. The horizontal transfer table 23 for transporting together with the vertical transporting plate 25 and the mold clamping member 27 for transporting toward the injection device which is in the right direction in the drawing as proportional to the other one-way rotational force of the lead screw 22 And a completely horizontal movement as shown in FIG. 23. In the state as shown in FIGS. 22 and 23, since the mold clamping member 27 is in a state of continuously clamping the moving mold 1, the transfer gold containing the molded rubber product is included. Vertical injection for constituting the injection device can be understood doemeun so positioned in a state spaced above the Dongda 6.

Subsequently, the transfer vertical cylinder 24 constituting the product transfer device is operated by the control signal of the control device to push the rod 24a downward, and is connected to the rod 24a of the transfer vertical cylinder 24. Since the vertical moving plate 25 is installed in the horizontal transfer table 23 for the furnace transfer is moved downward by the guide of each of the transfer guide bar 26 is clamped to the mold clamping member 27 at any moment. The movable mold 1 is supported by the horizontal movable table 7 for forming the injection apparatus, and at the same time, the clamping force of the movable mold 1 by the mold clamping member 27 is released, so that the movable mold is It is seated on the horizontal slide table for injection (7) as shown in FIG. 24, after which the vertical cylinder for transport (24) attached to the horizontal transport table (23) is operated immediately by the control signal of the control device to load ( 24a), so the vertical With a plate 25 clamping the mold member 27 it is again moved upward, as shown in Fig. 25 and 26.

When the vertical movement plate 25 and the mold clamping member 27 move upward as shown in FIGS. 25 and 26, the vacuum inside the vacuum space 28 formed in the vertical movement plate 25 is continuously vacuumed. Since the molded rubber product stuck to the upper mold 29 for ejection has a force, it is stuck to the horizontal movable table 7 for injection in the state as shown in FIGS. It is understood that the movable mold 1 is empty without any rubber products.

25 and 26, when the lead screw 22 installed on the front surface of the fixing bracket 19 rotates forward in one direction by the regular driving force of the motor 21 according to the control signal of the control device, the horizontal for transporting is Shaft 23 is in the direction of the left side in the drawing while being guided by the transfer guide rail 20 in proportion to the forward rotation amount of the lead screw 22 together with the vertical transfer plate 25 and the mold clamping member 27 for transport It moves toward the in press apparatus and stops between the injection apparatus and the press apparatus as shown in Figs. 27 and 28, in which case the support support 31 for constituting the rubber product ejection apparatus in the base 2 between the injection apparatus and the press apparatus. Is fixed, and the lower mold 32 for ejecting is fixed to the upper surface of the ejection support, and the upper mold 29 for ejecting and the ejection upper mold 29 which are fixed to the lower surface of the vertical transfer plate 25 for transporting. Dragon mold (32) is the top and bottom It will keep the spaced apart.

In accordance with the above-described action of the lead screw 22 in accordance with the forward movement of the horizontal transfer table 23, the vertical transfer plate 25 and the mold clamping member 27 together with the guide rail 20 for drawing while drawing The injection-molding horizontal cylinder 8 attached to the rear of the injection-molding base 6 while moving toward the press device in the upper left direction is operated by the control signal of the control device to pull the rod 8a. The horizontal movable seat for injection (7) in which the empty moving mold (1) without the finished rubber product is exited is horizontally moved backwards while being installed on the vertical movable seat (6) for continuous injection by the injection device. Next, the rubber product can be molded.

On the other hand, in the same state as in Figs. 27 and 28 when the vertical cylinder for conveyance constituting the product conveying device operates by the control signal of the control device to push the rod (24a) downward, the vertical conveying cylinder (24) The vertical vertical transfer plate 25 installed on the horizontal transfer table 23 for transport in the state connected to the rod 24a of the movable guide bar 26 is moved downwards by being guided by the guide bar 26 for a certain time. The upper mold 29 for taking out and adsorbing the molded rubber product installed on the vertical movable plate 25 for dispensing while being hermetically contacted with the lower mold 32 for taking out the rubber product as shown in FIG. In the process, the product loss part integrally formed in the molded rubber product is completely separated from the actual rubber product in the take-out mold. Since the inside of the space 28 has a continuous vacuum force, the molded rubber product in a pure state without the product loss part falling out is accommodated in the upper mold groove formed in the lower surface of the upper mold 29 for ejection. It is adsorbed.

After that, the vertical cylinder 24 for conveying the product conveying device is operated by the control signal of the control device and pulls the rod 24a upwards to be connected to the rod 24a of the vertical conveying cylinder 24. Since the vertical transfer plate 25 installed on the horizontal transfer table 23 for moving the furnace is moved upward by the guidance of each transfer guide bar 26, the vertical movement plate 25 is moved to the vertical transfer plate 25 at any moment. The upper mold 29 for taking out and adsorbing the molded rubber product is spaced apart from the lower mold 32 for taking out in a state where only the pure rubber product is adsorbed, as shown in FIGS. 30 and 31. In the lower mold for ejection, the product loss portion remaining from the rubber product remains as it is, and an operator may remove the product loss from the ejection lower mold 32 by using an air injector or artificially.

30 and 31, if the lead screw 22 installed on the front of the fixing bracket 19 in the reverse direction in the other direction by the reverse driving force of the motor 21 according to the control signal of the controller, the horizontal for transport 32 is shown while the guide 23 is guided by the conveying guide rail 20 in proportion to the amount of reverse rotation of the lead screw 22 together with the conveying vertical movable plate 25 and the mold clamping member 27. As shown in FIG. 33, the apparatus is completely moved toward the injection apparatus in the right direction on the drawing, and is positioned at a predetermined interval apart from the vertical moving platform 6 for constituting the injection apparatus. Since the operation of the vacuum force generator that keeps the inside of the vacuum space 28 to be in a vacuum state is stopped, the vacuum force inside the vacuum space is in a released state, and the vacuum force inside the vacuum space 28 is released. State Since the adsorption force of the rubber product adsorbed in the upper mold groove of the upper mold die 29 for ejection is also no longer provided, the rubber product adsorbed on the upper mold mold 29 for ejection is directly dropped downward. do.

The rubber product falling from the upper mold 29 for ejection is a state in which the horizontal mold 7 for injection is mounted on the vertical mold 6 for injection, so that the movable mold 1 is seated horizontally. Considering that it is already moving backward and waiting to mold the next rubber product at, a separate hopper which passes through the injection vertical slide 6 in the vertical direction and is attached to the injection vertical slide (Not shown) is temporarily collected and the collected rubber products are taken out to one place and collected in the collecting container, and all the processes of forming the rubber products are finished, and the molding process of the rubber products is performed while the whole system is in operation. It is understandable that the rubber product is continuously molded over and over again.

In the embodiment of the present invention described above, the injection molding apparatus and the molding of the rubber product by the injection molding the rubber raw material in a quantitative supply as a whole system, and the rubber product molded by the injection device is pressed to transfer the complete form Press apparatus for molding into rubber products, and rubber for conveying the rubber products molded by the injection apparatus to the press apparatus or for transporting the rubber products molded in the complete form by the press apparatus to another place. A product conveying device, and a rubber product extracting device which is formed in combination with some components of the rubber product conveying device to remove each product of the rubber product from which the product loss is removed while removing the product loss of the molded rubber product; When molding the rubber product by the injection device, It is used as a component, and when molding a rubber product molded by a press device into a rubber product of a complete form, it is used as a component of a mold assembly for a press. When transporting to take out a rubber product molded in a complete form, the injection mold used as a mold for transporting rubber products is a basic configuration, but is not limited thereto, and other press apparatuses having the same function as the press apparatus may include the injection apparatus. It may be provided to be spaced apart on the other side of one to use a single injection device and two press devices, in this case, the rubber product transfer device and the rubber product take out device each requires two.

In the above, one injection apparatus and two press apparatuses may be used in combination. Since the injection apparatus only needs to temporarily mold the rubber product, the time required for the temporary molding of the rubber product is short, but the press apparatus is temporarily molded. Since the rubber product must be completely molded, it takes longer to bake at a high temperature in order to completely form the molded rubber product (the size of the molded rubber product, the presence or absence of other metallic members inserted therein, etc.). The baking time varies.) It is understood that the production capacity can be improved by using a single injection unit and two press units in combination.

Therefore, in the present invention, since only the rubber product is molded in the injection apparatus, and the press device only completely molds the molded rubber product, the advantages of the injection apparatus and the advantage of the press apparatus can be utilized. Since the rubber raw material to be molded enters only the exact amount necessary for molding the actual rubber product, it is possible to reduce the raw material, and as described above, the injection device does not completely mold the rubber product, but only moldability, so There is no runner loss because the rubber product does not have the inlet part, which is the part where the rubber raw material is injected into the injection mold assembly, and the press machine only serves to receive the molded rubber product so that it can be completely molded. There is almost no product loss.

In addition, since the rubber product in the completely molded state is automatically taken out by the press device, there is no inconvenience of artificially taking out the rubber product as in the prior art, and the rubber product in the taken out state is finished with the product part cut off and separated. Therefore, as in the prior art, the product loose part of the molded rubber product is cut and removed by a separate product loose cutting press, or there is no inconvenience to remove it by hand manually, thereby improving workability and increasing production. There is also a cost saving effect.
