Description

Technical Field

[0001] The invention belongs to the technical field of injection molding devices, and in particular relates to a modular high-performance two-plate injection molding device. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. The two-plate injection molding device is an injection molding device that uses two templates to form a closed cavity and then injects material into it.

[0003] The existing two-plate injection molding device usually needs to separate the plastic product from the mold after it is formed. Due to the influence of thermal expansion and contraction, the plastic product is usually easily clamped outside the convex template after solidification. The existing separation method generally used is to separate the plastic product from the convex template by a telescopic push rod. However, since some plastic products are relatively thick, their surfaces are not completely solidified after cooling, and the connection between the plastic product and the convex template is too tight, which easily forms an indentation on the surface of the plastic product during separation; Another separation method is to use air pressure to push the plastic product and the convex template apart. However, in order to ensure that the molding is completed, the air holes reserved on the convex template are generally small, and the plastic product is tightly attached to the convex template, so a large air pressure is required to push the plastic product and the convex template apart. After separation, the plastic product is easily ejected by the air pressure and collides with other mechanisms, thereby affecting the appearance quality of the plastic product after molding. Summary of the invention

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

A guide rod 15 is fixedly connected in the shell 2, and a movable mold 14 is horizontally slidably connected to the guide rod 15. A No. 1 electric push-pull rod 16 is connected between the movable mold 14 and the fixed frame on the upper part of the shell 2. A cooling system 6 connected to the fixed mold 13 and the movable mold 14 is arranged in the shell 2; The movable mold 14 is provided with a cavity 17, and a thrust mechanism 7 is provided in the cavity 17. The thrust mechanism 7 can push out the molded product outside the movable mold 14. An air pump 18 is provided in the cavity 17. Suction mechanisms 8 are provided on both side walls of the housing 2. Two suction mechanisms 8 are provided on both sides of the movable mold 14. The suction mechanisms 8 can pull out the molded product on the movable mold 14 by adsorption force. A limiting component 9 is connected to the suction mechanism 8. The limiting component 9 can protect the molded product during the process of pulling out the molded product. The control system can control the appearance quality of the molded product by controlling the boost system 5, the cooling system 6, the thrust mechanism 7, the suction mechanism 8 and the limit assembly 9.

[0031] In this embodiment, driven by the No. 1 electric push-pull rod 16, the movable mold 14 moves toward the fixed mold 13 along the guide rod 15, and the movable mold 14 is sealed and connected with the fixed mold 13; when in use, the plastic particles are injected into the feed pipe 10 through the guide funnel 11, and the plastic particles form a fluid in the feed pipe 10 under the heating action of the heating system 12, and the feed mechanism 4 is started at this time, and the feed mechanism 4 pushes the plastic fluid in the feed pipe 10 into the closed cavity formed by the fixed mold 13 and the movable mold 14; the booster system 5 moves along the inside of the feed pipe 10 and pushes the plastic fluid in the feed pipe 10, so that the fixed mold 13 and the movable mold 14 are filled with plastic fluid, and the pressure between the fixed mold 13 and the movable mold 14 is maintained; Then, the fixed mold 13 and the movable mold 14 are kept sealed and stationary, and the cooling system 6 drives the coolant to circulate in the side walls of the fixed mold 13 and the movable mold 14, so that the plastic fluid in the fixed mold 13 and the movable mold 14 is quickly cooled and solidified; After the fixed mold 13 and the movable mold 14 have been stationary for a period of time, the No. 2 electric push-pull rod 23 is started to drive the movable mold 14 away from the fixed mold 13. At this time, the plastic fluid in the fixed mold 13 and the movable mold 14 solidifies into a molded product. Under the principle of thermal expansion and contraction, the molded product is sleeved on the outside of the movable mold 14; the thrust mechanism 7 is started to push the molded product and the movable mold 14 to separate.

[0032] When the molded product is too tightly combined with the movable mold 14, if the thrust mechanism 7 increases the thrust, it is easy to leave an indentation on the surface of the molded product. At this time, the thrust mechanism 7 moves backward, and the No. 1 air pump 18 in the cavity 17 applies air pressure thrust to the molded product. At the same time, the suction mechanism 8 can pull the molded product on the movable mold 14 out through the adsorption force, and the limiting component 9 protects the molded product during the process of pulling out the molded product.

[0033] like Figure 2 As shown, it is a modular high-performance two-plate injection molding device provided by the present invention, wherein the feeding mechanism 4 includes a No. 1 motor 41, a three-stage screw push rod 42 and a material guide head 43; The No. 1 motor 41 is fixedly connected to the boost system 5 , the output shaft of the No. 1 motor 41 is connected to one end of a three-stage screw push rod 42 , and the other end of the three-stage screw push rod 42 is fixedly connected to a guide head 43 , and the guide head 43 is unidirectionally conductive to the liquid outlet end of the feed pipe 10 .

[0034] In this embodiment, the No. 1 motor 41 is started, and the No. 1 motor 41 drives the three-stage screw push rod 42 to rotate. The three-stage screw push rod 42 pushes the plastic fluid in the feed pipe 10 forward. At this time, the guide head 43 introduces the plastic fluid into the cavity between the fixed mold 13 and the movable mold 14 in a unidirectional manner.

[0035] like Figure 3 As shown, it is a modular high-performance two-plate injection molding device provided by the present invention, wherein the boosting system 5 includes a hydraulic cylinder 51, a slide plate 52, a fluid pump 53 and a push block 54; A hydraulic cylinder 51 is fixedly installed in the movable platform 3, a slide plate 52 is slidably and sealedly connected in the hydraulic cylinder 51, the hydraulic cylinder 51 is connected to the hydraulic box through a fluid pump 53, the No. 1 motor 41 is fixedly connected to the slide plate 52, and a push block 54 is rotatably connected to the three-stage spiral push rod 42, and the push block 54 is slidably and sealedly connected to the inner wall of the feed pipe 10.

[0036] In this embodiment, the fluid pump 53 is started, and the fluid pump 53 pushes the hydraulic oil in the hydraulic box into the hydraulic cylinder 51. The hydraulic oil pushes the slide plate 52 to slide along the hydraulic cylinder 51. The slide plate 52 drives the hydraulic cylinder 51 to move forward. The hydraulic cylinder 51 drives the push block 54 to move into the feed pipe 10. The feed pipe 10 is unidirectionally connected to the fixed mold 13, so that the fluid pressure of the plastic fluid between the fixed mold 13 and the movable mold 14 is increased by the liquid pressure of the hydraulic oil, thereby avoiding poor appearance quality of the molded product.

[0037] like Figure 5 As shown, it is a modular high-performance two-plate injection molding device provided by the present invention, wherein the thrust mechanism 7 includes a first electric push rod 71, a positioning plate 72 and a second electric push rod 73; A positioning plate 72 is slidably and sealedly connected in the movable mold 14, and a plurality of No. 1 electric push rods 71 ​​are fixedly connected to the positioning plate 72, and the telescopic end of the No. 1 electric push rod 71 is flush with the outer end surface of the movable mold 14, and a No. 2 electric push rod 73 is fixedly connected to the outer end surface of the movable mold 14, and the telescopic end of the No. 2 electric push rod 73 is fixedly connected to the positioning plate 72; The telescopic end of the first electric push rod 71 is fixedly connected with a boss 24 , a spring 25 is arranged between the boss 24 and the inner end surface of the cavity 17 , and a pressure sensor is arranged between the boss 24 and the spring 25 .

[0038] In this embodiment, when the cooling system 6 drives the circulating cooling water to cool the fixed mold 13 and the movable mold 14, the movable mold 14 is separated from the fixed mold 13, and the No. 1 electric push rod 71 is started. The No. 1 electric push rod 71 pushes the molded product to separate from the movable mold 14, and at the same time, the No. 1 electric push rod 71 drives the boss 24 to squeeze the spring 25; When the thrust of the No. 1 electric push rod 71 is insufficient and the molded product cannot be separated from the movable mold 14, the pressure of the pressure sensor remains unchanged, the control system receives the signal and controls the No. 2 electric push rod 73 to contract, and all the No. 1 electric push rods 71 ​​are reset. At this time, the No. 2 electric push rod 73 drives the positioning plate 72 to slide along the cavity 17, and the No. 1 electric push rod 71 is released from contact with the movable mold 14. At the same time, the No. 1 air pump 18 is started, and the No. 1 air pump 18 increases the air pressure in the cavity where the No. 1 electric push rod 71 is located, and the air pressure is used to push the molded product to separate from the movable mold 14.

[0039] like Figure 6 As shown, a modular high-performance two-plate injection molding device provided by the present invention is provided with a guide channel 26 in the side wall of the movable mold 14 in contact with the molded product, and an annular cavity 22 is provided in the side wall of the movable mold 14 around the telescopic end of the No. 1 electric push rod 71, and all the annular cavities 22 are connected to the guide channel 26, and a circulating water cooling circuit is formed between the cooling system 6 and the guide channel 26.

[0040] In this embodiment, the cooling system 6 drives the circulating water to flow in the annular cavity 22 and the guide channel 26. The setting of the guide channel 26 allows the plastic fluid in the area near the No. 1 electric push rod 71 to accelerate cooling and solidification, thereby avoiding the formation of indentations on the surface of the molded product when the No. 1 electric push rod 71 is pushed.

[0041] like Fig. 9 As shown, it is a modular high-performance two-plate injection molding device provided by the present invention, wherein the suction mechanism 8 includes a sliding seat 81, a transmission motor 82, an electric telescopic plate 83, an electric telescopic rod 84 and a suction cup 85; The sliding seat 81 is horizontally slidably connected to the inner wall of the outer shell 2, and a transmission motor 82 is fixedly arranged on the inner wall of the outer shell 2. The sliding seat 81 is threadedly connected to the output shaft of the transmission motor 82. The sliding seat 81 is fixedly connected to an electric telescopic plate 83, and the telescopic end of the electric telescopic plate 83 is fixedly connected to an electric telescopic rod 84. The telescopic end of the electric telescopic rod 84 is fixedly connected to a suction cup 85, and the suction cup 85 is connected to the No. 2 air pump 19 through a conduit.

[0042] In this embodiment, when the thrust of the No. 1 electric push rod 71 is insufficient and the molded product cannot be separated from the movable mold 14, the pressure of the pressure sensor remains unchanged at this time, the control system receives the signal and controls all the electric telescopic plates 83 to extend, and the electric telescopic plates 83 drive the suction cup 85 to approach the molded product. When the suction cup 85 is facing the end face of the molded product, the electric telescopic rod 84 is started at this time, and the electric telescopic rod 84 pushes the suction cup 85 to be sucked tightly against the surface of the molded product, and then the No. 2 air pump 19 is started, and the No. 2 air pump 19 simultaneously extracts the air in all the suction cups 85 through the conduit, thereby forming a negative pressure in the suction cups 85, further enhancing the adsorption force between the suction cups 85 and the surface of the molded product; the transmission motor 82 is started, and the transmission motor 82 drives the sliding seat 81 to slide horizontally along the inner wall of the shell 2 through the threaded transmission, and the sliding seat 81 drives the suction cup 85 to pull the molded product out of the movable mold 14; The air pressure thrust of the No. 2 air pump 19 and the pulling force of the suction cup 85 jointly separate the molded product from the movable mold 14, while at the same time being able to have no rigid contact with the molded product to avoid surface damage to the molded product; when the suction cup 85 pulls the molded product, negative pressure is easily generated between the molded product and the movable mold 14, thereby increasing the separation resistance between the movable mold 14 and the molded product. The air pressure thrust of the No. 2 air pump 19 can avoid the generation of negative pressure between the molded product and the movable mold 14, further increasing the separation efficiency between the molded product and the movable mold 14.

[0043] like Figure 8 as well as Fig. 9 As shown, it is a modular high-performance two-plate injection molding device provided by the present invention, wherein the limiting assembly 9 includes an elastic limiting frame 91, an elastic telescopic plate 92 and a limiting seat 93; The telescopic end of the electric telescopic plate 83 is fixedly connected to an elastic limit frame 91, one end of the elastic limit frame 91 is fixedly connected to an elastic telescopic plate 92, one end of the elastic telescopic plate 92 is fixedly connected to a limit seat 93, and the limit seat 93 has an inclined surface facing the molded product.

[0044] In this embodiment, when the electric telescopic plate 83 extends and drives the suction cup 85 to approach the molded product, the electric telescopic plate 83 drives the elastic limit frame 91 to move at the same time, and the elastic limit frame 91 drives the limit seat 93 to abut against the joint between the molded product and the movable mold 14 in advance. The elastic thrust of the limit seat 93 on both sides of the molded product can first form a certain gap between the molded product and the movable mold 14, so as to avoid that the air pressure thrust of the second air pump 19 is too small to contact the molded product at the beginning and form an effective thrust; When the molded product moves forward with the suction cup 85, the limit seat 93 abuts against the side wall of the molded product under the elastic thrust of the elastic telescopic plate 92, and both ends of the molded product are limited by the limit seat 93 and the suction cup 85 to prevent the suction cup 85 from detaching from the movable mold 14 during the movement, thereby preventing the molded product from colliding with the movable mold 14.

[0045] like Figure 8 as well as Fig. 9 As shown, it is a modular high-performance two-plate injection molding device provided by the present invention, wherein an airbag 20 is arranged in the limiting seat 93, and an opening for the airbag 20 to pop out is arranged on the inclined surface of the limiting seat 93, and all the airbags 20 are commonly connected to a No. 3 air pump 21.

[0046] In this embodiment, when the transmission motor 82 drives the sliding seat 81 to start moving, the control system controls the No. 3 air pump 21 to start, and the No. 3 air pump 21 pressurizes all the air bags 20, and the air bags 20 pop out to the outside of the limit seat 93. At this time, the air bags 20 abut against the connection between the movable mold 14 and the molded product, so as to increase the stability of the molded product when it is separated from the movable mold 14; When the molded product is completely separated from the movable mold 14, the airbag 20 can be quickly filled into the gap between the molded product and the movable mold 14 under the push of air pressure, thereby preventing the molded product from vibrating back and forth when the molded product is completely separated from the movable mold 14, causing damage to the edges of the molded product and the movable mold 14 due to collision.

[0047] like Fig.11 As shown, the control system comprises: The monitoring module includes: a pressure monitoring unit for monitoring the pressure of the plastic fluid between the fixed mold 13 and the movable mold 14 during molding, the pressure monitoring unit includes a hydraulic sensor, the hydraulic sensor is arranged in the inner cavity formed between the slide plate 52 and the hydraulic cylinder 51, and the inner cavity is connected to the fluid pump 53; a temperature monitoring unit for monitoring the cooling degree of the molded product after molding, the temperature monitoring unit includes a temperature sensor, and the temperature sensor is connected to the outer wall of the movable mold 14; and a thrust monitoring unit for monitoring the thrust of the molded product by the thrust mechanism 7 after molding, the thrust monitoring unit includes a current transformer, and the current transformer is used to monitor the control current of the No. 1 electric push rod 71, so as to calculate the thrust value of the No. 1 electric push rod 71; A judgment module, which is used to compare the hydraulic pressure value F of the hydraulic sensor, the temperature value T of the temperature sensor, and the thrust value f of the first electric push rod 71 obtained by the monitoring module with the corresponding first preset threshold ranges in the judgment module, and generate a corresponding control instruction if at least one of them exceeds the corresponding first preset threshold range; The evaluation module is used to summarize the hydraulic pressure value F obtained by the monitoring module, the temperature value T of the temperature sensor, and the thrust value f of the No. 1 electric push rod 71 to form detection condition information, build a data model and optimize and train it, and perform regression analysis on the obtained hydraulic pressure value F, temperature value T, and thrust value f through analysis software to obtain the influence of the hydraulic pressure value F, temperature value T, and thrust value f on the appearance quality of the molded product, and output the speed influence factor AF, pressure influence factor AT, and angle influence factor Af; perform dimensionless processing on the hydraulic pressure value F, temperature value T, and thrust value f, and associate them to form a control coefficient ZW, and its association model is: Where AF is the hydraulic pressure factor, , AT represents the temperature factor, , Af represents the thrust factor, ; The acquired control coefficient is transmitted to the judgment unit for comparison with a preset second preset threshold range. If the control coefficient is not within the range of the second preset threshold, a corresponding control instruction is generated.

[0048] The control module is used to control the boost system 5, the cooling system 6, the thrust mechanism 7, the suction mechanism 8 and the limit assembly 9.

[0049] The judgment module and the evaluation module both perform judgment and evaluation through a computer processor, and the control module is a PLC controller.

[0050] In this embodiment, when the pressure value of the plastic fluid between the fixed mold 13 and the movable mold 14 exceeds the first preset threshold range in the judgment module during molding, the control module controls the fluid pump 53 to start the adjustment, and changes the hydraulic thrust of the plastic fluid in the feeding pipe 10 through the fluid pump 53, thereby changing the pressure of the plastic fluid between the fixed mold 13 and the movable mold 14, so as to avoid the surface of the molded product being concave due to the plastic fluid pressure between the fixed mold 13 and the movable mold 14 being too low or the molded product being difficult to be quickly separated from the movable mold 14 after molding due to the excessive pressure of the plastic fluid between the fixed mold 13 and the movable mold 14; When the temperature value of the temperature sensor after the molded product is formed exceeds the first preset threshold range in the judgment module, it means that the molded product is not completely cooled and solidified. At this time, the control module controls the cooling system 6 to increase the power, thereby improving the cooling and solidification speed of the molded product in subsequent production; When the thrust value of the No. 1 electric push rod 71 when pushing the molded product exceeds the first preset threshold range in the judgment module, it is easy to form an indentation on the surface of the molded product. The control module controls the control current of the No. 1 electric push rod 71 to decrease, thereby reducing the thrust value of the No. 1 electric push rod 71 when pushing the molded product; The molded product is subjected to appearance inspection after molding. If the appearance quality of the molded product does not meet the requirements, the control coefficient in the evaluation module is adjusted at this time to control the appearance quality of the molded product.
