Description

Technical Field

[0001] This invention relates to the field of parts processing equipment technology, and in particular to a parts injection molding and stamping composite molding device and method. Background Technology

[0002] Injection molding of parts involves injecting molten plastic into a carefully designed mold cavity, enabling rapid mass production of parts with complex shapes and diverse structures, greatly improving production efficiency. At the same time, injection molding can use a variety of plastic raw materials with different properties to meet the diverse needs of parts in terms of strength, toughness, corrosion resistance, etc. While injection molding can quickly inject molten plastic into a mold to form parts of a specific shape, the molded parts may have deficiencies in terms of dimensional accuracy, surface quality, and local structural strength. Stamping, on the other hand, can perform secondary processing on injection molded parts by means of precise force control and mold action, further correcting dimensional deviations, improving surface flatness and smoothness, and strengthening the strength and rigidity of local weak areas, so that the parts can better meet design requirements and actual use needs, and ensure the stability and reliability of product quality. Currently, most parts injection molding and stamping operations need to be carried out separately. After the parts are injection molded, they undergo a series of processes such as cooling, and then are transferred to the stamping station by a transfer mechanism to complete the stamping. As a result, the parts need a long time to cool after injection molding, while the stamping processing time is generally short. Therefore, there will be a long downtime, resulting in low overall processing efficiency and making it impossible to quickly and continuously perform composite molding processes of injection molding and stamping. Summary of the Invention

[0003] The purpose of this invention is to provide a device and method for injection molding and stamping composite molding of parts, which can ensure the synchronous execution of multiple processes through the provided mechanism, thereby shortening the downtime of the entire processing system and greatly improving the processing efficiency of injection molding and stamping composite molding.

Each mounting plate is provided with two adapters, which are adapted to the two end connectors of the inner circulation channel. The output end of the control cylinder is connected to the mounting plate, and the control cylinder is mounted on the work frame. The flow-changing component is connected to the work frame and is used for liquid storage and diversion.

[0007] The conversion component includes a flipping clamp, a flipping motor, and a rotation component. The flipping clamp is rotatably mounted on the side of the work frame near the stamping mechanism. The output shaft of the flipping motor is connected to the flipping clamp, and the flipping motor is fixedly mounted on one side of the work frame. The rotation component is connected to the processing frame and is used to complete the station transfer after the demolded plastic part is demolded.

[0008] The pushing component includes a lowering bracket and a lead screw lowering mechanism. The lowering bracket is slidably mounted above the work frame. The lead screw lowering mechanism is connected to the work frame and is used to drive the lowering bracket to move.

[0009] The converter includes a liquid storage tank, a temperature sensing mechanism, a semiconductor heat exchange mechanism, and a pump body. Two liquid storage tanks are installed within the working frame, and each tank is connected to one of the adapters mounted on the mounting plates on both sides via a conduit. Each tank is equipped with a temperature sensing mechanism for monitoring the liquid temperature inside. The semiconductor heat exchange mechanism is connected to the two tanks and controls the liquid temperature within them. Two pump bodies are installed within the working frame, with their outlets connected to the two tanks respectively, and their inlets connected via conduits to one of the adapters not currently connected to the mounting plates on both sides.

[0010] The indexing component includes an indexing frame, an indexing motor, and a pressing table. The indexing frame is rotatably mounted on the processing frame. The output shaft of the indexing motor is connected to the indexing frame, and the indexing motor is mounted on the processing frame. The two pressing tables are slidably mounted on both sides of the indexing frame.

[0011] The converter component further includes an upper sealing plate, a screw sealing mechanism, an air pump, and a one-way valve.

The injection molding of the parts is completed by the injection molding mechanism in conjunction with the cavity plate set on the turntable; When the injection molding is completed, the main rotary motor will drive the turntable to rotate. As the turntable rotates, the cavity plate located at the injection station will be transferred to the cooling station. The cavity plate located in the cooling station is cooled by the set temperature control component. After cooling, the main motor drives the turntable to rotate again. The cooled cavity plate is transferred to the demolding station by the rotation of the turntable, and then the demolding of the plastic part is completed with the help of the ejector component. The plastic part detached from the cavity plate will be transferred to the stamping station by the action of the conversion component. After demolding, the cavity plate will rotate again with the turntable and then be transferred to the preheating station.

[0014] This invention discloses a composite molding apparatus and method for injection molding and stamping of parts. In actual operation, the injection molding mechanism, in conjunction with the cavity plate mounted on the turntable, completes the injection molding of the part. Upon completion of injection molding, the main motor drives the turntable to rotate. As the turntable rotates, the cavity plate located at the injection station is transferred to the cooling station. A temperature control component cools the cavity plate at the cooling station. After cooling, the main motor drives the turntable to rotate again, transferring the cooled cavity plate to the demolding station. With the assistance of an ejector component, the part is demolded. The demolded part is then transferred to the stamping station by a transfer component. After demolding, the cavity plate rotates again with the turntable and is transferred to the preheating station. The cavity plate at the preheating station is then heated by the temperature control component. Preheating is achieved under the action of the component. When the turntable rotates again, the cavity plate in the preheating station will transfer to the injection molding station for injection molding. In this way, by adopting a four-station cyclic injection molding structure of injection molding, cooling, demolding and preheating, and with the help of the conversion component, the rapid conversion between the injection molding and stamping stations can be completed. Injection molding, cooling, preheating and stamping can be carried out simultaneously. When the cavity plate in the injection molding station is performing injection molding, the cavity plate in the cooling station will cool the molded plastic part. The cavity plate in the demolding station will switch between the injection molding and stamping stations. As for the cavity plate in the preheating station, it will be preheated under the action of the temperature control component. This allows the entire process to avoid long downtime as much as possible. The mechanism ensures the synchronous operation of multiple processes, thereby shortening the downtime of the entire processing system and greatly improving the processing efficiency of injection molding and stamping composite molding.

Detailed Implementation

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Please see Figures 1 to 9 This invention provides a composite molding device for injection molding and stamping of parts: including a processing frame 101, a stamping mechanism 102, a work frame 103, an injection molding mechanism 104, and a composite component. The composite component includes a turntable 105, a main motor 106, a cavity plate 107, a transition arc block 108, an ejector component, a temperature control component, and a conversion component. The ejector component includes an ejector frame 201, a return spring 202, and a downward pushing component. The temperature control component includes a circulation inner channel 301, a mounting plate 302, an adapter joint 303, a control cylinder 304, and a flow conversion component. The conversion component includes a flipping clamp 401, a flipping motor 402, and a rotation component. The downward pushing component includes a downward moving bracket 501 and a lead screw downward moving mechanism 502. The flow conversion component includes a liquid storage tank 601 and a temperature... The system includes a temperature sensing mechanism 602, a semiconductor heat exchange mechanism 603, and a pump body 604. The indexing component includes an indexing frame 701, an indexing motor 702, and a pressing table 703. The commutation component also includes an upper sealing slide plate 605, a lead screw upper sealing mechanism 606, an air pump 607, and a one-way valve 608. The aforementioned solution solves the problem that existing parts injection molding and stamping processes mostly require separate segmented operations. After the parts are injection molded, they undergo a series of treatments such as cooling, and then are transferred to the stamping station through a transmission mechanism to complete the stamping. As a result, the parts need a long time to cool after injection molding, while the stamping processing time is generally short, thus resulting in a long downtime, leading to low overall processing efficiency and the inability to quickly and continuously perform composite molding processes of injection molding and stamping.

[0030] Furthermore, the stamping mechanism 102 is mounted on the processing frame 101, the work stand 103 is fixedly mounted on the processing frame 101, the injection molding mechanism 104 is mounted on the work stand 103, the turntable 105 is rotatably mounted inside the work stand 103, the output shaft of the main motor 106 is connected to the turntable 105 to drive the turntable 105 to rotate, and four cavity plates 107 are rotatably mounted on the turntable 105. The transition arc block 108 is fixedly installed on each side. The transition arc block 108 is rotatably connected to the turntable 105 and cooperates with the arc-shaped guide rail provided on the inner side of the work frame 103. The ejector component and the cavity plate 107 are used to eject the molded plastic part. The temperature control component and the cavity plate 107 are used to regulate the temperature inside the cavity plate 107. The conversion component is connected to the work frame 103 and is used to complete the state conversion of the cavity plate 107 at the corresponding work station.

[0031] Specifically, the stamping mechanism 102 consists of a corresponding stamping plate and a pressing power element, while the injection molding mechanism 104 consists of a corresponding injection system and a control system, so that the granular plastic is heated and melted, and then injected rapidly under high pressure into the closed cavity plate 107 through the injection system. The cavity plate 107 is provided with a corresponding mold cavity, and there are a total of four sets of cavity plates 107, which are evenly distributed on the turntable 105.

[0032] The turntable 105 is driven by the main motor 106. The transition arc block 108 is fixed on the outside of the cavity plate 107. The work frame 103 is provided with an arc groove for the transition arc block 108 to rotate, so that the cavity plate 107 can rotate stably with the turntable 105 in the work frame 103.

[0033] In actual operation, the injection molding mechanism 104, in conjunction with the cavity plate 107 mounted on the turntable 105, completes the injection molding of the part. Upon completion of injection molding, the main motor 106 drives the turntable 105 to rotate. As the turntable 105 rotates, the cavity plate 107 located at the injection station is transferred to the cooling station. A temperature control component cools the cavity plate 107 at the cooling station. After cooling, the main motor 106 then... The turntable 105 rotates again, and the cooled cavity plate 107 is transferred to the demolding station by the rotation of the turntable 105. Then, with the help of the ejector component, the plastic part is demolded. The plastic part detached from the cavity plate 107 is transferred to the stamping station by the action of the conversion component. After demolding, the cavity plate 107 will rotate again with the turntable 105 and then be transferred to the preheating station. The cavity plate 107 located in the preheating station will... Preheating is performed under the action of the temperature control component. When the turntable 105 rotates again, the cavity plate 107 in the preheating station will transfer to the injection molding station for injection molding. In this way, by adopting a four-station cyclic injection molding structure of injection molding, cooling, demolding and preheating, and with the cooperation of the conversion component to complete the rapid conversion between the injection molding and stamping stations, injection molding, cooling, preheating and stamping can be carried out simultaneously. When the cavity plate 107 in the injection molding station is performing injection molding, the cavity plate 107 in the cooling station will cool the molded plastic part, and the cavity plate 107 in the demolding station will switch between the injection molding and stamping stations. As for the cavity plate 107 in the preheating station, it will be preheated under the action of the temperature control component, so that the entire process can avoid long downtime as much as possible. The mechanism can ensure the synchronous operation of multiple processes, thereby shortening the downtime of the entire processing system and greatly improving the processing efficiency of injection molding and stamping composite molding.

[0034] Furthermore, the ejector frame 201 is slidably installed inside the cavity plate 107; the two sides of the return spring 202 are respectively connected to the ejector frame 201 and the cavity plate 107; the push-down component is connected to the work frame 103 and is used to squeeze and push the ejector frame 201 out at a designated position.

[0035] Furthermore, the lowering bracket 501 is slidably mounted above the work frame 103; the lead screw lowering mechanism 502 is connected to the work frame 103 and is used to drive the lowering bracket 501 to move.

[0036] In this embodiment, each cavity plate 107 is provided with an ejector frame 201. The ejector frame 201 consists of a movable plate and an ejector rod. In actual design, a corresponding ejection structure can be set according to the cavity plate 107 of different types. The ejector frame 201 is provided with a return spring 202 in the area where it cooperates with the cavity plate 107. When it is necessary to eject the molded plastic part for demolding, the ejector frame 201 needs to squeeze the return spring 202 to move. After demolding is completed, the ejector frame 201 can spring back to its original position under the action of the return spring 202.

[0037] Both the lowering bracket 501 and the lead screw lowering mechanism 502 are located on the demolding station. The lead screw lowering mechanism 502 consists of a lead screw and a motor that drives the lead screw to rotate, so that the corresponding plate can be driven by the rotation of the corresponding lead screw, and then the ejector 201 on the demolding station is pressed down and pushed out by driving the lowering bracket 501 to move down.

[0038] Furthermore, the circulating inner channel 301 is disposed within the cavity plate 107; two mounting plates 302 are slidably mounted on both sides of the work frame 103; each mounting plate 302 is provided with two adapter joints 303, which are adapted to the two end joints provided in the circulating inner channel 301; the output end of the control cylinder 304 is connected to the mounting plate 302, and the control cylinder 304 is mounted on the work frame 103; the flow exchange component is connected to the work frame 103 for storing and draining liquid.

[0039] Furthermore, two liquid storage tanks 601 are installed inside the work frame 103, and the two liquid storage tanks 601 are connected to one of the adapters 303 installed on the mounting plates 302 on both sides through conduits; each liquid storage tank 601 is provided with a temperature sensing mechanism 602 for monitoring the liquid temperature inside the liquid storage tank 601; the semiconductor heat exchange mechanism 603 is connected to the two liquid storage tanks 601 for controlling the liquid temperature inside the two liquid storage tanks 601; two pump bodies 604 are installed inside the work frame 103, the water outlets of the two pump bodies 604 are respectively connected to the two liquid storage tanks 601, and the liquid inlet ends of the two pump bodies 604 are respectively connected to one of the adapters 303 on the mounting plates 302 on both sides that are not connected through conduits.

[0040] Furthermore, the upper sealing slide plate 605 is slidably installed on both of the liquid storage tanks 601; the screw upper sealing mechanism 606 is arranged in a one-to-one correspondence with the upper sealing slide plate 605, and the upper sealing slide plate 605 is driven by the screw upper sealing mechanism 606; the two air pumps 607 are respectively connected to the conduits that connect the adapter joints 303 on both sides to the liquid storage tanks 601, and each air pump 607 is provided with a one-way valve 608 at the air outlet end.

[0041] In this embodiment, each cavity plate 107 is provided with a circulating inner channel 301. The circulating inner channel 301 has two interfaces, and the adapter 303 on the mounting plate 302 facilitates the mating of the two interfaces of the circulating inner channel 301. Two sets of mounting plates 302 and adapters 303 are respectively installed at the cooling station and the preheating station. The mounting plates 302 are driven by the control cylinder 304. When the cavity plate is located at the cooling station or the preheating station... When the cavity plate 107 needs cooling and preheating, the control cylinder 304 will drive the mounting plate 302 to move upward, and then drive the adapter 303 to connect to the two interfaces of the circulation channel 301 respectively. When the cavity plate 107 needs to perform the next station change, the control cylinder 304 will drive the mounting plate 302 to move downward, so as to remove the two adapters 303 set on the mounting plate 302 and avoid interfering with the station change of the cavity plate 107.

[0042] The two adapters 303 on the mounting plate 302 are connected to the corresponding liquid storage tank 601 and the inlet end of the pump body 604 respectively via conduits. The adapters 303 on both sides of the mounting plate 302 are respectively connected to the two liquid storage tanks 601, and the two pump bodies 604 are also respectively connected to the two liquid storage tanks 601. The two liquid storage tanks 601 are used to store cold water and hot water respectively. Each of the two liquid storage tanks 601 is equipped with a temperature sensing mechanism 602, which is a temperature sensor. The temperature sensing mechanism 602 can monitor the liquid temperature inside the two liquid storage tanks 601. When the adapters 303 on both sides of the mounting plate 302 are respectively connected to the two cavities... After the internal circulation channel 301 inside the plate 107 is connected, the two pumps 604 will introduce the liquid inside the corresponding liquid storage tank 601 into the circulation channel 301, so that the liquid storage tank 601 containing cold water will continuously introduce cold water into the corresponding circulation channel 301 to complete the cooling of the corresponding cavity plate 107. Then, the liquid that has absorbed heat and heated up will be introduced into the liquid storage tank 601 containing hot water, and the liquid storage tank 601 containing hot water will also continuously introduce hot water into the corresponding circulation channel 301 to complete the preheating of the corresponding cavity plate 107. After that, the cooled water will be introduced into the liquid storage tank 601 containing cold water. In this way, the heat output during the molding and cooling process of the plastic part can be fully utilized.

[0043] Meanwhile, the liquid storage tanks 601 on both sides are also equipped with the semiconductor heat exchange mechanism 603. The semiconductor heat exchange mechanism 603 mainly consists of a semiconductor cooling plate and a power control system. The semiconductor cooling plate (Thermoelectric Cooler, TEC) is a type of thermoelectric cooler based on the Peltier effect. The solid-state cooling device (Effect) has a core structure consisting of N-type and P-type semiconductor materials connected in series by a metal conductor to form thermocouple pairs. Through a large number of these thermocouple pairs, the cold end continuously absorbs heat and cools down, while the hot end continuously releases heat and heats up, creating a significant temperature difference (typically 40-70°C), achieving bidirectional cooling and heating functions. The semiconductor cooling plate of the semiconductor heat exchange mechanism 603 is located inside the two liquid storage tanks 601 on both sides. The cold end of the semiconductor cooling plate is paired with the liquid storage tank 601 containing cold water, while the hot end is paired with the liquid storage tank 601 containing hot water. This allows for more stable control of the liquid temperature inside the two liquid storage tanks 601. The semiconductor heat exchange mechanism 603 can also work in conjunction with the temperature sensing mechanism 602 located on the two liquid storage tanks 601 for regulation, making the cooling of the plastic part and the preheating of the mold cavity more stable and controllable.

[0044] The adapter 303 is connected to the conduit to the liquid storage tank 601, and the air pump 607 is also connected to the conduit. The air outlet of the air pump 607 is provided with the one-way valve 608. The one-way valve 608 can prevent liquid in the conduit from flowing into the air pump 607. At the same time, the upper sealing slide plate 605 is also provided at the liquid inlet of the conduit connecting the adapter 303 and the liquid storage tank 601. The upper sealing slide plate 605 is driven by the screw upper sealing mechanism 606. The screw upper sealing mechanism 606 has the same structural principle as the screw lowering mechanism 502.

[0045] The air pump 607, in conjunction with the one-way valve 608, the upper sealing slide plate 605, and the screw upper sealing mechanism 606, can blow out excess liquid inside the circulating inner channel 301. When the cavity plate 107 needs to be moved to a different station, the cavity plate 107 located at the cooling station and the preheating station needs to discharge excess liquid from the circulating inner channel 301 to prevent liquid leakage. When cleaning the residual liquid inside the circulating inner channel 301, the upper sealing slide plate 605 will move under the drive of the screw upper sealing mechanism 606 to seal the liquid storage ports of the liquid storage tanks 601 on both sides. Then, the air pump 607 is used to introduce gas into the circulating inner channel 301 to remove the residual liquid inside the circulating inner channel 301.

[0046] Furthermore, the flipping clamp 401 is rotatably mounted on the side of the work frame 103 near the stamping mechanism 102; the output shaft of the flipping motor 402 is connected to the flipping clamp 401, and the flipping motor 402 is fixedly mounted on one side of the work frame 103; the indexing component is connected to the processing frame 101 and is used to complete the station transfer after demolding the plastic part.

[0047] Furthermore, the indexing frame 701 is rotatably mounted on the processing frame 101; the output shaft of the indexing motor 702 is connected to the indexing frame 701, and the indexing motor 702 is mounted on the processing frame 101; the two pressing tables 703 are respectively slidably mounted on both sides of the indexing frame 701.

[0048] In this embodiment, during use, the arc groove of the work frame 103 that mates with the transition arc block 108 has a notch, which corresponds to the demolding station. The flipping clamp 401 is located at the notch and has a clamping groove for mates with the transition arc block 108. When the transition arc block 108 moves to the demolding station along with the cavity plate 107 and the turntable 105, the transition arc block 108 will mate with the flipping clamp 401. Then, the flipping clamp 401 will drive the cavity plate 107 of the demolding station to flip under the drive of the flipping motor 402, so that the plastic part of the cavity plate 107 can be ejected and demolded under the action of the ejector 201 and the corresponding mechanism. The demolded plastic part will fall into the pressing station slot provided on the pressing table 703. After demolding, the cavity plate 107 will be reset by the rotation of the flipping clamp 401 to facilitate the normal switching of the subsequent station.

[0049] Two pressing tables 703 are slidably disposed on both sides of the indexing frame 701. The indexing frame 701 is driven by the indexing motor 702. The pressing tables 703 can receive the plastic parts that fall off the mold. Then, the rotation of the indexing frame 701 drives the plastic parts to be transferred to the stamping station, and then the stamping mechanism 102 completes the stamping.

[0050] Preferably, the composite component provided by the present invention further includes a support frame 801, a lead screw lifting mechanism 802, and a pressure sensing plate 803.

[0051] Furthermore, the support frame 801 is slidably mounted on the processing frame 101; the lead screw lifting mechanism 802 is connected to the support frame 801 and is used to drive the support frame 801; the pressure sensing plate 803 is mounted on the top of the support frame 801.

[0052] In this embodiment, the support frame 801 is installed at the stamping station. The support frame 801 is driven by the lead screw lifting mechanism 802. The lead screw lifting mechanism 802 has the same structural principle as the lead screw lowering mechanism 502. The pressure sensing plate 803 is also installed on the top of the support frame 801. The pressure sensing plate 803 can sense and measure the pressure borne by the pressing table 703, so that the stamping pressure can be adjusted in real time.

[0053] After the pressing table 703 is moved to the stamping station by the rotation of the indexing frame 701, the support frame 801 will move upward under the action of the lead screw lifting mechanism 802. When the pressure sensing plate 803 at the top of the support frame 801 senses the weight value of the pressing table 703 and the internal plastic part, the pressing table 703 has been supported by the support frame 801. Then, the actual pressure of the stamping process can be measured by the pressure change of the pressure sensing plate 803, which is convenient for adjusting and calibrating the stamping mechanism 102.

[0054] Please see Figure 10 A method for injection molding and stamping composite forming of parts, using the aforementioned injection molding and stamping composite forming apparatus, includes the following steps. S1: The injection molding of the part is completed by the injection molding mechanism 104 in conjunction with the cavity plate 107 set on the turntable 105; S2: When the injection molding is completed, the main motor 106 will drive the turntable 105 to rotate. As the turntable 105 rotates, the cavity plate 107 located at the injection station will be transferred to the cooling station. S3: The cavity plate 107 located in the cooling station is cooled by the set temperature control component. After cooling, the main motor 106 drives the turntable 105 to rotate again. S4: The cooled cavity plate 107 is transferred to the demolding station by the rotation of the turntable 105 again, and the demolding of the plastic part is completed with the cooperation of the ejector component. S5: The plastic part that is detached from the cavity plate 107 will be transferred to the stamping station under the action of the conversion component. After the demolding is completed, the cavity plate 107 will rotate again with the turntable 105 and then be transferred to the preheating station. S6: The cavity plate 107 located in the preheating station will be preheated under the action of the temperature control component. When the turntable 105 rotates again, the cavity plate 107 in the preheating station will be transferred to the injection molding station for injection molding.
