Description

Technical Field

[0001] The present invention relates to the technical field of injection molded part production, and specifically to an in-mold longitudinal and transverse embedding device and an embedding method. Background Art

[0002] The longitudinal and transverse embedding device for plastic injection molded parts is a special device that precisely embeds inserts or connectors made of metal or other materials into an injection mold during the injection molding process. This device can position and fix the inserts in the injection mold, enabling the inserts to be integrally molded with the injection molded parts during the injection process.

[0003] Most of the existing longitudinal and transverse embedding devices for injection molded parts use a manipulator to directly clamp and insert the inserts into the injection mold. However, grooves are usually formed on the surface of the cylindrical metal inserts because the grooves on the surface of the metal inserts can not only increase the mechanical locking force between the inserts and the plastic, but also fix the cylindrical metal inserts in the injection mold through the surface grooves. In addition, the plastic injection molded parts integrally molded with the inserts can be effectively connected to the connecting device through the grooves on the surface of the inserts, ensuring that the plastic injection molded parts will not loosen or break during long-term use, thereby improving the durability and reliability of the connection.

[0004] However, because grooves are formed on the surface of the cylindrical inserts, it is difficult to ensure the accurate cooperation between the cylindrical inserts with grooves and the positioning grooves of the injection mold during the process of the manipulator clamping the cylindrical inserts. This will not only affect the normal injection molding of the injection molded parts, resulting in production stagnation, but also cause wear to the internal structure of the mold by the metal inserts, increasing the maintenance cost and replacement frequency of the mold. To address this, a corresponding placement rack often needs to be designed, enabling manual placement of the inserts accurately on the placement rack so that the manipulator can accurately match the inserts with the positioning grooves of the injection mold. Moreover, the design of the placement rack needs to consider factors such as the shape of the inserts and the position of the grooves, so that a specific placement rack needs to be designed for each type of insert. This will increase the design and manufacturing costs of the placement rack, and each time different inserts are replaced, the corresponding placement rack needs to be stopped and replaced to place the replaced inserts, thereby reducing the efficiency of the injection molded part production line. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, the present invention proposes an in-mold longitudinal and transverse embedding device and an embedding method. Through the cooperation of the sealing plate and the rotating plate, the rotating plate can drive the cylindrical insert clamped by the clamping piece to rotate, thereby adjusting the position of the cylindrical insert in the locking cylinder, so as to facilitate the adjustment of the position of the cylindrical insert and make it accurately cooperate with the positioning groove in the injection mold. There is no need to design corresponding placement racks for each type of insert, reducing the production volume of the placement racks, not only reducing the design cost and manufacturing cost of the placement racks, but also eliminating the need to stop the machine to replace the corresponding placement racks when replacing different inserts, thereby saving time and improving the production efficiency of the injection molding part production line, enhancing the practicality of the present invention.

[0015] An in-mold longitudinal and transverse embedding method, which is applicable to the above-mentioned in-mold longitudinal and transverse embedding equipment, and the steps of the method are as follows:

[0016] S1: The conveyor belt conveys the storage rack with cylindrical grooves to the injection molding machine, inserts the cylindrical insert into the cylindrical groove of the storage rack, so that the conveyor belt conveys the storage rack storing the cylindrical insert to one side of the injection molding machine. At this time, the three-axis movement platform drives the rack to move longitudinally and transversely until the rack is located above the storage rack; control the steering motor of the three-axis movement platform to drive the rack to rotate so that the locking cylinder is aligned with the cylindrical insert;

[0017] S2: Control the three-axis movement platform to drive the rack to descend, insert the cylindrical insert into the locking cylinder, control the air pump to operate through the controller, so that the gas conveyed by the air pump drives the rotating plate to drive the cylindrical insert to rotate, and the gas conveyed by the air pump flows through the voltage stabilizing tank and is sprayed on the surface of the cylindrical insert through the air holes;

[0018] S3: During the operation of the air pump, control the infrared rangefinder to operate, so that the infrared rangefinder detects the position of the groove formed on the surface of the cylindrical insert. After detecting the groove formed on the surface of the cylindrical insert, the infrared rangefinder transmits an electrical signal to the controller, and the controller controls the air pump to stop to complete the position correction of the cylindrical insert;

[0019] S4: Control the three-axis movement platform to drive the cylindrical insert clamped by the locking cylinder between the upper mold and the lower mold of the injection mold, control the three-axis movement platform to drive the rack to align the cylindrical insert with the positioning groove of the injection mold and complete the embedding of the cylindrical insert, and then control the injection mold to close and then carry out injection molding;

At the same time, during the taking out process, control the air pump to cool the injection molded part.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. Through the cooperation of the sealing plate and the rotating plate, the rotating plate of the present invention can drive the cylindrical insert clamped by the clamping piece to rotate, thereby adjusting the position of the cylindrical insert in the locking cylinder, facilitating the adjustment of the position of the cylindrical insert, enabling it to be accurately matched with the positioning groove in the injection mold. There is no need to design corresponding placement racks for each type of insert, reducing the production volume of the placement racks. This not only reduces the design cost and manufacturing cost of the placement racks, but also eliminates the need to stop the machine to replace the corresponding placement racks when changing different inserts, thus saving time and improving the production efficiency of the injection molding part production line, enhancing the practicality of the present invention.

[0023] 2. The present invention drives the rotating ring and the rotating plate to rotate in opposite directions through the gear rod. For the cylindrical insert clamped by the clamping piece, the rotating speed of the rotating ring rotating in the opposite direction is increased, so that the air holes on the surface of the rotating plate can clean the surface of the cylindrical insert multiple times within the same time, improving the cleaning effect. Moreover, when removing the injection molding part, if the gas ejected through the air holes blows towards the surface of the injection molding part, it can not only accelerate the cooling process of the injection molding part, shorten the cooling time, and improve the production efficiency, but also the rapid cooling helps to stabilize the size and shape of the injection molding part, reduce deformation and shrinkage problems, and greatly improve the quality of the injection molding part. Furthermore, the practicality of the present invention is further enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0035] As Figures 1 to 8 shown, an in-mold longitudinal and transverse embedding device according to the present invention includes:

[0036] Frame 1, one side of the frame 1 is fixedly installed with a connecting rod 11; a ventilation port 111 is opened inside the connecting rod 11; one end of the connecting rod 11 away from the frame 1 is fixedly installed with a locking cylinder 12; the bottom of the locking cylinder 12 is rotatably connected with a clip 121 through a torsion spring; a pushing ring 122 is arranged between the clip 121 and the barrel wall of the locking cylinder 12; the pushing ring 122 is connected with the bottom of the locking cylinder 12 through an airbag 123; one end of the airbag 123 away from the locking cylinder 12 is communicated with the ventilation port 111 of the connecting rod 11;

[0037] Rotating plate 131, a circular groove 13 communicated with the airbag 123 is opened at the bottom of the barrel of the locking cylinder 12; the rotating plate 131 is rotatably connected in the circular groove 13; grooves 132 are opened on the surface of the rotating plate 131; a sealing plate 133 is slidably and sealingly connected in the grooves 132; the sealing plate 133 is connected with the bottom of the grooves 132 through a sealing spring 134; a voltage stabilizing groove 14 communicated with the circular groove 13 is opened on the side wall of the locking cylinder 12; a voltage stabilizing plate 141 is slidably and sealingly connected in the voltage stabilizing groove 14; the voltage stabilizing plate 141 is connected with the bottom of the voltage stabilizing groove 14 through a reset spring 142.

[0038] An infrared rangefinder 15 is inlaid on the barrel wall of the locking cylinder 12; a clamping block 124 is fixedly installed on one side of the clip 121 away from the locking cylinder 12.

[0039] Ball bearings 125 are inlaid on the inner ring wall of the pushing ring 122;

[0040] The existing cylindrical inserts have grooves on their surfaces. This makes it difficult to ensure the accurate cooperation between the grooved cylindrical inserts and the positioning grooves of the injection mold during the process of the manipulator gripping the cylindrical inserts. It will not only affect the normal injection molding of the injection molded parts, resulting in production stagnation, but also cause wear to the internal structure of the mold by the metal inserts, increasing the maintenance cost and replacement frequency of the mold. In this regard, it is often necessary to design corresponding placement racks so that workers can accurately place the inserts on the placement racks, so that the manipulator can accurately cooperate the inserts with the positioning grooves of the injection mold. Moreover, the design of the placement rack needs to consider factors such as the shape of the insert and the position of the groove, so that a specific placement rack needs to be designed for each type of insert. This will increase the design and manufacturing costs of the placement rack. Moreover, every time different inserts are replaced, it is necessary to stop the machine to replace the corresponding placement rack to place the replaced inserts, which will lead to a decrease in the efficiency of the injection molded part production line;

[0041] When the present invention is in use, the longitudinal and transverse embedding device is installed on the injection molding production line through a three-axis motion platform, that is, the three-axis motion platform drives the longitudinal and transverse embedding device to move longitudinally and transversely;

[0042] In the initial state, the user inserts the cylindrical insert into the storage rack with a cylindrical groove, and then the conveyor belt transports the storage rack to the longitudinal and transverse embedding device. For cylindrical inserts with different grooves on the surface, a common storage rack with a cylindrical groove can be used for storage and placement;

[0043] Since the air vent 111 of the connecting rod 11 is communicated with an external air pipe, the clamping piece 121 is rotationally connected to the bottom of the locking cylinder 12 through a torsion spring. When the three-axis motion platform is controlled to drive the frame 1 to the storage rack, so that the cylindrical insert in the storage rack can be inserted into the locking cylinder 12, and then the controller is used to control the external air pump to transport air into the air vent 111, so that the air entering the air vent 111 can enter the airbag 123. While the airbag 123 is inflated and extended, the airbag 123 can push the pushing ring 122 to move away from the connecting rod 11, so that the pushing ring 122 can push the three clamping pieces 121 to rotate towards each other through the inner ring wall, so that the three clamping pieces 121 can clamp the cylindrical insert inserted into the locking cylinder 12;

[0044] At this time, only a part of the cylindrical insert is located inside the locking cylinder 12, while most parts of the cylindrical insert need to be exposed outside the locking cylinder 12 so that the three-axis motion platform can drive the exposed part of the cylindrical insert through the frame 1 to insert into the injection mold, enabling the cylindrical insert to be stably connected in the positioning groove of the injection mold; when the pushing ring 122 pushes the clamping piece 121 to clamp the cylindrical insert, the air pump continues to deliver air into the air vent 111, increasing the air pressure inside the airbag 123. Since the rotating plate 131 is eccentrically installed in the circular groove 13, the contact points of the sealing plate 133 with the inner wall of the circular groove 13 change continuously during rotation, thus forming multiple air chambers of different sizes, and the volume of the air chamber gradually increases as it moves away from the connection of the airbag 123;

[0045] Moreover, the gas is filled between the two sealing plates 133, generating a pressure difference on both sides of the sealing plate 133, so that the sealing plate 133 rotates in the circular groove 13 under the push of the pressure difference; as the sealing plate 133 rotates away from the airbag 123, the sealing plate 133 is always in contact with the groove wall of the circular groove 13 under the push of the restoring force of the sealing spring 134; when the sealing plate 133 rotates to the side close to the pressure stabilizing groove 14, the volume of the air chamber gradually decreases, and the air is compressed and discharged into the pressure stabilizing groove 14;

[0046] As the air pressure in the pressure stabilizing groove 14 continuously increases, until the air pressure in the pressure stabilizing groove 14 is greater than the elastic force of the return spring 142, the air pressure pushes the pressure stabilizing plate 141 to squeeze the return spring 142 and extend out of the pressure stabilizing groove 14. At this time, the pressure stabilizing plate 141 drives the L-shaped hole on its surface to extend out of the pressure stabilizing groove 14, thereby discharging the gas in the pressure stabilizing groove 14; during the rotation of the rotating plate 131, the rotating plate 131 can drive the clamping piece 121 to rotate, so that the clamping piece 121 drives the clamped cylindrical insert to rotate, enabling the rotating cylindrical insert to drive the groove on its surface to rotate synchronously. When the cylindrical insert drives the groove on its surface to rotate to the infrared distance measuring instrument 15, the infrared rays emitted by the infrared distance measuring instrument 15 irradiate into the groove on the surface of the cylindrical insert. When the measured distance is detected to be the set distance, the infrared distance measuring instrument 15 transmits an electrical signal to the controller, and the controller is used to control the air pump to stop working, so that the air pump no longer delivers gas into the circular groove 13, and the sealing plate 133 in the circular groove 13 is no longer pushed by the gas. At this time, the rotating plate 131 stops rotating, enabling the cylindrical insert clamped by the clamping piece 121 to complete the position adjustment inside the locking cylinder 12;

[0047] Through the cooperation of the sealing plate 133 and the rotating plate 131, the rotating plate 131 can drive the cylindrical insert clamped by the clamping piece 121 to rotate, so as to adjust the position of the cylindrical insert in the locking cylinder 12, facilitating the adjustment of the position of the cylindrical insert to accurately cooperate with the positioning groove in the injection mold. There is no need to design corresponding placement racks for each type of insert, reducing the production volume of the placement racks. This not only reduces the design cost and manufacturing cost of the placement racks, but also eliminates the need to stop the machine to replace the corresponding placement racks when changing different inserts, thus saving time and improving the production efficiency of the injection molding part production line, enhancing the practicality of the present invention;

[0048] Moreover, by providing the clamping block 124, and the clamping block 124 is made of fluororubber material, when the clamping piece 121 clamps the cylindrical insert through the clamping block 124, the clamping block 124 can undergo elastic deformation under the extrusion of the clamping piece 121 and the cylindrical insert, thereby increasing the contact area between the clamping block 124 and the cylindrical insert. And by arranging three parallel clamping blocks 124 on one clamping piece 121, the three parallel clamping blocks 124 can increase the friction coefficient between the clamping piece 121 and the cylindrical insert, thus improving the clamping effect of the clamping piece 121 on the cylindrical insert;

[0049] Moreover, after injection molding, the surface temperature of the cylindrical insert is relatively high, and the fluororubber material has the characteristic of high temperature resistance, so that the fluororubber clamping block 124 can effectively clamp the injection molded part without melting, thus ensuring the actual application effect of the present invention. When the pushing ring 122 is in sliding contact with the clamping piece 121, there will be frictional loss between the pushing ring 122 and the clamping piece 121. To ensure that the pushing ring 122 can push the clamping piece 121 to stably clamp the cylindrical insert, the present invention embeds balls 125 on the inner ring wall of the pushing ring 122, so that the pushing ring 122 changes from sliding contact with the clamping piece 121 through the balls 125 to rolling contact, reducing the friction force between the pushing ring 122 and the clamping piece 121, thereby reducing the wear between the pushing ring 122 and the clamping piece 121 and improving the service life and use effect of the pushing ring 122 and the clamping piece 121.

[0050] As an implementation manner of the present invention, a rotating ring 161 is installed at one end of the locking cylinder 12 away from the connecting rod 11; an annular groove 16 communicating with the pressure stabilizing groove 14 is provided on the inner wall of the locking cylinder 12; the rotating ring 161 is rotationally and sealingly connected in the annular groove 16; and a gas hole 162 communicating with the annular groove 16 is opened at one end of the rotating ring 161 away from the locking cylinder 12.

[0051] The inside of the locking cylinder 12 is provided with a cavity 17; a gear rod 171 is rotatably connected inside the cavity 17; teeth 172 meshing with the gear rod 171 are fixedly connected to the surface of the rotating ring 161; a transmission gear 173 fixedly connected to the rotating plate 131 is rotatably connected inside the locking cylinder 12; the gear rod 171 and the transmission gear 173 are meshed through a connecting gear 174.

[0052] The inner wall of the air vent 111 is provided with a slot 112; a plug rod 113 is slidably connected inside the slot 112; the plug rod 113 and the bottom of the slot 112 are fixedly connected through a support spring 114; a card slot 115 matching with the slot 112 is provided on the surface of the locking cylinder 12.

[0053] The outer wall of the connecting rod 11 is provided with a pressing groove 18 communicating with the slot 112; a pressing plate 181 is slidably and sealingly connected inside the pressing groove 18;

[0054] When the air pump continuously conveys gas into the pressure stabilizing tank 14 and pushes the pressure stabilizing plate 141 to open, so that the gas in the pressure stabilizing tank 14 can enter the annular groove 16 communicated therewith, so that the gas entering the annular groove 16 can be ejected through the air holes 162 on the surface of the rotating ring 161, so that the gas ejected from the air holes 162 can blow towards the surface of the cylindrical insert exposed from the locking cylinder 12, so that the dust on the surface of the cylindrical insert can be separated from the cylindrical insert under the blowing of the gas, thereby improving the cleanliness of the surface of the cylindrical insert. When the clean cylindrical insert is inserted into the positioning groove of the injection mold, the cylindrical insert will not affect the connection strength between the cylindrical insert and the injection molded part due to the dust on the surface; furthermore, the injection quality of the injection molded part is improved;

[0055] Moreover, through the arrangement of the transmission gear 173 and the connecting gear 174, the rotating plate 131 can drive the transmission gear 173 to rotate, so that the transmission gear 173 can drive the gear rod 171 to rotate in the same direction as the transmission gear 173 through the connecting gear 174. Since both ends of the gear rod 171 are gear ends, the gear rod 171 can drive the rotating ring 161 to rotate through the teeth 172 meshing therewith, so that the rotating ring 161 rotates in the opposite direction to the rotating plate 131, so that within a relatively small circumferential rotation range of the cylindrical insert, the air holes 162 on the surface of the rotating plate 131 can also effectively clean the surface of the cylindrical insert, and the rotating ring 161 rotating in the opposite direction rotates faster relative to the cylindrical insert clamped by the clamping piece 121, so that the air holes 162 on the surface of the rotating plate 131 clean the surface of the cylindrical insert multiple times within the same time, improving the cleaning effect;

[0056] Moreover, when taking out the injection molded part, if the gas ejected through the air holes 162 blows towards the surface of the injection molded part, it can not only accelerate the cooling process of the injection molded part, shorten the cooling time, and improve production efficiency; at the same time, rapid cooling also helps to stabilize the size and shape of the injection molded part, reduce deformation and shrinkage problems, and greatly improve the quality of the injection molded part; thereby further enhancing the practicality of the present invention;

[0057] Since the existing locking cylinder 12 is mostly connected to the connecting rod 11 by a threaded connection; and to prevent gas leakage, it is often necessary to tightly thread-connect the locking cylinder 12 and the connecting rod 11, which makes it difficult to disassemble the locking cylinder 12, thus affecting the disassembly and replacement efficiency of the locking cylinder 12, and the downtime for disassembly is relatively long, which will affect the production efficiency of the entire injection molding production line;

[0058] In response, the present invention, through the cooperation of the pressing plate 181 and the insertion rod 113, when it is necessary to disassemble the locking cylinder 12, the user only needs to pinch the pressing plates 181 on both sides of the connecting rod 11. Since the pressing groove 18 is filled with hydraulic oil and the pressing plate 181 is slidably and sealingly connected in the pressing groove 18, when the pressing plate 181 is squeezed into the pressing groove 18, the hydraulic oil in the pressing groove 18 will enter the insertion slot 112, so that the insertion rod 113 in the insertion slot 112 is pushed by the hydraulic oil and squeezes the support spring 114 into the insertion slot 112;

[0059] At this time, the insertion rod 113 extends out of the card slot 115, so that the locking cylinder 12 is separated from the connecting rod 11. The user then pulls out the old locking cylinder 12 at this time and inserts the new locking cylinder 12 into the air vent 111 of the connecting rod 11. Subsequently, the pressing plate 181 is released, so that the insertion rod 113 extends out of the insertion slot 112 under the pushing force of the restoring force of the support spring 114 and slidably contacts one end of the locking cylinder 12 inserted into the air vent 111. By pushing the locking cylinder 12, the locking cylinder 12 slides in the air vent 111 until the card slot 115 cooperates with the insertion slot 112. At this time, the insertion rod 113 enters the card slot 115 and seals and fixes the locking cylinder 12 in the air vent 111. Thus, there is no need to use a threaded connection to connect the locking cylinder 12 and the connecting rod 11, reducing the disassembly difficulty of the locking cylinder 12, and then facilitating the user to quickly disassemble the locking cylinder 12, reducing the downtime for disassembly, improving the production efficiency of the entire injection molding production line, and enhancing the practicality of the present invention.

[0060] An in-mold longitudinal and transverse embedding method, which is applicable to the above-mentioned in-mold longitudinal and transverse embedding equipment. The steps of this method are as follows:

[0061] S1: The conveyor belt transports the storage rack with cylindrical grooves to the injection molding machine. Insert the cylindrical insert into the cylindrical groove of the storage rack, so that the conveyor belt transports the storage rack storing the cylindrical insert to one side of the injection molding machine. At this time, the three-axis motion platform drives the frame 1 to move longitudinally and horizontally until the frame 1 is located above the storage rack. Control the steering motor of the three-axis motion platform to drive the frame 1 to rotate so that the locking cylinder 12 is aligned with the cylindrical insert.

[0062] S2: Control the three-axis motion platform to drive the frame 1 to descend, so that the cylindrical insert is inserted into the locking cylinder 12. Control the air pump to operate through the controller. When the gas transported by the air pump drives the rotating plate 131 to drive the cylindrical insert to rotate, the gas transported by the air pump flows through the pressure stabilizing groove 14 and is sprayed on the surface of the cylindrical insert through the air hole 162.

[0063] S3: During the operation of the air pump, control the infrared distance measuring instrument 15 to operate, so that the infrared distance measuring instrument 15 detects the position of the groove opened on the surface of the cylindrical insert. After detecting the groove opened on the surface of the cylindrical insert, the infrared distance measuring instrument 15 transmits an electrical signal to the controller, and the controller controls the air pump to stop, completing the position correction of the cylindrical insert.

[0064] S4: Control the three-axis motion platform to drive the cylindrical insert clamped by the locking cylinder 12 between the upper mold and the lower mold of the injection mold. Control the three-axis motion platform to drive the frame 1 to align the cylindrical insert with the positioning groove of the injection mold and complete the embedding of the cylindrical insert. Subsequently, control the injection mold to close and then perform injection molding.

[0065] S5: After injection molding, control the cooling system to cool and solidify the injection molded part in the injection mold. Then control the upper mold and the lower mold to open. Control the three-axis motion platform to drive the locking cylinder 12 to take out the injection molded part and place it on the storage rack. At the same time, during the taking out process, control the air pump to cool the injection molded part.

An in-mold longitudinal and transverse embedding method, which is applicable to the in-mold longitudinal and transverse embedding device described in any one of claims 1-7, and is characterized in that: The steps of the method are as follows: S1: The conveyor belt conveys the storage rack with a cylindrical groove to the injection molding machine, inserts the cylindrical insert into the cylindrical groove of the storage rack, so that the conveyor belt conveys the storage rack storing the cylindrical insert to one side of the injection molding machine. At this time, the three-axis motion platform drives the frame (1) to move longitudinally and horizontally until the frame (1) is located above the storage rack; the steering motor of the three-axis motion platform is controlled to drive the frame (1) to rotate so that the locking cylinder (12) is aligned with the cylindrical insert. S2: The three-axis motion platform is controlled to drive the frame (1) to descend so that the cylindrical insert is inserted into the locking cylinder (12). The air pump is controlled to operate through the controller. When the gas conveyed by the air pump drives the rotating plate (131) to drive the cylindrical insert to rotate, the gas conveyed by the air pump flows through the pressure stabilizing groove (14) and is sprayed on the surface of the cylindrical insert through the air holes (162). S3: During the operation of the air pump, the infrared distance measuring instrument (15) is controlled to operate so that the infrared distance measuring instrument (15) detects the position of the groove opened on the surface of the cylindrical insert. After detecting the groove opened on the surface of the cylindrical insert, the infrared distance measuring instrument (15) transmits an electrical signal to the controller, and the controller controls the air pump to stop, completing the position correction of the cylindrical insert. S4: The three-axis motion platform is controlled to drive the cylindrical insert clamped by the locking cylinder (12) between the upper mold and the lower mold of the injection mold. The three-axis motion platform is controlled to drive the frame (1) to align the cylindrical insert with the positioning groove of the injection mold and complete the embedding of the cylindrical insert. Then, the injection mold is controlled to close the mold, and then injection molding is carried out. S5: After injection molding, the cooling system is controlled to cool and solidify the injection molded part in the injection mold. Then, the upper mold and the lower mold are controlled to open. The injection molded part is taken out and placed on the storage rack by controlling the three-axis motion platform to drive the locking cylinder (12). At the same time, during the taking out process, the air pump is controlled to cool the injection molded part.
