Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glue filling, in particular to a table plate type liquid injection machine. BACKGROUND

[0002] In the prior art, when resin glue is attached to the surface of a product for protection, the resin glue is usually filled into the mold cavity of a liquid injection mold with a liquid injection port, and then the product is placed at the liquid injection port of the liquid injection mold so that the lower surface of the product is in full contact with the filled resin glue. After the filled resin glue solidifies, the product together with the solidified resin glue can be removed from the liquid injection mold. Thus, the resin glue is attached to the surface of the product for protection.

[0003] The usual operation is that the resin glue is manually filled into the mold cavity of the corresponding liquid injection mold with a liquid injection port, and the product is directly and naturally placed at the liquid injection port of the liquid injection mold to cover the resin glue filled in the mold cavity of the corresponding liquid injection mold.

[0004] For the above-mentioned related practices, the present inventors found that they have certain defects and shortcomings in the work process.

[0005] Specifically, on the one hand, manually filling resin glue into the mold cavity of the corresponding liquid injection mold with a liquid injection port is very troublesome and laborious, and the filling amount of resin glue is not easy to control, and the filling efficiency cannot be effectively improved. On the other hand, directly and naturally placing the product at the liquid injection port of the liquid injection mold to cover the resin glue filled in the mold cavity of the corresponding liquid injection mold, the placed product is easy to shake, shift or even slip due to external factors such as wind blowing and accidental touching, so that the position of the resin glue attached to the surface of the product changes, resulting in poor operation reliability and some processing defective products.

[0006] In view of this, the present inventors, combining with work experience, through in-depth thinking of the problems encountered in work, referring to a large number of scientific research data and literature, and through retrieval novelty search, gradually conceived and designed the present application to solve the related technical problems.

[0073] The table plate type liquid injection machine 1000 according to the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0074] Referring to Figures 1 to 10 As shown, the table plate type liquid injection machine 1000 according to the embodiment of the present application comprises a table plate 10, a liquid injection mold 20, a left-right moving mechanism 30 for controlling left-right movement of the liquid injection mold 20, a liquid injection member 40, a pressure head member 50, and a lifting mechanism 60 for controlling up-down movement of the pressure head member 50.

[0075] The left-right moving mechanism 30 is fixedly arranged on the front part of the upper end surface of the table plate 10 in the left-right direction. The liquid injection mold 20 is fixedly arranged on the left-right moving mechanism 30, and a mold cavity is formed in the liquid injection mold 20. The liquid injection mold 20 is provided with a liquid injection port 201 penetrating through the upper part thereof to the mold cavity. The liquid injection member 40 and the lifting mechanism 60 are fixedly arranged on the rear part of the upper end surface of the table plate 10 from left to right. The pressure head member 50 is fixedly arranged on the lifting mechanism 60.

[0076] When the left-right moving mechanism 30 controls the liquid injection mold 20 to move to the left to the first position, the liquid injection port 201 is located directly below the liquid injection member 40 to receive the glue liquid flowing downward from the liquid injection member 40.

[0077] When the left-right moving mechanism 30 controls the liquid injection mold 20 to move to the right to the second position, the liquid injection port 201 is located directly below the pressure head member 50, so that the liquid injection port 201 is covered by the pressure head member 50 when the lifting mechanism 60 controls the pressure head member 50 to descend by a preset stroke.

[0078] Based on the above description, it can be clear that the table plate type liquid injection machine 1000 according to the present application is mainly used to coat a layer of resin glue liquid on the surface of a product 2000 to protect the product 2000 in specific implementation.

[0079] Specifically, in the application, the liquid injection mold 20 is controlled to move left to the first position by the left-right moving mechanism 30, so that the liquid injection port 201 is located directly below the liquid injection member 40 to receive the glue liquid flowing downward from the liquid injection member 40. After the mold cavity is filled with a suitable amount of resin glue liquid, the liquid injection mold 20 is controlled to move right to the second position by the left-right moving mechanism 30, so that the liquid injection port 201 is located directly below the pressure head member 50. In this way, the product 2000 is placed on the liquid injection port 201, and the product 2000 is pressed downward by the pressure head member 50 to seal the liquid injection port 201. At this time, the suitable amount of resin glue liquid filled in the mold cavity is attached to the surface of the pressed product 2000. After the resin glue liquid attached to the surface of the product 2000 is solidified and shaped, the pressure head member 50 is controlled to rise by the lifting mechanism 60, and the product 2000 with the resin glue liquid attached to the surface is taken out.

[0080] Obviously, the application has the following technical effects:

[0081] On the one hand, the application is provided with the liquid injection member 40. When the resin glue liquid used is used up, the liquid injection mold 20 is controlled to move left to the first position by the left-right moving mechanism 30, so that the liquid injection port 201 is located directly below the liquid injection member 40 to receive a suitable amount of glue liquid flowing downward from the liquid injection member 40. The mold cavity is filled with a suitable amount of resin glue liquid, which eliminates the trouble of manually filling the mold cavity with resin glue liquid, thereby saving labor.

[0082] On the other hand, the pressure head member 50 provided in the application can play a role in pressing and fixing. The product 2000 is pressed downward by the pressure head member 50 to seal the liquid injection port 201. At this time, the suitable amount of resin glue liquid filled in the mold cavity is stably attached to the surface of the product 2000. After the product 2000 is pressed and fixed, it is not easy to move, so that the resin glue liquid can better connect with the position on the surface of the product 2000 that needs to be attached to form an integral body during the curing process, thereby increasing the yield of the finished product and making the application reliable.

[0083] Furthermore, the above-mentioned optimization design makes the whole application have strong practicability and good use effect.

[0084] Further, in specific implementation, as shown in Figure 2 and Figure 3 According to one embodiment of the application, the application further comprises a front-back moving mechanism 70 for controlling the front-back movement of the liquid injection mold 20.

[0085] The front-back moving mechanism 70 is fixedly arranged on the front end surface of the table plate 10 in the front-back direction, and the left-right moving mechanism 30 is fixedly arranged on the front-back moving mechanism 70 in the left-right direction.

[0086] Therefore, when the present application is used, the liquid injection mold 20 can be moved between the first position and the second position under the control of the left-right moving mechanism 30 by controlling the rear movement of the liquid injection mold 20 and the left-right moving mechanism 30 by the front-back moving mechanism 70 by a preset stroke. When the liquid injection mold 20 is at the second position and the product 2000 with resin glue on the surface needs to be taken, the liquid injection mold 20 and the left-right moving mechanism 30 can be moved forward by a preset stroke by the front-back moving mechanism 70, so that the liquid injection mold 20 can be moved to the right front end of the table plate 10, and the operator can take the product 2000 conveniently.

[0087] Preferably, in the technical solution, according to an embodiment of the present application, referring to Figure 4 、 Figure 5 and Figure 6 , the liquid injection member 40 comprises a fixed plate 401, a glue injection barrel 402 for storing glue, and a glue injection needle 403 for discharging glue.

[0088] The glue injection barrel 402 is fixedly arranged on the front end surface of the fixed plate 401, and the top of the glue injection barrel 402 is provided with a glue inlet 4021, and the bottom of the glue injection barrel 402 is connected with the glue injection needle 403 downward.

[0089] When the liquid injection mold 20 is controlled by the left-right moving mechanism 30 to move to the left to the first position, the liquid injection port 201 is located directly below the glue injection needle 403 to receive the glue flowing downward from the glue injection needle 403.

[0090] Therefore, it can be clearly seen that the resin glue in the glue injection barrel 402 can flow out through the glue injection needle 403 and drip downward through the liquid injection port 201 into the mold cavity of the liquid injection mold 20 at the first position.

[0091] Furthermore, in the specific implementation, referring to Figure 4 、 Figure 5 and Figure 6 , according to an embodiment of the present application, the liquid injection member 40 further comprises an up-down moving mechanism 404 for controlling the up-down movement of the glue injection barrel 402 and the glue injection needle 403 connected therewith.

[0092] The upper and lower moving mechanism 404 is fixed on the front end surface of the fixed plate 401; the glue injection barrel 402 and the glue injection needle 403 connected therewith are fixed on the upper and lower moving mechanism 404;

[0093] When the left and right moving mechanism 30 controls the liquid injection mold 20 to move left to the first position, the upper and lower moving mechanism 404 can control the glue injection barrel 402 and the glue injection needle 403 connected therewith to move downward by a preset stroke so that the lower end of the glue injection needle 403 extends into the liquid injection port 201.

[0094] Therefore, through the optimization design of the above structure, when the left and right moving mechanism 30 controls the liquid injection mold 20 to move left to the first position, the glue injection barrel 402 and the glue injection needle 403 connected therewith can be controlled by the upper and lower moving mechanism 404 to move downward by a preset stroke so that the lower end of the glue injection needle 403 extends into the liquid injection port 201, so that the resin glue liquid can be dropped into the mold cavity of the liquid injection mold 20 at the first position, and the resin glue liquid is not easy to splash out of the mold cavity of the liquid injection mold 20, so that the application can be used more reliably.

[0095] After the above glue injection action is completed, the glue injection barrel 402 and the glue injection needle 403 connected therewith can be controlled by the upper and lower moving mechanism 404 to move upward by a preset stroke so that the lower end of the glue injection needle 403 is away from the liquid injection port 201, and then the liquid injection mold 20 can be controlled by the left and right moving mechanism 30 to move right to the second position to perform the next step of the related process of attaching the resin glue liquid to the surface of the product 2000.

[0096] Further, through the above optimization design, the use effect of the whole application can be effectively improved.

[0097] In addition, in the technical solution, it is also shown in Figure 4 、 Figure 5 and Figure 6 According to one embodiment of the application, the liquid injection member 40 further comprises a rotating shaft 405 and a locking nut 406.

[0098] The fixed plate 401 has an axial hole 4011 penetrating the front and rear end surfaces in the lower part and an arc-shaped slot 4012 with the center point of the axial hole 4011 as the center in the upper part;

[0099] Based on this, in the present application, the up-down moving mechanism 404 has a rotating plate 4041 which is attached to the front end surface of the fixed plate 401; the lower end of the rotating plate 4041 is rotatably connected to the lower part of the fixed plate 401 through the rotating shaft member 405 which is arranged in the front-rear direction and penetrates the shaft hole 4011; the rear end surface of the rotating plate 4041 has a lock hole 40411 which is opposite to the arc-shaped slot 4012; the lock nut 406 is fixed to the rear end surface of the fixed plate 401 and is screwed into the lock hole 40411 through the arc-shaped slot 4012.

[0100] When the lock nut 406 is loosened, the rotating plate 4041 can rotate around the rotating shaft member 405 so that the lower end of the glue injection needle 403 can be adjusted in angle.

[0101] It should be noted here that for different liquid injection molds 20, they can have special shapes and the upper liquid injection port 201 can not be arranged vertically upward, that is, it can be arranged obliquely so as to face the upper left or upper right. At this time, the lock nut 406 can be loosened and the rotating plate 4041 can be rotated around the rotating shaft member 405 so that the lower end of the glue injection needle 403 can be adjusted in angle to the same direction as the opening direction of the upper liquid injection port 201 of the liquid injection mold 20 with a special shape. Then, the lock nut 406 is tightened again. In this way, the liquid injection member 40 of the present application is more flexible to use and can be used to fill resin glue into the mold cavity of the liquid injection mold 20 with a special shape whose upper liquid injection port 201 opens in different directions.

[0102] In specific operation, after the angle of the lower end of the glue injection needle 403 is adjusted, the left-right moving mechanism 30 controls the liquid injection mold 20 to move to the left to the first position, and then the up-down moving mechanism 404 controls the glue injection barrel 402 and the glue injection needle 403 connected thereto to move downward by a preset stroke so that the lower end of the glue injection needle 403 extends into the liquid injection port 201. In this way, resin glue can be dropped into the mold cavity of the liquid injection mold 20 at the first position at a close distance, so that the resin glue is also not easy to splash out of the mold cavity of the liquid injection mold 20, so that the present application is still reliable to use.

[0103] After the above glue filling action is completed, the glue injection barrel 402 and the glue injection needle 403 connected thereto can be controlled by the up-down moving mechanism 404 to move upward by a preset stroke so that the lower end of the glue injection needle 403 is away from the liquid injection port 201. Then, the liquid injection mold 20 can be controlled by the left-right moving mechanism 30 to move to the right to the second position for the next process of attaching resin glue to the surface of the product 2000.

[0104] Further, the liquid injection component 40 has high flexibility and adaptability, and the overall use effect is further improved.

[0105] Further, in specific implementation, according to one embodiment of the present application, as shown in Figure 4 、 Figure 5 and Figure 6 , an angle scale line 4013 is arranged on the upper part of the front end surface of the fixing plate 401 to indicate the angle of the lower end of the glue injection needle 403, and the angle scale line 4013 is provided with angle values.

[0106] The upper part of the rotating plate 4041 is provided with an indicating arrow 40412 pointing to the angle scale line 4013, and the central axis of the indicating arrow 40412 is parallel to the central axis of the glue injection needle 403 in the front-rear direction.

[0107] Therefore, for the liquid injection mold 20 with different opening directions and special-shaped structures, the glue injection needle 403 can be adjusted to match the glue injection into the mold cavity of the liquid injection mold 20 with a special-shaped structure. When adjusting the direction of the glue injection needle 403, the angle of the glue injection needle 403 can be accurately measured by the angle scale line 4013, the angle values and the indicating arrow 40412, which can be recorded and archived for subsequent glue injection into the mold cavity of the liquid injection mold 20 with the same special-shaped structure, so as to provide data reference and reduce the labor intensity when adjusting the direction of the glue injection needle 403 again, thereby making the use of the present application more convenient and labor-saving.

[0108] Further, in the technical solution, according to one embodiment of the present application, as shown in Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , the pressure head component 50 includes an upper connecting plate 501, a plurality of guide rods 502, a lower connecting plate 503, a plurality of buffer springs A 504 and a vacuum suction head 505 for adsorbing products 2000.

[0109] The upper connecting plate 501 is fixed on the lifting mechanism, and a plurality of guide holes 5011 are uniformly arranged on the periphery of the upper connecting plate 501 and penetrate the upper and lower end faces; the upper ends of the plurality of guide rods 502 are respectively outwardly provided with a ring of supporting outer edges 5021, and the plurality of guide rods 502 are correspondingly movably arranged in the plurality of guide holes 5011 from top to bottom, and the lower ends are connected to the upper end face periphery of the lower connecting plate 503, and the lower bottom surfaces of the supporting outer edges 5021 are all abutted to the upper end face of the upper connecting plate 501; the plurality of slow compression springs A504 are all in a natural state or a compressed state and are sleeved on the plurality of guide rods 502 and are limited between the lower bottom surface of the upper connecting plate 501 and the upper end face of the lower connecting plate 503; the vacuum suction head 505 is fixed downward on the lower bottom surface of the lower connecting plate 503.

[0110] Therefore, by optimizing the structure of the pressure head member 50, the application has the following technical effects:

[0111] On the one hand, the application is provided with a vacuum suction head 505 for adsorbing the product 2000, so that in the specific use of the application, the product 2000 is first adsorbed and fixed on the bottom of the vacuum suction head 505 in a suitable direction and angle, and then when the liquid injection mold 20 filled with a suitable amount of resin glue is controlled by the left-right moving mechanism 30 to move to the right to the second position, the pressure head member 50 is controlled to descend by a predetermined stroke by the lifting mechanism 60, and the product 2000 is pressed down by the vacuum suction head 505 of the pressure head member 50 to cover the liquid injection port 201, at this time, the suitable amount of resin glue filled in the mold cavity can be attached to the surface of the pressed product 2000, this process can save the manual process of placing the product 2000 on the liquid injection port 201, so that the application is more convenient and safe and reliable to operate, and the hand is not easy to be pressed by the downward moving pressure head member 50.

[0112] On the other hand, the application is provided with a plurality of guide rods 502 and a plurality of slow compression springs A504, so that the lower connecting plate 503 and the vacuum suction head 505 fixed on the lower bottom surface thereof are in a floating structure in the up-down direction, so that when the vacuum suction head 505 of the pressure head member 50 is driven downward to press down the product 2000 to cover the liquid injection port 201, the pressed product 2000 is not pressed hard, but is pressed downward under the elastic force of the plurality of slow compression springs A504, so that the product 2000 is not easy to be damaged, so that the application has better reliability.

[0113] And, after the resin glue solution attached to the surface of the product 2000 is cured and shaped, the pressure head component 50 can be lifted by a preset stroke through the lifting mechanism 60. In this process, the vacuum suction head 505 still adsorbs the product 2000 and takes the cured and shaped resin glue solution attached to the surface of the product 2000 out of the mold cavity, so as to realize automatic demolding after the resin glue solution in the mold cavity is taken out together. The premise is that the mold cavity is not a special-shaped structure, and the inner surface is not provided with a structure such as a reverse thorn type pit. Then, the vacuum suction head 505 is released from vacuum, and the product 2000 with the resin glue solution on the surface can be caught and taken out by artificial hand or mechanical hand.

[0114] Further, through the above optimization design, the whole application is more convenient, time-saving, safe and reliable to use, and the use effect can be further improved.

[0115] Further, in specific implementation, referring to Figure 7 , Figure 8 , Figure 9 and Figure 10 , according to one embodiment of the application, the pressure head component 50 further comprises a slow pressure spring B506 and a pressure sensor 507 for detecting the pressing force of the product 2000;

[0116] The upper end surface of the lower connecting plate 503 is provided with a clamping groove A5031 in the middle, and the lower bottom surface of the upper connecting plate 501 is provided with a clamping groove B5012 opposite to the clamping groove A5031; the upper part of the pressure sensor 507 is fixedly provided with a fixed pin 5071 with an outer diameter smaller than that of the pressure sensor 507;

[0117] Based on this, in the application, the lower end of the pressure sensor 507 is inserted into the clamping groove A5031; the slow pressure spring B506 in a natural state is arranged between the top of the pressure sensor 507 and the lower bottom surface of the upper connecting plate 501, the upper end of the slow pressure spring B506 is inserted into the clamping groove B5012, and the lower end of the slow pressure spring B506 is fixedly sleeved on the fixed pin 5071.

[0118] Therefore, by arranging the pressure sensor 507, the pressing force of the product 2000 can be detected in real time, so that the pressing force data is controllable; by arranging the slow pressure spring B506, the protection effect of the pressure sensor 507 is good, and the pressure sensor 507 is not easy to be damaged by hard top in the up-down direction.

[0119] Further, in specific implementation, referring to Figure 1 , according to one embodiment of the application, the application further comprises an L-shaped cover 80;

[0120] The L-shaped machine cover 80 is arranged outside the table plate 10 to cover the liquid injection mold 20, the left-right moving mechanism 30, the liquid injection member 40, the pressure head member 50, the lifting mechanism 60 and the front-rear moving mechanism 70, and the L-shaped machine cover 80 is provided with an operation opening 801 in the front middle lower part.

[0121] Therefore, the L-shaped machine cover 80 can better cover the liquid injection mold 20, the left-right moving mechanism 30, the liquid injection member 40, the pressure head member 50, the lifting mechanism 60 and the front-rear moving mechanism 70, so that the protection effect is good, and the operator's hand can be prevented from being injured by the moving structure, and the overall structure of the application is more like a desk, and the overall appearance is beautiful and atmospheric.

[0122] Preferably, in the technical solution, the left-right moving mechanism 30, the liquid injection member 40, the pressure head member 50, the lifting mechanism 60 and the front-rear moving mechanism 70 are controlled by the main controller 90. Figure 1 As shown in the drawings, according to an embodiment of the application, the application further comprises a main controller 90 arranged in the L-shaped machine cover 80 and an optical fiber sensor 100 arranged at the operation opening 801 and connected with the main controller 90.

[0123] When the operator's hand is inserted into the operation opening 801, the optical fiber sensor 100 generates an induction signal and transmits the induction signal to the main controller 90, and the main controller 90 controls the left-right moving mechanism 30, the liquid injection member 40, the pressure head member 50, the lifting mechanism 60 and the front-rear moving mechanism 70 to stop working according to the induction signal.

[0124] Therefore, by arranging the optical fiber sensor 100, when the operator's hand is inserted into the operation opening 801, the optical fiber sensor 100 generates an induction signal and transmits the induction signal to the main controller 90, and the main controller 90 controls the left-right moving mechanism 30, the liquid injection member 40, the pressure head member 50, the lifting mechanism 60 and the front-rear moving mechanism 70 to stop working according to the induction signal, so that the safety and reliability of the application are optimized.

[0125] It should be noted that, in the specific implementation, the left-right moving mechanism 30, the liquid injection member 40, the pressure head member 50, the lifting mechanism 60 and the front-rear moving mechanism 70 are controlled by the main controller 90. Figures 7-10 As shown in the drawings, according to an embodiment of the application, the application further comprises a main controller 90 arranged in the L-shaped machine cover 80 and an optical fiber sensor 100 arranged at the operation opening 801 and connected with the main controller 90. The bottom of the product 2000 to be processed is shaped as a funnel, the upper periphery of the product 2000 is clamped into the limiting ring 5052 in an interference fit, and the inner bottom of the product 2000 is adsorbed by the suction nozzle 5051, so that the product 2000 is quickly and fixedly positioned at the bottom of the vacuum suction head 505.

[0126] At the same time, in comparison Figures 7-10 As shown, the vacuum suction head 505 has a gas inlet / outlet 5053 on its side wall that connects to the suction nozzle 5051. A positioning post 5054 is also provided downwards on the lower surface of the vacuum suction head 505 outside the limiting ring 5052. Figure 2 As shown, the upper end face of the injection mold 20 has a positioning hole 202 facing the positioning post 5054, which is located outside the injection port 201.

[0127] Thus, when the lifting mechanism 60 controls the pressure head component 50 to descend a preset stroke, and the vacuum suction head 505 of the pressure head component 50 presses down the product 2000 to seal the injection port 201, the positioning pin 5054 is inserted into the positioning hole 202 with an interference fit, which can make the pressure head component 50 have a good anti-rotation effect, and make the pressed product 2000 stable and not easy to shift circumferentially.

[0128] Furthermore, in specific implementation, in the tabletop type liquid injection machine 1000 provided according to the embodiments of the present invention, the left and right moving mechanism 30, the lifting mechanism 60 and the front and rear moving mechanism 70 are all preferably screw-driven linear modules or cylinder-driven linear modules, which are common linear guide modules in the prior art, so their details are not described in detail here.

[0129] Other embodiments, etc., will not be described here.

[0130] In summary, the tabletop-type injection machine 1000 provided in this application, in specific implementation, includes the injection component 40. Each time the used resin is used up, the injection mold 20 can be moved to the left to the first position by the left and right moving mechanism 30, so that the injection port 201 is located directly below the injection component 40, so that the mold cavity can receive an appropriate amount of resin flowing down from the injection component 40, thus eliminating the trouble of manually pouring resin into the mold cavity in the traditional way, making this application labor-saving to use.

[0131] Furthermore, the pressure head component 50 provided in this application can play a role in pressing and fixing. By pressing down the product 2000 through the pressure head component 50, the injection port 201 is sealed. At this time, the appropriate amount of resin liquid injected into the mold cavity can be stably attached to the surface of the product 2000. After the product 2000 is pressed and solidified, it is not easy to shift. This allows the resin liquid to be well connected with the position on the surface of the product 2000 that needs to be attached during the curing process, forming an integral whole. As a result, the yield of finished products in this application is high, making it reliable in use.

[0132] In addition, for different injection molds 20, they can be of irregular shapes, and the upper injection ports 201 thereof can not be arranged vertically upward, that is, can be arranged obliquely to face the upper left or upper right. At this time, the locking nut 406 can be loosened, the rotating plate 4041 can be rotated around the rotating shaft 405, the lower end of the injection needle 403 can be adjusted to face the same direction as the opening direction of the upper injection port 201 of the injection mold 20 of irregular shape, and then the locking nut 406 can be tightened. In this way, the injection member 40 of the present application is more flexible to use, and can be used to fill the resin glue into the mold cavity of the injection mold 20 of irregular shape with different opening directions of the injection port 201, so that the use flexibility and adaptability are high.

[0133] Furthermore, the vacuum suction head 505 is arranged to adsorb the product 2000. Thus, when the present application is used, the product 2000 is first adsorbed and fixed on the bottom of the vacuum suction head 505 in a proper direction and angle, and then the injection mold 20 filled with the resin glue is controlled to move to the right to the second position by the left-right moving mechanism 30. The pressing member 50 is controlled to descend by the lifting mechanism 60, and the product 2000 is pressed by the vacuum suction head 505 of the pressing member 50 to cover the injection port 201. At this time, the proper amount of resin glue filled in the mold cavity can be attached to the surface of the pressed product 2000. This process can avoid the manual placement of the product 2000 on the injection port 201, so that the present application is more convenient and safe to operate, and the hand is not easy to be injured by the downward moving pressing member 50.

[0134] Again, the plurality of guide rods 502 and the plurality of buffer springs A 504 are arranged, so that the lower connecting plate 503 and the vacuum suction head 505 fixed on the lower bottom surface thereof are of floating structure in the up-down direction. Thus, when the vacuum suction head 505 of the pressing member 50 is driven downward to press the product 2000 to cover the injection port 201, the pressed product 2000 is not pressed hard, but is pressed downward by the elastic force of the plurality of buffer springs A 504, so that the product 2000 is not easy to be damaged, and the use reliability of the present application is better.

[0135] Furthermore, the table plate type injection machine 1000 provided by the present application has very high practicality and excellent use effect, so that the present application will have good market promotion value, will be very popular, and will be effectively popularized.
