Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding, and particularly relates to an injection molding production mold and an injection molding machine. Background Art

[0002] The related art can produce a workpiece by injecting a thermoplastic material into an injection molding mold in a closed state using an injection molding machine. After production is completed, the related art first uses the injection molding machine to open the injection molding mold, and then removes the workpiece manually or automatically. Since after production is completed, the workpiece is flush with the bottom mold of the injection molding mold or only a local area protrudes from the bottom mold, that is, the graspable area of ​​the workpiece is small, the related art has the problem that it is difficult or even impossible to remove the workpiece manually or automatically due to the small graspable area of ​​the workpiece. Since the injection molding machine can only continue to produce the workpiece after the workpiece is removed, the related art also has the problem that the workpiece removal time is increased due to the difficulty in removing the workpiece, the production efficiency of the injection molding machine is reduced, and the injection molding machine cannot continue to produce the workpiece due to the inability to remove the workpiece.

[0003] Therefore, the prior art needs to be improved and developed. It should be noted that the above information disclosed in this section is only used to understand the background of the concept of the utility model, and therefore may contain information that does not constitute prior art. Utility Model Content

[0004] The purpose of this application is to provide an injection molding production mold and an injection molding machine, which can effectively solve the problem that it is difficult or even impossible to remove the workpiece manually or automatically due to the small graspable area of ​​the workpiece, thereby effectively solving the problem that the workpiece removal time increases due to the difficulty in removing the workpiece, the production efficiency of the injection molding machine decreases, and the injection molding machine cannot continue to produce the workpiece due to the inability to remove the workpiece.

[0005] In a first aspect, the present application provides an injection mold for producing injection molded parts, which is used in an injection molding machine. The injection mold for producing injection molded parts includes:

[0006] bottom mold;

[0007] The mold core is slidably mounted on the bottom mold;

[0008] Injection tube, slidably mounted on the bottom mold;

[0009] The first driving mechanism is used to drive the mold core to slide relative to the bottom mold to separate the workpiece in the bottom mold from the mold core;

[0010] The second driving mechanism is used to drive the injection tube to move toward the workpiece after the workpiece is separated from the mold core, so as to eject the workpiece out of the bottom mold.

[0011] The present application provides an injection molding production mold, which first separates the workpiece in the bottom mold from the mold core by utilizing a first drive mechanism to drive the mold core to slide relative to the bottom mold, and then pushes the workpiece out of the bottom mold by utilizing a second drive mechanism to drive the injection molding tube to move toward the workpiece. That is, the present application is equivalent to increasing the graspable area of ​​the workpiece through the cooperation of the first drive mechanism and the second drive mechanism, so that the graspable area of ​​the workpiece of the present application is larger than the graspable area of ​​the workpiece of the prior art. Therefore, the present application can effectively solve the problem that it is difficult or even impossible to remove the workpiece manually or automatically due to the small graspable area of ​​the workpiece, thereby effectively solving the problem that the workpiece removal time increases due to the difficulty in removing the workpiece, the production efficiency of the injection molding machine decreases, and the injection molding machine cannot continue to produce the workpiece due to the inability to remove the workpiece.

[0012] Furthermore, the injection molding production mold also includes a top mold, a first mounting plate and a second mounting plate, the bottom mold is fixed on the first mounting plate, the top mold is fixed on the second mounting plate, the first driving mechanism includes a first pull rod, one end of the first pull rod is fixedly connected to the first mounting plate, the first pull rod is slidably mounted on the second mounting plate, and a top mold moving mechanism is installed on the injection molding machine. The top mold moving mechanism is used to drive the second mounting plate to move so as to separate the bottom mold from the top mold, and after the bottom mold is separated from the top mold, the other end of the first pull rod is in contact with the second mounting plate to drive the first mounting plate to move.

[0014] The first supporting assembly of this technical solution can support the second mounting plate. This technical solution can effectively avoid the deformation of the second mounting plate due to excessive force applied to the second mounting plate during the injection molding process, resulting in the final workpiece having a flash.

[0015] Furthermore, the injection molding production mold also includes a glue injection plate, a fourth mounting plate, a second pull rod and a nylon rod. The glue injection plate has a glue injection port. One end of the second pull rod is fixedly connected to the glue injection plate. The second pull rod is slidably mounted on the fourth mounting plate. The other end of the second pull rod has a first limiting chamfer that can be inverted on the fourth mounting plate. A guide plate is slidably mounted on the fourth mounting plate. A guide groove is provided on the guide plate. The injection tube is fixed on the guide plate and connected to the glue injection port through the guide groove. The second driving mechanism is connected to the guide plate. The second driving mechanism is used to drive the guide plate to move toward or away from the workpiece. The mold core is fixed on the fourth mounting plate. The nylon rod is slidably mounted on the first mounting plate and fixedly connected to the fourth mounting plate.

[0016] Since this technical solution can use the injection molding machine as a power source for separating the mold core from the workpiece and separating the fourth mounting plate from the injection plate by setting a first pull rod, a second pull rod and a nylon rod, this technical solution does not need to set up a separate power source for separating the mold core from the workpiece and separating the fourth mounting plate from the injection plate, thereby effectively saving the production cost of the injection molding mold and simplifying the structure of the injection molding mold.

[0018] This technical solution is equivalent to first separating the top mold from the bottom mold, then separating the fourth mounting plate from the sixth mounting plate, then separating the sixth mounting plate from the fifth mounting plate, and finally separating the first mounting plate from the fourth mounting plate. Since this technical solution can separate the agglomerate from the injection port in the injection mold by separating the fifth mounting plate from the sixth mounting plate, this technical solution can effectively avoid the situation where the agglomerate is difficult to remove due to the agglomerate sticking to the injection port.

Therefore, this technical solution can effectively avoid unexpected situations such as the top mold being unable to close with the bottom mold due to accidental offset of the first mounting plate, the second mounting plate, the fourth mounting plate, the fifth mounting plate and the sixth mounting plate during the sliding process.

[0021] Furthermore, the injection mold production mold also includes a second support assembly, which is slidably mounted on the guide plate and fixedly connected to the fourth mounting plate.

[0022] The second supporting assembly of this technical solution can support the fourth mounting plate.

[0023] Furthermore, there are multiple injection molding tubes, which are arranged in a rectangular array on the guide plate, and a mold core is provided in each injection molding tube.

[0025] Furthermore, the second driving mechanism includes a plurality of oil cylinders, which are symmetrically mounted on the fourth mounting plate with the center of the fourth mounting plate as the symmetrical center and are all connected to the guide plate.

[0027] The present application provides an injection molding machine, which first separates the workpiece in the bottom mold from the mold core by utilizing a first drive mechanism to drive the mold core to slide relative to the bottom mold, and then pushes the workpiece out of the bottom mold by utilizing a second drive mechanism to drive the injection molding tube to move toward the workpiece. That is, the present application is equivalent to increasing the graspable area of ​​the workpiece through the cooperation of the first drive mechanism and the second drive mechanism, so that the graspable area of ​​the workpiece of the present application is larger than the graspable area of ​​the workpiece of the prior art. Therefore, the present application can effectively solve the problem that it is difficult or even impossible to remove the workpiece manually or automatically due to the small graspable area of ​​the workpiece, thereby effectively solving the problem that the removal time of the workpiece is increased due to the difficulty in removing the workpiece, the production efficiency of the injection molding machine is reduced, and the injection molding machine cannot continue to produce the workpiece due to the inability to remove the workpiece.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0034] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0035] First, as Figure 1-Figure 3 As shown, the present application provides an injection mold production mold, which is used in an injection molding machine. The injection mold production mold includes:

[0036] Bottom mold 1;

[0037] The mold core 2 is slidably mounted on the bottom mold 1;

[0038] The injection tube 3 is slidably mounted on the bottom mold 1;

[0039] The first driving mechanism 4 is used to drive the mold core 2 to slide relative to the bottom mold 1 so as to separate the workpiece 5 in the bottom mold 1 from the mold core 2;

[0040] The second driving mechanism 6 is used to drive the injection tube 3 to move toward the workpiece 5 after the workpiece 5 is separated from the mold core 2, so as to eject the workpiece 5 out of the bottom mold 1.

[0041] The present application provides a mold for producing an injection molded part, which is used in an injection molding machine. The mold for producing an injection molded part is particularly suitable for producing a perfume bottle cap. Specifically, the perfume bottle cap of this embodiment has a groove, and the mold core 2 of this embodiment contacts the side wall and the top wall of the groove of the perfume bottle cap (refer to Figure 2), this embodiment can use an injection molding machine to open or close the mold for producing injection molded parts. The mold for producing injection molded parts in this embodiment includes a bottom mold 1 and a top mold 7. Specifically, when the mold for producing injection molded parts is in the open mold state, the bottom mold 1 and the top mold 7 are separated, and when the mold for producing injection molded parts is in the closed mold state, the bottom mold 1 and the top mold 7 are closed. The bottom mold 1 of this embodiment is the mold where the workpiece 5 is located when the mold for producing injection molded parts is in the open mold state. The mold core 2 and the injection tube 3 of this embodiment are both slidably mounted on the bottom mold 1, that is, the mold core 2 and the injection tube 3 of this embodiment can slide equivalently to the bottom mold 1. The first driving mechanism 4 of this embodiment can be a mechanism such as an electric cylinder or an oil cylinder that can actively drive the movement of an object. The first driving mechanism 4 of this embodiment can also be a mechanism such as a transmission mechanism that can drive the movement of an object under the action of an external force. Specifically, the first driving mechanism 4 of this embodiment can drive the mold core 2 to slide relative to the bottom mold 1 by driving the mold core 2 or the bottom mold 1 to move. It should be understood that after the workpiece 5 is formed, the workpiece 5 will adhere to the mold core 2, that is, there is an adhesive force between the workpiece 5 and the mold core 2, and when the mold core 2 slides relative to the bottom mold 1, the workpiece 5 will be subjected to an external force sufficient to overcome the adhesive force. Therefore, this embodiment can separate the workpiece 5 in the bottom mold 1 from the mold core 2 by utilizing the first driving mechanism 4 to drive the mold core 2 to slide relative to the bottom mold 1. The second driving mechanism 6 of this embodiment can be a mechanism such as an electric cylinder or an oil cylinder that can actively drive the movement of an object. The second driving mechanism 6 of this embodiment can drive the injection molding tube 3 to move toward or away from the workpiece 5. Since there is no adhesion between the workpiece 5 and the mold core 2 after the workpiece 5 is separated from the mold core 2, this embodiment only needs to provide the workpiece 5 with an external force away from the bottom mold 1 to move the workpiece 5 away from the bottom mold 1. This embodiment can provide the workpiece 5 with an external force away from the bottom mold 1 by using the second driving mechanism 6 to drive the injection molding tube 3 toward the workpiece 5. Therefore, this embodiment can eject the workpiece 5 by using the second driving mechanism 6 to drive the injection molding tube 3 toward the workpiece 5 after the workpiece 5 is separated from the mold core 2.It should be understood that when the first driving mechanism 4 drives the mold core 2 to slide relative to the bottom mold 1, the external force applied to the workpiece 5 acts on the side walls and top walls of the workpiece 5. When the second driving mechanism 6 drives the injection molding tube 3 to move toward the workpiece 5, the force applied to the workpiece 5 only acts on the top wall of the workpiece 5, and the force that separates the workpiece 5 in the bottom mold 1 from the mold core 2 is greater than the force that ejects the workpiece 5 out of the bottom mold 1. If the separation of the workpiece 5 in the bottom mold 1 from the mold core 2 and the ejection of the workpiece 5 from the bottom mold 1 are achieved only by driving the injection molding tube 3 toward the workpiece 5, the top wall of the workpiece 5 may be penetrated due to the excessive force applied to the top wall of the workpiece 5, thereby resulting in defective products. Therefore, this embodiment needs to first separate the workpiece 5 in the bottom mold 1 from the mold core 2 by using the first driving mechanism 4 to drive the mold core 2 to slide relative to the bottom mold 1, and then eject the workpiece 5 out of the bottom mold 1 by using the second driving mechanism 6 to drive the injection molding tube 3 toward the workpiece 5.

[0042] The specific process for producing the workpiece 5 in this embodiment can be as follows: using an injection molding machine to close the injection molding mold; using the injection molding machine and the injection molding tube 3 to inject thermoplastic material into the space surrounded by the top mold 7, the bottom mold 1, and the mold core 2; cooling the injection molding mold to form the workpiece 5 in the injection molding mold; using the injection molding machine to open the injection molding mold; controlling the first drive mechanism 4 to drive the mold core 2 to slide relative to the bottom mold 1 to separate the workpiece 5 in the bottom mold 1 from the mold core 2; controlling the second drive mechanism 6 to drive the injection molding tube 3 to move toward the workpiece 5 to eject the workpiece 5 from the bottom mold 1; removing the workpiece 5 manually or automatically; and controlling the first drive mechanism 4, the second drive mechanism 6, and the injection molding machine to reset. It should be understood that after the first drive mechanism 4, the second drive mechanism 6, and the injection molding machine are reset, this embodiment can continue to produce the workpiece 5.

[0043] The present application provides an injection molding production mold, which first separates the workpiece 5 in the bottom mold 1 from the mold core 2 by utilizing a first drive mechanism 4 to drive the mold core 2 to slide relative to the bottom mold 1, and then pushes the workpiece 5 out of the bottom mold 1 by utilizing a second drive mechanism 6 to drive the injection molding tube 3 to move toward the workpiece 5. That is, the present application is equivalent to increasing the graspable area of ​​the workpiece 5 through the cooperation of the first drive mechanism 4 and the second drive mechanism 6, so that the graspable area of ​​the workpiece 5 of the present application is larger than the graspable area of ​​the workpiece 5 of the prior art. Therefore, the present application can effectively solve the problem that it is difficult or even impossible to remove the workpiece 5 manually or automatically due to the small graspable area of ​​the workpiece 5, thereby effectively solving the problem that the removal time of the workpiece 5 is increased due to the difficulty in removing the workpiece 5, the production efficiency of the injection molding machine is reduced, and the injection molding machine cannot continue to produce the workpiece 5 due to the inability to remove the workpiece 5.

[0044] In some preferred embodiments, the injection mold production mold further includes a top mold 7, a first mounting plate 8, and a second mounting plate 9, the bottom mold 1 is fixed to the first mounting plate 8, the top mold 7 is fixed to the second mounting plate 9, the first driving mechanism 4 includes a first tie rod, one end of the first tie rod is fixedly connected to the first mounting plate 8, and the first tie rod is slidably mounted on the second mounting plate 9, and the injection molding machine is installed with a top mold moving mechanism (not shown in the figure), the top mold moving mechanism is used to drive the second mounting plate 9 to move to separate the bottom mold 1 from the top mold 7, and after the bottom mold 1 and the top mold 7 are separated, the other end of the first tie rod is in contact with the second mounting plate 9 to drive the first mounting plate 8 to move. Specifically, when the injection mold production mold is in the mold closing state, the other end of the first tie rod does not conflict with the second mounting plate 9. Since one end of the first pull rod in this embodiment is fixedly connected to the first mounting plate 8, the first pull rod is slidably mounted on the second mounting plate 9. When the top mold moving mechanism drives the second mounting plate 9 to move away from the first mounting plate 8, the second mounting plate 9 will slide along the first pull rod to the other end of the first pull rod and collide with the second mounting plate 9. After the other end of the first pull rod collide with the second mounting plate 9, the top mold moving mechanism continues to drive the second mounting plate 9 away from the first mounting plate 8 to move. At this time, the top mold moving mechanism provides an external force sufficient to overcome the adhesion between the workpiece 5 and the mold core 2 to the workpiece 5 through the second mounting plate 9, the first pull rod and the first mounting plate 8. Therefore, this embodiment can separate the workpiece 5 in the bottom mold 1 from the mold core 2 by utilizing the top mold moving mechanism to drive the second mounting plate 9 away from the first mounting plate 8. That is, this embodiment is equivalent to separating the workpiece 5 from the mold core 2 during the process of opening the injection molding production mold. That is, this embodiment is equivalent to using the injection molding machine as the power source to separate the workpiece 5 in the bottom mold 1 from the mold core 2 and using the transmission mechanism as the first driving mechanism 4.

[0045] In some preferred embodiments, the mold for producing injection molded parts further includes a third mounting plate 10 and a first support assembly 11. The third mounting plate 10 is connected to the top mold moving mechanism, the second mounting plate 9 is fixedly connected to the third mounting plate 10, and the ends of the first support assembly 11 are respectively fixedly connected to the second mounting plate 9 and the third mounting plate 10. The mold for producing injection molded parts in this embodiment further includes the third mounting plate 10 and the first support assembly 11. The first support assembly 11 in this embodiment can support the second mounting plate 9. This embodiment can effectively prevent the second mounting plate 9 from deforming due to excessive force applied to the second mounting plate 9 during the injection molding process, thereby preventing the final workpiece 5 from having a flash.

[0046] In some preferred embodiments, the injection molding production mold also includes a glue injection plate 12, a fourth mounting plate 13, a second pull rod 14 and a nylon rod 15. The glue injection plate 12 has a glue injection port 16. One end of the second pull rod 14 is fixedly connected to the glue injection plate 12. The second pull rod 14 is slidably mounted on the fourth mounting plate 13. The other end of the second pull rod 14 has a limiting chamfer that can be inverted on the fourth mounting plate 13. A guide plate 17 is slidably mounted on the fourth mounting plate 13. The guide plate 17 is provided with a guide groove. The injection tube 3 is fixed on the guide plate 17 and is connected to the glue injection port 16 through the guide groove. The second driving mechanism 6 is connected to the guide plate 17. The second driving mechanism 6 is used to drive the guide plate 17 to move toward or away from the workpiece 5. The mold core 2 is fixed on the fourth mounting plate 13. The nylon rod 15 is slidably mounted on the first mounting plate 8 and fixedly connected to the fourth mounting plate 13. The glue injection plate 12 of this embodiment is fixed on the injection molding machine. The nylon rod 15 of this embodiment is slidably mounted on the first mounting plate 8 and fixedly connected to the fourth mounting plate 13. The nylon rod 15 can prevent the first mounting plate 8 from separating from the fourth mounting plate 13, that is, this embodiment is equivalent to forming a binding force between the first mounting plate 8 and the fourth mounting plate 13 by setting the nylon rod 15. Since one end of the second pull rod 14 of this embodiment is fixedly connected to the glue injection plate 12, the second pull rod 14 is slidably mounted on the fourth mounting plate 13, and the other end of the second pull rod 14 has a first limiting chamfer that can be buckled on the fourth mounting plate 13, when the second mounting plate 9 drives the first mounting plate 8 to move through the first pull rod, the nylon rod 15 can prevent the first mounting plate 8 from separating from the fourth mounting plate 13, so that the fourth mounting plate 13 moves with the first mounting plate 8. At this time, the fourth mounting plate 13 will slide along the second pull rod 14 to realize the fourth mounting plate 13 and the glue injection plate 12. The separation is achieved by separating the condensate in the injection molding production mold (the condensate is formed after the thermoplastic material located in the injection molding tube 3, the guide plate 17 and the glue injection plate 12 is cooled) from the injection molding tube 3 and the guide plate 17. It should be understood that after the fourth mounting plate 13 is separated from the glue injection plate 12, this embodiment can remove the condensate in the injection molding production mold manually or automatically to avoid the situation where the thermoplastic material cannot be injected into the space surrounded by the top mold 7, the bottom mold 1 and the core 2 due to the presence of condensate in the injection molding production mold, and the workpiece 5 cannot be produced.It should be understood that since the injection plate 12 of this embodiment is fixed on the injection molding machine, when the fourth mounting plate 13 slides to the first limit chamfer of the second pull rod 14 and is buckled on the fourth mounting plate 13, the fourth mounting plate 13 cannot continue to move with the first mounting plate 8. At this time, the external force provided by the injection molding machine to the first mounting plate 8 is sufficient to overcome the bonding force formed between the first mounting plate 8 and the fourth mounting plate 13, and the fourth mounting plate 13 is separated from the first mounting plate 8, thereby realizing the separation of the mold core 2 and the workpiece 5, that is, after the first limit chamfer of the second pull rod 14 is buckled on the fourth mounting plate 13, the nylon rod 15 cannot prevent the separation of the first mounting plate 8 and the fourth mounting plate 13, that is, when using the injection molding machine to open the mold for the production of injection molded parts, this embodiment first separates the top mold 7 from the bottom mold 1, then separates the fourth mounting plate 13 from the injection plate 12, and finally separates the mold core 2 from the workpiece 5 in the bottom mold 1. Since this embodiment can use the injection molding machine as a power source for separating the mold core 2 from the workpiece 5 in the bottom mold 1 and separating the fourth mounting plate 13 from the injection plate 12 by setting a first pull rod, a second pull rod 14 and a nylon rod 15, this embodiment does not need to set up a separate power source for separating the mold core 2 from the workpiece 5 in the bottom mold 1 and separating the fourth mounting plate 13 from the injection plate 12, thereby effectively saving the production cost of the injection molding production mold and simplifying the structure of the injection molding production mold.

[0047] In some preferred embodiments, the glue injection plate 12 includes a fifth mounting plate 121 and a sixth mounting plate 122, the glue injection port 16 is arranged on the fifth mounting plate 121, one end of the second pull rod 14 is fixedly connected to the sixth mounting plate 122, and the injection molding production mold also includes a third pull rod 18, one end of the third pull rod 18 is fixedly connected to the fifth mounting plate 121, the third pull rod 18 is slidably installed on the sixth mounting plate 122, and the other end of the third pull rod 18 has a second limiting chamfer that can be inverted on the fifth mounting plate 121, and a through hole is provided on the sixth mounting plate 122, and the injection tube 3 is connected to the glue injection port 16 through the drainage groove and the through hole. After the first limiting chamfer of the second tie rod 14 is buckled on the fourth mounting plate 13, the third tie rod 18 will slide along the fifth mounting plate 121 to the second limiting chamfer and buckle on the fifth mounting plate 121. After the second limiting chamfer of the third tie rod 18 is buckled on the fifth mounting plate 121, the nylon rod 15 cannot prevent the first mounting plate 8 from separating from the fourth mounting plate 13. That is, this embodiment is equivalent to first separating the top mold 7 from the bottom mold 1, then separating the fourth mounting plate 13 from the sixth mounting plate 122, and then separating the sixth mounting plate 122 from the fifth mounting plate 121, and finally separating the first mounting plate 8 from the fourth mounting plate 13 (equivalent to separating the mold core 2 from the workpiece 5 in the bottom mold 1). Since this embodiment can separate the slurry from the injection port 16 in the injection mold for the injection molded part by separating the fifth mounting plate 121 from the sixth mounting plate 122, this embodiment can effectively avoid the situation where the slurry is difficult to remove due to adhesion of the slurry in the injection port 16.

[0048] In some preferred embodiments, the injection mold production mold further includes a plurality of guide shafts 19, which are arranged in a rectangular array on the fifth mounting plate 121. The first mounting plate 8, the second mounting plate 9, the fourth mounting plate 13, the fifth mounting plate 121, and the sixth mounting plate 122 are all slidably connected to the guide shafts 19. The number of guide shafts 19 in this embodiment is preferably four, and the guide shafts 19 in this embodiment are preferably also slidably connected to the third mounting plate 10. The guide shafts 19 in this embodiment can guide the sliding of the first mounting plate 8, the second mounting plate 9, the third mounting plate 10, the fourth mounting plate 13, the fifth mounting plate 121, and the sixth mounting plate 122. Therefore, this embodiment can effectively avoid unexpected situations such as the top mold 7 being unable to close with the bottom mold 1 due to accidental offset of the first mounting plate 8, the second mounting plate 9, the third mounting plate 10, the fourth mounting plate 13, the fifth mounting plate 121, and the sixth mounting plate 122 during the sliding process.

[0049] In some preferred embodiments, the injection mold further includes a second support assembly 20, which is slidably mounted on the guide plate 17 and fixedly connected to the fourth mounting plate 13. The second support assembly 20 of this embodiment is preferably composed of a plurality of support columns. The second support assembly 20 of this embodiment can support the fourth mounting plate 13. This embodiment can effectively prevent the fourth mounting plate 13 from being deformed due to excessive force applied to the fourth mounting plate 13 during the injection molding process, resulting in flashing of the final workpiece 5.

[0050] In some preferred embodiments, there are multiple injection molding tubes 3, which are arranged in a rectangular array on the guide plate 17. Each injection molding tube 3 is provided with a mold core 2. In this embodiment, the number of injection molding tubes 3 and mold cores 2 is preferably four. This embodiment is equivalent to simultaneously producing multiple workpieces 5 by arranging multiple injection molding tubes 3 and multiple mold cores 2 on the guide plate 17. Therefore, this embodiment can effectively improve the production efficiency of the workpieces 5.

[0051] In some preferred embodiments, the second drive mechanism 6 includes a plurality of oil cylinders, which are symmetrically mounted on the fourth mounting plate 13 with the center of the fourth mounting plate 13 as the center of symmetry and are all connected to the guide plate 17. The second drive mechanism 6 of this embodiment preferably includes two oil cylinders. Since the plurality of oil cylinders of this embodiment are symmetrically mounted on the fourth mounting plate 13 with the center of the fourth mounting plate 13 as the center of symmetry and are all connected to the guide plate 17, this embodiment can evenly apply force to the guide plate 17, thereby effectively improving the sliding stability of the guide plate 17 and avoiding the situation in which the workpiece 5 cannot be ejected from the bottom mold 1 due to uneven force on the guide plate 17.

[0052] As can be seen from the above, the present application provides an injection molding production mold, which first separates the workpiece 5 from the mold core 2 by utilizing the first drive mechanism 4 to drive the mold core 2 to slide relative to the bottom mold 1, and then pushes the workpiece 5 out of the bottom mold 1 by utilizing the second drive mechanism 6 to drive the injection molding tube 3 to move toward the workpiece 5, that is, the present application is equivalent to increasing the graspable area of ​​the workpiece 5 through the cooperation of the first drive mechanism 4 and the second drive mechanism 6, so that the graspable area of ​​the workpiece 5 of the present application is larger than the graspable area of ​​the workpiece 5 of the prior art. Therefore, the present application can effectively solve the problem that it is difficult or even impossible to remove the workpiece 5 manually or automatically due to the small graspable area of ​​the workpiece 5, thereby effectively solving the problem that the removal time of the workpiece 5 is increased due to the difficulty in removing the workpiece 5, the production efficiency of the injection molding machine is reduced, and the injection molding machine cannot continue to produce the workpiece 5 due to the inability to remove the workpiece 5.

[0053] In a second aspect, the present invention provides an injection molding machine, which includes an injection molding mold provided in the first aspect.
