Description

Technical Field

[0001] This invention relates to the field of injection mold technology, specifically to an injection mold for processing cosmetic bottles and its usage method. Background Technology

[0002] Injection molds for cosmetic bottle processing are core equipment to ensure the molding accuracy and surface finish of the bottle. The stability of multi-cavity synchronous injection directly affects production efficiency and product consistency. The moving mold of the mold is equipped with multiple insert rods, which cooperate with the fixed mold cavity to form multiple independent injection spaces when the mold is closed.

[0003] In continuous injection molding, to ensure that the molded cosmetic bottle can be smoothly detached from the insert, a release agent needs to be evenly applied to the surface of the insert. However, due to the large number of inserts, the existing operation requires manual application to each insert one by one, resulting in extremely low efficiency. During continuous production, frequent manual application requires repeated machine stops, reducing the effective operating rate of the equipment. Furthermore, manual operation is prone to uneven application and missed application, causing some bottles to stick together or have surface scratches during demolding, further reducing the product qualification rate. Based on this, the present invention purposefully provides an injection mold for cosmetic bottle processing that facilitates efficient application of release agent to multiple sets of inserts and its method of use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing an injection mold for cosmetic bottle processing and its usage method, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An injection mold for processing cosmetic bottles, comprising:

[0007] A base is provided, on which a fixed mold and a hydraulic rod are fixedly mounted. A movable mold is fixedly mounted at the movable end of the hydraulic rod. The movable mold is slidably mounted on the base. Guide rods are fixedly mounted at both ends of the movable mold. The guide rods are slidably connected to the fixed mold. Multiple equally spaced insert rods are fixedly mounted on the side of the movable mold facing the fixed mold. Multiple equally spaced cavities are opened on the side of the fixed mold facing the movable mold. The cavities match the insert rods. An injection port is connected to the side of the fixed mold away from the movable mold. The injection port is connected to an external injection molding device and to multiple cavities.

[0008] A push plate is provided, which has multiple through slots corresponding to the insert rods. The through slots are slidably connected to the insert rods. An electric cylinder is fixedly installed on the moving mold. The movable end of the electric cylinder is fixedly connected to the push plate. A fixing plate is fixedly installed on the side of the push plate near the moving mold. A spraying component is provided on the fixing plate. The spraying component is used to spray the release agent onto the outer surface of each insert rod. A coating component is provided on the push plate. The coating component is located between the fixing plate and the push plate. The coating component is used to evenly coat the release agent onto the outer surface of the insert rod.

[0009] As a further aspect of the present invention: the spraying assembly includes a spraying component and an infusion pipe. There are multiple spraying components, each of which is fixedly installed on a fixed plate and sleeved on a plug rod. Each spraying component is connected to an external infusion device through an infusion pipe. The inner wall of the spraying component is connected to multiple circumferentially arranged nozzles, which face the outer circular surface of the plug rod.

[0010] As a further embodiment of the present invention: the application assembly includes a sleeve, an annular brush, a side plate, a drive wheel, and a synchronization component. Each insertion rod has a corresponding sleeve, which is rotatably mounted on a push plate. An annular brush is embedded in each sleeve, and the annular brush is in contact with the insertion rod and slidably connected to it. Two adjacent sleeves at the same horizontal level are connected by a first synchronous belt. The side plate is fixedly mounted on the push plate, and multiple drive wheels are rotatably mounted on the side plate. Two adjacent drive wheels are connected by a second synchronous belt. Sleeves at different horizontal levels are connected to the drive wheels by a third synchronous belt. One drive wheel is driven to rotate by the synchronization component.

[0011] As a further aspect of the present invention: the synchronization component includes a transmission gear, a transmission rod, a ratchet assembly, and a rack plate. The transmission gear and the transmission rod are both rotatably mounted on the side plate, and the transmission gear is sleeved on the transmission rod. The transmission gear is connected to the transmission rod via the ratchet assembly. The rack plate is fixedly mounted on the moving mold and meshes with the transmission gear. The transmission rod is connected to the drive wheel via the transmission assembly. When the electric cylinder extends and drives the push plate away from the moving mold, the rack plate causes the transmission gear to rotate. At this time, the ratchet assembly keeps the transmission rod stationary. When the electric cylinder retracts and drives the push plate closer to the moving mold, the rack plate causes the transmission gear to rotate. At this time, the ratchet assembly causes the transmission rod and the transmission gear to rotate synchronously.

[0012] As a further embodiment of the present invention: the transmission assembly includes a first bevel gear and a second bevel gear, both of which are rotatably mounted in the side plate. The first bevel gear meshes with the second bevel gear, and their axes are perpendicular. The first bevel gear is coaxially and fixedly connected to the transmission rod, and the second bevel gear is coaxially and fixedly connected to the drive wheel.

[0013] As a further aspect of the present invention: the top of the fixed mold is connected to a circulation inlet and a circulation outlet, a cooling channel is provided inside the fixed mold, the two ends of the cooling channel are respectively connected to the circulation inlet and the circulation outlet, and the circulation inlet and the circulation outlet are connected to an external cooling circulation component.

[0014] As a further aspect of the present invention: a discharge port is provided on the base, and a discharge plate is slidably installed in the discharge port. The discharge plate is driven by an output source to move up and down. A discharge cavity is provided on the base, and the discharge cavity is connected to the discharge port. The discharge port faces the inlet end of the discharge cavity. The horizontal height of the inlet end of the discharge cavity is higher than the horizontal height of the outlet end of the discharge cavity, and the inlet end of the discharge cavity is close to the discharge port. When the hydraulic rod retracts to separate the moving mold and the fixed mold, the electric cylinder extends to move the push plate away from the moving mold. At this time, the push plate moves away from the insert rod, and the output source drives the discharge plate to rise and discharge the bottle on the push plate to the discharge port.

[0015] A method for using an injection mold for processing cosmetic bottles, the method being applied to the injection mold for processing cosmetic bottles as described above, the method comprising the following steps:

[0016] Step S1: First, ensure that the moving mold and the fixed mold are in the mold separation state. Drive the push plate away from the moving mold using an electric cylinder, and let the push plate slide to the end of the insert rod away from the moving mold.

[0017] Step S2: Subsequently, as the electric cylinder retracts and drives the push plate closer to the moving mold, the release agent is sprayed onto the outer surface of each insert rod through the spraying component. At the same time, the coating component spreads the release agent sprayed on the outer surface of the insert rod evenly, and the release agent is manually sprayed into the cavity.

[0018] Step S3: Immediately afterwards, the hydraulic rod extends to close the moving mold and the fixed mold, so that the push plate closes with the fixed mold, and the insert rod is inserted into the cavity;

[0019] Step S4: The external injection molding equipment injects the raw material into the cavity through the injection port. At this time, the raw material wraps around the insert and fills the cavity. Wait for a period of time for the bottle to be formed.

[0020] Step S5: The moving mold and the fixed mold are separated by the hydraulic rod. The bottle body is sleeved on the insert rod and moved out of the cavity. Then, step S1 is repeated. The push plate slides to the end of the insert rod away from the moving mold. During this process, the bottle body will be pushed away from the insert rod, thereby completing the operation of unloading all the bottles.

[0021] The beneficial effects of this invention are:

[0022] 1. In this invention, by setting a push plate on the moving mold and setting a spraying component and a coating component on the push plate, when the moving mold and the fixed mold are separated, the push plate can unload the bottle on each insert when it moves away from the moving mold, and when the push plate returns to the moving mold and moves closer to the moving mold, it can spray the release agent on each insert at the same time and coat it evenly, thus achieving the purpose of synchronous coating. This avoids the problem of needing too long a downtime operation due to manual coating of each insert, as well as the problem of difficulty in coating the inserts in the middle area due to the obstruction of external inserts.

[0023] 2. In this invention, a circulation inlet, a circulation outlet, and a cooling channel are provided on the fixed mold to communicate with an external cooling circulation component. The cooling medium is injected through the circulation inlet, circulates inside the fixed mold through the cooling channel, and then flows out from the circulation outlet. In this way, the cooling medium accelerates the heat exchange with the high-temperature raw material in the cavity, thereby shortening the cooling time.

[0024] 3. In this invention, when the hydraulic rod retracts to separate the moving mold from the fixed mold, the electric cylinder extends to move the push plate away from the moving mold. At this time, the push plate moves the bottle away from the insert rod. The bottle is then located at the discharge port. Then, the output source drives the discharge plate to rise. The top of the discharge plate rises in contact with the push plate, thereby scraping the bottle off the push plate and discharging the bottle from the push plate to the discharge port. This avoids contact between the push plate and the bottle opening, which would otherwise cause the bottle to remain attached to the push plate after the push plate pushes the bottle away from the insert rod, resulting in some bottles not being able to be discharged.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] Please see Figures 1-8 As shown, the present invention is an injection mold for processing cosmetic bottles, comprising:

[0037] A base 1 is provided, on which a fixed mold 2 and a hydraulic rod 4 are fixedly installed. A movable mold 3 is fixedly installed at the movable end of the hydraulic rod 4. The movable mold 3 is slidably installed on the base 1. Guide rods 5 are fixedly installed at both ends of the movable mold 3. The guide rods 5 are slidably connected to the fixed mold 2. Multiple equally spaced insert rods 6 are fixedly installed on the side of the movable mold 3 facing the fixed mold 2. Multiple equally spaced cavities 7 are opened on the side of the fixed mold 2 facing the movable mold 3. The cavities 7 are matched with the insert rods 6. An injection port 8 is connected to the side of the fixed mold 2 away from the movable mold 3. The injection port 8 is connected to an external injection molding equipment and to the multiple cavities 7.

[0038] A push plate 12 is provided with multiple through slots corresponding to the insert rods 6. The through slots are slidably connected to the insert rods 6. An electric cylinder 13 is fixedly installed on the moving mold 3. The movable end of the electric cylinder 13 is fixedly connected to the push plate 12. A fixing plate 14 is fixedly installed on the side of the push plate 12 near the moving mold 3. A spraying assembly is provided on the fixing plate 14. The spraying assembly is used to spray the release agent onto the outer surface of each insert rod 6. A coating assembly is provided on the push plate 12. The coating assembly is located between the fixing plate 14 and the push plate 12. The coating assembly is used to evenly coat the release agent onto the outer surface of the insert rods 6.

[0039] In one embodiment of this invention, it should be noted that the external injection molding equipment described in this invention can be a horizontal injection molding machine. The external injection molding equipment, hydraulic rod 4, and electric cylinder 13 are all prior art. This invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of this invention.

[0040] The working principle of this invention is as follows: First, ensure that the moving mold 3 and the fixed mold 2 are in the mold-separation state. Then, drive the push plate 12 away from the moving mold 3 using an electric cylinder 13, allowing the push plate 12 to slide onto the insert rod 6 at the end away from the moving mold 3. This allows the spraying assembly to spray the release agent starting from the end of the insert rod 6 away from the moving mold 3. Subsequently, as the electric cylinder 13 retracts, driving the push plate 12 closer to the moving mold 3, the spraying assembly sprays the release agent onto the outer surface of each insert rod 6. Simultaneously, the coating assembly evenly coats the release agent sprayed onto the outer surface of the insert rod 6. Release agent is manually sprayed into the cavity 7, thus simultaneously coating the outer surfaces of all the insert rods 6. Then, the hydraulic rod 4 extends, causing the moving mold 3 and the fixed mold 2 to close, closing the push plate 12 with the fixed mold 2, and inserting the insert rods 6 into the cavity 7. At this time, the external injection molding equipment injects raw material into the cavity 7 through the injection port 8. The raw material then wraps around the insert rods 6 and fills the cavity 7. After a period of time, the bottle body is formed. The hydraulic rod 4 then separates the moving mold 3 and the fixed mold 2, and the bottle body, fitted onto the insert rods 6, is removed from the cavity 7. Subsequently, the electric cylinder 1... 3. The pusher plate 12 slides to the end of the insert rod 6 away from the moving mold 3. This is not only to allow the spraying assembly to spray the release agent from the end of the insert rod 6 away from the moving mold 3, but more importantly, the sliding of the pusher plate 12 pushes the bottle away from the insert rod 6, thus completing the removal of all bottles from the insert rod 6 and achieving synchronous feeding. Then, as the electric cylinder 13 retracts and drives the pusher plate 12 closer to the moving mold 3, the spraying assembly sprays the release agent onto the outer surface of each insert rod 6, and at the same time, the coating assembly coats the release agent sprayed onto the outer surface of the insert rod 6. Once the mixture is spread evenly, the next round of processing of the cosmetic bottle body can begin. It is important to note that in order to ensure that the bottle body can move out of the cavity 7 along with the insert rod 6 when the moving mold 3 and the fixed mold 2 separate, the release agent of the insert rod 6 and the release agent of the cavity 7 can be changed. This ensures that the adsorption force of the insert rod 6 on the bottle body is greater than that of the cavity 7 on the bottle body. Moreover, since the opening end of the bottle body is in contact with the push plate 12, and there is no release agent on the push plate 12, the push plate 12 can also provide a certain adsorption force on the bottle body, thereby ensuring that the insert rod 6 moves out of the cavity 7 with the bottle body.

[0041] like Figure 1-Figure 5As shown, in a preferred embodiment of the present invention, the spraying assembly includes a spraying component 15 and an infusion tube 32. There are multiple spraying components 15, each of which is fixedly installed on a fixing plate 14 and sleeved on a plug rod 6. Each spraying component 15 is connected to an external infusion device through the infusion tube 32. The inner wall of the spraying component 15 is connected to multiple circumferentially arranged nozzles, which face the outer circular surface of the plug rod 6.

[0042] In one embodiment of this invention, it should be noted that the external infusion device of the present invention includes a storage tank, a pump, a regulating valve, etc. All of the above components are existing technologies, and the present invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of the present invention.

[0043] In practical applications, this embodiment uses nozzles arranged in a circular pattern to spray the release agent onto the outer surface of each insert 6, avoiding the problem of difficulty in applying the release agent to the middle insert 6 due to obstruction from the outer insert 6 in manual application.

[0044] like Figures 1-6 As shown, in a preferred embodiment of the present invention, the application assembly includes a sleeve 16, an annular brush 17, a side plate 19, a drive wheel 20, and a synchronization assembly. Each insertion rod 6 has a corresponding sleeve 16. The sleeve 16 is rotatably mounted on the push plate 12. An annular brush 17 is embedded in each sleeve 16. The annular brush 17 is in contact with the insertion rod 6 and is slidably connected to the insertion rod 6. Two adjacent sleeves 16 at the same horizontal height are connected by a first synchronous belt 18. The side plate 19 is fixedly mounted on the push plate 12. Multiple drive wheels 20 are rotatably mounted on the side plate 19. Two adjacent drive wheels 20 are connected by a second synchronous belt 21. Sleeves 16 at different horizontal heights are connected to the drive wheels 20 by a third synchronous belt 28. One drive wheel 20 is driven to rotate by the synchronization assembly.

[0045] Specifically, the synchronization assembly includes a transmission gear 22, a transmission rod 23, a ratchet assembly 24, and a rack plate 25. The transmission gear 22 and the transmission rod 23 are both rotatably mounted on the side plate 19, and the transmission gear 22 is sleeved on the transmission rod 23. The transmission gear 22 is connected to the transmission rod 23 through the ratchet assembly 24. The rack plate 25 is fixedly mounted on the moving mold 3 and meshes with the transmission gear 22. The transmission rod 23 is connected to the drive wheel 20 through the transmission assembly. When the electric cylinder 13 extends and drives the push plate 12 away from the moving mold 3, the rack plate 25 causes the transmission gear 22 to rotate. At this time, the ratchet assembly 24 keeps the transmission rod 23 stationary. When the electric cylinder 13 retracts and drives the push plate 12 closer to the moving mold 3, the rack plate 25 causes the transmission gear 22 to rotate. At this time, the ratchet assembly 24 causes the transmission rod 23 and the transmission gear 22 to rotate synchronously.

[0046] Specifically, the transmission assembly includes a first bevel gear 26 and a second bevel gear 27. Both the first bevel gear 26 and the second bevel gear 27 are rotatably mounted in the side plate 19. The first bevel gear 26 meshes with the second bevel gear 27, and their axes are perpendicular. The first bevel gear 26 is coaxially and fixedly connected to the transmission rod 23, and the second bevel gear 27 is coaxially and fixedly connected to the drive wheel 20.

[0047] In one embodiment of this invention, it should be noted that the ratchet assembly 24 of the present invention includes a pawl, an outer ratchet, a fixed connector, etc. All of the above components are prior art, and the present invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical structure and circuit structure, and this does not affect the integrity of the present invention.

[0048] In practical application, when the push plate 12 approaches the moving mold 3, the spraying assembly sprays the release agent onto the outer surface of the insert rod 6. During the movement of the push plate 12, the annular brush 17 embedded in the sleeve 16 adheres to the outer surface of the insert rod 6, and each sleeve 16 can rotate. When the rotating sleeve 16 contacts the release agent, it spreads the release agent that was originally sprayed onto the outer surface of the insert rod 6 evenly, forming a thin layer of release agent on the outer surface of the insert rod 6. The process of driving each sleeve 16 to rotate is as follows: When the push plate 12 approaches the moving mold 3, under the action of the rack plate 25, the transmission gear 22 will rotate, and the transmission gear 22 will drive the transmission rod 23 to rotate through the ratchet assembly 24. The transmission rod 23 drives the first bevel gear 26 to rotate synchronously, and the first bevel gear 26 causes the second bevel gear 27 and a drive wheel 20 to rotate synchronously. Because the two adjacent drive wheels 20 are connected by the second synchronous belt 21, therefore... Figure 5Taking the example shown, all drive wheels 20 will rotate synchronously, and the drive wheels 20 will drive a sleeve 16 to rotate synchronously through the third synchronous belt 28. Two adjacent sleeves 16 at the same horizontal height are connected by the first synchronous belt 18, which means that all sleeves 16 will rotate synchronously, thereby realizing that all annular brushes 17 rotate at the same time. With the movement of the push plate 12, the annular brushes 17 rotate when they move, thereby evenly applying the release agent to the insert rod 6, improving the efficiency of the preparation process before injection molding of cosmetic bottles. When the push plate 12 moves away from the moving mold 3 to push the bottle body out, the transmission gear 22 rotates and the transmission rod 23 stops through the ratchet assembly 24, so the annular brushes 17 will not rotate, avoiding aggravating the wear of the annular brushes 17.

[0049] like Figures 1-7 As shown, in a preferred embodiment of the present invention, the top of the fixed mold 2 is connected to 9 and the circulation outlet 10, and a cooling channel 11 is provided inside the fixed mold 2. The two ends of the cooling channel 11 are connected to 9 and the circulation outlet 10 respectively, and the 9 and the circulation outlet 10 are connected to an external cooling circulation assembly.

[0050] In one embodiment of this invention, it should be noted that the external cooling circulation assembly of the present invention includes a heat exchanger, an electric pump, an electronic regulating valve, etc. All of the above components are prior art, and the present invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of the present invention.

[0051] In practical application, this embodiment takes into account that the natural cooling time of the raw material injected into the cavity 7 will increase the processing time if it is too long. Therefore, the fixed mold 2 is provided with a 9 connected to the external cooling circulation component, a circulation outlet 10 and a cooling channel 11. The cooling medium is injected through the 9, circulates inside the fixed mold 2 through the cooling channel 11, and flows out from the circulation outlet 10. In this way, the cooling medium accelerates the heat exchange with the high temperature raw material in the cavity 7, thereby shortening the cooling time.

[0052] like Figures 1-8 As shown, in a preferred embodiment of the present invention, the base 1 has a discharge port 29, and a discharge plate 30 is slidably installed in the discharge port 29. The discharge plate 30 is driven by an output source to move up and down. The base 1 has a discharge cavity 31, which is connected to the discharge port 29. The discharge port 29 faces the inlet end of the discharge cavity 31. The horizontal height of the inlet end of the discharge cavity 31 is higher than the horizontal height of the outlet end of the discharge cavity 31, and the inlet end of the discharge cavity 31 is close to the discharge port 29. When the hydraulic rod 4 retracts to separate the moving mold 3 from the fixed mold 2, the electric cylinder 13 extends to move the push plate 12 away from the moving mold 3. At this time, the push plate 12 moves away from the insert rod 6, and the output source drives the discharge plate 30 to rise and discharge the bottle on the push plate 12 to the discharge port 29.

[0053] In one embodiment, the output source may be a motor-driven threaded rod assembly, an electric telescopic rod, or other components capable of lifting and lowering. This embodiment does not impose any specific limitations on these components.

[0054] In practical application, considering that the pusher plate 12 is in contact with the bottle opening, it may cause the bottle to remain attached to the pusher plate 12 even after the pusher plate 12 pushes the bottle away from the insert rod 6. Therefore, when the hydraulic rod 4 retracts to separate the moving mold 3 from the fixed mold 2, the electric cylinder 13 extends to move the pusher plate 12 away from the moving mold 3. At this time, the pusher plate 12 moves the bottle away from the insert rod 6, and the bottle is located on the discharge port 29. Then, the output source drives the discharge plate 30 to rise. The top of the discharge plate 30 rises while adhering to the pusher plate 12, thereby scraping the bottle off the pusher plate 12 and thus removing the bottle from the pusher plate 12. The bottle body on plate 12 is fed to the feeding port 29. Although the feeding plate 30 will cause slight wear at the opening of the bottle body during this process, the opening of the bottle body needs to be polished and other treatments afterward to match the bottle cap. Therefore, the slight wear at the opening of the bottle body caused by feeding will not affect the processing quality. The bottle body falling into the feeding port 29 will fall onto the discharge chamber 31. The feeding end of the discharge chamber 31 is close to the feeding port 29 to prevent the bottle body from being broken due to excessive drop. Then the bottle body rolls out of the base 1 with the inclined plate surface of the discharge chamber 31, thus completing the feeding and collection of the bottle body.

[0055] Please see Figures 1-8 As shown, the present invention provides a method for using an injection mold for processing cosmetic bottles. The method is applied to an injection mold for processing cosmetic bottles as described in the above embodiment, and includes the following steps:

[0056] Step S1: First, ensure that the moving mold 3 and the fixed mold 2 are in the mold separation state. Drive the push plate 12 away from the moving mold 3 through the electric cylinder 13, so that the push plate 12 slides to the end of the insert rod 6 away from the moving mold 3.

[0057] Step S2: Subsequently, as the electric cylinder 13 retracts and drives the push plate 12 to approach the moving mold 3, the release agent is sprayed onto the outer surface of each insert rod 6 through the spraying component. At the same time, the coating component spreads the release agent sprayed on the outer surface of the insert rod 6 evenly, and the release agent is manually sprayed into the cavity 7.

[0058] Step S3: Immediately afterwards, the hydraulic rod 4 extends to close the moving mold 3 and the fixed mold 2, so that the push plate 12 closes with the fixed mold 2, and the insert rod 6 is inserted into the cavity 7;

[0059] Step S4: The external injection molding equipment injects the raw material into the cavity 7 through the injection port 8. At this time, the raw material wraps around the insert 6 and fills the cavity 7. Wait for a period of time for the bottle to be formed.

[0060] Step S5: The moving mold 3 and the fixed mold 2 are separated by the hydraulic rod 4. The bottle body is sleeved on the insert rod 6 and moved out of the cavity 7. Then, step S1 is repeated. The push plate 12 slides to the end of the insert rod 6 away from the moving mold 3. During this process, the bottle body will be pushed away from the insert rod 6, thereby completing the operation of unloading all the bottles.

[0061] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

8. A method of using an injection mold for processing cosmetic bottles, characterized in that, The method is applied to an injection mold for processing cosmetic bottles as described in any one of claims 1-7, and the method includes the following steps: Step S1: First, ensure that the moving mold (3) and the fixed mold (2) are in the mold separation state. Drive the push plate (12) away from the moving mold (3) through the electric cylinder (13) and let the push plate (12) slide to the end of the insert rod (6) away from the moving mold (3). Step S2: Subsequently, during the process of the electric cylinder (13) retracting and driving the push plate (12) to approach the moving mold (3), the release agent is sprayed onto the outer surface of each insert (6) by the spraying component, and at the same time, the coating component spreads the release agent sprayed on the outer surface of the insert (6) evenly, and the release agent is manually sprayed into the cavity (7). Step S3: Immediately afterwards, the hydraulic rod (4) extends to close the moving mold (3) and the fixed mold (2), so that the push plate (12) closes with the fixed mold (2), and the insert rod (6) is inserted into the cavity (7); Step S4: The external injection molding equipment injects the raw material into the cavity (7) through the injection port (8). At this time, the raw material wraps around the insert (6) and fills the cavity (7). Wait for a period of time for the bottle to be formed. Step S5: The moving mold (3) and the fixed mold (2) are separated by the hydraulic rod (4). The bottle body is sleeved on the insert rod (6) and moves out of the cavity (7). Then, step S1 is repeated. The push plate (12) slides to the end of the insert rod (6) away from the moving mold (3).
