Description

Technical Field

[0001] This application relates to the technical field of vertical injection molding machine equipment, and in particular to a linear slide rail type vertical injection molding machine sliding mold mechanism and a vertical injection molding machine. Background Technology

[0002] Vertical injection molding machines are widely used in plastic product manufacturing due to their small footprint and ease of operation. Traditional vertical injection molding machine sliding mold mechanisms often employ a rotary design, using rotation to switch molds. However, rotary sliding mold mechanisms are prone to vibration and positioning deviations under high-speed motion or high-load conditions, affecting injection molding accuracy and stability. In recent years, with increasing demands for precision in injection molded products, developing more stable and accurate sliding mold mechanisms has become an urgent industry need.

[0003] Currently, the main sliding mold mechanism of vertical injection molding machines is the rotary sliding mold mechanism, which achieves mold switching through a rotating platform. During the rotation process, vibration is easily generated, affecting the positioning accuracy of the mold. Summary of the Invention

[0004] To address the issue of low mold positioning accuracy in existing vertical injection molding machines, this application provides a linear slide rail type sliding mold mechanism for a vertical injection molding machine and a vertical injection molding machine.

[0005] Firstly, the linear slide rail type vertical injection molding machine sliding mechanism provided in this application adopts the following technical solution: A linear guide rail type sliding mold mechanism for a vertical injection molding machine includes: The base is horizontally positioned. A linear guide rail is disposed on one side of the base along the width direction of the base, the slide rail of the linear guide rail is connected to the base, and one end of the linear guide rail protrudes from the base; A sliding template is disposed on the side of the linear guide rail away from the base and is connected to the slider of the linear guide rail; A sliding mold drive cylinder is fixedly connected to the base, and the piston rod of the sliding mold drive cylinder is connected to the sliding plate to drive the sliding plate to reciprocate along the linear guide when the piston rod moves.

[0006] By adopting the above technical solution, the base provides a stable mounting platform for the entire sliding mold mechanism, ensuring the stability of the positions of other components such as linear guides and sliding mold drive cylinders. Simultaneously, the base serves as a transitional component connecting to the injection molding machine frame. The linear guides provide linear motion guidance and bear the weight of the sliding platen and mold. One end of the linear guide protruding from the base reserves space for the ejection station, enabling separation of the injection station and the part removal station. The sliding platen can support the mold and drive its movement via the linear guides, allowing the mold to move between the injection station and the part removal station. The sliding mold drive cylinder provides the driving force for the reciprocating motion of the sliding platen, directly pushing the sliding platen along the linear guides via the piston rod to achieve mold switching. By using linear guides, the traditional motion mode can be changed from rotation to linear sliding, eliminating the inherent centrifugal force and unbalanced torque of rotational motion, avoiding the impact of gear backlash and / or shaft wear on positioning accuracy, and improving the problem of low mold positioning accuracy in existing vertical injection molding machines.

[0007] Preferably, the linear guide is a heavy-duty ball bearing guide, and the rated dynamic load of the linear guide is 50kN~120kN.

[0008] By adopting the above technical solution, the linear guide rail using ball bearings as rolling elements has a high load-bearing capacity and is suitable for heavy-duty working conditions. It can provide sufficient load-bearing capacity to ensure that the guide rail does not deform or fail when bearing the weight of the mold and the injection pressure. The heavy-duty guide rail has a larger guide rail and slider cross section and higher rigidity, and has a strong ability to resist external deformation. Compared with the rotary shaft system, which is prone to elastic deformation and vibration, the high rigidity of the heavy-duty guide rail can suppress vibration from the source, thereby improving positioning accuracy and solving the problem of low positioning accuracy of existing vertical injection molding machine molds.

[0009] Preferably, the sliding mold drive cylinder is a double-acting cylinder, and the cylinder diameter of the sliding mold drive cylinder is 100mm~160mm.

[0010] By adopting the above technical solution, the sliding mold drive cylinder can provide bidirectional active driving force, enabling the sliding mold plate to move into the injection molding station and the part removal station without relying on external force or spring reset. Compared with the rotary shaft system that requires a deceleration mechanism, the transmission efficiency is higher.

[0011] Preferably, it also includes a corrugated rubber sheet, which covers the linear guide rail and is connected to the sliding plate. The corrugated rubber sheet is used to prevent external impurities from entering the linear guide rail.

[0012] By adopting the above technical solution, the corrugated rubber sheet is a rubber sheet with a corrugated surface, which has a certain degree of elasticity and extensibility. The corrugated rubber sheet covers the exposed part of the linear guide rail, which can physically isolate external impurities such as dust, debris and / or coolant from falling into the rolling surface of the linear guide rail. There is no need to frequently clean the dust and debris on the guide rail, avoiding failure of the linear guide rail caused by the external environment, reducing manual maintenance costs, reducing downtime, and ensuring the stable operation of the linear guide rail.

[0013] Secondly, this application provides a vertical injection molding machine, which adopts the following technical solution: A vertical injection molding machine, comprising: The machine includes a frame, and a mold clamping assembly and an injection molding assembly mounted on the frame. The mold clamping assembly includes a mold locking guide post, a mold locking hydraulic cylinder, and a mold locking plate. The mold locking guide post is movably inserted into a through hole reserved in the base. The mold locking hydraulic cylinder is located on the side of the base away from the linear guide rail. The piston rod of the mold locking hydraulic cylinder is connected to the mold locking guide post. The mold locking plate is connected to the end of the mold locking guide post away from the mold locking hydraulic cylinder. The mold locking plate is opposite to the sliding plate. The injection molding assembly includes an injection lower extension cylinder, an injection frame, an injection cylinder, and an injection drive motor. The cylinder barrel of the injection lower extension cylinder is connected to the mold locking plate. The piston rod of the injection lower extension cylinder is connected to the injection frame. The injection cylinder is connected to the injection frame. The injection drive motor is used to drive the injection cylinder to perform injection operations. A linear guide rail type vertical injection molding machine sliding mold mechanism is provided, wherein the linear guide rail type vertical injection molding machine sliding mold mechanism is connected to the machine frame; the linear guide rail type vertical injection molding machine sliding mold mechanism is used to drive the sliding plate to move between the injection position and the part removal position.

[0014] By adopting the above technical solutions, the frame can support other components, serving as the installation foundation for the entire machine. The mold closing assembly enables the mold to close or open. The mold locking guide pillars transmit the mold locking force, guiding the lifting and lowering movement of the mold locking platen to ensure the accuracy of the mold closing direction. The mold locking hydraulic cylinder provides the power for mold closing and opening, generating mold locking force through hydraulic pressure to overcome injection pressure. The mold locking platen supports the upper mold and is lifted and lowered under the drive of the mold locking hydraulic cylinder to achieve mold closing and opening. The injection assembly can perform injection molding on the closed mold. The injection lower extension cylinder drives the injection frame to rise and fall, allowing the injection cylinder to extend into the mold injection cavity when needed for injection molding. After completion and reset, the injection frame, serving as the mounting carrier for the injection cylinder, transmits the movement of the injection cylinder to the injection cylinder. The injection cylinder can hold molten plastic and guide it into the mold cavity. The injection drive motor can drive the spiral push rod to rotate, melting the plastic and injecting it into the mold cavity. The sliding mold mechanism of the linear guide vertical injection molding machine can realize mold switching. During injection, it moves into the mold closing position, and after injection, it moves out to the part removal position, separating the ejection and part removal operations from the injection operation in space. The mold closing assembly shares a base with the sliding mold mechanism of the linear guide vertical injection molding machine, achieving unified reference, reducing cumulative errors, and improving mold closing accuracy.

[0015] Preferably, the mold-locking hydraulic cylinder is arranged vertically downwards, the piston rod of the mold-locking hydraulic cylinder is fixedly connected to at least four mold-locking guide columns, the mold-locking guide columns extend in a vertical direction, and the mold-locking plate is connected to the end of the mold-locking guide column away from the mold-locking hydraulic cylinder and is located above the mold-locking hydraulic cylinder.

[0016] By adopting the above technical solution, the four guide columns are symmetrically arranged, and the hydraulic cylinder piston rod can drive the four guide columns simultaneously through the connecting frame, so that the clamping force is evenly transmitted to the four corners of the clamping plate. The clamping plate can ensure that the clamping force is evenly distributed, and the clamping plate will not tilt or bend after being subjected to force, thus avoiding defects such as flash and / or overflow caused by plate deformation.

[0017] Preferably, an injection guide post is also fixedly provided on the locking template, and a guide sleeve hole is provided on the injection frame to slide with the injection guide post. The injection guide post passes through the guide sleeve hole and is used to guide the injection frame to rise and fall stably.

[0018] By adopting the above technical solution, the injection guide post can provide a guiding reference for the lifting and lowering of the injection frame, ensuring the relative position of the injection frame and the locking platen. The guide sleeve hole and the guide post form a sliding fit, restricting the radial degree of freedom of the injection frame and retaining only the axial degree of freedom, so that the injection frame can slide smoothly along the guide post, ensuring that the injection barrel remains vertical during the lifting and lowering process, and ensuring that the injection nozzle is accurately aligned with the injection cavity of the mold.

[0019] Preferably, the injection molding assembly further includes a plastic feed hopper, which is connected to the injection cylinder.

[0020] By adopting the above technical solution, the plastic feed hopper can serve as a temporary storage container for raw materials, ensuring that the injection barrel can continuously receive raw material supply during continuous operation, establishing a raw material supply channel, so that plastic particles can smoothly enter the injection barrel, plasticize and melt under heating, and avoid defects in injection molded products caused by fluctuations in material supply.

[0021] Preferably, it also includes an ejector assembly, which is connected to the frame and is disposed at one end of the linear guide rail protruding from the base. The ejector assembly is used to eject the finished product from the sliding template.

[0022] By adopting the above technical solution, the ejection component can separate the product from the mold, so that the product can be taken out or automatically dropped, completing a production cycle.

[0023] Preferably, the ejection assembly is an ejection cylinder, the piston rod of which passes through a pre-drilled hole in the frame and corresponds to the position of one end of the linear guide rail protruding from the base.

[0024] By adopting the above technical solutions, the ejection cylinder can shorten the ejection time and speed up the production cycle. The cost of the cylinder and pneumatic components is much lower than that of hydraulic systems and servo electric systems, reducing the overall manufacturing and maintenance costs. The cylinder itself has a simple structure and does not require a complex hydraulic station or servo controller, resulting in high reliability and a low failure rate.

[0025] Preferably, the vertical injection molding machine satisfies at least one of the following: the linear guide is a roller linear guide; the sliding mold drive cylinder is an electric push rod; auxiliary support wheels are also provided on both sides of the sliding plate, and the auxiliary support wheels are in rolling contact with the base; a chip collection box is provided below the corrugated rubber plate.

[0026] By adopting the above technical solutions, the linear guide is a roller linear guide, which can be set according to the actual situation to facilitate matching molds of different weights or sizes. The sliding mold drive cylinder is an electric push rod, which is more energy-efficient, cleaner and quieter. The auxiliary support wheel can share part of the weight of the sliding plate and the mold, reducing the load on the linear guide. The chip collection box can collect plastic flash or waste materials falling from the mold, ensuring the stability of the linear guide's operation.

[0027] Preferably, the vertical injection molding machine is configured as follows: the sliding platen is moved to a mold-closing position opposite to the locking platen by the sliding mold mechanism of the linear guide vertical injection molding machine; when the sliding platen is in the mold-closing position, the locking platen and the sliding platen are closed by the mold-closing assembly to form a cavity; molten plastic is injected into the cavity by the injection assembly; after the molten plastic forms a molded product in the cavity, the locking platen and the sliding platen are separated by the mold-closing assembly; the sliding platen is moved to the part-removal position by the sliding mold mechanism of the linear guide vertical injection molding machine, and the molded product is ejected by the ejection assembly.

[0028] By adopting the above technical solution, the vertical injection molding machine can send the lower mold into the mold closing area through the linear slide rail vertical injection molding machine sliding mold mechanism, close the upper and lower molds through the mold closing mechanism to form a closed cavity, inject molten plastic into the cavity through the injection molding mechanism to form the product, then open the mold through the mold closing mechanism, and finally move the lower mold out to the part removal area through the sliding mold mechanism, and eject the product through the ejector component to complete the injection molding process.

[0029] In summary, this application includes at least one of the following beneficial technical effects: The base provides a stable mounting platform for the entire sliding mold mechanism, ensuring the stability of the positions of other components such as linear guides and sliding mold drive cylinders. Simultaneously, the base serves as a transitional component connecting to the injection molding machine frame. The linear guides provide linear motion guidance and bear the weight of the sliding platen and mold. One end of the linear guide protruding from the base provides space for the ejection station, enabling separation of the injection station and the part removal station. The sliding platen carries the mold and drives its movement via the linear guides, allowing the mold to move between the injection station and the part removal station. The sliding mold drive cylinder provides the driving force for the reciprocating motion of the sliding platen, directly pushing the sliding platen along the linear guides via the piston rod to achieve mold switching. By using linear guides, the traditional motion mode is changed from rotation to linear sliding, eliminating the inherent centrifugal force and unbalanced torque of rotational motion, avoiding the impact of gear backlash and / or shaft wear on positioning accuracy, and improving the problem of low mold positioning accuracy in existing vertical injection molding machines. The frame supports other components, serving as the mounting base for the entire machine. The mold closing assembly enables the mold to close or open. The mold locking guide pillars transmit the mold locking force, guiding the lifting and lowering movement of the mold locking platen to ensure the accuracy of the mold closing direction. The mold locking hydraulic cylinder provides the power for mold closing and opening, generating mold locking force through hydraulic pressure to overcome injection pressure. The mold locking platen supports the upper mold and is raised and lowered under the drive of the mold locking hydraulic cylinder to achieve mold closing and opening. The injection assembly performs injection molding on the closed mold. The injection lower extension cylinder drives the injection frame to rise and fall, allowing the injection cylinder to extend into the mold injection cavity when needed and reset after injection. The injection frame, serving as the mounting carrier for the injection cylinder, transmits the movement of the injection cylinder to the injection cylinder. The injection cylinder can hold molten plastic and guide it into the mold cavity. The injection drive motor can drive the spiral push rod to rotate, melting the plastic and injecting it into the mold cavity. The sliding mold mechanism of the linear slide rail vertical injection molding machine can realize mold switching. During injection, it moves into the mold closing position, and after injection, it moves out to the part removal position, thus separating the ejection and part removal operations from the injection operation in space. The mold closing assembly shares a base with the sliding mold mechanism of the linear slide rail vertical injection molding machine, achieving unified reference, reducing cumulative errors, and improving mold closing accuracy. A vertical injection molding machine can send the lower mold into the mold closing area through a linear slide rail vertical injection molding machine sliding mechanism. The mold closing mechanism closes the upper and lower molds to form a closed cavity. The injection molding mechanism injects molten plastic into the cavity to form the product. Then, the mold closing mechanism opens the mold. Finally, the sliding mechanism moves the lower mold out to the part removal area, and the ejector assembly ejects the product, completing the injection molding process. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 This application will be described in further detail.

[0033] This application discloses a linear slide rail type sliding mold mechanism 1 for a vertical injection molding machine. (Refer to...) Figure 1 and Figure 2 The linear guide rail type vertical injection molding machine sliding mold mechanism 1 includes a base 11, a linear guide rail 12, a sliding plate 13, and a sliding mold drive cylinder 14.

[0034] like Figure 1 and Figure 2 As shown, the base 11 is horizontally positioned, and the linear guide rail 12 is positioned on one side of the base 11 along its width. The slide rail of the linear guide rail 12 is connected to the base 11, and one end of the linear guide rail 12 protrudes from the base 11. The sliding plate 13 is positioned on the side of the linear guide rail 12 away from the base 11 and is connected to the slider of the linear guide rail 12. The sliding mold drive cylinder 14 is fixedly connected to the base 11, and the piston rod of the sliding mold drive cylinder 14 is connected to the sliding plate 13 to drive the sliding plate 13 to reciprocate along the linear guide rail 12 when the piston rod moves. The base 11 provides a stable mounting platform for the entire sliding mold mechanism, ensuring the stability of the positions of other components such as the linear guide rail 12 and the sliding mold drive cylinder 14. At the same time, the base 11 can also serve as a transition component for connecting to the injection molding machine frame 2. The linear guide rail 12 provides a stable mounting platform for the entire sliding mold mechanism, ensuring the stability of the positions of other components such as the linear guide rail 12 and the sliding mold drive cylinder 14. The linear guide 12 provides linear motion guidance and supports the weight of the sliding platen 13 and the mold. One end of the linear guide 12 protruding from the base 11 reserves space for the ejection station to separate the injection station and the part removal station. The sliding platen 13 can support the mold and drive the mold to move through the linear guide 12, realizing the movement of the mold between the injection station and the part removal station. The sliding platen drive cylinder 14 can provide the driving force for the reciprocating motion of the sliding platen 13. The piston rod directly pushes the sliding platen 13 to slide along the linear guide 12 to realize mold switching. By using the linear guide 12, the traditional motion mode can be changed from rotation to linear sliding, eliminating the centrifugal force and unbalanced torque inherent in rotational motion, avoiding the impact of gear backlash and / or shaft wear on positioning accuracy, and improving the problem of low positioning accuracy of existing vertical injection molding machines.

[0035] For example, in this embodiment, the linear guide 12 is a heavy-duty ball bearing guide. The rated dynamic load of the linear guide 12 is 50kN~120kN. The linear guide 12, which uses balls as rolling elements, has a high load-bearing capacity and is suitable for heavy-duty working conditions. It can provide sufficient load-bearing capacity to ensure that the guide does not deform or fail when bearing the weight of the mold and the injection pressure. The heavy-duty guide has a larger guide and slider cross-section and higher rigidity, and has a strong ability to resist external deformation. Compared with the turntable type, which is prone to elastic deformation and vibration, the heavy-duty guide has a larger guide and slider cross-section and higher rigidity. The rotating shaft system, with its heavy-duty guide rails exhibiting high rigidity, can suppress vibration at the source, thereby improving positioning accuracy and addressing the issue of low positioning accuracy in existing vertical injection molding machines. The sliding mold drive cylinder 14 is a double-acting cylinder with a cylinder diameter of 100mm~160mm. The sliding mold drive cylinder 14 can provide bidirectional active driving force, enabling the sliding plate 13 to move into the injection station and part removal station without relying on external force or spring reset. Compared to the rotary shaft system that requires a deceleration mechanism, it has higher transmission efficiency.

[0036] It should be noted that, in this embodiment of the application, the linear guide vertical injection molding machine sliding mold mechanism 1 also includes a corrugated rubber plate 15. The corrugated rubber plate 15 covers the top of the linear guide 12 and is connected to the sliding plate 13. The corrugated rubber plate 15 is used to block external impurities from entering the linear guide 12. The corrugated rubber plate 15 is a rubber sheet with a corrugated surface, which has a certain elasticity and extensibility. The corrugated rubber plate 15 covers the exposed part of the linear guide 12, which can physically isolate external impurities such as dust, debris and / or coolant from falling into the rolling surface of the linear guide 12. It eliminates the need for frequent cleaning of dust and debris on the guide, avoids failure of the linear guide 12 due to the external environment, reduces manual maintenance costs, reduces downtime, and ensures the stable operation of the linear guide 12.

[0037] This application also discloses a vertical injection molding machine. (Refer to...) Figure 3 The vertical injection molding machine includes a frame 2, a mold clamping assembly 3, an injection assembly 4, a linear slide rail vertical injection molding machine sliding mold mechanism 1, and an ejection assembly 5.

[0038] like Figure 2 and Figure 4As shown, the mold closing assembly 3 is mounted above the frame 2. The mold closing assembly 3 includes a mold locking guide post 31, a mold locking hydraulic cylinder 32, and a mold locking plate 33. The mold locking guide post 31 is movably inserted into the through hole reserved in the base 11. The mold locking hydraulic cylinder 32 is located on the side of the base 11 away from the linear guide rail 12. The piston rod of the mold locking hydraulic cylinder 32 is connected to the mold locking guide post 31. The mold locking plate 33 is connected to the end of the mold locking guide post 31 away from the mold locking hydraulic cylinder 32. The mold locking plate 33 is arranged opposite to the sliding plate 13. The frame 2 can support other components and serve as the installation base for the whole machine. The mold closing assembly 3 can close or open the mold. The mold locking guide post 31 can transmit the mold locking force and guide the lifting and lowering movement of the mold locking plate 33 to ensure the accuracy of the mold closing direction. The mold locking hydraulic cylinder 32 can provide the power for mold closing and opening. The mold locking force generated by hydraulic pressure overcomes the injection pressure. The mold locking plate 33 can support the upper mold and is lifted and lowered under the drive of the mold locking hydraulic cylinder 32 to realize the closing and opening of the mold.

[0039] In this embodiment, the clamping hydraulic cylinder 32 is vertically downward. The piston rod of the clamping hydraulic cylinder 32 is fixedly connected to at least four clamping guide pillars 31 through a metal plate. The clamping guide pillars 31 extend vertically. The clamping template 33 is connected to the end of the clamping guide pillar 31 away from the clamping hydraulic cylinder 32 and is located above the clamping hydraulic cylinder 32. The four guide pillars are symmetrically arranged. The piston rod of the hydraulic cylinder can drive the four guide pillars simultaneously through the connecting frame, so that the clamping force is evenly transmitted to the four corners of the clamping template 33. The clamping template 33 can ensure that the clamping force is evenly distributed. The clamping template 33 will not tilt or bend after being subjected to force, avoiding defects such as flash and / or overflow caused by template deformation.

[0040] like Figure 2 and Figure 5 As shown, the injection molding assembly 4 includes an injection cylinder 41, an injection frame 42, an injection barrel 43, and an injection drive motor 44. The cylinder of the injection cylinder 41 is connected to the locking platen 33, the piston rod of the injection cylinder 41 is connected to the injection frame 42, and the injection barrel 43 is connected to the injection frame 42. The injection drive motor 44 is used to drive the injection barrel 43 to perform injection operations. The injection molding assembly 4 can perform injection molding on a closed mold. The injection cylinder 41 can drive the injection frame 42 to rise and fall, so that the injection barrel 43 can extend into the injection cavity of the mold when needed and reset after injection. The injection frame 42 serves as the mounting carrier for the injection barrel 43, transmitting the movement of the injection cylinder 41 to the injection barrel 43. The injection barrel 43 can contain molten plastic and guide the plastic into the mold cavity. The injection drive motor 44 can drive the spiral push rod to rotate, melting the plastic and injecting it into the mold cavity.

[0041] In this embodiment, the injection molding component 4 also includes a plastic feed hopper 46, which is connected to the injection barrel 43. The plastic feed hopper 46 can serve as a temporary storage container for raw materials, ensuring that the injection barrel 43 can continuously receive raw material supply during continuous operation, establishing a raw material supply channel, so that plastic particles can smoothly enter the injection barrel 43, plasticize and melt under heating, and avoid defects in injection molded products caused by fluctuations in material supply.

[0042] like Figure 1 and Figure 3 As shown, the sliding mold mechanism 1 of the linear slide rail vertical injection molding machine is connected to the frame 2, specifically, the bottom surface of the base 11 is connected to the top surface of the frame 2. The sliding mold mechanism 1 of the linear slide rail vertical injection molding machine is used to drive the sliding plate 13 to move between the injection position and the part removal position. The sliding mold mechanism 1 of the linear slide rail vertical injection molding machine can realize mold switching. During injection, it moves into the mold closing position, and after injection, it moves out to the part removal position, so that the ejection and part removal operations are separated from the injection operation in space. The mold closing assembly 3 and the sliding mold mechanism 1 of the linear slide rail vertical injection molding machine share the base 11, which realizes the standardization of the reference, reduces the cumulative error, and improves the mold closing accuracy.

[0043] For example, an injection guide post 45 is also fixedly provided on the locking template 33, and a guide sleeve hole is provided on the injection frame 42 that slides with the injection guide post 45. The injection guide post 45 passes through the guide sleeve hole and is used to guide the injection frame 42 to rise and fall stably. The injection guide post 45 can provide a guiding reference for the rise and fall of the injection frame 42, ensuring the relative position of the injection frame 42 and the locking template 33. The guide sleeve hole and the guide post form a sliding fit, restricting the radial degree of freedom of the injection frame 42 and retaining only the axial degree of freedom, so that the injection frame 42 can slide smoothly along the guide post, ensuring that the injection cylinder 43 always remains vertical during the rise and fall process, and ensuring that the injection nozzle is accurately aligned with the injection cavity of the mold.

[0044] like Figure 5 As shown, the ejector assembly 5 is connected to the frame 2. The ejector assembly 5 is located at one end of the linear guide rail 12 protruding from the base 11. The ejector assembly 5 is used to eject the finished product from the sliding template 13. The ejector assembly 5 is a single ejector cylinder. The piston rod of the ejector cylinder passes through the reserved through hole in the frame 2 and corresponds to the position of one end of the linear guide rail 12 protruding from the base 11. The ejector assembly 5 can realize the separation of the product from the mold, so that the product can be taken out or automatically dropped to complete a production cycle. The ejector cylinder can shorten the ejection time and speed up the production cycle. The cost of the cylinder and pneumatic components is much lower than that of the hydraulic system and servo electric system, reducing the overall manufacturing cost and maintenance cost. The cylinder itself has a simple structure and does not require a complex hydraulic station or servo controller. It has high reliability and low failure rate.

[0045] It should be noted that, in this embodiment, the vertical injection molding machine satisfies at least one of the following: the linear guide 12 is a roller linear guide 12; the sliding mold drive cylinder 14 is an electric push rod; auxiliary support wheels are also provided on both sides of the sliding plate 13, and the auxiliary support wheels are in rolling contact with the base 11; a chip collection box is provided below the corrugated rubber plate 15; the linear guide 12 is a roller linear guide 12, which can be set according to actual conditions to facilitate matching molds of different weights or sizes; the sliding mold drive cylinder 14 is an electric push rod, which is more energy-efficient, cleaner and quieter; the auxiliary support wheels can share part of the weight of the sliding plate 13 and the mold, reducing the load on the linear guide 12; the chip collection box can collect plastic flash or waste material falling from the mold, ensuring the stability of the linear guide 12.

[0046] For example, in this embodiment of the application, the vertical injection molding machine is configured to: drive the sliding platen 13 to move to the mold closing position opposite to the locking platen 33 via the linear guide vertical injection molding machine sliding platen mechanism 1; when the sliding platen 13 is in the mold closing position, drive the locking platen 33 and the sliding platen 13 to close via the mold closing assembly 3 to form a cavity; inject molten plastic into the cavity via the injection molding assembly 4; after the molten plastic forms a molded product in the cavity, drive the locking platen 33 and the sliding platen 13 to separate via the mold closing assembly 3; drive the sliding platen 13 to move to the part removal position via the linear guide vertical injection molding machine sliding platen mechanism 1, and eject the molded product via the ejection assembly 5.

[0047] Specifically, the vertical injection molding machine can send the lower mold into the mold closing area through the linear slide rail vertical injection molding machine sliding mold mechanism 1, close the upper and lower molds through the mold closing mechanism to form a closed cavity, inject molten plastic into the cavity through the injection molding mechanism to form the product, then open the mold through the mold closing mechanism, and finally move the lower mold out to the part removal area through the sliding mold mechanism, and ejector component 5 ejects the product to complete the injection molding process.

[0048] In another embodiment of this application, the corrugated rubber sheet 15 has a continuous V-shape corrugation, and the two sides of the corrugated rubber sheet 15 have a height difference. When the sliding plate 13 moves to the ejection position, the corrugated rubber sheet 15 is fully flattened, the wrinkles disappear, and the top forms an approximately flat surface, which can enhance the sealing structure and prevent impurities such as plastic flash, debris, or coolant from entering the interior of the linear guide rail 12 from the end of the guide rail. Compared with conventional flat protective covers that can only rely on covering for passive protection, the end seal formed by the active deformation of the corrugated rubber sheet 15 at the end of the stroke realizes dynamic sealing of the end of the guide rail and improves the protection effect.

[0049] For example, as the corrugated rubber sheet 15 is gradually compressed as it moves with the sliding template 13, debris or coolant accumulated in the folds is squeezed out due to the deformation of the corrugated structure, achieving automatic cleaning. Specifically, each time the sliding template 13 moves to its limit position, the compression process of the corrugations is equivalent to squeezing the grooves, like squeezing out blackheads, pushing debris or dust that might have accumulated in the grooves to the top from bottom to top, and then sliding off the inclined top surface or being gently brushed off by the staff with a cloth. The self-cleaning function relies entirely on the deformation of the corrugated rubber sheet 15 itself, without the need for additional cleaning devices or manual intervention. This avoids the failure of the corrugated sheet function due to long-term accumulation of impurities, while reducing the frequency of manual maintenance and alleviating the workload of the staff.

[0050] It should be noted that there is a direct correspondence between the degree of deformation of the corrugated rubber sheet 15 and the position of the sliding plate 13. By visually observing the compression state of the corrugated rubber sheet 15, i.e. whether its corrugations have been flattened, the operator can determine whether the sliding plate 13 has reached the preset limit position. This provides the operator with redundant position confirmation methods and improves the safety and convenience of equipment operation.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
