Description

Technical Field

[0001] This utility model relates to the field of mold component technology, specifically to mold components for injection molding parts processing. Background Technology

[0002] The field of mold component technology focuses on producing injection-molded parts through precise mold design and efficient injection molding processes, ensuring the quality and consistency of the finished products. In injection molding, the mold components, through precise fitting, ensure the uniform flow, shaping, and cooling of the plastic raw material within the mold, resulting in high-quality plastic parts. Using specialized injection mold components ensures stability and consistency in the production process, maximizes production efficiency, reduces scrap rates, and meets the demands for complex structures and fine surface treatments.

[0003] Chinese utility model patent CN219820478U discloses an anti-displacement injection molding part processing mold, which includes "a plurality of connecting ears at the bottom of the lower mold base, a first screw hole on the connecting ear, and a plurality of second screw holes correspondingly on the base". However, in the process of fixing and installing the lower mold base, the first and second screw holes need to be aligned in advance. The alignment process requires multiple adjustments, which is quite complicated. At the same time, additional tools are needed to laboriously screw bolts or screws into the corresponding first and second screw holes to complete the fixing and installation of the lower mold base. The installation process is cumbersome, which makes it inconvenient to disassemble, replace, and clean the mold, increases operating costs, and reduces operating efficiency and user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a mold assembly for injection molding parts processing, so as to solve the problem mentioned in the background art that the screw hole alignment operation is relatively complicated and requires additional tools and laborious screwing of bolts or screws into the corresponding first and second screw holes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold assembly for injection molding parts, including a base, a support frame installed at one end of the top of the base, a hydraulic cylinder installed at one end of the top of the support frame, and a piston rod inserted into the inside of the hydraulic cylinder.

[0006] The piston rod is fitted with an upper mold cover at its bottom, and an injection port is provided at one end of the top of the upper mold cover.

[0007] The bottom of the upper mold cover has a groove, and a sealing ring is fitted inside the groove.

[0008] Support plates are installed at both ends of the top of the base by screws. Support covers are installed at both ends of one side of the support plates by screws. A handle is provided on one side of the support cover. A screw is installed on one side of the handle. A retaining frame is threaded onto the surface of the screw.

[0009] The upper surface of the base has two sliding grooves at the middle of the middle, and the mold body is slidably connected inside the sliding grooves. Several slots are provided at the bottom of both sides of the mold body.

[0010] The beneficial effects of this utility model are as follows: by pushing the handle, the mold body is slid into the inner cavity of the groove until the mold body can no longer be pushed. At this time, the slot automatically aligns with the set position of the slot frame, avoiding complicated screw hole alignment and adjustment operations. Furthermore, by rotating the handle one by one, multiple slot frames can be driven into the inner cavity of the slot, thereby fixing the mold body. There is no need for laborious rotation of bolts or screws, simplifying the installation process, improving the convenience of mold disassembly, replacement, and cleaning, reducing operating costs, and improving operating efficiency and user experience.

[0011] To ensure that one end of the card frame is not obstructed by the support plate, it is horizontally displaced inside the support plate to facilitate subsequent engagement with the card slot:

[0012] The support plate is further configured such that several through slots are provided at both ends, and the internal dimensions of the through slots and the card slots are consistent with the external dimensions of the card frame.

[0013] By adopting the above technical solution, the card frame can slide smoothly along the inner wall of the through groove, thus passing through the support plate and further inserting into the inside of the card slot, thereby engaging with the card slot.

[0014] To enable easy rotation of the handle to move the card frame horizontally, allowing one end to engage with the card slot:

[0015] Further configuration: a rotating groove is provided in the middle of one end of the support plate near the through groove, one end of the screw is rotatably installed inside the rotating groove, and the other end of the screw is rotatably installed on one side of the inner wall of the support cover, and the clamping frame forms a transmission structure with the screw and the throttle.

[0016] By adopting the above technical solution, rotating the throttle drives the screw to rotate. At this time, the surface of the clamping frame is restricted by the through groove and will not rotate along the screw. Then, by using the thread transmission force, the clamping frame is moved along the surface of the screw until one end gradually passes through the through groove and is embedded in the inner cavity of the clamping slot, thus engaging with the clamping slot. This limits and locks the mold body, avoiding the laborious operation of rotating bolts or screws.

[0017] To enable the mold body to be removed from the base by pushing or pulling on one side:

[0018] A further configuration is provided: a handle is installed on one side of the mold body, and the mold body forms a pull-out structure with the slide groove through the handle.

[0019] By adopting the above technical solution, the bottom of the mold body can be moved along the inner wall of the groove by pushing and pulling the handle on one side of the mold body. This allows the mold body to be quickly removed and placed, and the slots on both sides of the bottom of the mold body can be easily aligned with the frame, avoiding the laborious operation of aligning the first and second screw holes.

[0020] To enable the upper mold cover to reciprocate up and down via an external oil pump for mold closing and demolding operations:

[0021] The design further includes: the internal dimensions of the sealing ring are consistent with the external dimensions of the top of the mold body, and the upper mold cover is configured to lift via a piston rod and a hydraulic cylinder.

[0022] By adopting the above technical solution, the external oil pump equipment starts the hydraulic cylinder, causing hydraulic oil to be injected into the hydraulic cylinder to push the piston rod to work. During the extension and retraction of the piston rod, the upper mold cover is pushed to move up and down repeatedly, thereby performing mold closing and mold opening operations.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Please see Figures 1 to 3 A mold assembly for injection molding parts includes a base 1, a support frame 2 is mounted on one end of the top of the base 1, a hydraulic cylinder 3 is mounted on one end of the top of the support frame 2, and a piston rod 4 is inserted into the inside of the hydraulic cylinder 3.

[0030] The bottom of the piston rod 4 is fitted with an upper mold cover 5, and one end of the top of the upper mold cover 5 is provided with an injection port 6.

[0031] The bottom of the upper mold cover 5 has a groove 7, and a sealing ring 8 is fitted inside the groove 7.

[0032] Support plates 9 are installed at both ends of the top of the base 1 by screws. Support covers 10 are installed at both ends of one side of the support plates 9 by screws. A handle 11 is provided on one side of the support cover 10. A screw rod 12 is installed on one side of the handle 11. A retaining frame 13 is threadedly connected to the surface of the screw rod 12.

[0033] The upper surface of the base 1 has two sliding grooves 14 at the middle of the upper surface. The mold body 15 is slidably connected inside the sliding grooves 14. Several slots 16 are provided at the bottom of both sides of the mold body 15.

[0034] In this embodiment, as Figure 3 As shown, the support plate 9 has several through slots 17 at both ends, and the internal dimensions of the through slots 17 and the card slots 16 are consistent with the external dimensions of the card frame 13.

[0035] In this embodiment, as Figure 3 As shown, a rotating groove 18 is provided in the middle of one end of the support plate 9 near the through groove 17. One end of the screw 12 is rotatably installed inside the rotating groove 18, and the other end of the screw 12 is rotatably installed on one side of the inner wall of the support cover 10. The clamp frame 13 forms a transmission structure with the screw 12 and the handle 11.

[0036] In this embodiment, as Figure 2 As shown, a handle is installed on one side of the mold body 15, and the mold body 15 forms a pull-out structure with the slide groove 14 through the handle.

[0037] In this embodiment, as Figure 2 As shown, the internal dimensions of the sealing ring 8 are consistent with the external dimensions of the top of the mold body 15, and the upper mold cover 5 forms a lifting structure with the piston rod 4 and the hydraulic cylinder 3.

[0038] The working process of this mold assembly for injection molding parts is as follows:

[0039] First, the operator inserts the bottom end of the mold body 15 into the opening of the slide groove 14. Then, the operator pushes the handle, causing the bottom end of the mold body 15 to slide into the slide groove 14 until the mold body 15 can no longer be pushed. At this point, the slots 16 on both sides of the bottom of the mold body 15 will align with the positions of the pre-set retaining frames 13, eliminating the need for complex screw hole alignment and adjustment. Next, the operator rotates the handle 11 one by one, causing the screw 12 to rotate. At this point, the surface of the retaining frame 13 is restricted by the through groove 17 and will not rotate along the screw 12. Then, using the thread transmission force, the retaining frame 13 is moved along the surface of the screw 12 until one end gradually passes through the through groove 17 and is embedded in the inner cavity of the retaining groove 16, thus engaging with the retaining groove 16 and fixing the mold. The main body 15 is locked to prevent the need for strenuous operation of rotating bolts or screws. Then, an external oil pump can be connected to start the hydraulic cylinder 3 (model: HSG63), which injects hydraulic oil into the hydraulic cylinder 3 to drive the piston rod 4. During the extension and retraction of the piston rod 4, the upper mold cover 5 is pushed up and down repeatedly to perform mold closing and demolding operations. Finally, the raw material can be injected into the mold body 15 through the injection port 6 for injection molding. After the operation is completed, the mold can be demolded. When it is necessary to replace or disassemble the mold body 15 for cleaning, the same operation method can be used: reverse the handle 11 to release the locking of the mold body 15, and pull the handle to remove the used mold body 15.
