Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an injection mold that facilitates control of material flow speed. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects, and injection molds are one of many types of molds.

[0003] Utility model patent CN210758943U discloses an injection mold with easy heat dissipation, including a top plate, a bottom plate, a lower mold, and an upper mold, as well as a base. Two oppositely distributed side plates are installed on the top surface of the base. The injection mold is mounted on the top surface of the base via the bottom plate and is located inside the two side plates. Cooling fans are installed on the opposite sides of the two side plates. Inlet pipes and outlet pipes are installed on the two sides of the upper mold, and cooling channels communicating with both the inlet and outlet pipes are formed inside the upper mold. The injection mold can cool down the mold from both the outside and the inside through the cooling fans and cooling channels, resulting in high cooling efficiency and high molding efficiency of the plastic parts. After the upper and lower molds are closed, a manual auxiliary stabilizing component is used for further stabilization to prevent the mold from shaking during injection, thereby improving stability and the quality of the plastic parts.

[0004] However, existing injection molds still have some shortcomings: First, most existing injection molds use a single-structure injection port to inject the injection liquid. Due to factors such as the uncontrollable flow rate of the injection liquid, it is easy to cause waste of the injection liquid. Utility Model Content

[0026] The present invention will now be described in further detail in conjunction with the full text.

[0027] Combined with appendix Figures 1-4 An injection mold for easy control of material flow rate includes an upper mold 1 and a lower mold 2. A limiting block 3 is installed on the lower mold 2. A mold cavity 4 is opened between the upper mold 1 and the lower mold 2. A material conveying pipe 5 is installed on the limiting block 3 and the material conveying pipe 5 communicates with the mold cavity 4. A guide hole 6 is opened on the upper mold 1 to cooperate with the material conveying pipe 5. A conveying housing 7 communicating with the guide hole 6 is installed on the upper mold 1. An adjusting device 8 for controlling the material flow rate is installed inside the conveying housing 7.

[0028] In specific implementation of this utility model, such as Figure 2 As shown. The material conveying pipe 5 includes a guide pipe 501 and a diversion pipe 502 that connects to the guide pipe 501. The guide pipe 501 can be inserted into the through hole 6. The other end of the diversion pipe 502 connects to the mold cavity 4. Specifically, the guide pipe 501 has a structure that is smaller at the top and larger at the bottom, and the through hole 6 is used in conjunction with the guide pipe 501. This structure can effectively allow the material flow to enter the guide pipe 501 and then be diverted from the guide pipe 501 into the diversion pipe 502.

[0029] In specific implementation of this utility model, such as Figure 1 and Figure 3 As shown, the adjusting device 8 includes a limiting shell 801 connected to one side of the conveying shell 7. A stop block 802, which can adjust and block the conveying shell 7, is installed inside the limiting shell 801. An adjusting spring 803 is installed on one side of the stop block 802. A stepping device 9, which pushes the adjusting spring 803, is installed on one side of the limiting shell 801. A feed hole 10 is provided on the stop block 802. The stepping device 9 includes a stepping bolt 901 threadedly connected to the limiting shell 801. A push plate 902 is installed on one side of the stepping bolt 901 and inside the limiting shell 801. Specifically, the stepping bolt 901 can rotate and move along the thread on the limiting shell 801, causing the push plate 902 to move closer to the adjusting spring 803. Adjusting the distance between the adjusting spring 803 and the push plate 902 adjusts the force distance on the stop block 802, thereby changing the retraction distance of the stop block 802 under the influence of the adjusting spring 803.

[0030] One end of the adjusting spring 803 is located on one side of the push plate 902. When the adjusting spring 803 is close to the push plate 902, it is in contact. When the adjusting spring 803 is away from the push plate 902, it is not in contact.

[0031] like Figure 3 As shown, an adjustable baffle 11 is installed inside the limiting shell 801 and above the stop block 802. The lower end of the conveying shell 7 is an hourglass structure, and the upper end of the conveying shell 7 is connected to the external feed pipe. The baffle 11 is mirror-image set and has a through hole. A fixed shaft is installed inside the conveying shell 7. The baffle 11 is sleeved on the outside of the fixed shaft through the through hole. A torsion spring is installed inside the through hole, and one end of the torsion spring is connected to the inner wall of the through hole, while the other end is fixedly connected to the fixed shaft. When the material enters the conveying shell 7 from the feed pipe and touches the baffle 11, it will rotate downward due to gravity and pressure. The torsion spring will then work to complete the feeding.

[0032] The lower end of the upper mold 1 is fitted with a positioning angle 12, and the lower mold 2 has a positioning groove 13 that is fitted with the positioning angle 12.

[0033] The working principle of this utility model:

[0034] First, the stepping bolt 901 rotates and moves on the upper thread of the limiting shell 801, which can drive the push plate 902 to approach the adjusting spring 803. Adjusting the distance between the adjusting spring 803 and the push plate 902 adjusts the force distance of the stop block 802, thereby changing the contraction distance of the stop block 802 under the adjustment spring 803. When the upper mold 1 approaches the lower mold 2, the guide tube 501 is inserted into the through hole 6 to connect the conveying shell 7. The material enters the conveying shell 7 from the feed pipe and touches the baffle 11. Due to gravity and pressure, the baffle 11 will rotate downward, the torsion spring will work, and the material will continue to move downward, pushing the stop block 802 to move. The adjusting spring 803 will move and when it touches the push plate 902, it will be compressed and the material will enter the guide tube 501 downward. Then, it will enter the diversion tube 502 through the guide tube 501 and enter the mold cavity 4 formed between the upper mold 1 and the lower mold 2 for strip forming.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
