DETAILED DESCRIPTION

[0033] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0034] Please refer to Figures 1 to 6 The utility model provides a portable injection molding tool, it includes: syringe 1, piston 2, heating mechanism 4 and vibration defoaming mechanism 5 for solving the problem that carrying multiple equipment and tool in prior art can cause the flexibility and mobility of manufacturing process to be limited.

[0035] Specifically, the piston 2 slides in the syringe 1, and a piston rod 3 is fixed to the top of the piston 2, the piston rod 3 is coaxially arranged with the piston 2 and extends out of the syringe 1; in order to facilitate the push-pull of the piston rod 3, a handle can be fixed to the upper end of the piston rod 3. By pushing and pulling the piston 2, the material in the syringe 1 can be injected into the mold.

[0036] The heating mechanism 4 is introduced as follows:

[0037] The heating mechanism 4 is arranged in the syringe 1 and can heat the raw material to melt it. Specifically, the piston 2 and the piston rod 3 are hollow, and the heating mechanism 4 can extend into the piston 2 and the piston rod 3, thereby uniformly heating the raw material in the syringe 1. The heating mechanism 4 includes a protective shell 401 fixed to the bottom of the syringe 1 and extending into the piston 2 and the piston rod 3, which protects the internal other structures and prevents the raw material from directly contacting the internal other structures. The protective shell 401 is fixed with a heating rod 402, and a sealing ring 403 tightly fitted with the protective shell 401 is fixed in the piston 2 to prevent the raw material in the syringe 1 from entering the piston 2 or the piston rod 3. When in use, the heating rod 402 works to heat the raw material in the syringe 1.

[0038] The vibration defoaming mechanism 5 is introduced as follows:

[0039] The vibration defoaming mechanism 5 is arranged in the syringe 1 and is used to eliminate the bubbles generated during heating, so that the quality of the soft bait is higher. Specifically, the vibration defoaming mechanism 5 includes a filler 501 fixed to the bottom of the syringe 1, and a vibration motor 502 is installed in the filler 501. When the vibration motor 502 works, the vibration force can be transmitted to the syringe 1 through the filler 501, thereby vibrating and defoaming the heated raw material in the syringe 1.

[0040] In the embodiment, the outer side of the needle cylinder 1 is provided with a heat insulation sleeve 6, which is convenient for the user to hold. The side of the heat insulation sleeve 6 is provided with at least one observation port 7, which is convenient for the user to observe the state of the raw material in the needle cylinder 1. The upper end of the heat insulation sleeve 6 is provided with a cover 8 for preventing the needle cylinder 1 from moving axially. After the cover 8 is opened, the needle cylinder 1 can be taken out, so that the needle cylinder 1 can be cleaned or repaired.

[0041] It is worth mentioning that the outer side of the heat insulation sleeve 6 is fixed with a control box 9. The control box 9 is provided with a controller. The heating mechanism 4 and the vibration defoaming mechanism 5 are connected with the controller through cables. In the embodiment, the heating rod 402 in the heating mechanism 4 and the vibration motor 502 in the vibration defoaming mechanism 5 are connected with the controller, so that the heating rod 402 and the vibration motor 502 can be controlled through the controller. In addition, the outer side of the control box 9 is provided with a power key 10, a temperature control knob 11, a display screen 12 and an indicator light 13. The power key 10, the temperature control knob 11, the display screen 12 and the indicator light 13 are connected with the controller through cables. In use, the power is connected, the device is started through the power key 10, and then the heating temperature is set through the temperature control knob 11 (the indicator light 13 is green, indicating that the heating is on, and the display screen 12 displays the heating temperature in real time). The heating rod 402 starts to heat.

[0042] After use, the raw material is easy to solidify on the inner wall of the needle cylinder 1. The traditional needle cylinder 1 is difficult to clean. In order to facilitate the cleaning of the needle cylinder 1, the following design is made:

[0043] The needle cylinder 1 comprises a lower cover 101, a first gasket 102, a transparent tube 103 and a second gasket 104, which are sequentially stacked in the heat insulation sleeve 6 from bottom to top. The lower cover 101 is fixed with an injection port 105 extending out of the heat insulation sleeve 6 and communicating with the transparent tube 103. The raw material melted in the transparent tube 103 is injected into the mold through the injection port 105. The first gasket 102 can seal the joint between the lower cover 101 and the transparent tube 103. The second gasket 104 can seal the joint between the upper end of the transparent tube 103 and the cover 8. The piston 2 slides in the transparent tube 103. The heating mechanism 4 and the vibration defoaming mechanism 5 are fixed to the inner top of the lower cover 101.

[0044] When the inside of the needle cylinder 1 needs to be cleaned, the piston rod 3 is first pulled out of the transparent tube 103. Then the cover 8 is unscrewed, so that the lower cover 101, the first gasket 102, the transparent tube 103 and the second gasket 104 can be poured out of the heat insulation sleeve 6, so that each part can be cleaned separately, which is convenient for repeated use.

[0045] It is necessary to supplement that the upper end of the cover 8 is hinged with an upper cover 14, and a buckle structure 15 is arranged between the upper cover 14 and the cover 8, so that the upper cover 14 and the cover 8 can be fixed through the buckle structure 15. The upper cover 14 cooperates with the cover 8 to form a containing groove 16 adapted to the piston 2, and a gap hole 17 for the piston rod 3 to pass through is arranged on the top of the upper cover 14. In use, the piston 2 is first pulled upward to be accommodated in the containing groove 16, as shown in Figure 5 Then the upper cover 14 is rotated to be opened, so that the raw material can be added into the syringe 1, as shown in Figure 6

[0046] In this embodiment, the inner diameter of the cover 8 is consistent with the inner diameter of the transparent tube 103, and the chamfer is 70 degrees, which is beneficial to the pushing of the piston 2. The depth of the containing groove 16 is slightly smaller than the thickness of the piston 2. When the piston 2 is pushed and pulled into the containing groove 16, and the rubber ring on the outer circle of the piston 2 is separated from the transparent tube 103, the rubber ring on the outer circle of the piston 2 contacts the upper cover 14 and the cover 8, so as to prevent the liquid from flowing out from the joint of the upper cover 14 and the cover 8.

[0047] In addition, the piston rod 3 is spirally installed with a locking ring 18 outside the upper cover 14, and the outer diameter of the locking ring 18 is greater than the diameter of the gap hole 17. The position of the locking ring 18 can be moved by rotation, so as to limit the pushing and pulling stroke of the piston 2, and further adjust the injection amount.

[0048] Work flow:

[0049] 1. Pull the piston 2 upward to the top of the containing groove 16, and then open the upper cover 14;

[0050] 2. Pour the raw material and auxiliary material into the syringe 1;

[0051] 3. Connect the power supply, start the tool, set the heating temperature through the temperature control knob 11, and the heating rod 402 starts heating;

[0052] 4. After heating, load the piston 2, push the piston 1, and inject the material into the mold.
