[0002] Injection molding is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product dimensions. The product is easy to update and can be made into parts with complex shapes. The raw materials for injection molding need to be mixed.

[0003] The patent specification with application number CN201921552641.2 discloses a production and processing device for injection molding particles for rubber shoes, including a mixing box, a first lifting cylinder and a second lifting cylinder, wherein the first lifting cylinder is installed inside the mixing box, and the first lifting cylinder is connected to the second lifting cylinder through a first branch pipe, a second branch pipe, a third branch pipe and a fourth branch pipe. The first lifting cylinder is provided with a first lifting rod and a first spiral leaf, and the second lifting cylinder is provided with a second lifting rod and a second spiral leaf.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned injection molding particle production and processing device has the following problems: a lifting cylinder structure is set inside the mixing box to reduce the friction of the material, however, the stirring structure is relatively fixed and cannot be adjusted up and down. In order to ensure normal stirring, the stirring rod is generally set at the center of the stirring cylinder for continuous stirring. Therefore, the material at the bottom and top is basically not stirred, which seriously affects the stirring progress and effect of the injection molding process. For this reason, we propose a material mixing device for injection molding. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 to Figure 4 As shown, this embodiment proposes a material mixing device for injection molding, including a base 1, a servo motor 2 5 is fixedly arranged at the top center position of the base 1, a stirring shaft 6 is fixedly arranged at the end of the main shaft of the servo motor 2 5, and an adjustable material table 2 is passed through the end of the main shaft of the servo motor 2 5. The adjustable material table 2 serves as a sealing structure at the bottom of the mixing barrel 10, and is lifted and lowered in cooperation with the mixing barrel 10 to improve the sealing effect. The outer side of the adjustable material table 2 also includes a lifting component 3;

[0029] The lifting assembly 3 includes a positioning frame 31 as a lifting guide structure, and the positioning frame 31 is fixedly arranged with the adjustable material platform 2. A vertical shaft 32 runs through the interior of the positioning frame 31, and the vertical shaft 32 is fixedly arranged with the base 1. The adjustable material platform 2 can be positioned to the outside of the vertical shaft 32 through the outer positioning frame 31 to move up and down. A mixing barrel 10 is inserted into the top of the adjustable material platform 2, and a limiting ring 35 is fixedly arranged on the outside of the mixing barrel 10. The limiting ring 35 can limit the mixing barrel 10, keep the positioning, and control the synchronous lifting and lowering of the mixing barrel 10. A slip ring 36 is fixedly arranged on the outside of the limiting ring 35, and a threaded shaft 37 is spirally arranged inside the slip ring 36. A servo motor 38 is fixedly arranged at the bottom end of the threaded shaft 37, and the servo motor 38 is fixedly arranged with the base 1. The servo motor 38 drives the threaded shaft 37 to rotate, thereby controlling the lifting and lowering of the limiting ring 35.

[0030] In this embodiment, a spring 33 is sleeved on the outer side of the vertical axis 32 , and the bottom end of the spring 33 is pressed against the outer side of the base 1 . The spring 33 has a buffering effect and supports the adjustable material table 2 .

[0031] A support ring 34 is tightly disposed at the other end of the spring 33 , and the support ring 34 is tightly pressed against the bottom end surface of the positioning frame 31 . The spring 33 cooperates with the support ring 34 to improve the stability of supporting the positioning frame 31 .

[0032] There are four positioning frames 31 in total, and the positioning frames 31 are evenly distributed around the adjustable material table 2 . The four positioning frames 31 can maintain the guiding stability of the adjustable material table 2 .

[0033] A second vertical axis 310 is fixedly provided at one corner of the top of the base 1 , a guide frame 39 is slidably provided outside the second vertical axis 310 , and the guide frame 39 is fixed to the limiting ring 35 , and the second vertical axis 310 can further improve the stability of guiding the guide frame 39 .

[0034] The height of the second vertical axis 310 is the same as that of the first vertical axis 32. A round anti-drop block is provided at the top of the first vertical axis 32. The first vertical axis 32 is the same height as the second vertical axis 310, which can maintain the raised height of the positioning frame 31. The design of the round anti-drop block prevents the positioning frame 31 from falling off.

[0035] Example 2

[0036] like Figure 1 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a discharge pipe 4 is passed through the interior of the adjustable platform 2, and an inclined channel is provided inside the discharge pipe 4, so that the discharge pipe 4 can conveniently guide the mixed raw materials to be discharged.

[0037] In this embodiment, a triangular seat 7 is fixedly provided inside the top of the seasoning table 2, a sealing cover 8 is sleeved on the outer side of the triangular seat 7, and a bearing 9 is rotatably provided inside the triangular seat 7. The structural design of the bearing 9 can reduce the rotational friction of the main shaft and control the rotation of the stirring shaft 6 to be smoother.

[0038] Among them, servo motor 1 38 and servo motor 2 5 are prior art and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0039] Workflow and principle:

[0040] The staff adds the raw materials used for injection molding into the mixing barrel 10 through the material port at the top of the mixing barrel, connects to the external power supply, controls the servo motor 2 5 to work, drives the stirring shaft 6 at the end of the main shaft to start working, and the stirring shaft 6 rotates inside the mixing barrel 10 to quickly stir and mix the raw materials in the mixing barrel 10. During the stirring process, the servo motor 1 38 can be used to work, drive the threaded shaft 37 at the end of the main shaft to rotate, control the outer slip ring 36 to control the limit ring 35 to drive the mixing barrel 10 to rise and fall, and cooperate with the guide frame 39 on the outer side of the limit ring 35 to rise and fall on the vertical axis 1 32. As the mixing barrel 10 rises and falls, the internal stirring shaft 6 can quickly stir the raw materials at the bottom and top of the mixing barrel 10, thereby improving the mixing and stirring effect and progress of the mixed raw materials. At the same time, the guide frame 39 can move outside the vertical axis 2 310 to further improve the movement stability. The support ring 34 at the bottom of the positioning frame 31 cooperates with the spring 33 to perform efficient buffering to reduce the vibration of the mixing barrel 10.

[0041] The servo motor 2 5 passes through the triangular seat 7, the sealing cover 8 and the internal bearing 9 to reduce friction, rotate more stably, and accelerate the stirring effect of the raw materials inside the mixing barrel 10. After the stirring is completed, the material can be guided out from the inside of the discharge pipe 4.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
