Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of feeding, and in particular to a feeding structure of an injection molding machine with a drying function. Background Art
[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding machines are divided into vertical, horizontal and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics to make them ejected and fill the mold cavity.
[0003] Existing injection molding machines usually have a funnel-type feed hopper directly on the top of the machine body. When working, granular plastic is directly poured into the funnel-type feed hopper and directly discharged for heating and melting. However, since the plastic particles purchased on the market generally contain some moisture on the surface after being placed for a long time, it is easy to cause bubbles and cavities in the molten plastic raw materials if they are directly poured into the funnel-type feed hopper for discharge, thereby destroying the structure of the manufactured plastic product, and in severe cases affecting the quality of the injection molded plastic product. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.
[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0026] Refer to the attached Figure 1-3 In this embodiment, a feeding structure of an injection molding machine with a drying function includes a feeding silo 1 with two ends passing through, the feeding silo 1 includes an inclined section 101 and a vertical feeding section 102 integrally formed at the top of the inclined section 101, and the bottom end of the inclined section 101 is correspondingly installed on the body of the injection molding machine. A vertically adjustable baffle 4 is correspondingly installed on the inner wall of the vertical feeding section 102 close to the inclined section 101. A first air cavity 103 is correspondingly provided inside the bottom wall of the inclined section 101 on the feeding silo 1, and a plurality of first air holes 104 are evenly opened on the inner wall of the first air cavity 103. The aperture of the first air hole 104 is smaller than the size of the plastic particles, and the first air cavity 103 can be correspondingly connected to the air outlet of the hot air blower 3. A second air cavity 105 is correspondingly provided inside the top wall of the inclined section 101 of the feed silo pipe 1, and a plurality of second air holes 106 are evenly opened on the inner wall of the second air cavity 105. The top of the second air cavity 105 close to the vertical feed section 102 can be connected to the outside air.
[0027] Specifically, the second air cavity 105 can be extended upwardly to form a vertical third air cavity near the vertical feeding section 102, and the third air cavity is correspondingly located inside the side wall of one side of the vertical feeding section 102, and the top of the third air cavity is correspondingly provided with a strip air outlet 107. The hot air blower 3 can be correspondingly installed on the outer bottom wall of the inclined section 101 of the feeding silo 1, or directly installed on the injection molding machine body or elsewhere. During operation, the hot air blower 3 can be used to blow hot air into the first air chamber 103, and the hot air will be blown upward through the first air hole 104 to heat and dry the plastic particles passing through the inclined section 101 of the feed bin pipe 1, while the hot air blown upward will pass through the second air hole 106 into the second air chamber 105, and finally blown out to the outside from the strip air outlet 107 at the top of the second air chamber 105. The overall design is ingenious. The strip air outlet 107 is arranged on one side of the vertical feed section, which can also better prevent dust from falling in the second air chamber 105.
[0028] A vertical clip strip 7 is provided on the front and rear inner walls of the vertical feed section 102 on the side close to the inclined section 101, and a vertical through-clip slot is provided on the front and rear ends of the baffle 4, and the two ends of the baffle 4 are slidably mounted on the clip strip 7. A first magnetic plate 5 is embedded in the side of the baffle 4 that fits the inner wall of the vertical feed section 102, and a second magnetic plate 6 is embedded in the side of the inner wall of the vertical feed section 102 that fits the baffle 4. The first magnetic plate 5 can be magnetically fixed to the second magnetic plate 6. When operating, the baffle 4 is directly pushed to any height and then stopped, and the baffle 4 will be fixed under magnetic adsorption. This embodiment can effectively control the flow density of plastic particles flowing through the inclined section 101 by controlling the distance between the baffle 4 and the bottom wall of the inclined section 101 below it, so as to further improve the drying effect. It is worth noting that there are many ways to control the lifting of the baffle 4, such as using an electric push rod to control the lifting of the baffle 4, etc., and no specific limitation is made here.
[0029] A feed hopper 2 may be correspondingly provided at the top of the vertical feed section 102 on the feed silo pipe 1, and the top diameter of the feed hopper 2 is larger than the diameter of the vertical feed section 102, so as to better pour in the plastic particles.
