Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an injection molding machine with a rapid injection mechanism. Background Technology

[0002] Injection molding machines are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. The injection system consists of a plasticizing device and a power transmission device.

[0003] The authorized patent application with application number 202420469010.9 includes an injection molding machine body. A hydraulic cylinder is installed on one side inside the injection molding machine body. The output end of the hydraulic cylinder is fixedly connected to a first mold. A second mold is fixedly installed on the other side inside the injection molding machine body. A cooling cover is installed on the outside of the second mold. A material storage tank is provided on one side of the injection molding machine body. A discharge pipe is fixedly connected to the bottom of the material storage tank. An injection pipe is provided below the material storage tank. A fixing plate is installed on one side of the injection pipe.

[0004] The problem with the aforementioned comparative document is that it lacks a quantitative addition function, which makes it easy for the molten plastic in the storage tank to exceed the limit. After injection molding is completed, when the stirring motor and heating tube on the storage tank stop working, the excess molten plastic will gradually cool and solidify in the storage tank. This not only wastes the molten plastic but also affects the internal structure of the storage tank, making it difficult to continue normal use. Therefore, an injection molding machine with a rapid injection mechanism is proposed. Utility Model Content

[0038] Compared with the prior art, the beneficial effects of this utility model are:

[0039] 1. When using this utility model, the molten plastic needs to be injected into the storage tank first. Then, the hydraulic cylinder is activated to push the first mold and the second mold to the left to merge. The coolant in the cooling box can quickly cool down the molten plastic between the first mold and the second mold, thereby improving the molding plastic of the molten plastic in the first mold and the second mold.

[0040] 2. In use, the sealing plate is opened, and the molten plastic enters the storage tank through the feed port. During the injection molding process, the first motor can be started, which drives the stirring shaft to rotate. The stirring rod and heating tube on the stirring shaft can heat and stir the molten plastic. The side scraper can scrape the molten plastic off the inner wall of the storage tank. The molten plastic enters the injection tube from the discharge pipe and the feed pipe. The second motor on the injection tube can drive the spiral shaft to rotate and feed the material. The spiral shaft can push the molten plastic evenly into the connecting pipe. The molten plastic then enters the mold cavity of the second mold through the injection port. This structure realizes the function of facilitating uniform feeding.

[0041] 3. In use, this invention first sets a preset value for the controller based on the amount of molten plastic required for injection molding. The storage tank, by its own weight, applies pressure to the pressure sensor via the detection block and fixed side plate. The pressure sensor transmits the collected pressure information to the controller, which converts this pressure information into data. When this data equals the preset value, it indicates that the amount of molten plastic in the storage tank has reached the required amount for injection molding. At this point, the controller sends a command to the alarm, which alerts the operator to stop adding more molten plastic to the storage tank. This design enables the quantitative addition of molten plastic. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0053] like Figure 1-2 As shown, this utility model embodiment provides an injection molding machine with a fast injection mechanism, including a feeding assembly 2, which is installed on the left end of the injection assembly 1;

[0054] The injection molding assembly 1 includes horizontal guide rods 105, a left mounting block 108, a hydraulic cylinder 101, a first mold 109, and a second mold 106. The horizontal guide rods 105 are all arranged horizontally, and there are four horizontal guide rods 105. The four horizontal guide rods 105 are fixedly installed in a rectangular array on the left end of the right mounting block 102. The left mounting block 108 is fixedly installed on the left end of the four horizontal guide rods 105. The hydraulic cylinder 101 is fixedly installed at the middle position of the left end of the right mounting block 102. The first mold 109 is fixedly installed at the left output end of the hydraulic cylinder 101. The second mold 106 is fixedly installed on the right end of the left mounting block 108. The second mold 106 is located directly to the left of the first mold 109, and an injection port is provided on the left end of the second mold 106.

[0055] In this embodiment, the injection molding assembly 1 also includes guide side blocks 103. There are two guide side blocks 103. The two guide side blocks 103 are symmetrically fixedly installed at the upper and lower ends of the first mold 109. Guide ear plates 104 are fixedly installed at the front and rear ends of the two guide side blocks 103. The four guide ear plates 104 are slidably connected to the four horizontal guide rods 105 in the horizontal direction.

[0056] The injection molding assembly 1 also includes a cooling box 107, which is fitted onto the outside of the second mold 106 and contains coolant.

[0057] When using this invention, the molten plastic needs to be injected into the storage tank 205 first. Then, the hydraulic cylinder 101 is activated to push the first mold 109 and the second mold 106 to the left to merge. The coolant in the cooling box 107 can quickly cool down the molten plastic between the first mold 109 and the second mold 106, thereby improving the molding plastic of the molten plastic in the first mold 109 and the second mold 106.

[0058] When the first mold 109 moves horizontally, the horizontal guide rod 105 can guide the guide ear horizontally, thereby improving the stability of the first mold 109 drive.

[0059] like Figure 2-3 As shown, the feeding assembly 2 also includes an upper mounting frame 201, a mounting groove, a pressure sensor 213, a storage tank 205, a controller 211, and an alarm 212. The lower end of the right end of the upper mounting frame 201 is fixedly connected to the upper end of the left mounting block 108 via two first support rods. Two second support rods are symmetrically fixedly installed on the lower end of the left end of the upper mounting frame 201. The mounting groove is opened at the lower end of the upper mounting frame 201. The pressure sensor 213 is fixedly installed at the top of the inside of the mounting groove. A detection block 202 is fixedly installed at the lower end of the sensing end of the pressure sensor 213. The lower end of the detection block 202 slides through the lower end of the upper mounting frame 201 and extends to the bottom of the upper mounting frame 201. The upper end of the storage tank 205 has a feeding port, and a sealing plate is installed at the feeding port. Two fixed side plates 203 are symmetrically fixedly installed at the upper end of the storage tank 205. The two fixed side plates 203 are symmetrically fixedly installed at the lower end of the detection block 202. The controller 211 and the alarm 212 are both fixedly installed inside the mounting groove.

[0060] The feeding assembly 2 also includes a first motor 204, a stirring rod 216, and a side scraper 215. The first motor 204 is fixedly installed on the upper end of the storage tank 205. The lower end of the output shaft of the first motor 204 passes through the upper end of the storage tank 205 and extends into the interior of the storage tank 205. It is fixedly connected to a vertically arranged stirring shaft 214. There are multiple stirring rods 216, which are symmetrically fixedly installed on the left and right ends of the stirring shaft 214. A heating tube is installed inside the stirring rod 216. There are two side scrapers 215. The two side scrapers 215 are fixedly connected to the other end of the multiple stirring rods 216 located on the same side of the stirring shaft 214. The other end of the side scraper 215 is in contact with the inner wall of the storage tank 205.

[0061] The feeding assembly 2 also includes a discharge pipe 206, an injection pipe 208, and a connecting pipe 207. The discharge pipe 206 is fixedly connected to the lower end of the storage tank 205. A switch valve is installed on the discharge pipe 206 to control the opening and closing of the discharge pipe 206. The bottom of the discharge pipe 206 is movably inserted into the feeding pipe 209, that is, the feeding pipe 209 does not apply force to the discharge pipe 206, so that the pressure sensor 213 can collect the pressure information given by the storage tank 205. The injection pipe 208 is set horizontally. The feeding pipe 209 is fixedly connected to the upper end of the left end of the injection pipe 208. The connecting pipe 207 is fixedly connected to the right end of the injection pipe 208. The right end of the connecting pipe 207 passes through the left mounting block 108 and is connected to the injection port at the left end of the second mold 106.

[0062] The feeding assembly 2 also includes a second motor 210, which is fixedly installed on the left end of the injection tube 208. The right end of the output shaft of the second motor 210 passes through the left end of the injection tube 208 and extends into the inside of the injection tube 208, and is fixedly connected to a horizontally arranged spiral shaft 217.

[0063] Pressure sensor 213 is electrically connected to controller 211, and controller 211 is electrically connected to alarm 212.

[0064] Opening the sealing plate allows molten plastic to enter the storage tank 205 through the inlet. During injection molding, the first motor 204 can be started, driving the stirring shaft 214 to rotate. The stirring rod 216 and heating tube on the stirring shaft 214 can heat and stir the molten plastic. The side scraper 215 can scrape the molten plastic off the inner wall of the storage tank 205. The molten plastic enters the injection tube 208 through the outlet pipe 206 and the inlet pipe 209. The second motor 210 on the injection tube 208 can drive the spiral shaft 217 to rotate and feed the material. The spiral shaft 217 can push the molten plastic evenly into the connecting pipe 207. The molten plastic then enters the cavity of the second mold 106 through the injection port. This structure facilitates uniform feeding.

[0065] The controller 211 is a general-purpose SC200 controller. First, a preset value is set for the controller 211 according to the amount of molten plastic required for injection molding. The storage tank 205, by its own weight, can apply pressure to the pressure sensor 213 through the detection block 202 and the fixed side plate 203. The pressure sensor 213 transmits the collected pressure information to the controller 211. The controller 211 converts the pressure information into data. When the data is equal to the preset value, it means that the amount of molten plastic in the storage tank 205 has reached the amount required for injection molding. At this time, the controller 211 can send a command to the alarm 212. The alarm 212 will sound an alarm to remind the staff to stop pouring molten plastic into the storage tank 205.
