Description

Technical Field

[0001] This utility model relates to the technical field of pre-plastic seat production molding device, and in particular to a molding device for producing a single-cylinder hydraulic pre-plastic seat. Background Technology

[0002] The pre-plasticizing seat is a key component in an injection molding machine, mainly used to control the pre-plasticizing process. The pre-plasticizing seat usually includes a hollow shell with an oil seal cover at the front opening. Inside, there are components such as a top shaft and top shaft gear. The molding device for producing a single-cylinder hydraulic pre-plasticizing seat injects molten raw material into the mold after melting the raw material, and then the molten raw material is formed in the mold, thus producing the single-cylinder hydraulic pre-plasticizing seat.

[0003] Existing molding devices for producing single-cylinder hydraulic pre-plasticizing seats typically use screw feeding. In the initial stage of screw feeding, the raw material at the screw end is insufficient, failing to meet the injection conditions and resulting in material waste in the early stages. This has certain adverse effects on the user experience. To address the shortcomings of existing technologies, we propose a molding device for producing single-cylinder hydraulic pre-plasticizing seats. Utility Model Content

[0004] The main objective of this invention is to provide a molding device for producing single-cylinder hydraulic pre-plastic seats, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A molding device for producing a single-cylinder hydraulic pre-plasticized seat includes a molding device body. A base is detachably installed at the bottom of the molding device body, and a hopper is detachably installed at the top of the molding device body. A drive motor is detachably installed at one end of the molding device body, and a feeding screw is detachably installed at one output end of the drive motor. A partition is detachably installed on one side of the inner wall of the molding device body, and a first heating tube is detachably installed on one side of the inner wall of the molding device body. A second heating tube is detachably installed on one side of the inner wall of the first heating tube. A conical sleeve is movably sleeved on the outer side of one end of the second heating tube. Metal springs are symmetrically and detachably installed on the inner wall of the conical sleeve, and one side of the metal springs abuts against the outer side of one end of the second heating tube.

[0007] Preferably, the top of the molding device body has a discharge hole, and a movable plate is rotatably connected to one side of the inner wall of the discharge hole of the molding device body. The discharge hole of the molding device body is connected to the inside of the discharge hopper.

[0008] Preferably, the outer side of the feeding screw abuts against the inner wall of the forming device body, and a protrusion is detachably installed on the outer side of one end of the feeding screw.

[0009] Preferably, a fixed mold is detachably installed on one side of the top of the base, and one side of the fixed mold is detachably installed to one end of the main body of the molding device.

[0010] Preferably, a hydraulic push rod is detachably installed on one side of the top of the base, and a moving mold is detachably installed on one end of the hydraulic push rod.

[0011] Preferably, a through hole is provided on one side of the partition, and the interior of the through hole in the partition is movably connected to one end of the conical sleeve.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the raw material is conveyed by the feeding screw and piled up in front of the conical sleeve and the partition. After the raw material is piled up, the conical sleeve is pushed open and enters the space between the first heating tube and the second heating tube through the partition for melting. This reduces the waste of raw material in the front section. The partition also improves the sealing between the first heating tube and the second heating tube, improves the heat preservation effect, and makes the melting effect better.

[0014] 2. In this utility model, when the feeding screw rotates, it drives the protrusion to move the movable plate to clear the raw material at the bottom of the hopper, making the hopper discharge more smoothly and less prone to blockage, improving the discharge efficiency, and making the device more convenient to use.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4As shown, a molding device for producing a single-cylinder hydraulic pre-plastic seat involves feeding raw materials into a hopper 3. The raw materials in the hopper 3 fall into the molding device body 1 through a feeding hole. The drive motor 4 is started, and its output drives the feeding screw 5 to rotate. The rotation of the feeding screw 5 causes the raw materials fed into the molding device body 1 by the hopper 3 to reach the end of the partition 6. At this point, the raw materials at the end of the partition 6 accumulate on one side of the partition 6 due to the blockage caused by the partition 6 and the conical sleeve 9, until the feeding screw 5 continuously supplies raw materials, thus reducing the accumulation of raw materials. After the material is piled up on one side of the partition 6, the conical sleeve 9 is pushed by the subsequent raw material to push the metal spring 10 on one end of the second heating tube 8. The metal spring 10 is tightly attached to the inner wall of the conical sleeve 9. The metal spring 10 no longer supports the conical sleeve 9 based on the second heating tube 8. After losing the support of the metal spring 10, the conical sleeve 9 is pushed by the raw material to fit onto the second heating tube 8. At this time, one end of the conical sleeve 9 is separated from the through hole opened in the partition 6. The piled raw material is fully fed into the outside of the conical sleeve 9 fitted with the second heating tube 8 through the through hole opened in the partition 6, completing the process of the raw material being fully fed into the space between the first heating tube 7 and the second heating tube 8 from one end of the feeding screw 5 for melting.

[0022] After the first heating tube 7 and the second heating tube 8 melt the fed raw material, the molten raw material is injected through one end of the molding device body 1 into the mold formed by the moving mold 15 and the fixed mold 13 pushed by one end of the hydraulic push rod 14, thereby completing the production molding of the single-cylinder hydraulic pre-plastic seat.

[0023] Example 2, as Figure 2 and Figure 4 As shown, a molding device for producing a single-cylinder hydraulic pre-plastic seat, when conveying raw materials into the molding device body 1 via a feeding screw 5 to a hopper 3, the feeding screw 5 rotates, causing a protrusion 12 to rotate around the feeding screw 5 as an axis. When the feeding screw 5 rotates, it causes the protrusion 12 to push one end of a movable plate 11 that extends into the molding device body 1. The protrusion 12 pushes the movable plate 11 to shake against the inner wall of the discharge hole opened in the molding device body 1, so that the other end of the movable plate 11 extending into the bottom of the hopper 3 shakes inside the hopper 3. The shaking movable plate 11 clears the raw materials at the bottom of the hopper 3, making it less likely for the raw materials in the hopper 3 to become blocked when entering the discharge hole opened in the molding device body 1, thus achieving the purpose of clearing the discharge.

[0024] It should be noted that this utility model is a molding device for producing a single-cylinder hydraulic pre-plastic seat. In use, the drive motor 4 drives the feeding screw 5 to drive the protrusion 12. The protrusion 12 drives the movable plate 11 to clear the raw material at the bottom of the feeding hopper 3. After the raw material in the feeding hopper 3 enters the main body 1 of the molding device, it is transported and piled up in front of the conical sleeve 9 and the partition 6 by the rotating feeding screw 5. Under the push of the piled raw material, the conical sleeve 9 is pushed open and the metal spring 10 is put on one end of the second heating tube 8. The piled raw material enters the space between the first heating tube 7 and the second heating tube 8 through the through hole opened in the partition 6 to melt, reducing the waste of raw material in the front section.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
