Description

Technical Field

[0001] This utility model relates to the technical field of hollow blow molding equipment, specifically a hollow blow molding machine with an extrusion protection structure. Background Technology

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. A tubular plastic preform, obtained by extrusion or injection molding of thermoplastic resin, is placed in a split mold while hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the preform, causing it to inflate and adhere tightly to the inner wall of the mold. After cooling and demolding, various hollow products are obtained. However, existing blow molding machines lack a protective structure on the outer side of the extrusion die, making it easy for dust and other foreign objects to adhere to the material during die feeding, thus affecting the quality of the products produced by the blow molding machine.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Please see Figure 1-5In this embodiment of the utility model, a hollow blow molding machine with an extrusion protection structure includes: a hollow blow molding machine body 100, a protective mechanism 200, and a cutting mechanism 300. The protective mechanism 200 is disposed on the outside of the extrusion die of the hollow blow molding machine body 100. The protective mechanism 200 includes a fixing plate 210. A protective shell 220 is disposed at the bottom of the fixing plate 210. The protective shell 220 is provided with a placement groove 221 and a sliding through hole 222. A protective shell 230 is slidably connected inside the placement groove 221. The protective shell 230 is provided with a sliding through hole 231. The tops of the protective shell 220 and the protective shell 230 are in contact with the fixing plate 210. The protective shell 220 and the protective shell 230 are respectively disposed on the outside of two molds. The cutting mechanism 300 is disposed on the outside of the protective mechanism 200.

[0033] Specifically, the fixed plate 210, protective shell 1 220, protective shell 230 and cutting mechanism 300 are used together to shield and protect the material extruded from the extrusion die head, preventing the material from sticking to dust and other foreign objects before it falls between the two molds, thereby improving the quality of the products produced by the blow molding machine body 100. In addition, protective shell 1 220 and protective shell 230 can move simultaneously with the two molds, making it more convenient to use.

[0034] like Figure 3-5 As shown, in this embodiment, the cutting mechanism 300 includes: a fixed shell 310 and a hot cutting blade 340. The fixed shell 310 is fixedly connected to the hollow blow molding machine body 100. A sliding through hole 311 is provided on the fixed shell 310, and a pushing assembly is provided inside the fixed shell 310. The hot cutting blade 340 is disposed on one side of the fixed shell 310, and a shielding assembly is provided on the outer side of the hot cutting blade 340. A guide assembly is provided on the shielding assembly. The pushing assembly includes: a cylinder 320 and a moving plate 330. The cylinder 320 is fixedly connected to the inner wall of the fixed shell 310, and the moving plate 330 is fixedly connected to the output end of the cylinder 320. The moving plate 330 is slidably connected to the interior of the fixed shell 310. A moving block 331 is fixedly connected to the moving plate 330, and the moving block 331 is slidably connected to the sliding through hole 311. The three holes 311 are slidably connected, and one end of the moving block 331 is fixedly connected to the hot cutting blade 340. The shielding assembly includes: a connecting rod 350, a shielding rod 370 and a shielding rod 380. The connecting rod 350 is located on the outside of the fixed shell 310. A sliding groove 351 is provided on the connecting rod 350, and two sliders 353 are slidably connected inside the sliding groove 351. The shielding rod 370 and the shielding rod 380 are respectively located on the outside of the two sliders 353. A rectangular hole 371 is provided on the shielding rod 370, and the rectangular hole 371 is sleeved and fixed to the outside of the hot cutting blade 340. A rectangular hole 381 is provided on the shielding rod 380. The shielding rod 370 is slidably connected to the sliding through hole 222, and the shielding rod 380 is slidably connected to the sliding through hole 231.

[0035] In this embodiment, by activating the cylinder 320, the moving plate 330, the moving block 331, and the hot cutting blade 340 are moved. The moving hot cutting blade 340 facilitates the cutting of the extruded material. The movement of the hot cutting blade 340 also causes the first shielding rod 370, the connecting rod 350, and the second shielding rod 380 to move synchronously. The first shielding rod 370 and the second shielding rod 380 then block the first sliding through hole 222 and the second sliding through hole 231, thereby preventing dust and other foreign objects from passing through the first sliding through hole 222 and the second sliding through hole 231 and entering the interior of the first protective shell 220 and the second protective shell 230 when cutting the material. This improves the practicality of the hollow blow molding machine with extrusion protection structure.

[0036] like Figure 3 As shown, in this embodiment, the guide assembly includes an L-shaped plate 360, which is fixedly connected to the fixed shell 310. A rectangular plate 361 is fixedly connected to the L-shaped plate 360, and a second sliding groove 362 is provided on the rectangular plate 361. A guide rod 363 is provided at one end of the L-shaped plate 360. The top of the guide rod 363 is slidably connected to the second sliding groove 362, and the bottom of the guide rod 363 is fixedly connected to the connecting rod 350.

[0037] In practice, the rectangular plate 361, the second slide groove 362, and the guide rod 363 are used together to facilitate the support, limiting, and guiding of the connecting rod 350, thereby ensuring the stability of the connecting rod 350, the first blocking rod 370, and the second blocking rod 380 when they move.

[0038] Example 2

[0039] Based on Embodiment 1, in order to facilitate the disassembly and cleaning of Protective Shell 1 220, Protective Shell 2 230, Barrier Rod 1 370 and Barrier Rod 2 380.

[0040] like Figure 2-5 As shown, in this embodiment, the width of the fixing plate 210 is the same as the width of the protective shell 220. Both the protective shell 220 and the protective shell 230 are screwed together with multiple connecting bolts 240, and the multiple connecting bolts 240 are screwed together with the two molds respectively. The inner side wall of the sliding groove 351 is provided with a sliding through hole 352. Both ends of the connecting rod 350 are provided with fixing bolts 390, and the two fixing bolts 390 are screwed together with the two sliders 353 respectively. One end of the shielding rod 370 and the shielding rod 380 are screwed together with one end of the two fixing bolts 390 respectively.

[0041] In practice, by unscrewing two fixing bolts 390, it is easy to separate the first shielding rod 370 and the second shielding rod 380 from the two sliders 353, thereby facilitating the disassembly and cleaning of the first shielding rod 370 and the second shielding rod 380. By unscrewing multiple connecting bolts 240, it is easy to disassemble and clean the first protective shell 220 and the second protective shell 230, making it more convenient to use.
