Description

Technical Field

[0001] This utility model relates to the field of blow molding mold technology, specifically to a mold gate scraper structure. Background Technology

[0002] In the plastic bottle manufacturing industry, blow molding is the most mainstream production process. Blow molding molds can quickly turn plastic raw materials into plastic bottles, and have advantages such as fast molding, short process and good molding effect. The sprue of the mold refers to the feed channel in the molding process.

[0003] However, there are still some defects in the sprue of the blow molding mold during the production process. During processing, the sprue is prone to falling onto the mold and blocking the bottle mouth. When the blow needle is inserted into the bottle mouth, it will also insert the sprue into the bottle mouth, resulting in defective parts.

[0004] A novel mold gate scraper structure is proposed to solve the above problems. Utility Model Content

[0014] (1) By setting up arc-shaped baffles and mounting grooves, two sets of arc-shaped baffles are installed in the mounting grooves opened inside the mounting port of the structure. During production, the arc-shaped baffles block the sides of the sprue, which can effectively prevent the sprue from falling onto the mold bottle mouth, and prevent failure when the blow needle is inserted, so as to ensure the normal operation of blow molding, reduce the probability of defective parts, and achieve effective support for the sprue.

The ejector spring inside the cavity can push out the positioning block through the movable plate, so that the positioning block is inserted into the inside of the positioning slot and engages with the positioning slot, which can position the arc-shaped baffle. During disassembly, the arc-shaped baffle is pulled directly and squeezed, and the positioning block retracts into the inside of the cavity, which can remove the arc-shaped baffle from the inside of the mounting slot, thus achieving convenient disassembly and assembly.

[0016] (3) By setting up an arc-shaped baffle, a connecting sleeve, a groove, a fixing spring, a fixing block, a side groove, a fixing slot and a fixing pressure plate, the two sets of arc-shaped baffles are first attached together before installation. Then, the two sets of connecting sleeves are inserted into the grooves at both ends respectively. Then, the fixing spring inside the side groove rebounds and pushes out the fixing pressure plate, so that the fixing pressure plate is engaged with the fixing slot. The connecting sleeve can be positioned through the fixing slot, and the two sets of arc-shaped baffles can be connected through the connecting sleeve, which makes it easy to splice the support structure.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during installation, the two sets of arc-shaped baffles 2 are spliced ​​together and inserted into the interior of the mounting groove 16. The ejector spring 8 inside the cavity 3 can push out the positioning block 6 through the movable plate 4, so that the positioning block 6 is inserted into the interior of the positioning slot 5 and engages with the positioning slot 5, which can position the arc-shaped baffle 2. During disassembly, the arc-shaped baffle 2 is pulled directly and squeezed, after which the positioning block 6 retracts into the interior of the cavity 3, and the arc-shaped baffle 2 can be removed from the interior of the mounting groove 16, which realizes convenient disassembly and assembly.

[0030] The arc-shaped baffle 2 has grooves 10 at both ends. A fixing block 12 is fixedly connected to one side of one end of the groove 10.

Afterward, the fixing spring 11 inside the side groove 13 rebounds and pushes out the fixing pressure plate 15, so that the fixing pressure plate 15 engages with the fixing slot 14. The connecting sleeve 9 can be positioned through the fixing slot 14, thereby connecting the two sets of arc-shaped baffles 2 through the connecting sleeve 9. During installation, the two sets of arc-shaped baffles 2 are spliced ​​together and inserted into the installation groove 16. The ejection spring 8 inside the cavity 3 can be positioned by the movable plate 4.
