[0038] Working principle:

[0039] In the actual design process of the utility model, in order to avoid the following defects existing in the prior art: "in the prior art, the blow molding mold adopts the mode of butt joint of two half molds to realize the blow molding. However, the following defects exist in this mode of clamping: 1, the half mold is generally made of metal material, and the carrying burden is too heavy in the process of clamping, and the alignment positioning deviation problem is prone to occur. 2, the existing blow molding mold adopts the mode of unilateral blow molding, so that the blow molding efficiency is low, and improvement is needed. "The blow type self-opening and closing assembly 2 and the scraper assembly 3 are proposed;

[0040] The blow type self-opening and closing assembly 2:

[0041] The component is divided into two innovative parts, which are the blow structure and the self-opening and closing structure. The blow structure is the first blow port 11 and the second blow port 12 erected on both sides of the lower mold cavity 5, which realizes the blow from the two blow ports in the process of blow molding, thereby accelerating the blow molding efficiency. In order to solve the problem of difficult butt joint of the half mold in the prior art, the electromagnetic guide rod 7, the electromagnetic sliding block 8 and the electromagnetic guide rail 9 are arranged at the butt joint part of the upper mold and the lower mold, and the electromagnetic sliding block 8 is directly connected to the surface of the upper mold 6 to realize the control effect. The electromagnetic sliding block 8 is positioned and slid on the surface of the electromagnetic guide rod 7, so that the upper mold 6 can be perfectly connected to the surface of the lower mold 4, and the stable butt joint positioning effect between the upper mold and the lower mold is realized. In order to realize the movement, the support plate 10 is connected and fixed between the tray 1 and the lower mold 4.

[0042] The scraper assembly 3:

[0043] The main function of the scraper assembly 3 is to scrape the plastic residues attached to the joint between the upper and lower molds. The transmission of the scraper 13 is realized by the transmission wheels 14 arranged on both sides of the scraper 13. The transmission effect of the transmission wheels 14 is realized by the driver 16 arranged on one side of the outer box 15, and the transmission effect of the scraper 13 is realized. The scraper 13 realizes the scraping effect of the plastic residues between the molds during the reciprocating movement. The rod 18 is used to realize the positioning and fixing of the transmission components on both sides, and the mounting plate 19 is used to realize the fixing effect at the bottom.

[0044] By setting the blow-molding self-opening and closing assembly, the assembly is provided with blow-molding openings on both sides of the mold cavity, and the efficiency of blow molding is accelerated by the way of blow-molding on both sides. In addition, the device changes the traditional way of combining the two half molds, and the upper cover is combined on the surface of the lower cover by the electromagnetic guide rail, which simplifies the carrying process and increases the positioning accuracy. By setting the scraper assembly, the scraper is driven to move transversely and reciprocally by the friction wheel at the position where the plastic impurities are easily generated at the joint between the upper and lower molds, thereby realizing the scraping effect of the attached plastic and avoiding the difficulty of blow molding caused by the long-time attachment of the plastic.
