Polyurethane molding closing perfusion foaming mold base

Abstract

The invention discloses polyurethane molding foaming equipment, and in particular relates to a polyurethane molding closing perfusion foaming mold base. The polyurethane molding closing perfusion foaming mold base comprises a first mold base split body and a second mold base split body, wherein the first mold base split body comprises a lower mold base, a mold locking mechanism and an upper mold, and a height space corresponding to a lower mold is formed between the lower mold base and the upper mold; the second mold base split body comprises a ground running trolley and the lower mold; both the first mold base split body and the second mold base split body are provided with a corresponding propped face and a matched butted point arranged on the propped face; the first mold base split body and the second mold base split body are provided with combined magnetic switches on the corresponding matched butted points; and the ground running trolley is provided with a buckle corresponding to the mold locking mechanism. For overcoming the technical defect that the conventional mold base occupies a large space, the invention provides a mobile split mold base structure of the upper and lower molds.

Description

technical field [0001] The invention belongs to polyurethane molding foaming equipment, in particular to a polyurethane molding closed-mold perfusion foaming mold base. Background technique [0002] The lining of automotive interior parts is generally attached with polyurethane foam material to improve the texture, comfort and service life of automotive interior parts. In particular, heavy-duty vehicle cab carpets are generally attached with polyester foam sponge, and heavy-duty vehicle cab carpets have a relatively large area, especially the carpet for the engine cover, which is in an inverted U shape, 1300 * 1300 * 380 or more, so foaming The mold base is also very heavy, and it is impossible to manually open the mold for pouring and foaming. Generally, automatic mold bases are used for foaming, and cylinders are used to open and close the mold bases, and cylinders are used to lock the mold bases. [0003] Chinese patent CN 201800179 U discloses a kind of polyurethane mol...

AI Technical Summary

Problems solved by technology

[0004] The above technical solution has the following technical defects: Since the upper and lower mold bases have been fixed together in the space area, however, some substrates need to be heated to a molten thermoplastic state and immediately added to the lower mold for shaping, so the above-mentioned operation of inserting the substrate It must be carried out at the placement position of the entire formwork, so it is necessary to add a substrate processing device next to the formwork, so that multiple devices can be concentrated at a single position, and the space for human operation is reduced, which brings inconvenience to human operations such as inspection of the machine and observation of samples. necessary trouble
