Problems solved by technology

For some complex products, the number of inserts is as many as hundreds, and the rotational molding mold is also relatively complicated; and in the process of processing rotational molding products, multiple people are required to install and remove the inserts at the same time, and it still takes a lot of time
Excessive time for mold removal will affect the shrinkage of the product, and for products with strict requirements, the qualified rate of the product will be reduced

Embodiment 1

[0026] Such as Figure 2 to Figure 4 As shown, the rotomolding mold includes a template 1, and the template 1 surrounds a mold cavity. This rotomolding mold is suitable for producing products with inserts 10. The rotomolding mold also includes bolts 2 for fixing the inserts 10. There are bolt holes 3 on the template 1. The head 2a of the bolt 2 is located outside the template 1. The bolts The screw part 2b of 2 can penetrate into the mold cavity from the bolt hole 3. A nut 5 is threaded on the screw part 2b of the bolt 2, and the nut 5 is located outside the formwork 1, and the nut 5 and the formwork 1 are fixedly connected by welding; the head 2a of the bolt 2 can abut against the nut 5.

[0027] A washer 4 is provided between the head 2 a of the bolt 2 and the nut 5 , and the washer 4 is sheathed on the screw portion 2 b of the bolt 2 .

[0028] The usage strategy of the rotomolding mold includes a method of installing the insert 10 and a method of dismounting the insert 1...

Embodiment 2

[0032] Such as Figure 5 to Figure 8 As shown, the rotomolding mold includes a template 1 and a bolt 2, the template 1 is provided with a bolt hole 3, the head 2a of the bolt 2 is located outside the template 1, and the screw part 2b of the bolt 2 can pass through the bolt hole 3; the bolt 2 The screw part 2b is sheathed with an outer sleeve 6 and threaded with a nut 5 , and both the nut 5 and the outer sleeve 6 are located on the outside of the formwork 1 . The outer sleeve 6 is a hexagonal tube, and the nut 5 is located in the outer sleeve 6, thus avoiding the circumferential rotation between the nut 5 and the outer sleeve 6, and the nut 5 and the outer sleeve 6 are then fixedly connected by screws 7 or welded. One end of the outer casing 6 is fixedly connected with the template 1 by welding, and the head 2 a of the bolt 2 can abut against the other end surface of the outer casing 6 .

[0033] The screw portion 2b of the bolt 2 is provided with an open retaining ring 8, and...

Abstract

The invention provides a rotational mold and a use strategy of the same, and belongs to the technical field of operation. The problems that the production efficiency is low and the product yield is low when a conventional rotational mold is provided with multiple inserts are solved. The rotational mold comprises a mold plate and a bolt, wherein a bolted hole is formed in the mold plate; the head of the bolt is positioned on the outer side of the mold plate; a screw rod part of the bolt can penetrate through the bolted hole; a nut is in threaded connection with the screw rod part of the bolt; the nut is positioned on the outer side of the mold plate and is fixedly connected with the mold plate; and the head of the bolt can be pressed against the nut. According to the rotational mold and the use strategy of the same, disclosed by the invention, the inserts in products can be rapid to mount and detach, the operations such as mounting and detaching the inserts can be finished by a single person, the bolt can be screwed by adopting a pneumatic wrench, labor force and cost can be effectively reduced, the insert mounting and detaching speed is increased, the production efficiency of the product is further effectively improved, the production cost is reduced, and the yield of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of operations, and relates to a plastic processing mold, in particular to a rotational molding mold. [0002] The invention belongs to the field of operation technology, and relates to a plastic processing mold, in particular to a use strategy of a rolling mold. Background technique [0003] The rotomolding process is a thermoplastic hollow molding method. Compared with the blow molding process and the injection molding process, the rotomolding process can easily produce hollow plastic products of different sizes within a limited cost range; with the advancement of the rotomolding process , There are more and more products manufactured by rotational molding process. There are many relevant documents about the rotational molding process, such as the patent document Rotationalmoldingmachine (publication number: US4767299A); a new type of rotational molding mold (publication number: CN102814904A). [0004] So...
