Box foaming rocking mechanism

Abstract

The invention discloses a box foaming rocking mechanism, which comprises a rocking core-pulling block, a connecting rod mechanism and a fixing frame used for fixing the connecting rod mechanism, wherein the connecting rod mechanism comprises a connecting rod; one end of the connecting rod is connected to the fixing frame; and the rocking core-pulling block is directly connected with the other end of the connecting rod movably. The power of the box foaming rocking mechanism is from a liner of a prefabricated box, the motion of the prefabricated box directly drives the rocking core-pulling block to move, and the lifting speed of a fixture is consistent with the speed that the liner enters or is separated from a mould core; therefore, a phenomenon that the rocking core-pulling block drives the liner is avoided and the product quality is greatly improved.

Description

[0001] technical field [0002] The invention relates to a box foaming swing mechanism. Background technique [0003] When manufacturing foam molds for refrigerator boxes, the mold core generally needs to have a demoulding mechanism when foaming. The swing mechanism used for foaming and demoulding is as follows: figure 1 As shown, it mainly drives the linkage of a series of workpieces connected to it through the upward movement of the fixture, and then adjusts the swinging core-pulling block and the pre-installed box to a suitable foaming position. The working principle is roughly as follows: when After the foamed pre-packed box is placed in the fixture, the fixture starts to rise, and the friction plate 7' above the side plate 9' of the fixture is driven to rise with the roller 8', and at the same time, it drives the table rod 6' to rise, and the table rod 6' rises again. Drive the connecting plate 2', and finally the connecting plate 2' drives the swing core-pulling ...

AI Technical Summary

Problems solved by technology

The disadvantages of this swing mechanism are: (1) The power of this mechanism comes from the side plate of the fixture, which drives the movement of the table rod, and then drives the movement of the swing core block, and the linkage construction is complicated; although the rising speed of the fixture is the same as the foaming box enters The speed of the mold core is consistent (the movement of the fixture directly drives the movement of the pre-foaming box), but the movement of the pre-foaming box is inconsistent with the movement of the swinging core-pulling block, so that there will be a belt of swinging core-pulling block gallbladder phenomenon; the splicing gap between the inner tank and the side plate after foaming is large, which affects the product quality and seriously leads to the scrapping of the product; (2) There are many structural parts in this mechanism, and it is prone to failure during use; ( 3) In the production process of this mechanism, the debugging time is long, the debugging is difficult, and the quality stability is poor in the product production process; (4), the structural parts of this mechanism are many, resulting in increased costs and waste of resources; (5), this The power of the mechanism comes from the side plate of the fixture, and the load on the foaming equipment increases, resulting in energy consumption and uneconomical
