Description

TECHNICAL FIELD

[0001] The utility model belongs to foundry technology field, concretely relates to a kind of polystyrene foam plastic benzene board model hoist device. BACKGROUND

[0002] At present, casting production is mostly according to user design requirements, first appearance model and internal core box are made, after being made, model is buried with prepared sand, after sand solidification, model is lifted out.General model is mostly made of wood, but the cost is relatively high to produce one to two products with wood, and the cycle is long.Therefore, for the production of 1-2 products, most foundries use polystyrene foam plastic benzene board to make model, which not only has low cost but also short cycle.But polystyrene foam plastic benzene board model lifting is troublesome, needs to be destroyed slowly, and polystyrene foam plastic benzene board is seriously damaged, cannot be recycled.Therefore, it is necessary to design a polystyrene foam plastic benzene board model hoist device to improve lifting speed, and polystyrene foam plastic benzene board model is basically not damaged, can be recycled. SUMMARY

[0003] The utility model aims at providing a kind of polystyrene foam plastic benzene board model hoist device to better improve lifting effect, improve lifting speed, and avoid damaging polystyrene foam plastic benzene board model, realize recycling.

[0004] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows.

[0005] A kind of polystyrene foam plastic benzene board model hoist device, including bottom plate, bottom plate upper surface middle part is fixed with lower hoist rod, lower hoist rod top is equipped with adjusting sleeve, adjusting sleeve top is equipped with upper hoist rod, and upper hoist rod top is fixed with lifting plate using nut.

[0006] Further, retractable bottom plate is arranged in the channel of the left and right sides of the bottom plate, and the four corners of the channel surface of the left and right sides of the bottom plate are fixed with fixing bolts.

[0007] Further, lifting ring is fixed on both sides of the lifting plate.

[0008] Further, the surface area of the bottom plate is greater than or equal to the surface area of the lifting plate.

[0009] The utility model discloses the beneficial effect lies in: the utility model device is through being equipped with slide and screw hole at bottom plate, and installing telescopic bottom plate on bottom plate, and according to model size adjustment telescopic bottom plate, then with fixed bolt fastening. And lower lifting pole bottom is installed on bottom plate, and adjustment sleeve is installed on lower lifting pole upper portion, and upper lifting pole is installed again on the inside of adjustment sleeve upper portion, adjusts height, and puts polystyrene foam plastic benzene board model, and uses nut to fix the lifting plate on upper lifting pole. After sand mould is made, needs to lift polystyrene foam plastic benzene board model, and steel wire rope is worn on the lifting ring, and can be lifted by headstock crane. The device can effectively realize the lifting of polystyrene foam plastic benzene board model, and conveniently improve efficiency, speed up the sample speed, and do not damage polystyrene foam plastic benzene board model, realize recycling, and utilization efficiency is high. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is the device structure schematic diagram used in the embodiment of the utility model.

[0011] Marked in the drawing: 1, bottom plate;2, telescopic bottom plate;3, fixed bolt;4, lower lifting pole;5, adjustment sleeve;6, upper lifting pole;7, lifting plate;8, lifting ring. DETAILED DESCRIPTION

[0012] The specific implementation of the utility model is described below in combination with the drawings, so that the utility model can be better understood.
