Abstract
The utility model discloses a figuration lath for a lost foam casting foam-plastic mold. The figuration lath comprises a body which exerts the function of supporting and figuration, wherein the body is the lath which is made of light metal alloy, and a heat-resistant layer which is formed by pressing refractory fibers and has the same width as that of the lath is adhered on the lath. The lath is in a hollow structure. The figuration lath is used for the figuration prior to the brush coating of the lost foam casting foam-plastic mold and also serves as a support in the process of brush coating or baking, so that the problem of deformation in the process of brush coating and baking is effectively avoided, furthermore, the polishing amount for rough castings and the labor intensity for workers are greatly reduced, and the influence on the quality of the castings caused by using other materials for carrying out figuration on the part is reduced.
Description
Technical field
The utility model belongs to the lost foam casting technical field, is specifically related to typing and backing material before a kind of lost foam casting bubble moulding model is brushed.
Background technology
The normal defectiveness of lost foam casting is more, and wherein problem on deformation is consistent is that central thin-wall part of the outstanding problem that exists in the lost foam casting, particularly auto parts and components and the distortion of multi-cavity body spare are particularly outstanding.For preventing distortion, manufacturing enterprise has all taked the setting measure in various degree before bubbles model is brushed, but the setting material category of using is also more, adopts dried batten mostly; Flat iron bar, or on model sticking cystosepiment etc., the problem of appearance is: batten is rinsed drying course self-deformation pulling model deformation repeating to be coated with; Particularly little thin-wall part band iron proportion is too big, be not easy after model is bonding to place, and long band iron uses back cleaning difficulty; Slice off the back and shorten, all can not use several times by long, more than two kinds a pimple appears at the foundry goods bonding location; The polishing amount is big, and the material at batten position is hard partially, influence processing and casting quality.Cystosepiment setting has reduced the molten iron utilization rate, has increased the coating consumption, and the casting cleaning lath fracture of laying also will carry out a large amount of polishings and handle, moreover itself can not serve as holder in drying course in addition.
Summary of the invention
For solving the above-mentioned defective that prior art exists; The purpose of the utility model is to provide a kind of lost foam casting model setting lath; This setting lath is not from yielding in repeating to be coated with in rinsing and drying; And can reuse; Not only save also environmental protection of producing cost, not only play the setting effect after the setting, and serve as the support and the rebasing thing of drying engineering; Water the blank that casts out and do not stay pimple, reduce the polishing amount.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: this lost foam casting bubble moulding model setting lath; Had the body that supports the setting effect; It is characterized in that: said body is the lath that light metal alloy is made, be bonded with on the said lath refractory fibre pressing form with lath with wide refractory layer.
Said lath is a hollow structure.
Adopt the beneficial effect of technique scheme: this lost foam casting bubble moulding model setting lath is a composite slats; Be that base portion is the hollow lath of the certain specification of light metal alloy making; Appendage for the refractory fibre pressing form with lath with wide refractory layer; Two parts are bonded, and the setting lath can be arranged to plurality of specifications (size) as required.Utilize the utility model typing lath, can effectively solve the shortcoming of prior art, himself shape does not receive repeating to soak into oven dry and influencing of water; Be used for the setting before the mold of lost foam casting bubble is brushed, also can serve as the strong point of drying course after the setting, can be owing to it makes casting deformation; Cast does not stay big iron pimple, only is the vestige of melten gel, behind foundry goods casting mould turnover, can this material recovery be cleaned recycling; If attached refractory fibre partly has damage, can change in using repeatedly, reduce producing cost refractory layer; And improved the material at bonding setting position, improved production efficiency and product qualified rate.This material also served as rinse be coated with or drying course in supporter; Prevent to be coated with the problem on deformation of rinsing in the drying course effectively; And reduce the polishing amount and the working strength of workers of bad foundry goods of hair greatly, improved at this position with the influence of other materials setting to castings material.
Description of drawings
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Lost foam casting bubble moulding model setting lath as shown in Figure 1; Had the body 1 that supports the setting effect; The lath that said body 1 is made for light metal alloy; For the said lath of weight reduction adopts hollow structure, the setting lath can be arranged to plurality of specifications (size) according to the size and the structure of institute's casting.Be bonded with the refractory layer 2 that certain thickness refractory fibre pressing forms on the said lath.Refractory layer 2 is bonded into integral body with body 1 melten gel, and refractory layer 2 is identical with the lath width of body 1, if attached refractory fibre partly has damage; Can change refractory layer; Reduce producing cost, and improved the material at bonding setting position, improved production efficiency and product qualified rate.
Claims (2)
1. lost foam casting bubble moulding model setting lath has had the body that supports the setting effect, and it is characterized in that: said body is the lath of light metal alloy making, be bonded with on the said lath refractory fibre pressing form with lath with wide refractory layer.
2. lost foam casting bubble moulding model setting lath according to claim 1, it is characterized in that: said lath is a hollow structure.
