Abstract
The utility model discloses a prefoaming machine for casting by vanishing die, wherein a shell of a foaming machine is a sandwich structure with heat-conducting medium filled in the middle; a bottom plate of the shell is of a hollow porous sieve plate structure and is connected with a steam pipeline and a compressor pipeline; a variable-frequency motor is arranged on the top of the shell and is connected with a stirring device inside the shell through a reducer. The utility model makes EPS and EPMMA (copolymer) plastics prefoamed respectively on the same foaming machine, which saves equipment investment and improves foaming quality; and the utility model controls and regulates the stirring speed of the stirring device by using the variable-frequency motor, which is convenient for speed regulating observation.
Description
The utility model relates to the improvement of prefoam machine, says it is to disclose a kind of dispellable mould casting prefoam machine definitely, belongs to bubble moulding material prefoam equipment technical field.
Existing disappearance mould foaming machine has two kinds of structures usually: a kind of is steam direct-heating type structure, bubble is moulded original bead heating make its expansion, this kind equipment only limit the use of the plastics in EPS; Another kind of is the Sandwich pot structure, by the heat-conducting medium in the heating interlayer, makes bubble mould bead and adds thermal expansion, and this kind equipment is mainly used in the foaming of EPMMA or its EPS copolymer; Because above-mentioned two kinds of equipment are used for different foamed plastics, do not have versatility, therefore can not satisfy the requirement of modern production,
The utility model discloses a kind of dispellable mould casting prefoam machine, solved existing foaming machine for EPS and the plastic foamed problem that does not have versatility of EPMMA.
Technical solution of the present utility model is as follows: the housing of foaming machine is a sandwich, the centre is filled with heat-conducting medium, the chassis of housing is that the porous sieve plate structure of hollow connects with steam pipework, compressor circuit, and the top that variable-frequency motor is located at housing connects with agitating device in the shell by decelerator.
The utility model is compared with existing foaming machine has following good effect: adopt sandwich shell structure and porous ventilation sieve-plate structure, can finish two kinds of functions of direct heating and indirect, two kinds of plastics of EPS and EPMMA (copolymerization) can be sent out on same foaming machine respectively in advance, save equipment investment, improved foaming quality; Utilize variable-frequency motor control to adjust the mixing speed of agitating device agitating device, made things convenient for the speed governing observation, reduced starting current, saves energy has prolonged service life of equipment.
Fig. 1 is the utility model structure principle chart.
Further specify the utility model below in conjunction with accompanying drawing: in Fig. 1, the outside of foaming machine is a heat-insulation layer, housing 1 is made sandwich, be filled with heat-conducting medium 2 in it, as conduction oil, water and steam, by direct heating or indirect medium mode foamable machine, pressure and temperature can reach 0.2Mpa and 135 ℃ respectively; The chassis 6 of housing is connected with steam pipework 3, right compression conduit and discharge pipe line 4 respectively for hollow structure, the housing inner surface on chassis 6 is evenly distributed with some screen clothes 5 (being 4 screen clothes in the present embodiment), each screen cloth specification is 4 * 100 sieve meshes, air and steam directly enter into foaming machine by screen cloth, add thermal and mould bead; The top arrangement of housing 1 has variable-frequency motor 9, connects with agitating device 7 in the housing by decelerator 8, drives shaft and rotates, regulate variable-frequency motor control mixing speed, monitor expansion ratio easily, operation is simple and reliable, finishes the prefoam work of two kinds of bubble moulding materials with an equipment.
Claims (1)
1, a kind of dispellable mould casting prefoam machine, it is characterized in that: the body of foaming machine (10) is sandwich, the centre is filled with heat-conducting medium, the chassis (6) of body (10) is that the porous sieve plate structure of hollow connects with steam pipework (3), compressed air line (4), and the top that variable-frequency motor (9) is located at body (10) connects by the interior agitating device (7) of decelerator (8) and body (10).
