Description

The braked wheel casting mould
Technical field
The utility model relates to a kind of casting mould, particularly a kind of braked wheel casting mould.
Background technology
The traction machine of elevator is the power-equipment of elevator, and its function is to carry with transferring power to make the elevator operation.The traction machine of elevator is made up of motor, brake, shaft coupling, reduction box, traction sheave, frame and directive wheel etc.Be provided with braked wheel in the brake, braked wheel is the vitals in the brake, requires to have that intensity is big, good toughness, performance such as wear-resistant, shock-resistant.Braked wheel obtains behind the blank blank is obtained after by machined by casting again, and existing casting typically uses sand mo(u)ld, use the sand casting braked wheel, one pair of mould can only be cast a braked wheel, the expense height, braked wheel cooling velocity during with sand casting in the casting die is slower, life cycle of the product is longer, time-consuming production efficiency is low, during production in enormous quantities owing to need to use a large amount of sand and the bigger occupied ground that needs of mold integral volume many, in addition, adopt the fine and closely woven degree of its interior tissue of braked wheel of sand casting and case hardness all to be difficult to reach higher requirement and the quality that influences braked wheel.
The utility model content
It is low, simple in structure and can guarantee the braked wheel casting mould of braked wheel quality that the purpose of this utility model provides a kind of cost.
The technical scheme that the utility model adopts for achieving the above object is: a kind of braked wheel casting mould, this casting mould comprises the punching block of moulding braked wheel outer surface, the endoporus sand mo(u)ld of the inner chamber sand mo(u)ld of moulding braked wheel inner surface and moulding braked wheel endoporus, the punching block inboard is concaved with inner chamber, the inner chamber center bottom is provided with the internal taper hole I that is communicated with inner chamber, the inner chamber sand mo(u)ld is installed in the inner chamber of punching block and is supported by punching block top end face, the outstanding location inner chamber sand mo(u)ld convex shoulder that is provided with of punching block top end face outer rim, inner chamber sand mo(u)ld middle part is provided with the internal taper hole II, the position of internal taper hole II is relative with the position of internal taper hole I, the endoporus sand mo(u)ld is installed in the internal taper hole II of the internal taper hole I of punching block and inner chamber sand mo(u)ld respectively and passes inner chamber and fuses up and down, is respectively equipped with sprue gate and rising head on the described inner chamber sand mo(u)ld.
Instructions for use according to braked wheel, the surface that brake block and braked wheel directly rubbed when the cylindrical of braked wheel was elevator brake, its case hardness is had relatively high expectations, except that friction surface, the hardness at other position is relatively low, for satisfying the needs of this property, the braked wheel casting mould of the utility model is owing to comprise that the punching block of moulding braked wheel outer surface and two sand mo(u)lds of moulding braked wheel inner surface and endoporus are combined into.After the cast, invar mould cooling is fast, and the sand mo(u)ld cooling is slow, and fast cooling cast(ing) surface hardness height is organized fine and closely wovenly, and it is low to cool off slow cast(ing) surface relative hardness.The performance requirement that just in time is fit to braked wheel guarantees the quality of braked wheel effectively.The cooling velocity of invar mould is very fast, manufacturing cycle shortens significantly, simultaneously, the braked wheel casting mould overall volume of the molded work of the original sharp sand of overall volume, weight ratio of the braked wheel casting mould that punching block and sand mo(u)ld composition are new is little, reduce the floor space of mould, punching block can reuse, and can effectively reduce manufacturing cost, in addition, this braked wheel casting mould overall structure is simple.
Description of drawings
Fig. 1 is the structural representation of braked wheel.
Fig. 2 is the punching block schematic diagram of the utility model braked wheel casting mould.
Fig. 3 is the structural representation of the utility model braked wheel casting mould and braked wheel combination.
The element numbers explanation:
The 1-braked wheel, 2-endoporus, 3-braked wheel inner chamber, 4-punching block, 5-internal taper hole I, 6-inner chamber, 7-rising head, 8-inner chamber sand mo(u)ld, 9-endoporus sand mo(u)ld, 10-internal taper hole II, 11-sprue gate, 12-punching block top end face, 13-convex shoulder.
The specific embodiment
As shown in Figure 1, braked wheel 1 comprises the endoporus 2 that is arranged on the braked wheel centre position and is arranged on endoporus 2 braked wheel inner chamber 3 on every side that sidewall and bottom surface are the braked wheel inner surface around the braked wheel inner chamber 3.
The utility model braked wheel is cast tool as shown in Figures 2 and 3, this casting mould comprises the punching block 4 of moulding braked wheel outer surface, the endoporus sand mo(u)ld 9 of the inner chamber sand mo(u)ld 8 of moulding braked wheel inner surface and moulding braked wheel endoporus, punching block 4 inboards are concaved with inner chamber 6, inner chamber 6 center bottom are provided with the internal taper hole I 5 that is communicated with inner chamber, inner chamber sand mo(u)ld 8 is installed in the inner chamber of punching block and is supported by punching block top end face 11, the outstanding location inner chamber sand mo(u)ld convex shoulder 13 that is provided with of punching block top end face 12 outer rims, inner chamber sand mo(u)ld 8 middle parts are provided with internal taper hole II 10, the position of internal taper hole II 10 is relative with the position of internal taper hole I 5, in the internal taper hole I 5 that endoporus sand mo(u)ld 9 is installed in punching block respectively and the internal taper hole II 10 of inner chamber sand mo(u)ld and pass inner chamber and fuse up and down, endoporus sand mo(u)ld 9 is located jointly by two internal taper holes, leans on the bottom support of the internal taper hole I of punching block.Be respectively equipped with sprue gate 11 and rising head 7 on the inner chamber sand mo(u)ld 8, after installing, punching block and inner chamber sand mo(u)ld and endoporus sand mo(u)ld form the cavity of cast braked wheel, sprue gate 11 is run through the inner chamber sand mo(u)ld and is communicated to cavity by the position of bottom, and rising head 7 is connected to the cavity upper end position and is communicated with cavity.
