Abstract

The invention belongs to a hot-forming mould for a friction material, which comprises two parts, namely a mould frame and a module. The hot-forming mould is characterized in that a left upright plate (1), a right upright plate (3), a rear side plate (4) and a front side plate (5) are embedded and combined, thereby forming the mould frame; key slots (12) are formed inside the left upright plate (1) and the right upright plate (3) along a longitudinal direction; guiding keys (6) are mounted on the key slots (12); the module comprises a concave mould (7), a convex mould (8) and a limiting plate (9); key slots which are same as the key slots on the slide plates of the mould frame are formed on two sides of the concave mould (7) along the longitudinal direction; the module is moved into the mould frame along the guiding keys (6) and is positioned; a plurality of cavities are formed in the concave mould (7); the limiting plate (9), an inner hole dimension of which is less than the dimension of the cavities, is arranged at the bottom of the cavities; an outline dimension of the upper end of the convex mould (8) is as same as the dimension of the cavities while an outline dimension of the lower end is less than the dimension of the cavities; and the lower end of the convex mould (8) can pass through the limiting plate (9) but the upper end is limited by the limiting plate (9), thereby preventing the convex mould from falling out of the cavities. The hot-forming mould is simple in structure and low in manufacturing cost.

Description

A kind of friction material heat pressing and molding mold

Technical field

The invention belongs to the friction material heat pressing and molding mold, heat pressing and molding mold of particularly a kind of disc brake pad friction material of on the multicylinder hydraulic machine, using.

Background technology

Chinese patent " a kind of multicylinder hydraulic machine and composite set thereof " is to adopt that spring envelope mould, guide pillar, mould are extensible, a plurality of oil cylinders parallel connections are arranged or join string on station and suppress a plurality of products, compact conformation simultaneously (ZL200920094282.0).Because the particularity of press structure has determined the mould also different from the past to the requirement of the mould supporting with it.

Heat pressing and molding mold of disc brake pad friction material in the past, mainly by the die cavity body, parts such as core rod are formed.The die cavity body is a block plate, has a plurality of die cavities on it, and is installed on the workbench of press.This type mould, a kind of product just need the die cavity body of a correspondence, and appearance and size is big, and processing cost is high, change inconvenience.

This class formation mould obviously is not suitable for the multicylinder hydraulic machine.

Summary of the invention

The purpose of this invention is to provide heat pressing and molding mold of a kind of disc brake pad friction material of on the multicylinder hydraulic machine, using, the handling ease cost is low, easy installation and removal.

Accompanying drawings is following:

A kind of friction material heat pressing and molding mold is made up of framed and module two parts, and described framed by left riser 1, right riser 3, back side panel 4, the embedded aggregate erection of front side board 5 plates, left riser 1 inboard, right riser 3 inboards longitudinally all have keyway 12; Feather key 6 is housed on it, and described module is made up of die 7, punch 8, limiting plate 9, and die 7 longitudinally both sides also has the keyway identical with framed side plate; Module moves into framed and the location along feather key 6; Have a plurality of die cavities in the die 7, hole dimension was less than the limiting plate 9 of cavity dimension in cavity bottom was equipped with, and punch 8 upper end appearance and sizes are identical with die cavity; Lower end appearance and size is less than cavity dimension; Limiting plate 9 can be passed through in the lower end, and the limited plate in upper end 9 is spacing, prevents that punch from coming off from die cavity.

The described framed middle riser 2 that also comprises, left riser 1, middle riser 2, right riser 3, back side panel 4, front side board 5 be totally five embedded being combined into of plate " day " font, in two chambeies that middle riser 2 separates a set of modules is housed respectively.

Described left riser 1, middle riser 2, right riser 3 in framed longitudinally is equipped with heating tube or heating tape, also heating tube or heating tape can be installed in punch 8 bodies.

The invention has the beneficial effects as follows:

Five blocks of framed plates are processed separately, and embedded combination is simple in structure, low cost of manufacture; Framed highly versatile, the module that multiple product can be installed; Module can be clamped by framed fitting tightly with reliable location, and heat transfer efficiency is high; It is convenient and swift that the feather key structure is changed module, guarantees installation accuracy easily.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:

A kind of friction material heat pressing and molding mold is made up of with module two parts framed; Described framed by left riser 1, middle riser 2, right riser 3 and front side board 5, back side panel 4 totally five blocks of plates be combined into " day " font through embedded the connection, in two chambeies that middle riser 2 separates a set of modules is housed respectively.Left side riser 1 right flank, middle riser 2 two sides, right riser 3 left surfaces longitudinally all have identical keyway 12 on the equal height direction, feather key 6 is housed in the keyway 12, and module is packed into framed along this guiding.Left side riser, right riser and middle riser front and back end all have a groove 13, back side panel 4 and front side board 5, and the two ends protrusion, middle upper and lower sides has notch, and its position is corresponding with the groove of left, center, right riser, embedded installation.Middle riser links to each other with forward and backward side plate through screw, and left and right riser links to each other with the front and back side plate through screw.Left side riser 1, middle riser 2, right riser 3 longitudinally all are equipped with heating tube and are used for framed heating, and pass to die 7.

Described module is made up of die 7, punch 8, limiting plate 9.Die 7 is a cuboid, and with height such as framed height grade, the die both sides have and the identical keyway in framed riser side along its length, and it is highly also identical, die can along feather key 6 insert framed in.According to product size, have a plurality of die cavities in the die, hole dimension prevented that less than the limiting plate 9 of cavity dimension punch 8 from coming off from die cavity in be equipped with the die bottom.Punch 8 upper end appearance and sizes are identical with die cavity, and lower end appearance and size is less than cavity dimension, and limiting plate can be passed through in the lower end, and the limited plate in upper end is spacing, prevents that punch from coming off from die cavity, in the punch heating tube can be installed vertically, improve the mold heated effect.

When module is installed, if with module along framed feather key 6 push framed in, more framed front side board 5 usefulness screws are connected with middle riser 2, with the clamping of module front and back, left side plate inwardly clamps through screw, module and left, center, right riser is fitted tightly compress.Dismounting is during module, as long as framed front side board is pulled down, module is pulled out from framed gets final product.

During work, bulk cargo is packed in the concave die cavity, put brake block backboard 10 and upper cover plate 11, move on the mould, upper cover plate contact also compacted with the fixing entablature of press, moves in punch 8 continuation and pressurizes, and bulk cargo is pressed into blank.Mould moves down then, and blank is ejected by ejecting mechanism.
