Abstract
The utility model relates to a rubber product supporting bracket; a supporting bracket (2) is in a shape of a straight strip; the bottom of the supporting bracket (2) is arranged to be flat; an opened cavity (21) is arranged in the middle of the upper part of the supporting bracket; the shape of the cavity (21) is consistent to the outline of a rubber product (1); and the supporting bracket is made of EPDM (Ethylene-Propylene-Diene Monomer). By using the supporting bracket, the stability of section of the rubber product is effectively ensured.
Description
Technical field
The utility model relates to a kind of rubber bracing frame.The continuity production line that is used for rubber.Belong to the product of rubber and plastic technical field.
Background technology
The continuity production line of rubber is made up of extruder, microwave firing box, air oven and cooling water tank.It is convenient that this production line has technological operation, yield rate height, characteristics such as production efficiency height.But because terrestrial gravitation effect (as Fig. 1) causes easily causing product section (particularly both sides) distortion in sulfidation, subside aborning, even can't be shaped, cause the product section not meet the pattern requirement, install not in placely, use problems such as unreasonable.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can make the rubber bracing frame that section in the sulfidation is indeformable, do not subside.
The purpose of this utility model is achieved in that a kind of rubber bracing frame, support frame as described above is the vertical bar shape, tabular is arranged in the bracing frame bottom, be provided with a uncovered die cavity in the middle of the bracing frame top, the shape of this die cavity is consistent with the profile of rubber product, and the material of support frame as described above adopts the EPDM(ethylene propylene diene rubber).
The beneficial effects of the utility model are:
The use of the utility model bracing frame, effectively guaranteed the stability of rubber product section, meet the requirement of drawing, cut the waste, improve qualification rate, reach the effect of getting twice the result with half the effort, draw inferences about other cases from one instance simultaneously, be applied to the typing of various complicated shapes, produce the designed ideal form of client's drawing, satisfy the close tolerance seal performance requirement of multiple cooperation.

The specific embodiment
One, the making of bracing frame
Bracing frame is the vertical bar shape, and tabular is arranged in the bracing frame bottom, is provided with a uncovered die cavity in the middle of the bracing frame top, the shape of die cavity is consistent with the profile of rubber product, during use, rubber product is extruded in this die cavity, the outer rim of rubber product and the inwall and the roof of die cavity are fitted.
The material of this bracing frame must be and don't to absorb microwave through microwave irradiation.Because the last rubber product of bracing frame is to need abundant absorption microwave just can reach sulfurizing point, and is cross-linked into stable network structure, thereby satisfies instructions for use.
This bracing frame must be flexible, can arbitrarily turn round, but can support the weight that product produces distortion fully when rubber product enters curing cage.
This bracing frame must be continuously, and is to use repeatedly, and can not the be subjected to high temperature influence of (250 ℃).
This bracing frame can not stick together with the product of made, guarantees that the outward appearance of product is not involved.
In sum, the utility model bracing frame material adopts the EPDM(ethylene propylene diene rubber), it can not influence microwave, can turn round, and and can indefinite length, repeat through high temperature and aging.So just can reach the belt-type bracing frame the condition that should possess.
Two, the design of vulcanization molding equipment extrusion neck ring mold processing
Design the keypoint part of bracing frame earlier according to the basic configuration of product, consideration is reliable and stable with combining of belt conveyor plane then, as Fig. 2.
Three, technique initialization
When using bracing frame to produce, should earlier bracing frame be sprayed anti-stick coating, prevent adhesion with rubber product, cause the open defect of product, then with bracing frame by preheating (80 ~ 120 ℃ preheating 30 minutes), elimination is expanded with heat and contract with cold and the section variation that causes, and the size qualified for product lays the first stone.
Four, make finished product
When producing, bracing frame is to enter microwave firing box and air oven etc. simultaneously with rubber product, rubber product is under bracing frame reasonably supports, microwave and hot-air have fully been absorbed, reached the cancellated high resiliency function of rubber, at last before entering cooling water tank, the rubber product that has vulcanized is realized separating with bracing frame, repeats to get back to extrude operation (cross-head) again.When producing, need to use some complementary machine equipments to safeguard stable trend, service life and the result of use of bracing frame in addition.
Claims (1)
1. rubber bracing frame, it is characterized in that: support frame as described above (2) is the vertical bar shape, tabular is arranged in bracing frame (2) bottom, be provided with a uncovered die cavity (21) in the middle of the bracing frame top, the shape of this die cavity (21) is consistent with the profile of rubber product (1), and the material of support frame as described above adopts ethylene propylene diene rubber.
