On.
A method of outer hood being produced using above-mentioned outer hood curing forming mold, is included the following steps：
(1) glue is cut：Raw rubber is cut first, is cut into the material block of predetermined weight；
(2) it plasticates：The raw rubber cut is put into banburying chamber, is plasticated, then pours out sizing material from mixer, is being opened
It is thin twice logical in length and breadth in mill, the lower volume at standard weights；
(3) it is kneaded：The raw rubber plasticated is put into mixing in mixer, then auxiliary agent is launched into mixer in batches, is mixed
Refine 5-10min；
(4) add agent：Open mill is opened, between the rubber compound of mixer discharge is put into two roller of open mill, moulding packet roller, glue
After expecting packet roller, accelerating agent and sulphur are added, after accelerating agent and sulphur are suffered all, roll spacing is turned down, sizing material is beaten into triangle bag twice,
It is thin in length and breadth again to lead to twice, then at least for 24 hours by bin aging；
(5) heat refining：Rubber compound cuts into the material strip of normal width after open mill heat refining is uniform；
(6) injection sulfurization is molded：First cope plate and lower template are molded before vulcanization, preheated, it, will be hot after the completion of preheating
The sizing material refined by machine injection to die cavity, vulcanizing 20-50min at a temperature of 150 DEG C -160 DEG C, under 220-230bar,
170-180 DEG C, pressure reduction to 200-220bar are raised the temperature to again, vulcanize 10-20min, rear mold die sinking is completed in vulcanization,
Hydraulic device jacks up cope plate, and product invests on cope plate, product is taken down；
(7) deburring：Finished product after sulfidization molding is first parked, and deburring arrangement is carried out after being cooled to room temperature；
(8) it polishes：The upper surface sprayed to it carries out surface polishing；
(9) it sprays：Surface cleaning is carried out to product spray-coating surface again before being sprayed, automatic spraying machine is opened, by product
It is put into conveyer belt, to product into spraying operation；
(10) it dries.
Further, in step (6) the injection sulfurization molding, the sizing material amount injected in die cavity is more than mold cavity volume.
Compared with prior art, the beneficial effects of the invention are as follows：
1, the present invention is facilitated by temperature detect switch (TDS) by using the real-time temperature sensor of inductive probe and carries out control heating tube
Heating temperature, it is easy to adjust；
2, it is injected in the die cavity between cope plate and lower template simultaneously using 12 groups of injection nozzles, ensures that sizing material can be with the
One time injected uniformly in die cavity；
3, the Universal wheel structure by being arranged on the substrate of bottom of device so that device conveniently moving utilizes tumbler
Control turntable can rotate so that for the die device on turntable after the completion of injection, turntable provides rotatory force, can accelerate die cavity
Interior sizing material flowing so that sizing material improves the quality of production product well into die cavity；
4, surplus chamber is set above die cavity, the sizing material amount injected in die cavity is slightly larger than mold cavity volume, avoids due to vulcanization
Product edge defect caused by retraction etc. in the process.And surplus chamber is arranged on cope plate, is on the one hand convenient for redundant rubber stock
Storage, when being also convenient for the reflux of sizing material, and molding, the sizing material in surplus chamber links together with product, need not be to surplus
Chamber carries out special cleaning；
5, curing temperature and pressure use two section type, begin with cryogenic high pressure and are vulcanized, rubber molecular chain is made to exist
It is slowly crosslinked under low temperature, strand is formed compared with long-chain branch, the high mechanical strength of sizing material, and the excessively high cross-bond of premature cure temperature is formed
Short-chain branch reduces the mechanical performance of sizing material.Cryogenic vulcanization for a period of time after, the excessive gas in sizing material has been discharged, it is internal
Part forms cross-linked network, then is vulcanized using high-temperature low-pressure, not only shortens vulcanization time, moreover it is possible to improve the various aspects of product
Energy.
