Description

Technical Field

[0001] The present invention relates to the field of mold technology, and more specifically, to a vulcanization mold rapid heating process method and system. Background Art

[0002] Vulcanization, also known as cross-linking and aging, is a process in which cross-linking aids such as vulcanizers and accelerators are added to rubber to transform linear macromolecules into three-dimensional network structures under certain temperature and pressure conditions. Since sulfur was first used to achieve cross-linking of natural rubber, it is called vulcanization. When vulcanizing to form a product, a mold needs to be used and heated. During heating, the mold needs to be heated from room temperature to a vulcanization temperature of ≥150°C. The existing technology often uses upper and lower heating plates of the vulcanizer for upper and lower heating. The heating process often takes 2 to 3 hours, and the heating time is long, and the vulcanization efficiency is relatively low.

[0003] The patent application for the invention of a hybrid heating tire vulcanizer with the publication number CN113650207A and the patent name is a hybrid heating tire vulcanizer. The background technology of the patent application mentions that the vulcanization heating of rubber products in the prior art usually uses the upper and lower heating plates of the vulcanizer to heat the mold, and the upper and lower heating plates play the role of heating and heat preservation. The patent takes into account the heating efficiency problem, and an oil storage cavity is opened inside the lower mold, that is, the lower mold is a hollow structure, and an oil inlet hole and an oil outlet hole are respectively opened on the lower mold. The oil storage cavity is connected to the inner cavity of the center tube through the oil inlet hole and the oil outlet hole, and the center tube is sleeved with an oil pipe. During vulcanization heating, the oil pipe passes heat transfer oil into the center tube, and the heat transfer oil enters the lower mold through the oil inlet hole and the oil outlet hole to heat the tire embryo, and the heating plate in the upper mold is heated at the same time. The heat transfer oil can heat the lower mold to increase the temperature, so that the tire embryo quickly reaches the vulcanization temperature and the heating plate can continue to heat the mold. The combination of the two makes the mold quickly heat up to reach the reaction temperature of the tire embryo. On the other hand, the heating plate can keep the mold warm continuously to ensure the reaction temperature of vulcanization. From the description in its embodiment, the patent uses oil storage cavity heating to replace the lower heating plate heating. After heating to the set temperature, the upper heating plate keeps the mold warm.

[0004] The above patents involve tires and are used in the tire field. This application involves rubber-metal elastic bearings, which are used in the field of elastic vibration damping products. The two products belong to different fields. The structure of rubber-metal elastic bearings is much more complicated than that of tires, and the mold self-heating is also more complicated. The above patents only heat the lower mold. When used to produce rubber-metal elastic bearings, there will be technical problems such as uneven heating, slow temperature rise, and low vulcanization efficiency. Summary of the invention

The upper heating plate 1 and the lower heating plate 2 are generally heated by heating rods. This heating method takes 2 to 3 hours to heat up to the set temperature, which is too inefficient. The present application provides a vulcanization mold heating process method and a rapid heating vulcanization mold system, which are as follows: A method for rapidly heating up a vulcanization mold comprises the following steps: uniformly arranging interconnected pipelines 4 in a mold 3, arranging a heat source system A to introduce a heat-conducting medium into the pipelines 4; simultaneously turning on an upper heating plate 1 and a lower heating plate 2 of a vulcanizer to heat the upper and lower surfaces of the mold 3, and synchronously achieving rapid heating of the mold 3 from top to bottom and from inside to outside; arranging a temperature sensor in the mold 3 to send a temperature signal to a control system in real time, and the control system controls the heat-conducting medium to circulate in the heat source system A for heating or cooling, and ensuring that the temperature in the mold 3 is maintained at a set temperature.

[0022] The "simultaneous rapid heating of the mold top and bottom and from the inside to the outside" mentioned in the present application means that the upper heating plate 1 and the lower heating plate 2 heat the mold 3 top and bottom, and at the same time, the pipeline 4 inside the mold 3 connected to the heat source system A heats the inside of the mold 3, and the heat is transferred from the inside to the outside, so that the entire mold 3 is heated rapidly.

[0023] In order to realize the above-mentioned vulcanization mold rapid heating process method, the present application also provides a rapid heating vulcanization mold system, such as Figure 1 As shown, it includes a vulcanizer and a mold 3, the vulcanizer includes an upper heating plate 1 and a lower heating plate 2, the upper heating plate 1 and the lower heating plate 2 are respectively located above and below the mold 3; it also includes a heat source system A and a control system, and interconnected pipelines 4 are evenly arranged in the mold 3; the pipeline 4 includes an inlet 24 and an outlet 25, and the heat source system A is respectively connected to the inlet 24 and the outlet 25 of the pipeline 4; the heat source system A passes a heat-conducting medium into the pipeline 4; the mold 3 is also provided with a temperature sensor, the temperature sensor sends temperature information of the heat-conducting medium passed into the pipeline 4 to the control system, and the control system controls the heat source system A to heat or cool the heat-conducting medium.

[0024] The heat conducting medium in this embodiment is a liquid, such as Figure 4As shown, the heat source system A includes a hot oil pipeline system, a cold oil pipeline system, a three-way valve 15, hot and cold oil outlets 6 and hot and cold oil return ports 7.

[0025] like Figure 4 As shown, the hot oil storage tank 8 and the cold oil storage tank 12 are also connected to a replenishing oil tank respectively, which are called hot replenishing oil tank 16 and cold replenishing oil tank 17 respectively, and the hot replenishing oil tank 16 and the cold replenishing oil tank 17 are connected through a pipeline; two valves 18 are also installed on the pipeline, and a pipeline 4 is connected between the two valves 18 and is connected to the hot and cold oil return ports 7; the hot replenishing oil tank 16 and the hot oil storage tank 8 are connected to an oil replenishing pipeline 19 and an exhaust pipeline 20; the cold replenishing oil tank 17 and the cold oil storage tank 12 are also connected to an oil replenishing pipeline 21 and an exhaust pipeline 22.

[0026] like Figure 2 , 3 As shown, the mold 3 has four sides, and the specific structure of the pipeline 4 in the mold 3 is: the two opposite faces are penetrated by the pipeline 4, and the other pair of opposite faces are also penetrated by the pipeline 4, and the pipelines 4 in two directions are perpendicular to each other and connected; the pipelines 4 that do not serve as the inlet 24 and the outlet 25 are blocked with a copper cone plug 23, and the pipelines 4 that serve as the inlet 24 and the outlet 25 are connected to the heat source system A.

[0027] like Figure 5 As shown, multiple rows of pipelines 4 are opened on the side of the mold 3, so that the pipelines 4 form a multi-layer structure.

[0028] like Figure 1As shown, the heat source system A in this embodiment is connected to the mold 3 with four inlets and four outlets, that is, there are four inlets 24 and four outlets 25 on the mold 3, the four inlets 24 are connected to the cold and hot oil outlets 6, and the four outlets 25 are connected to the cold and hot oil return ports 7.

[0029] The heat exchanger 14 is a plate exchanger.

[0030] The three-way valve 1 5 , the three-way valve 2 11 and the three-way valve 3 15 are all electric three-way valves.

[0031] The hot oil pump 9 and the cold oil pump 13 are both variable displacement pumps.

[0032] In this embodiment, the heat source system A and the mold 3 to be heated are connected by a 2-inch corrugated pipe with four inlets and four outlets. When the signal is received to start heating, the heating pipe 10 first heats the heat-conducting medium. After the hot oil pump 9 is started, the heat-conducting medium is quickly circulated to exchange heat with the mold 3. The temperature sensor installed on the mold 3 controls the temperature and flow of the heat-conducting medium through the three-way valve 1 5, the three-way valve 2 11 and the three-way valve 3 15, so as to achieve the rapid heating and constant temperature of the mold 3 and meet the temperature control accuracy requirements. When the temperature of the mold 3 reaches the preset temperature, the heat-conducting medium is internally circulated, the heating pipe stops heating, and the hot oil pump 9 stops working. When the temperature control temperature deviation on the mold 3 is -1°C, the above heating process is repeated. If the temperature deviation is +1°C, the compressor of the cold oil pump 13 starts the cooling mode, the cold oil pump 13 is turned on, and the heat-conducting medium is cooled through the plate exchanger. The temperature sensor of the mold 3 is linked to the electric three-way valve for electric control, so that the temperature of the mold 3 meets ±1°C.

A temperature sensor is installed in the middle of the mold 3. The rapid heating process method controls the temperature of the mold 3 by linking the temperature control sensor of the mold 3 with a variable pump. The flow rate of the high-temperature synthetic heat-conducting medium is adjusted according to the deviation between the set temperature and the required temperature to achieve high-precision temperature control, effectively shortening the heating time of the mold 3 and stabilizing the mold temperature by ±1°C.

[0033] The three-way valve 5 is a three-way valve that can adjust the flow rate. The temperature sensor is installed in the middle of the mold 3. The control system is a PLC control system. According to the deviation between the actual temperature of the temperature sensor connected to the mold 3 and the set temperature, the control system automatically fine-tunes the flow rate in large proportion to ensure that the temperature of the mold 3 rises quickly and meets the high-precision temperature control requirement of ±1°C.

[0034] When heating: Figure 4As shown, the hot oil storage tank 8-hot oil pump 9-heating pipe 10-three-way valve 11-hot and cold oil outlet 6-mold 3-hot and cold oil return port 7-hot oil storage tank 8 constitutes a heat circulation loop to provide heat inside the mold 3. The hot oil tank 16 replenishes oil and exhausts the circulation system.

[0035] During heat preservation: when the set temperature is reached in the mold 3, the heat storage tank 8-heat oil pump 9-heating pipe 10-three-way valve 11-heat storage tank 8, the heat transfer medium circulates internally, the heating pipe stops heating, and the heat oil pump 9 stops working. When the temperature control temperature deviation on the mold 3 is -1°C, the above heating process is repeated. The hot oil tank 16 is used to exhaust the circulation system.

[0036] During cooling: if the temperature deviates by +1°C, that is, the temperature is higher than the set temperature, the cold oil storage tank 12-cold oil pump 13-heat exchanger 14-cold and hot oil outlet 6-mold 3-cold and hot oil return port 7-cold oil storage tank 12 forms a circulation loop to cool the inside of the mold 3. The cold oil tank 17 replenishes oil and exhausts the circulation system.

For those skilled in the art, the present invention may have various modifications and variations.
