Further, referring to fig. 2, the present utility model further provides a method for preparing a flow guide sleeve, which is used for preparing the flow guide sleeve, and the method for preparing the flow guide sleeve comprises the following steps:

step S10, mixing a first compound, a first main catalyst and a second main catalyst to obtain a first composition.

In the step S10, the reaction temperature needs to be controlled to ensure that the first composition has sufficient chemical activity, so that the first compound is prevented from being decomposed due to the excessive temperature, or the first main catalyst and the second main catalyst are prevented from being failed due to the excessive temperature, so that in this embodiment, the first compound, the first main catalyst and the second main catalyst are mixed to obtain the reaction temperature of the first composition of 20-25 ℃; specifically, during actual operation, when the first composition is prepared, the steps of sequentially weighing 85-95% of a first compound, 3-10% of a first main catalyst and 2-5% of a second main catalyst by adopting a hydraulic system according to weight percentage, putting the first compound, the first main catalyst and the second main catalyst into three metering pumps at 20-25 ℃, metering and outputting the substances through the three metering pumps, and inputting the substances into a stirring cylinder, and simultaneously stirring the raw materials while inputting the raw materials into the stirring cylinder in order to ensure the mixing of the raw materials in the inputting process, so that the first compound, the first main catalyst and the second main catalyst can be fully contacted, and the prepared first composition has full chemical activity.

Step S20, mixing a second compound, a first auxiliary catalyst and a second auxiliary catalyst to obtain a second composition;

likewise, in the step S20, the temperature is also controlled to ensure that the second composition has sufficient chemical activity, to avoid decomposition of the second compound due to an excessive temperature, or to avoid failure of the first and second sub-catalysts due to an excessive temperature, so that in this embodiment, the second compound, the first sub-catalyst, and the second sub-catalyst are mixed to obtain the second composition at a reaction temperature of 20 to 25 ℃; specifically, during actual operation, when the second composition is prepared, the steps of sequentially weighing 85-95% of the second compound, 2-8% of the first auxiliary catalyst and 3-7% of the second auxiliary catalyst by adopting a hydraulic system according to weight percentage, putting the second compound, the first auxiliary catalyst and the second auxiliary catalyst into three metering pumps at 20-25 ℃, metering and outputting the substances through the three metering pumps, and inputting the substances into a stirring cylinder, and simultaneously stirring the raw materials while inputting the raw materials into the stirring cylinder in order to ensure the mixing of the raw materials in the inputting process, so that the second compound, the first auxiliary catalyst and the second auxiliary catalyst can be fully contacted, and the prepared second composition has sufficient chemical activity.

And step S30, mixing the first composition and the second composition to obtain a mixed liquid.

If the first composition and the second composition are directly injected into the mold cavity, the first composition and the second composition are unevenly distributed, resulting in poor performance of the prepared air guide sleeve, the first composition and the second composition need to be mixed first to ensure uniformity of material distribution of the prepared air guide sleeve, during the mixing process, both the uniformity of material distribution of the first composition and the second composition need to be considered, and the first composition and the second composition need to be ensured not to undergo polymerization reaction, so that in the step S30, a low-pressure molding process is selected, specifically, during actual operation, the first composition and the second composition are injected into two injection machines at a temperature of 20-25 ℃, the pressure of the injection machines is adjusted to 10-12 MP, the flow rate is adjusted to 40-70L/min, and both the injection machines simultaneously perform the first composition and the second composition to obtain uniform distribution of the first composition and the second composition, and during the injection process, the first composition needs to be mixed and the second composition need to be uniformly mixed, and the first composition needs to be mixed and stirred and the second composition need to be uniformly mixed.

And S40, injecting the mixed material liquid into a mold, sequentially filling the mold, molding and solidifying to obtain the guide cover.

The die comprises a male die and a female die.

When the mixed material liquid is filled, the filling pressure has great influence on the flowing form of the material flow in the die cavity, the injection pressure is reasonably adjusted to ensure that the flowing state of the material flow is stable spreading flow, the filling injection pressure is set to be 0.3-0.6MPa, the filling time is 20-25s, and the whole die cavity can be quickly and stably filled with the reaction mixture; when the mixed material liquid is injected into the die cavity, the temperature of the die cavity can reach 200 ℃ at most due to the poor thermal conductivity of plastic and a large amount of reaction heat, in this case, the die needs to exchange heat and emit heat generated by polymerization reaction, so that the highest temperature of the die cavity of the die is controlled below the thermal decomposition temperature of resin, the temperature of the die cavity is rapidly reduced to the demolding temperature (namely, the temperature of the male die is 60-70 ℃ and the temperature of the female die is 70-80 ℃) for 100-180 seconds, and the curing purpose is to place the guide cover to deform after demolding, so that the mixed material liquid needs to be filled in the whole die cavity and cured and molded in the preparation process.

Further, during two preparation processes of mold filling and curing, deflection vibration of mold equipment is required to be added, and the main purpose is to prevent bubbles from occurring on the surface of the prepared guide cover, and influence the strength and rigidity of the guide cover and the surface appearance quality of the guide cover; therefore, in step S40, in order to ensure the performance of the finally prepared air guide sleeve, the deflection angle of the mold is adjusted to 45-55 ° in the mold filling and curing process, so that the mold can have a sufficient inclination angle, the air holes are easily removed, the control of the working table surface with the vibration frequency of 10-20 Hz is increased, the overflow of the internal air holes is increased, and the internal air bubbles of the finally prepared air guide sleeve are reduced, thereby integrally improving the quality of the air guide sleeve.

Specifically, in performing step S40, the following steps may be performed:

s401, injecting the mixed feed liquid into a die cavity of the die under the condition of 0.3-0.6 MPa, waiting for 20-25S, and stopping injection;

step S402, adjusting the deflection angle of the die to 45-55 degrees with the vibration frequency of 10-20 Hz, and waiting for 250-300S;

and step S403, the temperature of the male die is reduced to 60-70 ℃, the temperature of the female die is reduced to 70-80 ℃, the deflection angle of the die is adjusted to 45-55 ℃ at the vibration frequency of 10-20 Hz, and the die waits for 100-180S to obtain the guide cover.

Further, in this embodiment, the pod assembly may be obtained as follows:

(1) Mixing 95g of polydicyclopentadiene (PDCPD), 3g of tungsten chloride and 2g of tetrachlorophenol at 23 ℃ to obtain a first composition;

(2) Mixing 85g of polydicyclopentadiene (PDCPD), 8g of aluminum alkyl, and 7g of tetrachlorophenol at 23℃to obtain a second composition;

(3) Mixing the first composition and the second composition according to the volume ratio of 1:1 at 23 ℃ and 10MPa to obtain mixed liquid, wherein the flow rate of the first composition is 40L/min and the flow rate of the second composition is 40L/min in the mixing process;

(4) Under the condition of 0.3MPa, injecting the mixed feed liquid into a die cavity of a top dome 1 die, waiting for 20s, and stopping injection; adjusting the deflection angle of the top dome 1 die to 45 degrees with the vibration frequency of 10Hz, and waiting for 250s; the temperature of the male die is reduced to 60 ℃, the temperature of the female die is reduced to 70 ℃, the deflection angle of the die of the top guide cover 1 is adjusted to 45 degrees at the vibration frequency of 10Hz, and 100s is waited for, so that the top guide cover 1 is obtained.

(5) And (3) repeating the step (4) to sequentially obtain the left upper guide sleeve 2, the right upper guide sleeve 3, the left lower guide sleeve 4 and the right lower guide sleeve 4, and assembling to obtain the first guide sleeve assembly.

As a comparative example, the tilt angle and vibration frequency in the above steps were canceled to obtain a second pod assembly; the appearances of the first pod assembly and the second pod assembly are shown in fig. 3 and 4, respectively, and the comparison of the first pod assembly and the second pod assembly shows that: the appearance of the product can be changed by adopting a certain vibration frequency and an inclination angle, so that the surface of the product is smoother, and no bubbles appear in the product temporarily.

As another comparative example, the vibration frequency in the above step is cancelled, the inclination angle is reserved, a third air guide sleeve component is obtained, the inclination angle of the mould is increased by the third air guide sleeve component on the basis of the second air guide sleeve component, the number of air holes of the prepared product is obviously reduced after the mould is subjected to certain inclination through comparison, meanwhile, the surface quality of the product is correspondingly improved to a certain extent, and the tensile strength of the material is also improved; the viscosity of the feed liquid is very low, the die is inclined to a certain angle, so that the die has certain benefit for overflow of the air holes, accumulation of the air holes in the material can be reduced, and elimination of the air holes is improved.

Comparing the first air guide sleeve component with the third air guide sleeve component finds that: the first air guide sleeve component improves the pressure of the mixing head and increases the vibration of the mould on the basis of the third air guide sleeve component, and as a result, the surface appearance of the product is smooth, and no bubbles appear in the product temporarily. The pressure of the mixing head is increased, so that the full mixing of the feed liquid is facilitated, the bubble defect is reduced, meanwhile, the vibration effect of the die is increased, the removal of gas in the feed liquid is facilitated, and the product performance is improved.

In an embodiment, the inclination angle in the above step is increased to obtain a fourth pod assembly, and the comparison between the first pod assembly and the fourth pod assembly finds that: the fourth air guide sleeve component improves the inclination angle on the basis of the first air guide sleeve component, the feed liquid is inclined by a certain angle in the process of filling the die, certain benefits are provided for gas overflow, but the gas cannot be inclined too much, so that the gas in the feed liquid is influenced to be discharged, and the gas is discharged by controlling a certain inclination angle through analysis.

In an embodiment, increasing the vibration frequency while increasing the inclination angle in the above step obtains a fifth pod assembly: comparing the fourth pod assembly with the fifth pod assembly reveals that: because the reinforcing rib parts in the product can play a role in blocking the flow of feed liquid, the vibration frequency is more beneficial to sink marks of some reinforcing rib parts in the die, and the periphery is favorably filled with the material flow completely, so that the sink marks at the joint are eliminated.
