Description

Technical Field

[0001] The utility model relates to the technical field of mold equipment, in particular to a steam heating structure for a middle mold sleeve. Background Art

[0002] Tire molds are molds used for vulcanization molding of various tires. Tire molds mainly include flexible molds, which include upper side plates, the inner surface edge of the upper side plates is closely attached to the mold pattern blocks, the outer side of the mold pattern blocks is provided with a middle mold sleeve assembly, the inner side of the middle mold sleeve assembly is closely attached to the lower side plates, the surface of the lower side plates is closely attached to the mold pattern blocks, and the center mechanism of the vulcanizer is provided at the center axis of the upper side plates and the lower side plates.

[0003] At present, the main heating methods for active molds in tire factories include steamer type or hot plate type, both of which use high-temperature steam heat conduction. Among them: the hot plate type uses high-temperature steam to heat the upper and lower hot plates of the vulcanizer, and then conducts it to the upper and lower side plates of the mold through the upper cover and base of the mold sleeve. The steam enters the steam chamber of the middle mold sleeve, and the heat conduction slider conducts it to the pattern block to achieve overall heating of the mold.

[0004] However, when using this method for heating, a large number of water droplets will condense on the surface of the steam chamber of the middle mold sleeve. After the heating is completed, the water droplets will gather in the steam chamber of the middle mold sleeve, which is inconvenient to discharge. At the same time, the gathered condensed water will absorb the heat of the steam when the mold is heated next time, thereby affecting the heating effect of the mold. In addition, after the heating is completed, the condensed water will also transfer the heat of the mold to the outside in the opposite direction, thereby affecting the heating quality of the mold. Utility Model Content

[0005] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a steam heating structure for a middle mold sleeve, which can reduce condensed water in the steam chamber of the middle mold sleeve, thereby improving the heating quality of the mold.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a middle mold sleeve steam heating structure is arranged in the middle mold sleeve, including a steam chamber, the steam chamber is arranged in the middle mold sleeve, a steam inlet connected to the steam chamber is opened on the side of the steam chamber away from the pattern block, a plurality of guide grooves extending to the lower side plate are opened on the side wall of the steam chamber, a confluence groove connecting all the ends of the guide grooves is opened on the bottom of the steam chamber close to the lower side plate, and a condensate outlet connected to the confluence groove is opened on the side of the middle mold sleeve away from the pattern block.

[0007] Furthermore, the inner side surface of the steam chamber away from the side of the pattern block is perpendicular to the lower side plate and connected to the confluence groove, and the inner side surface of the steam chamber close to the side of the pattern block includes a vertical surface and an inclined surface, the vertical surface is located above and perpendicular to the lower side plate, and the inclined surface extends from the lower end of the vertical surface toward the confluence groove until it is connected to the confluence groove.

[0008] Furthermore, the guide groove completely covers the inner surface of the steam chamber.

[0009] Furthermore, the cross section of the guide groove is arc-shaped, and the side lines of two adjacent guide grooves are collinear.

[0010] Furthermore, an air duct is provided on the top of the steam chamber, and air can be blown into the steam chamber through the air duct.

[0011] Beneficial effects of the utility model:

[0012] When the steam heating structure of the middle mold sleeve needs to be heated, heating steam is first introduced into the steam chamber through the steam inlet, so that the active mold can be heated. When the heating is completed, the water vapor attached to the side wall of the steam chamber condenses into water droplets, and the water droplets flow downward under the action of gravity. During the downward flow, the guide groove guides the water droplets and gathers the scattered small water droplets into large water droplets, further ensuring that the water droplets will flow downward, thereby reducing the chance of the water droplets adhering to the side wall of the steam chamber.

[0013] After flowing into the bottom of the steam chamber, the confluence groove gathers the water droplets flowing out of the guide groove, and then the condensed water is released through the condensed water outlet.

[0014] The use of the above-mentioned middle mold sleeve steam heating structure can reduce the condensation water in the steam chamber after heating is completed, and avoid the accumulated condensation water absorbing steam heat when the mold is heated next time, thereby affecting the heating effect of the mold. In addition, it can reduce the probability of condensation water transferring the heat of the mold to the outside in reverse after heating is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0021] See also Figure 1 to Figure 2 The utility model provides a middle mold sleeve steam heating structure, which is arranged in the middle mold sleeve 1 and includes a steam chamber 4. The steam chamber 4 is arranged in the middle mold sleeve 1, and a steam inlet 11 connected to the steam chamber 4 is provided on the side of the steam chamber 4 away from the pattern block 2, and a plurality of guide grooves 5 extending to the lower side plate 3 are provided on the side wall of the steam chamber 4, and a confluence groove 6 connecting the ends of all the guide grooves 5 is provided on the bottom of the steam chamber 4 close to the lower side plate 3, and a condensate outlet 7 connected to the confluence groove 6 is provided on the side of the middle mold sleeve 1 away from the pattern block 2.

[0022] When heating is required, heating steam is first introduced into the steam chamber 4 through the steam inlet 11, so that the flexible mold can be heated. After the heating is completed, the water vapor attached to the side wall of the steam chamber 4 condenses into water droplets, and the water droplets flow downward under the action of gravity. During the downward flow process, the guide groove 5 guides the water droplets and gathers the scattered small water droplets into large water droplets, further ensuring that the water droplets will flow downward, thereby reducing the chance of the water droplets adhering to the side wall of the steam chamber 4.

[0023] After the water droplets flow into the bottom of the steam chamber 4 , the confluence groove 6 gathers the water droplets flowing out of the guide groove 5 , and then the condensed water is discharged through the condensed water outlet 7 .

[0024] The above-mentioned middle mold sleeve steam heating structure can reduce the condensation water in the steam chamber 4 after heating is completed, and avoid the accumulated condensation water absorbing the steam heat when the mold is heated next time, thereby affecting the heating effect of the mold. In addition, it can reduce the probability of the condensation water transferring the heat of the mold to the outside in reverse after heating is completed.

[0025] As a preferred embodiment, the inner side surface of the steam chamber 4 away from the pattern block 2 is perpendicular to the lower side plate 3 and connected to the confluence groove 6. The inner side surface of the steam chamber 4 close to the pattern block 2 includes a vertical surface 8 and an inclined surface 9. The vertical surface 8 is located above and perpendicular to the lower side plate 3. The inclined surface 9 extends from the lower end of the vertical surface 8 toward the confluence groove 6 until it is connected to the confluence groove 6. In the specific implementation, the guide groove 5 should be covered with the inner surface of the steam chamber 4 as much as possible.

[0026] This method can ensure that the condensed water droplets flow along the guide groove 5 and reduce the difficulty of processing the steam chamber 4.

[0027] As a more preferred implementation, the cross section of the guide groove 5 is arc-shaped, and the side lines of two adjacent guide grooves 5 are collinear. The cross section of the guide groove 5 is arc-shaped, which facilitates the convergence of water drops and reduces the blank area between the two guide grooves 5, further improving the convergence effect.

[0028] As another preferred embodiment, an air duct 10 may be provided at the top of the steam chamber 4. When in use, the air duct 10 is connected to an external blower to blow air into the steam chamber 4, and the water droplets are blown downward from the top of the steam chamber 4 along the guide groove 5, thereby improving the convergence effect and accelerating the flow rate of the water droplets, thereby reducing the time for discharging condensed water.

[0029] The usage of the steam heating structure of the middle mold sleeve 1 is as follows:

[0030] When heating is required, first introduce heating steam into the steam chamber 4 through the steam inlet 11, so that the active mold can be heated. After the heating is completed, the air duct 10 is connected to the blower to blow air into the steam chamber 4, and the condensate outlet 7 is connected to the outside world. The water vapor attached to the side wall of the steam chamber 4 condenses into water droplets, which flow into the confluence groove 6 along the guide groove 5 and gather together. Finally, the condensed water flows out through the condensate outlet 7.

[0031] The above-mentioned middle mold sleeve steam heating structure can reduce the condensation water in the steam chamber 4 after heating is completed, and avoid the accumulated condensation water absorbing the steam heat when the mold is heated next time, thereby affecting the heating effect of the mold. In addition, it reduces the probability of the condensation water transferring the heat of the mold to the outside in the opposite direction after heating is completed.
