Abstract
The utility model provides an avoid thermal-insulated strip forming die of jam belongs to thermal-insulated strip production technical field. Comprises a flat tubular body; from the discharge port to the feed inlet, a pressurizing section with gradually increasing aperture is arranged at one end of the body close to the feed end, a releasing section with gradually decreasing aperture is arranged at one end of the body close to the discharge end, and a straight section is arranged between the releasing section and the pressurizing section. The utility model has the advantages of can avoid extruding advantages such as in-process product jam.
Description
Technical Field
The utility model belongs to the technical field of the production of heat insulating strip, a avoid heat insulating strip forming die of jam is related to.
Background
The extrusion die of the polyamide heat insulation strip is composed of a plurality of forming dies which are arranged on a die body in order, the forming dies are of a tubular structure matched with a product, the position of a discharge port of the forming die is consistent with the cross section of the product so as to ensure that the product with a specified shape is formed after gradual cooling, substances such as residual glass fiber and the like in the polyamide heat insulation strip are used for improving the strength of the product, the polyamide heat insulation strip is heated by mixing to form a viscous extrusion material, partial materials are possibly not completely dispersed in the material mixing process, impurities influencing the surface flatness of the product are formed in the extrusion process, the discharge port of the existing extrusion die is gradually contracted to the shape of the product, the product is easily blocked at the position when the impurities are discharged, and therefore the adverse conditions such as deformation, incomplete and the like are formed around the position of the impurities in the product extrusion.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that exists to current technique, provide a avoid thermal-insulated strip forming die of jam, the utility model aims to solve the technical problem how avoid extruding the jam problem that causes because of raw materials impurity.
The purpose of the utility model can be realized by the following technical proposal: a thermal insulating strip forming die capable of avoiding blockage is characterized by comprising a flat tubular body; from the discharge gate to the feed inlet, the body is gone up and is close to feeding one end and has a pressure boost section that the aperture is crescent, the body is close to ejection of compact one end and has a release section that the aperture is gradually reduced, a straight section has between release section and the pressure boost section.
Further, the body is fixedly provided with a rubber sealing plate which is parallel and level with the end face of the discharge hole.
Furthermore, the joint of the rubber sealing plate and the outer wall surface of the body at the upper part of the body is provided with a temperature control part, and the wall thickness of the body at the temperature control part is greater than the wall thickness of other parts at the joint of the rubber sealing plate and the body.
Set up a aperture and enlarge gradually, and be greater than the release section of straight section near discharge gate one side in the straight section of body, the shaping raw materials causes the extrusion resistance increase when there is impurity, but because the release section aperture behind the straight section end is crescent, makes the extrusion resistance can be alleviated at this position to ejection of compact jam problem has effectively been avoided.
Because pressure boost section and partial straight section are located the cooling chamber, rivers are from top to bottom, in order to alleviate the inhomogeneous that the water-cooling leads to, set up temperature control portion, make the lower body upper end of temperature, be close to the position thickness that is close to straight section promptly and be greater than other positions to reduce the sensitivity of being heated of the lower department of temperature, improve the homogeneity of being heated and the homogeneity of extruding of product.
Drawings
Fig. 1 is a sectional view of a molding die.
Fig. 2 is a left side view of fig. 1.
In the figure, 1, a body; 11. a pressurizing section; 12. a release section; 13. a straight section; 2. sealing a rubber plate; 3. a temperature control unit.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, comprises a flat tubular body 1; from the discharge port to the feed inlet, a pressurizing section 11 with gradually increasing aperture is arranged on the body 1 near the feeding end, a releasing section 12 with gradually decreasing aperture is arranged on the body 1 near the discharging end, and a straight section 13 is arranged between the releasing section 12 and the pressurizing section 11.
The body 1 is fixedly provided with a glue sealing plate 2 which is parallel and level with the end face of the discharge hole. The joint of the glue sealing plate 2 and the outer wall surface of the body 1 at the upper part of the body 1 is provided with a temperature control part 3, and the wall thickness of the body 1 at the temperature control part 3 is larger than the wall thickness of other parts at the joint of the glue sealing plate 2 and the body 1.
Set up a aperture and enlarge gradually, and be greater than the release section 12 of straight section 13 on one side of the straight section 13 of body 1 is close to discharge gate, and the shaping raw materials causes the resistance increase of extruding when there is impurity, but because the release section 12 aperture behind the straight section 13 end is crescent, the resistance that makes to extrude can be alleviated at this position to ejection of compact jam problem has effectively been avoided.
Because pressure boost section 11 and part straight section 13 are located the cooling chamber, rivers are from top to bottom, in order to alleviate the inhomogeneous that the water-cooling leads to, set up temperature control portion 3, make the lower body 1 upper end of temperature, be close to the position thickness that is close to straight section 13 promptly and be greater than other positions to reduce the sensitivity of being heated of the lower department of temperature, improve the homogeneity of being heated and the extrusion homogeneity of product.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
