Abstract

The invention relates to the technical field of injection molds, in particular to an injection mold for keeping the temperature of a melt material uniform. The injection mold is provided with a surface plate, an upper mold fixing plate, an upper mold body, a lower mold body, a lower mold fixing plate, a cushion block, a surface pin plate, a bottom pin plate and a bottom plate, all of which are arranged from top to bottom in sequence. Locating rings are arranged in the center of the surface plate and the center of the bottom plate. A hot runner used for penetrating the interior of a cavity formed by the upper mold body and the lower mold body is arranged in the locating ring in the center of the surface plate, a hot runner insert is arranged at the bottom of the hot runner and filled with a first cooling water pipeline adjacent to an injection opening, and a second cooling water pipeline adjacent to the cavity is arranged in the upper mold body. According to the injection mold, the injection opening with the highest temperature is independently cooled through the first cooling water pipeline, the second cooling water pipeline is used for carrying out water cooling on the melt material in the cavity, so that the temperature of the melt material in the cavity is uniform, curing molding of the melt material is accelerated, and the rate of finished plastic products is greatly improved.

Description

Keep the uniform injection mold of melting material temperature
Technical field
The present invention relates to the technical field of injection mold, especially the uniform injection mold of a kind of maintenance melting material temperature.
Background technology
Injection mold is the instrument producing plasthetics, and the material melted that is heated is injected die cavity by high pressure by it, after cooling curing, obtains formed products.Because of the impact of mould inside environment, height is not etc. yet for the temperature being shot in the fused materials in die cavity, local is easily gathered to the fused materials position of too much heat, the material at this position is easily caused to be degraded, have a strong impact on the shaping of whole plastic products, cause the decrease in yield of plastic products.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of and keep the uniform injection mold of melting material temperature, overcome in prior art the problem of the non-uniform temperature that there is fused materials in injection mold.
The technical solution adopted for the present invention to solve the technical problems is: the uniform injection mold of a kind of maintenance melting material temperature, has the panel, upper mould fixed plate, upper die and lower die, counterdie fixed head, cushion block, face needle plate, end needle plate and the base plate that set gradually from top to bottom; The center position of described panel and the center position of base plate are provided with locating ring, the described locating ring being positioned at face plate center position is provided with the hot flow path for the die cavity formed through upper die and lower die, the bottom of described hot flow path is provided with hot flow path mold insert, fill out the first cooling water pipeline being provided with contiguous injection port in described hot flow path mold insert, in described patrix, row is provided with second cooling water pipeline at contiguous cavity positions place.
Further restriction, is provided with multiple support column between the counterdie fixed head described in technique scheme and base plate.
Further restriction, the end needle plate described in technique scheme is provided with the mouth of a river thimble for withstanding the first cooling water pipeline.
Further restriction, the cushion block described in technique scheme and be provided with between end needle plate to reset and confirm switch.
The invention has the beneficial effects as follows: the uniform injection mold of maintenance melting material temperature of the present invention, fill out in hot flow path mold insert and establish the first cooling water pipeline of contiguous injection port and in patrix, arrange the second cooling water pipeline establishing contiguous cavity positions place, the injection port utilizing the first cooling water pipeline the highest to temperature cools separately, the second cooling water pipeline is utilized to carry out water cooling to the fused materials being arranged in die cavity, make the homogeneous temperature of the fused materials be injected in die cavity and accelerate fused materials curing molding, substantially increasing the yield rate of plastic products.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The present invention as shown in Figure 1 keeps the uniform injection mold of melting material temperature, has the panel 1, upper mould fixed plate 2, patrix 3, counterdie 4, counterdie fixed head 5, cushion block 6, face needle plate 7, end needle plate 8 and the base plate 9 that set gradually from top to bottom; The center position of panel 1 and the center position of base plate 9 are provided with locating ring 10, the locating ring 10 being positioned at panel 1 center position is provided with the hot flow path 11 for the die cavity formed through patrix 3 and counterdie 4, the bottom of hot flow path 11 is provided with hot flow path mold insert 12, fill out the first cooling water pipeline 13 being provided with contiguous injection port in hot flow path mold insert 12, in patrix 3, row is provided with second cooling water pipeline 14 at contiguous cavity positions place.
Wherein, multiple support column 15 is provided with between counterdie fixed head 5 and base plate 9.End needle plate 8 is provided with the mouth of a river thimble 16 for withstanding the first cooling water pipeline 13.Being provided with between cushion block 6 and end needle plate 8 resets confirms switch 17.
This injection mold, fill out in hot flow path mold insert 12 and establish the first cooling water pipeline 13 of contiguous injection port and in patrix 3, arrange the second cooling water pipeline 14 establishing contiguous cavity positions place, the first cooling water pipeline 13 pairs of injection ports that temperature is the highest are utilized to cool separately, the second cooling water pipeline 14 is utilized to carry out water cooling to the fused materials being arranged in die cavity, make the homogeneous temperature of the fused materials be injected in die cavity and accelerate fused materials curing molding, substantially increasing the yield rate of plastic products.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
