Abstract
The utility model discloses an injection molding mold which comprises a bracket, a movable mold, a fixed mold and two supporting columns, wherein a first fixing plate, a stripping plate and a second fixing plate are sequentially arranged on the movable mold; the two supporting columns respectively penetrate through the first fixing plate, the stripping plate and the second fixing plate; flanges are arranged on the supporting columns; springs for jacking the stripping plate up are arranged on the flanges and penetrate through the first fixing plate; bulges for limiting a moving range of the second fixing plate are arranged on the outer walls of the tops of the supporting columns; the second fixing plate is connected with a moving mechanism on an injection molding machine; and the moving range of the second fixing plate is wider than that of the stripping plate. The injection molding mold is simple in structure and convenient to use; condensed materials in a mold flow channel can be completely separated; the production efficiency is improved; and the cost is reduced.
Description
Technical field
The utility model belongs to technical field of mold, is specifically related to a kind of injection mold.
Background technology
Injection mold is comprised of dynamic model and cover half two parts, and dynamic model is installed on the moving die plate of injection (mo(u)lding) machine, and cover half is installed on the fixed form of injection (mo(u)lding) machine.Dynamic model and cover half closed formation running gate system and die cavity when injection moulding, dynamic model separates in order to take out plastic products with cover half during die sinking.
In the die sinking process, by ejecting mechanism plastic products and the solidifying material in runner thereof are released or pulled out.It is not thorough that prior art exists the solidifying material in the runner to break away from, and affects the defective of duplication of production.
The utility model content
The utility model purpose: the purpose of this utility model is for the deficiencies in the prior art, and a kind of injection mold is provided, and it is simple in structure, and is easy to use, can break away from the solidifying material in the mold runner up hill and dale, has improved production efficiency.
Technical scheme: a kind of injection mold described in the utility model, comprise support, dynamic model and cover half, be disposed with the first fixed head on the described dynamic model, stripper plate and the second fixed head, also comprise two support columns, pass respectively the first fixed head, stripper plate and the second fixed head, be provided with flange on the described support column, be provided with the spring for the jack-up stripper plate on the flange, described spring passes the first fixed head, the top outer wall of described support column is provided with the projection of restriction the second fixed head moving range, and described the second fixed head is connected with travel mechanism on the injection machine, and the moving range of described the second fixed head is greater than the moving range of stripper plate.
For effective conserve space, be provided be used to the circular hole that passes support column on described the second fixed head, the inboard bottom of described circular hole is provided with the annular lip that matches with projection.
Further, described dynamic model is connected the location with cover half by locating hole with locating dowel.
Further, the dynamic model side of described dynamic model is provided with glue-feeder.
During concrete operations, at first work as the second fixed head and move up under the travel mechanism of injection machine drives, thereby stripper plate is because the spring force effect moves up, drive is fed into sub the movement and takes off material, finishes and takes off material for the first time; When spring has not had elastic force, not when elongation, continue mobile the second fixed head, draw this moment the material pin to break away from runner, carry out taking off the second time material.
The utility model compared with prior art, its beneficial effect is: injection mold structure described in the utility model is simple, and is easy to use, can break away from the solidifying material in the mold runner up hill and dale, and production efficiency is provided, and reduced cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The below is elaborated to technical solutions of the utility model, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of injection mold, comprise support 1, dynamic model and cover half, described dynamic model is connected the location with cover half by locating hole with locating dowel, the dynamic model side of described dynamic model is provided with glue-feeder, be disposed with the first fixed head 2 on the described dynamic model, stripper plate 3 and the second fixed head 4, and this mould also comprises two support columns 5, pass respectively the first fixed head 2, stripper plate 3 and the second fixed head 4, be provided with flange 6 on the described support column 5, be provided with the spring 7 for jack-up stripper plate 3 on the flange 6, described spring 7 passes the first fixed head 2, the top outer wall of described support column 5 is provided with the projection 8 of restriction the second fixed head 4 movings range, is provided be used to the circular hole 9 that passes support column on described the second fixed head 4, and the inboard bottom of described circular hole 9 is provided with and projection 8 annular lip that match 10, described the second fixed head 4 is connected with travel mechanism on the injection machine, and the moving range of described the second fixed head 4 is greater than the moving range of stripper plate.
As mentioned above, although the specific preferred embodiment of reference has represented and has explained the utility model that it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make in the form and details various variations to it.
Claims (4)
