Abstract
The invention provides a plastic injection mold which comprises an upper mold, a lower mold and a lifting device, wherein a plastic injection hole is formed in the upper mold, and a plastic injection runner is arranged in the upper mold; a mold cavity is formed in the lower mold, and a heating device is arranged in the lower mold and comprises heating pipelines which are uniformly paved in the lower mold and used for heating the mold cavity; the lifting device comprises a mobile supporting seat and a hydraulic cylinder, the hydraulic cylinder is arranged at the bottom of the lower mold close to one end of the plastic injection hole, and the mobile supporting seat is arranged at the bottom of the lower mold far away from one end of the plastic injection hole. Before plastic injection, one end of the mold is lifted up through the hydraulic cylinder, and then a plastic solution is injected into the mold. As one end of the mold is lifted up, air in the mold cavity is discharged when the plastic solution is injected, the whole mold cavity can be uniformly full of the plastic solution. In the plastic injection process, the heating device in the lower mold can heat the mold cavity so as to prevent the plastic solution from condensing. The plastic injection mold has the advantages of being simple in structure, convenient to use and good in plastic injection effect.
Description
Technical field
The invention belongs to mould applications, especially relate to a kind of injection mold.
Background technology
Traditional injection moulding mould generally comprises mold and bed die, mold is arranged injection molding channel and cast termination, bed die arranges mold cavity, after mold and bed die grafting, plastic solution injects from injection molding channel and pours into a mould termination, the die cavity of bed die is injected again by cast termination, mold is separated with bed die after cooling, can obtain the product after injection moulding.But carrying out in injection moulding process, because injection molding material just can condense in the extremely short time, therefore air can be contained in mold cavity inside, easily forms pore, causes the overall performance of injection molding material to reduce, thus affects the intensity of injection molding body.
Summary of the invention
The problem to be solved in the present invention is to provide the injection mold that a kind of structure is simple, injection moulding is effective.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of injection mold, comprise mold, bed die, be arranged on the lowering or hoisting gear bottom bed die and Working gantry, described Working gantry is provided with described bed die, described mold is provided with injecting hole, injection molding channel is provided with in described mold, described bed die arranges mold cavity, be provided with to the heater of mold cavity heating in described bed die, described heater comprises uniform spreading and is located in bed die to the heating pipe line of mold cavity heating, described lowering or hoisting gear comprises movable supporting seat and hydraulic cylinder, described hydraulic cylinder is arranged on bottom the bed die of injecting hole one end, described movable supporting seat is arranged on bottom the bed die away from injecting hole one end.
Further, between the heating pipe line in described heater, be also filled with Heat Conduction Material, heater is fully heated to the plastic solution in mold cavity.
Further, in described bed die, be also provided with air flue, in the mold cavity on described bed die, be provided with the valve be connected with source of the gas, make the easy demoulding of the product after injection moulding.
The advantage that the present invention has and good effect are: first lifted by hydraulic cylinder one end by mould before injection moulding, then mould injected plastic solution is given, because one end of mould is lifted, air when making injection moulding solution in mold cavity is discharged, plastic solution can evenly be covered with whole mold cavity, in injection moulding process, the heater in bed die can heat mold cavity, prevents plastic solution from condensing; There is the advantages such as structure is simple, easy to use, injection moulding is effective.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Figure 1, a kind of injection mold, comprise mold 1, bed die 2, be arranged on the lowering or hoisting gear bottom bed die 2 and Working gantry 10, described Working gantry 10 is provided with described bed die 2, described mold 1 is provided with injecting hole 3, injection molding channel is provided with in described mold 1, described bed die 2 arranges mold cavity 6, the heater heated to mold cavity 6 is provided with in described bed die 2, described heater comprises uniform spreading and is located in bed die 2 to the heating pipe line 4 that mold cavity 6 heats, Heat Conduction Material 5 is also filled with between described heating pipe line 4, heater is fully heated to the plastic solution in mold cavity 6, also air flue is provided with in described bed die 2, the valve 7 be connected with source of the gas is provided with in mold cavity 6 on described bed die 2, make the easy demoulding of the product after injection moulding, described lowering or hoisting gear comprises movable supporting seat 8 and hydraulic cylinder 9, described hydraulic cylinder 9 is arranged on bottom the bed die 2 of injecting hole 3 one end, described movable supporting seat 8 is arranged on bottom the bed die 2 away from injecting hole 3 one end.
The course of work of this example: first by mold 1 and bed die 2 grafting, first lifted by hydraulic cylinder 9 one end by mould before injection moulding, then mould injected plastic solution is given by injecting hole 3, because one end of mould is lifted, air when making injection moulding solution in mold cavity 6 is discharged, plastic solution evenly can be covered with whole mold cavity 6, in injection moulding process, heater in bed die 2 can heat mold cavity 6, prevent plastic solution from condensing, by hydraulic cylinder 9, mould is put down after plastic solution fills, heating-stopping apparatus heats mold cavity 6, then after the plastic solution cooling in mould, mold 1 is separated with bed die 2, product after the 7 pairs of injection mouldings of valve in mold cavity 6 carries out the demoulding.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
