Abstract

The utility model discloses a blowing mold which comprises an upper mold and a lower mold, wherein the upper mold comprises an upper template and an upper mold core; an upper forming cavity is formed in the lower surface of the upper mold core; a blowing channel and a vertically arranged blowing ejector sleeve are arranged on the upper mold core; the blowing ejector sleeve is communicated with the upper forming cavity and the blowing channel; a meshed separating blocking piece is arranged at the communicated end of the blowing ejector sleeve and the upper forming cavity; external threads are formed on the circumference of the meshed separating blocking piece, and the meshed separating blocking piece are in screwed connection with the inner wall of a lower end port of the blowing ejector sleeve; and the blowing channel is communicated with a blowing mechanism. The blowing mold adopts a design of a blowing mode, has the advantages of smooth blowing, lower probability of blockage and the like, and effectively solves the problem that a product is stuck to the cavity; and the blowing mold belongs to the technical field of mold equipment.

Description

Blowing mould

Technical field

The utility model belongs to die apparatus technical field, especially relates to a kind of blowing mould.

Background technology

When the thermal insulation board of engine is main, preventing heat effects that engine the produces paint to bonnet, is exactly the engine vibration that alleviated to a certain extent in addition.

As the thermal insulation board that Fig. 1 is engine, the package power of cavity surface and core plan is similar, and mould, in the time producing, always occurs the phenomenon of sticky die cavity, deals with very difficultly, has affected die trial efficiency and manufacturing schedule.

Utility model content

Technical problem to be solved in the utility model is: a kind of blowing mould is provided, has the advantages such as smooth and easy, difficult obstruction of blowing, can effectively solve the phenomenon of the glutinous die cavity of product.

Technical solution adopted in the utility model is: a kind of blowing mould, comprise upper die and lower die, patrix comprises cope match-plate pattern and upper mold core, upper mold core lower surface is upper forming cavity, described upper mold core is provided with insufflation channel and the vertical air blowing ejector sleeve arranging, air blowing ejector sleeve is communicated with upper forming cavity, and insufflation channel is communicated with air blowing ejector sleeve; Described air blowing ejector sleeve is communicated with end and is provided with netted obstruct catch with upper forming cavity, described netted obstruct catch circumference is provided with external screw thread and is spirally connected with air blowing ejector sleeve lower port inwall, and insufflation channel is communicated with inflatable body.

Described inflatable body is high-pressure pump, and the escape pipe of high-pressure pump is connected with insufflation channel external port, and the escape pipe of high-pressure pump is connected with pressure controller.

The beneficial effects of the utility model are: a kind of blowing mould of the utility model, and in this mold design, take the mode that adds air blowing to design, there is the advantages such as smooth and easy, difficult obstruction of blowing, effectively solve the phenomenon of the glutinous die cavity of product.

Detailed description of the invention

Shown in Fig. 1-Fig. 4, a kind of blowing mould, comprise upper die and lower die, patrix comprises cope match-plate pattern and upper mold core 1, upper mold core 1 lower surface is upper forming cavity 1.1, described upper mold core 1 is provided with insufflation channel 1.2 and the vertical air blowing ejector sleeve 2 arranging, and air blowing ejector sleeve 2 is communicated with upper forming cavity 1.1, and insufflation channel 1.2 is communicated with air blowing ejector sleeve 2; Described air blowing ejector sleeve 2 is communicated with end and is provided with netted obstruct catch 3 with upper forming cavity 1.1, described netted obstruct catch 3 circumference are provided with external screw thread and are spirally connected with air blowing ejector sleeve 2 lower port inwalls.The effect of netted obstruct catch 3 is, the lower port of air blowing ejector sleeve 2 is blocked, can effectively avoid matched moulds after material enter air blowing ejector sleeve 2 lower port, affect formed product and air blowing.The utility model mould is thermoplastic mould, not injection mould, all material embryos are all that heating after-tack is compressing, because the through hole of netted obstruct catch 3 is smaller, material cannot enter the through hole of netted obstruct catch 3, therefore netted obstruct catch 3 can not blocked.Netted obstruct catch 3 is spirally connected with air blowing ejector sleeve 2 lower port inwalls, and dismounting is convenient, is convenient for changing netted obstruct catch 3.

Insufflation channel 1.2 is communicated with inflatable body.Described inflatable body is high-pressure pump 4, and the escape pipe 5 of high-pressure pump 4 is connected with insufflation channel 1.2 external port, and the escape pipe 5 of high-pressure pump 4 is connected with pressure controller 6.Pressure controller 6 is controlled the dynamics that enters insufflation channel 1.2.The described similar pressure valve of controller 6.

Operation principle of the present utility model is: after formed product, through air pump, gas is blown into by insufflation channel 1.2, between product and upper forming cavity 1.1, pours into gas, be convenient to the demoulding.

A kind of blowing mould of the utility model, in this mold design, takes the mode that adds air blowing to design, and has the advantages such as smooth and easy, difficult obstruction of blowing, and effectively solves the phenomenon of the glutinous die cavity of product.
