Abstract

A horn mold insert is applied to a product which needs glue to enter in a lurking mode in a mold. The mold comprises a male mold core and a female mold core. The horn mold insert comprises a mold insert, a top block, a runner and a pouring gate. The mold insert is arranged inside the male mold core. The top surface of the mold insert is connected with the top surface of the male mold core. The top block is arranged inside the male mold core and closely adjacent to one side of the mold insert. An extending portion is arranged at the top end of the top block in the horizontal direction. The extending portion is arranged on the top surface of the top block and the top surface of the male mold core. One part of the runner is arranged on the joint portion of the top surface of the mold insert and the extending portion, and the other part of the runner is arranged on the joint portion of the top surface of the male mold core and the extending portion. The size of the cross section of the runner reduces gradually. The pouring gate is arranged on the joint of the tip of the runner and the product. The horn mold insert enables ejection of a double injection mold to be simplified, achieves forming of some products which have a longer horn runner and some products which include glass fiber materials, shortens production cycle of the mold, improves efficiency and lowers cost.

Description

Ox horn enters son

[technical field]

The utility model relates to the minor structure that enters in a kind of mould, is specifically related to a kind of ox horn and enters minor structure.

[background technology]

In the plastic mould Shooting Technique, if, during the full outward appearance of product requirement of injection moulding, generally can adopt submarine type glue feeding, submarine type glue feeding generally adopts ox horn to enter son, it is a back-off form that common ox horn enters son, by have two monomers discharge respectively processing after be spliced.Along with electronic product constantly upgrades, especially the appearance of some double-color molds, double color mould flexible glue part wherein must be hidden into glue with ox horn, add that the deflection of flexible glue is larger if the ox horn runner of flexible glue part is long, thereby it is wayward and can not well eject to the runner of flexible glue part to make ox horn enter son, finally can cause the production cycle of mould to lengthen, decrease in efficiency, cost increases; The plastic cement products that adds glass fibre for some in addition can not be used this conventional ox horn to enter son, because too crisp, the ox horn runner is will a top disconnected to be stayed ox horn and enter in son.

In view of this, in fact be necessary to provide a kind of ox horn to enter son, be difficult for being ejected to solve because conventional ox horn enters the stub bar that sub back-off enters in son ox horn, cause the problems such as the lengthening of mould production cycle, decrease in efficiency and cost increase.

[summary of the invention]

In order to achieve the above object, the utility model provides a kind of ox horn to enter son, and it is applied in mould need the product of hiding into glue, and this mould comprises male die core and mother module core, and this ox horn enters attached bag and draws together:

Enter son, it is located in described male die core, describedly enters sub-end face and described male die core end face links together;

Jacking block, it is located in described male die core and is close to a described side that enters son, and this jacking block top has an extension in the horizontal direction, and described extension is located at and is describedly entered on sub-end face and described male die core end face;

Runner, its part is located at the described joint portion that enters sub-end face and described extension, and another part of this runner is located at the joint portion of described male die core end face and described extension, and the sectional dimension of this runner is dwindled gradually;

Cast gate, it is located at described runner tip and described product connection.

Preferably, described extension enters sub-end face and described male die core end face coordinates with described.

Preferably, the shape of described runner is as the smooth curve shape cone of ox horn formula.

Compared to prior art, it is open that the utility model ox horn enters sub runner, almost can reach zero back-off, this ox horn enters son mainly by described die and enter subgroup and become, then be pressed in and describedly enter that son is upper forms a runner with described jacking block, to reach the purpose into glue, this runner is an open runner, and a top can eject the stub bar in this runner gently.This ox horn enters son and makes double-color mold eject simplification, and has realized that some ox horn runners are grown and some add the moulding of glass fibre material product, has reduced the mould production cycle, improved efficiency and has reduced cost.

[accompanying drawing explanation]

Fig. 1 illustrates and enters sub exploded view for the utility model ox horn.

Fig. 2 illustrates and enters sub structural representation for the utility model ox horn.

Fig. 3 illustrates and enters sub side sectional view for the utility model ox horn.

[specific embodiment]

Below in conjunction with accompanying drawing, the utility model specific embodiment is described in detail.

Please refer to shown in Fig. 1 and Fig. 2, the utility model provides a kind of ox horn to enter son, and it is applied in mould need the product 10 of hiding into glue, and this mould comprises male die core 300, mother module core 400, thimble 500 and liftout plate, and this ox horn enters attached bag and draws together:

Enter son 100, it is located in described male die core 300, describedly enters sub 100 end faces and described male die core 300 end faces link together;

Jacking block 200, it is located in described male die core 300 and is close to a described side that enters son 100, these jacking block 200 tops have an extension in the horizontal direction, described extension is located at and is describedly entered on sub 100 end faces and described male die core 300 end faces, and described extension enters sub 100 end faces and described male die core 300 end faces coordinate with described simultaneously;

Runner 110, its part is located at the described joint portion that enters sub 100 end faces and described extension, another part of this runner 110 is located at the joint portion of described male die core 300 end faces and described extension, the sectional dimension of this runner 110 is dwindled gradually, and the shape of wherein said runner 110 is as the smooth curve shape cone of ox horn formula;

Cast gate 120, it is located at described runner 110 tips and described product 10 connections.

In the present embodiment, described runner 110 is located at described thimble 500 upper ends, described thimble 500 lower ends are located on described liftout plate, the bottom of described jacking block 200 is located on described liftout plate, during die sinking, by ejecting mechanism, described liftout plate is upwards ejected, described liftout plate drives described jacking block 200 and upwards ejects, described jacking block 200 is separated with the described end face that enters sub 100 end faces and described male die core 300, now the stub bar in runner 110 is outside exposed, described thimble 500 upwards pushes up the stub bar in described runner 110 simultaneously, thereby by the stub bar in runner 110 and describedly enter son 100 and described male die core 300 breaks away from, this mould completes this ox horn and enters ejecting of sub-stub bar.

Compared to prior art, it is open that the utility model ox horn enters sub runner, almost can reach zero back-off, this ox horn enters son mainly by described male and

female die

300 and 400 and enter son and 100 form, then described jacking block 200 is pressed in to the described runner 110 that enters on son 100 and described male die core 300 to form, to reach the purpose into glue, this runner 110 is open runners, and a top can eject the stub bar in this runner 110 gently.This ox horn enters son and makes double-color mold eject simplification, and has realized that some ox horn runners are grown and some add the moulding of glass fibre material product, has reduced the mould production cycle, improved efficiency and has reduced cost.

Be pointed out that; the utility model is not limited to above-mentioned embodiment; any simple modification, equivalent variations and modification that any those skilled in the art do above-described embodiment based on technical solutions of the utility model, all fall in protection domain of the present utility model.
