The utility model has the advantages of the design has slag chute and runner, and slag chute and runner cooperate and can heat conduction heat dissipation fast for cooling rate to promote work efficiency.

The utility model has the advantages of the product is pleasing to the eye, work efficiency is high, the shaping is effectual.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is the structure diagram of the joint between the front mold and the rear mold of the present invention.

In the figure: the device comprises a base plate 1, an ejector pin base plate 2, an ejector pin panel 3, square iron 4, a cushion block 5, an ejector pin 6, a rear die 7, a front die 8, a guide block 9, a screw 901, a flow channel 10, a cavity 11, a feed inlet 12 and a slag groove 13.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the present application, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without inventive achievements all belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in the figure, the utility model provides a technical scheme: the utility model provides a production mould of VCM motor base anti-ejection pin mark, includes: bottom plate 1, front mould 8 and back mould 7, 1 top of bottom plate is equipped with

thimble bottom plate

2, 2 tops of thimble bottom plate are equipped with

thimble panel

3, 3 top both sides of thimble panel install back mould 7 through square iron 4, 7 tops of back mould are equipped with the front mould 8 of looks adaptation, be equipped with die cavity 11 between front mould 8 and the back mould 7, evenly laid a plurality of material sediment grooves 13 at both ends around the die cavity 11, one side that die cavity 11 was kept away from to material sediment groove 13 all is equipped with runner 10, material sediment groove 13 and runner 10 cooperate and can heat conduction heat dissipation fast, accelerate cooling rate, and the work efficiency is improved. A thimble 6 is arranged below the slag groove 13, the thimble 6 penetrates through the rear die 7 to be connected with the thimble panel 3, a guide block 9 is arranged at the lower end of the thimble 6 positioned on the rear die 7, and the guide block 9 can limit the thimble 6. Two sides of the guide block 9 are connected with the lower end of the rear die 7 through screws 901. The joint of the tail end of the thimble 6 and the thimble panel 3 is provided with a cushion block 5.

Example two:

the difference between the present embodiment and the first embodiment is: the slag trough 13 is arranged in two rows, and each row is 4, so the thimble 6 correspondingly arranged below the slag trough 13 is also arranged in two rows, and each row is 6.
