This utility model solves the technical scheme for being adopted of its technical problem：

A kind of mould for producing gripper shoe, including upper die plate, lower template and feeding-passage, the upper die plate bottom surface sets molding Portion, the lower template top surface sets forming part, and forming part and lower forming part can constitute the die cavity of contoured support plate with merging on this, should Feeding-passage connects die cavity；Also include drive mechanism and cutting knife, the drive mechanism is located at lower template, and the cutting knife is slidably installed in down up and down Template, the drive mechanism be connected cutting knife with drive the relative lower template of cutting knife between initial position and blank position on glide Dynamic, the blade of the cutting knife is directed at the junction of feeding-passage and die cavity, and the cutting knife slides into blank position process from initial position In the cutting knife blade cut-out molding gripper shoe and material mouth connection.

Among one embodiment：Assembly space is provided with the lower template and the assembly space inwall and lower template outer wall is connected Groove；The drive mechanism includes several side by side or array is fixedly connected on the cylinder in assembly space, the vapour-liquid pipe of the cylinder By groove assembly space is stretched into inside and connects cylinder outward certainly, the dorsad blade of all affixed cutting knife of several the piston rod Back of the body side.

Among one embodiment：The lower template includes the first template and the second template under the first template, and this first The bottom surface of template is provided with upper groove, and the top surface of second template is arranged with low groove, first template and the second template it is affixed and Upper groove and low groove align and constitute assembly space.

Among one embodiment：The cutting knife has matrix and the edge of a knife, and the edge of a knife is fixed in the top of matrix, and the knife edge thickness is little In matrix thickness and edge of a knife the first side wall and matrix the first side wall are flushed, the matrix top surface has one to stretch out edge of a knife second sidewall End wall, the edge of a knife second sidewall and end wall rounding off, the blade is located at edge of a knife top.

Among one embodiment：The junction of the edge of a knife the first side wall alignment feeding-passage and die cavity, the lower template is installed with Tool rest is led, the second sidewall of the edge of a knife is abutted against and leads tool rest.

Compared with background technology, it has the advantage that the technical program：

Mould also includes drive mechanism and cutting knife, the blade alignment feeding-passage of cutting knife and the junction of die cavity, and cutting knife is certainly Initial position slides into the gripper shoe of the blade cut-out molding of the cutting knife during blank position and the connection of material mouth, then this technology The mould of scheme can cut off the connection of gripper shoe and material mouth after shaping and before shaped article is fully hardened using cutting knife, therefore Can overcome the shortcomings of existing for background technology, and produce following technique effect：Cutting, easily cutting before one, shaped article hardening, Required cutting force is little；Second, cut-off part is flushed, and appearance looks elegant, high yield rate, without the need for follow-up lapping process.

Drive mechanism includes several cylinders, all affixed cutting knife of piston rod of those cylinders, and drive mechanism is located at assembling In space, vapour-liquid Gutron crosses groove, and from stretching into inside outward, assembly space is interior to connect cylinder, on the one hand, cutting force is big once to be cut The connection of all of contoured support plate and material mouth on the mould, on the other hand, simple structure is rationally distributed, compact conformation.

First template and the second template is affixed and upper groove and low groove align and constitute assembly space, mould is easily assembled, Convenient maintenance, compact conformation.

Knife edge thickness is less than matrix thickness and edge of a knife the first side wall and matrix the first side wall are flushed, and matrix top surface has one to stretch Go out the end wall of edge of a knife second sidewall, edge of a knife second sidewall and end wall rounding off, blade is located at edge of a knife top, is easily oriented to cutting knife and slides Dynamic direction, it is ensured that cutting knife blade cuts off the connection of molding gripper shoe and material mouth.

The junction of edge of a knife the first side wall alignment feeding-passage and die cavity, lower template is installed with leads tool rest, and the second of the edge of a knife Side wall is abutted against leads tool rest, and guide effect is good.

Description of the drawings

With reference to the accompanying drawings and examples the utility model is described in further detail.
