Description

Stripper plate extension block device for motor casing die

Technical Field

The utility model relates to the field of die devices, in particular to a stripper plate extension block device for a motor casing die.

Background

The mold is used for obtaining various molds and tools of required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production;

corresponding pouring runners are generally designed in the pouring process of the motor casing mould at present, but the longer runner design not only can cause the waste of resources, but also can reduce the production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a stripper plate extension block device for a motor casing die, which saves production resources.

The technical scheme of the utility model is as follows:

the stripper plate extension block device for the motor casing mould sequentially comprises an upper fixing plate, a stripper plate, a fixed template base plate and a fixed template from top to bottom; the center of the fixed die plate backing plate is provided with a groove, and a stripper plate extension block is arranged in the groove.

The stripper plate extension block comprises a main runner communicated with a sprue bush in the center of the upper fixing plate, and the bottom end of the main runner is respectively connected with a first sub-runner assembly and a second sub-runner assembly.

The first sub-runner assembly and the second sub-runner assembly respectively comprise a first-stage sub-runner close to and communicated with the main runner and a plurality of second-stage sub-runners connected with the first-stage sub-runners.

One end of the second-stage runner is communicated with the first-stage runner, and the other end of the second-stage runner is inserted into a fixed die insert at the bottom end of the fixed die plate.

And the four secondary sub-runners are connected with the primary sub-runner.

And the bottom ends of the secondary branch channels are provided with gates.

The utility model has the beneficial effects that: the concave groove is formed in the center of the fixed die base plate to form a concave space, so that the thickness of the center of the fixed die base plate is reduced; because the stripper plate extension block is arranged at the center of the fixed die base plate, the thickness of the center of the fixed die base plate is shortened, the length of the runner is indirectly shortened, the generation of waste materials of the runner is reduced, the utilization rate of plastics is increased, and the material cost is saved.

Detailed Description

Referring to fig. 1, the stripper plate extension block device for the motor casing mold sequentially comprises an upper fixing plate 1, a stripper plate 2, a fixed die plate backing plate 3 and a fixed die plate 4 from top to bottom; the center of the fixed die plate backing plate is provided with a groove 5, and a stripper plate extension block 6 is arranged in the groove. The concave groove is formed in the center of the fixed die base plate to form a concave space, so that the thickness of the center of the fixed die base plate is reduced; because the stripper plate extension block is arranged at the center of the fixed die base plate, the thickness of the center of the fixed die base plate is shortened, and the stroke of the stripper plate extension block is indirectly shortened.

The stripper plate extension block comprises a main runner 8 communicated with a sprue bush 7 in the center of the upper fixing plate, and the bottom end of the main runner is respectively connected with a first sub-runner assembly and a second sub-runner assembly. Indirectly shortening the length of the flow passage.

The first sub-runner assembly and the second sub-runner assembly respectively comprise a first-stage sub-runner 11 which is close to and communicated with the main runner and a plurality of second-stage sub-runners connected with the first-stage sub-runners. Flow of pouring liquid is accelerated by arranging a plurality of secondary sub-runners, and the pouring liquid is more uniformly distributed, so that the pouring effect is better.

One end of the second-level runner is communicated with the first-level runner, and the other end of the second-level runner is inserted into a fixed mold insert 13 at the bottom end of the fixed mold plate. One end of the secondary runner is communicated with the primary runner so as to facilitate the outflow of the pouring liquid.

And the four secondary sub-runners are connected with the primary sub-runner.

And the bottom ends of the secondary branch channels 12 are provided with gates 10. And a four-point pouring gate is adopted, so that the effect of pouring the motor casing product 14 is better.

And the primary branch channels right above the secondary branch channels are provided with stripping bags which wrap the reverse buckles of the head parts of the pulling needles. And breaking the sprue in the mold opening process of the mold to separate the runner from the product.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiment according to the present invention are within the scope of the present invention.
