Technical Field

The utility model relates to a take off the material device, in particular to high accuracy mould takes off material device belongs to mould equipment technical field.

Background

With the rapid development of economy today, market demands for various industrial products are currently being faced. The size precision of the product of the client is continuously improved, and the size of the product is ensured by the mold. The higher the demand for high precision products, the higher the demand for molds.

However, in the prior art, the conventional die stripping adopts stripping nails or stripping blocks, which do not strip at the bent or deep-drawn part of the product, and the conventional stripping is at the edge of the product, which can cause the product to deform or have unstable size in the stripping process, thus causing difficulty to the production precision and severely restricting the precision and the production efficiency of the product.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a high precision mould takes off material device, through the design to the mould structure, through the material piece of taking off that increases in the mould, makes it play and takes off material and limiting displacement, can not lead to product deformation and dimensional deviation because of taking off the material reason, and the effectual personnel debugging time that has reduced.

In order to solve the technical problem, the technical scheme of the utility model provides a high-precision mold stripping device, including stripping block, stripping spring and the thimble that sets up between cope match-plate pattern and cope match-plate pattern, set up the lower mould entering piece that matches with the product of waiting to punch in the punching press recess of cope match-plate pattern, the product of waiting to punch is placed at the top of lower mould entering piece, be equipped with at the lower extreme of lower mould entering piece and supply the cavity of stripping block up-and-down motion, stripping spring is installed to stripping block bottom; the upper end of the ejector pin is arranged on an upper die stripper plate of the upper die plate, and the lower end of the ejector pin penetrates into the stamping groove to be abutted against the stripper block.

The utility model discloses a further inject technical scheme, aforementioned secondary forming's external mold positioner, the thimble supports to take off the material piece and pushes down the degree of depth and take the punching press product punching press degree of depth the same to the realization is taken off the flitch and is driven the product and can be taken off the material in step, does not take place to interfere.

In the secondary forming external mold positioning device, the middle part of the stripping block is provided with an upward protruding part, the upward protruding part is matched with an inner punch warp of a product to be punched, the outer diameter of the protruding part is smaller than that of the stripping block, and the width of a step between the protruding part and the stripping block is larger than the thickness of the plate with the punched product. The product can provide certain support when stamping forming, can prevent the product deformation when taking off the material.

Further, in the above-mentioned secondary forming external mold positioning device, the lower end of the stripping block is provided with a guide plate, and the guide plate moves up and down along the cavity at the lower end of the lower mold insert block; the ejector pins are symmetrically distributed on the guide plates on the periphery of the stripping block, so that the verticality of the operation of the stripping block can be effectively guaranteed, the phenomenon that the material is blocked or the size of a product is changed due to stroke deviation is avoided, and the quality stability of the product is improved.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the scheme of the application is mainly used for stations which have high requirements on bending and deep drawing products and cannot finish conventional stripping. Because the conventional die stripping adopts stripping nails or stripping blocks, the stripping is not carried out at the bent or deep-drawn part of the product, and the conventional stripping is carried out at the edge of the product, the outer edge of the product is deformed or the size of the product is unstable in the stripping process, so that the production control is difficult. The design device not only meets the delivery of product quality and productivity, but also meets the advantage of market project occupancy, and the structure effectively solves the problems of instability, material jamming, size variation and the like in the die; the production process is not stopped, and the personnel are not overhauled.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The embodiment discloses a high-precision mold stripping device, which is structurally shown in fig. 1-4 and comprises a stripping block 1, a stripping spring and an ejector pin 4, wherein the stripping block 1, the stripping spring and the ejector pin 4 are arranged between a lower template 2 and an upper template, a lower mold insert matched with a product to be stamped is arranged in a stamping groove of the lower template 2, the product 6 to be stamped is placed at the top of the lower mold insert 5, a cavity for the stripping block 1 to move up and down is arranged at the lower end of the lower mold insert 5, and the stripping spring 6 is arranged at the bottom of the stripping block 1; the upper end of the thimble 4 is arranged on an upper mould stripper plate 3 of the upper mould plate, and the lower end of the thimble 4 penetrates into the stamping groove to be abutted against the stripper block 1.

The pressing depth of the thimble 4 against the stripping block 1 is the same as the punching depth of the product 6 with the punching; the middle part of the stripping block 1 is provided with an upward convex part 12 which is matched with the inner diameter of the product to be punched. The outer diameter of the convex part 12 is smaller than that of the stripping block 1, and the width of the step 11 between the convex part and the stripping block 1 is larger than the thickness of a plate with a punching product. The lower end of the stripping block 1 is provided with a guide plate 13, and the guide plate 13 moves up and down along the cavity at the lower end of the lower die feeding block 5; the thimble 4 is distributed on the guide plate 13 around the stripping block 1 in a symmetrical mode.

The working principle is as follows: when the device is used, a blank is placed on a lower die feeding block 5, a die is started to press, a stripping block 1 is synchronously pressed down along with an upper die of a stamping die under the action of a thimble 4 in the forming process, and a product is supported by a convex part of the stripping block 1; when the upper die plate reaches the lower dead point, the upper die plate returns upwards, the stripping block 1 moves upwards along with the upper die plate under the action of the stripping spring 6, the punched product is lifted by the convex part and the step of the stripping block 1, and when the upper die plate reaches the highest point, stripping of the product is finished immediately. The material piece 1 of taking off in this application scheme has played and has taken off material and limiting displacement, because the advantage of taking off the 1 structure of material piece, can not lead to product deformation and size deviation because of the reason of taking off the material, and the effectual personnel debugging time that has reduced, the production process is stable to the efficiency in time and the promotion of productivity have been improved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
