Description

Forced demoulding type injection molding structure

Technical Field

The utility model relates to an injection moulding production technique, it is specific, its show a forced drawing of patterns formula injection moulding structure.

Background

As shown in fig. 1, the product 100 is made of PP, and includes a belt 101, and a plurality of tubes 102 are disposed on the belt 101.

The preparation of the product 100 has difficulties, the pipe body 102 comprises a vertical inner groove, but an outer pipe assembling clamping table 103 which protrudes outwards is arranged on the outer wall of the pipe body 102, so that the pipe body 102 is damaged in production, and the injection molding quality is influenced.

The abdication type forced demoulding structure is designed to be capable of effectively corresponding to the product 100 for preparation.

Therefore, it is necessary to provide a slider-combined injection molding structure to achieve the above objects.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a forced drawing of patterns formula injection moulding structure.

The technical scheme is as follows:

the utility model provides a forced drawing of patterns formula injection moulding structure, including front mould and the back mould that corresponds the setting, set up the lower corresponding groove of terminal surface under the corresponding product on the back mould, the last corresponding groove of having seted up on the front mould, and correspond the last corresponding chamber of formation corresponding product up end through the cooperation of embedding post, correspond the groove down and correspond the chamber cooperation and form embedding combination formula die cavity structure on with, it is provided with drawing of patterns subassembly to correspond on the front mould, after the shaping, the back mould carries out the die sinking earlier and dodges, the back forces the front mould to release the product through drawing of patterns subassembly, form and dodge the formula and force drawing of patterns structure.

Furthermore, an upper die cavity matched with the outer wall of the pipe body and the convex outer pipe assembly clamping table is formed in the upper corresponding cavity.

Furthermore, the end part of the embedding column is a conical pushing body, and the bottom of the conical pushing body is an upper corresponding column part which is matched with the upper die cavity to form an upper corresponding cavity.

Furthermore, the middle part of the embedded column is provided with a demoulding setting groove.

Further, the drawing of patterns subassembly is including setting up the ejecting post in drawing of patterns setting groove.

Further, the stripper assembly further comprises an auxiliary ejection post.

Furthermore, the number of the auxiliary push-out columns is two, and the auxiliary push-out columns are correspondingly arranged on two sides of the upper corresponding cavity.

Further, the mold is pushed out forcibly to be demolded, and the corresponding column parts are used as guides, so that a high-quality demolding structure is formed.

Compared with the prior art, the utility model discloses a dodge formula and force demoulding structure's settlement, the shaping back, the back mould carries out the drawing of patterns earlier and steps down, and the back corresponds the post portion for the direction through propelling out the post and supplementary propelling out the post more than, and is mandatory to release the product, guarantees the preparation efficiency and the preparation quality of product.

Detailed Description

Example (b):

referring to fig. 2-4, this embodiment shows a forced demolding type injection molding structure, which includes a front mold 1 and a rear mold 2 correspondingly disposed, a lower corresponding groove 21 corresponding to a lower end surface of a product 100 is disposed on the rear mold 2, an upper corresponding groove 11 is disposed on the front mold 1, and an upper corresponding cavity corresponding to an upper end surface of the product 100 is formed by the matching of an embedding column 3 and the upper corresponding groove 11, the lower corresponding groove 21 and the upper corresponding cavity are matched to form an embedded combined mold cavity structure, a demolding assembly 4 is correspondingly disposed on the front mold 1, after molding, the rear mold 2 is first opened and retracted, and then the product 100 is forced to be pushed out of the front mold 1 by the demolding assembly 4, so as to form an retracted forced demolding structure.

An upper die cavity 12 matched with the outer wall of the pipe body 102 and the convex outer pipe assembly clamping platform 103 is arranged on the upper corresponding cavity.

The end of the embedded column 3 is a conical pushing body 31, and the bottom of the conical pushing body 31 is an upper corresponding column part 32 which is matched with the upper die cavity 12 to form an upper corresponding cavity.

The middle part of the embedded column 3 is provided with a demoulding setting groove.

The ejector unit 4 includes an ejector pin 41 disposed in an ejector setting groove.

Stripper assembly 4 also includes an auxiliary ejection post 42.

The number of the auxiliary pushing-out columns 42 is two, and the auxiliary pushing-out columns are correspondingly arranged on two sides of the upper corresponding cavity.

The mold is forcibly pushed out and removed, and the above corresponding post portions 32 are used as guides, thereby forming a high-quality mold-removing structure.

Compared with the prior art, the utility model discloses a dodge formula and force demoulding structure's settlement, the shaping back, the back mould carries out the drawing of patterns earlier and steps down, and the back corresponds the post portion for the direction through propelling out the post and supplementary propelling out the post more, and the compulsory releases the product, guarantees the preparation efficiency and the preparation quality of product.

What has been described above is merely some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which all fall within the scope of the invention.
