Problems solved by technology

[0002] Foaming molds are generally guided by setting guide posts and guide sleeve structures on the mold base. The matching accuracy of the guide post and guide sleeve structures is generally controlled at a unilateral gap of 0.07-0.08mm, and the guide accuracy is relatively low, which belongs to coarse guide. , has a certain impact on the quality of the foamed product
If the matching accuracy is high, it is easy to cause the guide post and guide sleeve to be stuck

Embodiment Construction

[0006] Firstly, process the guide post and guide post of the formwork: process the guide clearance of the formwork guide post and guide sleeve to the precision guide fit required by the mold design, and the fine guide fit precision is unilateral clearance 0.01-0.02mm.

[0007] Rectangular upper and lower fine positioning wear-resistant blocks whose sides can cooperate and guide each other are respectively installed on the upper die and the lower die of the mold. The size of the upper and lower fine-position wear-resistant blocks is the theoretical design size.

[0008] Replace the fine positioning wear-resistant block of the lower mold of the mold with an aluminum simulated positioning block whose material is easy to cut, and the size of the aluminum simulated positioning block is slightly larger than the theoretical design size.

[0009] Utilize the guidance of the guide pillars and guide sleeves of the mold frame, and the mold is clamped by the press, so that the upper precis...

Abstract

The invention relates to a precise-guide die arrangement process for an auto interior ornament moulding mould. The guide clearance of a mould frame guide post and a guide sleeve is processed to precise-guide coordination precision required by mould design; an upper precise positioning wearable block and a lower precise positioning wearable block are arranged on an upper mould and a lower mould ofthe mould; the precise positioning wearable block of the lower mould of the mould replaces an aluminium simulated positioning block; the aluminium simulated positioning block with precise-guide coordination precision is obtained by punching through the guidance of the mould frame guide post and the guide sleeve, and the lower precise positioning wearable block is processed according to the size; the precise-guide coordination precision of the mould is realized through the cooperation of the upper precise positioning wearable block and the lower precise positioning wearable block; and the mould frame guide post and the guide sleeve are processed to crude-guide coordination precision. The process has the advantages that: the precise-guide upper precise positioning wearable block and the precise-guide lower precise positioning wearable block are obtained through the punching of the mould frame guide post and the guide sleeve which have precise-guide coordination precision, the mould frame guide post and the guide sleeve are processed to crude-guide coordination precision, precise guidance of the upper precise positioning wearable block and the lower precise positioning wearable blockare realized through the crude guidance of the mould frame guide post and the guide sleeve, and the quality of a foaming product is ensured.

Description

technical field [0001] The invention relates to a mold matching process, in particular to a fine-guiding mold matching process for forming molds for automotive interior parts. Background technique [0002] Foaming molds are generally guided by setting guide posts and guide sleeve structures on the mold base. The matching accuracy of the guide post and guide sleeve structures is generally controlled at a unilateral gap of 0.07-0.08mm, and the guide accuracy is relatively low, which belongs to coarse guide. , has a certain impact on the quality of the foamed product. If the matching accuracy is high, it is easy to cause the guide post and guide sleeve to be stuck. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a precision guide mold matching process for forming molds for automotive interior parts with high guide precision and is not easy to be stuck. [0004] In order to solve the above-mentioned technical probl...
