AI Technical Summary
The existing ejection method of plastic molds can easily cause micro-deformation, whitening and damage to products, affecting product quality.
The inclined top synchronous core pulling demoulding structure is adopted, including the rear mold, rear mold insert, guide block and inclined top groove. The rear mold insert is fixed by screws, and the design of T-slot and inclined top groove is used to realize the sliding fit between the core pulling insert and the inclined top rod, thereby realizing compound motion demoulding.
It improves the demoulding efficiency of plastic molds, reduces micro-deformation and damage of products, and improves product quality.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to a kind of slanting ejection synchronous core-pulling demolding structure, belong to plastic mould manufacturing technical field. BACKGROUND
[0002] After plastic manufacturing, product needs to be ejected from mould, and the existing ejection mode is single, and in the ejection process, product is prone to micro deformation, white top, breakage and other phenomena, seriously affect product quality.To solve the above problems, a new technical solution is provided. SUMMARY
[0003] The present application aims to provide a kind of slanting ejection synchronous core-pulling demolding structure, to solve the problems raised in the above background.
[0004] To achieve the above object, the technical scheme adopted by the present application is as follows: a kind of slanting ejection synchronous core-pulling demolding structure, including back mould, the back mould is provided with back mould insert, guide block and slanting ejection groove, the back mould insert is fixed by screw installation on the right side of back mould top, the guide block is integrally formed and connected to the middle of back mould top, the slanting ejection groove is opened in the left side of back mould.
[0005] Preferably, T slot is formed between the guide block and back mould insert, and core-pulling insert is placed in the T slot.
[0006] Preferably, slanting ejection rod is placed in the slanting ejection groove.
[0007] Preferably, the angle between the left end of T slot and the bottom edge of back mould is 58.37 °.
[0008] Preferably, the angle between the core-pulling insert and the top edge of back mould is 31.63 °.
[0009] Preferably, the angle between the slanting ejection rod and the left end of back mould is 12 °.
[0010] Compared with the prior art, the present application has the following advantages: the back mould insert is fixed by screw installation on the right side of back mould top, and the space between back mould and mould plate can be easily filled; the core-pulling insert is placed in the T slot, which can make the core-pulling insert slide easily along the T slot; the slanting ejection rod is placed in the slanting ejection groove, which can make the slanting ejection rod slide easily along the slanting ejection groove; the above-mentioned demolding operation of plastic core can be easily carried out, and the product quality is effectively improved. BRIEF DESCRIPTION OF DRAWINGS
[0011] Fig. 1 The structure of the present application is shown in the figure;
[0012] Fig. 2 The split structure of the present application is shown in the figure;
[0013] In the figure: 1-rear mold; 2-rear mold insert; 3-guide block; 4-oblique ejector groove; 5-T groove; 6-core pulling insert; 7-oblique ejector rod. DETAILED DESCRIPTION
[0014] The technical solutions in the embodiments of the present invention will be clearly and completely explained below with reference to the accompanying drawings in the embodiments of the present invention.
[0015] like Figs. 1-2 As shown, a slanted top synchronous core-pulling demolding structure includes a rear mold 1, on which a rear mold insert 2, a guide block 3 and a slanted top groove 4 are provided. The rear mold insert 2 is fixed to the right side of the top of the rear mold 1 by screws, and the guide block 3 is integrally formed and connected to the middle of the top of the rear mold 1. The slanted top groove 4 is opened on the left side of the rear mold 1. A T-slot 5 is formed between the guide block 3 and the rear mold insert 2, a core-pulling insert 6 is placed in the T-slot 5, and a slanted top rod 7 is placed in the slanted top groove 4. The angle between the left end of the T-slot 5 and the bottom edge of the rear mold 1 is 58.37°, the angle between the core-pulling insert 6 and the top edge of the rear mold 1 is 31.63°, and the angle between the slanted top rod 7 and the left end of the rear mold 1 is 12°.
[0016] Specific usage: When the plastic product needs to be ejected after injection molding, the core-pulling insert 6 slides along the T-slot 5, and the inclined ejector rod 7 slides along the inclined ejector slot 4. The two components perform a compound motion at the same time to achieve core-pulling and release in different movement directions on the inclined ejector. The reset process is the opposite compound motion return.
[0017] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
