Description
Technical field
The present invention relates to injection molding arts, more particularly to a kind of for injection mold and for the Hough of the injection mold
Block.
Background technology
Screw thread product is otherwise a kind of widely used plastic products can because screw thread product cannot be ejected directly by force
Thread shape is destroyed, therefore just needs to design the mechanism for capableing of perfect abjection screw thread.Existing injection mold usually can cope with
The demoulding of single or double screw thread product, but when product has inside and outside three face coaxial threaded demand, it is necessary to use three emaciated face films
Injection mold, this kind of injection mold is usually made of upper cover half part, lower dynamic model part and left and right core pulling part.When demoulding,
Upper cover half part first detaches the top surface demoulding for realizing product, and left and right core pulling part is by half_split block to both sides are taken out to left and right respectively
It draws, realizes that product side surface demolding, lower dynamic model part eject product, the final whole demoulding for realizing product.So far, due to
Structure and action are complicated, and the injection mold for producing this kind of product only has a cavity per mould, theoretically analyzes, due to right/left pull direction
On limitation, at die joint use half_split block when, be at most also only possible to realize one row's chamber of a mould, low production efficiency；
As soon as also someone is considered as multiple inclined guide pillars and drives the polylith half_split block movement realization multiple rows of chamber of mould respectively, this is needed
Multiple inclined guide pillars, and inclined guide pillar quantity is excessive, can seriously affect mould inside layout, causes inner space insufficient, to not have
It is with practical value.
Invention content
The purpose of the present invention is to solve above-mentioned technical problem, provide that a kind of structure is extremely simple, does not change existing note
The main structure of mould, the interior layout for not influencing plastic mould, it is easily operated, can quick nondestructive demoulding, greatly improve production
The double lumen pore combined type half_split block of efficiency.
The present invention also provides a kind of injection molds using above-mentioned double lumen pore combined type half_split block.
The double lumen pore combined type half_split block of the present invention includes left substrate and right substrate, and the left substrate includes a left side from left to right
Withdrawing part, the first half cavity portion A and the second half cavity portion A are fixed on withdrawing part on the left of the first half cavity portion A, and right side passes through
Left interconnecting piece is connect with the second half cavity portion A, and the right edge of the first half cavity portion A and the second half cavity portion A are equipped with multiple left half
Lumen pore；The right substrate right-to-left includes right withdrawing part, the second half cavity portion B and the first half cavity portion B, the second half cavity portion B's
Right side is fixed on right withdrawing part, is passed on left right interconnecting piece and is connect with the first half cavity portion B, the second half cavity portion B and first
The left side of half cavity portion B is equipped with multiple right half lumen pores corresponding with the left half cavity hole；The left interconnecting piece and right interconnecting piece
It is connected by sliding equipment, and the second half cavity portion A of left substrate are placed exactly in the second half cavity portion B and the first half cavity portions of right substrate
Between B, the first half cavity portion B of right substrate are placed exactly between the first half cavity portion A of left substrate and the second half cavity portion A；Described first
The left half cavity hole of half lumen pore of the right side of the left half cavity hole of half cavity portion A and the first half cavity portion B and the second half cavity portion A and the second half chambers
Half lumen pore of the right side of portion B correspond to it is combined and spliced after can form double complete lumen pore.
Spacing between the left side of the second half cavity portion A and the right edge of the first half cavity portion B is pull spacing, is big
In the straight hole of lumen pore.
The sliding equipment is the structure that sliding block and sliding slot coordinate.
The injection mold of a multi-cavity mold synchronous forming of the present invention demoulding, including upper cover half part, lower dynamic model part and left and right
Core pulling part is equipped with above-mentioned double lumen pore combined type Hough at the die joint between the upper cover half part and lower dynamic model part
Block, the left core pulling part connect the left withdrawing part of the left substrate of the double lumen pore combined type half_split block, the right core pulling portion
Divide the right withdrawing part of the right substrate of the connection double lumen pore combined type half_split block.
The present invention is directed to the problem of background technology, is improved existing Hough block structure, two pieces of left and right
It is all respectively provided with two half cavity portions for being equipped with half lumen pore on substrate, after two pieces of substrates staggeredly splice, makes the second half cavity portion A of left substrate
It is placed exactly between the second half cavity portion B of right substrate and the first half cavity portion B, the first half cavity portion B of right substrate are placed exactly in left base
Between the first half cavity portion A of plate and the second half cavity portion B, left half cavity hole and right half lumen pore are just combined into complete lumen pore, double from making
Lumen pore is implemented as possibility；In order to solve the problems, such as that demoulding, two substrate splicing rear left interconnecting pieces and right interconnecting piece just correspond to,
The two can be attached by sliding equipment at this time, and in demoulding, left and right substrate is distinguished pull to left and right, then sliding equipment
It can guarantee the smooth sliding along pull direction of left and right substrate, while being also that draw process is oriented to and limits, in molding,
Convenient for the rapid accurately split again of left and right substrate.
The structure of the sliding equipment is not particularly limited, and those skilled in the art can be rationally arranged as needed, preferably
One or more groups of sliding blocks and sliding slot is such as respectively set in the structure coordinated using sliding block and sliding slot on left and right interconnecting piece, corresponding real
Being slidably matched between existing left and right substrate.
Spacing between the left side of the second half cavity portion A and the right edge of the first half cavity portion B is pull spacing, preferably
For the straight hole more than lumen pore.To ensure that half_split block can be sufficiently disengaged from product in demoulding left and right core pulling, ensure demoulding effect,
If spacing is too small, local demoulding may be caused incomplete.
Advantageous effect：
1. half_split block of the present invention has double lumen pore, meet the needs of the double chamber of a mould, more existing a cavity per mould or one
The single chamber of mould, which is compared, can greatly improve production efficiency.
2. half_split block of the present invention can be used in the synchronous forming demoulding injection mold of existing three emaciated faces mould, do not change existing mold
Primary structure, do not influence cloth space layout, can fast demoulding and laminating adhesive.
3. injection mold of the present invention can realize double chamber synchronous forming demoulding, production efficiency is high, is suitable in production such as
The screw thread product product of outer three faces coaxial threaded demand has large-scale production value.
