Abstract
The invention relates to a pouring mold for an outer barrel of a dust collector. The pouring mold comprises a lower mold base, wherein a lower mold groove is formed in the lower mold base and is fixedly connected with sliding rails; a lower mold hole is formed in the bottom surface of the lower mold groove; a mold core is arranged in the lower mold hole; brackets are fixedly connected with two ends, positioned on the lower mold groove, of the lower mold base; a cylinder is arranged on each bracket; push rods of the cylinders are connected with a left mold base and a right mold base which are arranged in the lower mold groove; the opposite side walls of the left mold base and the right mold base are arc-shaped; pouring gates are arranged at the tops of the left mold base and the right mold base; a gap is formed between each of the opposite side walls of the left mold base and the right mold base and the mold core, and is communicated with the corresponding pouring gate; sliding holes are formed in the side walls, positioned on the sliding rails, of the left mold base and the right mold base; core pulling blocks are positioned in the sliding holes and are supported on the sliding rails; a pull rod is arranged aslope on each core pulling block; a T-shaped groove is formed in one end part of each core pulling block; a pulling pin is vertically arranged in each T-shaped groove; mold pins are arranged in the left mold base and the right mold base along the parallel direction of the sliding rails. The pouring mold for the outer barrel of the dust collector is simple in structure, high in core pulling efficiency and high in reliability; the product quality is easily guaranteed.
Description
Technical field
The present invention relates to technical field of mold, be specifically related to the casting mold for the production of dust catcher outer barrel.
Background technology
Dust catcher is small household appliances common in daily household, its outer barrel is working of plastics, conventionally all complete by plastics injection mould injection moulding, also there is larger impact to the quality of product in the efficiency that the design of mould structure directly has influence on mould core pulling simultaneously, although mould structure can complete and loose core smoothly now, but efficiency is low, poor reliability easily causes the quality problems of outer barrel.
Summary of the invention
The applicant improves for above-mentioned shortcoming of the prior art, and a kind of dust catcher outer barrel casting mold is provided, and it is simple in structure, and the efficiency of loosing core is high, and good reliability easily guarantees product quality.
Technical scheme of the present invention is as follows:
A kind of dust catcher outer barrel casting mold, comprises die shoe, on die shoe with lower die cavity, the both sides of the described lower die cavity slide rail that is connected, the bottom surface of described lower die cavity, with lower nib, is provided with core rod in described lower nib; The two ends that die shoe is positioned at described lower die cavity are fixed with support, cylinder is installed on support, the push rod of cylinder is connected with right die holder with the left die holder being arranged in described lower die cavity, the sidewall that left die holder is relative with right die holder is all curved, the top of left die holder and right die holder is provided with cast gate, on cast gate, with sprue gate, between the described sidewall that left die holder is relative with right die holder and core rod, have gap, described gap communicates with sprue gate; Left die holder and right die holder are positioned at the sidewall of slide rail all with slide opening, and the piece of loosing core is positioned at described slide opening and is supported on slide rail, tilting pull bar on the piece of loosing core, and loose core piece and pull bar are slidably matched; Loose core piece end with T-slot, at right angle setting pumping pin in described T-slot; In left die holder and right die holder, along slide rail parallel direction, mould pin is installed.
Technique effect of the present invention:
The present invention is simple in structure, and the efficiency of loosing core is high, good reliability and there will not be quality problems in the time loosing core, and production efficiency and quality all easily guarantee.
Accompanying drawing explanation
Fig. 1 and Fig. 2 are the structural representation of product (dust catcher outer barrel).
Fig. 3 to Fig. 5 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1 to Fig. 5, the present invention includes die shoe 2, on die shoe 2 with lower die cavity, the both sides of the described lower die cavity slide rail 9 that is connected, the bottom surface of described lower die cavity, with lower nib, is provided with core rod 13 in described lower nib, core rod 13 is for generating the inner chamber of product; The two ends that die shoe 2 is positioned at described lower die cavity are fixed with support 5, cylinder 8 is installed on support 5, the push rod of cylinder 8 is connected with right die holder 3 with the left die holder 4 being arranged in described lower die cavity, start cylinder 8 can the left die holder 4 of push-and-pull and right die holder 3 in described lower die cavity, slide along slide rail 9, realize matched moulds or mold closing; The sidewall that left die holder 4 is relative with right die holder 3 is all curved, the structure of described sidewall is corresponding with the structure of circle product external, left die holder 4 is provided with cast gate 6 with the top of right die holder 3, on cast gate 6 with sprue gate 61, between the described sidewall that left die holder 4 is relative with right die holder 3 and core rod 13, there is gap, described gap communicates with sprue gate 61, is injected and is watered material by sprue gate 61, waters material and be packed in described gap described in can making; The sidewall that left die holder 4 and right die holder 3 are positioned at slide rail 9 is all with slide opening, the piece 10 of loosing core is positioned at described slide opening and is supported on slide rail 9, the tilting pull bar 12 on piece 10 of loosing core, the piece 10 of loosing core is slidably matched with pull bar 12, and described pull bar 12 is connected with upper bolster (China does not draw), when described upper bolster is upwards when parting, can drive upwards translation of pull bar 12, pull bar 12 is due to oblique setting, and the piece 10 of movably loosing core applies the effect of horizontal force, and piece 10 translation on slide rail 9 can make to loose core; Loose core piece 10 ends with T-slot, at right angle setting pumping pin 11 in described T-slot, pumping pin 11 is identical with the piece of loosing core on two wood side-guides 9, be paired setting, in the time of matched moulds, two pumping pin 11 ends are in opposite directions nearest, can be used to generate the pin-and-hole on circle product external U-shaped connecting portion 15 or connecting portion 14; Left die holder 4 is provided with mould pin 7 with right die holder 3 is interior along slide rail 9 parallel directions, the end band of mould pin 7 is fluted, the structure of described groove is corresponding with the connecting portion structure on circle product external, and for generating the connecting portion on circle product external, mould pin 7 is with left die holder 4 and 3 motions of right die holder;
The principle of loosing core of the present invention is as follows:
When matched moulds state, sprue gate 61 from cast gate 6 is injected and is watered material, describedly water material and enter the gap of formation between described sidewall that left die holder 4 is relative with right die holder 3 and core rod 13, after filling, first start upper bolster, and then drive the upwards translation of pull bar 12 of loosing core on piece 10, pull bar 12 applies the effect of horizontal force to the piece 10 of loosing core, the loose core pumping pin 11 of piece 10 ends of drive outwards moves, restart cylinder 8, make it pull left die holder 4 and right die holder 3 from motion, extract out from the circle product external connecting portion of producing with dynamic model pin 7 simultaneously, finally realize the smooth demoulding, obtain required product.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
