Abstract
The utility model provides a cover mould utensil behind audio amplifier, includes cover half, movable mould and core, cover half and movable mould phase -match, be provided with in the cover half with core assorted die cavity, the core towards cover half one side is seted up flutedly, be equipped with in the recess with the movable block that recess inside dimension is the same, the movable block can remove at the recess, adjusting screw is worn to be equipped with with the inconsistent one side of movable mould by the core, the die cavity towards position that the groove phase corresponds be provided with with the shaped block that the groove phase matches. Simultaneously, after the position control of movable block finished, the screw rod can be fixed the movable block again, in addition the shaped block of matching. Thereby, just the recess of an appointed thickness can be produced at the in -process of moulding plastics very lightly, and then the utilization ratio of mould has been improved, also can avoid the audio amplifier and then to install and use produced trouble.
Description
Technical field
The utility model relates to a kind of field of machining, particularly relates to a kind of audio amplifier rear cover mould.
Background technology
Mould, in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts, and it realizes the processing of article profile mainly through the change of institute's moulding material physical state.
For most audio amplifier, their some position must offer the groove for installing all kinds of by-pass cock.But most mould all can not be arranged according to the arrangement of audio amplifier internal hardware and the reason such as raw-material characteristic and thickness bottom adjusting grooves.Thus, be unfavorable for installation and the use of following audio amplifier.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of injection moulding thickness adjustable audio amplifier rear cover mould.
For achieving the above object, the utility model provides following technical scheme: a kind of audio amplifier rear cover mould, comprise cover half, dynamic model and core, cover half and dynamic model match, the die cavity matched with core is provided with in cover half, described core plan offers groove to described cover half side, the movable block measure-alike with described inside grooves is provided with in described groove, described movable block can move at groove, described core and the inconsistent one side of dynamic model are equipped with adjusting screw(rod), and described cavity surface is provided with the shaped block with described groove match to the position that described groove is corresponding.
As preferably, described shaped block in the resistance surface of described die cavity be provided with along shaped block edge ring around cooling water flow conduits.
As preferably, described cooling water flow conduits extends and is provided with cooling chamber in described shaped block.
As preferably, described screw rod is three, and does not become same straight line to be arranged on described movable block.
As preferably, described dynamic model is provided with thimble around described core, the diameter of described thimble in described core side is less than the diameter of described thimble opposite side.
The utility model has following advantage: under the turning effort of screw rod, and movable block can move along groove.Meanwhile, after the position adjustments of movable block, screw rod can be fixed movable block again, adds the shaped block of coupling.Thus, in injection moulding process, just can produce the groove of an appointed thickness very like a cork, and then improve the utilization rate of mould, audio amplifier also can be avoided next to install and use produced trouble.
In addition, cooling water flow conduits and being provided with of cooling chamber are beneficial to the sizing after accelerating injection moulding, make the product structure after sizing parting not easily deformation occur, and the distribution of three different straight lines of screw rod is provided with the horizontal stability being beneficial to and improving movable block, makes the more standard of the groove after injection moulding.Meanwhile, what thimble two ends size was different arranged can reduce product on the one hand and printed by issuable pushing tow in pushing tow process, and another aspect can avoid thimble bend in pushing tow process or fracture.

Detailed description of the invention
Referring to figs. 1 through Fig. 6, the utility model embodiment is described further.
A kind of audio amplifier rear cover mould of the utility model, comprise cover half 1, dynamic model 3 and audio amplifier bonnet core 2, cover half 1 and dynamic model 3 match, the die cavity 11 matched with core 2 is provided with in cover half 1, audio amplifier bonnet core 2 offers rectangular recess 4 in cover half 1 side, the shape of groove 4 can need according to specific product and arrange herein, and the inside of groove 4 is provided with the movable block 5 matched with groove 4 inside dimension, and movable block 5 can be mobile along groove 4 inside.Audio amplifier bonnet core 2 is equipped with adjusting screw(rod) 7 in dynamic model 3 side, and screw rod 7 is vertically installed in movable block 5 plane, can regulate the position of movable block 5 in groove 4 by the rotation of screw rod 7, can be fixed again to movable block 5 meanwhile.Die cavity 11 is provided with the shaped block 6 matched with groove 4 size in the position corresponding to groove 4, be conducive to the groove injecting appointed thickness by shaped block 6 with movable block 5 work of matching.
Further scheme is, shaped block 6 one side inconsistent with die cavity 11 is provided with cooling water flow conduits 8, cooling water flow conduits 8 is surrounded on shaped block 6 surrounding and arranges, cooling water flow conduits 8 has cooling chamber 9 to shaped block 6 is inner extended, such one side is conducive to the cross section that cooling water flows through shaped block 6 as far as possible, also be conducive to the space of cooling water residing for shaped block 6 inside on the other hand enough large, and then improve speed and the quality of audio amplifier bonnet injection moulding aftershaping.
Further scheme is, the number of screw rod 7 is three, and the position arranged is not on the same line, because determine the principle of a plane, thus is conducive to the horizontal stability improving movable block 5 at 3, and then improves Forming Quality and the aesthetics of audio amplifier bonnet.
Further scheme is, dynamic model 3 is provided with thimble 10 along the surrounding of audio amplifier bonnet core 2, thimble 10 contacts at audio amplifier bonnet core 2, thimble 10 in the side diameter of audio amplifier bonnet core 2 be 2cm, the diameter of thimble 10 in dynamic model 3 side is 4cm, thus namely can reduce audio amplifier bonnet core 2 when parting by the area of pushing tow, reduce the pushing tow print that audio amplifier bonnet may occur, can prevent again because thimble 10 is meticulous, and there is the accidents such as thimble 10 is bending, fracture, substantially increase the production efficiency of audio amplifier bonnet.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
