Abstract
A kind of BMC reflector moulds of the utility model, belong to lamps and lanterns mould applications.A kind of BMC reflector moulds, increase locating convex block on sliding block, direction of the locating convex block from the contact surface of sliding block and fixed die insert toward fixed die insert protrudes out, and the fixed die insert is equipped with to be used to accommodate the locating convex block with the corresponding locating slot of the locating convex block, the locating slot.The utility model is set to the matched locating slot of the locating convex block by increasing locating convex block on sliding block, in fixed die insert so that sliding block and fixed die insert can prepare to position, to improve the installation accuracy of BMC speculums.
Description
Technical field
The utility model is related to lamps and lanterns mould applications, more particularly to a kind of BMC reflector moulds.
Background technology
BMC material is the abbreviation of Bulk molding compounds, i.e. tubular molding compound, and the country is commonly referred to as unsaturated poly-
Ester bulk the modern designs of plastics have good physical property, electrical property and mechanical property.BMC injection moulds and common thermoplasticity, thermosetting
The injection of property is somewhat different, and the mainly shrinking percentage of BMC is relatively low, and the one of only dry point.
Existing BMC speculum product generally existing side mounting structures are bad, and light distribution is unqualified.Analyzing reason is mainly：According to
It is positioned by side screw pole X/Y/Z, error requirements are in 0.1mm hereinafter, its practical BMC mold can not accomplish that reflecting surface is in cover half
Side, side screw pole is in dynamic model side, detection method difficulty.
Utility model content
The purpose of this utility model is that in view of the above-mentioned problems, provide a kind of BMC reflector moulds, it is anti-to solve BMC
Penetrate that mirror side mounting structure is bad and the underproof problem of light distribution.
What the purpose of this utility model was realized in：
A kind of BMC reflector moulds, increase locating convex block on sliding block, and the locating convex block is from sliding block and fixed die insert
The direction of contact surface toward fixed die insert protrudes out, and the fixed die insert is equipped with and the corresponding locating slot of the locating convex block, institute
Locating slot is stated for accommodating the locating convex block.
Preferably, the cross section of the locating convex block is rectangular or round.
Preferably, the rectangular quadrangle is equipped with chamfering.
Preferably, the locating convex block is integrally formed with sliding block.
The beneficial effects of the utility model are：By increasing locating convex block on sliding block, it is set in fixed die insert described
The matched locating slot of locating convex block so that sliding block and fixed die insert can prepare to position, to improve the installation of BMC speculums essence
Degree.
Description of the drawings
Fig. 1 shows a kind of internal structure chart of the BMC reflector moulds with BMC speculums of the utility model.
Fig. 2 shows the main structure figures of sliding block.
Fig. 3 shows the side block diagram of sliding block.
Fig. 4 shows a kind of internal structure chart of the BMC reflector moulds of the utility model without BMC speculums.
Wherein, 1- sliding blocks, 2- fixed die inserts, 3- model frames, 4- locating convex blocks, 5- locating slots.
Specific embodiment
With reference to specific embodiments and the drawings, the utility model is expanded on further.
As Figure 1-Figure 4, a kind of BMC reflector moulds increase locating convex block 4, the locating convex block 4 on the slider 1
It is protruded out from sliding block 1 and the direction of contact surface toward the fixed die insert 2 of fixed die insert 2, the fixed die insert 2 is equipped with and the positioning
4 corresponding locating slot 5 of convex block, the locating slot 5 are used to accommodate the locating convex block 4.
As needed, the cross section of the locating convex block 4 can be that rectangular and rectangular quadrangle is equipped with chamfering；It is described fixed
The cross section of position convex block 4 can also be circular.
For from technique, the locating convex block 4 is preferably integrally formed with sliding block 1.
The utility model adds the positioning to match in fixed die insert 2 by increasing locating convex block 4 on the slider 1
Slot 5 so that can be accurately positioned between sliding block 1 and fixed die insert 2, so as to reduce the side of BMC speculums produced by the mold
The error of the positioning stud in face.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Under the premise of the principle and essence without departing substantially from the utility model, many changes and modifications may be made,
But these change and modification each fall within the scope of protection of the utility model.
