Description

Brake chamber dirt-proof boot mould
Technical field
The utility model relates to a kind of mould, specifically a kind of brake chamber dirt-proof boot mould.
Background technology
Existing brake chamber dirt-proof boot mould mostly is made of two parts, after finishing, production is difficult for from mould, taking out, and the accuracy of mould location is not high during pressing, the phenomenon that occurs bias voltage easily, the dirt-proof boot that produces is in uneven thickness, product quality is uneven, defect rate is higher, for addressing this problem, those skilled in the art designs the brake chamber dirt-proof boot mould that is made of three parts, product can be taken out from mould easily, and come middle mould is positioned, prevent the situation of bias voltage by positioning elements such as alignment pins, but when using, this mould needs a plurality of alignment pins accurately just can be carried out pressing mold behind the aligning, required precision to calibration steps is too high, and production efficiency is low, is not therefore applied.
Summary of the invention
The purpose of this utility model provides a kind of brake chamber dirt-proof boot mould, and it is made of three parts, is convenient to product is taken out from mould, and can accurately locatees between the each several part mould, guarantees product quality, and positioning action is convenient, does not need accurate calibration.
The utility model for achieving the above object, be achieved through the following technical solutions: comprise upper die and lower die and central shaft, middle part, patrix bottom surface is provided with arc-shaped concave, the concave surface top center is provided with first circular hole, the junction of the concave surface and first circular hole is provided with annular groove, the counterdie middle part is provided with second circular hole, the central shaft bottom is first cylinder, the first cylinder top is provided with the circular arc convex surface, the convex surface top center is provided with second cylinder, the first cylindrical diameter D4 equals the diameter D3 of second circular hole, and the second cylindrical diameter D2 equals the diameter D1 of first circular hole.The height H 1 of patrix and height H 2 sums of counterdie equal the height H 3 of central shaft.The patrix bottom surface is provided with opens die cavity.The second circular hole top sides of counterdie is along offering the excessive glue groove of annular.
Advantage of the present utility model is: reasonable in design, and it is convenient to take out product, and the location is accurate, and good product quality is easy to operate, and is lower to the calibration accuracy requirement, helps enhancing productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of the utility model patrix 1; Fig. 3 is the structural representation of the utility model counterdie 2; Fig. 4 is the structural representation of the utility model central shaft 3.
The specific embodiment
Brake chamber dirt-proof boot mould described in the utility model comprises patrix 1, counterdie 2 and central shaft 3, middle part, patrix 1 bottom surface is provided with arc-shaped concave 4, concave surface 4 top center are provided with first circular hole 5, the junction of the concave surface 4 and first circular hole 5 is provided with annular groove 6, counterdie 2 middle parts are provided with second circular hole 10, central shaft 3 bottoms are first cylinder 7, first cylinder, 7 tops are provided with circular arc convex surface 8, convex surface 8 top center are provided with second cylinder 9, the diameter D4 of first cylinder 7 equals the diameter D3 of second circular hole 10, and the diameter D2 of second cylinder 9 equals the diameter D1 of first circular hole 5.Mould adopts three parts to constitute, and only needs after finished product completes patrix 1 is separated with counterdie 2, just can easily finished product be taken out.Wherein concave surface 4, groove 6 and convex surface 8 are that first circular hole 5 and second circular hole 10 are used for central shaft 3 is positioned according to the configuration design of the dirt-proof boot of producing.During use, earlier patrix 1 and counterdie 2 are fastened, after inserting rubber, again central shaft 3 is pressed into by second circular hole, 10 places, because the diameter of second cylinder 9 on central shaft 3 tops is far smaller than the diameter of second circular hole 10, therefore less to the required precision of central shaft 3 position corrections, even the position of central shaft 3 is deviation to some extent, as long as second cylinder 9 can enter second circular hole 10, just can be along arc-shaped concave 4 automatic correction positions, till second cylinder 9 enters first circular hole, 5, the first cylinders 7 and enters second circular hole 10, because the diameter D4 of first cylinder 7 equals the diameter D3 of second circular hole 10, the diameter D2 of second cylinder 9 equals the diameter D1 of first circular hole 5, therefore can guarantee that central shaft 3 is in center position this moment, can not be offset, thereby the thickness of guaranteeing the dirt-proof boot produced is even.
In order to prevent that the utility model central shaft 3 from compressing excessively, cause the product sidewall thin excessively, the height H 1 that can make patrix 1 when making mould and height H 2 sums of counterdie 2 equal the height H 3 of central shaft 3.After central shaft 3 compactings put in place, top and bottom all flushed with patrix 1 and counterdie 2, can't further compress, and therefore can prevent effectively that central shaft 3 from compressing excessively, guaranteed product quality.
The utility model takes out from mould in order further to be convenient to finished product, can be provided with in patrix 1 bottom surface and open die cavity 11.Mould is bonding tighter if production is finished the back, inserts to open in the die cavity 11 patrix 1 and counterdie 2 pried open with instrument to get final product.According to actual needs, open the end face that die cavity 11 can be arranged on counterdie 2.
The utility model can be offered the excessive glue groove 12 of annular on second circular hole, the 10 top sides edge of counterdie 2 in order to prevent owing to filler too much influences finished size.When filler was too much, unnecessary rubber can be pressed against glue groove 12 places of overflowing, and does not influence finished size, has further guaranteed product quality.
