Description

BMC material rapid prototyping mould

Technical Field

The utility model relates to a BMC forming die technical field, concretely relates to BMC material rapid prototyping mould.

Background

Because the BMC material is thermosetting material, the product needs the shaping under high temperature to sample BMC material system, present forming die generally sets up a plurality of product shaping holes on the mould body, set up a plurality of heater strips or heating rod in the inside of mould, heat the mould body through heater strip or heating rod, and then give the product shaping hole with the heat conduction, the downthehole particulate BMC material of product shaping is heated and solidifies, form the product, however, because set up heater strip or heating rod inside the mould, it is slower to heat up one, two come to need to arrange a plurality of wire casings in the mould, the structure is not only complicated, and in case damage, also be difficult for changing. Thus, the production period is longer and the productivity is lower.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a BMC material rapid prototyping mould through the improvement to BMC material forming die, makes the intensification of mould quicker, and it is more lasting to keep warm, and then improves the production productivity.

The technical scheme of the utility model is that:

the utility model provides a BMC material rapid prototyping mould, is including the last mould and the lower mould of mutually supporting be provided with at least one product shaping hole on the lower mould, its characterized in that, still be provided with on the lower mould and place the hole, it is downthehole to place the copper sheathing, copper sheathing outer wall winding heating coil, heating coil connection heat source.

Further, the height of the copper sleeve is the same as that of the placing hole, and the inner diameter of the placing hole is matched with the outer diameter of the copper sleeve, so that the copper sleeve does not shake after being placed in the placing hole.

Furthermore, the copper sheathing is the cup type copper sheathing, and the circle that generates heat twines on the cup body of cup type copper sheathing, and after putting into the placing hole downwards at the bottom of the copper sheathing, the heater is hidden between the hole wall of cup body and placing hole. The upper edge of the copper sleeve extends outwards to form a flared edge.

Furthermore, the copper sleeve is a hollow cylindrical cup-shaped copper sleeve without a cover, two opposite straight edges are arranged on the expanded edge of the copper sleeve, and the rest are two opposite arc-shaped edges.

Furthermore, a plurality of heat dissipation holes are distributed on the upper surface of the lower die and the lower surface of the upper die.

Furthermore, a die closing guide post is further arranged on the lower die.

The utility model has the advantages that: through the heating ring on copper sheathing and the copper sheathing, can let the quick intensification of lower mould, can also let the lower mould incubation time more permanent, saved the curing time and the solidification effect of BMC material, improved production efficiency greatly.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the features of the following embodiments and examples may be combined with each other without conflict.

As shown in fig. 1-2, a BMC material rapid prototyping mould, includes an upper mould and a lower mould 1 that cooperate with each other, the lower mould 1 is provided with at least one product forming hole 2, the lower mould 1 is also provided with a placing hole 3, the placing hole 3 is used for placing a copper bush 4 therein, the outer wall of the copper bush 4 is wound with a heating ring 5, and the heating ring 5 is connected with a heat source.

In one embodiment, four placing holes 3 are formed in the lower mold 1, and the four placing holes 3 are located at four corners of a rectangle or a square and are uniformly distributed on the lower mold 1.

The height of the copper bush 4 is the same as that of the placing hole 3, after the copper bush 3 is placed in the placing hole 3, the upper surface of the edge of the copper bush 4 is just flush with the upper surface of the lower die 1, and the inner diameter of the placing hole 3 is matched with the outer diameter of the copper bush 4, so that the copper bush 4 does not shake after being placed in the placing hole 3.

The copper sheathing 4 is the cup type copper sheathing, and the heating ring 5 twines on the cup body of cup type copper sheathing, and in one embodiment, the periphery that the heating ring 5 twined copper sheathing 4 is full, has enlarged the area of contact of copper sheathing 4 with the heater like this, makes copper sheathing 4 heat up fast, puts into when copper sheathing 4 end under to the end opening up and places the hole 3 after, the heater hides between the hole wall of cup body and placing hole 3. The upper edge of the copper sleeve 4 extends outwards to form an expanded edge, the expanded edge plays a role in blocking a heating wire on the upper portion, and the copper sleeve 4 is convenient to put and take.

In one embodiment, the copper sleeve 4 is a hollow cylindrical cup-shaped copper sleeve without a cover, on one hand, the material is saved due to the hollow structure, on the other hand, the temperature rise can be accelerated, two opposite straight edges are arranged on the expanded edge of the copper sleeve 4, and the rest two opposite arc-shaped edges are arranged, so that the copper sleeve 4 can be relatively fixed in the placing hole 3, and the taking and the placing are very convenient.

A plurality of heat dissipation holes 6 are distributed on the upper surface of the lower die 1 and the lower surface of the upper die, and the heat dissipation holes can enable the heat of the lower die 1 to be rapidly exchanged and diffused between the upper die and the lower die 1.

The lower die 1 is also provided with a die assembly guide post 7, and the die assembly guide post facilitates die assembly of the upper die and the lower die 1 and plays a role in guiding and positioning.

The copper sheathing of this embodiment compares with traditional simple heater, not only installs when the lower mould, simple to operate, and still convenient the change heaies up fast moreover, can improve the production efficiency of product greatly, has still simplified the structure of mould moreover.

The above embodiments are only intended to represent the concentrated embodiments of the present invention, and the description thereof is more specific and detailed, but it is not to be understood as the limitation of the scope of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the concept of the present invention, and all of them belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
