Abstract

The utility model discloses a large slide block structure for preventing a product from burring. The molded product is large in finishing surface. The structure comprises a female die body, a male die body and a large slide block, wherein the male die body is combined with the female die body to form the product; the large slide block is arranged between the male die body and the female die body so as to form the larger finishing surface of the product; an insert broken parting surface is formed between the large slide block and the male die body. Compared with the prior art, the large slide block structure for preventing product from burring has the advantages that because the insert broken parting surface is formed between the large slide block and the male die body, even if the large slide block is subjected to high forming pressure during injection molding, the large slide block is impacted to retract, a gap generated by the insert broken parting surface between the large slide block and the male die body is small, and plastics are prevented from entering the gap. Therefore, the product is prevented from burring.

Description

Prevent that product from going out the large-scale slide block structure of burr

[technical field]

The utility model relates to a kind of large-scale slide block structure, particularly relates to a kind ofly preventing that product from going out the large-scale slide block structure of burr.

[background technology]

Plastic cement products, in the time of ejection formation, can use slide block structure.Refer to Fig. 1, Fig. 2, Fig. 1 illustrates the structural representation into a kind of plastic cement products, and Fig. 2 illustrates the partial structurtes schematic diagram into the mould prior art of plastic cement products in Fig. 1.

As shown in Figure 1, described product 10 comprises that have need to be by large whole of slide block moulding, and the size of described product 10 is large (being for example 590mm*370mm*60mm as shown in the figure).As shown in Figure 2, this product 10 is by mother module core 11, male die

core

12 and 13 moulding of large-scale slide block, wherein, and described in described large-scale slide block 13 moulding one large whole of product 10.Between described large-scale slide block 13 and described male die core 12, adopt breaking die joint to be in contact with one another.Certainly, this structure also can have slide block bundle piece (not shown) described large-scale slide block 13 is tightened.

But, adopt said structure, because the size of described product 10 is larger, in the time of ejection formation, described large-scale slide block 13 can be subject to larger briquetting pressure, even if there is slide block bundle piece, described large-scale slide block 13 or meeting are impacted be retreated, breaking die joint between described large-scale slide block 13 and described male die core 12 still can produce gap, and then plastic cement enters between described large-scale slide block 13 and described male die core 12, on described product 10, forms burr.

In view of this, be necessary to develop a kind of large-scale slide block structure in fact, to address the above problem.

[summary of the invention]

Therefore, the purpose of this utility model is to provide and a kind ofly prevents that product from going out the large-scale slide block structure of burr, solve while adopting large whole of large-scale slide block shaped article, between the breaking die joint between die and large-scale slide block, occur gap, thereby on product, form the problem of burr.

In order to achieve the above object, what the utility model provided prevents that product from going out the large-scale slide block structure of burr, large whole of shaped article, and this structure comprises:

Mother module core;

Male die core, with product described in described mother module core connecting shaping;

Large-scale slide block, is located between described male die core and described mother module core, and large whole of product described in moulding has between described large-scale slide block and described male die core to insert and break die joint.

Optionally, between described large-scale slide block and described male die core, also there is vertical contact-making surface, the described vertical contact-making surface described broken die joint of inserting that continues.

Optionally, inserting between described large-scale slide block and described male die core broken die joint in the time of injection mo(u)lding, and the gap producing is less than 0.03 millimeter.

Compared to prior art, utilize and of the present utility modelly prevent that product from going out the large-scale slide block structure of burr, insert broken die joint owing to adopting between described large-scale slide block and described male die core, even large-scale slide block can be subject to larger briquetting pressure described in therefore in the time of injection moulding, described large-scale slide block can be impacted to be retreated, the gap that slotting broken die joint between described large-scale slide block and described male die core produces is less, can not make plastic cement enter, and therefore product can not form burr.

Fig. 1 illustrates the structural representation into a kind of plastic cement products.

Fig. 2 illustrates the partial structurtes schematic diagram into the mould prior art of plastic cement products in Fig. 1.

Fig. 3 illustrates as of the present utility model and prevents that product from going out the structural representation of large-scale slide block structure one preferred embodiment of burr.

[detailed description of the invention]

Incorporated by reference to consulting Fig. 1, Fig. 3, Fig. 3 illustrates as of the present utility model and prevents that product from going out the structural representation of large-scale slide block structure one preferred embodiment of burr.

In order to achieve the above object, what the utility model provided prevents that product from going out the large-scale slide block structure of burr, large whole of shaped article 10, and this structure comprises:

Mother module core 100;

Male die core 101, with product 10 described in described mother module core 100 connecting shapings;

Large-scale slide block 102, is located between described male die core 101 and described mother module core 100, and large whole of product 10 described in moulding has between described large-scale slide block 102 and described male die core 101 to insert and break die joint.

Wherein, inserting between described large-scale slide block 102 and described male die core 101 broken die joint in the time of injection mo(u)lding, and the gap producing is less, and liquid plastic cement cannot be entered, for example, for being less than 0.03 millimeter.

Compared to prior art, utilize and of the present utility modelly prevent that product from going out the large-scale slide block structure of burr, insert broken die joint (described inserting between broken die joint and the direction of motion of described large-scale slide block 102 has less angle) owing to adopting between described large-scale slide block 102 and described male die core 101, even large-scale slide block 102 can be subject to larger briquetting pressure described in therefore in the time of injection moulding, described large-scale slide block 102 can be impacted to be retreated, the gap that slotting broken die joint between described large-scale slide block 102 and described male die core 101 produces is less, can not make plastic cement enter, therefore described product 10 can not form burr.

Wherein, between described large-scale slide block 102 and described male die core 101, can also there is vertical contact-making surface, the described vertical contact-making surface described broken die joint of inserting that continues, because the gap that the slotting broken die joint between described large-scale slide block 102 and described male die core 101 produces is less, therefore plastic cement can not enter, thereby due to this barrier effect of inserting broken die joint, plastic cement also can not enter described vertical contact-making surface.
