Abstract
The utility model relates to a foaming mould capable of forming a multi-density product at one step, which comprises a male mould side, a female mould side and a mould cavity formed by a mould core on the male mould side and an inner cavity on the female mould side. The foaming mould is characterized in that one or more partition boards capable of extending into the mould cavity to partition the mould cavity is arranged on the female mould side, wherein the tail ends of the partition boards are connected with an air cylinder. The utility model has the advantages that the mould cavity is partitioned by the partition boards into two or more inner cavities; different amounts of foaming materials are respectively filled into the inner cavities; and foaming products with different densities at various parts can be formed at one step through the air cylinder after the partition boards are pulled out.
Description
Technical field
But the utility model relates to a kind of foaming mould of one-shot forming multi-density product, comprises male model side, master mold side, and cooperates the die cavity that constitutes by the core of male model side with the inner chamber of master mold side.
Background technology
Foamed products in the market is mainly single density product, when the local characteristics to product has requirement, need change the density of product local location according to the requirement of characteristic.The method of domestic present use is to adopt bonding or gradation foaming to make.Make very inconveniently, efficient is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of foaming mould, but one-shot forming has the foamed products of multiple density, the make efficiency height.
For solving the problems of the technologies described above, the technical solution of the utility model is: but a kind of foaming mould of one-shot forming multi-density product, comprise male model side, master mold side, and cooperate the die cavity that constitutes with the inner chamber of master mold side by the core of male model side, it is characterized in that: described master mold side is provided with one or more demarcation strips that in the die cavity die cavity separated that stretch into, and the end of described demarcation strip is connected with cylinder.
Further, have on the male model side directly over the described demarcation strip and can hold the imitative type inner chamber that demarcation strip stretches into, be provided with sealing plate in this imitative type inner chamber, the end of described sealing plate is connected with the compression spring.
Advantage of the present utility model is: demarcation strip is divided into two or more inner chambers with die cavity, can charge into the foaming raw material of different amounts at these inner chambers respectively, can one-shot forming make the foamed products that each position has different densities after by cylinder demarcation strip being taken out.
During foaming, demarcation strip stretches into the imitative type inner chamber of male model side from the master mold side, guarantees that demarcation strip can prevent that the expanded material of demarcation strip one side from scurrying into opposite side thoroughly with the die cavity separation.
Description of drawings
But accompanying drawing is the foaming mould structural representation of the utility model one-shot forming multi-density product.
The specific embodiment
As shown in drawings, comprise male model side 1, master mold side 2, demarcation strip 3, feed pipe 4, cylinder 5, sealing plate 6, compression spring 7.
The core of above-mentioned male model side 1 cooperates the die cavity that forms this foaming mould with the inner chamber of master mold side 2, on master mold side 2, be provided with one or more demarcation strips 3 that stretch in the die cavity, described demarcation strip 3 can be separated into die cavity several compartments, and the bottom of described each compartment all is connected with feed pipe 4.The end of demarcation strip is connected with cylinder 5, during foaming, under the promotion of cylinder 5, demarcation strip 3 stretches into and is divided into several compartments in the die cavity, and in compartment, charge into the expanded material that can make different densities respectively by each feed pipe 4, after charging into expanded material, take out demarcation strip 3 by cylinder 5 again, can one-shot forming make the foamed products that the part has different densities.
In order to guarantee that demarcation strip 3 can separate die cavity fully, prevent that the expanded material in the different compartments from phenomenon taking place to scurry mutually, male model side 1 directly over demarcation strip 3 has can hold the imitative type inner chamber that demarcation strip 3 stretches into, and is provided with sealing plate 6 in the inner chamber, and the end of sealing plate 6 is connected with compression spring 7.When cylinder 5 upwards promoted demarcation strip 3, demarcation strip 3 entered imitative type inner chamber and props up sealing plate 6, and the compression spring 7 of sealing plate 6 ends is compressed simultaneously.Imitative type inner chamber is stretched at demarcation strip 3 tops, and cooperates with sealing plate 6, can effectively guarantee the independent sealed of each compartment.After expanded material charged into, cylinder retreated, and pulling demarcation strip 3 is extracted out, and compression spring 7 returns are put sealing plate 6 pop into position, constitute a die cavity of finishing, and carry out the foaming of product.
Claims (2)
1. but the foaming mould of an one-shot forming multi-density product, comprise male model side, master mold side, and cooperate the die cavity that constitutes with the inner chamber of master mold side by the core of male model side, it is characterized in that: described master mold side is provided with one or more demarcation strips that in the die cavity die cavity separated that stretch into, and the end of described demarcation strip is connected with cylinder.
2. but the foaming mould of one-shot forming multi-density product according to claim 1, it is characterized in that: on the male model side directly over the described demarcation strip, have and to hold the imitative type inner chamber that demarcation strip stretches into, should be provided with sealing plate in the imitative type inner chamber, the end of described sealing plate is connected with the compression spring.
