Abstract
The utility model discloses a concave-convex type polyurethane foam forming device. The concave-convex type polyurethane foam forming device comprises a mold (1) and is characterized by also comprising a pressing plate (2), wherein the pressing plate (2) is provided with a sliding groove (8) and a sliding rod (9) arranged in the sliding groove (8); and the top end of the sliding rod (9) is provided with a downward boss (10) matched with an upward boss (7) for use. The concave-convex type polyurethane foam forming device disclosed by the utility model has the advantages that full forming without defects is ensured and the suitability for industrial large-batch production is achieved.
Description
Technical field
The utility model relates to a kind of concave-convex type polyurethane foaming and molding device, particularly a kind of full shaped device of concave-convex type polyurethane foam product moulding that guarantees.
Background technology
Development along with modern industry, because of the uniformity of the portability of polyurethane material, low heat conductivity, abscess and the feature such as compressive strength is large, its foaming product are applied to a plurality of fields of various industries, not only reduced cost but also can meet and adapt to different user demands, at present, glass fibre thermal insulation material, timber, traditional rubber etc. have been substituted in a large number.
But, in foaming process, if upper die and lower die do not press tightly, can cause the moulding of concave-convex type polyurethane foam to expand insufficient, cause forming defect, the problem such as moulding is not full, thus affect quality, outward appearance and the result of use of product.
Utility model content
Technical problem to be solved in the utility model is to provide the moulding of a kind of assurance concave-convex type polyurethane foam product full, without the shaped device of forming defect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of concave-convex type polyurethane foaming and molding device, comprise: mould, it is characterized in that: also comprise pressing plate, described mould comprises that inside is provided with the upper die and lower die of projection and groove, described patrix center is provided with elastic force bar, described elastic force masthead end is provided with stressed plate, described stressed plate periphery is provided with and raises up, described pressing plate center is provided with for the through hole through described elastic force bar, on described pressing plate, be provided with chute and be arranged on the slide bar in described chute, described top end of sliding rod be provided with described raise up be used in combination to lower convexity.
The number of described chute and slide bar is two, and linearly type is distributed in the two ends of described through hole.
The area of described pressing plate is greater than the area of described patrix.
The shape of described pressing plate and stressed plate is circular or square or rhombus, and the profile of described mould is square.
A concave-convex type polyurethane foam forming method, is characterized in that: comprise following operating procedure:
Step 1: charging, in mould, inject polyurethane;
Step 2: connect pressing plate and patrix, overlap joint raises up and to lower convexity, now slide bar at an angle to the horizontal direction, the angle ranging from 10～50 °;
Step 3: pressing mold, when polyurethane foam moulding, by the stressed plate to patrix, be continuously applied external pressure, until slide bar is the level of state, force polyurethane under liquid state, fully to expand into each corner in mold, obtain that concave-convex type polyurethane foam product and structure are full, moulding is abundant;
Step 4: form removal, discharge external pressure, elastic force bar moves upward, and mobile slide bar makes to raise up with separated to lower convexity, takes out concave-convex type polyurethane foam product.
A kind of concave-convex type polyurethane foaming and molding device that the utility model provides, the setting of pressing plate makes patrix stressed evenly, and then make product stressed evenly, to upper process with determined the degree of each pressing mold to being used in conjunction with of lower process, guarantee that the stressed degree of pressing mold of every batch products is identical, product density is identical, be applicable to industrialized mass, formed product is full, zero defect, and differences between batches are little, be applicable to applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, a kind of concave-convex type polyurethane foaming and molding device, comprise: mould 1, it is characterized in that: also comprise pressing plate 2, described mould 1 comprises that inside is provided with patrix 3 and the counterdie 4 of projection and groove, described patrix 3 centers are provided with elastic force bar 5, described elastic force bar 5 tops are provided with stressed plate 6, described stressed plate 6 peripheries are provided with and raise up 7, described pressing plate 2 centers are provided with for the through hole through described elastic force bar 5, on described pressing plate 2, be provided with chute 8 and be arranged on the slide bar 9 in described chute 8, described slide bar 9 tops be provided with described raise up 7 be used in combination to lower convexity 10.
The number of described chute 8 and slide bar 9 is two, and linearly type is distributed in the two ends of described through hole.
The area of described pressing plate 2 is greater than the area of described patrix 3.
The shape of described pressing plate 2 and stressed plate 6 is circular or square or rhombus, and the profile of described mould 1 is square.
A concave-convex type polyurethane foam forming method, is characterized in that: comprise following operating procedure:
Step 1: charging, in mould 1, inject polyurethane;
Step 2: connect pressing plate 2 and patrix 3, overlap joint raises up 7 and to lower convexity 10, and now slide bar 9 at an angle to the horizontal direction, the angle ranging from 10～50 °;
Step 3: pressing mold, when polyurethane foam moulding, by the stressed plate 6 to patrix 3, be continuously applied external pressure, until slide bar 9 is the level of state, force polyurethane under liquid state, fully to expand into each corner in mould 1 chamber, obtain that concave-convex type polyurethane foam product and structure are full, moulding is abundant;
Step 4: form removal, discharge external pressure, elastic force bar 5 moves upward, and mobile slide bar 9 makes to raise up 7 with separated to lower convexity 10, takes out concave-convex type polyurethane foam product.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
