Abstract
The utility model relates to a granulation pattern plate for producing plastic granules. The utility model is characterized in that the utility model is mainly composed of a connection body, a polymer mold cavity body and a core body, a bolt fastening hole, a thermal medium door, a thermocouple hole and a hoisting assembly hole can be respectively processed on the connection body, the bolt fastening hole is processed out on the core body, a polymer channel is processed out in the polymer mold cavity body, particularly a thermal medium channel is processed out by directly using a drilling method, and a hard alloy ring can be directly drilled and be inlaid between the upper part of the mold cavity body and an extrusion hole of polymer. The leakage of pattern plates caused by welding defects can be overcome, and the service life of pattern plates can be enhance d.
Description
The utility model relates to a kind of pelletizing template of making plastic grain.
At present, existing plastic pelletizing template all is by an integrated steel mold base, processes hot media channel, material duct, bolting hole and is formed the granulation band and constituted by the carbide alloy composite bed through different technical process.Wherein hot media channel designs in order to prevent polymer from solidifying in die cavity.Because the formwork structure difference, also each is variant for the processing technology of hot media channel.Disclosed in the Chinese patent 91222685.4 is " shell " formula heating arrangement, and disclosed in the Chinese patent 87215615.9 is " slot type " heating arrangement.Realize above-mentioned two kinds of structures, all adopt method for milling, process the hot media channel groove earlier, groove is sealed by welding method with steel plate then.The welding space of this structure is very narrow, and striking difficulty in weld seam bottom easily produces the bad result of not weld penetration during welding, and weld bond often crack just occurs through processing or after using, and causes template to leak, and reduces template service life.
The purpose of this utility model is the plastic pelletizing template of a kind of architecture advances of design, changes the processing technology of hot media channel, avoids because the defective that welding produces is leaked template, improves template service life.
Solution of the present utility model is, template is decomposed into connected body, and three parts of polymer-type cavity and core body process the bolting hole more respectively on connected body, and thermal medium is imported and exported, thermocouple hole, hole for hoist; On core body, process the bolting hole; In the polymer-type cavity, process polymer passage,, process the hot media channel hole, and the tungsten carbide button's ring of directly holing on the polymer-type cavity and between polymer-extruded hole carries out soldering, formation granulation band with direct drilling method.After the above-mentioned three part completion of processing, carry out assembly welding and constitute an integral mold plate.
The utility model compared to the prior art, its advantage is that template is made of connected body, polymer-type cavity and core body three parts.Can process separately each parts like this, simplify the past and can change first milling grooving in the past directly with the processing of drilling method loaded down with trivial details technology, the especially hot media channel that the monoblock template adds man-hour, after add the technology that steel plate carries out soldering and sealing.Thoroughly overcome because weld defect causes template to leak, thus the service life of having improved template.
Being described in detail below in conjunction with accompanying drawing, also is embodiment of the present utility model.
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is the cross section view of A-A among Fig. 1;
Fig. 3 is the cross section view of E-E among Fig. 2.
The plastic pelletizing template of being showed in the above-mentioned accompanying drawing, by connected body (2), polymer-type cavity (4), core body (6) three parts become a monoblock die body (1) through processing back assembly welding.A concave surface (8) is arranged on the same circumference of connected body (2), be evenly equipped with 16 bolt fastening hole (10) above, have a pair of symmetrical thermal medium to import and export passage (3) on the side wall surface of connected body (2), communicate with outer groove (11); Hot media channel hole (5) that directly gets out and two inclined holes (7), (9) that communicate with it are arranged in polymer-type cavity (4), inclined hole (7), (9) communicate with outer, inner groove (11), (13) respectively, constitute a hot switching path, guarantee that polymer does not solidify in extrusion.Also have a polymer-extruded groove (17) in the polymer-type cavity (4), it communicates with polymer-extruded hole (19), and on the polymer-type cavity and between polymer-extruded hole, directly boring is inlaid with carbide ring (21), constitutes the granulation band; In core body (6) that polymer-type cavity (4) links to each other, and be positioned at and be evenly equipped with 4 bolting holes (15) on the same circumference.Under the promotion of polymer at extruder of fusion, the cutter that is also rotated at a high speed by polymer-extruded hole (19) by groove (17) cuts into grain products.
Claims (3)
1, a kind of plastic pelletizing template, its formation comprises thermal medium import and export passage (3), hot media channel hole (5) and two inclined holes (7), (9) that communicate with it, inside and outside annular groove (13), (11), bolt fastening hole (10), (15), polymer-extruded groove (17), polymer-extruded hole (19), carbide ring (21), die body (1), it is characterized in that: die body (1) is by connected body (2), and polymer-type cavity (4) and core body (6) three parts interconnect successively and constitute.
2, according to the described plastic pelletizing template of claim 1, it is characterized in that: hot media channel hole (5) that direct drilling goes out and inclined hole (7), (9) that communicate with it are arranged on polymer-type cavity (4).
