Description
Technical field
The present invention relates to plastic tray injection mold, particularly relate to the cooling device of plastic tray injection mold steel pipe groove loose core.
Background technology
In the logistics progresses such as storage and transport, widely use pallet, and existing pallet is plastics forming mostly, plastic pallet is easy to manufacture, and speed is fast, pattern change is many, waste and old pallet can reclaim again, but the mechanical strength of plastic pallet is on the low side, so people are shaped with chamfer putting steel tube in plastic pallet, in chamfer putting steel tube, install steel pipe, object plays booster action.The injection mold manufacturing plastic pallet is generally by installing steel pipe groove loose core on prong slide block, when die sinking, prong slide block drives through oil cylinder, prong slide block drives steel pipe groove loose core to extract out simultaneously, mostly cooling water channel is not had in the steel pipe groove loose core of prior art, when the demoulding, steel pipe groove loose core does not often cool completely, therefore when deviating from, the easy plucking of chamfer putting steel tube, there is flaw, affect product quality, and existing chamfer putting steel tube is generally in the below of forklift prong, its shortcoming existed is mostly most of sectional area of prong is to shovel entry, wall is thin, after the peace of perforate herein steel pipe, steel pipe is less to the spacing on surface, when forklift mentions pallet and goods, due to Heavy Weight, pallet produces and breaks, service life is short.
Summary of the invention
The object of the invention is the shortcoming existed to overcome prior art, providing one to make steel pipe core_pulling demoulding smooth, improving chamfer putting steel tube intensity, ensure the cooling device of product quality and the plastic tray injection mold steel pipe groove loose core in service life.
The technical scheme of the cooling device of plastic tray injection mold steel pipe groove loose core of the present invention is: comprise core fixing plate, core fixing plate is installed periphery insert, the little insert of dish pin and the large insert of dish pin, at core fixing plate sidewall, slide block slot is installed, slide block slot is arranged prong slide block, prong slide block there is fork insert, it is characterized in that the described little insert of dish pin and the large insert of dish pin respectively have chamfer putting steel tube, in chamfer putting steel tube, steel pipe groove loose core is set, steel pipe groove loose core one is shaped with fixed block, fixed block and prong slide block fix, cooling water channel is had in described steel pipe groove loose core, cooling water channel has water inlet or delivery port, cooling water enters cooling water channel from water inlet, the cooling water of cooling water channel flows out from delivery port.
The invention discloses a kind of cooling device of plastic tray injection mold steel pipe groove loose core, respectively steel pipe groove loose core is had in the little insert of dish pin and the large insert of dish pin, the steel pipe groove loose core that in each chamfer putting steel tube, each two, installation left and right is symmetrical, wherein open cooling water channel and water inlet in a steel pipe groove loose core, cooling water channel and delivery port is opened in another root steel pipe groove loose core, so a cooling water channel only has water inlet or delivery port, when after plastic pallet injection mo(u)lding, cooling water flows into cooling water channel from water inlet, cooling water exports from the delivery port of the steel pipe groove loose core of another side again, thus steel pipe groove loose core can be cooled fast, ensure product quality.And chamfer putting steel tube being arranged on the dish placement of foot of pallet, chamfer putting steel tube periphery wall thickness, intensity is good, and the weight that can bear is large, improves service life and the lifting capacity of plastic pallet.
The cooling device of plastic tray injection mold steel pipe groove loose core of the present invention, have cooling water channel and lower cooling water channel in described steel pipe groove loose core, upper cooling water channel communicates with upper water inlet, and lower cooling water channel communicates with lower water inlet.Article two, cooling water channel, good cooling results.

Fig. 2 is the schematic perspective view of the cooling device of plastic tray injection mold steel pipe groove loose core;
Fig. 3 is the schematic cross-section of the cooling device of plastic tray injection mold steel pipe groove loose core.
Detailed description of the invention
The present invention relates to a kind of cooling device of plastic tray injection mold steel pipe groove loose core, as shown in Fig. 1-Fig. 3, comprise core fixing plate 1, core fixing plate is installed periphery insert 2, the little insert of dish pin 3 and the large insert 4 of dish pin, at core fixing plate sidewall, slide block slot 5 is installed, slide block slot is arranged prong slide block 6, prong slide block there is fork insert 7, it is characterized in that the described little insert of dish pin 4 and the large insert of dish pin respectively have chamfer putting steel tube 8, steel pipe groove loose core 9 is set in chamfer putting steel tube, steel pipe groove loose core one is shaped with fixed block 10, fixed block and prong slide block 6 fix, cooling water channel is had in described steel pipe groove loose core 9, cooling water channel has water inlet or delivery port, cooling water enters cooling water channel from water inlet, the cooling water of cooling water channel flows out from delivery port.Chamfer putting steel tube 8 is respectively had in the little insert of dish pin 3 and the large insert 4 of dish pin, the steel pipe groove loose core 9 that in each chamfer putting steel tube, each two, installation left and right is symmetrical, wherein open cooling water channel and water inlet in a steel pipe groove loose core, cooling water channel and delivery port is opened in another root steel pipe groove loose core, so a cooling water channel only has water inlet or delivery port, when after plastic pallet injection mo(u)lding, cooling water flows into cooling water channel from water inlet, cooling water exports from the delivery port of the steel pipe groove loose core of another side again, thus steel pipe groove loose core 9 can be cooled fast, ensure product quality.And chamfer putting steel tube 8 being arranged on the dish placement of foot of pallet, chamfer putting steel tube periphery wall thickness, intensity is good, and the weight that can bear is large, improves service life and the lifting capacity of plastic pallet.Have cooling water channel 11 and lower cooling water channel 12 in described steel pipe groove loose core 9, upper cooling water channel communicates with upper water inlet 13, and lower cooling water channel communicates with lower water inlet 14.Article two, cooling water channel, good cooling results.
