Abstract
The utility model relates to an injection molding machine hopper. The utility model is characterized in that the traditional integrative hopper is changed to use cast iron to make the hopper, the inner part of the hopper is additionally provided with an inner liner sleeve barrel which is made of heat-resisting alloy steel, and the inner liner sleeve barrel can be disassembled and changed. The utility model has the advantages of heat-resisting alloy steel material saving, convenient disassembly and change, long service life and disassembly and change expense reduction. The injection molding machine hopper is suitable for the hoppers of various specifications.
Description
The present invention relates to injection molding machinery, particularly the improvement of injecting machine material tube structure.
The barrel of existing injection machine is made up of hopper, barrel, screw rod, barrel cap.Its shortcoming is at high temperature because the rotation of screw rod and material tube inner wall rubs, very easily produce wearing and tearing, the gap is increased, thereby increased injection time, influences production efficiency.In order to guarantee output, must often change barrel, and barrel is to adopt the 38CrMoAl heat-resisting alloy steel made in one piece, renewal cost is big.
The objective of the invention is to propose a kind of about the improved technical scheme of barrel structural form, barrel service life is prolonged, renewal cost reduces.
Content of the present invention is that whole barrel is improved to the barrel that has slip bushing, promptly cylinder iron make barrel, with heat-resisting alloy steel for example 38CrMoAl make disconnectable liner sleeve, the position of liner sleeve is at barrel extruded stock end, have between liner sleeve and the cast iron barrel to prevent the neck bush barrel dliameter to the locking key and the keyway that rotate, barrel discharging opening end prevents the axially movable gland of liner sleeve.
The invention has the advantages that when heat-treating nitrogenize hardness can be higher than the hardness of whole barrel, for example under similarity condition, liner sleeve hardness reaches HV1050, and therefore the highest HV850 that can only reach of whole barrel can increase the service life.Another advantage of the present invention is the reduction expense, has at first cylinder iron replaced most heat-resisting alloy steel, and Master Cost is reduced.The liner sleeve is only changed in secondly each replacing, and needn't change whole barrel, and renewal cost is reduced.
Embodiments of the invention as shown in drawings.Accompanying drawing is the shaft side figure of a kind of form of implementation of the present invention.Number in the figure: 1, hopper, 2, the cast iron barrel, 3, screw rod, 4, the liner sleeve, 5, the end gland, 6, locking key and keyway, 7, the barrel cap.
In conjunction with implementing accompanying drawing the present invention is further specified.The barrel 2 of traditional injecting machine material tube is the heat-resisting alloy steel integral manufacturing.The barrel outer wall is wound with heating wire, omits among the figure.Plastic grain is heated melting being promoted to advance by the screw rod rotation in the process of advancing after hopper 1 enters barrel 2, inject mould molding through tube cap 7.Improvement of the present invention is cylinder iron to make barrel 2, is equipped with the heat-resisting alloy steel liner sleeve 4 made of 38CrMoAl for example at barrel 2 inner chambers, on sleeve 4 outer walls locking key 6 is arranged, and corresponding locking key 6 has the stop keyway on cast iron barrel 2 inwalls.Between barrel 2 ends and the tube cap 7 gland 5 is arranged.Liner sleeve pipe 4 is packed into from barrel 2 ends.The liner sleeve pipe 4 of present embodiment is divided into two joint or three joints, and each saves sleeve can transposition.The benefit of this structure is when the wearing and tearing of end liners sleeve are scrapped, and can be put into non-end position continuation use by conversion one upper/lower positions.
The present invention is applicable to the injection machine of any specification.
Claims (2)
1, a kind of injecting machine material tube, constitute by hopper, barrel, screw rod, the assembling of barrel cap, it is characterized in that the liner sleeve is arranged in barrel, the position of liner sleeve is at barrel extruded stock end, have locking key to connect with keyway between liner sleeve and the barrel, there is liner sleeve gland barrel discharging opening end.
2, injecting machine material tube according to claim 1 is characterized in that described liner sleeve divides two joint or three joints, and each saves the liner sleeve can transposition.
