Abstract
The utility model relates to a nozzle cutting device in a mold, including a nozzle mold insert and a thimble set; the nozzle mold insert corresponds to that front and back mold cavities are divided into upper and lower portions; a flow channel accommodating cavity is formed between upper and lower portions of the mold insert; an edge is disposed on the cavity side; the thimble set includes a product thimble, a nozzle cutting thimble and a flow channel thimble; lower ends of the product thimble, the nozzle cutting thimble and the flow channel thimble are arranged in a thimble plate; and the other ends are respectively arranged with respect to the product, the nozzle mold insert edge and the flow channel accommodating cavity; the thimble plate is provided with a cavity with respect to the flow channel thimble end and the flow channel thimble end is in sleeve joint in the cavity and moves up and down. The utility model realizes the nozzle cutting in the mold through arranging the nozzle mold insert, and the thimble set and the thimble plate which are in differential fit for the conventional mold so as to directly decrease the trouble of secondary processing for products after molding.
Description
[technical field]
The utility model relates to a kind of injection mold servicing unit, refers in particular to water dividing gap device in a kind of mould.
[background technology]
Plastic mould is usually directed to carry out the product of injection mo(u)lding the water dividing gap operation at last in injection moulding, and existing mold water dividing gap mode is divided into following several:
1, by the screw in injection molding machine feed back, nozzle retreated when product began to cool down, mould filling pipe end mold insert spring ejects, thereby realized in the mould water dividing gap automatically.Shortcoming: the ejecting action and must chew by the purt on the mould and cooperate the motion of hydraulic cutting presser nozzle to finish only suitable small mould of a. mouth of a river movable insert; B. mold insert spring easy deformation, mouth of a river tangent plane out-of-flatness.
2, the screw in injection molding machine feed back is in parallel with oil cylinder oil-feed signal, adopt cylinder secondary to eject, realize water dividing gap in the mould.Shortcoming: the oil cylinder area occupied is big, needs special injection machine, uses restricted.
3, the ejection system of injection machine itself has the function that ejects under the mold closing state, can freely eject in the arbitrary period before the die sinkings such as injection, pressurize, cooling.Shortcoming: need custom-designed injection machine, the price height, second-hand machine is transformed difficulty.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, and a kind of all kinds of moulds that are common to are provided, and structure is cut off the interior water dividing gap device of mould of simple and reliable process.
The purpose of this utility model is achieved in that water dividing gap device in a kind of mould, it also comprises mouth of a river mold insert and thimble group, described mouth of a river mold insert correspondence is that forward and backward die is divided into upper and lower two parts, is formed with the runner containing cavity between the mold insert upper and lower part, and cavity side is provided with the edge of a knife; Described thimble group is made up of product thimble, water dividing gap thimble and runner thimble, and the lower end of described product thimble, water dividing gap thimble and runner thimble is arranged in the ejector retainner plate, and other end corresponding product, the mouth of a river mold insert edge of a knife and runner containing cavity respectively is provided with; The corresponding runner thimble of described ejector retainner plate termination is provided with one and can supplies its up and down cavity socket;
In the said structure, described runner containing cavity wedgewise;
In the said structure, described wedge shape runner containing cavity is 0.5-1.5mm in water dividing gap thimble side housing depth;
In the said structure, described ejector retainner plate lumen height 3-5 millimeter;
In the said structure, the edge of a knife on the top of described mouth of a river mold insert becomes 20-60 degree angle with vertical plane.
The beneficial effects of the utility model are by thimble group and ejector retainner plate for common mold arrangement mouth of a river mold insert and differential cooperation, thereby can realize water dividing gap in the mould, have directly reduced the trouble of secondary operations after the formed product.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is a structural representation of the present utility model
[specific embodiment]
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.
Common mould includes pedestal 3, module 1, back module 2 before being provided with on the pedestal 3, die 11 and back die 21 before being respectively equipped with in preceding module 1 and the back module 2.The water dividing gap device can generally be arranged in the mould of said structure in the mould that the utility model relates to, and as shown in Figure 1, it comprises ejector retainner plate 4, mouth of a river mold insert 5 and the thimble group that is arranged in the mould.
Above-mentioned mouth of a river mold insert 5 is made up of upper and lower two parts, two parts correspondence is arranged in preceding die 11 and the back die 12, be formed with runner containing cavity 200 between the two, the side of runner containing cavity 200 need be designed to wedge, the width of wedge is generally 2-10mm according to product, tapered end is formed with the edge of a knife, and containing cavity 200 these parts are that the housing depth of product side (being water dividing gap thimble 8) is 0.5-1.5mm, and the mouth of a river mold insert 5 top edges of a knife and product be vertical to become 20-60 degree angle.
The thimble group then is made up of runner thimble 7, water dividing gap thimble 8 and product thimble 9, and thimble group one end is arranged in the ejector retainner plate 4, and other end corresponding product 100, mouth of a river mold insert 5 edges of a knife and runner containing cavity 200 respectively is provided with.The water dividing gap thimble 8 of thimble group and product thimble 9 are fixed in the ejector retainner plate 4, and corresponding runner thimble 7 is provided with cavity 401 in ejector retainner plate 4, cavity 401 high 3-5 millimeters, described runner thimble 7 termination point casings are connected on also can be along up and down in it in the cavity 401, thus when the preceding module 1 of mould during with back module 2 die sinkings, thereby runner thimble 7 that can be by the thimble group is realized water dividing gap in the mould in ejecting for differential secondary of 9 on water dividing gap thimble 8, product thimble.
It is to be noted; the utility model is not limited to above-mentioned embodiment; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description in based on technical solutions of the utility model all belong in the protection domain of the present utility model.
