Description
Technical field
The utility model relates to a kind of heat flow passage sprue lining fixed structure.
Background technology
When the structure that mould is hot runner mould, existing heat flow passage sprue, see shown in accompanying drawing 1, in order to the heat of improved cooling gate bush place mould, mould can add cooling bushing 4 usually.This cooling bushing 4 is standard component, can produce in batches.During use, for die or the core rod of different-thickness, need to set up transition cushion block 3 between cooling bushing 4 and die or core rod.Under normal circumstances, cooling bushing 4 is provided with water proof ring 1.When keeping in repair and safeguarding, the frequent dismounting mould of meeting, can cause water proof ring 1 to damage or lose, cause mould to occur drainage, burn out hot flow path in disassembly process.This situation, makes user quite dissatisfied.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, heat flow passage sprue lining fixed structure that flexible operation, cost of manufacture are low, to overcome weak point of the prior art.
By a kind of heat flow passage sprue lining fixed structure that this object designs, comprise the cooling bushing be arranged on die cast gate, its architectural feature is that cooling bushing is provided with transition cushion block, and this transition cushion block is provided with breach, and the top of this breach is concordant with the surface of die.
Further, described die is provided with screw, the head of this screw is crimped on breach.
Further, the head top surface height of described screw is lower than the apparent height of die.
Further, described breach is more than two, and breach circumference is distributed on the top of transition cushion block.
Further, described die is provided with briquetting, one end of this briquetting is crimped on breach, and the other end of briquetting connects with die, and the end face of briquetting is concordant with the top surface of the top surface of die, transition cushion block.
Further, described cooling bushing is provided with more than one water proof ring.
The utility model is provided with transition cushion block at cooling bushing, and this transition cushion block is provided with breach, and the top of this breach is concordant with the surface of die, and die is provided with screw, and the head of this screw is crimped on breach; Transition cushion block and die lock together by screw, thus avoid cooling bushing to depart from, and play fixing effect, and simplify operation.In addition, this breach and screw additionally do not take die space, can avoid the interference cooling fortune aquaporin and other parts to greatest extent, reduce cost of manufacture.
The utility model processing is simple, and die can direct numerical control lathe be processed, and transition cushion block can by milling machine or grinding machine processing.
The utility model is provided with screw on die, and the head of this screw is crimped on breach, by mounting or dismounting screw, can realize the replacing of transition cushion block, operates suitable easy.
In sum, the utility model has simple and reasonable, flexible operation and the low feature of cost of manufacture.

See Fig. 2-Fig. 5, this heat flow passage sprue lining fixed structure, comprises the cooling bushing 4 be arranged on die 5 cast gate, and this cooling bushing 4 is provided with transition cushion block 3, and this transition cushion block 3 is provided with breach 3.1, and the top of this breach 3.1 is concordant with the surface of die 5.
In the present embodiment, described die 5 is provided with screw 6, the head of this screw 6 is crimped on breach 3.1.
The head top surface height of screw 6 is lower than the apparent height of die 5.
Breach 3.1 is more than two, and breach 3.1 circumference is distributed on the top of transition cushion block 3.
Described die 5 is provided with briquetting, and one end of this briquetting is crimped on breach 3.1, and the other end of briquetting connects with die 5, and the end face of briquetting is concordant with the top surface of the top surface of die 5, transition cushion block 3.
Cooling bushing 4 is provided with more than one water proof ring 1.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
