Abstract
The invention discloses a hot runner sprue bushing fixing structure of a die. The structure comprises a cooling bushing arranged on a cavity sprue, wherein the cooling bushing is provided with a transition cushion block; notches are formed in the transition cushion block; the top of each notch is flush with the surface of a cavity. A screw is arranged on the cavity, and the head of the screw is in compression connection with the notch. The height of the top surface of the head of the screw is lower than that of the surface of the cavity. The number of the notches is two or more than two, and the notches are uniformly formed in the top of the transition cushion block in the circumferential direction. A press block is arranged on the cavity; one end of the press block is in compression connection with the notches; the other end of the press block is connected with the cavity; the top surface of the press block is flush with the surface of the top of the cavity and the surface of the top of the transition cushion block. At least two waterproof rings are arranged on the cooling bushing. The hot runner sprue bushing fixing structure has the characteristics of simple and reasonable structure, high flexibility in operation and low manufacture cost.
Description
Technical field
The present invention relates to a kind of mould, particularly a kind of heat flow passage sprue lining fixed structure of mould.
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.
Summary of the invention
Object of the present invention aims to provide a kind of heat flow passage sprue lining fixed structure of simple and reasonable, mould that flexible operation, cost of manufacture are low, to overcome weak point of the prior art.
The heat flow passage sprue lining fixed structure of a kind of mould designed by this object, 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 present invention 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 present invention processes simply, and die can direct numerical control lathe be processed, and transition cushion block can by milling machine or grinding machine processing.
The present invention 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 present invention has simple and reasonable, flexible operation and the low feature of cost of manufacture.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
See Fig. 2-Fig. 5, the heat flow passage sprue lining fixed structure of this mould, comprises the cooling bushing 4 be arranged on die 5 cast gate, and this cooling bushing 4 is provided with transition cushion block 3, 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 invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
