Description
Technical field
The utility model is related to injection molding machines.
Background technology
In the prior art, the cope plate of vertical injection molding machine is integral, and two molds are installed on vertical injection molding machine, folding
When mould, the upper mold of two molds will move simultaneously, therefore injection molding machine function is restricted, and two molds can only produce similarly
Product cannot individually control the open mold of one set of die, cannot carry out the double-shot moulding product different with production, can not pacify
A secondary upper mold is filled, in the case that two pairs are with upper and lower mould, when a secondary mold is in injection molding, another pair lower die can complete the behaviour of pickup
Make.
In addition, when injection molding machine is molded, the material in hopper is usually solid-like, if the material under room temperature is directly defeated
Entering into barrel, material needs to absorb a large amount of heat in barrel, it is therefore desirable to the temperature in barrel is higher, and cannot
Ensure that the temperature of charge in barrel is uniform.In addition, since material is in molten condition in barrel, good fluidity is stopping noting
After modeling, although injection molding machine stops pressurization, the raw material in barrel still has overbottom pressure, if blocking feeding mouth not in time, material can be from type
The feed inlet of chamber flows out, and forms curtain coating, influences the quality of product.At present using needle-valve sealed material mouth there are two types of main Types, one
Kind it is that needle-valve is set in material mouth, needle-valve top is matched with discharge port, needle-valve tail end setting spring, when injection molding, utilizes raw material
Pressure makes needle-valve compressed spring and rear shifting, and raw material can be by nozzle, after the completion of injection molding at this time, and injection molding machine stops pressurization, and spring is multiple
Position pushes needle-valve to close feed inlet.The advantages of this device is simple in structure, the disadvantage is that injection pressure must sufficiently high ability gram
The active force for taking spring, to open nozzle, high pressure can be such that raw material further heats, and lead to the chemical changes such as degradation, this dress
It sets and is not particularly suitable for the raw material that silica gel etc. needs low temperature to be molded.Another kind is to drive needle-valve using external force, this just needs a set of
Relative complex mechanical structure, this mode involve great expense, and maintenance cost is high.
