Description

A kind of breechblock moulding injection mold

Technical field

This utility model belongs to plastic fittings Precision Machining field, especially a kind of breechblock moulding injection mold.

Background technology

The requirement on machining accuracy of auto parts and components is very high, especially for playing sealing function and sealing member in irregular shape, multiple contact surfaces play the effect of sealing surface, especially high for requirement on machining accuracy, after generally requiring injection moulding, artificial secondary operations can be only achieved requirement again, inefficient and, die sinking stripping result is bad, even can disfiguring workpiece；Independent processing efficiency is low, and causes the wastage of material in running channel more, and existing common processing mold is difficult to reach the quality of production requirement and efficiency.

Utility model content

The purpose of this utility model is in that to overcome the deficiencies in the prior art part, it is provided that a kind of simple in construction, be easy to processing, breechblock moulding injection mold reasonable in design, easy to use.

This utility model solves it and technical problem is that and take techniques below scheme to realize:

A kind of breechblock moulding injection mold, by relatively fastening upper mould and counterdie, injection moulding die cavity is formed in the upper mould fastening end face with counterdie, the workpiece of correspondence is formed after injecting liquid material cooling and shaping, it is characterized in that: upper mould is rectangular cubic structure, be shaped with eight running channels connected with counterdie uniformly at intervals in the upper surface of upper mould, on the correspondence car of each running channel lower end, mould lower surface is all shaped with model groove, and four running channel center all symmetries of both sides are shaped with a unhurried current gulf；Be shaped with injection molding channel in the upper surface of upper mould, injection molding channel outfan is respectively symmetrically the unhurried current gulf being diverted to two middle side parts, again through injection molding channel by the gulf symmetrical flow division that flows slowly to four adjacent running channels；The embedded counterdie being fixed with two pieces of lateral symmetry settings in the middle part of lower bolster, is molded with eight type grooves arranged uniformly at intervals under every piece, these eight type grooves form complete injection moulding die cavity with upper model groove opposing seal Guan Bi.

And, injection molding channel is arc-shaped structure and is easy to water conservancy diversion, and unhurried current gulf is a circular groove structure.

And, the cope match-plate pattern end face outside running channel is all shaped with the spilling runner of a connection, overflow be shaped with between runner and runner shunting every.

Advantage of the present utility model and having the benefit effect that

1, this mould adopts multiple die cavitys to synchronize injection moulding, the multiple product of one-shot forming, and working (machining) efficiency is high, raw material uniform divided flows is in surrounding die cavity, and the raw material of runner internal loss economizes in raw materials less, raising efficiency, and die cavity periphery be symmetrically distributed with temperature control runner, good cooling results.

2, in this structure, mould is high with counterdie fitness, and injection moulding die cavity is shaped with locking mechanism and the guide frame of correspondence, and positioning precision is high, degree of stability is good, and structure is ingenious, is effectively ensured workpiece to be processed position precision in mold cavity, thus ensureing the uniformity of injection moulding, it is ensured that crudy.

3, simple in construction of the present utility model, reasonable in design, working (machining) efficiency is high, simple in construction long service life, the good stability of structure, machining accuracy is high, and is easy to the demoulding, promotes working (machining) efficiency, applied widely, is effectively ensured crudy.

Accompanying drawing labelling: mould on 1,2 injection molding channels, 3 overflow runners, and 4 shuntings are every, 5 running channels, 7 bolts hole, 8 counterdies, 9 type grooves, 10 cope match-plate patterns.

Detailed description of the invention

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following example are illustrative, are not determinate, it is impossible to limit protection domain of the present utility model with this.

A kind of breechblock moulding injection mold, by relatively fastening upper mould and counterdie, forms injection moulding die cavity in the upper mould fastening end face with counterdie, forms the workpiece of correspondence after injecting liquid material cooling and shaping,

The concrete structure of upper mould is referring to shown in accompanying drawing 1, and the embedded upper mould 1 being fixed with two pieces of lateral symmetry settings in the middle part of cope match-plate pattern 10, every piece of upper equal interval, mould edge is shaped with eight bolts hole 7 for installing fixing bolt；Upper mould is rectangular cubic structure, is shaped with eight running channels connected with counterdie 5 uniformly at intervals in the upper surface of upper mould, and on the correspondence car of each running channel lower end, mould lower surface is all shaped with model groove, and four running channel center all symmetries of both sides are shaped with a unhurried current gulf 6；Be shaped with injection molding channel 2 in the upper surface of upper mould, the injection molding channel input port end connection injection moulding head in the middle part of upper mould, injection molding channel outfan is respectively symmetrically the unhurried current gulf being diverted to two middle side parts, again through injection molding channel by the gulf symmetrical flow division that flows slowly to four adjacent running channels 5.

The injection molding channel of the present embodiment is arc-shaped structure and is easy to water conservancy diversion, and unhurried current gulf is a circular groove structure, it is simple to buffering and uniform divided flows.

In order to control injection rate, the cope match-plate pattern end face outside each running channel is all shaped with the spilling runner 3 of a connection, is shaped with shunting every 4 overflowing between runner and runner, tap every the spill-out of Altitude control injection molding channel.

Longitudinal side wall at upper mould be shaped with uniformly at intervals five longitudinally through temperature control runner, this temperature control uniform flow passage is distributed between running channel, and the coolant in adjacent temperature control runner is in opposite direction.

Counterdie concrete structure is referring to shown in accompanying drawing 2, the embedded counterdie 8 being fixed with two pieces of lateral symmetry settings in the middle part of lower bolster, being molded with eight type grooves 9 arranged uniformly at intervals under every piece, these eight type grooves form complete injection moulding die cavity with upper model groove opposing seal Guan Bi；Longitudinal side wall at counterdie be shaped with uniformly at intervals five longitudinally through temperature control runner, this temperature control uniform flow passage is distributed between type groove, and the coolant in adjacent temperature control runner is in opposite direction.

Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope without departing from this utility model and claims, various replacements, to change and modifications be all possible, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
