Description

There is the notebook computer casing injection mould of water dividing gap function in mould

Technical field

This utility model is related to notebook computer manufacturing technology field, has water dividing gap function in mould particularly to a kind of Notebook computer casing injection mould.

Background technology

There is some housings on notebook computer needs by way of injection being manufactured, after formed product Mouth of a river part always can produce some stub bars to be needed to go, so being often also performed to machining after Shooting Technique by mouth of a river stub bar Process leveling, such production efficiency is not ideal, constrains production-scale amplification.

Therefore, it is necessary to provide a kind of new injection mode structure to solve the above problems.

Utility model content

Main purpose of the present utility model is to provide a kind of notebook computer casing note with water dividing gap function in mould Mold.

This utility model is achieved through the following technical solutions above-mentioned purpose：A kind of notebook with water dividing gap function in mould Computer casing injection mould, including lower mould and upper mould, has the die cavity of generally planar extension between described upper mould and described lower mould, Described die cavity includes product chamber, runner and the mouth of a river being connected to described product intracavity side from described runner, sets in described upper mould There is the mouth of a river cutting knife just to described mouth of a river position, described lower mould is being provided with escape groove close to the position at the described mouth of a river.

Specifically, described upper mould includes sprue, the hot-fluid chamber connecting described sprue and extends from described hot-fluid chamber To some nozzles of described die cavity, described nozzle connects described runner.

Specifically, described mouth of a river cutting knife is wide at the top and narrow at the bottom, is embedded with the limited block of hollow in described upper mould, described limited block Hollow space is mated with the wide portion of described mouth of a river cutting knife.

Specifically, the knife edge of described mouth of a river cutting knife is in outer directly interior biassed fabric.

Specifically, described mouth of a river section is in the flat that height is less than described flow diameter.

Using technique scheme, the beneficial effect of technical solutions of the utility model is：

1st, injection, water dividing gap two procedures can just be completed in this utility model mould, blanking is exactly final product ontology, Work efficiency greatly improves；

2nd, limited block can play the effect limiting mouth of a river cutting knife direction, and collapses when the anti-waterstop port cutting knife of energy passes through upper mould Disconnected；

3rd, it is to face directly, so the section on product ontology can be made neat outside the knife edge of mouth of a river cutting knife；

4th, mouth of a river section is little, the mouth of a river molded body low intensity producing, and can more easily be cut off, and so that finished section is done Crisp neat.

Specific embodiment

With reference to specific embodiment, this utility model is described in further detail.

As shown in Figure 1 to Figure 2, a kind of notebook computer casing injection mould of the present utility model, including lower mould 1 and upper mould 2, There is between upper mould 1 and lower mould 1 die cavity 11 of generally planar extension, upper mould 2 includes sprue 21, the heat of connection sprue 21 Stream chamber 22 and 4 nozzles 23 extending to die cavity 11 from hot-fluid chamber 22, die cavity 11 includes the product chamber 110 of shaped as frame, connection spray The runner 111 of mouth 23 and the mouth of a river 112 being connected to product chamber 110 inner side from runner 111.After plastic material melting, will be from Sprue 21 flows into hot-fluid chamber 22, because the diffusional resistance in hot-fluid chamber 22 is little, melt plastic cement is easy to be diffused into whole heat Stream chamber 22, subsequently into each nozzle 23.Because nozzle 23 end caliber is very thin, flow resistance ratio is larger, so melts Plastic cement can enter air stream enter runner 111 in the similar time after being fully diffused into hot-fluid chamber 22, and then melt plastic cement passes through the mouth of a river 112 again Enter product chamber 110, fill up die cavity 11 and form injection molding body 3.After cooling, shaped article body 30 in product chamber 110, the mouth of a river 112 Interior molding mouth of a river molded body 33, the runner molded body 32 of molding long and thin in runner 111, only product ontology 30 is useful part, Then recycling after the remainder excision of injection molding body 3.Because runner molded body 32 is the mouth of a river molded body 33 through level It is connected on the inner edge of product ontology 30, rather than be connected to from face on product ontology 30, so will not be in face during cut-out On leave apparent stub bar, it is to avoid processed using complicated machining procedure.The mode cut off is taken to remove excess portion Point, process fast effect good.

As shown in figure 1, each nozzle 23 extends runner 111 toward 1 or 2 direction, the runner 111 in each direction is provided with 1 or 2 mouth of a river 112 being connected to product chamber 110.The dense degree at the mouth of a river 112 is relevant with the structure weighting of product ontology 3, energy Enough make more preferable each position that must be diffused into product chamber 110 of melt plastic cement, save injection time.

As shown in figure 3, the mouth of a river 112 section is in the flat that height is less than runner 111 diameter.The mouth of a river 112 section is little, produces Raw mouth of a river molded body 33 low intensity, can more easily be cut off, make finished section simply neat.

As shown in figure 3, being provided with the mouth of a river cutting knife 4 just to the mouth of a river 112 position in upper mould 2, lower mould 1 is close to 112, the mouth of a river Install escape groove 12.After the plastic material hardening in die cavity 11, mouth of a river cutting knife 4 is descending to be penetrated in escape groove 12, now The mouth of a river 112 is just completely severed with product ontology 30, just can complete injection, water dividing gap two procedures, blanking is just in this original mold Final product ontology 30, can directly censorship, work efficiency greatly improves.

As shown in Fig. 2 mouth of a river cutting knife 4 is wide at the top and narrow at the bottom, it is embedded with the limited block 5 of hollow, limited block 5 hollow bulb in upper mould 2 Divide and mate with the wide portion of mouth of a river cutting knife 4.Limited block 5 can play the effect limiting mouth of a river cutting knife 4 direction, and can cut anti-waterstop port Knife 4 breaks when passing through upper mould 2.

As shown in figure 3, the knife edge of mouth of a river cutting knife 4 is in outer directly interior biassed fabric.Outside is for facing directly, so product ontology 30 can be made On section neat.

Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art, On the premise of creating design without departing from this utility model, some deformation can also be made and improve, these broadly fall into this practicality New protection domain.
