Abstract
The utility model belongs to laptop accessories manufacturing technical field, it is related to a kind of notebook inner member compression mod, including the male model with the first die joint and the first cavity surface and the master mold with the second die joint and the second cavity surface, first cavity surface and second cavity surface cooperatively form type chamber, first die joint is equipped with the first husky hole and overflows slot, second die joint is equipped with the second husky hole and overflows slot, and the described first husky hole spilling slot, which overflows slot folder with the described second husky hole, forces to form the step-like overflow runner for connecting the type chamber.The overflow flow passage structure of the utility model increases molten metal by pressure, and molten metal is promoted to flow to the position of the intracavitary underfill of type, and avoiding die-cast product generation after molding from melting, flow rate of metal is uneven, and generation circle is husky, the undesirable conditions such as flow cracks phenomenon.
Description
Technical field
The utility model relates to laptop manufacturing technology field, in particular to a kind of notebook inner member compression mod.
Background technique
Having in laptop part some is metalwork by die cast, since laptop shape is flat,
So metalwork is also generally planar to sprawl structure.In general press casting procedure, molten metal enters in the middle part of mold, then past
It extends out and is scattered to entire type chamber, however it is uneven to be likely to occur molten metal flow velocity in practical press casting procedure, it is husky to generate circle, flows trace
Mark phenomenon, this will lead to shaped article local cavity, has husky the problems such as steeping, and generation is scrapped.
The utility model is to provide for the new die casting mold structure of one kind just to solve the above problems.
Utility model content
The main purpose of the utility model is to provide a kind of notebook inner member compression mods, can be avoided laptop
There is circle sand in part, and flow cracks etc. are bad.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of notebook inner member compression mod, including tool
There are the male model of the first die joint and the first cavity surface and the master mold with the second die joint and the second cavity surface, first type
Cavity surface and second cavity surface cooperatively form type chamber, and first die joint is equipped with the first husky hole and overflows slot, and described second
Die joint is equipped with the second sand hole and overflows slot, and the described first husky hole spilling slot is forced to be formed and be connect with the described second husky hole spilling slot folder
The step-like overflow runner of the type chamber.
Specifically, the overflow runner is gradually reduced by area toward male model outside.
Specifically, first die joint is equipped with the inlet channel for being connected to first cavity surface.
Further, the inlet channel is erietiform, and is connected to first cavity surface by several diversion channels.
By adopting the above technical scheme, the beneficial effect of technical solutions of the utility model is:
The overflow flow passage structure of the utility model increases molten metal by pressure, promotes molten metal to flow to type intracavitary
The position of underfill, avoiding die-cast product generation after molding from melting, flow rate of metal is uneven, and generation circle is husky, flow cracks phenomenon etc.
Undesirable condition.
Detailed description of the invention
Fig. 1 is the perspective view of embodiment male model；
Fig. 2 is the perspective view of embodiment master mold；
Fig. 3 is the cross-sectional view of overflow runner position.
Digital representation in figure:
1- male model, the first die joint of 11-, 111- first overflow slot, 112- inlet channel, 113- diversion channel in husky hole；12- first
Cavity surface,
2- master mold, the second die joint of 21-, 211- second overflow slot, the second cavity surface of 22- in husky hole；
101- type chamber, 102- overflow runner.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
Embodiment:
As shown in Figure 1 to Figure 3, a kind of notebook inner member compression mod of the utility model, including there is the first die joint
11 and first cavity surface 12 male model 1 and master mold 2 with the second die joint 21 and the second cavity surface 22, the first cavity surface 12
Type chamber 101 is cooperatively formed with the second cavity surface 22, the first die joint 11 is equipped with the first husky hole and overflows slot 111, the second die joint
21, which are equipped with the second sand hole, overflows slot 211, and slot 111 is overflowed in the first husky hole and the second husky hole spilling folder of slot 211 forces to form connecting-type
The step-like overflow runner 102 of chamber 101.First husky hole spilling slot 111 and the second husky hole spilling slot 211 are processed more convenient.
Step-like 102 structure of overflow runner of the utility model significantly increases molten metal by pressure, promotes motlten metal stream
The position of other underfills into type chamber 101, avoiding die-cast product generation after molding from melting, flow rate of metal is uneven, and generation is enclosed
Sand, the undesirable conditions such as flow cracks phenomenon.
As shown in Fig. 2, overflow runner 102 by area toward being gradually reduced on the outside of male model 1.It is got over by the area of runner
Small, bigger to the resistance of fluid, this can enable the molten metal being discharged from overflow runner 102 by increasing resistance, promote
Fluid internal pressure evenly distributes molten metal, improves mold effect.
As shown in Figure 1, the first die joint 11 is equipped with the inlet channel 112 of the first cavity surface 12 of connection, inlet channel 112 is sheep
It is angular, and the first cavity surface 12 is connected to by several diversion channels 113.Inlet channel 112 makes the molten metal elder generation side of injection type chamber 101
To sprawling, type chamber 101 is then entered by diversion channel 113 again, such molten metal diffusion is relatively uniform.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
