The ejection mechanism and a casting system are used on the sliding mechanism, so the ejection mechanism and the casting system can realize the harmonious operation with the sliding mechanism, the qualification rate of products is greatly improved, and in addition, the mold has a simple structure and is easy to implement.
Description
Technical field
The utility model relates to a kind of improved mould, but specifically is a kind of mould that is provided with the campaign-styled ejecting mechanism of lateral sliding, is applied to produce plastic parts, die casting field.
Background technology
In the prior art, produce by mould in the process of products such as plastic parts, die casting, tend to be applied to slide block structure, make formed product by being used of flow passage system, ejecting mechanism and slide block independently, but for fear of considering that the slide position is provided with, when designing mould, tend to miss the good glue point position of advancing, and can cause certain interference mutually during action between the three, influence production process.In being provided with the mould of slide block structure, prior art is to adopt some traditional to advance the glue mode, the glue-feeder of fishhook-type for example, design can not have too many variation but this mode has but caused mould, its tail end sectional area reduces also to cause the back pressure of formed product to rise quickly rapidly, and it advances the glue point and produced material bits when breaking, and these material bits can cause product bad or weigh mould wounded in following one-period production process, and these shortcomings have increased production cost virtually.
Technical purpose of the present utility model is flow passage system, ejecting mechanism are used in the mechanism of lateral sliding, ejecting mechanism can be ejected stub bar after die sinking smoothly, and be unlikely to be hindered by lateral sliding mechanism or damaged by relevant mechanism, make its non-interfering harmonious running, and select the suitable glue mode of advancing, overcome the defective of prior art.
The utility model content
In order to realize above-mentioned technical purpose, but the utility model discloses a kind of mould that is provided with the campaign-styled ejecting mechanism of lateral sliding, comprise master mold, male model, slide mechanism and ejecting mechanism, it is characterized in that:
Described ejecting mechanism comprises the stub bar thimble and upper plate, the lower roof plate of stub bar thimble is set that be provided with the side direction chute in the described upper plate, stub bar thimble bottom is located in the side direction chute; Described slide mechanism comprises slide block, and slide block is provided with runner, is provided with the centre hole that communicates with runner in the slide block, and centre hole is located at the below of runner, and stub bar thimble epimere is located in the described centre hole, and during liftout, the stub bar thimble is along centre hole direction knee-action.
Described flow field end is provided with slag well.
Be provided with the stalking Jiao Jiaokou that connects runner and die cavity in the described slide block.
As preferably, described stalking Jiao Jiaokou is made as the rectangle taper, and its section is rectangular.
The mold glue mouth is made as side when advancing glue glue mouth, and described side is advanced Jiao Jiaokou and is located in the master mold, and Jiao Kou is connected with runner on the slide block.Behind the matched moulds, in the vertical direction, the side in the master mold of top is advanced the end of Jiao Jiaokou and is coincided with runner front end on the slide block of below and is communicated with, and part of its coincidence connection is stress concentration point.
The epimere of stub bar thimble is fixed in the centre hole of slide block inside, and along with slide block mobile cooked lateral movement, compared with prior art stub bar thimble and the separate action of slide block, the interference when the utility model has been avoided motion between the two makes its cooperation more harmonious.When the stub bar thimble was in side direction chute one side, its distance to opposite side (being the stroke range of thimble in the side direction chute) must be not less than the stroke distances of slide block.Runner with advance the glue point and be located on the slide block, then be easier to the selection that the best is entered glue point position.When Jiao Kou is set to stalking glue glue mouth, its glue mouth must be designed and can when bearing horizontal drawing, just product can be disconnected, traditional shearing force disconnected change pulling capacity into and disconnect, but the anti-constriction value height of traditional glue-feeder, can't break with the side direction pulling capacity, therefore just need to advance glue point shape and do how much changes, the experimental result of advancing glue according to more multiple section configuration Jiao Kou draws, the anti-constriction value of the section of rectangle minimum, promptly the easiest being broken, so the shape of the preferred rectangle of Jiao Kou awl, and the long limit that makes rectangular cross section is as much as possible greater than the length of its minor face, the constriction impedance that thickness is little before then breaking is little, and thickness is easier to heat radiation for a short time.As the pectin mouth is that side is advanced Jiao Jiaokou, just Jiao Kou must have been stayed in the master mold, can utilize runner to be broken runner and glue-feeder with the stress concentration point (promptly advance glue point and overlap the part that is communicated with runner) between the glue mouth with the pulling capacity of slide block.
Beneficial effect: the utility model has improved the flow equilibrium of mold runner, reduced the cold burden vestige rate that causes because of the material bits, reduced because of crossing problems such as the caused burr of pressurize support size, the mould that rises, reduced the deflection of product, improved yield of products greatly, and the utility model is simple in structure, is easy to implement, and is fit to be widely used in industrial production.
