Abstract
The utility model belongs to the technical field of molds, and particularly relates to an injection mold. The injection mold comprises a fixed mold and a movable mold arranged opposite to the fixed mold, wherein an ejection mechanism is configured on the movable mold and comprises a base, a push plate, a push plate fixing plate, and an ejector pin component extending into a product cavity; the ejector pin component comprises an ejector sleeve and an ejector pin matched with the ejector sleeve; the lower end part of the ejector sleeve is arranged on the push plate fixing plate; and the lower end part of the ejector pin is arranged on the base. The injection mold disclosed by the utility model has the advantages that the lower end part of the ejector pin is fixed, so the problem that the ejector pin is reversed when the injection molding pressure is relatively high is effectively prevented, the defect that burrs are easy to occur on the surfaces of hole edges of deep hole products is avoided and good appearance quality of the products is guaranteed.
Description
Technical field
The utility model belongs to technical field of mold, is specifically related to a kind of injection mold.
Background technology
At present; Plasthetics is widely used in electronics, automobile making and family life field; And with improving constantly of Shooting Technique, more and more stricter to the requirement of products appearance surface forming quality, this has just proposed higher standard for the formed product performance of injection mold.The structure of common plasthetics is tending towards complicated, variation, and a lot of goods all have deep-hole structures.During existing mould manufacturing is produced, the many employings of deep-hole structures department tube is ejected, still when injection pressure is higher, the situation that ejector pin falls back often occurs, cause vent surface to be prone to defectives such as burr, moulding are bad, influenced the presentation quality of goods.
The utility model content
The utility model provides a kind of injection mold, guarantee when injection pressure is higher, injection mold still has good formed product performance.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of injection mold, the dynamic model that comprises cover half, is oppositely arranged with cover half disposes ejecting mechanism on the dynamic model, and said ejecting mechanism comprises base, push pedal, push pedal fixed head and stretches into the inner ejector pin assembly of goods die cavity; Said ejector pin assembly comprises department tube, an ejector pin that cooperates with the department tube, wherein, takes charge of a bottom and is arranged on the push pedal fixed head, and the ejector pin bottom is arranged on the base.
As the advantageous embodiment of the utility model, said base lower surface offers groove, and inside grooves is provided with pressing plate, and the ejector pin bottom is connected with bridge screw.
The beneficial effect of the utility model is: the injection mold in the utility model; Employing has the ejecting mechanism of pressing plate; Ejector pin in the ejector pin assembly is fixed, effectively prevented to have avoided surface, limit, deep hole goods hole to be prone to the defective of burr because of the injection pressure problem that falling back appears in ejector pin when higher; Improve the ratio of briquetting of goods, guaranteed goods good surface appearance quality.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
Description of drawings
Fig. 1 is the structural representation of injection mold in the utility model.
Fig. 2 is the A portion enlarged drawing among Fig. 1, and the structure when the ejector pin bottom cooperates with pressing plate has been shown among the figure.
The specific embodiment
In conjunction with Fig. 1, shown in Figure 2, a kind of injection mold comprises cover half 1 and dynamic model 2, is oppositely arranged between them, forms goods die cavity 12 behind the injection mold matched moulds between cover half 1 and the dynamic model 2; Dispose ejecting mechanism on the dynamic model, in time goods are ejected from goods die cavity inside when being used for the goods demoulding.Said ejecting mechanism comprises base 3, push pedal 4, push pedal fixed head 5 and ejector pin assembly 6, said ejector pin assembly 6 comprise department tube 60, with department's ejector pin 61 that cooperates, wherein; Department tube 60 bottoms are arranged on the push pedal fixed head 5; Ejector pin 61 bottoms are arranged on the base 3, and department tube ejector pin relatively slides, and department tins 60 moves with push pedal 4; In time goods die cavity 12 inner goods are ejected, accomplish stripping process.
Preferably, said base 3 lower surfaces offer groove, and inside grooves is provided with pressing plate 7, and ejector pin 61 bottoms are connected with pressing plate 7 screws.The ejector pin bottom is fixed through pressing plate in the present embodiment; Effectively prevented because of the injection pressure problem that falling back appears in ejector pin when higher; Avoid surface, limit, deep hole goods hole to be prone to the defective of burr, improved the ratio of briquetting of goods, guaranteed goods good surface appearance mass effect.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, the utility model also be not limited in above-mentioned for example, the variation that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
Claims (2)
1. injection mold, comprise cover half, with the dynamic model that cover half is oppositely arranged, dispose ejecting mechanism on the dynamic model, it is characterized in that: said ejecting mechanism comprises base, push pedal, push pedal fixed head and stretches into the inner ejector pin assembly of goods die cavity; Said ejector pin assembly comprises department tube, an ejector pin that cooperates with the department tube, wherein, takes charge of a bottom and is arranged on the push pedal fixed head, and the ejector pin bottom is arranged on the base.
2. a kind of injection mold according to claim 1 is characterized in that: said base lower surface offers groove, and inside grooves is provided with pressing plate, and the ejector pin bottom is connected with bridge screw.
