Specific embodiment

It is with reference to the accompanying drawing and specific real to make those skilled in the art better understand the technical solution of the utility model Mode is applied to elaborate to the utility model.

As shown in Figures 1 to 4, the embodiments of the present invention disclose a kind of injection moulding apparatus, which includes fixed Mould 10 and dynamic model 20, cover half 10 and dynamic model 20 offer continuous die cavity, as shown in Figure 1, when dynamic model 20 moves to and cover half When the state of 10 fastenings, the die cavity successively arranged is formed between dynamic model 20 and cover half 10, being can be complete by an injection port At the casting of all die cavitys, so that being connected between two neighboring die cavity using duct 50, to be completed by the duct 50 to all The casting of die cavity, by obtaining the multiple mouldings 100 being connected to the cooling of casting raw material.In the present invention, exist Dynamic model 20 is provided with cutting mechanism 30, which is arranged in position corresponding with duct 50, and each duct 50 is right A cutting mechanism 30 is answered, which includes rod-shaped cutter 34 and driving assembly, so that cutter 34 is being driven It can be moved towards the direction perpendicular to duct 50 when dynamic Component driver, in this way, after the moulding 100 being located in die cavity is cooling, The material in duct 50 is cut off using cutter 34, so that separating between the adjacent moulding 100 of every two.

The utility model utilizes the cutter 34 in the cutting mechanism 30 corresponding to 50 position of duct to make the note being cooled and shaped Plastic 100 is just realized before being opened and is automatically cut off, and then connected moulding 100 is avoided to carry out again after taking out in die cavity Cutting.

Driving assembly in cutting mechanism 30 specifically includes: as shown in Figure 2 and Figure 4, cylinder 31, first piston 32, first Spring 33.The position corresponding with duct 50 of dynamic model 20 offers the first mounting hole of perforation.31 head of cylinder stretches to the first peace It fills in hole；First piston 32 is set in cylinder 31 and can move along cylinder 31 towards the direction close to or far from duct 50, The tail portion of cutter 34 is connected to first piston 32；First spring 33 is set between the head of cylinder 31 and first piston 32；Gas The tail portion of cylinder 31 with the tracheae with pressed gas for connecting, to drive first piston 32 when pressed gas enters cylinder 31 When, cutter 34 vertically cuts off duct 50；Duct 50 is the duct 50 of the rectangular section surrounded by dynamic model 20 and cover half 10.In this reality It applies in example, is moved using pressed gas driving cutter 34, each cutter 34 is enabled to share an air pump and realize to cut off making Industry.When cutter 34 is protruded into cut off the connecting portion of moulding 100, stop being passed through pressed gas for cylinder 31, in the first bullet Under the action of spring 33, cutter 34 bounces back in the position flushed with the inner wall of dynamic model 20.

In a preferred embodiment of the utility model, as shown in Figure 2 and Figure 4, the position corresponding with duct 50 of cover half 10 The second mounting hole for offering perforation is set, one end that the second mounting hole is located inside is formed with avoid holes, and injection moulding apparatus further includes Avoiding mechanism 40；Avoiding mechanism 40 includes: cylinder 41, second piston 42, cylinder 45, lid 44 and second spring 43.Wherein, 41 head of cylinder stretches in the second mounting hole；Second piston 42 be set in cylinder 41 and can along cylinder 41 towards close or Direction far from duct 50 is mobile；Cylinder 45 is connected to second piston 42；Lid 44 is fixed on the tail portion of cylinder 41；Second spring 43 are set between lid 44 and second piston 42 for making cylinder 45 stretch to the inner wall in avoid holes and with cover half 10 It flushes.In this way, cutter 34 passes perpendicularly through duct 50 and pushes against cylinder 45 and returns when needing to cut off the link position of moulding 100 It contracts so that cutter 34 stretches to avoid holes, and after the retraction of cutter 34, under the action of second spring 43, cylinder 45 protrudes into again To avoid holes and head is flushed with the inner wall of cover half 10.Advantage of this embodiment is that: on the one hand, cutter 34, which stretches to, to be avoided Kong Hou so that the material close to the position of the inner wall of cover half 10 is cut off completely, and then is avoided after completing cutting operation, moulding There is also part connectivity problems between 100；On the other hand, the retraction of cylinder 45 avoids or alleviates 34 head of cutter and cover half The impact of 10 inner walls, and then prevent 34 head of cutter from damaging.

Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new In the protection scope of type.
