Abstract
The utility model discloses a plastic mold provided with an angle pin, which comprises a fixed mold, a movable mold, the angle pin and an ejector pin mechanism. The fixed mold and the movable mold are matched to form a cavity, an angle pin hole is arranged on the fixed mold, the angle pin penetrates through the angle pin hole, and one end of the angle pin extends into the cavity while the other end is connected with the ejector pin mechanism. The plastic mold is characterized in that a groove parallel to a moving direction of the angle pin is arranged on a lateral wall of the angle pin hole, the depth of the groove ranges from 0.3 millimeter to 0.6 millimeter, and one end portion of the groove which is arranged on the surface of the cavity of the fixed mold is closed. The plastic mold reduces friction resistance when the angle pin moves, simultaneously provides storage space of lubricating grease and is more favorable for lubricating the angle pin, and the angle pin is smooth in operation without being broken, thereby saving large quantities of mold repair cost and mold repair time, and avoiding loss caused by interrupted production.
Description
Technical field
The utility model relates to a kind of use in injection molding mould of plastics, is specifically related to a kind of mould of plastics that is provided with inclined pin structure.
Background technology
When the sidewall of working of plastics had structures such as through hole, depression, boss, its forming part must be made and can be displaced sideways, so that the demoulding.Inclined pin structure is exactly a kind of structure that realizes the side direction demoulding.Usually, offer the taper pin hole on cover half, taper pin passes the taper pin hole, and an end stretches into die cavity, and the other end is connected with ejector pin mechanism, and rare occasion also has taper pin to be located on the dynamic model.Utilize injection mold to carry out in the process of injection moulding production, taper pin serves as that guiding ejects, retraction operation with the taper pin hole, and shown in accompanying drawing 1, after mould was opened, taper pin 1 can be ejected and retract by thimble 2, thereby reached the purpose that ejects with the side direction products of separated.In the prior art, taper pin and taper pin hole are that 0.01mm cooperates with the gap, when producing distortion between taper pin and the taper pin hole or producing chip, the resistance of taper pin operation can become big, even be stuck, thereby taking place, operation not freely, also the situation that taper pin fractures often takes place, this situation can cause mould to sustain damage, the generation expense that repairs a die, and have a strong impact on the normal volume production of mould.
Summary of the invention
The utility model purpose provides a kind of mould of plastics that is provided with taper pin that improves structure, makes the taper pin operation smooth and easy, is difficult for taking place the situation that taper pin fractures.
For achieving the above object, the technical solution adopted in the utility model is: a kind of mould of plastics that is provided with taper pin, comprise cover half, dynamic model, taper pin and ejector pin mechanism, cooperate between the fixed half and moving half and constitute die cavity, on described cover half, offer the taper pin hole, described taper pin passes the taper pin hole, one end stretches into die cavity, the other end is connected with ejector pin mechanism, the sidewall in described taper pin hole is provided with the groove parallel with the taper pin direction of motion, groove depth is 0.3～0.6 millimeter, and described groove is in the sealing of the mold cavity surface one end end of cover half.
Above, similar in the described mould of plastics with prior art, be provided with flow passage structure, ejecting structure, guide frame and cooling structure.The use of mould of plastics that is provided with taper pin in the using method of mould of plastics and the prior art is identical.
In the technique scheme, on each sidewall in described taper pin hole, be provided with a described groove at least.
Further technical scheme is provided with a described groove at each bar rib place in described taper pin hole.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1. the utility model is provided with groove on the sidewall in taper pin hole, makes the contact area in taper pin and taper pin hole reduce, the frictional resistance when having reduced the taper pin operation; The memory space of lubricant grease is provided simultaneously, has more helped the lubricated of taper pin;
2. the setting of groove structure for the chip of generation in service provides the space of depositing, makes that the taper pin operation is smooth and easy;
3. at each bar rib place in taper pin hole a groove is set, allows the seamed edge of taper pin not be squeezed, when taper pin has slight deformation, can provide to allow bit space, avoid taper pin to be stuck;
4. taper pin operation of the present utility model is smooth and easy, can not fracture, and has saved a large amount of expenses that repairs a die and has repaired a die the time, has avoided being interrupted the loss that is caused because of producing.
Description of drawings
Fig. 1 is the structural representation (part is analysed and observe) that is provided with the mould of plastics of taper pin in the prior art;
Fig. 2 is the partial schematic sectional view of cover half and inclined pin structure among the utility model embodiment one;
Fig. 3 is that the A-A among Fig. 2 analyses and observe enlarged diagram;
Fig. 4 is that the B-B behind the removal taper pin analyses and observe enlarged diagram among Fig. 2.
Wherein: 1, taper pin; 2, thimble; 3, groove; 4, taper pin hole.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: shown in accompanying drawing 2 and accompanying drawing 3, a kind of mould of plastics that is provided with taper pin, comprise cover half, dynamic model, taper pin 1 and ejector pin mechanism, cooperate between the fixed half and moving half and constitute die cavity, on described cover half, offer taper pin hole 4, described taper pin 1 passes taper pin hole 4, one end stretches into die cavity, the other end is connected with ejector pin mechanism, the sidewall in described taper pin hole 4 is provided with many grooves 3 parallel with taper pin 1 direction of motion, groove depth is 0.5 millimeter, and described groove is in the sealing of the mold cavity surface one end end of cover half.
The width and the quantity of fluting can be decided on the size of actual taper pin, shown in accompanying drawing 3, in the present embodiment, offer a groove at every rib place in taper pin hole, offer one to two groove on each sidewall.As seen from the figure, the contact area in taper pin and taper pin hole can reduce, and the groove at taper pin seamed edge place is in order to the bit space that allows of taper pin micro-strain, and the groove of increasing can be used as the memory space of lubricating oil, the parking space of the chip that produces when also can be used as mold work.The improvement of these several aspects has been arranged, and taper pin just can move smooth and easy, reduces wear, and can not fracture.
Referring to accompanying drawing 2, the end of the groove of increasing should be lower than die surface, and promptly mold cavity surface one end at cover half seals, otherwise the plastic cement of fusion can flow into the groove of increasing in the die cavity.
