Abstract
The invention discloses a T-shaped core-pulling mechanism of an injection mould. The T-shaped core-pulling mechanism comprises a core-pulling sliding block, a locking block, inclined guide pillars, a bottom sliding block, a side edge sliding block and T-shaped sliding rails, wherein the lower part of the core-pulling sliding block is provided with a slant T-shaped sliding groove, and the side part of the core-pulling sliding block is provided with the sliding rail; the upper part of the bottom sliding block is provided with the slant T-shaped sliding rail, the lower part of the bottom sliding block is provided with a T-shaped sliding groove, and the side part of the side edge sliding block is provided with a sliding groove; the slant T-shaped sliding groove formed in the lower part of the core-pulling sliding block is formed in the T-shaped sliding rail arranged on the bottom sliding block, and the T-shaped sliding groove formed in the lower part of the bottom sliding block is formed in the T-shaped sliding rail; the sliding groove formed in the side part of the side edge sliding block is formed in the sliding rail arranged on the side part of the core-pulling sliding block, the inclined guide pillars are sleeved in bottom sliding block holes, locking block buckles the bottom sliding block and the core-pulling sliding block, and the T-shaped core-pulling mechanism is characterized in that the core-pulling sliding block is drawn out along the sliding groove in an inclined upward manner. The T-shaped core-pulling mechanism provided by the invention has the advantages that the design is reasonable, the defect of the prior art is overcome, the downward and inclined-rear-direction resultant movement of the core-pulling sliding block is realized, the smooth and reliable demoulding of the T-shaped core-pulling mechanism is guaranteed, and the purposes that the volume of a mould is reduced and the cost of the mould is reduced are achieved.
Description
Technical field
The present invention relates to the plastic automotive parts injection mold, relate in particular to injection mold T shape core-pulling mechanism.
Background technology
Injection mold is widely used a kind of mould in plastics industry, mainly by running gate system, guidance system, formation system, the compositions such as cooling system and ejecting mechanism, for complex-shaped, product has side opening, side recessed, can not directly eject, must pass through pulled core structure, or the pitched roof mechanism ejecting product.Along with the progress of mold machining technology level, now more and more higher to the product appearance requirement, a lot of product surfaces require the dermatoglyph effects, and the injection defects such as push rod vestige, plucking, scuffing, scratch must not be arranged.The balance of product in injection moulding process, to eject smoothly be the key issue of injection moulding production process.
Summary of the invention
Defect for above-mentioned prior art core-pulling mechanism for injection mold, the object of the present invention is to provide a kind of injection mold T shape core-pulling mechanism, with Angle Pin, loose core, by the base slider of core-pulling slide block and two chutes of side, realize core-pulling slide block downwards and oblique rear to resultant motion, mould core pulling is resetted stable, reliable.
Technical scheme of the present invention is: a kind of injection mold T shape core-pulling mechanism, be included as core-pulling slide block, latch segment, Angle Pin, base slider, side slide block and T shape slide rail, the core-pulling slide block bottom is provided with oblique T shape chute, sidepiece is provided with slide rail, base slider top is provided with oblique T shape slide rail, bottom is provided with T shape chute, side slide block sidepiece is provided with chute, core-pulling slide block bottom oblique T shape chute, be assemblied on base slider upper T shape slide rail, base slider bottom T shape chute, be assemblied on T shape slide rail, side slide block sidepiece chute, be assemblied on core-pulling slide block sidepiece slide rail, Angle Pin is enclosed within the base slider hole, the latch segment snap close is lived base slider and core-pulling slide block, it is characterized in that: core-pulling slide block is extracted out obliquely upward along chute.
The present invention, reasonable in design, overcome the defect of prior art, realize core-pulling slide block downwards and oblique rear to resultant motion, guarantee the demoulding smoothly, reliable, the present invention is simple in structure, reaches and reduces the mould volume, reduces the purpose of die cost.
The accompanying drawing explanation
Fig. 1 core-pulling mechanism structural representation of the present invention;
Fig. 2 core-pulling mechanism of the present invention decomposing schematic representation of loosing core;
In above accompanying drawing: the 1-core-pulling slide block; The 2-latch segment; The 3-Angle Pin; The 4-base slider; 5-side slide block; 6-T shape slide block.
The present invention is further illustrated below in conjunction with drawings and Examples.
The specific embodiment
As shown in Figure 1, injection mold T shape core-pulling mechanism of the present invention, slide rail and chutes by many groups of corresponding assemblings cooperatively interact, and realize that mould is two-way to take out, and it is included as core-pulling slide block 1, latch segment 2, Angle Pin 3, base slider 4, side slide block 5 and T shape slide rail 6.Core-pulling slide block 1 bottom be provided with slope (to) T shape chute, sidepiece is provided with slide rail, base slider 4 tops be provided with slope (to) T shape slide rail, bottom is provided with T shape chute, side slide block 5 sidepieces are provided with chute.Core-pulling slide block 1 bottom oblique T shape chute, be assemblied on base slider 4 upper T shape slide rails, base slider 4 bottom T shape chutes, be assemblied on T shape slide rail 6, side slide block 5 sidepiece chutes, be assemblied on core-pulling slide block 1 sidepiece slide rail, Angle Pin 3 is enclosed within base slider 4 holes, and latch segment 2 snap closes are lived base slider 4 and core-pulling slide block 1.
During moving, cover half matched moulds, latch segment 2 and base slider 4 stick together, and base slider 4 core-pulling slide block 1 of ining succession, be now locking state, and mould can injection molding; As shown in Figure 2, during moving, cover half parting, latch segment 2 separates with base slider 4, base slider 4 is moved along T shape slide rail 6 by the power of Angle Pin 3 backward, core-pulling slide block 1 down moves along the oblique below chute on base slider 4, simultaneously along the oblique chute on dual-side slide block 5 toward tiltedly reverse, realize thus core-pulling slide block 1 downwards and oblique rear to resultant motion.
