The specific embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.

See also Fig. 2 and Fig. 3; The utlity model has the mould of slide block mechanism; Be used for product 30, the first barbs 31 with first barb 31 and second barb 32 as shown in Figure 1 and be formed at the top of said product 30, and be vertical direction; Second barb 32 is formed at the bottom of said product 30, and is formed obliquely to the upper left side.

Particularly; Said mould with slide block mechanism comprises upper mounted plate 10, caster 12, mother module core 14, male model plate 16, male model benevolence 18, guide pillar 20 and slide block mechanism 22; Said mother module core 14 is arranged at said caster 12, and said male model benevolence 18 is arranged at said male model plate 16, and said caster 12 cooperatively interacts with male model plate 16; Said guide pillar 20 is obliquely to be installed; And an end of said guide pillar 20 is installed on said caster 12, and the other end of said guide pillar 20 is slidably inserted into said slide block mechanism 22, and said slide block mechanism 22 is installed on said male model plate 16.

Wherein, Said slide block mechanism 22 comprises take-up housing 221, first slide block 222, second slide block 223, locating part 224 and return unit 225; The other end of said guide pillar 20 is slidably inserted into said take-up housing 221 and drives said take-up housing 221 and moves; Said take-up housing 221 is installed on said male model plate 16, and said first slide block 222 is installed on said take-up housing 221, and said second slide block 223 is installed on said first slide block 222 slidably; Said first slide block 222 is used for said second barb 32 of moulding; Said second slide block 223 is used for said first barb 31 of moulding, and an end of said locating part 224 is installed on said take-up housing 221, and the other end of said locating part 224 is installed on said second slide block 223 slidably; One end of said return unit 225 is installed on said take-up housing 221, the other end of the said return unit 225 said male model benevolence 18 of conflicting.

Preferably, in the present embodiment, said locating part 224 is a pull bar, and said return unit 225 is a spring.

See also Fig. 4 to Fig. 7, described the knockout course that the mould that the utlity model has slide block mechanism is accomplished the product with two barbs smoothly.As shown in Figure 4; After adopting said mould to accomplish injection moulding, before the die sinking with slide block mechanism; The major part of said guide pillar 20 is inserted said take-up housing 221, an end of the said second slide block 223 said take-up housing 221 of conflicting, and the other end of said second slide block 223 engages with said first barb 31; Said first slide block 222 engages with said second barb 32, and said return unit 225 is in compressive state and has outside elastic restoring force.Carry out die sinking afterwards; At first separate said caster 12 and male model plate 16; As shown in Figure 5, said caster 12 drives said guide pillar 20 and moves upward, under the help of the elastic restoring force of said return unit 225; Said guide pillar 20 drives said take-up housings 221 and first slide block 222 to the motion of diagram A direction, so that said first slide block 222 breaks away from and the engaging of said second barb 32; In this process; Said first slide block 222 drives said second slide block 223 to the motion of diagram B direction; One end of said second slide block 223 breaks away from the conflict with said take-up housing 221, the other end disengaging of said second slide block 223 and engaging of said first barb 31.Afterwards; The said take-up housing 221 and first slide block 222 continue to the motion of diagram A direction; Said second slide block 223 continues to the motion of diagram B direction; When the sliding distance of said second slide block 223 received the maximum tension distance limit of said locating part 224, said first slide block 222 will continue to drive said second slide block and continue finally to reach standard-sized sheet mould state as shown in Figure 6 to the motion of diagram A direction.At last,, therefore can successfully said product 30 be ejected because of first barb 31 of said product 30 separates with said second slide block 223 and first slide block 222 with second barb 32 respectively, as shown in Figure 7.

As stated, the mould that the utlity model has slide block mechanism can be accomplished the demoulding of the product 30 with first barb 31 and second barb 32 smoothly, and simple in structure.
