Screw rod 04 away from the big 06 05 roof. 08 stripping plate 07 spring small lever 09. Guide sleeve 10. 11 drawing board set the template file laps 13 12 14 supporting column fixed template fixed plate 16, 15 thimble thimble plate 17. 19 Floor 18 spam dynamic model slant nail lifter guides 21, 20. 23 Block 22 fixed-limit switch guide post 24. Guide sleeve 25. Spring 26 thimble 27 column 28 lifter limit fixed plate 29. Spring guide rod 30 fixed mold core positioning device 31 inserts dynamic model 32l 33 34 return scheduled punch rod 35. Scheduled to die lifter lifter fixed bottom plate 36 fixed mold material 37 pulled nail mold structure 2-chen die grapes, decided to live part of the design of two scheduled to die lifters,mulberry laukku, part of the design in the dynamic model for core pulling lifter 5, will be mode part of the slant angle is 13 degrees, dynamic simulation part of the slant angle is 3 degrees, l one. Driven to make plastic parts when the mold core in the mold release, decided to increase the 12 dam-pin 2132 pin cylinder Division, scheduled to die See lifter of the structural design of section 2.5. Dynamic simulation for the d 7 to ensure smooth ramp strength, dynamic modulus lifter structure is divided into two sections by a smooth ramp composed of inclined guides, lifter rolls NMO mounting plate ejector pin fixed deposit Bu. Spring ejection mechanism adopts the top Ⅲ reset system to ensure a stable ejection, and reliable. 4. Cooling system design of the mold cooling system according to the move, given the structural characteristics of punch and die components to layout the distribution channel. To avoid mold cooling water and related components involved in fat cows, and justice does not affect its cooling effect, decided to move, given the design of a mold core into BU 'out of the circulating cooling water, to prevent water leakage, keep moving, set the template 】: opening seal groove, the use of ring seal. 5. The structural design of fixed mold lifter lifter fixed mold structure shown in Figure 3,mulberry københavn, the entire structure from a fixed plate, the lifter floor, ramp slide Xu, pins, lifter fixed plate, on the return stroke, slant I, oblique D Page II composition. The Chinese fixed plate and set the template together by four threaded connection, the lifter with the lifter fixed bottom plate by the injection mold technology InjectionMoldTechnolo 4 laps, q, yWWW3 Lifter pins 04 slide 05. 06 return bar lifter 07 fixed plate lifter 108. Ll die lifter ramp grapes 3 pre-set structure a threaded connection in the ', the open mode, in the four spring force, the entire structure both in and outside addition to the fixed plate downward,ropa ed hardy, so that from the lifter at the Kau even in the detachment; mold, the same way bar larvae F under the action of dynamic punch to drive the lifter to the original structure of the water where the same set. Die structure and working process of the die is three plate mold and mold the human dimension as 320mmX300mmX343mm, top-il 『distance of 30mm, mold using Dragon mold die all the moving parts to ensure accurate positioning and reliable action, without catching phenomenon Gushan be tight with no loose even zero. The die working process is: move, scheduled to die Die, by the plastics material melt,ed hardy schuhe, namely, after the star into the mold through the injection machine Bian plow cavity sealed by Paul J soil, cooling, mold. Mold, in the spring 07 under the effect of stripping the fixed mold plate 06 l0 and the first slice, that is, Figure 2 A-A first and towels to separate the condensate on the template set from the given template from the material, continue to rise mold, in a small rod under the action of the stripping plate from the D Chen plate, the flow of condensate rich material stripped from the gate set rr】 continue to exercise, in large and small lever at the same time the role of divination, move, scheduled to die separately, the 2B-B separate move, scheduled to die dL,ed hardy kleider, scheduled to die oblique plastic parts in compliance from, a model to the 'given distance, the mountain-top plastic rod forward, the top institutions in the top of the mountain, led by Rod even driven punch the plastic top of a towel, while the plastic parts of the 5 upside down from the five items in the dynamic simulation of oblique extrusion, when the reach the peak of the movement away from the 30mm, remove the plastic parts and material flow condensate. Move, scheduled to die mold, the injection molding machine along the rod back, knocking out 25 of the lead agencies in the spring will be 5 _ BU lifter and 12 dynamic modules thimble, two needles reset Division tube, so that complete 'a Feng shot cycle. Conclusion The Interpretation of production proven mold, mold juice and reasonable structure design, smooth mold release, is smooth, reliable, long life molds to meet production needs, for the good economic enterprises. 【1J four reference manuals prepared plastic mold design group.
