Abstract
The invention discloses a special mould stripping mechanism of an injection mould. The special mould stripping mechanism comprises an ejector pin, a large slide block, an inclined guide post, a lock block, a small slide block and a movable mould core, wherein a groove is formed in the right side of the movable mould core; the small slide block is matched with the groove; the bottom surface of the large slide block is matched with the small slide block; the right side inclined surface of the large slide block is matched with the lock block; the inclined guide post is fixed inside the lock block, and is matched with a right side inclined hole in the large slide block; and the ejector pin is matched with the movable mould core. The special mould stripping mechanism solves the problem that a back-off boss and a back-off rib for a formed product are difficult in mould stripping, and is greatly improved in technology; after the inverted-U-shaped product is formed and subjected to mould stripping, two sides of the product are deformed towards the middle part; by virtue of the small slide block, the right side of the product is pulled outwards and deformed, so that the possibility that the two sides of the product are deformed towards the middle part after being subjected to mould stripping can be reduced; by virtue of the back-off mould stripping mode, development capacity of the mould is improved, mould opening cost is reduced, and a development period of the mould is shortened. The special mould stripping mechanism belongs to the technical field of mould equipment.
Description
Technical field
The present invention relates to injection mold technical field, be specially the knock-out gear that a kind of injection mold is special.
Background technology
Injection mold is the one in mould, application very general, especially uses at most at some working of plastics products of making.Product 1 is in inverted U as shown in Figure 1, the medial surface of product 1 has reinforcement 1.1. back-off boss 1.2 and back-off muscle 1.3, if the way that back-off position is conventional and weak point first back-off position adopt large oblique top, then can produce with reinforcement 1.1 during large lifter ejection and interfere, designing large oblique top is false; It two is that suggestion client cancels reinforcement 1.1; still large oblique top is adopted; and design ejects protective device and clings large oblique top when ejecting to prevent product in large oblique top; the shortcoming wherein existed is that the product area in large oblique top is excessive; large oblique top must increase cooling water channel to prevent large oblique top overheated; to account for a lot of space because design in large oblique top ejects protective device, design space, water route is narrow, thus adds die sinking cost.
Summary of the invention
Technical problem to be solved by this invention is the knock-out gear providing a kind of injection mold special; comprise thimble, large slide block, Angle Pin, lock dog, small slide block and mavable module core; fluted on the right side of described mavable module core; small slide block and groove fit; the bottom surface of large slide block coordinates with small slide block, and the inclined-plane, right side of large slide block coordinates with lock dog, and Angle Pin is fixed on inside lock dog; and coordinate with the right side inclined hole on large slide block, thimble coordinates with mavable module core.
As preferably, a left side for described small slide block then offsets with mavable module core, and right side and large slide block offset.
As preferably, Zola's hook of described small slide block forms die cavity with mavable module core and large slide block respectively, and the step on right drag hook and large slide block has the space of a segment distance.
As preferably, described lock dog is fixed on solid plate.
Beneficial effect: the present invention establishes the injection mold postponing drag hook type small slide block pull-out product inner reverse fastener in a kind of large slide block inside, solves the problem of shaped article back-off boss and this structure depanning of back-off muscle difficulty, technically has larger leap; After this formed product depanning in inverse u shape, product both sides all can to intermediate deformation, and the small slide block in the present invention is by the distortion that pulls outward on the right side of product, and after can reducing product depanning, both sides are toward intermediate deformation; This back-off depanning mode, improves the development ability of mould, reduces die sinking cost, shorten the construction cycle of mould.

Detailed description of the invention
Fig. 1-8 is depicted as related description figure of the present invention; The knock-out gear that a kind of injection mold is special; comprise thimble 2, large slide block 3, Angle Pin 4, lock dog 5, small slide block 6 and mavable module core 7; on the right side of described mavable module core 7 fluted 7.1; small slide block 6 coordinates with groove 7.1, and the bottom surface of large slide block 3 coordinates with small slide block 6, and the inclined-plane, right side of large slide block 3 coordinates with lock dog 5; Angle Pin 4 is fixed on inside lock dog 5; and coordinate with the right side inclined hole 3.2 on large slide block 3, thimble 2 coordinates with mavable module core 7, as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5.
A left side for described small slide block 6 then offsets with mavable module core 7, and right side and large slide block 3 offset, as shown in Figure 5.
Zola's hook 6.1 of described small slide block 6 forms die cavity with mavable module core 7 and large slide block 3 respectively, and right drag hook 6.2 and the step 3.1 on large slide block 3 have the space of a segment distance, as Fig. 2, Fig. 3, Fig. 5.
Described lock dog 5 is fixed on solid plate, as shown in Figure 5.
During real work, as shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8, its motion operation principle: during die sinking, Angle Pin 4 drives large slide block 3 to slide to the right a segment distance, the right drag hook 6.2 of small slide block 6 contacts with the step 3.1 on large slide block 3, as shown in Figure 5. then large slide block 3 continues to move right, and the right drag hook 6.2 that the step 3.1 simultaneously on large slide block 3 is held on small slide block 6 moves right together; Meanwhile, the back-off muscle 1.3 that the Zola's hook 6.1 on small slide block 6 hauls on product 1 moves right, and back-off muscle 1.3 and back-off boss 1.2 all depart from mavable module core 7, and now product 1 is drawn as deformation state, as shown in Figure 6.After Angle Pin 4 departs from large slide block 3, product 1 is ejected mavable module core 7 by thimble 2, and after product 1 departs from mavable module core 7 completely, product 1 becomes normal condition from deformation state resilience.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
