It is slidably connected between extending portion by guide frame, delay unit, the delay unit is provided between described big sliding block and small pulling block
Small pulling block can be limited within the certain distance that big sliding block moves out to move out, and set between described big sliding block and extension
There is driving structure, the driving structure can be used to draw small pulling block together to outward transport when big sliding block moves outwardly to certain distance
It is dynamic.
In above-mentioned one kind hales mould emptier, the bearing of trend of the extension and the outside direction of motion of big sliding block
Parallel, described driving structure is included located at the guiding groove of big slider bottom and the spacing preiection on extension, described
Guiding groove along extension length direction extension, described spacing preiection stretch to be oriented to groove in and can along be oriented to groove
Length direction motion, the spacing preiection described in when described big sliding block abuts in plastic outer body face be resisted against be oriented to it is recessed
One end away from small pulling block in groove.
In above-mentioned one kind hales mould emptier, described delay unit is spring, when described big sliding block abuts in
The lateral surface of plastic body and when small pulling block abuts in the medial surface of plastic body, described spring is in compressive state.
In above-mentioned one kind hales mould emptier, described guide frame includes the chute for being symmetrically set in extension both sides
One extends with chute two, the chute one with length direction of the chute two along extension, and the bottom of the big sliding block is fixed with slide
One has the slide rail one stretched in chute one with slide two, the sidepiece of the slide one, and the sidepiece of the slide two, which has, to be stretched
Enter to the slide rail two in chute two.Can only be along prolonging with limiting big sliding block in the presence of slide rail two in chute one, chute two, slide rail one
The length direction motion of extending portion.
In above-mentioned one kind hales mould emptier, described slide one is bolted on big sliding block with slide two
Bottom.
In above-mentioned one kind hales mould emptier, described small pulling block is 2-3.
In above-mentioned one kind hales mould emptier, described small pulling block is 3.
Originally the operation principle for haling mould emptier is as follows：When mould molds, big sliding block elder generation core pulling certain distance is that is, big sliding
Block moves along extension away from small pulling block, the dermatoglyph region of plastic body appearance is departed from big sliding block, and spring reset extends,
Small pulling block is promoted to remain stationary as under elastic force effect, until small pulling block contacts limit point (according to the back-off size of product different piece
Size and location set the limit point of different distance), when guiding groove is abutted on spacing preiection close to one end of small pulling block,
Big sliding block drives extension to move out together, so as to drive small pulling block to hale with different distances the side of plastic body, gently
Pine makes the large area back-off structure of plastic body medial surface depart from punch-pin, is finally ejected plastic body by ejection system, completes
The demoulding.
Compared with prior art, originally haling mould emptier has advantages below：
Drive small pulling block to hale using the delay of big sliding block to be stripped, can easily realize the big of plastic bulk product complexity
The demoulding of area multiple location back-off structure, and the outward appearance of product can be kept in shape；It is safe and reliable to operation, it is effectively ensured
The mold use life-span.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
It is as shown in Figure 1 to hale mould emptier, including big sliding block 2 positioned at the lateral surface of plastic body 1 and positioned at plastic sheet
The small pulling block 3 of the medial surface of body 1, as shown in Fig. 2 the lower end of small pulling block 3 has the extension 4 for extending to the big bottom of sliding block 2.This reality
Apply in example, be slidably connected between big sliding block 2 and extension 4 by guide frame, delay is provided between big sliding block 2 and small pulling block 3
Unit, the delay unit can limit small pulling block 3 within the certain distance that big sliding block 2 moves out and move out, big sliding block 2 with
Driving structure is provided between extension 4, the driving structure can be used to draw small drawing when big sliding block 2 moves outwardly to certain distance
Block 3 moves out together.
As shown in Figure 3 and Figure 4, the bearing of trend of extension 4 is parallel with the direction of motion that big sliding block 2 is outside, driving structure
Including being oriented to groove 51 and the spacing preiection 52 on extension 4 located at the big bottom of sliding block 2, groove 51 is oriented to along extension
4 length direction extension, spacing preiection 52, which stretches to, to be oriented in groove 51 and can be moved along the length direction for being oriented to groove 51, when
Spacing preiection 52, which is resisted against, when big sliding block 2 abuts in plastic 1 lateral surface of body is oriented to one end away from small pulling block 3 in groove 51.
In the present embodiment, delay unit is spring, when big sliding block 2 abuts in the lateral surface of plastic body 1 and small pulling block 3 pastes
When leaning against the medial surface of plastic body 1, spring is in compressive state.
As shown in Figures 2 and 3, guide frame includes the chute 1 and chute two for being symmetrically set in the both sides of extension 4, the cunning
The length direction of groove 1 and chute two along extension 4 extends, as shown in Fig. 2 the bottom of big sliding block 2 be fixed with slide 1 with
Slide two, the sidepiece of slide 1 have the slide rail one stretched in chute 1, and the sidepiece of slide two, which has, stretches to chute
Slide rail two in two.Limiting big sliding block 2 in the presence of chute 1, chute two, slide rail one and slide rail two can only be along extension 4
Length direction motion.
As shown in Fig. 2 slide 1 is bolted on the bottom of big sliding block 2 with slide two.
In the present embodiment, as shown in Fig. 2 small pulling block 3 is 3.
Originally the operation principle for haling mould emptier is as follows：When mould molds, the big first core pulling certain distance of sliding block 2 is that is, big
