AI Technical Summary
When the existing Haval slider mold is opened, it is difficult for the product and gate to be separated automatically, which can easily cause gate to remain or damage the product, affecting product quality, and adding auxiliary equipment will increase costs and production cycles.
A mold for automatic gate cutting of the gate with a differential opening Haval type slider is designed. By setting up structures such as sliders, partition plates, step surfaces, thimbles and return springs, the ejection mechanism is used to realize automatic separation of the gate and the product in the closed state of the slider.
Automatic separation between the gate and the product is achieved, ensuring that there is no residue in the gate section cutout, simplifying the mold structure, and in the absence of inclined guide columns, oil cylinders or cylinders, the slider stroke is achieved by ejecting the slider block and pulling it out.

Abstract
Description
Technical Field
[0001] The utility model relates to a mould, in particular to a mould with a differentially opened Haversian slide block for automatically cutting off a gate. Background Art
[0002] Usually, the glue of the Haval slider is directly injected from the slider parting surface. When the mold is opened, the inclined guide column drives the slider to disengage and undercut. At this time, the product and the gate will still be connected. If the mold is automatically separated by a delayed ejection mechanism, a large gate residual area will occur, and the gate is easy to damage the product, affecting product quality. If other auxiliary equipment is added and post-processing is performed to achieve automatic separation, the cost and production cycle will increase, which is not conducive to production. Utility Model Content

[0007] An 8mm delay distance is arranged between the slider and the slider puller, and the slider and the slider puller are in inclined contact.
[0008] The beneficial effects of the utility model are as follows: the structure is novel, and the gate and the product are automatically separated when the slider is closed by ejection, ensuring that there is no residue on the gate section cut, simplifying the mold structure, and realizing the outward sliding of the slider stroke by ejecting the slider puller in the absence of inclined guide columns, oil cylinders, and air cylinders. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] A differential ejector-type Haversian slider automatically cuts off a gate mold, comprising a lower fixed plate 16 and a male mold plate 17 arranged parallel to each other, a slider 15 is arranged on the upper part of the male mold plate 17, two spacer plates 14 are arranged opposite to each other between the lower fixed plate 16 and the male mold plate 17, a step surface is arranged opposite to the middle position of the two spacer plates 14, a second ejector bottom plate 6 and a second ejector panel 7 are arranged horizontally on the step surface, a first ejector bottom plate 4 and a first ejector panel 5 are arranged between the lower parts of the two spacer plates 14, and a first ejector bottom plate 4 and a first ejector panel 5 are arranged between the lower parts of the two spacer plates 14. A first sprue ejector 1, a second sprue ejector 2 and a slider block 3 are vertically fixed on an ejector panel 5, the top of the slider block 3 passes through the inclined hole of the slider 15, a product forming ejector 18 is vertically provided on the second ejector panel 7, a first return pin 10 is provided between the first ejector panel 5 and the male template 17, a first return spring 11 is sleeved on the outside of the first return pin 10, a second return pin 12 is provided between the second ejector panel 7 and the male template 17, a second return spring 13 is sleeved on the outside of the second return pin 12.
[0012] like Figure 1 and Figure 2 As shown, the mold of the present application is designed with two sets of ejection mechanisms. The first set of ejection mechanisms includes: a first sprue ejector pin 1 , a second sprue ejector pin 2 and a slider block 3 which are all fixed on a first ejector panel 5 .
[0013] The partition plate 14 is stepped, with a step surface in the middle thereof, a second ejector base plate 6 and a second ejector panel 7 being horizontally arranged on the step surface, and a product forming ejector 18 being vertically arranged on the second ejector panel 7, which is a second set of ejection mechanisms.
[0014] When working: Each set of ejection mechanism is designed with a separate reset spring and return pin (respectively: the first return pin 10 and the first reset spring 11, the second return pin 12 and the second reset spring 13), and there is an 8mm delay distance between the slider 15 and the slider puller 3, that is, when the first set of ejection mechanism is ejected to 8MM, the slider 15 is in a tight state and does not move, and the ejection realizes the automatic cutting of the gate, and the cross-sectional effect is the same as the latent gate. As the mold continues to eject, the slider puller 3 drives the slider 15 to gradually disengage from the undercut. When the first set of ejection mechanism hits the second set of ejection mechanism, the slider 15 undercut is completely disengaged, and the product that continues to be ejected automatically falls off. The two sets of ejection mechanisms are automatically reset by the reset spring. When the mold is closed, the locking block 8 forces the Hafe slider (slider 15) to reset into the mold.
[0015] After the implementation of the scheme of the present application, the gate and the product are automatically separated when the slider 15 is closed by ejection, ensuring that there is no residue on the gate section cut, simplifying the mold structure, and in the absence of inclined guide columns, oil cylinders, and air cylinders, the slider 15 can slide outward by ejecting the slider puller.
[0016] A locking block 8 is provided on the outer side of the slider 15, and the slider 15 and the locking block 8 are in inclined contact. A positioning groove 1501 is provided on the upper part of the male template 17, and a limiting protrusion 801 is provided on the lower part of the locking block 8 for positioning with the inclined surface of the positioning groove 1501.
[0017] There is an 8 mm delay distance between the slider 15 and the slider block 3 , and the slider 15 and the slider block 3 are in inclined contact.
