When the existing mold ejection device works, the condition of damaging a plastic part is very easy to occur, so that the production of the plastic part is greatly influenced.
SUMMERY OF THE UTILITY MODEL
In view of the above problem, an object of the utility model is to provide a mold ejection device aims at solving the problem that current mold ejection device damages the plastic part easily.
The utility model adopts the following technical scheme:
the mold ejection device comprises a base and an ejector plate above the base, a mold base is arranged above the ejector plate, a spring is arranged on the base, the spring is connected with a flat ejector pin, the flat ejector pin penetrates out of the ejector plate, a through hole is formed in the position, corresponding to the flat ejector pin, of the mold base, the flat ejector pin is inserted into the through hole, and a limiting mechanism for limiting the flat ejector pin to move is further arranged on the base.
Further, stop gear is including fixed cover and movable sleeve, fixed cover is fixed in the base, the spring is located the movable sleeve, flat thimble bottom is located the movable sleeve and contradicts to the spring top.
Furthermore, a supporting block is arranged between the spring and the bottom of the flat thimble.
Further, the bottom surface of base is opened there are two mounting grooves, every all install the bottom plate in the mounting groove, every the bottom plate upside is connected with two movable sleeves, the bottom plate passes through screw locking to mounting groove.
The utility model has the advantages that: the utility model provides a mould ejecting device, flat thimble among this mould ejecting device can be at the effect of spring ejecting piece of moulding that makes progress down, and stop gear on the base can restrict flat thimble rebound simultaneously, has effectively prevented that flat thimble from crashing the piece of moulding.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
Only portions related to the embodiments of the present invention are shown for convenience of explanation.
Combine fig. 1, fig. 3 and fig. 5 to show, mould ejecting device includes the thimble board 5 of base 1 and base 1 top, thimble board 5 top is provided with mould seat 2, be provided with spring 3 on the base 1, spring 3 is connected with flat thimble 4, thimble board 5 is worn out to flat thimble 4, it has through-hole 21 to correspond the position with flat thimble 4 on the mould seat 2, flat thimble 5 inserts in the through-hole 21, still be provided with the stop gear 6 that restricts flat thimble 4 and remove on the base 1.
The spring acts on the plastic part through the flat thimble, and the spring drives the flat thimble and the molded plastic part to move upwards, and the flat thimble moves in the through hole on the die holder, and the flat thimble stops moving after moving a certain height because the flat thimble receives the restriction of stop gear to realized avoiding the flat thimble to hit and damage the plastic part.
As shown in fig. 2 to 5, as a preferred structure, the limiting mechanism 6 includes a fixed sleeve 61 and a movable sleeve 62, the fixed sleeve 61 is fixed on the base 1, the spring 3 is located in the movable sleeve 62, and the bottom of the flat thimble 4 is located in the movable sleeve 62 and abuts against the top of the spring 3. And a supporting block 7 is arranged between the spring 3 and the bottom of the flat thimble 4. The spring acts on the supporting block, the supporting block and the flat thimble move upwards, and the supporting block drives the movable sleeve to move upwards. The fixed sleeve limits the movable sleeve to move, so that the flat thimble is limited to move. In the figure, the ejector plate has an upper layer and a lower layer, the ejector plate at the lower layer is provided with a round hole avoiding the movable sleeve, the ejector plate at the upper layer presses the movable sleeve in an initial state, and the spring is in a compressed state.
Referring to fig. 3 and 4, as a preferred structure, the bottom surface of the base 1 is provided with two mounting grooves 11, each mounting groove 11 is internally provided with a bottom plate 8, the upper side of each bottom plate 8 is connected with two movable sleeves 62, and the bottom plate 8 is locked to the mounting grooves 11 through screws 9. The bottom plate is connected with the base firmly, and the stop gear is also comparatively firm with the base connection.
After the plastic part is formed on the die, the ejector plate moves upwards for a certain distance, the spring in the movable sleeve resets at the moment, the spring drives the supporting block to move upwards, the supporting block drives the movable sleeve to move upwards, the supporting block also drives the flat ejector pin and the plastic part to move upwards, the fixed sleeve limits the movable sleeve after the movable sleeve rises to a certain height, the flat ejector pin stops moving upwards at the moment, and then other ejection devices on the ejector plate continue ejecting the plastic part.
To sum up, the utility model provides a mould ejecting device, flat thimble among this mould ejecting device can be at the effect of spring ejecting piece of moulding that makes progress down, and stop gear on the base can restrict flat thimble rebound simultaneously, has effectively prevented flat thimble from crashing the piece of moulding.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
